Description
Technical field
The utility model relates to the support apparatus that mine underground mining work plane uses, particularly a kind of a kind of suspension moving hydraulic support with forestope that is used for colliery underground mining work plane.
Background technology
At present, the existing support apparatus of domestic colliery underground mining work plane, normal its shortcoming that exists, do not have forestope form of structure to use, can not solve by coal and help to blow out back temporary lining problem, mobile repeatedly back timber, destroy original stability of stope top board and integrality, the pillar pitch smaller influences the pedestrian space before and after making simultaneously, has potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure for the cantilever support that uses the mine down-hole, processing, a kind of suspension moving hydraulic support with forestope easy to maintenance, safe and reliable.
In order to overcome the defective that prior art exists, the technical solution of the utility model is to solve like this: by preceding Tuo Liang, after drag beam, back timber, trave lling girder, two flexible hydraulic prop, hydraulic jack, waste rock board, post boots to form.Its improvements of the present utility model are that two front and back that are arranged in parallel drag beam to be articulated and connected with boxboard, one end and the back timber of a hydraulic jack are articulated and connected, the other end with after drag beam to be articulated and connected, two of front and back drag beam to adopt compression spring device to be suspended on the back timber below.Two hydraulic props in the back timber back lower place are articulated and connected on supporting seat, do not relatively move with back timber, and two hydraulic props in front lower place are articulated and connected on the supporting seat of trave lling girder.Waste rock board is equipped with in the back timber back lower place, the hydraulic prop bottom is inserted in the post boots, the back timber front end has scalable preceding spy beam, scalable forestope adopts box structure, its front end is welded on the end plate, the back timber front end is inserted in the rear end, below left and right sides symmetric arrangement at least one forestope hydraulic jack.Said forestope also can be formed steel construction or round steel pipe structure.
The utility model compared with prior art, and is rational in infrastructure, and processing, easy to maintenance, safe and reliable solves stope effectively and has been sidelong the empty top situation that occurs behind the big gun by coal group, eliminates safe hidden trouble, and raises labour productivity.

The specific embodiment
Accompanying drawing is a concrete embodiment of the present utility model.
Below in conjunction with accompanying drawing the present utility model content is described further:
With reference to Fig. 1, shown in Figure 2, a kind of suspension moving hydraulic support with forestope, by preceding dragging beam, after drag beam, back timber, trave lling girder, two flexible hydraulic props, hydraulic jack, waste rock board, the post boots are formed, its improvements of the present utility model are that two front and back that are arranged in parallel drag beam 7,5 usefulness boxboards 9 are articulated and connected, one end and the back timber 4 of a hydraulic jack 6 are articulated and connected, the other end with after drag beam 5 to be articulated and connected, beam 7 is dragged in two of front and back, 5 adopt compression spring device to be suspended on 4 belows, top, two hydraulic props 3 in back timber 4 back lower places are articulated and connected on supporting seat 2, do not relatively move with back timber, two hydraulic props in front lower place 8 are articulated and connected on supporting seat 11 with trave lling girder 10, trave lling girder 10 moves forward and backward with hydraulic jack 6, waste rock board 1 is equipped with in back timber 4 back lower places, hydraulic prop 3 bottoms are inserted in the post boots 14, back timber 4 front ends have scalable forestope 12, scalable forestope 12 adopts box structure, its front end is welded on the end plate, back timber 4 front ends are inserted in the rear end, below the left and right sides arrange at least one forestope hydraulic jack 13, said compression spring device is to be built-in with cylindrical compression spring by spring spool, and cylindrical compression spring is built-in with connecting link pin and forms.When back timber 4 is subjected to front standing pillar 8, back prop 3 to upper support, drag the connecting link pin compression spring of beam in spring spool, to slide.Described front and back drag beam to adopt two groups of compression spring devices at least, hang under the back timber.
The forestope hydraulic jack 13 that whole forestope is arranged by bilateral symmetry is with its release, and is in running order.By its hydraulic jack it is retracted when not working, be in off working state.
Accompanying drawing is depicted as the dynamic duty process of support that this example is realized:
Figure 1 shows that this support initialization state, hydraulic jack 6 and forestope hydraulic jack 13 all are in retracted mode, and forward and backward pillar carrying is supported on whole frame body on the base plate.Forestope hydraulic jack 13 stretches out after carrying out perforating, shot firing operation, and forestope 12 will be stretched out, and forms temporary lining.
Fig. 2 is the vertical view that removes the back timber top board of state shown in Figure 1.
Fig. 3 is a state behind the explosion coal-falling, and the staff is produced coal under forestope 12 supportings.After the operation of producing coal is finished, regain forestope hydraulic jack 13, forestope 12 will be regained.After regaining, forestope 12 with the forward and backward pillar post unloading of support and mention, can carry out the following frame operation that moves.
Fig. 4 removes the vertical view of back timber top board for state shown in Figure 3.
Figure 5 shows that the frame state that moves, after forward and backward pillar is mentioned, hydraulic jack 6 is stretched out, can promote this support (dragging except the beam) reach.
Promptly drag beam and ground relative fixed, therefore by drag beam with whole support because beam and two adjacent supports connections are dragged in front and back this moment.When stretching out hydraulic jack 6, owing to drag beam to fix, promptly hydraulic jack 6 is dragging Liang Yiduan to fix, and the thrust of Xing Chenging will make reaches such as back timber 4 and front and back pillar 8,3 thus.
Fig. 6 removes the vertical view of back timber top board for state shown in Figure 5.
Figure 7 shows that support reach back state, after the support reach front and back column is stretched out carrying and form support, after treating the unified reach of entire working surface support, again the hydraulic jack of entire working surface support is withdrawn, this moment is by forward and backward shore supports, be that pillar and back timber etc. are fixing, the pulling force that hydraulic jack forms will make the beam integral body of dragging of entire working surface support move forward.
Fig. 8 removes the vertical view of back timber top board for state shown in Figure 7.
So finish the circulation of a duty, get back to state shown in Figure 1.
