Abstract
The utility model discloses a top isolating device for a coal mine filling bracket, belonging to an isolating device for a filling coal mining bracket. The top isolating device comprises a top beam, a sealing strip, diagonal jack, an upper telescopic box, an upward extension jacket and an isolating plate, wherein the sealing strip is arranged on the top of the upper telescopic box; the upper telescopic box is arranged on the top of the isolating plate; one end of the upward extension jack is hinged to the upper telescopic box, and the other end of the upward extension jack is hinged to the upper isolating plate; the isolating plate is hinged to the tail of the top beam; one end of the diagonal jack is hinged to the isolating plate, and the other end of the diagonal jack is hinged to the top beam. By adopting the top isolating device, the gap between the top beam of the sealing bracket and a top plate can be sealed effectively, a filling isolating barrier wall can be formed rapidly, the filling isolating effect is ensured, and the filling operation requirement is met. The top isolating device is suitable for various paste filling working faces. Filling isolation can be performed mechanically in filling coal mining, effective seal of the isolating plate is ensured, filling paste is prevented from flowing into the working face, the filling preparation working time is shortened effectively, labor work is reduced, and the overall paste filling efficiency is increased.
Description
Technical field
The utility model relates to a kind of spacer assembly of filling coal mining support, particularly a kind of top spacer assembly of coal mine paste filling support.
Background technology
Paste body filling technology is as one of Green Technique in Coal Mining system, and its main purpose is to solve " three next on " to press coal, improves colliery resource recovery ratio, extends mine service-life.
At present, the isolation leak stopping problem for the treatment of filling area is one of Major Difficulties of restriction exhibition paste body filling production technique.Isolate leak stopping work if adopt merely manual type, not only complex operation, labor strength is large, and length consuming time, efficiency is low, and traditional fully mechanized mining supporter is not provided with the spacer assembly of sealing filling slurry, need to adopt equally manual type to build isolation barricade, mechanization degree is low, seriously restricts the raising of paste body filling coal mining efficiency.Therefore, in paste body filling production technique, isolate preparation mechanization degree not high, inefficiency, while there is colliery backfill, sealing problem between support and top board, becomes those skilled in the art's problem demanding prompt solution.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of top spacer assembly of coal mine paste filling support, solves in the time of the backfill of colliery sealing problem between support and top board.
The purpose of this utility model be achieved in that this spacer assembly comprise back timber, weather strip, oblique pull jack, upper expansion box, on stretch jack and division board; Weather strip is arranged on expansion box top; Expansion box is equipped with at division board top; On stretch jack one end and upper expansion box is hinged, above stretch the jack other end and upper division board is hinged; Division board and back timber afterbody are hinged; Oblique pull jack one end and division board are hinged, and the other end and back timber 1 are hinged.
Upper expansion box is box-structure, or frame construction.
Division board is box-structure, or frame construction.
Weather strip is that the flexible material of flame-retardant and anti-static is made.
Beneficial effect, owing to adopting such scheme, in the time carrying out filling isolation preparation, only need stretch out expansion box 4, be separately aided with a small amount of sealing ancillary method, can realize the sealing between support bracket at tail part and back timber, can mechanically realize the sealing to set cap and top board gap, effective sealing set cap and top board gap, form filling isolation barricade fast, guarantee filling isolation effect, meet packing job requirement.Be applicable to various paste body filling work planes.Can, in filling coal mining, in mechanization mode, filling isolation be set, guarantee division board effective sealing, prevent that fill paste from flowing into work plane, effectively shorten the filling preparation time, reduce hand labor, improve paste body filling whole work efficiency.Solve in the time of the backfill of colliery sealing problem between support and top board, reached the utility model object.
Advantage: in filling coal mining, fast sealing set cap and top board gap, cancel workman and manually build the work of isolating template, reduces hand labor, improves filling integral operating efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model side-looking structure chart.
In figure: 1, back timber; 2, weather strip; 3, oblique pull jack; 4, upper expansion box; 5, on, stretch jack; 6, division board.
The specific embodiment
Embodiment 1: this spacer assembly comprise back timber 1, weather strip 2, oblique pull jack 3, upper expansion box 4, on stretch jack 5 and division board 6; Weather strip 2 is arranged on expansion box 4 tops; Expansion box 4 is equipped with at division board 6 tops, and upper expansion box 4 relatively division board 6 moves up and down, and object is that crush seal bar 2 is realized top seal function.
On stretch jack 5 one end and upper expansion box 4 hinged, above stretch jack 5 other ends and upper division board 6 hinged; Division board 6 is hinged with back timber 1 afterbody; Oblique pull jack 3 one end and division board 6 are hinged, and described oblique pull jack 3 other ends and back timber 1 are hinged, and division board 6 can be with respect to back timber 1 swing, and object is to adjust angle to adapt to different operating condition.
Division board 6 is box-structures, or frame construction.
Top of the present utility model spacer assembly, its specific embodiment is:
The realization of top board isolating seal function: when sealing preparation completes, carry out before filling operation, make division board 6 in suitable duty by operation oblique pull jack 3, then operation on stretch jack 5 by 4 liters of upper expansion boxs until top weather strip 2 contacts and pushes top board, realize top seal function with this.
