Usage: in construction techno-NIKR and when extracting various long-length constructions from the ground. SUMMARY OF THE INVENTION: A device comprising a percussion assembly with a device for fastening it to the upper torda of a window made in a removable structure is provided with transverse strips interconnected by means of drafts. In this case, the impact unit with a device for its attachment is placed under one of the strips attached to the recoverable structure or a spacer unit installed between the base of the impact unit and the lower end of the window and made in the form of a screw pair or a pneumocylinder. The attachment device is made of a hub of a sleeve with a slit, the sides of which form an acute angle with the tip facing the side of the shock hole. The window of the removable structure is made with an offset or at an angle of the longitudinal axis about 9 or more.

Description

The invention relates to construction equipment and can be used in the extraction of various lengthy structural elements (channels, dowel, I-beams, etc.) from the ground.

In the technique for extracting lengthy structural elements from the soil, various static tools are widely used. In the known technical solutions, the extraction of structural elements from the soil consists in the application of a vertical force to the upper part of the extracted element

However, the force is applied periodically, so the process is inefficient. This is due to the need to change the place where the vertical force is applied, like the various rods, which transmit the force from the actuator to the extracted structural element, shorter than the extracted structural element.

A disadvantage of the known static method of extracting lengthy elements from the soil is also the difficulty of achieving great effort, which requires powerful metal-intensive and large-sized equipment.

The device contains a shock assembly 1 with a device for fastening it in the form of strips 2 and 3 interconnected by means of a rod (attached to the upper end of a window made about 5 of the extractable structure 5, the spacer v-bc is made in the form of a screw pair 6 or pneumocytosis 7.

A device for realizing the extraction of long metal elements-30 tov works as follows.

When compressed air is applied to the impact unit 1 "(Fig. 1), pulses are generated that act on the upper

RA directly and removes Ele S-ICMT 5 from the soil,

The expansion node compensates for the recoil force that occurs during operation, and ensures contact of the impact node with element 5.

FIG. an embodiment of the device is shown, in which a sleeve 8 with a slit 9, whose sides are inclined, i.e. form an acute angle. When the angle is smaller than the friction angle of the metal o metapp (less (°), a self-enclosing effect occurs, i.e., without the distance knot, it is possible to ensure constant contact of the impact knot k with the upper mountaineer of the window k of the element.

FIG. Figure 8 shows the device, which is attached to the extracted element by means of slats and in an extractable structure, with an autogen, an opening is cut into which it mounts the strap. Another plank 3 is installed below the impact knot of pa 1, and after that, the elements of the system are tightened with k.

The latter design is more resilient, but more reliable in operation, as the wound i connects the shock junction even at the initial time (during installation).

The application of the proposed method and device allows the removal of the length of the window A in the extractable element, some metallic structures. The preliminary impact unit 1 of the device, such as Ivellers, I-beams, from the soil, is cast in the center of the window k and spacer in cramped conditions.

In addition, due to the simultaneous impact of a shock load in 40 vertical and horizontal directions, as well as bending and rotating chongs, the efficiency is increased.

knot, made in the form of helical paraslinnvara 6 or pkevmotsilndrats.

The pulses produced by the impact unit 1 are directed upwards in the direction of extracting a lengthy element from the soil. Due to the placement of window A in the wall of the element at an angle to the longitudinal axis (Fig. D) with an offset relative to 1 the longitudinal axis of the extracted, long element Fig. 3) a horizontal component arises (in the first case) or a moment (in the second 50 case) that causes the extracted element to swing in the transverse direction.
