Problems solved by technology

However, many of these advanced support supports need to be provided with pull frame anchor points, and the process of setting anchor points is cumbersome and inefficient, and it is impossible to realize fast and safe advance hydraulic support support; Moving the frame can cause movement deflection and difficulty in moving the frame
It greatly affects the coal mining efficiency and coal mine safety production work

Abstract

The invention discloses an apparatus for accurately positioning a hydraulic fore-support moving route. The apparatus comprises a load bearing block (1), a bottom-drilling-preventive baffle (2) and a guide plate (3), wherein the guide plate (3) comprises a first fixed plate (301) and a cutting part (302) connected to the bottom of the first fixed plate (301), a fixed hole (303) is formed in the first fixed plate (301), the distance between the fixed hole (303) and the bottommost end of the cutting part (302) is H+280 mm, H is the thickness of a fore-support base, and the unit of H is mm. The apparatus is safe, practical, simple and reliable, and is capable of improving the coal mining efficiency and the safety production work of a coal mine.

Description

technical field [0001] The invention relates to the field of advanced support for coal mine roadways, in particular to a device and method for accurately positioning the moving path of an advanced hydraulic support. Background technique [0002] my country's "Coal Mine Safety Regulations" clearly stipulates that the range of advance support along the trench in the coal mining face should not be less than 20m. In traditional mining areas, single hydraulic props are generally used for advance support along the trough of fully mechanized mining face. The pattern matches, and this support method has disadvantages such as low support strength, high labor intensity for workers, and slow support speed. In order to solve these problems, the Taiyuan Branch of the General Institute of Coal Science and Technology, Zhengzhou Coal Mining Machinery Group Co., Ltd. and other equipment manufacturers have developed different types of advanced support hydraulic supports. These advanced supp...
