Abstract
A kind of coal mine filling exploitation gob side entry retaining transversal end hydraulic support, belongs to the horizontal type hydraulic support of filling coal mining.The back timber of this end hydraulic support is connected with guide rod with between base and is provided with the hydraulic pressure support column of supporting top beam, and hinged guide rod between base and back timber, is hinged with division board in the leading section of back timber, in division board lower end, be inserted with expansion plate; Division board is equipped with side direction stretch; Swing jack one end and back timber hinged, swing the jack other end and upper division board hinged, for adjusting angle adaptation different operating condition.Advantage: can mechanically realize isolating fast the upper and lower termination of coal-face, improves filling efficiency of isolation.In filling coal mining, the lower end outlet of quick isolating seal coal-face district to be filled, the outlet of different size filling area and cross-section shape of roadway can be adapted to by multi rack combination, do not destroy original roadway support, cancel the work of manually building isolation template, reduce hand labor, improve filling integral operating efficiency.
Description
Technical field
The utility model relates to a kind of horizontal type hydraulic support of filling coal mining, particularly a kind of coal mine filling exploitation gob side entry retaining transversal end hydraulic support.
Background technology
Paste body filling technology is as one of Green Technique in Coal Mining system, and its main purpose solves " three next on " pressure coal, improves coal resource recovery ratio, extend mine service-life.
At present, the isolation Lost circulation problems in district to be filled is one of Major Difficulties of restriction exhibition paste body filling production technique.If manual type is adopted to carry out isolation plugging operation simple, 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, needs equally to adopt manual type to build isolation barricade, mechanization degree is low, the raising of serious restriction coal mine paste filling coal mining efficiency.
Therefore, it is not high to isolate preparation mechanization degree in paste body filling production technique, and inefficiency, 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 purpose of this utility model to provide a kind of coal mine filling to exploit gob side entry retaining transversal end hydraulic support, solves the upper and lower termination isolation speed of the district to be filled when coal mine filling slow, unsafe problem.
The purpose of this utility model is achieved in that this end hydraulic support comprises: back timber, base, hydraulic pressure support column, guide rod, swing jack, division board, expansion plate and side direction are flexible; Be connected with guide rod between back timber with base and be provided with the hydraulic pressure support column of root supporting top beam, lower end of the guide rod is welded on base, guide rod and hydraulic pressure support column and top beam ear seat hinged.
Be hinged with division board in the leading section of back timber, in division board lower end, be inserted with expansion plate; Division board is equipped with side direction stretch; Expansion plate can move up and down by division board relatively, realizes base plate isolation features; Swing jack one end and back timber hinged, swing the jack other end and division board hinged, for adjusting angle adaptation different operating condition.
Described division board is box-structure or frame construction; Described expansion plate is box-structure or frame construction; Described side direction expansion plate is box-structure or frame construction.
Beneficial effect: owing to adopting such scheme, back timber is hinged with division board, division board is equipped with side direction and stretches and downside interpolation expansion plate, guide rod is bracket stable mechanism, hydraulic pressure support column is positioned at guide rod and reduces back timber width, to adapt to array pitch between roadway bolt, guarantees that roadway support is not destroyed.Multi rack holder combination and middle filling hydraulic support form filling fast and isolate barricade, meet packing job requirement, are applicable to gob side entry retaining paste body filling work plane.In filling coal mining, filling isolation can be set with mechanized manner, ensure division board effective sealing, prevent fill paste from flowing into work plane, effectively shorten the filling preparation time, reduce hand labor, improve paste body filling whole work efficiency.
When carrying out filling isolation preparation, only expansion plate need be stretched out, opening side is to flexible, separately be aided with and seal ancillary method on a small quantity, can realize coal-face lower end isolating seal during gob side entry retaining, it is slow that the program solves the upper and lower termination isolation speed of the district to be filled when coal mine filling, and unsafe problems, reaches the utility model object.
Advantage: can mechanically realize isolating fast the upper and lower termination of coal-face, improves filling efficiency of isolation.In filling coal mining, the lower end outlet of quick isolating seal coal-face district to be filled, the outlet of different size filling area and cross-section shape of roadway can be adapted to by multi rack combination, do not destroy original roadway support, cancel the work of manually building isolation template, reduce hand labor, improve filling integral operating efficiency.

Detailed description of the invention
The utility model is the top spacer assembly that paste body filling is mined, and end hydraulic support comprises: back timber 1, base 2, hydraulic pressure support column 3, guide rod 4, swing jack 5, division board 6, expansion plate 7 and side direction flexible 8; Be connected with guide rod 4 between back timber 1 with base 2 and be provided with the hydraulic pressure support column 3 of 2 supporting top beams, guide rod 4 lower end is welded on base 2, guide rod 4 and hydraulic pressure support column 3 and top beam ear seat 101 hinged.
Be hinged with division board 6 in the leading section of back timber 1, in division board 6 lower end, be inserted with expansion plate 7; Division board 6 is equipped with side direction flexible 8; Expansion plate 7 can move up and down by division board 6 relatively, realizes base plate isolation features; Swing jack 5 one end and back timber 1 hinged, swing jack 5 other end and upper division board 6 hinged, for adjusting angle adaptation different operating condition.
Described division board 6 is box-structure or frame construction; Described expansion plate 7 is box-structure or frame construction; Described side direction expansion plate 8 is box-structure or frame construction.
This coal mine work area filling end hydraulic support, utilize division board 6, expansion plate 7 and side direction flexible 8, division board 6 is hinged on back timber 1 front end, and side direction flexible 8 is opened and formed work plane lower end isolating seal working space with this type end hydraulic support and the middle filling hydraulic support of coal-face; Utilize the expansion plate 7 be arranged in division board 6 lower end, along with the length of the change regulating fender of face end support height; Multi rack combination can adapt to filling outlet size.
