The drop unit RB 8 is made of a suspended cable 10 connected to the upper part of the mast 2 connected to its ends, and mounted on the upper part of the mast 2 hydraulic cylinders 12. Through the blocks 14, one of the branches 15 of the rope 10 is stockpiled on the hull and gatoka. On X 9 a guide reflector 16 of the rope 10 is fixed, arranged in the form of plates located above X 9 and directed away from it 17, connection interconnected with the formation of dihedral angle. The edge of the angle passes through the free end of X 9 and is located in a vertical plane passing through it with an inclination towards the latter. When lifting PO 8, X 9 reaches the loop part and, due to the reflector 16, deflects the rope 10 to the side, falling into the inter-branching space. By the hydraulic cylinder 12, the length of the rope 10 is shortened to the position of the loop part of the rope 10 at the level of dropping PO 8, Traverse 4 is lowered, X 9 abuts against the loop part of the rope 10 and the gripper 6 rotates, providing a reset PO 8. 3 sludge.

The invention relates to road and construction engineering, in particular to mechanisms for percussion / development of solid soils, including frozen.

The purpose of the invention is to increase the reliability of the device, performance and reduce labor costs for readjustment in the device of the working body actuation unit, depending on the physical and mechanical properties of the soil.

Figure 1 schematically shows the device, a general view; figure 2 is a view of And figure 1; on fig.Z - section BB in figure 1,

The device for the impact development of durable soils includes a base machine 1, a mast 2 mounted on it with a guide 3, on which the yoke 4 is movably mounted, on the axis 5 of which a hook hook 6 is attached, connected by means of a hitch pin 7 to the working body 8. Hook hook 6 configured with a shank 9 for engagement with a mounting stop located on the mast, for discharging the working device 8.

The drop unit of the working body 8 is made of a suspended rope 10 attached by its ends to the upper part of the mast 2, forming a loop-back part 11 of the mounting stop.

and from the hydraulic cylinders 12 installed on the top of the mast 2 with blocks 13 and 14 on the housing and the rod through which one of the 15 branches of the suspended rope 10 is stored. At the same time, the hook 9 of the hook hook 6 is equipped with a fixed reflector 16 of the suspended rope 10 fixed on it, made in the form located above the shank 9 and directed away from him plates 17, which are interconnected with the formation of a dihedral node, the edge of which passes through the free end of the shank 9 and is located in a vertical plane, the passage Through shank 9, inclined to the side of the latter.

The branch 18 of the rope 10 is fastened to the mast 2 with the help of the shock absorber. The traverse 4 is connected to the cable-block mechanism for its raising and lowering. On the mast 2 is fixed casing, reflecting from three sides branches 15 and 18 of the rope 10.

Device for the shock development of solid ground works as follows.

The base machine 1 combines the axis of the working body 8 with the required ground development site, after which the cable-block mechanism 20 of the yoke 4 together with the working body 8 rises from the lower position upwards.

When lifting, the shank 9 of the hook grip 6 reaches the loop part 11 of the rope 10 and, thanks to the reflector 16, deflects it to the side, after which the shank 9 falls into the inter-branching space of the branches 15 and 18.

By the hydraulic cylinder 12, the length of the rope 10 is shortened to the position when its loop part 11 is located at the level required for dropping at the appropriate necessary height of the working member 8. Thereafter, the cable-block mechanism of the yoke 4 is lowered. The tail 9 of the hook grip 6 rests on the loop part 11 of the rope 10. The hook grip 6 rotates on the axis 5, ensuring the discharge of the working body 8.

Hook grip 6 under the action of the weight of the shank 9 and the reflector 16 occupies its original position. The traverse 4 is lowered until the hook grip 6 interacts with the finger 7 of the operating member 8, and the lifting cycle of the drop of the working member 8 is repeated. To reduce the dynamic loads acting on the rope 10, the branch 18 is attached to the mast 2 via a shock absorber.

To prevent the rope 10 from swaying from vibration or wind, there is a protective casing protecting the branches 15 and 18 of the rope 10 from three sides. The reflector 16 serves as a plate 17 of the reflector 16.
