The delamination displacement data of the tunnel roof needs to be monitored at any time to understand the rationality of the anchor support parameter setting, the stability of the tunnel roof during use, and the development of the crack position of the overburden layer on the tunnel roof.

[0026] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0027] See also Figures 1 to 5According to an embodiment of the utility model, the utility model provides an anchor claw, the anchor claw 1 comprising: an anchor claw body 10, a plurality of hook claw parts 11 and a first limiting part 12, a mounting cavity 100 is provided in the anchor claw body 10, a plurality of avoidance holes 101 are arranged at intervals along the circumferential direction of the anchor claw body 10 on the side wall of the anchor claw body 10, and each avoidance hole 101 is communicated with the mounting cavity 100; the plurality of hook claw parts 11 are arranged one by one correspondingly with the plurality of avoidance holes 101; at least a part of each hook claw part 11 is located in the mounting cavity 100, and a supporting end 110 of each hook claw part 11 can be movably penetrated in the corresponding avoidance hole 101 01; each avoidance hole 101 is used to avoid the corresponding hook claw part 11; the first limiting part 12 is movably mounted on the fluke body 10, and the first limiting part 12 moves along the height direction of the fluke body 10; the first limiting part 12 is used to limit each hook claw part 11; wherein the hook claw part 11 has a retracted state and an expanded state, when the inner wall of the first limiting part 12 abuts against the supporting end 110 of each hook claw part 11, the hook claw part 11 is in the retracted state, and when the first limiting part 12 moves toward the supporting end 110 away from each hook claw part 11, the hook claw part 11 is in the expanded state.

[0028] It can be seen that the anchor claw provided by the utility model is provided with an anchor claw body 10, a plurality of hook claw parts 11 and a first limiting part 12 by simply setting a plurality of avoidance holes connected to the installation cavity 100 on the anchor claw body 10, and the support end 110 of each hook claw part 11 can be movably inserted into the corresponding avoidance hole 101, so that the support end of each hook claw part 11 can move toward the installation cavity 100 through the corresponding avoidance hole 101 when avoidance is needed, thereby reducing the direct contact and friction between the support end 110 of each hook claw part 11 and the anchor hole wall, thereby reducing the installation resistance. At the same time, the support end 110 of the hook claw part 11 can be movably inserted into the avoidance hole 101, so that each hook claw part 11 can flexibly adjust its posture according to the working conditions, avoiding damage to the anchor hole wall or increasing the difficulty of installation due to hard squeezing, and improving the adaptability of the anchor claw 1 and the anchor hole.

[0029] In addition, the first limiting portion 12 is movably mounted on the fluke body 10, and when the hook portion 11 is in the retracted state, the inner wall of the first limiting portion 12 abuts against the supporting end 110 of each hook portion 11, and then each hook portion 11 is locked in the retracted state through the first limiting portion 12, thereby reducing unnecessary movement, ensuring that when the fluke 1 is installed in the anchor hole, each hook portion 11 is always in the retracted state, thereby improving the installation efficiency, and in the retracted state, since each hook portion 11 is locked, the space occupied by the fluke 1 is reduced, making it more convenient to carry and store, which is beneficial to transportation and reduces the space requirement during on-site storage, and avoids accidental injury to the staff by the hook portion 11, thereby improving safety. When the hook claw portion 11 is in the open state, the first limiting portion 12 moves toward the support end 110 away from each hook claw portion 11, so that the first limiting portion 12 avoids the support end 110 of each hook claw portion 11. At this time, the support end 110 of each hook claw portion 11 is no longer limited by the first limiting portion 12, and is quickly opened, thereby fixing the anchor claw 1 on the preset anchor point. It can be seen that through the flexible avoidance of the hook claw portion 11 and the control of the first limiting portion 12, the direct friction between the anchor claw 1 and the anchor hole wall is significantly reduced, the risk of damage to the anchor hole wall is reduced, and the wear of the anchor claw 1 itself is also reduced, and the service life of the anchor claw 1 is extended. In addition, the installation efficiency of the anchor claw 1 is improved, making the installation process smoother, reducing the consumption of manpower and time, and also improving the safety during the installation process, and reducing the risk of accidents caused by improper installation. The anchor claw has a simple structure and is easy to operate. It can effectively solve the technical problem that the hook claw of the anchor claw may cause friction with the anchor hole wall during the installation process of the anchor claw in the prior art, thereby increasing the difficulty of installation.

