Abstract

The invention belongs to the field of coal mining supporting equipment, in particular to an anti-toppling safety type hydraulic support, comprising a bottom adjusting mechanism arranged on a support base, the bottom adjusting mechanism comprises rotating sleeves rotationally connected to the front end and the rear end of the support base, sliding sleeves are slidably connected into the rotating sleeves, inserting rods capable of stretching into the sliding sleeves on the next support base are slidably connected into the sliding sleeves, and a locking mechanism is connected between each rotating sleeve and the corresponding sliding sleeve. The problem that a hydraulic support is toppled due to the fact that a hydraulic support base sinks due to the fact that a working face bottom plate is loose can be solved.

Description

technical field [0001] The invention relates to the field of support equipment for coal mining, in particular to an anti-dumping safety hydraulic support. Background technique [0002] Hydraulic support is an important part of fully mechanized mining equipment in coal mines. It uses hydraulic pressure as power to realize movements such as lifting and moving forward. It can reliably and effectively support and control the roof of the working face, isolate the goaf, and prevent gangue from entering the mining face and Propelling conveyor; used in conjunction with coal mining machines to realize comprehensive mechanization of coal mining, solve the contradiction that roof management lags behind coal mining work in coal mining work, further improve and enhance the efficiency of coal mining and transportation equipment, and reduce the labor intensity of coal miners , to maximize the safety of coal miners. [0003] During the production process of fully mechanized mining working ...
