Description

one

The invention relates to mining elevators, in particular to mine elevators-cabins or cages, and can advantageously be used for lifting or lowering materials along vertical mine workings, such as pits or boreholes with a circular cross-section.

Basically auth. St. No. 595243 describes a device for mechanized lifting of minerals, containing skip and rolikoopor made of road wheels, hinged on the skin 1.

However, the known device does not provide convenience when unloading materials from the vessel into the mine yard in wells and pits with a circular cross section. This is due to the fact that during the descent or ascent, the vessel doors may deviate from the entrance to the mine yard caused by the rotation of the vessel around the longitudinal axis under the effect of the unwinding effort of the lifting rope, since it does not have devices that prevent the vessel from turning around the longitudinal axis. As a result, vessel doors may be located on the opposite side from the entrance to the mine yard, and therefore unloading of materials will be impractical.

The purpose of the invention is to improve ease of operation.

For this, the device is equipped with a skip clamping mechanism against the walls of the shaft 5 of the barrel, which contain support frames mounted on the side walls of the skip with jacks with rigid rods attached to them, at the ends of which the spring-loaded

10 levers with roller-bearings interacting with the walls of the shaft shaft, with the axis of rotation of at least two roller-bearings parallel to the direction of movement of the skip.

15 In addition, one of the support frames is folding.

FIG. 1 shows a general view of the device at the time of movement along the shaft; in fig. 2 - the same, at the time of unloading the material at the required level of the barrel; in fig. 3 - the same, top view.

The device consists of a lifting skip 1, made in the form of a cylindrical or other shape, to which are attached

25 by means of screw jacks 2 support frames 3. Levers 5 are hingedly attached to support frames 3 by means of t g 4. Roller supports 6 made of road wheels are mounted on the levers. For

30 to ensure uniform rolling of the irregularities of the barrel 7, the rollers 6 are spring-loaded. From the outer side of the vessel 1, the walls of the vessel 1 are fixed by means of screw jacks 8 of the roller supports 9, whose axes of rotation 10 are parallel to the direction of movement of the skip or the central longitudinal axis of the barrel. One of the walls I is made folding by means of a hinge 12 installed at the bottom of skip 1. Skip 1 is equipped with a winch 13 for lifting or lowering the cable 11 by means of cable 14 to reliably fix the vessel when loading or unloading materials into horizontal mine workings adjacent to the shaft 7 15 of the mine yard, an emphasis 16 is provided, made in the form of a recess in the shape of the roller-support 9 entering it fixed on the folding wall 11. The device with the aid of the suspension 17, the trailer 18 and the rope 19 is connected with the g lifting gear 20. Skip has a door installed in front of the folding wall I.

The device works as follows.

In the initial transport position, the screw jacks 2 are pushed, i.e. pressed against the walls of the shaft shaft, and screw jacks 8 are pushed in, the folding wall 11 is raised to the vertical position by means of a winch and fixed. In this position, the device is prepared for launching into trunk 7. When the device is lowered, its rotation around the axis is possible due to the unwinding effort of the hoisting rope 19. As a result, when the device approaches the required horizon, the folding wall II may not coincide with the receiving yard of the mine yard, which will not allow provide unloading or loading of materials. In order to align the folding wall 11c with the receiving yard of the mine yard, screw jacks 2 are pushed in and screw jacks 8 are pushed out. This ensures that roller 5 is removed from contact with the walls of the barrel 7 and adjoined to the walls of the barrel 7 roller 9. After that, a manual drive (not shown) rotate the roller supports 9, which ensures the rotation of the device around its longitudinal axis to the required angle. Then the folding wall 11 is lowered and fixed in the support 16. The preparation of the device for lifting is carried out in the reverse order. This device allows you to increase

the performance and operational reliability of the tunneling works by eliminating the vessel swaying in the well.
