Description

The airborne temporary lining of development machine
Technical field
The utility model belongs to the airborne temporary lining of development machine of boring head temporary lining safety under the improvement of temporary lining under the coal mine, particularly coal mine.
Background technology
The temporary lining form that generally use in present domestic colliery is artificial supporting operation, there are string pipe forestope and pillar to add the crossbeam dual mode, this dual mode all is to go here and there to manage forestope and manually build pillar with the artificial unloading to add crossbeam, and maximum problem is to still have safe weak link.The airborne temporary support device of existing a kind of development machine because of being subjected to the restriction of its structure design, makes temporary lining not in place in advance, can not protect Anchor Care workman's safety effectively, and the versatility of this temporary lining is poor in addition, is subjected to the restriction of tunnel size.
Summary of the invention
The purpose of this utility model is to provide a kind of development machine airborne temporary lining, in the down-hole mining process, not only can realize mechanization supporting operation, reduce workman's construction intensity, improve drivage efficiency, and supporting can put in place in advance, is not subjected to the restriction of tunnel size, and workman's safety is protected.
The utility model is achieved in that the airborne temporary lining of a kind of development machine, comprise development machine, the afterbody of upset support arm is hinged on the anterior affixed preceding bearing of tunneling machine cutting portion housing, be positioned at the monosymmetric overturning oil cylinder of upset support arm, its afterbody is hinged on respectively on the affixed tail-holder rack of tunneling machine cutting portion housing, its piston rod end of overturning oil cylinder of symmetry is hinged on respectively on the outer wall of upset support arm, the frame that stretches out by the telescopic oil cylinder control in the upset support arm is installed in the pipe column type upset support arm movingly, stretch out the articulated top board steelframe in end of frame with steel pipe drawing and pulling type fence structure, the piston rod end of supporting oil cylinder is hinged on the back side of the top board steelframe with steel pipe drawing and pulling type fence structure, and its afterbody is hinged on the outer wall of upset support arm.
During work, hydraulic oil from the development machine pumping plant is controlled the overturning oil cylinder that enters symmetry through hydraulic control system, utilize the overturning oil cylinder of the symmetry support arm that will overturn to overturn, reach the operating angle that needs, extract the steel pipe drawing and pulling type fence on the top board steelframe out the expansion location with manual type, place protecting wire net thereon, the supporting oil cylinder will have the top board steelframe upset that launches steel pipe fence and put in place, at this moment handle the height of telescopic oil cylinder control top board steelframe, make it reach top, cut district, the staff just can play the anchor pole operation in the bottom of top board steelframe safely by the neutral gear of steel pipe fence.Because hydraulic operated temporary lining is installed on the development machine, moves with big gun head and cutting units.Airborne temporary lining of the present utility model system has substituted original temporary lining mode, and the adverse circumstances that adapt to the scene, down-hole have guaranteed construction safety.The utility model is very little to the transformation amount of development machine, do not disturb the motion of development machine and cut, loading operation function, realized mechanization supporting operation, reduced workman's construction intensity, improved drivage efficiency, and realize that supporting puts in place in advance, and be not subjected to the restriction of tunnel size, make Anchor Care workman's safety obtain ensureing effectively.After having worked, the steel pipe fence of top board steelframe is drawn in, and temporary lining is backed by hydraulic cylinder.