[0030] Specifically, each avoidance hole 101 extends along the height direction of the fluke 1, and its purpose is to provide space for the hook portion 11 to avoid obstacles or reduce friction, ensuring that the hook portion 11 can pass or adjust its position smoothly when moving without being hindered or causing unnecessary damage to surrounding structures.

[0031] Furthermore, the first limiting portion 12 is a limiting ring.

[0032] Furthermore, the detection rope 30 is connected to the first limiting part 12. When the anchor claw 1 is in the initial state, the inner wall of the first limiting part 12 abuts against the supporting end 110 of each hook claw part 11, so that each hook claw part 11 is in a retracted state. When the anchor claw 1 is installed to a preset anchor point specified in the anchor hole, the detection rope 30 is pulled to move the first limiting part 12 toward the supporting end 110 away from each hook claw part 11, so that the first limiting part 12 avoids the supporting end 110 of each hook claw part 11. At this time, the supporting end 110 of each hook claw part 11 is no longer restricted by the first limiting part 12 and is quickly opened, so that the supporting end 110 of each hook claw part 11 is firmly supported on the inner wall of the anchor hole, so that the supporting end 110 of each hook claw part 11 is closely fitted with the anchor hole wall, so that the anchor claw 1 is fixed on the preset anchor point.

[0033] Specifically, Figure 4 As shown, a clamping groove 120 matching the supporting end 110 of the hook claw portion 11 is provided on the inner wall of the first limiting portion 12; there are multiple clamping grooves 120, and the multiple clamping grooves 120 are arranged at intervals along the circumferential direction of the first limiting portion 12, and the multiple clamping grooves 120 are arranged one by one with the multiple hook claw portions 11; wherein, when the hook claw portion 11 is in the retracted state, the supporting end 110 of each hook claw portion 11 is clamped in the corresponding clamping groove 120. With such a structural arrangement, it can be ensured that the hook claw portion 11 is firmly locked in the retracted state and is not easy to fall out, thereby improving the stability and safety of the entire fluke.

[0034] Furthermore, when the hook claw portion 11 is in the retracted state, the supporting end 110 of each hook claw portion 11 is clamped in the corresponding clamping groove 120 , so as to further restrict the corresponding hook claw portion 11 through each clamping groove 120 . When it is necessary to transform each hook claw part 11 from the retracted state to the expanded state, the detection rope 30 is pulled to drive the first limiting part 12 to move toward the supporting end 110 away from each hook claw part 11. At this time, the supporting end 110 of each hook claw part 11 will move toward the direction of the mounting cavity 100 along with the movement of the first limiting part 12, so that the supporting end 110 of each hook claw part 11 is separated from the corresponding clamping groove 120. When the first limiting part 12 completes the avoidance of the supporting end 110 of each hook claw part 11, at this time, the supporting end 110 of each hook claw part 11 is no longer restricted by the first limiting part 12 and is quickly expanded, and then the supporting end 110 of each hook claw part 11 is firmly supported on the inner wall of the anchor hole, so that the supporting end 110 of each hook claw part 11 is tightly fitted with the anchor hole wall, thereby fixing the anchor claw 1 on the preset anchor point.

