Problems solved by technology

[0003] The current fall arrester is mainly of mechanical structure, the structure is complex, and it is easy to have problems in the transmission process. Once a problem occurs, the fall arrester cannot work or the clamping force is not large enough, it will cause incalculable consequences; the lack of the main rope The active maintenance device does not fundamentally protect the main rope and prevent it from breaking

Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0030] Such as Figure 1-Figure 7 Shown, a kind of mining hoisting cage safety protection method described in the present invention, this method comprises the following steps:

[0031] S1, an elastic rubber airbag is installed at the bottom of the lifting cage channel, and water is flushed into the elastic rubber airbag;

[0032] S2, on the basis of S1, a safety protection rope is connected to the top of the lifting cage;

[0033] The hoisting cage adopted in this method comprises an outer guard 1, a cage 9a and a switch box 9b, and also includes a lifting mechanism 2, a first box body 3, a second box body 4, a hydraulic oil tank 5, a protection mechanism 6, a buffer mechanism 7, Maintenance mechanism 8, pressing plate 9 and fixed rod 9c, descri...

Abstract

The invention relates to the technical field of mining protection equipment, in particular to a safety protection method of a mining lifting cage. The safety protection method comprises the followingsteps that S1, an elastic rubber airbag is mounted at the bottom of a channel of the lifting cage, and the elastic rubber airbag is filled with water; and S2, a safety protection rope is connected tothe top of the lifting cage based on step S1. According to the safety protection method, the lifting cage drives a pressing plate to move through hydraulic oil, so that an auxiliary rope is clamped and limited to achieve rapid anti-falling protection; rubber heads are distributed on the surface of the pressing plate, so that the friction force is improved; and the pressing plate is of an inward concave arc-surface structure and thus can be attached to the auxiliary rope more closely, so that the protection effect is improved, and the clamping force is larger; and main ropes can be cleaned through brushes, so that the friction between the main ropes is reduced, aging of the main ropes is delayed, rusting of the main ropes is avoided, and breakage of the main rope is prevented fundamentally.

Description

technical field [0001] The invention relates to the technical field of mine protection equipment, in particular to a safety protection method for a mine lifting cage. Background technique [0002] The cage is an essential equipment for mine operations. It can lift ore, waste rock and lift personnel, materials and equipment. It can also be used as an air shaft, which can effectively improve mining efficiency. Then the cage only relies on ropes for lifting during the up and down movement. There is a danger of the rope being pulled off, and a fall arrest device is required. [0003] The current fall arrester is mainly of mechanical structure, the structure is complex, and it is easy to have problems in the transmission process. Once a problem occurs, the fall arrester cannot work or the clamping force is not large enough, it will cause incalculable consequences; the lack of the main rope The active maintenance device does not fundamentally protect the main rope and prevent it ...
