Description
Technical field
The present invention relates to a kind of light-duty back timber formula hydraulic support that is used for coal-face supporting roof under the coal mine.
Background technology
Hydraulic support divides fully mechanized mining supporter and hydraulic prop for sliding mine caps two big classes, and the present invention is marginal a kind of back timber formula hydraulic support.Its background technology is the technology described in the Chinese coal industry " hydraulic prop for sliding mine caps general technical specifications ".Prior art in this field has hydraulic prop for moving suspended top beam (Chinese patent application number 88104291.9); Triadius type hydraulic support (Chinese patent application number 96209441.2); Block form hydraulic prop for sliding mine caps (Chinese patent application number 91200747.8) etc.Above-mentioned these supports, all by hydraulic prop, preceding beam moves the frame cylinder, and two back timbers and two groups of linkages etc. are partly formed.Because back timber all is narrow split type back timber, do not keep off the cash device again, thus all must tie up the top net during caving coal, so increased cost of ton coal.A kind of retaining cash formula hydraulic support is arranged, though can the caving coal, also because every is made up of two narrower back timbers,, still need to tie up the top net so the solution of still failing of the problem of cash is leaked at the top.Linkage between two back timbers in every support of above-mentioned in addition support all is made up of connecting rod slider mechanism or connecting rod guide-bar mechanism, distance between their two back timbers is all fixed, so uncontrollable direction in the process of pushing ahead, deflection all can take place in the direction of every propelling one segment distance support, therefore need regularly to stop production and transfer frame, influence output, and also dangerous when transferring frame.A kind of steering hydraulic support (Chinese patent application number 98101279.5) is arranged in addition.Its form of structure is that every pack support is made up of two narrower back timbers arranged side by side.This support can be adjusted the direction that back timber is pushed ahead with manpower by lever, safety also takes a turn for the better to some extent when transferring frame, but transfer direction by manpower because be, labour intensity is big, sometimes also transfer motionlessly, have to spur back timber, can take the production time so again with lifting gears such as chain slings, influence output, this support caving of this external application coal also must be tied up the top net.Also has a kind of hydraulic support that adopts integral top beam, lift-moving type hydraulic support (Chinese patent application number 97100626.1) etc. for example, the back timber broad of this class hydraulic support, empty top area is little, can as fully mechanized mining supporter, not tie up top net caving coal, but since the back timber of this class support and its below run through lifting of entire working surface certain annexation of setting a roof beam in place, limited certain back timber amplitude of rising separately, so relatively poor to the adaptive capacity of ceiling not.In addition and since lift this support of the restriction of setting a roof beam in place can not lean on the fluid power controlling party to, so every propelling one segment distance needs special holder orientation and the adjustment rack spacing adjusted, influence output.
Certainly fully mechanized mining supporter can not tied up top net caving coal, but fully mechanized mining supporter weighs tens tons, costs an arm and a leg, tight to the geology conditional request, the down-hole carrying is inconvenient, and general colliery is with not rising, especially fully mechanized mining supporter can only be used for machine and adopts, and can not be used for big gun and adopt, and institute so that apply is restricted.
Summary of the invention
The technical problem to be solved in the present invention provides the part that a kind of weight has only fully mechanized mining supporter, convenient in carrying can be regulated direction, laborsaving, quickly to the ceiling adaptive capacity is not strong in progradation, can not tie up caving coal under the net situation of top, can be used for the hydraulic support of blast mining face.For addressing the above problem, chain suspension type hydraulic support of the present invention comprises integral top beam, hydraulic prop from the vertical below of back timber, preceding beam and preceding beam oil cylinder, be hinged on going up of top beam rear end and keep off the cash device, the lower waster rock blocking device of pressing pillar to connect together with the back discharge opeing, the sliding part that on the back timber guide rail, slides, it is characterized in that and to slide along the side of integral top beam, and by connector with move have at least on the joining sliding part of frame cylinder a chain and or wire rope be attached thereto, chain with or the other end of wire rope be connected with adjacent hydraulic support.
Described chain can be the thin and long units made from several end to end connecting rods.
Described move frame cylinder one end and back timber hinged, the other end is connected with sliding part, sliding part is connected with force transmission element on being connected adjacent frame back timber.The end and the back timber that move the frame cylinder in another embodiment are hinged, the other end directly be connected adjacent frame back timber on force transmission element be connected.Can also be that to move an end and the back timber of frame cylinder hinged, the other end directly be hinged on the back timber of adjacent frame.
On back timber, or on sliding part, be provided with several adjustment holes of adjustable pitch chain or rope capacity.
Described force transmission element is elongated connecting rod, also can be to be hinged on fork that can swing up and down on the adjacent frame back timber or the slide block that can slide up and down along the perpendicular guide rail of adjacent frame back timber side.
After adopting such structure, just can be by controlling the flexible of every back timber two sidesway frame cylinders, laborsaving, move frame quickly, but and the control bracket direction of pushing ahead, the big problem of labour intensity when having solved steering hydraulic support and stirring the vertical pendulum bar and carry out tuning with lever by manpower.When being pushed down by the spoil of inbreak above the back timber, by move the huge strength of frame cylinder can push away moving back timber, thereby cantilever support, block form support, steering-type support, lift-moving type hydraulic support etc. have been solved, holding time was long when the method that needs to hang with other lifting gear pulling back timbers such as chain sling was sometimes transferred frame, influenced the problem of output.Owing to move among the crack that the frame cylinder places adjacent two set caps,, adopt so can be used for big gun so be difficult for crumbling when blowing out.All adopted between each back timber of chain suspension type hydraulic support of the present invention on all directions all movable freely chain and or the wire rope ways of connecting, so not only transfer frame laborsaving, and the up and down scope of each back timber is bigger, therefore is best suited for the not supporting of ceiling.
Because chain suspension type hydraulic support has adopted the monolithic back timber, back timber is wide, the frame spacing is little, band retaining cash device again, so the caving coal can not tied up the top net, when having solved frame type caving coals such as cantilever support, block form support because of tiing up the problem that the top net causes the cost of ton coal raising.
