Description

 The invention relates to the field of road construction, and in particular to technology and pile equipment for driving and extracting metal columns from the ground, and can be used mainly in the construction and repair of road barriers.

 Known methods and coping equipment for driving and removing from the soil various types of pile elements and metal columns of barrier fences of highways (see, for example, author certificate. SU 746041, E 02 D 7/16, 1980; US Pat. No. 5,494,117 , E 02 D 7/10, 1994; US Pat. JP 63-78920, E 02 D 7/02, 11/00, 1988 according to the application JP 61-222894 of 09/20/1986, author and applicant Takeuchi Tomoeshi).

 Most of the known pile-driving equipment is a rather complex and bulky specialized installation with diesel-hammer pile loaders mounted permanently on jib cranes (see, for example, SU 746041). Such pile equipment is used mainly when immersing and removing long-sized piles from the soil at construction sites where there are no restrictions on blocking the carriageway during work. With many positive qualities, the diesel hammers included in its composition are characterized by unsatisfactory commissioning when the pile elements are immersed in weak soils and at low ambient temperature.

 The positioning and laying of the pile equipment in the transport position and the transfer from it to the working one in such installations are quite laborious. This circumstance is mainly due to the fact that the lifting equipment used in their composition has crane booms with a constant or only telescopic reach, which have much less spatial manipulation capabilities compared to multi-link articulated-lever rotary arrows of hydraulic manipulator units, and the suspension systems on them and positioning shock working body are complex in design. Installation and dismantling of the pile equipment in such installations takes a lot of time.

 Due to the peculiarities of the design and the noted drawbacks of the known pile machines of this type, it is not practical to use them for driving and extracting metal columns of road barriers from the ground.

 Free, to some extent, from many of the above disadvantages, the well-known mechanical blocker of metal racks of the fence with a hydraulic clogging device suspended on a cable according to US Pat. US 5494117. The specified downhole tool is quite simple and compact in design and does not require blocking the carriageway during the work. However, it has a significant drawback due to the need for manual orientation and retention of the driving device by the operator when immersing the columns in the ground.

 Moreover, as a result of direct contact of the operator during the immersion of the columns in the ground with a hammer-type impact device, it is exposed to vibration loads and noise, which, if it is used for a sufficiently long time, can lead to corresponding occupational diseases.

 To ensure the stable operation of most of the domestic hydraulic hammers, it is necessary to ensure that they are pressed to the driven column, the value of which, depending on the type of hydraulic hammer, can reach several hundred kilograms. To realize such a preload manually in mechanical downhole machines of the type in question is almost impossible.

 The mechanical loads that are realized when the columns are removed from the ground with the help of such pile equipment directly affect the boom equipment and the chassis of the base machine used to suspend the hydraulic hammer, which, in general, is undesirable because of their large size.

 Of the known analogues of the claimed technical solution, the closest (prototype) can serve as a "Method for driving and removing metal columns from the ground and a pile driver for its implementation" according to US Pat. JP 63-78920, E 02 D 7/02, 11/00, 1988. The copper manipulator used to carry out the known method is a highly specialized machine designed to hammer and remove metal columns from the ground, mainly during the construction and repair of automobile road barriers dear.

 Structurally, it consists of an automobile tractor mounted on it a manipulator installation, a mobile pile driver, based on a hydraulic hammer mounted on a movable carriage and a drive hydraulic cylinder for moving it, and a hydraulic system with a pump, oil tank, control valves and associated communication lines.

 The manipulator installation in its most general form is a beam mounted in the body of a truck tractor, a telescopically telescoping beam in the transverse direction, on the cantilever part of which a pivoting mast (guide frame) is pivotally mounted.

 By telescoping the said beam, the mast of the manipulator installation can be carried out plane-parallel in the transverse direction and brought to the vertical with the help of the corresponding hydraulic cylinders.

 Obviously, the execution of this beam of the manipulator installation only telescopic significantly reduces the possibility of spatial manipulation of the copra during its positioning at the site of work compared with the articulated-lever rotary arrows of hydraulic systems of crane-manipulator type.

 The copra carriage with a hydraulic hammer mounted on it is suspended by means of a chain on the rotary mast of the manipulator installation with the possibility of reciprocating movement along its guides.

 In the design of the copra of the known manipulator, there is a feeding frame pivotally mounted on a rotary mast, designed to feed columns, which can be opened and closed by rotation relative to its front surface, as well as a special mechanism mounted on the lower end of the mast for moving and stopping the captured column.

 The hydraulic cylinders of the manipulator unit and the copra, as well as its hydraulic hammer, are supplied with working fluid from an autonomous hydraulic system containing a pump with an oil tank, hydraulic distributors, and corresponding communication lines.

 The specified hydraulic system is structurally made in the form of a separate module located at the bottom of the truck tractor body, next to the manipulator installation.

 Clogging columns using this machine is as follows.

 Before leaving the place of work, the manipulator installation with the copra is transferred to the transport position, for which the telescopic extension link of the transverse beam of the manipulator installation is pulled inward and its mast is tilted down with orientation along the side of the body by means of a corresponding rotation in the horizontal plane.

 Then, the manipulator unit placed in such a way on the automobile tractor with a mobile headstock and columns laid on the bottom of the body is delivered under its own power to the site of work, the tractor is installed on the road, near its curb, parallel to the road marked for driving the columns, the pile driver is transferred from the transport position to the working position, carry out the positioning of the copra relative to the bottom, set the column in working position, ensuring it is pressed to the ground and include a copra hydraulic hammer, which clogs the column the soil to the desired depth, and then turn off the breaker and lifting it to its highest position, move the pile driver to the next position.

 At the same time, the delivery of columns to the place of work in large volumes is carried out by a separate vehicle.

 Unloading the columns at the site of the work is carried out manually, or using additional lifting means.

 Rough (preliminary) positioning of the copra of the known manipulator relative to the bottom is carried out by appropriate maneuvering of the automobile tractor.

 The final (more accurate) positioning of the copra is carried out by the corresponding spatial movement of the mast of the manipulator installation in the direction of the bottom and bringing it to the vertical using hydraulic cylinders.

 The capture and installation of the column in the working position are carried out by mechanisms specially provided for this. Lowering the carriage of the copra with a hydraulic hammer down as the column is clogged is carried out automatically, only due to the action of gravitational forces (dead weight). It was noted above that to ensure the stability of the work of most of the domestic hydraulic hammers, it is necessary to force them to be hammered into the column with effort, the value of which, depending on the specific model of the hydraulic hammer, can reach several hundred kilograms. For this reason, the use of coppers of manipulators with such kinematics of domestic-made hydraulic hammers is practically impossible.

 In the design of the well-known pile driver, there are no remote outriggers, therefore, when the mast with the pile driver extends in the direction of the bottom, a one-sided "draft" of the body occurs with its roll in the same direction and the corresponding "twisting" of the chassis of the truck tractor around its longitudinal axis of symmetry. After the mast returns to its original position, the sagging side of the body again takes its previous position.

