Description

The invention relates to mechanical engineering and can be used in various fields of national economy, for example, in construction, in the construction of foundations, in laying roads, in works when laying trenches, in dismantling old buildings, punching holes in walls, etc.

The purpose of the invention is the expansion of functionality by providing multi-mode operation,

To this end, it is equipped with a holder for the shock organ, mounted on the free end of the boom.

The installation is equipped with a handle placed on the platform with a guide and a hydraulic cylinder for moving it, in the upper part of which a tool holder is fixed, and the rod of the hydraulic cylinder for the handle is mounted with the possibility of moving along its guide.

The shaft of the handle hydraulic cylinder is spring-loaded along its guide.

In FIG. 1 shows the installation, front view; in FIG. 2 is an embodiment of installing a movable support in rails; in FIG. 3 - installation with a tilted platform, view A; in FIG. 4 is a diagram comparing installation options for a movable support in rails; Fig. 5 shows a boom control variant; in FIG. 6 is a fragment of an installation with a handle; in FIG. 7 - an option for installing a percussion instrument, view along arrow B; In FIG. 8 is an embodiment of installing a movable support on a handle.

The installation consists of a platform 1 (see Fig. 1), on which a boom 3 is mounted using a hinge 2, which may have a lifting mechanism 4. The hydraulic cylinder 5 connects the boom 3 to the platform 1. The holder 6 of the percussion organ 7 is adjacent to the boom 3.

To expand the service area, the platform 1 can be mounted by means of a hinge 8 on the base 9, and the latter on the axis 10c by turning from the hydraulic cylinder 11 mounted on the vehicle 12. The hydraulic cylinder 13 is connected to the movable support 14 mounted in the guides 15.

The guides 15 are mounted hingedly driven by a hydraulic cylinder 16.

The guides of the movable support 14 can be mounted directly on the boom 3. In FIG. 5 they are shown pos. 17. The hydraulic cylinder for moving the support 14 is shown in pos. 18, and the boom control cylinder pos. nineteen.

The handle 20 can be installed in conjunction with the boom 3 and has a hydraulic cylinder 21 for moving it and a tool 22 fixed with a holder 23 made, for example, in the form of plates 24 adjacent to the boom by a hinge 25 and connected to the handle by a hydraulic cylinder 26. The rod of the hydraulic cylinder 21 has a movable support 27 in the guides 28 and can be limited in movement by the spring 29. The impact body 7 in this case can be made with a radius R of the impact surface for contact with the radius surface of the tool 22, which is at a distance from the axis of the hinge 25 of (b) (see. Fig. b), which is equal to the radius R,

In the case of a hinged installation of the platform 1 on the base 9, it is connected by a hydraulic cylinder 30.

Installation works as follows.

By successive activation of the hydraulic cylinders 5 and 13 or 18 and 19, and in the presence of 16, the boom 3 is diverted from the object. Then, simultaneously turning on the indicated hydraulic cylinders, an impact is made on the object by the impact organ 7. By controlling the operation of these hydraulic cylinders, the acceleration of the impact organ can be changed and thereby the impact force. For example, by using the hydraulic cylinder 16, the guides 15 with the movable support 14 relative to the axis 2 of the boom 3 are approaching or removing. The closer the support 14 is movable in this case to the axis 2, the greater the acceleration. The diagram (see Fig. 4) shows the dependence of the angle of rotation of the boom 2 on the position of the movable support I and I. The position of the support 14 I and I refers to the stroke of the hydraulic cylinder 5, respectively (a) and (b), i.e. the closer the support 14 is movable to the axis 2 of the boom 3, the greater the acceleration of the lowered impact body 7, and therefore the impact force,

When the above-mentioned hydraulic cylinders are connected in series in the lowering mode using the lifting mechanism 4, loading and unloading operations can be performed.

With the hydraulic cylinders 11 and 30, the boom is positioned in the plane necessary for a better impact.

With handle 20, tool 22

the hydraulic cylinder 21 is connected to the object and

the hydraulic cylinder 26 is installed under

necessary angle. Hydraulic rod

21 into it. time is at point (g) of FIG. 6.

Then the rod of the hydraulic cylinder 21 is translated into

position (e), resting the tool 22 in the object. During the impact on the instrument by the impact organ 7, the distance between points (d) and (e) guarantees the operation of the hydraulic cylinder 21 without impact loads.

This unit design is versatile and multi-mode. By including two or three hydraulic cylinders in simultaneous operation, it is possible to force the shock organ to move with acceleration greater than the acceleration of the freely falling body (, 8) and thereby obtain a greater impact force with a smaller mass of the shock organ.

The presence of a handle with a percussion instrument holder allows for work underwater; in cramped conditions and most precisely.

Adjusting the position of the percussion instrument allows you to adjust the direction of the percussion. In FIG. 6, the letter (G) indicates the arrow in the direction of which the handle 20 moves at the moment of impact, and the corrected direction of impact is indicated by the letter (B).

This design allows the driving of piles, both straight and curved.
