Description

A kind of alley hydraulic support
Technical field
The present invention relates to a kind of hydraulic support, particularly a kind of alley hydraulic support.
Background technology
Impulsion pressure is a kind of typical mine power phenomenon, with great harmfulness.This dynamic phenomenon moment will The great number of elastic deformation energy accumulated in coal and rock discharges in form drastically, fierce, causes coal and rock to destroy and produce strong Broken coal petrography is thrown to roadway digging space, sends the strong sound by vibrations, power, causes device damage, roadway destruction and people Member's injures and deaths etc..
As pit mining depth down, mining rate are increased, mining distribution becomes complicated, stress bar residing for digging country rock Part runs down, and resulting impulsion pressure disaster drastically increases, strengthened.The mine of overbump ore deposit pressure, impact occurred in the past Ore deposit pressure disaster is more serious, the mine not occurred in the past, gradually starts generation impulsion pressure and shows.
It is a kind of measure of effective prevention impulsion pressure that supporting is carried out to coal-face and tunnel.By being pushed up to tunnel Base plate and two help to apply setting load, roadway deformation can be prevented, prevention roadway bump destruction.Therefore, safe, practical supporting is researched and developed Equipment is significant for the safety and high efficiency of impulsion pressure mine.
Hydraulic support is the support apparatus of comprehensive mechanical coal mining, and coal-face is applied to existing hydraulic support more, its Major function is supporting Stope roof, safeguards the working space of the equipment such as coal-winning machine and drag conveyor, and in company with working face Harvesting equipment is moved forward.Such hydraulic support can be very good support works face top board, and prevention ore deposit pressure shows, and has ensured work The safe working in face.But the tunnel for equally existing danger of burst, but can be very good supporting without a kind of hydraulic support, because This, it is necessary to develop a kind of hydraulic support for being specifically applied to tunnel.
The content of the invention
The technical problem to be solved in the present invention is to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of tunnel hydraulic pressure branch Frame, the alley hydraulic support is used for the supporting of coal mine roadway, and can roadway's sides and roof and floor be formed with comprehensive supporting, controls lane Road is deformed, prevention roadway bump destruction.
In order to solve the above technical problems, the technical solution adopted by the present invention is:
A kind of alley hydraulic support, including symmetrically arranged two support frames push away beam with flexible.
Each support frame includes base, back timber, front column, rear column, hydraulic jack and flexible back beam.
Between two back timbers of two support frames and beam is pushed away by stretching between two bases to be connected;It is flexible to push away beam Length can adjust.
Front column, rear column and flexible back beam are arranged between back timber and base, wherein, back beam of stretching is by back timber end It is fixedly connected with base end, and flexible back beam height can stretch;The bottom of rear column and front column is fixed with base to be connected Connect, a hydraulic jack is respectively fixedly installed in the top of rear column and front column with back timber, each hydraulic jack Top is hinged with back timber.
Flexible back beam includes the vertical columns and sleeve being mutually slidably matched, and vertical columns bottom is fixed with base end to be connected Connect, sleeve top is fixedly connected with back timber end.
The every flexible beam that pushes away includes the connected mode between two push rods, two push rods using hinge;Two push away The other end of bar is slidably connected with corresponding back timber or base.
Front column, rear column and flexible back beam are vertically set between back timber and base.
Reversal valve is provided with each hydraulic jack.
The present invention has the advantages that using after said structure:
1st, base and vertical columns, back timber and sleeve upper end use overall structure, make hydraulic rack structure more firm, globality It is guaranteed with self stability.
2nd, four hydraulic jacks symmetrically apply support force, and whole support system is more balanced, and the support force applied is more Greatly, make that the security of hydraulic support is higher, supporting effect is more preferable.
3rd, by hydraulic jack and it is flexible push away beam action, the horizontal and vertical bidirectional modulation of hydraulic support can be realized. All there is stronger applicability for the tunnel of different in width and height.
4th, the lift in height of hydraulic support is by reversal valve control, and control system is succinct.
5th, simple in construction, easy to operate, lightweight, intensity is high, stability is strong, is easy to fill, tears open, operates industry, with fine Promotion prospect and application value.

Fig. 1 shows a kind of structural representation of alley hydraulic support of the invention.
Fig. 2 shows the structural representation under a kind of alley hydraulic support contraction state of the invention.
Fig. 3 shows Fig. 1 Section A-A view.
Wherein have:1- bases, 2- rear columns, 3- front columns, 4- hydraulic jacks, 5- is flexible to push away beam, 51- push rods, 52- pins Axle, 6- back timbers, 7- stretches back beam, 71- vertical columns, 72- sleeves.
Embodiment
Supporting embodiment below in conjunction with the accompanying drawings and specifically, the present invention is further detailed explanation.
As shown in Figure 1 to Figure 3, a kind of alley hydraulic support, including symmetrically arranged two support frames push away beam 5 with flexible.
Each support frame includes base 1, back timber 6, front column 3, rear column 2, hydraulic jack 4 and flexible back beam 7.
Between two back timbers of two support frames and beam is pushed away by stretching between two bases to be connected;It is flexible to push away beam Length can adjust.
It is flexible push away beam telescopic be every in prior art, the present invention it is flexible push away beam and preferably include two push away Bar, as shown in figure 1, the connected mode being hinged between two push rods using bearing pin 52;The other end of two push rods with it is corresponding Back timber or base be slidably connected.One end as back timber or base are connected with push rod is set to be hollow, and push rod can be along middle cavity Slide.
Front column, rear column and flexible back beam are vertically set between back timber and base, wherein, back beam of stretching is by back timber End is fixedly connected with base end, and flexible back beam height can stretch.Flexible back of the body depth of beam is stretched for prior art, sheet Vertical columns and sleeve that back beam of being stretched in invention preferably includes mutually to be slidably matched, vertical columns bottom is fixed with base end Connection, sleeve top is fixedly connected with back timber end.
