Along with the continuous increase of coal mine machinery and coal-face quantity, the supporting of fully-mechanized mining working two crossheading top boards management is quite important, has become one of key factor that affects working surface production efficient.At present, fully-mechanized mining working two crossheading advance supports generally adopt cross metal hinged girder (or a word beam) to cooperate the individual prop support pattern, adopt manpower to install, withdraw hydraulic prop, cause labor strength large, cost is high, and prop drawing is dangerous large, exist potential safety hazard, and it is current to affect personnel and equipment, and roadway's sides can't carry out supporting, and supporting effect and safety guarantee are undesirable.And individual prop all can not adapt to this high-yield and high-efficiency fully mechanized coal face to the requirement of advance support from aspects such as support capacity, supporting height, support speed, automaticity, operability, safeties, the crossheading advance support has become the bottleneck of restriction large-mining-height working surface high-yield and high-efficiency, has restricted to a great extent the performance of high-performance fully-mechanized mining equipment high-yield and high-efficiency ability.
Summary of the invention
The utility model adopts hydraulic prop in order to solve existing crossheading advance support, and the problem such as have that labor strength is large, support cost is high, supporting effect and safety guarantee are undesirable provides a kind of crossheading split type advanced hydraulic support group of taking a step.
The utility model is to adopt following technical scheme to realize: the crossheading split type advanced hydraulic support group of taking a step, be set up in parallel about comprising, and the two cover support bodys that structure is identical, every cover support body comprises the preposition support that at least three front and back are arranged in order, middle stand and rearmounted support, preposition support, the structure of middle stand and rearmounted support includes base, back timber, be connected with column between base and the back timber, also arrange by front rod between base and the back timber, the quadric chain that back link and caving shield consist of, preposition support wherein, be supported with two root posts between the back timber of rearmounted support and the base, innovative point of the present utility model is that the back timber two ends of middle stand are provided with articulated roof beam, the base two ends are provided with articulated base, the articulated roof beam front portion is provided with front-axle beam, and four root posts are supported on respectively back timber and base, between articulated roof beam and the articulated base; Move oil cylinder and is connected by drawing between the frame by two cover hydraulic pressure automatic controlling system between the preposition support of same set of support body and the base of middle stand, move oil cylinder and be connected by overlapping to draw between the frame of hydraulic pressure automatic controlling system by one between the base of middle stand and rearmounted support; Between the back timber and back timber of adjacent two cover support bodys, be connected by anti-down adjusting oil cylinder between the frame by the hydraulic pressure automatic controlling system between base and base.
In the practical operation, two cover support bodys arranged side by side are arranged in the both sides, tunnel, adjust each hydraulic support by the hydraulic pressure automatic control system, along with work plane is pushed ahead, when moving frame, first one of mobile tunnel one side cover support body specifically from moving past journey is, frame is fallen in preposition support, make itself and back timber break away from top board, then draw between adjusting bracket and move oil cylinder its piston rod is stretched out, with middle stand as fulcrum, with preposition support reach, and then rise preposition support and make its back timber support top board, again frame is fallen in middle stand, then draw between adjusting bracket and move oil cylinder and make its piston rod retraction, the reach of pulling middle stand, the reach of rearmounted support can repeat above-mentioned steps, pushes away one through one and draws, and a whole set of support body can move forward a segment distance, then adopt identical method to move another set of support body, the realization support alternately takes a step to move forward.
The back timber outside of described preposition support, middle stand and rearmounted support and the articulated roof beam outside of middle stand all are hinged with the rollover beam, can strengthen the supporting scope, guarantee supporting effect.
Compared with prior art, the professional support apparatus that the utility model designs for working face crossheading advance support, each cylinder action take hydraulic pressure as dynamic Control, outrigger before and after back timber adds, the left-right rollover beam, can carry out effective support to the crossheading top board, split-type structural takes a step to advance, substitute traditional hydraulic prop as the operating type of advance support, realize certainly moving of advance support rack, improve advancing velocity, simplify the supporting program, alleviate labor strength, improve coal production efficient, strengthen coal mine production safety, improve the high-yield and high-efficiency of fully-mechanized mining working, and can effectively avoid support repeatedly to support destruction to top board.
