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...
