Preferably, the base is fixedly connected with a motor, an output shaft of the motor is connected with a lead screw, and the lead screw is sleeved with the sliding block.
Preferably, both ends all are provided with the stopper on the slide rail.
Preferably, the left end of the top beam is hinged with an inclined block, the lower end of the top beam is hinged with a telescopic oil cylinder, and the extending end of the telescopic oil cylinder is hinged to the bottom of the inclined block.
Has the advantages that: compared with the prior art, the beneficial effects of the utility model are that: the supporting position of the hydraulic supporting column is adjusted through the motor, the screw rod and the sliding block, so that the supporting device is suitable for supporting different angular positions in a mine, and the supporting safety and stability are ensured; the support area is increased by pushing the inclined block through the telescopic oil cylinder, so that the support is more stable and safe.
Drawings
Fig. 1 is the utility model provides a colliery hydraulic support adjusting device's overall structure schematic diagram that stretches out and draws back.
In the drawings: the hydraulic support device comprises a base 1, a top beam 2, a hydraulic jack 3, a hydraulic support column 4, a sliding seat 5, a sliding block 6, a screw rod 7, a motor 8, a sliding rail 9, a limiting block 10, an inclined block 11 and a telescopic oil cylinder 12.
Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.
Examples
Referring to fig. 1, in the embodiment of the utility model, a colliery hydraulic support adjusting device that stretches out and draws back, including base 1, back timber 2, hydraulic jack 3 and hydraulic support post 4, right-hand member fixedly connected with hydraulic jack 3 on the base 1, base 1 left side fixed mounting has slide rail 9, and it is provided with slider 6 to slide on slide rail 9, and fixedly connected with slide 5 on slider 6 has hydraulic support post 4 on the slide 5 to articulate, and hydraulic jack 3 and hydraulic support post 4's upper end all articulates with back timber 2.
Further, a motor 8 is fixedly connected to the base 1, an output shaft of the motor 8 is connected with a lead screw 7, and the slide block 6 is sleeved on the lead screw 7.
Furthermore, two ends of the slide rail 9 are provided with limit blocks 10.
Furthermore, the left end of the top beam 2 is hinged with an inclined block 11, the lower end of the top beam 2 is hinged with a telescopic oil cylinder 12, and the extending end of the telescopic oil cylinder 12 is hinged at the bottom of the inclined block 11.
The use process comprises the following steps:
when the device is used, the whole device is placed in a mine, the hydraulic support column 4 extends out to enable the top beam 2 to support the mine, but the hydraulic support column 4 only extends out and retracts to be free of an intermediate position, so that the top beam 2 is not necessarily attached to the wall of the mine at the angle, and the supporting effect and the safety are affected. Utilize slide 5, slider 6, lead screw 7 and motor 8, can make the angle change of hydraulic support post 4, and then can change the angle of back timber 2 in order to more laminating the mine wall of a well, guaranteed the effect of support. In addition, the support area of the hydraulic support can be increased by jacking the inclined block 11 through the telescopic oil cylinder 12, so that the support is more stable and safe.
In the process, the supporting position of the hydraulic supporting column is adjusted through the motor, the screw rod and the sliding block, so that the support at different angle positions in the mine is adapted, and the safety and the stability of the support are ensured; the support area is increased by pushing the inclined block through the telescopic oil cylinder, so that the support is more stable and safe; the application has the advantages of simple structure, strong practicability and simple operation and is worth popularizing.
