Description
Technical field
The utility model relates to the airtight device for filling of a kind of mobile hydraulic, belongs to coal mining filling field, is applicable to the filling of high-water material.
Background technology
At present, the coal-mining method in field of coal mining, the mode of handling by the goaf can be divided into: three kinds of caving method, coal column method and filling methods.Wherein, the method for collecting coal by the means of filling is meant in the exploitation process of work plane or after the exploitation, adopts the relatively inexpensive filler coal-mining method that goaf filling is closely knit.Its purpose mainly is to utilize obturation that country rock is controlled, to reduce ecology and geological disasters such as ground settlement and base plate gushing water.Simultaneously, create safer operating condition for stope.Using high-water material to carry out in the technology of filling mining,, need carry out airtight the open goaf of intending filling because high-water material has stronger flowability.To the goaf in the methods such as laneway type filling mining, strip-type filling mining, wall type filling mining, what usually adopt is the coal column wall, build brick wall or mould three kinds of modes such as compiling bag and carry out airtight.The subject matter that these three kinds of modes exist is that resource recovery is low, production efficiency is low, pack effectiveness is low.But up to now, also there is not good method can substitute aforesaid way.
The utility model content
According to above deficiency of the prior art; The technical problem that the utility model will solve is: a kind of filling good sealing effect is provided, cost is low and can improves the airtight device for filling of mobile hydraulic of pack effectiveness, be particularly useful for that high-water material is realized continuously at fully-mechanized mining working, efficient filling.
The utility model solves the technical scheme that its technical problem adopted: the airtight device for filling of described mobile hydraulic; Some groups of hydraulic supports that comprise parallel arranged; It is characterized in that: the rear end of every group of hydraulic support connects the vertical barricade of hard plate material through crossbeam; On the hydraulic support respectively through gripper shoe be installed with upper and lower two each other back to hydraulic cylinder, the piston rod top secured adjusted plate of hydraulic cylinder, adjustable plate comprise perpendicular to a horizontal pressure foot of piston rod be welded on the horizontal pressure foot two ends and be parallel to two vertical plates of piston rod; Horizontal pressure foot is fixed on the piston rod top; Vertical plate is positioned at the inboard of vertical barricade, and the outside of some vertical barricades is provided with the holistic waterproof door curtain made of cloth, and the upper/lower terminal of the door curtain made of cloth is walked around upper and lower horizontal pressure foot respectively and is connected with gripper shoe through regulating spring; The top of the horizontal pressure foot top door curtain made of cloth is provided with the high polymer elastic sealing block, and sealing block is connected with the door curtain made of cloth through positioner.
Wherein, positioner can be securing members such as bolt, and the utility model adopts following preferred version:
Described positioner comprises cylinder, bolt and packing ring; Cylinder and packing ring are separately positioned on the upper and lower of the door curtain made of cloth; Cylinder inside is provided with the screw that cooperates with bolt; Bolt passes packing ring, the door curtain made of cloth and is threaded with cylinder, and the corresponding circle cylinder is provided with detent in the bottom of sealing block, and cylinder is arranged in detent.Before packing job, especially behind the conversion workspace, need confirm the length of the door curtain made of cloth according to workspace situation (position of top board, base plate), through positioner the door curtain made of cloth and sealing block are located then.But because in same workspace, the distance between roof, the base plate is more or less the same, therefore, in the packing job process of same workspace, the length that generally need not regulate the door curtain made of cloth.
The left and right sides, top of described horizontal pressure foot is provided with deflector roll, and the door curtain made of cloth is walked around from two deflector rolls.Through deflector roll can reduce the horizontal pressure foot and the door curtain made of cloth between friction, thereby the door curtain made of cloth is played protective action, prolong the application life of the door curtain made of cloth.
The described door curtain made of cloth is PVC Polypropylence Sheet, nonwoven or rubberized fabric.The door curtain made of cloth through integral body stops the slit between the adjacent vertical barricade, the sealing effectiveness when guaranteeing filling.
Described hard plate material is a kind of of high molecular weight polyethylene board material, irony sheet material or wooden boards.
Described sealing block is block rubber or elastic polyurethane piece, and the contact surface of adjacent seals piece is a lozenges.Can guarantee the sealing between the adjacent seals piece through lozenges, improve the sealing effectiveness of filling.
During work; The front end of hydraulic support is parallel to coal-face, and need confirm mutually the quantity of hydraulic support side by side according to the width of coal-face, makes the vertical barricade of some groups of hydraulic support rear ends form the vertical barricade of one side filling jointly and seals with the slit between the adjacent vertical barricade of the door curtain made of cloth; Regulate the displacement of upper and lower two adjustable plates and two sealing blocks simultaneously through hydraulic cylinder; Sealing block is closely contacted with top board, base plate, guarantee the sealing between vertical barricade and top board, the base plate, then high-water expansion filling material is filled into vertical barricade and in the confined space between the filling area (that is: wait to fill district); After treating that high-water expansion filling material solidifies; Coal-winning machine continues exploitation along coal-face, exploit a segment distance after (this distance be no more than stride for the first time apart from), some groups of hydraulic supports move to coal-face with coal-winning machine simultaneously; Repeat above-mentioned filling action then, filling while exploiting.
Except above-mentioned points, upper and lower two hydraulic cylinders also can substitute with the double end hydraulic jack, control the up-down of two sealing blocks through the two-piston bar of double end hydraulic jack.
The beneficial effect that the utility model had is:
The airtight device for filling of this mobile hydraulic directly adopts the vertical barricade of hydraulic support rear end as the vertical barricade of filling; Need not the extra vertical barricade of building by laying bricks or stones; Therefore saved the labour's (build vertical barricade by laying bricks or stones or hang bag) in traditional stowing operation, reduced cost and improved pack effectiveness; Because top board and base plate are uneven, regulate the displacement of upper and lower two sealing blocks through hydraulic cylinder, sealing block is closely contacted, the sealing of vertical barricade and top board, base plate during with the assurance filling with top board, base plate; The door curtain made of cloth through integral body stops the slit between the adjacent vertical barricade, and the sealing effectiveness when both guaranteeing filling is avoided pollution and the infringement of filling slurry to vertical barricade again; Guarantee mode, country rock is moved the better controlled effect of playing, thereby roof caving and ground settlement are played the good restraining effect through filling while exploiting.