 In this regard, to ensure the necessary power protection of the specified frame from this type of loading, a corresponding increase in its rigidity is required, or the use of special compensation devices.

 In principle, the kinematics of the copra of the known manipulator also provides the possibility of extracting, if necessary, columns from the ground by means of its carriage moving up in this case.

 One of the main disadvantages of this coper manipulator is its narrow specialization. In particular, it cannot be used in the off-season, in the intervals between “piling” operations, for example, as a normal material-handling vehicle, since the manipulator unit included in it is not suitable for loading and unloading operations.

 The design of this well-known machine and the method of driving the columns implemented with it are quite complicated with all the ensuing consequences.

 The complexity of this machine, as well as the technology for carrying out the corresponding work with it, is mainly due to the specifics of the design and kinematics of the manipulator and copra, as well as the peculiarities of its positioning at the site of work, the installation of columns in the working position, driving them, etc.

 A significant drawback of this machine is that the shock loads realized during the operation of the copra hammer directly affect the metal structure of the manipulator, actuators and control equipment of the hydraulic system, as well as the vehicle, leading to premature wear with a corresponding reduction in service life.

 Also, the corresponding power unloading of the metal structure of the manipulator unit with the automobile tractor of the known machine and when removing the columns from the ground is also not provided.

 The objective of the present invention is to remedy the above disadvantages of the prototype, namely, simplifying the design and improving the technical and operational qualities of the inventive crane manipulator, as well as optimizing the production technology (method) using hammering and removing metal columns of road barriers from the ground .

 In accordance with the invention, it is achieved by a specific set of essential features of the proposed method and device for its implementation.

 As a hammer driven tool 21 as part of the copra 9, a domestic purchased hydraulic hammer, for example, mod. NM-150 according to US Pat. RU 6579, Е 21 С 3/20, for 1997 OJSC "Tvertekhosnastka".

 The design of the working body of the percussion action in the form of a quick-detachable functionally finished mobile portable pile driver module of a mounted type based on a hydraulic hammer mounted on a movable carriage and a drive hydraulic cylinder for its movement allows you to completely abandon the highly specialized manipulator set as a part of the prototype and replace it with a more perfect one made by crane manipulator scheme with remote outriggers.

 As a result, the possibilities of spatial manipulation of the copra suspended at the end of the boom during its positioning at the site of work, especially in a cramped environment, are significantly expanded, and the universality of the machine as a whole increases, since in this case a truck tractor with this type of manipulator mounted on it quickly, without special difficulties, can be used in the off-season, between piling works, for their intended purpose, namely, for loading and unloading , Transport and other activities.

 The presence of remote outriggers in the manipulator installation can significantly increase the machine's stability against tipping over, providing the necessary power protection for the chassis of the automobile tractor 27 from the action of the corresponding operational loads, causing its frame to twist around its own longitudinal axis.

 To accommodate the manipulator unit 6 between the cab 4 and the body 5 of the automobile tractor 3, a corresponding working platform is formed by the necessary displacement of the body in the direction of the rear part of the chassis 27, made in the form of a removable short-base subframe 28 located in the resulting gap, rigidly fixed to spinal spars 29, 30 chassis.

 The specified technical solution is quite simple to implement and allows you to place the crane-manipulator between the cab and the body without shortening the latter and the need to modify the chassis of the truck tractor.

 The subframe 28 is made in the form of a welded platform, consisting of two spindle profiles 29, 30 profiled according to the configuration of the chassis 27 of the automobile tractor 3 and interconnected by a cross member 31 of the longitudinal beams 32, 33, equipped with corresponding supporting and connecting elements 34-38 and rigidly fixed to them at the back, for example, by welding with a transversely oriented service platform 39 of frame type with welded flooring 40 made of steel corrugated sheet, and two side stairs 41 with handrails 42 for lifting and lowering from it coexist personnel, steps 43 are formed from multiple, e.g., two spaced apart planar strips 44, 45 with a sawtooth profile of the working surface 46.

 Supporting and connecting elements 34-38 are used for basing and securing the subframe 28 with the manipulator 6 on the spars 29, 30 of the chassis 27 of the automobile tractor 3. In this case, two pairs of supporting and mounting elements 36 and 38 provide lateral fixation of the subframe on these chassis spars, and supporting installation elements 37 - axial fixation of the manipulator on the longitudinal beams of the subframe.

 The fastening of the crane-manipulator through the subframe provides the necessary coupling rigidity and compatibility of the deformation of the subframe and the chassis frame of the tractor under the influence of operational loads. The subframe allows you to more evenly distribute the load, due to the weight of the manipulator placed on it, along the length of the spinal spars of the chassis of the truck tractor and increase its rigidity in this area.

 The presence of two side staircases in the subframe significantly simplifies the access of working personnel to the service platform and leaving it in an extreme situation, and the design of their steps ensures reliable grip with them almost any shoe and reduces their degree of contamination, especially in adverse weather conditions. The dirt adhering to the shoes when the staff ascend the stairs relatively easily falls through the gap gaps between the rails forming them. The placement of the stairs on the subframe makes it unnecessary to properly modify the chassis of the automobile tractor.

 The subframe 28 is equipped with local stiffeners 47, made in the form of longitudinal beams 32, 33 formed at the front ends of the ramps smoothly lowering towards the cab 4 of the truck tractor 3 bevels of curvilinear configuration.

 The specified technical solution makes it possible to slightly smooth out the stiffness jumps occurring in the considered zone, due to the corresponding attachment of the subframe to the spinal spars of the chassis of the automobile tractor.

 On the connecting longitudinal beams 32, 33 of the subframe 28, the cross member 31 is fastened with bolts 48 oriented downward and opposite to the output shaft 49 of the engine tractor power take-off 3 of the cantilever bracket 50 of the beam type, in the mounting hole 51 of which the pump is mounted with fixing by means of a bolted connection 52 53 of the hydraulic system 54 of the manipulator 6, the drive shaft 55 of which, using the corresponding flange connections 56, 57 and the universal joint extension 58, is connected to the output shaft of the selection box power.

 This technical solution simplifies the installation and coupling of the hydraulic pump of the hydraulic system of the manipulator unit with the output shaft of the power take-off of the engine of the automobile tractor, since in this case no modification of the chassis frame of the latter is required, because the pump is located on a subframe opposite the output shaft of the specified box next to the oil tank 59, which allows to minimize the length of the corresponding connecting hydraulic lines of the installation by laying them along the shortest paths.

 The oil tank 59 of the hydraulic system 54 of the manipulator 6 is located on the service platform 39 of the subframe 28, in its central part, through a cushioning spacer 60 made of anti-vibration material, for example rubber, and fixed to it with two spaced apart and covering its shell along the outer contour, removable coupling clamps 61, made in the form of flexible metal bands ending with threaded tips 62, passed through the corresponding holes 63 in the metal frame of the platform, and tensioned interactions Nuts 65 connected to the connecting elements 64 of the frame and the indicated tips.

