The utility model discloses a fully hydraulic walking type temporary support frame used in mines or for the driving process in the tunnel engineering, which has a hydraulic metal structure and mainly comprises a front and a rear top beams, an upright post, a front and a rear supporting beams, a frame beam, a shifting beam, a telescopic beam, a cantilever beam, a hydraulic pump, a jack, etc. The operation of the support frame is realized by the jack through a combined operating valve, the travel type of the support frame is a leg lifting walking type, and the hydraulic jack can ensure that the telescopic beam and the cantilever beam can support a suspended green roof in time. The utility model can avoid fatal accidents caused by the roof fall of surrounding rocks, all driving procedures are completed under the protection of the temporary support frame, and the parallel operation of boring, muck loading and supporting procedures can be realized. The utility model capable of reducing workers' physical labor belongs to an indispensable safety device in mines or the driving engineering.
Description
The utility model belongs to the mining technique field, the falsework during especially for tunnelling.
Prior art in this area has the supporting of simple and easy forestope formula, roadway support manipulator, its support body suspension arrangement is hung on permanent shed, the empty top top board that is exposed is supported in temporary lining by the joist cover frame, be exactly to utilize the robot support top board in addition, it is that the sky top area is big that there is not enough place jointly in the supporting of these forms, the labor strength height does not fundamentally solve the driving workman and be engaged in headwork in the environment of a safety.
The purpose of this utility model is to solve the falsework that a kind of hydraulic walking type moves frame automatically, and its falsework makes every effort to simple in structure, is easy to realize mechanized, makes support the place ahead not have the sky top area to expose, to guarantee workman's safety work.
The technical solution of the utility model is achieved like this: a pumping plant is arranged in the back of falsework, pumping plant is connected by high-pressure hose, one way valve, reversible lock, safety valve, elbow etc. with jack in the falsework, form the after-frame back timber at the afterframe and the mobile brace summer of symmetry, at least 4 unloading beams are installed in the middle of afterframe, its both sides are respectively equipped with 2 passing jack, front baffle and symmetrical fixed support beam are formed the side arm back timber, guide peg is installed in the ears or side handles of a utensil of fixing support rack, is provided with the thruster jack of symmetry below the fixed support beam.Former and later two back timbers are fixedlyed connected with crossbeam by trave lling girder, safety net is established in the centre, extensible canopy jack one end is fixed on the brace summer, the other end is installed on the carrier bar, carrier bar is connected with guide peg again, establish flexible expansion bend in the middle of carrier bar and side arm back timber, outrigger and carrier bar are articulated and connected, and the outrigger jack also are installed below it.8 root post oil cylinders are installed below mobile brace summer and fixed support beam, and the protection tube is arranged at column oil cylinder top, and the bottom is established and added long leg and post boots, on the protection tube pull bar and eyelid retractor is arranged, and the box that resets is connected with the column oil cylinder with pin.The flexible of jack in the support controlled by control valve.
The utility model compared with prior art, it is flexible that it has easy to operate, an automatic walking, alleviate the manual labor that the workman moves frame, omnibearing supporting driving face, promptly do not have the characteristics of empty top board exposed area, thereby solved the safety problem of driving face workman operation, simultaneously rational in infrastructure, easy to maintenance, be the indispensable support apparatus of mine and tunnel work.
Fig. 1 is the utility model structure elevation;
Fig. 2 is the utility model structure vertical view.
Accompanying drawing is a specific embodiment of the present utility model, and the utility model is described in further detail below in conjunction with accompanying drawing:
With reference to Fig. 1; Fig. 2 after-frame beam 1 is formed the after-frame back timber with the mobile brace summer 2 of symmetry; at least 4 unloading beams 24 are installed in the middle of after-frame beam 1; its both sides are respectively equipped with 2 passing jack 11; preceding frame beam 3 is formed the side arm back timbers with symmetrical fixed support beam 4; in like manner; at least 4 unloading beams 24 also are installed in the middle of the former frame beam 3; guide peg 10 is installed in the ears or side handles of a utensil of fixed support beam 4; be provided with the thruster jack 14 of symmetry below the fixed support beam; promote trave lling girder 5 and crossbeam 6; before inciting somebody to action; the after-frame back timber couples together; safety net 25 is established in the centre; extensible canopy jack 12 1 ends are fixed on the brace summer 4; the other end is installed on the carrier bar 8; carrier bar is connected with guide peg 10 again; in the middle of carrier bar 8 and side arm back timber, establish flexible expansion bend 7; outrigger 9 is articulated and connected with carrier bar 8; outrigger jack 13 also is installed below it; installation at least 8 root post oil cylinders 16 below mobile brace summer 2 and fixed support beam 4; protection tube 15 is arranged at the top of column oil cylinder 16; the bottom is established and is added long leg 20 and post boots 21, has pull bar 22 and eyelid retractor 23 box 17 that resets to be connected with the column oil cylinder with pin 18 on protection tube 15, and stretching of the jack in the support controlled by control valve 19.
When support need move frame automatically, at first start hydraulic power unit and high-pressure emulsion is delivered to control valve 19 by high-pressure hose, be assigned in each jack or column oil cylinder in the support by one way valve, reversible lock, safety valve 3, elbow by control valve 19.Control control valve 19 emulsions are by one way valve, and support side arm four root post oil cylinders shrink, and the side arm back timber leaves top board simultaneously; Control control valve 19 emulsions stretch out side arm by reversible lock, safety valve, jack 11 and are pushed out; Back manipulation valve 19 stretches out side arm column oil cylinder and is the support situation; Control control valve 19 emulsions pass through, and one way valve, safety valve, after-frame four root post oil cylinders shrink, and back timber leaves top board simultaneously; Control control valve 19 emulsions are by reversible lock, safety valve, and jack 11 shrinks after-frame and is pulled; Manipulation valve 19 stretches out after-frame column oil cylinder and is the support situation.
When support needs supporting newly to hang the dew top board, at first start hydraulic power unit, and by high-pressure hose high-pressure emulsion is delivered to control valve 19, manipulation valve 19 process reversible locks, safety valve, elbow are to jack 12,13, reach expansion bend 7 and stretch out, outrigger 9 rises supporting roof.
