Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model proposes an anti-tipping coal mine support, including a support 1, through which a rod 2 passes and is slidably connected to the support 1, with a support plate 3 fixedly connected to the end of the rod 2, a second hydraulic cylinder 4 fixedly connected to the outer wall of the support 1, the output end of the second hydraulic cylinder 4 fixedly connected to the outer wall of the support plate 3, a first hydraulic cylinder 13 fixedly connected to the outer wall of the support 1, a support block 14 fixedly connected to the output end of the first hydraulic cylinder 13, a sliding plate 11 slidably connected to the support 1, a hinge rod 12 hinged to the sliding plate 11, and a moving mechanism provided on the support 1.

[0030] In this embodiment of the utility model, to improve the convenience of the device, the moving mechanism specifically includes a fixed plate 51, a U-shaped rod 52 hinged to the fixed plate 51, the U-shaped rod 52 passing through a roller 53 and rotatably connected to the roller 53, a fixed rod 54 fixedly connected to the outer wall of the U-shaped rod 52, a through groove 551 provided on the fixed block 55, the through groove 551 slidably connected to the fixed rod 54, a short rod 552 fixedly connected to the outer wall of the fixed block 55, a sliding rod 553 fixedly connected to the short rod 552, and the sliding rod 553 is connected to the fixed plate 51. The extrusion block 56 has a sloping groove 561, which is slidably connected to the sliding rod 553. A long rod 562 is fixedly connected to the outer wall of the extrusion block 56. A moving rod 57 passes through the bracket 1 and the fixing plate 51 and is slidably connected to the bracket 1 and the fixing plate 51. The moving rod 57 passes through the long rod 562 and is fixedly connected to the long rod 562. A pedal 573 is fixedly connected to the end of the moving rod 57. The moving rod 57 passes through the moving block 571 and is fixedly connected to the moving block 571. The moving block 571 has a slot 572.

[0031] Furthermore, a limit rod 10 is fixedly connected to the outer wall of the bracket 1, and an elastic block 15 is slidably connected to the inner wall of the bracket 1. A pull rod 16 is fixedly connected to the outer wall of the elastic block 15. The pull rod 16 passes through the bracket 1 and is slidably connected to the bracket 1. The pull rod 16 passes through the rotating rod 17 and is rotated to connect with the rotating rod 17.

[0032] In this utility model, when the device needs to be moved, the hydraulic cylinder 13 is activated first. Driven by the hydraulic cylinder 13, the support block 14 moves downwards, and the bracket 1 is lifted by the hydraulic cylinder 13. Then, the foot pedal 573 is pressed, causing the moving rod 57 to move downwards. Through the transmission of the long rod 562, the pressing block 56 moves downwards synchronously. When the pressing block 56 moves downwards, the inclined groove 561 applies force to the sliding rod 553, causing the short rod 552 to slide on the outer wall of the fixed plate 51. At this time, the fixed block 55 applies force to the fixed rod 54, causing the U-shaped rod 52 to drive the roller 53 to rotate 90 degrees, making the roller 53 vertical to the ground. Simultaneously, during this process, the moving block 571 presses against the elastic locking block 15, causing the elastic locking block 15 to fully enter the inner wall of the bracket 1. When the elastic locking block 1... When the 5th roller 53 overlaps with the slot 572, the elastic block 15 will spring into the slot 572 under the force of the spring, thus limiting the roller 53. Then, the bracket 1 is moved to the appropriate position, the sliding plate 11 is pulled out, and the hinge rod 12 is unfolded. Through the design of the sliding plate 11 and the hinge rod 12, the force-bearing area of ​​the bracket 1 can be increased, thereby improving the stability of the bracket 1. Then, the hydraulic cylinder 13 is activated again, so that the support block 14 supports the bracket 1 again. Then, the pull rod 16 is pulled, so that the elastic block 15 is disengaged from the slot 572, thereby releasing the limitation of the roller 53. Then, the rotating rod 17 is rotated to lock onto the limiting rod 10. Then, the pedal 573 is lifted to reset the roller 53. Then, the hydraulic cylinder 13 is activated again to place the bracket 1 on the ground. Finally, the hydraulic cylinder 4 is activated to push the support plate 3 against the top of the mine.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
