Description
Technical field
The present invention relates to a kind of coal mine hydraulic supporting, relate in particular to a kind of traction sliding hydraulic support system.
Background technology
The support apparatus in colliery is the critical facility that ensures coal miner safety, existing suspended or gliding hydraulic bracket all is to be the support apparatus that vacant state moves forward by after-poppet is mentioned in the pillar unloading, support bore will be delivered to adjacent stent by the bindiny mechanism between support perpendicular to the gravity of back timber and the pulling force that is parallel to back timber, this strength that just makes that connection will be born between this is bigger, especially the combination gliding hydraulic bracket that all links together for all supports by bindiny mechanism, the internal stress that produces between support all can be superimposed upon in the bindiny mechanism, causes bindiny mechanism often to be damaged.
Summary of the invention
The invention reside in provides a kind of rational mounting system simple in structure, stressed, combined by adjacent stent, support is equiped with mobile support pole mechanism, plays a supporting role when support moves, make the stress of support more reasonable, can effectively avoid the damage of bindiny mechanism between support.
Specifically, the present invention is achieved through the following technical solutions: a kind of traction sliding hydraulic support system is characterized in that: described mounting system is combined by the traction sliding hydraulic support connection.Traction sliding hydraulic support comprises crossbeam, back timber, passing jack, hydraulic prop, guiding device and support system.Guiding device one end is fixed in crossbeam, and the other end is slidingly connected in the back timber; Pass jack one end and be connected in crossbeam, the other end is connected in back timber.Pass jack can make when flexible back timber in the guiding device restricted portion near or away from crossbeam.Support system vertically is installed on the back timber bottom surface.
Hydraulic prop vertically is installed on the back timber bottom surface, and it is more than two that quantity is installed, and mainly plays the effect of supporting traction formula gliding hydraulic bracket, and when needs moved frame, hydraulic prop can shrink.
Support system vertically is installed on the back timber bottom surface, comprises positioning sleeve, support column and telescoping cylinder.Positioning sleeve is fixedly set in the back timber bottom surface, and support column slides and is arranged at positioning sleeve inside, and telescoping cylinder one end is connected in back timber, and the other end is connected in support column.Telescoping cylinder can make when flexible support column in the positioning sleeve restricted portion near or away from back timber, the quantity that is provided with of support column is at least one.
Traction sliding hydraulic support system is connected to form by plural at least traction sliding hydraulic support, can install linkage between the crossbeam of adjacent traction sliding hydraulic support, makes connected crossbeam form incorporate reinforcing beam.When support moved, its crossbeam will link into an integrated entity with an adjacent crossbeam at least.Be provided with slide block between the back timber of adjacent stent, when back timber slides, play supplemental support and position-limiting action.
The guiding device of traction sliding hydraulic support can be chosen as girder construction, plank frame or rod shaped structure.
The present invention's advantage compared to existing technology is: support guarantees safer, stable in moving process, deflection has not improved the security reliability of coal miner's working environment, adopts mobile support pole mechanism, support force distributed uniform in the support moving process, compact conformation, reasonable.

The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, traction sliding hydraulic support system is combined by three traction sliding hydraulic supports connections.Traction sliding hydraulic support comprises crossbeam 1, passes jack 2, guiding device 3, hydraulic prop 4, back timber 5 and support system.Guiding device 5 one ends are fixed in crossbeam 1, and the other end is slidingly connected in the back timber 5.Pass jack 2 one ends and be connected in crossbeam 1, the other end is connected in back timber 5, pass jack 2 can make when flexible back timber 5 in guiding device 5 restricted portions near or away from crossbeam 1.
Support system comprises positioning sleeve 7, support column 9 and telescoping cylinder 8, positioning sleeve 7 is fixedly set in the bottom surface of back timber 5, support column 9 slides and is arranged at positioning sleeve 7 inside, telescoping cylinder 8 one ends are connected in back timber 5, the other end is connected in support column 9, telescoping cylinder 8 can make when flexible support column 9 in positioning sleeve 7 restricted portions near or away from back timber 5.
Between the crossbeam 1 of adjacent traction sliding hydraulic support linkage 10 is housed, makes each crossbeam 1 form incorporate reinforcing beam.Simultaneously, between the back timber 5 of adjacent traction sliding hydraulic support, be provided with slide block 6, when back timber 5 slides, play supplemental support and position-limiting action.
In conjunction with Fig. 4, Fig. 5 and shown in Figure 6, when mounting system needs integral body to move frame, can carry out following operation to the traction sliding hydraulic support that is positioned at the centre position earlier:
1) stretches out telescoping cylinder 8, make support column 9, be higher than about hydraulic prop 4 bottom 100mm to support column 9 bottoms away from back timber 5.
2) shrink hydraulic prop 4, away from ground, while support column 9 kiss the earths.
3) shrink passing jack 2, back timber 5 is slided to crossbeam 1 direction, 9 pairs of back timbers 5 of support column are played a supporting role in this process, and 6 pairs of back timbers 5 of slide block play supplemental support and spacing effect.
4) back timber 4 puts down hydraulic prop 4 after sliding into assigned address.
So far the frame that moves of finishing the centre position traction sliding hydraulic support moves, and adopting uses the same method again moves the traction sliding hydraulic support that is adjacent respectively, and the integral body of finally finishing mounting system moves.
