(54) PORK COUPER

I

. The invention relates to pile engineering, and more specifically to the installation of pile driving machines designed in dp-; Pile foundations in bridge and civil construction and, in particular, in the construction of high-speed temporary bridges.

Car-based pile drivers are known for driving test piles and nice dispersed volumes of pile work, consisting of a platform on a car chassis, a two-section mast, two telescopic struts with tilt hydraulic cylinders, a desiccant hydro-ram of the upper section of the mast, a two-drum windrower, tilting hydraulic cylinders, a descender of the upper section of the mast, a double-drum, and tilting hydraulic cylinders, tilting of the upper section of the mast, double-drum, and tilting hydraulic cylinders, tilting of the upper section of the mast, double-drum, and tilting cylinders, tilting of the upper section of the mast, double-drum, and tilting hydraulic cylinders, tilting of the upper section of the mast, two-drum winding, tilting hydraulic cylinders, lowering of the upper section of the mast, double-drum, and tilting cylinders, tilting hydraulic head Cl hydraulic outriggers

The disadvantages of these pile drivers are the large mass of the base, low productivity when driving piles of multi-sided pile fields with close proximity of rows of piles due to the frontal (rear) hinge of the mast, relatively large

cost of copra with actually low coefficient of use during the year and inefficiency of their use

. for driving piles on water. ,

Also known are pile-driving machines for pile driving, including a base machine, a platform with pneumatic scooters and a mast with a diesel-1 hammer fixed to it, with a diesel-hammer, a winch, and power shafts.

These copra are inefficient when driving in multi-pile fields, they do not have self-propelledness in the working position, in addition to the frame and drawbar of the trailer,

15 a design that complicates them; There is no possibility of using piles for working on water.

The purpose of the invention is to increase productivity due to side hinge.

This goal is achieved by the fact that in a pile-driven pile, including a platform with pneumatic wheels and a mast with a diesel-solo, a winch, power hydraulic cylinders hinged on it, the platform is equipped with cantilever beams with turn hydraulic cylinders and latches, which are hinged on one of its axles with hydraulic cylinders and latches, and pneumatic cylinders. connecting elements in the form of a fork bracket and mounted on the ends of the cantilever beams. The length of the cantilever beams, as well as the dimensions of the platform, are chosen so that in working position the driver has the exacting stability. The distance between the axles of the pneumatic wheels in the transport position is taken so that the slopes provide the minimum necessary clearance. FIG. 1 shows a pile Konejj in the transport position, side view; in fig. 2 - the same, transport position, top view; Fig, 3 - the same, in the working position, top view. The pile driver has a platform 1, a guide mast 2, telescopic struts 3, a hoisting winch 4, a slider 5 of a T-section, a hydraulic cylinder for extending and lowering the guide mast 6, a pyremode 7. Platform 1 is equipped with cantilever beams 8, supporting axles 9 flanges 10, hydraulic motors with gearboxes 11 and chain drives 12, turning levers 13 with hydraulic shafts 14, outriggers with hydraulic shafts 15, folding bracket - pad 16. In form 1 boards, rectangular cuts are made, covered with mudguards, 17 Two cantilever beams with one Copra sides have horizontal flanges 18 with bolt holes 19 at the ends, and two others on the other side of the copra have cutouts 2O at the ends, which are locked with inserts 21. In the transport position, each cantilever beam 8 is fixed by a hinge 22 and a lock 23, and working - the same hinge and latch 24. The supporting axles are suspended from the springs 25, which are hinged to the brackets 26 of the platform 1. The welded joint of the thorium axis 9c with flanges 10 is reinforced with welded stiffeners 27. The flanges 10 themselves have holes 28 for bolts. The pneumatic wheels 7 are equipped with fork brackets 29 with welded vertical flanges 3O in which holes corresponding to 50 .4 versts and 26 holes are drilled. In the transport position, the flanges 10 and ZO are connected with bolts 31. Horizontal flanges are welded to the two fork brackets 29 on one side of the pile head. 32, corresponding to the dimensions and openings of the flanges 18. In their working position, these flanges are interconnected by bolts. The two other fork brackets 29 have threaded vertical axes 33, nuts with locknuts 34, and also four-sided lugs 35. Slide 5 with a tee-section, used for mounting the mast, is movably mounted in the guides on the side 1 of the platform. The guide mast 2 in the head part is equipped with an I-beam bracket, to which Tori is welded a bearing flange and coupling pin, similar in design to the coupling of semi-trailers. Below, it is hinged 3-fold to the teeter of the T-section with a 5-loop hinge. In the transport position, the guide mast 2 is connected to the coupling device of a saddle car — a gacha by means of a coupling pin. Loop hinge at the same time locked pair of plates. If necessary, a power station can be installed on the platform to drive the hydraulic pump (not shown). Diesel-hammer 36 is placed on guide mast 2 in such a way as to ensure sufficient rear loading of my vehicle - T5P acha. From the transport position to the working pile one is transferred as follows. The outriggers 15 rest on the ground, the mudguard covers 17. open, and the pile driver is raised to unload the wheels. The cantilever beams 10 are swiveled 180 relative to the hinges 22 and connected to the fork brackets 29 on one side of the rider with flanges, and on the other with notches, vertical axes 34 and nuts with locknuts 35 (inserts 21 are removed beforehand). set). The vertical flanges 10 and ZO are disconnected from each other, the cantilevers 8 are rotated with pneumatic wheels 7 by 90 ° relative to the hinges 22 and secured with clamps 24, Chains 12 are put on sprockets and the turn levers 13 are connected to the tips 35. the driver is lifted and rests on the pneumatic tires 7, after which the coupling pin is disconnected from the saddle hitch of the vehicle. The pad of the bracket-platform 16 is removed and the guide mast 2, together with the telescopic struts 3, is raised to an inclined position using the hydraulic ram of extending and lowering the guide mast 6 until it is possible to fix the struts 3 to the ends of the cantilever beams 8. Loop the hinge is released from paired linings. (In Fig. 3, dotted lines indicate another possible attachment of the telescopic struts 3), The hydraulic cylinder extending and lowering the guide mast 6 is disconnected from the guide mast 2 and connected to the slider 5 of the teeter section, and the guide mast 2 is transferred to. vertical or any inclined position using telescopic struts 3 with hydraulic cylinders. The conversion from work to transport is carried out in reverse order. Diesel hammer 36 is constantly on the guide mast 2. The pile driver, in the working position, clogs the piles, moving parallel to the driven row of piles, since the guide mast 2 is located to the side of the direction of movement of the pile driver. The described pile driver, thanks to the above-mentioned structural differences, provides a reduction in the cost of operation and transportation compared to truck-based equipment and tractors and a reduction in weight. When driving in hzvaynyh fields Koper gives povieyen performance compared to the pile equipment on the basis of cars and uniaxial trailers, maintaining the same mobility and performance on the distributed objects with a small number of piles. In addition, the motor vehicle's motor resource saving is achieved with the possibility of using it for another purpose, both during piling works and during storage of a pile driver.
