[0001] The utility model relates to the technical field of coal mine anchor withdrawal, and more particularly to an anchor withdrawal lock device for a coal mine mining tunnel. Background Art

[0002] The coal mine anchor withdrawer is a device used in coal mine support systems. It is mainly used for withdrawing anchors. Anchors play a very important role in the support process of coal mines. However, in some cases, such as when maintenance or replacement of support structures is required, the anchors must be withdrawn. The working principle of the anchor withdrawer is usually to apply a certain force to the anchor to release it from the rock or coal seam, thereby achieving the purpose of safe withdrawal.

[0003] At present, during the use of the anchor withdrawal lock device for coal mine recovery tunnels in the existing technology, some existing equipment needs to remove the clamp after the anchor withdrawal is completed before the equipment can be removed, which makes the equipment more time-consuming and labor-intensive to use; and the clamping length supported by some equipment is fixed. When the exposed anchor cable is too long, the equipment may lack a support point, and the excess anchor cable needs to be cut before the anchor can be withdrawn, which may result in poor flexibility when the equipment is used. Therefore, there is an urgent need for an anchor withdrawal lock device for coal mine recovery tunnels to solve the above problems. Utility Model Content

The setting of the handle 12 makes it easier for the staff to lift the equipment, so that the equipment can be more conveniently moved in a narrow mine, so that it can be used to a certain extent. The portability of the equipment is greatly improved when it is used. The electric hydraulic push rod 13 can be powered by an external power supply, and then the hydraulic pump inside the electric hydraulic push rod 13 is driven to generate hydraulic pressure, thereby pushing the output end of the electric hydraulic push rod 13 to move up and down, thereby pushing the anchor column 14 to move synchronously. The two groups of moving blocks 16 can move inside the moving groove 15, and the two groups of moving blocks 16 will not shake or rotate inside the moving groove 15, and will not leave the inside of the moving groove 15. Moreover, the two groups of moving blocks 16 can drive the two groups of clamping plates 17 and the threaded plates 18 to move synchronously when moving, and the bidirectional screw A rotating handle is provided at one end of 110, so that the staff can rotate the bidirectional screw 110 more easily. The bidirectional screw 110 can rotate inside the two sets of connecting seats 19 without being separated from the two sets of connecting seats 19, or moving inside the two sets of connecting seats 19. The bidirectional screw 110 can drive the two sets of threaded plates 18 and the clamping plates 17 to move closer to or away from each other when rotating. When the outer surfaces of the opposite sides of the two sets of clamping plates 17 are in contact with the outer surface of the anchor cable, the anchor can be withdrawn. After the anchor is withdrawn, the bidirectional screw 110 can be rotated to make the two sets of clamping plates 17 move away from each other, and the equipment can be removed at this time.

[0024] Example 2

[0025] like Figures 4 and 5As shown, this embodiment also proposes: a support structure 2, the support structure 2 includes a first support seat 21 and a snap seat 25, and the snap seat 25 is provided with two groups, and the first support seat 21 is fixedly connected to the upper surface of the anchor column 14, and a snap plate 22 is fixedly connected to the outer surface of the upper end of the first support seat 21, and the snap plate 22 is provided with two groups, and the surfaces of the two groups of snap plates 22 are respectively fixedly connected to the limiting blocks 23, the upper surface of the first support seat 21 is attached to the second support seat 24, the two groups of snap seats 25 are respectively fixedly connected to the outer surface of the lower end of the second support seat 24, and the sizes of the two groups of snap seats 25 are respectively adapted to the sizes of the two groups of snap plates 22, and the upper surface of the second support seat 24 is fixedly connected to the support plate 26, The first support seat 21 can move synchronously with the movement of the anchor withdrawal column 14. When the upper surface of the second support seat 24 is in contact with the upper surface of the first support seat 21, the second support seat 24 is rotated, which can drive the two sets of engaging seats 25 to move synchronously, thereby engaging with the outer surfaces of the two sets of engaging plates 22, thereby fixing the first support seat 21 and the second support seat 24. The setting of the two sets of limit blocks 23 can limit the movement range of the two sets of engaging seats 25, preventing the two sets of engaging seats 25 from excessive movement and separation from the outer surfaces of the two sets of engaging plates 22. When the second support seat 24 is fixed to the first support seat 21, the overall height of the support structure 2 can be increased, so that the support plate 26 can be pressed against the wall to support the anchor withdrawal process.

[0026] Working principle: when the equipment is in use, first determine whether to install the second support seat 24 according to the length of the anchor cable disassembled according to the need. When the second support seat 24 needs to be installed, the lower surface of the second support seat 24 is attached to the upper surface of the first support seat 21. Then, the second support seat 24 is rotated to drive the two sets of engaging seats 25 to rotate synchronously, so that the two sets of engaging seats 25 are engaged with the outer surfaces of the two sets of engaging plates 22, thereby fixing the second support seat 24 and the first support seat 21. Then, the support plate 26 is pressed against the wall. At this time, the anchor cable is inserted into the inner side of the supporting structure 2 and the two sets of clamping plates 17 on the opposite side. Then, the bidirectional screw 110 is rotated to drive the two sets of clamping plates 17 to move closer to each other. At this time, the two sets of clamping plates 17 clamp the outer surface of the anchor cable. Then, the electric hydraulic push rod 13 is powered by an external power supply. The output end of the electric hydraulic push rod 13 pushes the anchor column 14 to move upward, and pulls the anchor cable outward with the support plate 26 as the support point.

[0027] After the anchor is withdrawn, the bidirectional screw 110 is rotated to drive the two sets of clamping plates 17 away from each other, so that the outer surfaces of the opposite sides of the two sets of clamping plates 17 are separated from the outer surface of the anchor cable. At this time, the equipment can be removed. The above is the entire working principle of this utility model.