 This arrangement of the oil tank is very favorable from the point of view of its operation. He, in fact, is not thrown with road mud during the movement of the pile manipulator and does not interfere with the maintenance of the manipulator installation in the zone under consideration. Access to it is not difficult, since the side frames of the subframe are located opposite it. Attaching it to the subframe is quite simple and reliable and helps to reduce the magnitude of the vibrations acting on it, and, consequently, reduces the foaming of the working fluid in it and the amount of dirt particles deposited into the suspension to the bottom.

 The supporting and mounting platform 10 of the copra 9 is made in the form of a centrally located box-shaped base 66, equipped with three welded-on legs 70-72 of the beam type with balancing weights 73, two 70, 71 installed inside them, outfitted for its contours and ending with flat heels 67-69 of which are placed in plan at right angles to each other and are rigidly interconnected by means of a cylindrical rod 74, and the third 72 is symmetrical with respect to them.

 The presence in the structure of the supporting installation platform of balancing weights provides the necessary lateral alignment of the copra, and a cylindrical rod - significantly facilitates its tilting when moving from horizontal to vertical position and vice versa. Features of these operations are discussed in detail below.

 The struts (lanyards) 12, 13 of the copra 9, kinematically connecting its mast 14 to the supporting and mounting platform 10, are placed in the planes of its legs 70, 71, interconnected by a cylindrical rod 74, and are connected to the mast steel structure via separable spherical bearings 75, 76.

 The specified technical solution provides the necessary freedom and ease of movement of the copra mast in two mutually perpendicular planes when adjusting its spatial position manually.

 The mast 14 of the copra 9 is made of box-shaped from respectively standardly rolled or bent profiles [-shaped, and the guides 15, 16 of the mast are spaced apart with a cantilevered projection over the contours of its box and two longitudinal plates welded to it, mechanically machined after welding to final size.

 Such a design of the mast with guides is quite simple to implement, since widely available materials and technologies traditional for mechanical engineering can be used for their manufacture.

 The carriage 17 of the copra 9 is equipped with two pairs of height-spaced and fixed by bolts 77 on its back 78 removable grippers 79, 80 L-shaped in cross section of the configuration, forming in the corresponding places rectangular grooves 81 between their working surfaces and the back of the carriage under the guides 15, 16 masts 14.

 The grips of this design are simple to manufacture, as well as to install, and provide reliable retention of the carriage with a hydraulic hammer on the mast guides in the horizontal plane with the necessary freedom of movement of the carriage in the vertical plane without jamming and biting.

 The cable block system 18 of the copra 9 is made in the form of two opposite pairs of blocks 86 mounted on the ends of the mast 14 on both ends of the mast 14 mounted on the ends of the mast 14, mounted opposite to each other by means of the corresponding cylindrical axes 82, 83 and the rolling bearings 84, 85. , 87 and 88, 89 with the upper and lower ropes 90, 91 and 92, 93 covering them, looped over each other through the carriage body, and connected to the downward-oriented rod 19 of the hydraulic cylinder by means of a threaded plug 94 screwed into it, X-shaped crosspiece 95, educated of the articulated fingers 96 with ears 97, 98 of the central and two lateral yokes 99 and 100, 101, with individual screw mechanisms 102-105 for adjusting their tension built into the working shoulders of each rope, and a preloaded threaded shank 106 to the end face of the hydraulic cylinder rod, a flat supporting and supporting slider 107 with guide legs 108, 109 bent at right angles, sliding when the rod moves along the vertical mast wall 110 facing them.

 The indicated features of the design of the cable block system make it possible to realize kinematics that provide forcing the copra hydraulic hammer to the driven column with the required force at sufficiently large values without significantly increasing the mass of the copra, since it is limited by the load capacity of the manipulator at the maximum reach of the boom, or the use of special ballast weights removable type.

 The formation of a cable block system in the form of two spaced apart flat fragments can significantly reduce the diameters and, accordingly, increase the flexibility (elasticity) of the ropes included in it.

 The proposed embodiment of the mechanical connection of the ropes included in the cable block system with the end of the hydraulic cylinder rod is essentially a corresponding compensating isolation, excluding the impact of transverse (bending) loads on it when the kinematic diagram of the copra is functioning.

 To a large extent, this is also facilitated by the presence of a flat supporting support slider located in the indicated place, which serves as a movable lunette.

 The presence of individual screw mechanisms in the working arms of each of the ropes of the copro cable system significantly simplifies the problem of adjusting their tension.

 On the lower cut of the carriage 17 of the copra 9, a trunk 111 coaxially located with the hydraulic hammer 21 is formed with vertically oriented guides 112-115 to accommodate the removable head rests 116, with the possibility of reciprocating movement, the upper surface 117 of which interacts when the hydraulic hammer works with its flat end 118 the shock part 119, and on the lower surface 120, a recess 121 is formed to capture the upper end of the driven column 2 of the corresponding profile, made along its outer contour.

 At the lower end of the mast 14 of the copra 9, a cantilever holder 122 coaxially located with the headband 116 is rigidly fixed, equipped with plug-type replaceable guide brackets 123 open on the installation side of the clogged posts 2, the pharynx of each of which is profiled along the outer contour of the column of the corresponding configuration.

 The use of interchangeable headrests and guide brackets for holding the hammered columns in the copra can significantly expand the corresponding capabilities of the coper manipulator depending on their geometric parameters (see Fig. 79).

 On the mast 14 of the copra 9 above the upper cut of the struts 12, 13, within the visual visibility from the ground level, a two-coordinate indicator 124 of the mast deviation from the vertical is installed, which greatly simplifies the control of its spatial position during the positioning of the copra.

 The mast 14 of the copra 9 is equipped with an indicator 125 of the height of the rise (lowering) of the hydraulic hammer 21, for example, made in the form of a measuring ruler fixed to it. The presence of such an indicator greatly facilitates the determination of the moment the copra is turned off when the driven column is immersed in the soil to the required depth.

 At the upper end of the mast 14 of the copra 9, under the corresponding blocks 86, 87 of the cable block system 18, from the side of the carriage 17, a two-legged side support 126 of the arch type is welded, equal in height, relative to the longitudinal axis of the mast, radial extension of the legs 70, 71 of the support installation platform 10, interconnected by a cylindrical rod 74.

 The specified support in conjunction with the supporting heights 67, 68 of the legs 70, 71 of the support and mounting platform 10 provides the necessary stability of the pile in a horizontal position during storage and transportation.

 On the cylindrical axis 82 of the attachment of the upper blocks 86, 87 of the cable system 18 of the copra 9, between the corresponding ears 127, 128 of the mast 14, a pivoting ring 129 is mounted with a pivotally axially fixed cylindrical pin 130 with a removable flexible suspension bracket 131 fixed to the end boom 8 used to transfer the copra manipulator 6 by a pivot 132, equipped with a locking lock, for example, spring type.

