Embodiment Construction

[0026] As shown in the figure: the circulating self-moving support support assembly for gob-side entry retaining in this embodiment includes a left support group, a right support group and a flexible track arranged between the left and right support groups for supporting the roof of the roadway 6. The flexible track can use chains, lock chains, triangle belts, steel wire ropes, etc.; the left bracket group and the right bracket group are composed of unit brackets 1. The telescopic column 10, the vertical direction refers to the direction extending forward and backward along the roadway, the telescopic column can adopt structures such as hydraulic jacks and hydraulic cylinders, and the specific structure is the prior art, so it will not be repeated here; Transport mechanism for the unit stand 3 . Of course, there is also a driving device for driving the rotation of the flexible track, and its specific structure is the prior art, so it will not be repeated here.

Abstract

The invention discloses a gob-side entry retaining circulating self-moving type support bracket assembly. The gob-side entry retaining circulating self-moving type support bracket assembly comprises aleft bracket group, a right bracket group and a flexible rail disposed between the left bracket group and the right bracket group, and the left bracket group, the right bracket group and the flexiblerail are used for supporting a back; the left bracket group and the right bracket group are formed by combining unit brackets, and the unit brackets comprise longitudinally extending top beams and retractable stand columns for supporting the top beams. The flexible rail is provided with a transporting mechanism for the transporting the unit brackets. The gob-side entry retaining circulating self-moving type support bracket assembly adopts the longitudinally extending top beams, during long-distance transportation of the unit brackets, only the retractable stand columns are required, the top beams do not need to be set as telescopic structures, the structure is simple, the manufacturing cost is reduced, retraction time of the unit brackets is reduced, and the work efficiency is improved; and the longitudinally extending top beams are adopted to prevent interference between the top beams and the flexible rail, and transportation of the unit brackets along the flexible rail is smoother.

Description

technical field [0001] The invention relates to the technical field of mine support, in particular to comprehensive mechanized coal mining roadway support equipment in coal mines, and in particular to a circulating self-moving support bracket assembly along gob-side roadway retention. Background technique [0002] The essence of roadway retention along the gob is to maintain the original mining roadway along the edge of the goaf after coal mining in the working face. In order to recover the protective coal pillars left in the traditional mining method. Use certain technical means to reserve the re-support along the channel of the previous section for the use of the next section. This method of retaining entry is to keep the original slot along the edge of the goaf, which is called retaining entry along the goaf. Gobside alley retention can maximize the recovery of resources. Avoid coal loss. It is a relatively advanced coal mining roadway layout method, which can reduce ...
