Fully-mechanized mining support lowering device and lowering method

Abstract

The invention discloses a fully-mechanized coal mining support down-pass device and down-pass method, so that a fully-mechanized coal mining support is stably and safety fed downwards. According to the fully-mechanized coal mining support down-pass device, two locating ropes and a locating ring are used for fixedly binding a fully-mechanized coal mining support on a tackle horizontally, and then the fully-mechanized coal mining support is fed downwards through a winch. In the down-pass process, the fully-mechanized coal mining support is always perpendicular to slide rails and horizontally arranged. The fully-mechanized coal mining support can be in place in one time without direction adjustment, and the whole process is safe and reliable.

Description

technical field [0001] The invention relates to a fully-mechanized mining support lowering device and a lowering method applied in the field of coal mining. Background technique [0002] The fully mechanized mining support is a support commonly used in the coal mining field to be installed on the working face. When this support is installed, it is generally vertical down. The fully-mechanized mining support is connected with the traction rope on the winch, the bottom of the fully-mechanized mining support is connected with the pulley, and a slide rail is arranged below the pulley, and the pulley and the slide rail are slidably matched. The length direction of the fully-mechanized mining support is parallel to the length direction of the slide rail. This decentralization method has a relatively simple structure, but has the following disadvantages: [0003] 1. When reaching the installation position of the cutting eye on the working face, it needs to be adjusted (two winche...

AI Technical Summary

Problems solved by technology

[0003] 1. When reaching the installation position of the cutting eye on the working face, the direction needs to be adjusted (two winches need to be used for multiple times to reverse the adjustment), and finally the length direction of the fully mechanized mining support is adjusted to be perpendicular to the slide rail, which has potential safety hazards

[0004] 2. There is only one connection point between the fully-mechanized mining support and the drawworks traction rope. When lowering the working face with a large inclination angle, the center and balance of the fully-mechanized mining support are not easy to grasp, which may easily cause the support to tilt during the lowering process, or even between the pulley and the slide rail. Stuck, which leads to the inability to continue the decentralization

[0005] 3. The pulley and the slide rail are in point contact and the force is large, which may easily cause the slide rail to break, which in turn will cause safety accidents such as the pulley falling off the track, rolling over and overturning the frame.
