Background technology
In exploitation during colliery, advance support be guarantee that excavation coal mine work area is stable and take be ahead of driving face at a kind of ancillary method of roadway support top board.What current forepoling hydraulic support was generally taked is step-by-step movement bar timbering top board, although this method for supporting is simple and convenient easy to operate, to the large effectively roof supporting of top plate supporting power, but this support pattern is roof supporting repeatedly, be unfavorable for the safety management of top board and maintenance, easily cause the fragmentation of top board, underworkings staff life and equipment are threatened, simultaneously, install, safeguard, intensity of workers is very large while dismantling this support, for this reason, we propose a kind of crawler type lame advanced supporting hydraulic support.
Utility model content
The purpose of this utility model is to provide a kind of crawler type lame advanced supporting hydraulic support, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of crawler type lame advanced supporting hydraulic support, comprise back timber crawler belt, upper driving wheel, hydraulic vertical prop, lower driving wheel, base crawler belt, undersetting wheel, base skeleton, lower directive wheel, upper directive wheel, upper thrust wheel, back timber skeleton and quadric chain, described back timber crawler belt is arranged on driving wheel and upper directive wheel, and described upper thrust wheel is arranged on back timber skeleton; The same driving wheel of described back timber skeleton is connected with upper directive wheel; Described quadric chain connects the middle part of back timber skeleton and base skeleton, described hydraulic vertical prop has two, tie-beam skeleton and base skeleton, described base crawler belt is arranged on lower driving wheel and lower directive wheel, described base skeleton connects lower driving wheel and lower directive wheel, and described undersetting wheel is arranged on base skeleton top.
Preferably, on described back timber skeleton and undersetting wheel, be respectively equipped with the motion guide groove of thrust wheel and undersetting wheel.
Preferably, the same driving wheel of described back timber skeleton and upper directive wheel junction are equipped with bogie structure.
Preferably, described upper driving wheel and lower driving wheel place are equipped with gasoline engine structure.
Operating principle: the leading hydraulic prop support of crawler type, what take is upper and lower crawler belt (back timber crawler belt and base crawler belt) formula structure, back timber is equipped with back timber crawler belt, back timber crawler belt directly contacts support to top board, take tumbling-type to move ahead, back timber crawler belt move ahead resistance be and top board between force of rolling friction, the resistance that moves ahead is less, and advance in process, top braces crawler belt is fitted with top board always, there is not the problem repeatedly supporting to top board, improved the protective capability to top board, be conducive to the safety management to top board, and crawler type forepoling hydraulic support is advanced into tunnel work before can be motor-driven, reduced staff's labour intensity, secure to underworkings staff's life security and equipment, base crawler belt can be used as the power source advancing.
Compared with prior art, the beneficial effects of the utility model are: this crawler type lame advanced supporting hydraulic support, the mode that adopts the rolling of back timber crawler type to move frame can realize band year and move ahead, reduced to greatest extent the number of times of support repeatedly to top board, use the flexible support of crawler belt can reduce the destruction to top board simultaneously, can overcome well above-mentioned deficiency, be conducive to the safety management of top board and maintenance, for constructor, unit in charge of construction provide better construction environment, there is good economic benefit.