Flexible suspension 131 can be made in the form of rope or chain links, or consisting of two articulated levers of cardan traction, equipped with
corresponding connecting elements. Structurally, the flexible rope suspension can be single-branch, ending with the corresponding connectors to the boom 8 and earring 129 (see Fig. 77), or two-branch (see Fig. 74, 76, 78). In the latter case, the finger 130 is not required, since the suspension rope is passed directly through the ear of the earring. Implemented in the design of the inventive koprovogo manipulator, the method of suspension of the copra at the end of the boom of the manipulator installation completely eliminates the possibility of unauthorized uncoupling of the copra with it when performing pile driving and tilting. In addition, thanks to the flexible suspension, the boom of the manipulator installation practically does not directly participate in piling. In this case, it performs only the safety function, ensuring guaranteed retention of the copra in case of its possible unauthorized deviation from the gravitational vertical. At the same time, shock loads and vibrations realized during the operation of the copra hydraulic hammer are practically not transmitted to the boom of the manipulator installation and the chassis of the automobile tractor.

 The carriage 17 of the copra 9 is equipped with a removable two-position removable grip 133 for removing the columns 2 from the soil 1, made in the form of a central rod 134 that is self-aligning along the action line of the pulling force with a threaded shank 135, which is fixed to the lower cut of the carriage on the shoulder from the guide masts, which is the least possible for structural reasons using a package of spherical washers 136 and lock nuts 137, with a traverse 138 suspended on it, on which are placed, with the possibility of discrete adjustment of the spatial position, fix overhead eyes 140, which are bolted by bolts 139, with eyelets pivotally attached to them by means of cylindrical fingers 141 with two earrings 142, 143 enclosing the column from the sides and passing through them and corresponding holes 144 in the column walls with a transversely oriented removable king pin 145 equipped with a locking locking mechanism 146, for example spring type, from unauthorized loss of it from these holes, connected to the yoke with a flexible suspension 147, for example, a chain.

 As part of the hydraulic system 22, the copra 9 is provided with an adjustable pressure relief valve 148 fixed to the mast 14 metal structure for adjusting the force realized by the hydraulic cylinder 20, the pressed hydraulic hammer 21 to the hammered column 2, and communication lines 23-26 from the hydraulic cylinder and the hydraulic hammer of the hydraulic system are laid along the mast towards its upper end with fixation by means of bolts 149 pressed by bolts 150 grips and the formation of the necessary loops of sagging 151, 152 and the bundle 153 protruding beyond its cut flexible shanks corresponding lengths ending with quick-release squeezing valves 154 for connecting them to the hydraulic system 54 of the manipulator 6.

 In each of the communication lines 23-26 of the hydraulic system 22 of the copra 9, corresponding connectors 155-158 are provided for connecting pressure measuring instruments to them, for example, when adjusting its operation parameters or testing, sealed with removable plugs.

 The presence in the hydraulic system 22 of the pressure reducing valve 148 and the connector 156 greatly facilitates the problem of the prompt selection of the required amount of force, the pressed hydraulic hammer to the column driven into the ground. The communication lines of the copra fixed to the steel structure of the mast do not spoil its appearance, without special difficulties they are connected to the hydraulic system of the manipulator installation and undocked, if necessary, from it in just a few minutes and provide the necessary freedom of movement along the guides of the mast of the carriage with a hydraulic hammer and spatial manipulations with the copra in General when doing work.

 At the bottom of the body 5 of the truck tractor 3 at an equal distance from its lateral sides 159, 160, a flat frame 162 of a rectangular configuration, made of two, spaced apart from each other and closed at their ends by welded transverse beams 163, 164 longitudinal guides 165, is rigidly fixed with bolts 161 , 166 [-shaped sections facing each other with the open ends of their shelves 167, 168, inside of which a trolley-tilter 169 copra 9 is arranged to move in the longitudinal direction, interacting in its extreme positions with its oynymi elements 170 fastened with screws 171, on the inner walls of cross beams of the frame detachable buffers 172-175, each of which is designed as a corresponding set of shims 176 and the convex 177 of the shock absorber elastically deformable material such as rubber.

 The buffers 172-175 are designed to stop the trolley-tilter 169 in extreme positions when tilting the copra and amortizing the collisions of the fenders 170 that are realized with them. In this case, the simultaneous contact of the front or rear pairs of fenders with the corresponding pairs of buffers is ensured constructively by selecting the necessary adjusting gaskets 176.

 The tilt truck 169 copra 9 is made in the form of a biaxial platform 178 with four running wheels 179-182 and side rollers 183-186 of antifriction material, for example, polyamide, interacting with the corresponding surfaces 187, 188 of the longitudinal rails 165, 166 of the flat frame 162, and welded to it from above by two, located opposite each other and spaced apart in the transverse direction, supports 189, 190 with vertically oriented through-through coaxial grooves 191 of a U-shaped configuration with cut-off angled entry kami 192, 193 in their side walls 194, 195, profiled according to the outer diameter of the cylindrical rod 74 introduced into them during tilting of the copra 9, connecting the legs 70, 71 of its support and mounting platform 10, which are placed at right angles to each other and overlapping at the entrance locking heads 196 spring-loaded bolts 197 rigidly fixed to the metal structures of these supports of high-speed on-off clamps 198, equipped with upward inclined bevels 199.

 The presence of side rollers 183-186 in the undercarriage of the trolley-trolley 169 and the selection of the appropriate distance between the longitudinal guides 165, 166 of the frame 162 ensure its unhindered movement along them without jamming and visually fixed transverse play (yaw).

Spring-loaded crossbars 197 of quick-acting two-position latches 198 of the trolley-tilter 169 copra 9 are placed in the internal cavities of their bodies 200 with the possibility of rotation around the longitudinal axis by 90 ^o and reciprocating along it within the width of the U-shaped grooves 191 of the supports located on the trolley-tilter 189, 190, for which purpose a centrally located through-the-edge open-end cut 202 of a V-shaped profile with a formation at the ends is formed in the trailer 201 of the cantilever part of the housing of each of the clamps x at the same time, in the body of the trailer of the wedge-shaped protrusions 203, 204 oriented in opposite directions of the flat support and installation half-sites 205, 206 ending in lateral limiting flanges 207, 208 smoothly conjugated with them (in radius), equidistant from the vertical plane of symmetry 209 by half the diameter of the interacting with them, with a corresponding rotation of the bolt 197 of the ends 210, 211 pressed into the middle part of its shank 212, parallel to the inclined bevel 199 of the locking head 196, of the cylindrical pin 213, cantilever in stepping over the contours of said shank.

 On the end part of the shank 212 of the bolt 197 of each of the quick-acting two-position clamps 198, for example, by means of a pin 214, a lever-type handle 215 kinematically interacting when removing the headstock 9 from the supports 189, 190 of the tilt-trolley 169 with a cylindrical hinge 216 fixed to one of their side walls 195 with the possibility of rotation in a vertical plane parallel to the longitudinal axis of the latch, two-beam beam 217, the departure of the working shoulders of which in plan overlaps the zone of location of the lever important handle of the lock and U-shaped grooves 191 in the supports of the trolley-tilter.

