Abstract
The combined support consists of alternate top beams comprising front beam and back beam, the front beam is the middle beam and the back beam is the left and right beams. The front beam is connected with the single hydraulic prop 1 and the prop 2 to form a front support, and the rear beam is connected with the single hydraulic prop 3 and the prop 4 to form a rear support. The front and rear supports need to be moved by special light support moving jacks, and can also be pushed and pulled directly by manpower. The support has the advantages of large support area, high support efficiency, good safety and convenient movement during use, and is an ideal mine support facility.
Description
The utility model relates to a kind of supporting facility of a kind of colliery high-grade common coal mining face, particularly a kind of alternately back timber sectional shelf-unit.
Present articulated roof beam, the miner must dismantle repeatedly, carry in advance working links such as sky, caving, supports beam column, bears powerful labour intensity, uses this articulated roof beam, and mechanization degree is low, and production efficiency is low, poor stability.
Task of the present utility model is to design a kind of alternately back timber sectional shelf-unit, replaces articulated roof beam, in order to overcome the deficiency of articulated roof beam when the maintenance work face top board.
Task of the present utility model can reach by following proposal:
The utility model is by alternately back timber and hydraulic prop combine.Alternately back timber is made up of the front-axle beam and the back rest again, and front-axle beam is middle beam, and the back rest is the beam of the right and left.The planform of front and rear beam is identical, is i-shaped roof beam, and as road rail steel shape, paste and is welded with the plate muscle at groove place in both sides, and the termination face is welded with connector.The back rest is provided with two pairs of pulley gears, is clipped in the both sides groove of front-axle beam, its objective is to play holder, the forward and backward beam body of frame and slip effect when moving forward and backward beam.Front-axle beam and hydraulic prop

2Connect and constitute fore-stock; The back rest and hydraulic prop
3And pillar
4Connect and constitute after-poppet.Pillar
4Be two individual props, UNICOM's oil pipe is arranged in the middle of it.Move forward and backward support and need use the special-purpose light-duty frame jack that moves, also available artificial directly push-and-pull, first three the root hydraulic prop in the support
1, pillar
2, pillar
3Strut angle need be designed to and can in 1-7 ° of scope, adjust, back two pillars
4Should in 1-100 °, adjust support angle according to the concrete condition of supporting roof.
The utility model has the advantages that: Area of bearing is big, the supporting efficiency height, and safety is good, uses this support to move, support, caving convenience, labour intensity is little, the mechanization degree height, and it is simple in structure, make easily, installation, easy to operate is a kind of desirable mining supporting facility.
Below in conjunction with accompanying drawing the utility model is done detailed description further.
Fig. 1 is the upper half overall structure front view;
Fig. 2 is following half overall structure front view;
Fig. 3 is the upper half left view;
Fig. 4 is following half left view;
Fig. 5 is the A-A sectional view.
As Fig. 1-5, alternately back timber is made up of the front-axle beam (1) and the back rest (4), and front-axle beam (1) is middle beam, and the back rest (4) is the beam of the right and left.An assembly front-axle beam (1) is one, and the back rest (4) is two, and front-axle beam (1) is identical with the planform of the back rest (4), and just size is distinguished to some extent, and two beams are i-shaped roof beam, as road rail steel shape.Paste and be welded with the plate muscle at front-axle beam (1) and groove place, the back rest (4) both sides, and the termination face is welded with connector.The back rest (4) is provided with two pairs of pulley gears, is clipped in the both sides groove of front-axle beam (1), plays the beam body and the slip effect of holder, frame front-axle beam (1), the back rest (4) when its objective is mobile front-axle beam (1), the back rest (4).Front-axle beam (1) and hydraulic prop
1(2) and pillar
2(3) connect the formation fore-stock; The back rest (4) and hydraulic prop
3(5) and pillar
4(6) connect the formation after-poppet.Pillar
4(6) be two individual props, two pillars
4UNICOM's oil pipe is arranged (6).Move forward and backward support and need use the special-purpose light-duty frame jack (7) that moves of auxiliary tool, also available artificial directly push-and-pull, first three the root hydraulic prop in the support
1(2), pillar
2(3), pillar
3(5) strut angle need be designed to and can adjust in 1-7 ° of scope, back two pillars
4(6) should in 1-100 °, adjust support angle according to the concrete condition of supporting roof.
The utility model is steelwork.
During use, support need be moved forward, two hydraulic props on the fore-stock should be shed earlier
1(2) and pillar
2(3) load is supported on hydraulic prop with the special-purpose light-duty frame jack (7) that moves of auxiliary tool
1(2) and pillar
3(5) pressurization promotes fore-stock between, also available artificial directly push-and-pull.Be pushed into the coal cutting degree of depth, support fore-stock.Be supported on hydraulic prop with jack (7) equally during mobile after-poppet
3(5) and pillar
2(3) after-poppet is passed in pressurization between, or with artificial directly push-and-pull after-poppet in the position of mining technology requirement.Also can first mobile after-poppet, move forward fore-stock again.Concrete use will be determined the order of mobile front and back support and the post distance between support according to the mining requirement and the distance of face roof under control.Hydraulic single prop in the duty
3(5) can add the support force of skewback reinforcement on the column cap to front-axle beam (1).Front-axle beam (1) front end can connect the beam body of interim beam (8) or other model, and top or toe lasting are strengthened safeguarding.The back rest (4) rear end can connect back group beam, to strengthen the maintenance to back group.The effect that cement backboard or metal backing more help bringing into play this support alternately is set between back timber end face and the top board.Two pairs of holder combination, butt joint, the beam body of indirect suitable length can be used for the coal-face head, tail is made face end support.
