The suspension hydraulic support is mainly used in blasting mining working face, as well as fully mechanized mining working face.
Description
Technical field
The utility model relates to the support apparatus that mine underground mining work plane uses, and is specially adapted to the suspension moving hydraulic support of the band flip beam of colliery underground mining work plane use.
Background technology
At present, the domestic colliery existing support apparatus kind of underground mining work plane is more, some equipment can not solve by coal group and blow out back temporary lining problem and the safety problem during mobile back timber repeatedly, destroy original stability of stope top board and integrality, the pillar pitch smaller influences the pedestrian space before and after making simultaneously, and work is inconvenient, shortcomings such as maximum defective is to have potential safety hazard, and operating efficiency is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, processing, easy to maintenance, the suspension moving hydraulic support of safe and reliable band flip beam for the cantilever support that uses the mine down-hole.
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, front standing pillar, back prop, hydraulic jack, waste rock board, post boots to form.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.Two hydraulic props in front lower place and trave lling girder are articulated and connected on supporting seat, can move forward and backward.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 turnover flip beam that is articulated and connected, and flip beam adopts dull and stereotyped reinforcement one structure, flip beam hydraulic jack one end and turnover flip beam are articulated and connected, and the other end and back timber are articulated and connected.
The utility model compared with prior art, and is rational in infrastructure, processing, easy to maintenance, safe and reliable, solve stope effectively and be sidelong the empty top situation that occurs behind the big gun by coal group, eliminate safe hidden trouble, raise labour productivity, be mainly used in blast mining face, also be suitable for fully-mechanized mining working and use.

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:
Shown in accompanying drawing, Fig. 1 is a front view, by preceding dragging beam, after drag beam, back timber, trave lling girder, supporting seat, two flexible hydraulic props, hydraulic jack, waste rock board, the post boots are formed, beam 7 is dragged in its two front and back that are arranged in parallel, 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 back timber 4 belows, 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 3,8 bottoms are inserted in the post boots 14, the back timber 4 front ends turnover flip beam 12 that is articulated and connected.Flip beam hydraulic jack 13 1 ends and turnover flip beam 11 are articulated and connected, and the other end and back timber are articulated and connected, and described compression spring device 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.
With flip beam hydraulic jack 11 with its flip beam 10 releases, upset, in running order.When not working, it is retracted, be in off working state by its hydraulic jack 11.
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 and flip beam hydraulic jack all are in retracted mode, and forward and backward pillar carrying is supported on whole frame body on the base plate.The flip beam hydraulic jack stretched out after machine was adopted operation, will make the flip beam upset, formed temporary lining.
Fig. 2 is a state behind the explosion coal-falling, and the staff is produced coal under the flip beam supporting.After the operation of producing coal is finished, regain the flip beam hydraulic jack, flip beam will be regained.After regaining, flip beam with the forward and backward pillar post unloading of support and mention, can carry out the following frame operation that moves.
Figure 3 shows that the frame state that moves, after forward and backward pillar is mentioned, hydraulic jack 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, owing to drag beam to fix, promptly hydraulic jack is dragging Liang Yiduan to fix, and the thrust of Xing Chenging will make reaches such as back timber and front and back pillar thus.
Figure 4 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.
So finish the circulation of a duty, get back to state shown in Figure 1.