 The presence of flanges 207, 208 eliminates the possibility of accidentally slipping the ends of the pins 210, 211 of the pins 213 from the half-sites 205, 206, which are sufficiently short in length when the knobs 215 are manually rotated, and the presence of the rocker arms 217 ensures that these ends automatically collide with the half-sites and the corresponding turn of the handles the opposite direction when removing the copra 9 from the supports of the trolley-tilter

 This technical solution provides a quick, literally within a few minutes, and safe tipping of the copra when moving the declared manipulator from the transport position to the working one and vice versa using the manipulator installation, as well as its appropriate placement and fixing in the back of a truck tractor.

 At the bottom of the body 5 of the truck tractor 3, away from the middle part of one of the longitudinal guides 166 of the flat frame 162 opposite the pivot rack 218 of the manipulator unit 6 is rigidly bolted 219 with the ability to adjust the angular position in the vertical plane of the two-position pivot bed 220 for laying and fixing the folded boom 8 in transport position without copra 9. Lodgement 220 is made in the form of a flat base 221 with corresponding connecting elements and transversely oriented onnoy wall 222 provided with two pairs of lugs 223, 224 and 225, 226 in which the axis 227 by means of hinged tilting strut 228.

 The hinged stand 228 of the cradle 220 consists of two spaced apart side cheeks 230, 231 that are joined together by means of the welded cross-member 229 and the starting edges 232, 233 bent outward and parallel to them are located on the inner side of the ribs 234, 235 with welded in the middle part between them are supporting bridges 236, 237, which together with the adjacent walls of the indicated cheeks and ribs form two receiving boxes 238, 239 with a wedge-shaped entrance. Lodges 238, 239 are profiled along the external contour of the flat mounting elements 242, 243 of the boom 8 inserted into them and fixed with the help of pivots 240, 241, in which the corresponding longitudinally oriented docking grooves 244 are formed, which are laid when it is laid on the lodgment 220 coaxially with the walls lateral cheeks 230, 231 and ribs 234, 235 of the hinged post 228 in diameter of the pivots 240, 241 through holes 245, near which on the outer surface of the cheeks L-shaped stops 246 are welded to fix the pivots in a bayonet-like manner.

 In the zone of location of the eyes 223, 224 and 225, 226 of the inclined wall 222, adjusting bolts 247 are screwed into it, interacting with the corresponding stops 248 of the folding stand 228 facing them.

 These bolts allow you to adjust the angular position of the hinged stand 228 tool tray 220 in a vertical plane. Due to this, the combination of the angle of inclination of the supporting jumpers 236, 237 of the folding stand and the mounting surfaces of the elements 242, 243 of the boom 8 of the manipulator unit 6 when laying it in the body 5 of the automobile tractor 3 without a copra 9 does not cause any difficulties. The boom is laid on the lodgement quickly and with a fairly reliable fixation.

 In the free position, the folding stand 228 of the cradle 220 is rotated around its axis 227 and lowered to the bottom of the body 5 of the truck tractor 3.

 This technical solution provides quick installation and reliable fixation of the folded boom of the manipulator installation in the back of a truck tractor without a copra suspended on it and the same translation into working position when using a tractor with the specified installation in between piling operations, for its intended purpose.

 As a hydraulic drive, the copra 9 in the inventive coprovoy manipulator uses the hydraulic system 54 of the manipulator 6 with the standard hydraulic distributors P3, P6 of remote control of the operation of its hydraulic cylinder 20 and hydraulic hammer 21 s included in one of its hydroblocks A2 (see Fig. 71, item 249) 250 operator post. In this case, both communication lines 23, 24 of the hydraulic cylinder 20 and the pressure line 25 of the hydraulic hammer 21 copra 9 are connected to the corresponding standard lines 251-253 of the hydraulic system 54 of the manipulator unit via quick-release valves 154 and 254, and the drain line 26 of the hydraulic hammer is made larger in diameter of the passage section , laid on the metal structure of the boom 8 with fixing in place and the formation of the necessary slack, providing unobstructed spatial manipulation of the boom with a suspension suspended on it rum within its maximum emission in operation and when transferring it from the transport position to the working and back without detaching the said communication lines of the hydraulic manipulator, and directly, bypassing the distributor P6 is connected to the oil tank 59 of the latter. The specified increase in the diameter of the flow cross section of the hydraulic hammer drain line in conjunction with its connection to the oil tank directly allows minimizing the hydraulic resistance of this hydraulic line in order to avoid a decrease in the hydraulic hammer operation efficiency.

 The use of a hydraulic system of a manipulator installation as a hydraulic drive of a copra with standard remote control valves for the operation of its hydraulic hammer and a drive hydraulic cylinder from the operator's post, in combination with the features of its circuit design with the supply lines of the latter, is very convenient for the user, since in this case it is possible to refuse to create an additional independent their power circuit, which would entail the corresponding complication and appreciation of the machine.

 The absence of the need to undock the power lines of the hydraulic hammer and the driving hydraulic cylinder of the copra during the tilting operation, as well as the piling work, significantly contributes to increasing the productivity of the inventive pile manipulator and ensuring the necessary convenience of its maintenance.

 The layout of the inventive pile manipulator with the transport unit 6 attached to the end of the boom 8 of the manipulator unit 6 of the copra 9 is made by horizontally stacking the copra with the support and mounting platform 10 in the supports 189, 190 of the tilt-tipper 169 towards the cab of the tractor unit 3 with the platform locked in them using quick-acting two-position clamps 198 and side support 126 of arch type on the floor of the body 5 with the subsequent transformation of the boom, without undocking the hydraulic communication mag trawl 23-26 kopra, in one line with lowering to the rear side of the body and laying with the remote section 255 on a 256 profile lodgement 257 made in the form of a U-shaped support with bent cantilevered to the mast 14 of the copra mast 256, made in the form of a U-shaped support outwardly by the lead-in edges 258, 259 of the side walls and placed on its bed with a flat supporting spacer 260 of an antifriction material, for example, polyamide.

 The specified design and layout solution provides a rational installation of the boom 8 of the manipulator unit 6 in the body 5 of the automobile tractor 3 along the longitudinal axis of symmetry with support on the pile driver 9, leaving free areas located on its sides that can be used to accommodate clogged columns. This arrangement makes an attractive appearance of the inventive crane.

 In the transport position without copra 9, the folded boom 8 of the manipulator unit 6 with the automatic coupler between its remote and lifting sections 255, 261 is stacked by their articulated joint on a two-position rotary tool tray 220 mounted in the body with the boom fixed in it using pivots 240, 241.

 The indicated technical solution ensures the rational laying and fixing of the folded boom of the manipulator in the back of a truck tractor without a copra suspended on it and located on the bottom of the platform body with a trolley trolley, as well as the maximum release of the bottom platform of the body to accommodate the loads transported between breaks between piling operations.

 Clogging of the columns 2 into the soil 1 using the inventive pile driver is as follows.

 A manipulator unit mounted on an automobile tractor 3 with a mobile headstock and columns 2 is delivered on its own to the work site and a vehicle tractor is placed on the road, near its curb, parallel to the road marked for driving the columns.

