[0032] The present utility model will be further introduced below in conjunction with the accompanying drawings and specific embodiments:

[0033] Refer to Figures 1 to 5 , a moving mechanism of a self-moving support device in a coal mine, including: a single track 1, a first driving member 2, a second driving member 3, a first hydraulic telescopic member 5, a connecting cross frame 4, and a clamping assembly 6.

[0034] Among them, the single track 1 is fixedly installed on the roof of the coal mine roadway, and the moving mechanism moves on the single track 1; specifically, the first driving member 2 and the second driving member 3 are both slidably installed on the single track 1, the first driving member 2 and the second driving member 3 are arranged in the same direction, a first hydraulic telescopic member 5 is connected between the first driving member 2 and the second driving member 3, the first hydraulic telescopic member 5 can be a two-way hydraulic cylinder, the connecting cross frame 4 is fixedly installed with the second driving member 3, and the connecting cross frame 4 is used to connect the support structure (not shown in the drawings). A clamping assembly 6 for clamping the single track 1 is fixedly installed on the connecting cross frame 4. That is, after the moving mechanism moves to a suitable position, the clamping assembly 6 clamps and fixes the single track 1 to keep the position of the connecting cross frame 4 stable.

[0035] The structures of the first driving member 2 and the second driving member 3 are the same. The following specifically describes the first driving member 2 in detail: The first driving member 2 includes: a sliding frame 201, a friction assembly 202, a swinging assembly 204, and a limiting shaft 205.

[0036] The top of the sliding frame 201 is slidably connected to the single track 1, the friction assembly 202 is slidably connected to the sliding frame 201, and one side of the friction assembly 202 faces the single track 1. When the friction assembly 202 presses against the side of the single track 1, the first driving member 2 is fixed to the single track 1. The middle of the swinging assembly 204 is rotatably connected to the bottom of the sliding frame 201, the top of the swinging assembly 204 corresponds to the bottom of the friction assembly 202, the bottom end of the swinging assembly 204 is movably connected to the end of the first hydraulic telescopic member 5, and the limiting shaft 205 is fixedly installed at the bottom of the sliding frame 201, and the top of the swinging assembly 204 is located between the limiting shaft 205 and the friction assembly 202.

[0037] From the above description of the structure of the first driving member 2, when the first hydraulic telescopic member 5 pulls the bottom end of the swinging assembly 204 on the right side, the top of the swinging assembly 204 moves away from the friction assembly 202, that is, the swinging assembly 204 abuts against the side of the limiting shaft 205. At this time, the first driving member 2 can slide on the single track 1. When the first hydraulic telescopic member 5 pushes the bottom end of the swinging assembly 204 on the right side, the top of the swinging assembly 204 presses the friction assembly 202, and the friction assembly 202 pushes up against the single track 1. At this time, the first driving member 2 is fixed to the single track 1.

[0038] By analogy, it can be known that the second driving member 3 can be realized. When the first hydraulic telescopic member 5 pulls the second driving member 3 on the left side, the second driving member 3 is fixed to the single track 1. When the first hydraulic telescopic member 5 pushes the second driving member 3 on the left side, the second driving member 3 can slide on the single track 1.

[0039] Thus, it is only necessary to control the repeated extension and contraction of the first hydraulic telescopic member 5 to achieve movement (self-climbing and creeping) on a single track. The operation is relatively convenient. After reaching the appropriate position, the clamping assembly 6 clamps and fixes the single track 1 to maintain the stability of the position of the connecting cross frame 4.

[0040] In one embodiment, the clamping assembly 6 includes: a two-way hydraulic telescopic member 601, the two-way hydraulic telescopic member 601 is fixedly connected to the connecting cross frame 4, a connecting member 602 is fixedly connected to the telescopic end of the two-way hydraulic telescopic member 601, and a clamping member 603 is fixedly connected to the top of the connecting member 602.

[0041] One side of the clamping member 603 facing the single track 1 is a clamping surface 603a. The clamping surfaces of the two clamping members 603 are arranged oppositely. By controlling the two telescopic ends of the two-way hydraulic telescopic member 601 to drive the two connecting members 602 inward, the two connecting members 602 drive the two clamping members 603 to clamp the single track 1 inward.

[0042] In one embodiment, a sliding opening 4a is formed in the connecting cross frame 4. The connecting member 602 is slidably matched with the sliding opening 4a. The sliding opening 4a plays a role in stabilizing and guiding the connecting member 602 to ensure the stability of the clamping process.

[0043] In one embodiment, the sliding frame 201 includes: a sliding part 201a and an installation part 201b which are integrally arranged. The sliding part 201a is located above the installation part 201b. An installation channel 201c is formed between the sliding part 201a and the installation part 201b. The friction assembly 202 is slidably installed inside the installation channel 201c. A limiting frame 203 is fixedly connected to the inner side of the installation part 201b and below the friction assembly 202. The limiting frame 203 limits the lowest position of the friction assembly 202 to prevent the friction assembly 202 from falling off.

[0044] In one embodiment, the friction assembly 202 includes: a friction block 202a. The top surface of the friction block 202a is a friction surface. A bottom plate 202b is fixedly connected to the bottom of the friction block 202a. The bottom plate 202b corresponds to the position of the limiting frame 203.

[0045] In one embodiment, the swinging assembly 204 includes: a connecting part 204b. A connecting shaft 204c is rotatably installed on the connecting part 204b. The connecting shaft 204c is fixedly connected to the installation part 201b. The two ends of the connecting part 204b are respectively fixedly connected with a first connecting end 204a and a second pressing end 204d. The first connecting end 204a is rotatably connected to the end of the first hydraulic telescopic member 5.

[0046] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
