Abstract
The utility model discloses a sliding and toppling prevention device for high type top cutting props used on high-grade general mining working faces whose coal bed inclination angles are higher than 15 DEG and whose mining heights are 1.7-3.2 meters. With a long base arranged on the bottom of a top cutting prop, the top cutting prop and an anchor single hydraulic prop are connected by a sliding prevent jack, and the tank body of the top cutting prop and the tank body of the sliding prevent jack are connected by a canting pull connecting rod, achieving the action of sliding and toppling prevention when props are moved.
Description
The utility model provides a kind of coal supply inclination layer greater than 15 °, and the coal seam mining height is at a kind of device of 1.7～3.2 meters high type supporting roof, particularly a kind of a kind of device that can prevent that the inclined seam breaking-off timber from toppling over and gliding.
High-grade common coal mining face generally adopts hydraulic prop and breaking-off timber to come supporting roof under the coal mine at present, when seam inclination is bigger, after the post alive of breaking-off timber descends, not only topple over easily, also to glide simultaneously, because there is not anti-skidding anti-down measure, thereby causes and move the post difficulty, increase working strength of workers.
The purpose of this utility model is to provide a kind of seam inclination greater than 15 °, and the coal seam mining height is the anti-skidding tilting prevention device of 1.7～3.2 meters breaking-off timber.
The utility model is achieved in that in the bottom of breaking-off timber a long base that lays along the pushing and sliding jack is set, should link to each other with the anchoring hydraulic prop by long base with anti-skidding jack in addition; The tank body of this anti-skidding jack and breaking-off timber is connected with the connecting rod that tiltedly draws of an adjustable-length simultaneously.
Adopt the utility model can guarantee that the high type breaking-off timber of inclined seam does not glide in moving the post process and do not topple over, thereby it is convenient to move post, alleviates workman's manual labor.
Accompanying drawing is the schematic perspective view according to the anti-skidding tilting prevention device of high type breaking-off timber that the utility model proposes.
Describe details and operational circumstances in detail below in conjunction with accompanying drawing according to the concrete device that the utility model proposes:
Breaking-off timber comprises globular hinge joint cap 1, column jack 2, and back-moving spring steel 3, the cross section of 4 ° of long bases of long base is a spill, and pushing and sliding jack 5 is put within it, and the post alive and the breaking-off timber of pushing and sliding jack connect together.The length seat of the tank body of anti-skidding jack 6 and breaking-off timber connects together, and its post of living links to each other with anchoring hydraulic prop 7.The angle β of anti-skidding jack and pushing and sliding jack can regulate, and when seam inclination was big, the β angle should increase.Tiltedly draw connecting rod 8 one to terminate on the tank body of breaking-off timber, the other end is connected on the tank body of anti-skidding jack 6.It should stretching with anti-skidding jack.
The tram that the effect of back-moving spring steel 3 can keep breaking-off timber on the one hand, moreover also play by the spring steel of old man's side and to prevent
Stone is to the impact of tank body.
When breaking-off timber moves forward, post alive should fall earlier, and pushing and sliding jack and anti-skidding jack are shunk simultaneously, breaking-off timber is moved on to the operating position, beginning setting prop, roof supporting.Fall the post alive of anchoring hydraulic prop afterwards, start anti-skidding jack, make its post elongation of living, the anchoring hydraulic prop is moved on to reposition, and setting prop, the diagonal brace top board.Finish to this and once to move the post operation.
In moving the post process, because the angle β between anti-skidding jack and pushing and sliding jack is adjustable, its value increases with the increase of seam inclination, thereby the component that makes progress that increases that anti-skidding jack produces and reaches anti-skidding purpose with the sliding force of balance breaking-off timber.
This device tiltedly draw connecting rod, the pulling force that is transmitted produces a component that makes progress, in order to toppling over of balance breaking-off timber.
The power source of this device is the pressure emulsified liquid pumping plant that is placed in the crossheading.
Claims (3)
1, a kind of seam inclination that is used for is greater than 15 °, mining height is at the anti-skidding tilting prevention device of the breaking-off timber of 1.7～3.2 meters high-grade common coal mining face, it is characterized in that the anti-skidding jack (6) that is provided with long base (4) and forms an angle with long base (4) in the bottom of breaking-off timber, the other end of this anti-skidding jack (6) links to each other with anchoring hydraulic prop (7).The section of long base (4) is a spill, and pushing and sliding jack (5) is put within it, and the post alive of pushing and sliding jack links to each other with breaking-off timber.Between breaking-off timber and anti-skidding jack (6), be provided with and tiltedly draw connecting rod (8).
2, anti-skidding tilting prevention device according to claim 1 is characterized in that the angle β of anti-skidding jack (6) and pushing and sliding jack (5) is adjustable.
