Definitions
- the present invention relates to a mobile device for driving into the ground, by percussion, of various objects and, in particular, of dowels intended for fixing posts or stakes.
- a device of the type comprising a carrying structure intended to support a pendulum element along which slides a mass whose movements are ensured by a cable connected to a drive device having an operating cycle in two time, namely:
- the mass can strike, directly or indirectly, the object that is desired push in and that has been previously arranged in line with the lower end of the pendulum element.
- a first problem results from the fact that as the element is pushed in, the point of impact of the mass moves downwards. Consequently, provision should be made for permanently adapting the travel of the mass and, consequently, its guidance, to the level of insertion of the object to be inserted. It should be noted in this regard that a possible solution to solve this problem may consist in using a pendular element of tubular shape whose inner surface is used for guiding the mass and to introduce initially, in the lower part of this tubular element, the object to be pushed in. Thus, during the insertion, the part of the object protruding outside the ground remains inside the tubular element and is guided, permanently, in the volume of passage of the mass.
- this solution has the drawback of limiting the shape of the objects to be inserted, to the dimensions of the interior volume of the pendulum element.
- it is subject to frequent jamming, by deformation of the objects to be inserted, inside the pendulum element, under the effect of shocks, in particular in the case of hard ground.
- the invention therefore firstly aims to eliminate these drawbacks. To this end, it offers a longitudinally extendable pendant element whose length adapts permanently to the height of the object during its insertion, and which ensures perfect continuity of the guiding of the mass which let this length be.
- this element pendulum comprises a tubular structure, longitudinally divided into two parts each having at least two guide surfaces of two opposite zones of the mass so as to be able to ensure alone the longitudinal guide of the mass, the guide surfaces of the one of the parts being offset angularly with respect to those of the other part, and means for connecting these two parts with free longitudinal sliding of one of the parts with respect to the other.
- the above pendulum element as well as said mass have a section in the form of a quadrilateral.
- each of the two parts constituting the tubular element comprises two parallel profiles in the form of a cor ⁇ nity, of concavity facing each other.
- the opposite internal faces of these two sections are spaced from each other by a length substantially equal to that of one side of said quadrilateral.
- each of these two parts are fixed to each other by their ends by means of two fixing devices, at least one of which consists of a tubular section of inner section in the form of a quadrilateral comprising internal walls which have two opposite angular regions on which are applied and fixed the external faces of said sections, and two angular guide regions.
- the assembly of the two parts of the pendulum element is then carried out so that the profiles of one of said parts pass through the tubular section of the other part and are guided by the angular guide regions of this tubular section. and vice versa.
- the pendulum element is connected, by its upper end, to the structure of the device by means of a mechanical gimbal connection integral with one of the above-mentioned parts so as to allow free swinging of the pendulum element in two perpendicular directions.
- the lower end of the tubular element may include means for longitudinally guiding a driving-in tool and for guiding dowels with a central sheath intended for fixing in the ground posts or stakes and a type similar to those described in patent application No. 78 11279 of April 10, 1978 and certificate of addition No. 79 09679 of April 10, 1979, for: “Anchor intended for fixing in the ground of posts or stakes and device for driving this pin ", deposited in the name of the Applicant, these guide means being provided so that the mass comes into impact at the end of the stroke the upper end of the driving tool.
- the mass can also comprise, fixed on its lower face, a pile-shaped part substantially coaxial with the pendulum element.
- This part may advantageously have a length slightly greater than that of said dowel so as to permanently produce, during the insertion of the dowel, a pilot hole.
- the lower end of the tubular element may comprise means allowing the head of the dowel head to be held in position, these means equipping the lower end of the part of the tubular element which is not located not connected to the aforesaid mechanical cardan link.
- Another problem which the invention aims to solve relates to the development of a kinematic chain intended for the drive of the mass and which is adapted to the pendulai ⁇ re element described above.

- the mass 19 which descends in free fall in the pendulum element is raised by a cable 20 which passes through the mechanical cardanic connection 21, so that it always remains in the longitudinal central axis of the pendulum element 18.
- the mechanical cardanic connection comprises first of all, as shown in FIG. 3, a yoke hinge 50 in the form of a U on the core of which are fixed two coaxial pins 51 extending in the longitudinal plane of symmetry of the yoke.

- the cable drive device 20 consists of at least one arm 60 rotatably mounted by one end on one of the two parallel beams 4, 5 of the structure 1 of the device and on which is rotatably mounted, at the other end, a pulley 61.
- This arm 60 is rotated from the gear motor 23 by a freewheel transmission system.
- the arm 60 is mounted idly on an axis 62 on which there is also rotatably mounted a second arm 63 driven in rotation by the gear motor group 23 by means of a chain transmission 64 and sprockets 65 ( figure 1).

- the driving in of these pegs can advantageously be carried out by means of a driving tool comprising a rigid elongated body 73 having at least, in its lower part, the shape of a false pile of slightly longer length. greater than that of the ankle and, at the upper end of this false pile, a shouldered portion 74 intended to transmit a driving force on the upper face of the ankles.
- the driving tool is incorporated into the mass 19 and consists - He* -
- the mass comes directly to bear on the upper face of the pins and the pendulum element 18 comprises, at its lower part, means for centering said pins.
- the driving tool comprises, in addition to the false pile 73 and the shouldered portion 74 for driving the pins 70, a rod 77 mounted axially sliding in a bearing 78 provided at the lower end of the pendulum element 18 and on the head of which the mass 19 comes.
- the head 80 of the rod 77 may have a rounded shape and the underside of the mass 19 may include a central recess 81 in which said rounded shape of the head 80 of the rod 77 can engage.
- This arrangement thus allows good centering of the rod 77 during the impact of the mass 19.
- means can be provided for securing the head 80 of the rod 77 to the mass 19, so as to facilitate the extraction of the driving tool, once the pin 70 is pressed.
- these fixing means consist of a key or a pin 80 ′ in the shape of a U engaging in a groove 82, 84 formed in the head 80 of the rod 77 and in the recess ent 81. This provision therefore allows the lifting of the bottom of the pendulum element.
- the pendant element 18 can be driven in any direction longitudinal and transverse, so as to locate at will its longitudinal axis at a precise point by adjusting the height at each support point on the ground of the structure by means of the cranks 12, 16. These height adjustments allow in particular:
- the device can comprise, for its traction, a winch 100 which is parallel to the axis of the wheels 8, 10, 19, 14 and suitably centered, so as to obtain an advance of the device in a precise direction. determined even in very steep or swampy areas.
- This winch can be equipped with a tachometer allowing the automatic calculation of the intervals between each sinking operation in the ground by the tool.
- the geared motor group 23 may consist of an internal combustion engine 101 with gearbox 102, possibly automatic, differential 103 and centrifugal clutch.
- one of the sides of the differential can be coupled to the aforesaid second arm 63 for lifting the mass, the other side being used to actuate the winch. It then suffices to block one of the sides of the differential for the other to be operational and to accelerate or slow down the engine to start the differential or stop everything.
- it may include safety grids surrounding the pendulum element 18 and fixed on the tubular sections 33, 38, so as to prevent any access to the voids which occurs when the pendulum element 18 develops.
- the device for holding the dowel 70 pressed in on the ground comprises a support piece 105 on the dowel on the ground, held by rods 106 slidably mounted on the pendulum element 18 and which can be blocked for example by means of clamping screws on the upper part 24 of the pendulum element 18.
