Abstract

The invention relates to an advanced support device of a coal mine fully mechanized mining working surface lane, in particular to a self-circulation type advanced hydraulic support. The self-circulation type advanced hydraulic support consists of a walking part, a frame part and a plurality of support parts, wherein, the frame part is arranged on the walking part and can be telescopic and supportthe support parts for walking, and a plurality of support parts are supported in the lane; when the self-circulation type advanced hydraulic support needs to be moved forward, the manual handling is unnecessary, only the support parts need to be contracted for being supported on the frame part, the walking part advances and then the support parts are well supported. The self-circulation type advanced hydraulic support can improve the safety of a support environment of the fully mechanized mining working surface ventilation lane, reduce the labor intensity of miners, improve the support speed of a fully mechanized mining working surface and accelerate coal production.

Description

Technical field

[0001] The invention relates to a kind of advanced support equipment for a fully mechanized coal mining face roadway, in particular to a self-circulating advanced hydraulic support. Background technique

[0002] At present, single hydraulic props and metal roof beams or large slabs are generally used in the advance support of fully mechanized mining face roadways. The disassembly, movement and support of single hydraulic props are completely carried by human hands and shoulders. Workers are labor intensive, require a lot of manpower, laborious and unsafe, which is extremely inconsistent with automated fully mechanized mining face. Summary of the invention

[0003] The purpose of the present invention is to provide a self-circulating advanced hydraulic support that can reduce the labor intensity of miners and has high safety.

[0004] The invention is composed of a walking part, a frame part, and a plurality of bracket parts. The frame part is composed of a lifting m...