 In this case, before starting work, turn on the pump 53 of the hydraulic system 54 of the manipulator 6 and experimentally verify the actual value of the force, the hydraulic hammer 21 is pressed by the hydraulic cylinder 20 of the carriage 17 to the column 2 from the condition of ensuring a stable position of the copra 9 during its driving, followed by adjustment, if necessary, settings which is part of the last pressure reducing valve 148, which provides the corresponding pressure in the rod cavity 262 of the hydraulic cylinder, equivalent to the specified force.

 For the convenience of the work, this operation can be performed in the transport position of the pile manipulator with the horizontal orientation of the copra 9 in the body 5 of the truck tractor 3.

 Before its implementation, first, having first removed the plug from the connector 156 of the communication line 24 of the hydraulic system 22 of the copra 9, a corresponding pressure meter, for example, of a indicating type, is connected to it.

 Then, when the pump 53 is turned on, by moving the control handle of the hydraulic distributor P3 of the hydraulic system 54 of the manipulator unit 6, the working fluid is supplied to the rod cavity 262 of the hydraulic cylinder 20 of the carriage drive 17 of the copra 9. In this case, the rod 19 of the hydraulic cylinder 20 is retracted by the pressure of the working fluid into its housing 263, by means of the ropes 95, 92, 93 attached to the beam 99 fixed to it, it moves the carriage 17 through the blocks 88, 89, the carriage 17 to the leftmost position (in the direction of the cab 4 of the vehicle tractor 3). In this position, using the aforementioned meter, the value of the pressure shown by him is visually recorded and according to it, taking into account the known geometric dimensions of the piston 264 and the rod 19 of the hydraulic cylinder 20 of the copra 9, the actual value of the force developed by it is drawn, the hammered column 2 to the ground 1. If it corresponds to the required, then this verification ends. The pressure meter is undocked from the connector 156 and the latter is sealed with a plug.

 If the actual value of the thus determined force deviates, the pre-hammered column is pressed to the ground from the required value, this discrepancy is eliminated by appropriate adjustment (adjustment) of the pressure reducing valve 148 of the hydraulic system 22 copra 9.

 The need for such verification arises mainly after large interruptions in the work of the copra, or after using the coper manipulator for another purpose with the dismantling of the specified working equipment, for example, for lifting and handling operations.

 At high values of the force of pressing the copra hydraulic hammer to the driven column, which are close in absolute value to the total weight of the copra, it can behave unstably during the driving of the columns. To do this, in fact, an appropriate check is carried out and, if necessary, an adjustment of the magnitude of the indicated effort to the necessary level, ensuring stable operation of the copra.

 In principle, this check can also be carried out in advance at the site of the permanent deployment of the pile driver.

 At the end of the check, the copier and the coper are transferred from the transport position to the working one.

 At the same time, the outriggers 7 of the manipulator unit 6 are first taken out to the required distance in the transverse direction, they are turned with the heel of the bearing down and by the movements of the hydraulic valves P7, P8 of the corresponding hydraulic unit A3 (see Fig. 71, item 249) its hydraulic system 54 is lowered all the way into the road the canvas. Then, using the control valves of the hydraulic valves P1, P2, P4, P5 of the hydraulic unit A2, by means of appropriate manipulations with the arrow 8 of the manipulator unit 6, the upper part of the driver 9 is lifted by the flexible suspension 131 articulated with the earring 129, and turning it relative to the hinge 265 formed in kinematic engagement with each other, with a cylindrical rod 74 of the support and mounting platform 10 of the copra 9 and U-shaped grooves 191 of the supports 189, 190 of the tilt trolley 169, the coper is moved from a horizontal position to a vertical one.

 When performing this operation moving on guides 165, 166 located in the body 5 of an automobile tractor 3 of a flat frame 162 to its rear side, the tilt truck 169 with a pile 9 pivotally mounted on it stops in the extreme right position with buffers 174, 175 interacting with the corresponding fenders 170 of its design.

After tilting, the copra 9 is manually rotated 90 ^° (from vertical to horizontal) on the handle 215 of the latches 198. When the handle 215 is rotated, the bolts 197 and the ends 210, 211 of the pins 213 of the latches are respectively fixed.

 The ends 210, 211 of the pins 213, kinematically interacting when turning the handles 215 with the side edges 266 of the inclined faces of the slots 202 in the ends of the 201 of the housing 200 of the clamps 198 and overcoming the resistance of the compressing springs 267, move the bolts 197 to the extreme left position. In this case, the heads 196 of the crossbars are recessed into the internal cavities of the bodies 200 of the latches 198, releasing the outputs of the U-shaped grooves 191 of the supports 189, 190 of the trolley 169 that they have previously locked.

 At the end of the rotation of the handles 215, the ends 210, 211 of the pins 213 are brought out on the supporting half-plates 205, 206 and abut against the restrictive flanges 207, 208 of the wedge-shaped protrusions 203, 204 formed in the bodies of the end-members 201 of the cantilever parts of the housing 200 of the latches 198.

 After that, by lifting the boom 8 of the manipulator 6, the pile driver 9 is removed from the supports 189, 190 of the trolley 169.

When performing this movement, the cylindrical rod 74 of the support and mounting platform 10 of the copra 9, leaving the U-shaped grooves 191 of the supports 189, 190 of the trolley-tilter 169, touches the console ends 268 of the rocker arm 217 above it and deflects them upward. The rocker arms 217, turning relative to the axes of the hinges 216, engage with their opposite cantilever ends 269, which diverge downward, into engagement with the latches 215 of the latches 198 located horizontally below them and rotate them in the opposite direction. At the same time, the ends 210, 211 of the pins 213, the bolts 197 of the clamps come off the supporting half-sites 205, 206 and, sliding along the lateral edges 266 of the inclined faces of the slots 202 in the ends of the 201 casings 200 under the action of expanding springs 267, fall to the bottom 270 of the slots 202. Moving simultaneously with the Unlock crossbars 197 clamps 198 are rotated by 90 ^o in the opposite direction of sloped ramps 199 of locking head 196 upwardly, which extends from the housing cavity 200 is automatically released overlap outputs of U-shaped grooves in the bearings 189, 190 m maturation-tilting device 169.

 After removing the trolley 169 from the supports 189, 190 of the trolley 169, the pile driver 9 suspended at the end of the boom 8 of the manipulator unit 6 is transferred by means of appropriate manipulations in the direction of clogging of the first column 2 and is positioned relative to the bottom.

 The positioning of the copra 9 in the circumferential direction is carried out by manually turning it on the flexible suspension 131 pivotally mounted on the end of the boom 8 of the manipulator 6, followed by lowering the support and mounting platform 10 in the indicated position on the ground 1. The position of the copra is visually monitored.

 The positioning of the copra 9 relative to the gravitational vertical is carried out by means of corresponding alternate angular movements in two mutually perpendicular planes pivotally mounted on the support and mounting platform 10 of the mast 14 with the help of kinematically screwed turnbuckles 12, 13 connecting them together. When the threaded couplings 271 turnbuckles 12, 13 are rotated, corresponding their length, and therefore the angle of deviation of the mast 14 from the vertical, changes in this way. The control of the spatial position of the copra mast when performing this operation is carried out visually by the bi-coordinate indicator 124 fixed on it, deviating it from the gravitational vertical.

