Quick hoisting device for fully-mechanized coal mining bracket

Abstract

The invention discloses a quick hoisting device for a fully-mechanized coal mining bracket. The quick hoisting device comprises three anchor cables (1), a steel triangular frame (3) and a rotatable hoisting hook, wherein the three anchor cables (1) are punched into stable positions on a top plate (2) at the end socket of a fully-mechanized coal mining working surface two by two at equal intervals, and meanwhile the peak of the steel triangular frame (3) is fixed; the rotatable hoisting hook consists of a pulley (4), a rotating disk (5), a hoisting hook body (6) and a steel cable (7); the upper end of the hoisting hook body (6) is connected with the center of the steel triangular frame (3) through the rotating disk (5) and the pulley (4), and the lower end of the hoisting hook body (6) hooks the steel cable (7); the other end of the steel cable (7) is connected to a hydraulic bracket (8). The quick hoisting device is not limited by the space and can quickly hoist the bracket, so that quick bracket loading can be realized; meanwhile, the bracket hoisting process is simplified, and the investment cost is greatly lowered.

Description

technical field [0001] The invention relates to a coal mining support, in particular to a quick hoisting device for a fully mechanized mining support. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face, and the mine pressure of the mining face acts on the hydraulic support in the form of external load. At present, in the coal mining technology, the most difficult part of the hydraulic support relocation of the working face is the lifting and loading of the hydraulic support. Generally, coal mines use special hydraulic cranes or lifting equipment, but this method not only has high equipment costs, but also has labor hours. Many, the hoisting process is cumbersome and other disadvantages. At the same time, due to the small space under the mine, the special hydraulic crane or lifting equipment needs to occupy a large space, resulting in inconvenient construction operations and difficult support removal, w...

At present, in the coal mining technology, the most difficult part of the hydraulic support relocation of the working face is the lifting and loading of the hydraulic support. Generally, coal mines use special hydraulic cranes or lifting equipment, but this method not only has high equipment costs, but also has labor hours. Many, the hoisting process is cumbersome and other disadvantages. At the same time, due to the small space under the mine, special hydraulic cranes or lifting equipment need to occupy a large space, resulting in inconvenient construction operations and difficult relocation of supports, which affects work progress.
