Abstract

A kind of coal mine filling transversal end hydraulic support, belongs to the 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 root supporting top beam, guide rod is had between base and back timber, be hinged with division board in the front end of back timber, be hinged with side plate in division board both sides, in division board lower end, be inserted with expansion plate; At the hinged advancing jack of pan frontward end, lift end jack base rear end is hinged; Swing jack one end and back timber hinged, the swing jack other end and upper division board hinged; Be provided with pack hole in division board, conveyance conduit is through pack hole.Advantage: can mechanically realize isolating fast the upper and lower termination of coal-face, improves filling efficiency of isolation.In filling coal mining, the upper and lower terminal outlet in quick isolating seal coal-face district to be filled, cancels the work of manually building isolation template, reduces hand labor.

Description

A kind of coal mine filling transversal end hydraulic support

Technical field

The utility model relates to a kind of hydraulic support of filling coal mining, particularly a kind of coal mine filling 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.

Utility model content

In order to solve the problems of the technologies described above, of the present utility model is to provide a kind of coal mine filling transversal end hydraulic support, the isolation operation of upper and lower termination, district to be filled is exploited for coal mine paste filling, preparation mechanization degree is isolated not high, the problem of inefficiency in solution coal mine paste filling production technique.

The purpose of this utility model is that sample realizes: this end hydraulic support comprises: back timber, base, hydraulic pressure support column, guide rod, advancing jack, division board, side plate, lift end jack, expansion plate and swing jack; Be connected with guide rod between back timber with base and be provided with the hydraulic pressure support column of root supporting top beam, guide rod is had between base and back timber, division board is hinged with in the front end of back timber, side plate is hinged with in division board both sides, expansion plate is inserted with in division board lower end, expansion plate can move up and down by division board relatively, realizes base plate isolation features; At the hinged advancing jack of pan frontward end, lift end jack base rear end is hinged; 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; Be provided with pack hole in division board, conveyance conduit through pack hole, and carries out paste body filling to the filling space that coal-face is formed.

Described back timber upper surface has projection, and there is filling bag hanging ring back timber front end, and back timber rear ends has earhole respectively.

Beneficial effect: owing to adopting such scheme, back timber is hinged with division board, division board hinged side, according to filling coal mining work plane direction, division board can be hinged on back timber front end or top beam rear end and middle filling hydraulic support and form filling fast and isolate barricade, meets packing job requirement.Be 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, open side plate, separately be aided with and seal ancillary method on a small quantity, can realize the upper and lower end seals of coal work during gob side entry retaining, solve in coal mine paste filling production technique that to isolate preparation mechanization degree not high, the problem of inefficiency, 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 upper and lower terminal outlet in quick isolating seal coal-face district to be filled, cancels the work of manually building isolation template, reduces hand labor, improves filling integral operating efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 3 is the schematic top plan view of Fig. 1.

In figure, 1, back timber 1; 2, base; 3, hydraulic pressure support column; 4, guide rod; 5, advancing jack; 6, division board; 7, side plate; 8, end jack is lifted; 9, expansion plate; 10, jack is swung.

Detailed description of the invention

The utility model is top spacer assembly, comprise back timber 1, base 2, end hydraulic support support post 3, guide rod 4, advancing jack 5, division board 6, side plate 7, lift end jack 8, expansion plate 9, swing jack 10; Be connected with guide rod between back timber 1 with base 2 and be provided with the hydraulic pressure support column 3 of 4 supporting top beams, guide rod 4 is had between base 2 and back timber 1, be hinged with division board 6 in the front end of back timber 1, be hinged with side plate 7 in division board 6 both sides, in division board 6 lower end, be inserted with expansion plate 9.At the hinged advancing jack 5 in base 2 front end, lift end jack 8 base 2 rear end is hinged; Expansion plate 9 is equipped with in division board 6 lower end, and expansion plate 9 can move up and down by division board 6 relatively, realizes base plate isolation features; Swing jack 10 one end and back timber 1 hinged, swing jack 10 other end hinged with upper division board 6, adjust angle adaptation different operating condition.Be provided with the pack hole 11 of filling in division board 6, paste body filling is carried out in the filling space that conveyance conduit is formed to coal-face by pack hole 11.

This coal mine work area filling end hydraulic support, utilizes division board 6, expansion plate 9 and side plate 7, and division board 6 is hinged on back timber 1 front end, and side plate 7 is opened the middle filling hydraulic support with coal-face and formed work plane lower end isolating seal working space; Division board 6 is hinged on back timber 1 rear end, and side plate 7 is opened the middle filling hydraulic support with coal-face and formed work plane upper end isolating seal space; Utilize the expansion plate 9 be arranged in division board 6 lower end, along with the length of the change regulating fender of face end support height.

Described back timber upper surface has projection, and there is filling bag hanging ring back timber front end, and back timber rear ends has earhole respectively.