[0035] Specifically, Figure 5As shown, the fluke 1 also includes: a support frame 13 and a plurality of elastic members 14, the support frame 13 is arranged in the installation cavity 100, and each support portion of the support frame 13 abuts against the inner wall of the installation cavity 100; the plurality of elastic members 14 are all arranged on the support frame 13, and each elastic member 14 has at least one connecting end 140, and the plurality of connecting ends 140 are arranged one-to-one with the plurality of hook claws 11, and one end of each hook claw 11 away from the first limiting portion 12 is connected to the corresponding connecting end 140; each hook claw 11 is arranged at intervals along the circumferential direction of the support frame 13; wherein, when the hook claw 11 is in a retracted state, the elastic member 14 is in a compressed state, and when the hook claw 11 is in an open state, the elastic member 14 is in a restored state. With such a structural arrangement, the support frame 13 is arranged to support the plurality of elastic members 14. At the same time, by providing multiple elastic members 14, each of which has at least one connecting end 140, the multiple connecting ends 140 are arranged one by one with the multiple hook claws 11, and the end of each hook claw 11 away from the limiting portion is connected to the corresponding connecting end 140, and then the elastic force and restoring force of each elastic member 14 are used to drive each hook claw 11, so that the hook claw 11 can automatically return to the preset open state after being released. Thereby reducing the need for manual intervention, improving the working efficiency, and ensuring that the hook claw 11 can stably reach the optimal working state each time it is used. At the same time, the elastic member 14 can provide necessary buffering during the process of unfolding and retracting the hook claw 11, absorb and disperse external forces, and protect the entire fluke 1 from impact damage. This not only enhances the durability of the fluke 1, but also ensures the smoothness and safety of the operation. In addition, by utilizing the compression force of the elastic member 14, it is ensured that when each hook claw 11 is in the retracted state, the support end 110 of the hook claw 11 is closely abutted against the first limiting portion 12 to form a stable locking state. This not only prevents the hook portion 11 from accidentally unfolding in an unexpected situation, but also ensures stability and safety before transportation and installation.

[0036] Furthermore, when the hook portion 11 needs to be released, the staff only needs to control the movement of the first limiting portion 12, and the restoring force of the elastic member 14 will naturally push the hook portion 11 to expand to the expanded state without the need for additional complicated operating steps, thereby simplifying the entire operating process.

[0037] Preferably, the elastic member 14 is a torsion spring having two connecting ends 140 .

[0038] Preferably, the support frame 13 is a cross-shaped support frame, with two torsion springs, and four avoidance holes 101 and four hook parts 11. The two torsion springs are cross-sheathed on the support frame 13, and the connection end 140 of each torsion spring is arranged toward the corresponding avoidance hole 101, and one end of each hook part 11 away from the limiting part is connected to the corresponding connection end 140. With such a structural setting, the cross-shaped support frame provides support points in four directions, which can distribute external forces more evenly and increase the stability and balance of the entire structure.

[0039] Specifically, Figures 1 to 3 As shown, the fluke 1 further includes: a second limiting portion 15, which is mounted on the fluke body 10 and protrudes from the side wall of the fluke body 10; the second limiting portion 15 is located near the bottom end of the fluke body 10, and the second limiting portion 15 is used to limit the first limiting portion 12, so as to prevent the first limiting portion 12 from falling off from the fluke body 10.

[0040] Specifically, there are a plurality of second limiting portions 15 , and the plurality of second limiting portions 15 are arranged at intervals along the circumferential direction of the fluke body 10 .

Such a structural setting ensures that the detection rope 30 is firmly connected to the first limiting part 12, and prevents the detection rope 30 from accidentally falling out or sliding during operation.

[0043] Furthermore, the locking portion 16 is a lock buckle.

The tray 22 is connected to the anchoring tube 23, and the tray 22 is located below the anchoring tube 23. The tray 22 is provided with a mounting groove 20, and the anchoring tube 23 is provided with a connecting passage 21. A plurality of barbs 200 are arranged at intervals in the circumferential direction on the outer wall of the anchoring tube 23, and the anchoring tube 23 is fixed in the anchor hole through the plurality of barbs 200, and then the tray 22 is fixed to the inner wall of the lane through the anchoring tube 23.

[0048] Specifically, the fixing device 2 further includes a plurality of clamping parts 24, each of which is arranged at intervals in the mounting groove 20, and each of which corresponds to each of the displacement measuring devices 3.

[0057] Furthermore, the coal mine separation detection equipment also includes: multiple quick-insert self-locking connectors 6, and the multiple quick-insert self-locking connectors 6 are arranged one-to-one with the multiple displacement measuring devices 3, and each displacement measuring device 3 is connected to the centralized display device 5 through the corresponding quick-insert self-locking connector 6.

