Abstract

The invention relates to the technical field of hydraulic supports, in particular to a Hydraulic support electrohydraulic control device. The hydraulic support electrohydraulic control device comprises a mounting box for mounting of a controller. First connecting rods are hinged to the two sides of the mounting box, second connecting rods are hinged to the free ends of the first connecting rods, and the second connecting rods are hinged to a top beam of a support. The problems that in the prior art, the controller is fixed, and operation of a worker is not convenient are solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to an electro-hydraulic control device for hydraulic supports. 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 Advance the conveyor. The labor intensity of coal miners is reduced, and the life safety of coal miners is guaranteed to the greatest extent. [0003] The electro-hydraulic controller is an indispensable part of the work of the hydraulic support. The existing controller is mostly installed at the bottom of the top beam of the hydraulic support, and its position cannot be adjusted. When the goaf is high, the controller As the top beam rises to a hig...
