Abstract

The invention relates to a lifting and transport equipment, in particular to lifting vessels and counterweights, and is intended to guide their movement in the conductors of rigid reinforcement of vertical shafts. The purpose of the invention is to increase operational reliability and efficiency by increasing the service life of liners. The guide shoe of a mine lifting vessel comprises a housing 1 in which interchangeable liners 2, 3 and fastening elements are housed. The frontal and lateral liners are made in the form of solid rectilinear bars fixed with clamping plates 4, 5 with the possibility of moving the inserts in the direction of the working surfaces of the conductor. Compensating spacers 8 are placed between the bases of the liners and the housing. In the housing there are slots in which lateral liners are installed. One of the side surfaces of each liner and the contacting surface of the body or pressure plate is made with a slope. 3 il.

The invention relates to a lifting and transport equipment, in particular to lifting vessels and counterweights, and is intended to guide their movement in the conductors of rigid reinforcement of vertical shafts.

The purpose of the invention is to increase operational reliability and efficiency by increasing the service life of liners.

FIG. 1 shows a guide.

3 is placed in the housing nest and clamped with overlays 5 with the help of bolts 7.

The guide shoe operates as follows.

In the course of the interaction of the guide shoe of the moving lifting vessel with the conductors, the liners are mechanically worn, with the result that the gaps between the working surfaces of the liners and the conductor increase.

from the side; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2

the gaps are reduced to their original values by moving the liner in the direction of the conductor by the amount of the guide shoe of the mine hoist. To move the side liner the vessel contains U-shaped cast 3, bolts 7 are removed, clamping body I, frontal 2 and side 3 interchangeable supplemental pad 5 are removed, the liner is moved and a dip, pressure pads 4 and 5 are correspondingly formed clearance between its base

8, located between the bases of the inlet and the restoration of the original breathing gap and the casing between the frontal liner and the conductor,

remove the bolts 6, remove the cover 4 together with the liner, install the gasket 8, put the insert together with the cover in place and fix them with the bolts. With the maximum allowable wear of liners, determined by the reliability of fastening, they are changed with new ones in the order described above and with the removal of all compensating pads.

Inserts 2 and 3 are made in the form of solid rectilinear bars, which allows them to be made by casting or powder metallurgy from known materials with wear-resistant and anti-friction properties. The liner 2, located on the base of the case, is fixed with the help of bolts with a figured pressure pad 4, covering the insert with sin sides. In order to unload the bolts 6 from shock loads, when the liner hits the ledge of the conductor junction on the body of the shoe, there are protrusions 9 limiting the plates to the liners along the shoe. The side inserts 3 are located 35 in the housing slots and pressed from above by the pads 5 with the help of bolts 7. To ensure that the inserts are securely fastened and prevent them from spontaneously moving in the direction of the conductor due to vibrations while loosening the bolts, inaccurate manufacturing, etc. One of the side faces of each liner and the surface of the body or pressure plate that is associated with it is made with
