Description

A kind of filling hydraulic support with automatic turning bag mechanism
Technical field
The present invention relates to a kind of filling hydraulic support, relate in particular to a kind of hydraulic support with the automatic turning bag mechanism that is applicable to the work plane goaf is carried out filling.
Background technology
Hydraulic support is the key equipment of comprehensive mechanical coal mining, almost in the mine in each colliery, all needs to use.Common hydraulic support designs for common work plane digging at present, its rear portion supporting and space is less, can not carry out large step pitch shielding function with adopting with the breaking roof emitted for some, the more important thing is, when the needs bashing, the pocket that filler is housed must be transported to the place that needs filling from narrow supporting and space, and make it fall into goaf by turning over manually bag, this filling method is not only wasted time and energy, also easily cause danger, affected greatly the safety in production in colliery.
Summary of the invention
The present invention is directed to defect of the prior art, a kind of hydraulic support with large step pitch shielding, automatic turning bag bashing is provided.This hydraulic support has enough supporting intensities in the time of not only can guaranteeing to mine, and can form the supporting and space of super large distance at the afterbody of this support, launch with having of rear portion of shielding the drag conveyor that turns over bag function, carry drag conveyor the fillers such as gangue of the one-tenth bag of coming to be turned in goaf, reach the purpose of bashing.
Technical scheme of the present invention is as follows:
A kind of filling hydraulic support with automatic turning bag mechanism, comprise column, back timber and base, described column is fixedly connected with described back timber and described base, one end of the hinged back screen baffle plate in the rear end of described back timber, the other end of described back screen baffle plate is free end, described back screen baffle plate can be under the driving of rear hydraulic jack rotates around the pin joint of itself and described back timber, be provided with the rear conveyer jack of lateral arrangement on described base, the rear end of described base is connected with the backstop panel seat, be provided with chute between described conveyer jack and described backstop panel seat, be provided with hydraulic jack on the base plate of described chute, be provided with scraper plate in described chute, described scraper plate can move relative to chute.
Be provided with the scraper plate circular hole on described scraper plate.
Described hydraulic jack is arranged in the part of inclined to one side holder orientation of described chute
Described hydraulic jack is connected with the electromagnetic valve on described filling hydraulic support by high-pressure oil pipe.
The invention has the beneficial effects as follows: under the condition that can guarantee hydraulic support stability, meet the needs of goaf filling automatic turning bag.Hydraulic support of the present invention is when mining, and longer back screen baffle plate stretches out with back timber and is positioned on same level under the effect of hydraulic cylinder, and active support filling area breaking roof plays fine protective effect to the drag conveyor at hydraulic support rear simultaneously.
The accompanying drawing explanation
Accompanying drawing 1 is the structural representation with filling hydraulic support of automatic turning bag mechanism of the present invention.
Reference numeral is as follows:
The 1-coal-winning machine; The 2-drag conveyor; The 3-extensible canopy; Hydraulic jack before 4-; The 5-back timber; The 6-column; The 7-high-pressure oil pipe; The 8-base; Hydraulic jack after 9-; 10-back screen baffle plate; The 11-chute; 12-scraper plate circular hole; The 13-scraper plate; Conveyer jack after 14-; The 15-hydraulic jack; The 16-sprocket wheel; 17-backstop panel seat.
The specific embodiment
Referring to accompanying drawing 1, filling hydraulic support with automatic turning bag mechanism, the place ahead of filling hydraulic support is coal-winning machine 1, drag conveyor 2 extractive equipments such as grade, support comprises column 6, back timber 5 and base 8, the front end of back timber 5 is connected with extensible canopy 3, extensible canopy 3 is driven by front hydraulic jack 4, the rear end of back timber 5 is hinged with back screen baffle plate 10, the other end of back screen baffle plate 10 is the free end that with other parts, is not connected contact, also be connected with a rear hydraulic jack 9 between back screen baffle plate 10 and back timber 5, it can rotate around the pin joint with back timber 5 under the driving of rear hydraulic jack 9, thereby regulate the supporting and space of filling hydraulic pressure back-end support, the middle part of base 8 is provided with rear conveyer jack 14, rear conveyer jack 14 lateral arrangement, the direction of jack bar is towards the rear end of filling hydraulic support, the rear portion of base 8 is connected with backstop panel seat 17, the jack bar clamping chute 11 of backstop panel seat 17 and rear conveyer jack 14, can regulate chucking power by regulating rear conveyer jack 14, in the present embodiment, backstop panel seat 17 is L-type substantially, be understandable that, it can be also other suitable shape, as long as it can fixed clamp live chute 11.Chute 11 is case type structures, be provided with hydraulic jack 15 on its base plate, in chute 11, the top of hydraulic jack 15 is provided with scraper plate 13, scraper plate 13 can move along the length direction of chute 11, in the present embodiment, scraper plate 13 is divided into two-layer, both sides connect the sidewall of chute 11 by sprocket wheel 16, length direction loopy moving in the mode of belt-like machine along chute 11, a plurality of scraper plate circular holes 12 preferably are set on scraper plate 13, the slightly larger in diameter of circular hole gets final product in the diameter of the jack bar of hydraulic jack 15, facilitate it to stretch out, situation about not routing up from chute 11 with the filling material pocket of avoiding thrust to cause not, hydraulic jack 15 is arranged in the part of inclined to one side holder orientation of chute 11, be beneficial to filling material pocket top to goaf, hydraulic jack 15 is connected with the electromagnetic valve on the filling hydraulic support by high-pressure oil pipe 7, by stretching of solenoid control hydraulic jack 15.
In use, can adjust by the angle of regulating back screen baffle plate 10 size of supporting and space.When needs carry out filling, tune up the angle of back screen baffle plate 10, make it can hold chute 11; Drive scraper plate 13 to move, the drive filler moves to treats the filling position; Stop scraper plate 13 and move, start hydraulic jack 15, filler is ejected to chute 11, fall in goaf; Repeat above-mentioned steps, until goaf filling is complete.
The above; it is only the preferably specific embodiment of patent of the present invention; but the protection domain of patent of the present invention is not limited to this; anyly be familiar with in technical scope that those skilled in the art disclose in patent of the present invention; the variation that can expect easily or replacement, within all should being encompassed in the protection domain of patent of the present invention.
