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 a device for preventing side slipping of a support base. The device comprises a bearing block (1), an anti-drilling bottom baffle (2) and a guiding plate (3). The guiding plate (3) comprises a first fixing plate (301) and a cutting part (302). A fixing hole (303) is formed in the first fixing plate (301), and the distance between the fixing hole (303) and the bottommost end of the cutting part (302) is H+220 mm, wherein H is the thickness of the forepoling base, and the unit of H is millimeter; and the guiding plate (3) stretches deep into a soft bottom plate to achieve the sliding prevention and side moving prevention effects of a forepoling. The structure is practical, simple and reliable, and coal mining efficiency and safety production of a coal mine are improved.

Description

technical field [0001] The invention relates to the field of advanced support for coal mine roadways, in particular to a device and a use method for preventing the sideslip of a support base. 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 support hydraulic supports m...
