Abstract
The utility model discloses a pushing and tamping device specially for an end filling hydraulic support, and relates to an accessory part of a hydraulic support. The pushing and tamping device comprises an upper swinging beam, wherein the right end of the upper swinging beam is provided with a shovel board while the left end of the upper swinging beam is hinged with a rear tail beam of the end filling hydraulic support through a fixing ear plate and also hinged with a piston rod of a pull oil cylinder through a pull ear plate; and a cylinder body of the pull oil cylinder is also hinged on the rear tail beam of the end filling hydraulic support. Through stretch out and draw back of the pull oil cylinder, the upper swinging beam hinged on the rear tail beam of the end filling hydraulic support can be driven to swing up and down, and therefore falling filling materials can be pushed to the top of a gob so as to fill and tamp the gob.
Description
Technical field
The utility model relates to a kind of appurtenances of hydraulic support, the special-purpose ramming device of passing of especially a kind of termination filling hydraulic support.
Background technology
Along with the fast development of Chinese national economy, every profession and trade strengthens the demand of coal year by year, and " three times " (under building, under the railway, under the water body) presses the problem of coal to restrict the development of many old mines.Jizhong Energy Co., Ltd.'s Xingtai Coal Mine presses the building in the coal to press down the coal problem in order to solve mine main " three times ", studies and designed down-hole coal excavation work plane spoil and flyash filling mining technology and technology.This placement method is to the goaf filling material after the down-hole coal excavation work plane has been adopted coal; Be full of whole goaf; And the material of filling exerted pressure and reach certain intensity; To produce the effect of roof supporting, can the surface subsidence amount in goaf be controlled in the safe scope, the protection surface buildings is not damaged.
The source of attal is the washing spoil of coal separation plant and the flyash of power plant.Attal is behind aboveground arrival down-hole; Through conveyor spoil and flyash are transported on the automatic moving type reprinting conveyor in coal-face fortune cash lane; Reprint hanging on the conveyer on the tail boom behind the filling hydraulic support through it; To goaf transportation spoil and flyash, each joint trough of hanging conveyer all has blanking port, can be through these blanking ports to the rear portion of filling hydraulic support attal.All there is a scalable balance arm at the rear portion of each hydraulic support; Can realize stretching and swinging up and down through hydraulic jack; Drive the anterior passing shovel of balance arm and push the fill material that falls to goaf, the effect of playing roof supporting of tamping is filled up in the goaf through pushing away several times to smash.
Because the conveyer that tail boom is hung behind the filling hydraulic support adopts two kinds of drive; The all dynamic transmission device of head and drive end unit; Actuating unit comprises motor, reductor, headstock, lead-over groove etc.; Because the width of actuating unit and aspect ratio middle part blowpit are a lot of greatly; The position of ramming mechanism is in the bottom of hanging conveyer, and the upwards oscillating quantity of the balance arm mechanism of here installing receives very big restriction, therefore can not realize the very big function of the amplitude that swings up and down that common balance arm mechanism is reached at two end hydraulic support rear portions at the head of the work plane of mounting power driving device and tail place; Also just can't tamping be filled up in the goaf at this place, influence filling effect.
The utility model content
The technical problem that the utility model will solve provides the special-purpose ramming device of passing of a kind of termination filling hydraulic support, fills up tamping with the goaf that will locate, guarantees filling effect.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
The special-purpose ramming device of passing of a kind of termination filling hydraulic support; Comprise balance arm; The right-hand member of last balance arm is provided with the shovel plate; Left end is hinged through the back tail boom of fixing otic placode and termination filling hydraulic support, moves otic placode and draws the piston rod that moves oil cylinder hinged through drawing again, draws the cylinder body that moves oil cylinder also to be articulated on the back tail boom of termination filling hydraulic support.
Last balance arm comprises the balance arm body, and can in the balance arm body, stretch out the extensible canopy that moves with retraction, between balance arm body and extensible canopy, is provided with telescopic oil cylinder, and the shovel plate is arranged at the right-hand member of extensible canopy, draws and moves the left end that otic placode is arranged at the balance arm body.
Adopt the beneficial effect that technique scheme produced to be: to move the flexible of oil cylinder through drawing; Can drive last balance arm on the back tail boom that is articulated in termination filling hydraulic support does and swings up and down; Thereby can pass fallen attal to the top in goaf, fill up tamping to the goaf; The goaf material tamping of being more convenient for of the stretching structure of last balance arm.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the termination filling hydraulic rack structure sketch map that has the utility model;
Fig. 2 is the structural representation of the utility model.
Wherein, 1-shovel plate; 2-is otic placode fixedly; Tail boom behind the 3-; 4-draws and moves otic placode; 5-draws and moves oil cylinder; 6-balance arm body; The 7-extensible canopy; The 8-telescopic oil cylinder; 9-termination filling hydraulic support; The last balance arm of 10-.
The specific embodiment
The utility model comprises balance arm 10; The right-hand member of last balance arm 10 is provided with shovel plate 1; Fixedly otic placode 2 is hinged with the back tail boom 3 of termination filling hydraulic support 9 through four for left end; Draw through two again and move otic placode 4 and two and draw the piston rod that moves oil cylinder 5 hinged, two are drawn on the back tail boom that the cylinder body that moves oil cylinder 5 also is articulated in termination filling hydraulic support 93.
Draw two of moving balance arm body 6 that oil cylinder 5 control goes up balance arm 10 to draw through two and move otic placode 4; Make to go up balance arm 10 behind itself and the filling hydraulic support tail boom 3 fixedly the jointed shaft between the otic placode 2 be rotated; So just can rotate to horizontal level from vertical position, material pushed away the top of smashing the goaf through shovel plate 1 with going up balance arm 10.Last balance arm 10 in this device is telescopic frame constructions, is provided with two telescopic oil cylinders 8 in the framework, can with the shovel plate 1 stretch be inserted into push away in the material of smashing, thereby can easily attal be scooped up, push away and smash the top, goaf.