[0058] The utility model provides an anchor claw, which includes: an anchor claw body 10, a plurality of hook claw parts 11 and a first limiting part 12. The anchor claw body 10 is provided with a mounting cavity 100, and the side wall of the anchor claw body 10 is provided with a plurality of avoidance holes 101 arranged at intervals along the circumferential direction of the anchor claw body 10, and each avoidance hole 101 is communicated with the mounting cavity 100; the plurality of hook claw parts 11 are arranged in a one-to-one correspondence with the plurality of avoidance holes 101; at least a part of each hook claw part 11 is located in the mounting cavity 100, and the support end 110 of each hook claw part 11 can be movably penetrated in the corresponding avoidance hole 101; each The avoidance hole 101 is used to avoid the corresponding hook portion 11; the first limiting portion 12 is movably mounted on the fluke body 10, and the first limiting portion 12 moves along the height direction of the fluke body 10; the first limiting portion 12 is used to limit each hook portion 11; wherein the hook portion 11 has a retracted state and an expanded state, when the inner wall of the first limiting portion 12 abuts against the support end 110 of each hook portion 11, the hook portion 11 is in the retracted state, and when the first limiting portion 12 moves toward the support end 110 away from each hook portion 11, the hook portion 11 is in the expanded state.

[0059] It can be seen that the anchor claw provided by the utility model is provided with an anchor claw body 10, a plurality of hook claw parts 11 and a first limiting part 12 by simply setting a plurality of avoidance holes connected to the installation cavity 100 on the anchor claw body 10, and the support end 110 of each hook claw part 11 can be movably inserted into the corresponding avoidance hole 101, so that the support end of each hook claw part 11 can move toward the installation cavity 100 through the corresponding avoidance hole 101 when avoidance is needed, thereby reducing the direct contact and friction between the support end 110 of each hook claw part 11 and the anchor hole wall, thereby reducing the installation resistance. At the same time, the support end 110 of the hook claw part 11 can be movably inserted into the avoidance hole 101, so that each hook claw part 11 can flexibly adjust its posture according to the working conditions, avoiding damage to the anchor hole wall or increasing the difficulty of installation due to hard squeezing, and improving the adaptability of the anchor claw 1 and the anchor hole.

[0060] In addition, the first limiting portion 12 is movably mounted on the fluke body 10, and when the hook portion 11 is in the retracted state, the inner wall of the first limiting portion 12 abuts against the supporting end 110 of each hook portion 11, and then each hook portion 11 is locked in the retracted state through the first limiting portion 12, thereby reducing unnecessary movement, ensuring that when the fluke 1 is installed in the anchor hole, each hook portion 11 is always in the retracted state, thereby improving the installation efficiency, and in the retracted state, since each hook portion 11 is locked, the space occupied by the fluke 1 is reduced, making it more convenient to carry and store, which is beneficial to transportation and reduces the space requirement during on-site storage, and avoids accidental injury to the staff by the hook portion 11, thereby improving safety. When the hook claw portion 11 is in the open state, the first limiting portion 12 moves toward the support end 110 away from each hook claw portion 11, so that the first limiting portion 12 avoids the support end 110 of each hook claw portion 11. At this time, the support end 110 of each hook claw portion 11 is no longer limited by the first limiting portion 12, and is quickly opened, thereby fixing the anchor claw 1 on the preset anchor point. It can be seen that through the flexible avoidance of the hook claw portion 11 and the control of the first limiting portion 12, the direct friction between the anchor claw 1 and the anchor hole wall is significantly reduced, the risk of damage to the anchor hole wall is reduced, and the wear of the anchor claw 1 itself is also reduced, and the service life of the anchor claw 1 is extended. In addition, the installation efficiency of the anchor claw 1 is improved, making the installation process smoother, reducing the consumption of manpower and time, and also improving the safety during the installation process, and reducing the risk of accidents caused by improper installation. The anchor claw has a simple structure and is easy to operate. It can effectively solve the technical problem that the hook claw of the anchor claw may cause friction with the anchor hole wall during the installation process of the anchor claw in the prior art, thereby increasing the difficulty of installation.
