Abstract

The invention relates to mine construction and may find application in the deepening of vertical shafts of mines. The goal is to increase the dismantling efficiency of the device by reducing the time to remove the elastically compliant material. The safety device contains shelves 1 and a shock-absorbing element 2 placed above it, which is made in the form of a ring 3 with intertwined strings 4 fastened on it, an elastically flexible material (UPM) 5 and a shield 6 covering the UPM 5 surface. In the UPM 5 array there is a metal a cylinder mounted vertically on shelf 1. In the upper part of UPM 5 between the end surface and shield 6 there is an annular shock absorber 11. Under the shelf 1 a diffuser 12 is fixed coaxially with the cavity of the cylinder (C) 10. The removable vessel strikes the strings 4, which bend, putting pressure on the shield 6. The shield 6 compresses the shock absorber 11 and causes the seal of UPM 5. When disassembling, the strings 4 are first removed, and then the shield 6, allowing access inside C 10. Cut out part of the shelf 1 located between the base C 10 and the base of the diffuser 12. In the lateral surface of the C 10, exhaust ports 14 are formed. The removal of the MFC 5, for example, rubble and slag, is carried out by hydraulic washing. Transport UPM 5 through the openings 14 and the diffuser 12 through the pipeline 13. 2 Il.

The diffuser 12 is fixed coaxially with the cavity of the cylinder (C) 10. When an emergency cable breaks, the falling lifting vessel strikes the A strings, which break down, exerting pressure on the shield 6. strings a and then shield 6 providing access

inside C 10 "Cut out part of the shelf 1 located between the base C 10 and the base of the diffuser 12. In the side surface C 10, exhaust openings 14 are formed. The removal of UF 5, for example rubble and slag, is carried out with a hydraulic washer. Transport UPM 5 through the openings 14 and the diffuser 12 through the pipeline 13. 2 or about

The invention relates to mine construction and can be used in the deepening of vertical shafts t

The aim of the invention is to increase the efficiency of dismantling the device by reducing the time to remove the elastically compatible material.

FIG. 1 shows the proposed device, general view, section; in fig. 2 - the same, top view.

The safety device contains shelves 1, a shock-absorbing element 2 arranged above it, made in the form of a ring 3 with intertwined strings 4 fastened on it, an elastically flexible material 5 located in the gap between the regiment 1 and strings 4, and also a shield placed close to the strings 4 6, covering the surface of the elastically compliant material 5. The strings 4 are fastened to the ring 3 by means of a 7 ° wire mount. The ring 3 is fixed in the lining of the trunk 8 with anchor bolts 9..

A metal cylinder 10 is installed in the array of elastically compliant material 5, in the upper part of which between the end surface of the cylinder and shield 6 there is an annular shock absorber 11, for example, in the form of a rubber inflatable balloon. The lower base of the cavity of the cylinder 10 is attached to the shelf 1. Under the shelf 1 is fixed diffuser I2 coaxially with the cavity of the cylinder 10.

The device works as follows.

In the event of an emergency break of the rope, the falling lifting vessel strikes the strings 4 of the damping device interwoven. Under the impact of the impact, the strings 4 bend, exerting pressure on the shield 6, which

in turn, it compresses the shock absorber Pi causes a seal of the elastic material 5 located on the shelf 1.

Shelf 1 has a stiffness sufficient to provide a seal for the elastically compliant material 5,

When compacting the elastomer material 5, the shield 6 is affected by the reaction distributed over the entire area.

backfilling, directed in the direction opposite to the fall of the lifting vessel. Having passed through shield 6 to strings 4, this reaction reduces their deflection to an acceptable value. The strings 4 are flexed and the elastoblastic material 5 is compacted until the lifting vessel stops.

After completion of the dredging of the trunk, in order to ensure the passage of the stands (skips) into the deep part, it is necessary to disassemble the safety device.

The disassembly is performed as follows.

Originally dismantled strings 4, at the same time to the diffuser 12

fasten the pipes 13. Then the shield 6 is dismantled, providing access to the inside of the cylinder 10. For example, gas-electric welding of a part of the shelf 1 located between the base of the cylinder 10 and the base of the diffuser 12 is cut. openings are located directly above regiment 1. The removal of an elastically compliant material 5, such as rubble or slag, is carried out with a water-wash, while the material 5 is transported through the openings 14 and the diffuser 12 via pipeline 13.