 At the end of the positioning of the copra 9 by means of the corresponding movement of the control handle of the hydraulic distributor P3 of the hydraulic unit A2 of the hydraulic system 54 of the manipulator unit 6, the working fluid is supplied to the piston cavity 272 of the hydraulic cylinder 20 of the carriage drive 17 with the hydraulic hammer 21 fixed to it. Moreover, the rod 19 of the hydraulic cylinder 20 is extended from its housing 263 under the pressure of the working fluid acting on the piston 264, it moves by means of the crosses 95, 90, 91 attached to the rocker arms 100, 101 of the crosspiece fixed thereon, thrown over the block ki 86, 87, the carriage 17 with a hydraulic hammer 21 to its highest position.

 Then set the clogged column 2 in the working position with the provision of a corresponding tightened it to the ground 1.

 The installation of the column 2 in the working position is carried out manually by entering its upper end into the corresponding recess 121 of the headrest 116 of the carriage 17 of the copra 9, and the lower one into the guide bracket 123 of the holder 122 fixed on the mast 14 with the ground 1 and pressing the brackets against the back 273.

 After that, holding the column 2 in the indicated position with your hands, the hydraulic hammer 21 is pressed by the corresponding lowering of the carriage 21 through the headgear 116 to the upper end of the column.

 The specified operation is carried out by supplying the working fluid to the rod cavity 262 of the hydraulic cylinder 20 by correspondingly moving the control handle of the hydraulic distributor P3 of the hydraulic unit A2 of the hydraulic system 54 of the manipulator unit 6. In this case, the rod 19 of the hydraulic cylinder 20, being pulled under the working fluid pressure acting on the piston 264, lowers with the help of the ropes 95, 92, 93 connected to the beam 99 fixed to it by the crosspiece, thrown through blocks 88, 89, the carriage 17 with the hydraulic hammer 21 down.

 When lowering the carriage 17, the flat end 118 of the shock part 119 of the hydraulic hammer 21 is brought to the upper surface 117 of the headrest 116 and presses the driven column 2 into the ground 1 with the necessary force. In this case, the column automatically occupies a strictly vertical position in space, fixed by headrest 116 and bracket 123 .

 This technical solution is quite simple to implement and does not require the positioning of the copra and the exhibition of the hammered column in the initial position of the corresponding special mechanisms with complex kinematics, as in the prototype. In essence, it allows you to completely abandon them by switching to manual positioning and exhibition, and on this basis, greatly simplify the design of the declared crane, improve weight perfection and reduce its cost.

 After verifying the correctness of the exhibition of the driven column to the ground 1, the maintenance personnel leave the working area (assigned to a safe place), and the copra is further controlled remotely from workstation 250 of the manipulator 6 operator.

 After this include a pile driver 9, a hydraulic hammer 21 which clogs the column 2 into the soil 1 to the required depth.

 The inclusion of the copra 9 is carried out by simultaneously activating its hydraulic hammer 21 and the hydraulic cylinder 20 of the carriage drive 17 by corresponding movements of the handles of the valves P6, P3 of the hydraulic unit A2 of the hydraulic system 54 of the manipulator unit 6.

 When moving the control handle of the hydraulic distributor P6, the working fluid from the hydraulic system 54 of the manipulator 6 through the communication line 253, squeeze valves 254, 154, the communication line 25 and the control unit 274 of the hydraulic hammer 21 is fed under the piston of its hammer 275 and the latter, moving upward, compresses the gas in the air spring accumulator 276. In this case, the working fluid located above the piston of the striker 275 is displaced through the drain communication line 26 of the hydraulic system 22 copra 9 directly into the oil tank 59 of the hydraulic system 54 installation 6.

 At the end of the platoon, the hammer of the hammer 275 opens a corresponding hole in the sleeve 277 of the hydraulic hammer 21, through which the working fluid from the pressure line is supplied under the end of the plunger 278 of the control unit 274. At the same time, the pressure of the working fluid in the cocking and overflow chambers of the hydraulic hammer 21 is aligned and the hammer 275 under the gas pressure in the air spring begins to accelerate downward.

 At the end of the working stroke, the striker 275 strikes the shank 279 of the shock part 119 of the hydraulic hammer 21, interacting with its flat end 118 with the upper surface 117 of the headrest 116 worn on the driven column 2.

 The piston of the hammer 275 opens the corresponding hole in the sleeve 277 and under the action of compressed gas the plunger 278 returns to its initial position and then the specified operation cycle of the hydraulic hammer 21 is repeated many times.

 The energy realized during the shock is transferred from the headgear 116 to the clogged column 2 and the latter is immersed in the ground 1 with the necessary speed.

 When moving the control handle of the hydraulic control valve P3, the working fluid from the hydraulic system 54 of the manipulator 6 through the squeeze valves 254, 154 and the communication line 24 is fed into the rod cavity 262 of the hydraulic cylinder 20 of the copra 9. In this case, the rod 19 of the hydraulic cylinder 20 is pulled under the working fluid pressure acting on the piston 264 into the housing 263, synchronously lowers the carriage 17 with the help of the cable system 18 connected to it, providing a constant forced preload with the necessary force of the hydraulic hammer 21 to 1 st immersed in the ground olbica 2.

 Implemented by simultaneously turning on the hydraulic hammer and the drive hydraulic cylinder for moving it, the copra operation feature is very important for large values of the indicated forces, mainly characteristic of domestic-made hydraulic hammers, when the own weight of the hydraulic hammer is not enough for this.

 The boom 8 of the manipulator 6 does not participate in this process, remaining stationary all the time. She, in this case, performs only the safety function, ensuring guaranteed retention of the copra 9 in the event of its unauthorized tilt. In this case, the shock loads realized during operation of the hydraulic hammer 21 on the boom and chassis 27 of the truck tractor 3 of the coping manipulator are practically not transmitted.

 At the end of driving the column 2 into the soil 1, by corresponding movements of the control valve of the hydraulic distributor P3, they reduce the frequency of striking it with the hydraulic hammer 21, up to single, and visually controlling the depth of immersion of the column in the soil using the indicator 125 fixed on the mast 14 of the copra 9, at the moment of reaching its predetermined value give a command to the operator of the manipulator to turn off the copra.

 This technical solution greatly facilitates the operator's visual determination of the moment of completion of clogging of the column and minimizes the likelihood of excessive penetration into the ground.

 Switching off the copra 9 is carried out from the operating station 250 of the operator of the manipulator unit 6 using the control valves of the hydraulic valves P3, P6.

 At the end of clogging of the first column, the carriage 17 with the hydraulic hammer 21 is discharged to the upper position as described above and the coper 9 is transferred to the next position (to the place of clogging of the second column) using the boom 8 of the manipulator 6 and the entire above process is repeated.

