Description

A kind of filling hydraulic support with automatic bag overturning machine structure
Technical field
The utility model relates to a kind of filling hydraulic support, relates in particular to a kind of hydraulic support that the work plane goaf is carried out having of filling of automatic bag overturning machine structure that is applicable to.
Background technology
Hydraulic support is the key equipment of comprehensive mechanical coal mining, almost in the mine in each colliery, all need use.Common hydraulic support is to design for common work plane digging at present; Its rear portion supporting and space is less, can not carry out big step pitch shielding function with adopting with the breaking roof that emits to 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 makes it fall into the goaf through turning over bag manually, and this filling method is not only wasted time and energy; Also cause danger easily, influenced the safety in production in colliery greatly.
The utility model content
The utility model provides a kind of hydraulic support that big step pitch is screened, turned over bag bashing automatically that has to defective of the prior art.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 the drag conveyor that turns over bag function with having of rear portion of shielding; Carry drag conveyor the fillers such as gangue of the one-tenth bag of coming to be turned in the goaf, reach the purpose of bashing.
The technical scheme of the utility model is following:
A kind of filling hydraulic support with automatic bag overturning machine structure; Comprise column, back timber and base, said column is fixedly connected said back timber and said base, an end of the hinged back screen baffle plate in the rear end of said back timber; The other end of said back screen baffle plate is a free end; Said back screen baffle plate can be around itself and the rotation of the pin joint of said back timber under the driving of back hydraulic jack, and said base is provided with the back conveyer jack of lateral arrangement, and the rear end of said base is connected with the backstop panel seat; Be provided with chute between said conveyer jack and the said backstop panel seat; The base plate of said chute is provided with hydraulic jack, is provided with scraper plate in the said chute, and said scraper plate can move relative to chute.
Said scraper plate is provided with the scraper plate circular hole.
Said hydraulic jack is arranged in the part of inclined to one side holder orientation of said chute
Said hydraulic jack is connected with electromagnetic valve on the said filling hydraulic support through high-pressure oil pipe.
The beneficial effect of the utility model is: under the condition that can guarantee hydraulic support stability, satisfy the needs that bag is turned in goaf filling automatically.The described hydraulic support of the utility model is when mining; Long back screen baffle plate is positioned on the same horizontal plane stretching out under the effect of hydraulic cylinder with back timber; Active support filling area breaking roof, the drag conveyor to the hydraulic support rear plays fine protective effect simultaneously.
Description of drawings
Accompanying drawing 1 is the said structural representation with filling hydraulic support of automatic bag overturning machine structure of the utility model.
Reference numeral is following:
The 1-coal-winning machine; The 2-drag conveyor; The 3-extensible canopy; Hydraulic jack before the 4-; The 5-back timber; The 6-column; The 7-high-pressure oil pipe; The 8-base; Hydraulic jack behind the 9-; 10-back screen baffle plate; The 11-chute; 12-scraper plate circular hole; The 13-scraper plate; Conveyer jack behind the 14-; The 15-hydraulic jack; The 16-sprocket wheel; 17-backstop panel seat.
The specific embodiment
Referring to accompanying drawing 1, have the filling hydraulic support of automatic bag overturning machine structure, the place ahead of filling hydraulic support is extractive equipments such as coal-winning machine, drag conveyor; Support comprises column, back timber and base, and the front end of back timber is connected with extensible canopy, and extensible canopy is driven by preceding hydraulic jack; The rear end of back timber is hinged with the back screen baffle plate, and the other end of back screen baffle plate is the free end that is not connected contact with other parts, also is connected with a back hydraulic jack between back screen baffle plate and the back timber; It can rotate around the pin joint with back timber under the driving of back hydraulic jack, thus the supporting and space of regulating filling hydraulic pressure back-end support, and the middle part of base is provided with back conveyer jack; Back conveyer jack lateral arrangement, the direction of jack bar is towards the rear end of filling hydraulic support, and the rear portion of base is connected with the backstop panel seat; The jack bar clamping chute of backstop panel seat and back conveyer jack can be regulated chucking power through regulating back conveyer jack, in the present embodiment; The backstop panel seat is the L type basically; It it is understandable that it also can be other suitable shape, as long as can fixed clamp live chute.Chute is a case type structures, and its base plate is provided with hydraulic jack, and the top of hydraulic jack is provided with scraper plate in the chute; Scraper plate can move along the length direction of chute, and in the present embodiment, scraper plate is divided into two-layer; Both sides are through the sidewall of sprocket wheel connection chute, and are mobile along the length direction circulation of chute with the mode of belt-like machine, and a plurality of scraper plate circular holes preferably are set on scraper plate; The somewhat larger in diameter of circular hole gets final product in the diameter of the jack bar of hydraulic jack, makes things convenient for it to stretch out, situation about from chute, not routing up with the filling material pocket of avoiding thrust to cause inadequately; Hydraulic jack is arranged in the part of inclined to one side holder orientation of chute; Be beneficial to filling material pocket top to the goaf, hydraulic jack is connected with electromagnetic valve on the filling hydraulic support through high-pressure oil pipe, through stretching of solenoid control hydraulic jack.
In use, can adjust the size of supporting and space through the angle of regulating the back screen baffle plate.When needs carry out filling, transfer the angle of big back screen baffle plate, make it can hold chute; The driving scraper plate moves, and the drive filler moves to treats the filling position; Stop scraper plate and move, start hydraulic jack, filler is ejected chute, fall in the goaf; Repeat above-mentioned steps, finish up to goaf filling.
The above; Be merely the preferable specific embodiment of the utility model patent; But the protection domain of the utility model patent is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model patent discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model patent.
