Abstract

Movable equipment used for a down hole heavy support comprises a conveying track mounted in the supporting range of the heavy support, and the conveying track is formed by segmented tracks through connecting cards in a lapped and joint mode; on the side, where the heavy support is located, of the conveying track and in the position where the connecting cards are located; the conveying track is further fixed to a top beam of the roadway through a plurality of connecting chains located above, and the horizontal of the track surface is maintained; the two ends of the conveying track are provided with two curved track segments with opposite turning directions, and the track surfaces of the two curved track segments are maintained horizontal, and connected back to the track surface of the conveying track in return after being bent toward one side of the conveying track; and the conveying track is provided with a draft device, the draft device is provided with a connecting piece for installing the heavy support. According to the movable equipment used for the down hole heavy support, the need of the fast moving of the mine hole hydraulic pillar can be met, the labor intensity of the workers can be relieved, the security is improved, the production efficiency of the fully mechanized coal mining face is improved, and the drawback that a top plate is repeatedly supported by a traditional moving support can be avoided.

Description

technical field [0001] The invention relates to an underground supporting equipment, in particular to a mobile equipment for an underground heavy support, which is suitable for the supporting place of the recovery roadway of the fully mechanized mining working face in the underground. Background technique [0002] The mining roadway support of the underground comprehensive mechanized coal mining face is extremely important, and it is a necessary condition to ensure the normal operation and ventilation of the coal mining face. Due to the complex underground conditions, the mining of the working face will cause the roof of the mining roadway to fall, and there will be slabs. This phenomenon seriously affects the coal mining operation and personnel safety, so the backing of the mining roadway has become a very important subject, especially the deformation of the roadway in the advance support section is serious, the advance pressure is large, and the quality of the support will ...