 From one installation of the truck tractor 3 of the coper manipulator, successively transferring, by means of appropriate manipulations, the arrows 8 of the manipulator unit 6 of the pile driver 9 from position to position, the batch of columns 2 is driven in the reach of the arrow, after which, without disconnecting the hydraulic communication lines of the copra from the hydraulic system of the manipulator installation, Koprovy manipulator in transport position with laying the copra in the truck tractor body and move to a new site of work.

 The transfer of the pile driver from the working position to the transport is carried out in the following order.

 First, along the guides 165, 166 of the frame 162, the tilt-trolley 169 is manually moved to the extreme right position (in the direction of the rear side of the body 5 of the automobile tractor 3). Then, by manipulating the boom 8 of the manipulator unit 6, the pile driver 9 is lifted and transferred to the trolley-tilter 169 location zone, after which, having oriented it with the cylindrical rod 74 of the supporting and mounting platform 10 opposite the U-shaped grooves 191 of the supports 189, 190, they are placed on the trolley- tilter. When the copra 9 is lowered onto the tilt trolley 169, the cylindrical rod 74 presses the ends 268 of the rocker arm 217 of the supports 189, 190 and they, turning relative to the axes of the hinges 216, deviate downward and pass the rod towards the inclined bevels 199 of the locking heads 196 of the bolts 197 of the latches 197 of the clamps 198.

 When meeting with the inclined bevels 199 of the locking heads 196, the cylindrical rod 74 squeezes them, recessing them into the internal cavities of the housings 200 of the latches 198, and lowers to the bottom of the U-shaped grooves 191 in the supports 189, 190 of the tilt trolley 169.

 After falling of the cylindrical rod 74 into the indicated zone, the locking heads 196 of the crossbars 197 under the action of the springs 267 automatically return to their original position and, blocking the exits from the U-shaped grooves 191, fix the support-mounting platform 10 of the copra 9 in the supports 189, 190 of the trolley-tilter 169 .

 After that, by appropriate manipulations of the boom 8 of the manipulator unit 6, deflecting the top of the pile driver 9 downward in the direction of the rear side of the body 5 of the automobile tractor 3 and turning it relative to the hinge 265, move the trolley 169 along the guides 165, 166 of the frame 162 in the direction of the cab 4 of the tractor and put the top of the copra on the floor of the body with 5 legs of the support 126.

 The trolley-tipper 169 moving when laying the copra in the body of the automobile tractor along the rails 165, 166 is braked in the extreme position by the buffers 172, 173 interacting with its front fender elements 170.

 In this position, the coper 9 occupies a horizontal position and rests with a cylindrical rod 74 on the bottom of the U-shaped grooves 191 of the supports 189, 190 of the tilt trolley 169, and the legs of the support 126 on the floor of the body 5 of the automobile tractor 3.

 After laying the copra 9 in the body 5 of the automobile tractor 3 the boom 8 of the manipulator 6 without undocking the hydraulic communication lines 23-26, they are transformed into a single line with a lowering to the rear side of the body and laying with the remote section 255 on the profiled lodgement 257 of the copra, profiled by its outer contour.

 Then, acting in the reverse order, the remote outriggers 7 of the manipulator unit 6 are returned to their original position with the support heels up, after which the coper manipulator is ready to move to a new section of the road to be equipped.

 The parameters of the copra work are largely determined by the characteristics of the hydraulic drive used (hydraulic system 54 of the manipulator 6) and can, if necessary, be varied to a certain extent, for example, by a corresponding change in the speed of the pump 53 and the nature of the movement of the control valves of the control valves P3, P6.

 To remove the columns 2 from the soil 1, use the two-position gripper 133 with a removable king pin 145. In this case, when removing the columns from a sufficiently dense soil, when near-limit loads are realized, use the gripper installation scheme 133 on the carriage 17 in position 1 at the minimum possible departure from its back 78 where the metal structure has a maximum bearing capacity (see Fig. 43).

 When removing the columns from less dense soils, when the nominal and minimum loads are realized, the installation pin king pin 145 of this gripper can be used in position 2, directly between the guides 114, 115 of the through grooves in the walls of the carriage trunk 111 under the raised headrest 116 (see Fig. 44).

 When removing from the ground, the upper end of column 2 is engaged by means of a gripper 133 (at position 1, see Fig. 43) or its king pin 145 (at position 2, see Fig. 44) with a copra carriage and the lower part of the column, buried in the ground, is pulled out of him the corresponding lifting of the carriage 17 using the hydraulic cylinder 20. The specified operation is favored by the orientation of the hydraulic cylinder 20 with the rod 19 downward, so that they can develop the maximum possible traction.

 This technical solution is quite simple to implement. It allows without special difficulties to carry out all work associated with the extraction of incorrectly clogged or damaged columns, as well as with their planned replacement. At the same time, quasistatic loads of a very large magnitude, realized in the process of these works, in contrast to the prototype, are practically not transferred to the manipulator installation and the chassis of the automobile tractor, since in this case they are closed directly to the metal structure of the corresponding parts of the copra itself.

 The structural layout of the inventive pile driver in the transport position without a copra is usually implemented at relatively large interruptions in the work on the arrangement of roads. In this case, the flexible suspension 131 is undocked from the boom 8, and the communication lines 23-26 copra from the corresponding highways of the hydraulic system 54 of the manipulator installation and horizontally stacked at the storage location.

 After that, another working body, for example, a hook 280 or a grab, which allows you to use this machine for other, for example, hoisting-and-transport operations, can be suspended on the released boom 8 of the manipulator installation.

 The indicated feature of the structural and layout construction of the inventive pile manipulator allows one to practically completely eliminate the forced downtime of the automobile tractor and the manipulator unit that is part of it during off-season periods, which is important for the user of this equipment.

 In General, the inventive method of driving and removing metal columns from the ground, mainly during the construction and repair of road barriers and a pile driver for its implementation are quite simple to implement. Thanks to the above-mentioned features of the design of the said pile equipment, its necessary compactness, high maneuverability, reliability and safety in operation and ease of operation are ensured.

 When arranging roads using the inventive equipment and technology of these works, their carriageway does not overlap.

 In the process of performing work related to driving and removing metal columns of road barriers from the ground, it is easily transferred from the transport position to the working position and vice versa.

 In this case, it is not necessary to undock the hydraulic communication lines of the copra from the corresponding lines of the hydraulic system 54 of the manipulator unit both when performing the indicated operations and directly when driving and removing the columns from the ground.

 The positioning of the copra when performing work performed using the specified copier manipulator is extremely simple and not difficult.

 The inventive method and the coper manipulator for its implementation due to its specificity provides a fairly high performance both when driving the columns of the barrier fences of roads, and when removing them from the ground.

 At the same time, shock and quasistatic loads realized in the process of performing these works are practically not transferred to the boom equipment of the manipulator installation and the chassis of the automobile tractor.

 The operation of the inventive pile equipment when driving the columns into the ground is accompanied by a relatively low noise level not exceeding the permissible sanitary standards, and due to the fact that the maintenance personnel may be at some distance from the place of work, there is practically no harmful effect on it.

 Due to the use of high-quality domestic hydraulic element base in the designs of the copra manipulator and the manipulator unit, the equipment has the necessary environmental cleanliness.
