Description

The invention is intended for the destruction of reinforced concrete, concrete and other massifs and can be used in the reconstruction of enterprises, g in mining, road and hydraulic engineering construction.

The purpose of the invention is to increase the maintainability of the device by allowing the hydraulic cylinder to be disconnected without opening the hydraulic system.

Pa figs. 1 shows the device, a longitudinal section; in fig. 2 shows section A-A in FIG. 1.15

The hydraulic wedge device consists of a housing 1, a hydraulic cylinder 2, sliding cheeks 3, an expansion wedge 4.

The hydraulic cylinder 2 is installed- 20 flax inside the hollow body 1 with the possibility of longitudinal movement and contains a cup 5 with a bottom 6, a piston 7, an ejector 8 and a hydraulic distributor 9. With the body 1, a hydraulic 25 indr is connected by means of a detachable locking ring 10, which interacts with Cylinder 8 bollard 2. A spacer wedge 4 is pivotally attached to the bottom 6 of cylinder 2 on the outer side of the butt-opposite end, and interacts with the working surfaces of the sliding cheeks 3. The sliding cheeks 3 are mounted with support arms in windows 11 boxes 1. The hydraulic distributor 9 is mounted on the rod 8, in which the channels 12 are made for supplying the working fluid to the cylinder cavity 2. The detachable retaining ring 10 can be represented as half-rings 13, the inlet g (them in the grooves 14 made on the rod 8 and case 1, and covered by an elastic ring 15.

The device works as follows.

Sliding pitch 3 devices are installed in the hole drilled in the array. The spacer wedge 4, when installed in the hole, is located in its extreme upper position, the hydraulic cylinder is in the compressed position. After that, in the piston strips 1 ′ of the cylinder 2 through the hydraulic gates 9 and the channels 12, the working fluid is supplied under pressure. As a result, the cup 5 with the bottom 6 of the hydraulic cylinder 2 is moved to the sling

housing 1 and pushes a spacer wedge 4, which interacts with the sliding cheeks 3 and moves them away from the longitudinal axis of the device. Upon further movement of the spacer wedge 4, the sliding cheeks 3 abut against the wall of the hole and, applying diametrically directed forces to them, destroy the mass. When the working fluid is supplied into the rod cavity of the hydraulic cylinder 2, the cup 5 with the bottom 6 makes a movement in the opposite direction and draws the spacer wedge 4 into the device, releasing the sliding cheeks 3. The axial forces developed in the rod from the displacement wedge 4 are transmitted to the body through the detachable locking ring 10. On the housing 1, a viewing hole can be made, allowing you to visually observe the movement of the glass 5 of the hydraulic cylinder 2, and if there is a measuring ruler on the glass 5 lzani the working stroke of the expansion wedge 4 and, respectively, sliding tsek 2,

The device can be easily represented by two units that are comfortable and easy to carry: a hydraulic cylinder assembled with a spacer wedge and a body with sliding cheeks. Repair of this device in the quarry is carried out by the knotted method. A faulty hydraulic cylinder with an expansion wedge and a hydraulic distributor is taken out of the body and a new one is installed instead.

Claims (1)

Claims of the invention A hydraulic wedge device comprising a housing with windows in which the supporting arms of the sliding cheeks are installed, a hydraulic cylinder with a piston with a rod and a hydraulic distributor, aligned with the housing and a hydraulic cylinder and a spacer wedge installed between the sliding cheeks, characterized in that , in order to increase the maintainability of the device by providing the possibility of disconnecting the hydraulic cylinder without opening the hydraulic system, the device is equipped with a retaining ring, rigidly connecting the case with the hydraulic cylinder rod with the ability to disconnect them, while the rod of the hydrocine wedge, the hydraulic cylinder is connected to the expansion wedge by the outer face of the oppository, and is located in the offset, and the hydraulic distributor is mounted on the rod in which the fluid supply channels are made.
