DETAILED DESCRIPTION

[0026] In order to make the personnel in the technical field better understand the present application scheme, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0027] Please refer to Figures 1 to 7 According to an embodiment of the present invention, the present invention provides a coal mine separation detection device, comprising: an anchor pipe 1, a tray 2, a plurality of limiters 3 and a stopper 4, the anchor pipe 1 extending in the depth direction of the anchor hole, the anchor pipe 1 being used to be fixed in the anchor hole; a guide channel 10 for guiding the detection rope 7 to pass through is provided in the anchor pipe 1; an activity space 20 is provided in the tray 2, the activity space 20 extending in the extension direction of the anchor pipe 1, and the activity space 20 passes through both ends of the tray 2; the anchor pipe 1 is passed through the activity space 20; so that the relative position between the tray 2 and the anchor pipe 1 can be adjusted; a plurality of limiters 3 are arranged at intervals on the anchor pipe 1 along the extension direction of the anchor pipe 1 , and multiple limit members 3 are arranged on the outer wall of the anchor tube 1; the stop member 4 is arranged on the inner wall of the activity space 20, and the stop member 4 is arranged to protrude from the inner wall of the activity space 20; a first avoidance channel 11 is formed between the stop member 4 and the inner wall of the activity space 20, and at least one limit member 3 among the multiple limit members 3 is movably inserted in the activity space 20 through the first avoidance channel 11 to adjust the relative position between the tray 2 and the anchor tube 1; and by rotating the anchor tube 1 and / or rotating the tray 2, the limit member 3 inserted in the activity space 20 and located above the stop member 4 is arranged relative to the stop member 4, so that the stop member 4 stops the limit member 3.

[0028] It can be seen that the coal mine separation detection equipment provided by the present invention is provided with an anchor pipe 1, a tray 2, multiple limit members 3 and a stop member 4, and a movable space 20 is provided in the tray 2, the anchor pipe 1 is passed through the movable space 20, the movable space 20 extends along the extension direction of the anchor pipe 1, the movable space 20 runs through both ends of the tray 2, and the anchor pipe 1 is movably arranged relative to the tray 2; at the same time, multiple limit members 3 are arranged on the outer wall of the anchor pipe 1 at intervals along the extension direction of the anchor pipe 1, and multiple limit members 3 are all protruded from the outer wall of the anchor pipe 1; the stop member 4 is arranged on the inner wall of the movable space 20, and the stop member 4 protrudes from the inner wall of the movable space 20; the first avoidance channel 11 is formed between the stop member 4 and the inner wall of the movable space 20. When it is necessary to adjust the relative position between the tray 2 and the anchor pipe 1, at least one of the multiple limit members 3 is movably inserted into the activity space 20 through the first avoidance channel 11, and then the position of the anchor pipe 1 relative to the tray 2 is adjusted according to the preset initial value. When the initial value displayed by the coal mine separation detection equipment is the preset initial value, the limit member 3 located above the stop member 4 (the limit member 3 closest to the stop member 4) is arranged relative to the stop member 4 by rotating the anchor pipe 1 and / or rotating the tray 2, so that the bottom end of the limit member 3 is abutted against the top end of the stop member 4, and then the stop member stops the limit member 3, so that the anchor pipe 1 and the tray 2 are relatively fixedly connected. Thus, by providing multiple limiters 3 spaced apart along the extension direction of the anchor tube 1, the coal mine separation detection device is provided with multiple adjustment positions. By engaging the stopper 4 with any of the multiple limiters 3, the anchor tube 1 can be adjusted to different positions relative to the tray 2, enabling the coal mine separation detection device to adapt to different monitoring requirements. This ensures accurate initial value setting. This not only increases the flexibility of setting the initial value but also enhances the applicability of the coal mine separation detection device. Furthermore, the coordination of the limiters 3 and the stopper 4 enables finer-grained adjustments, ensuring the accuracy and reliability of the adjustments. Furthermore, by providing multiple limiters 3 and the stopper 4, the coordination of each limiter 3 and the stopper 4 forms a fixed connection, ensuring a secure connection between the tray 2 and the anchor tube 1, thereby preventing accidental movement during the monitoring process. This also allows the operator to quickly adjust to the preset initial value as needed, eliminating the need for repeated trial and error adjustments, thereby improving installation efficiency. Furthermore, it effectively ensures that the detection rope 7 is in a taut state after installation. Furthermore, precise adjustment and fixed connection effectively reduce errors caused by improper operation and ensure accurate installation. Furthermore, by quickly and accurately setting the initial value, the starting point accuracy of the monitoring data is improved, thereby enhancing monitoring accuracy. This coal mine separation detection device is easy to operate and effectively solves the technical problem of existing roof separation meters, where the guide tube and tray are integrated into a single structure, making it impossible to adjust the relative position of the tray and guide tube, and thus preventing the quick and accurate setting of the specified initial value.

[0029] Optionally, when assembling the tray 2 with the anchor tube 1, the tray 2 is first placed on the anchor tube 1 through the movable space 20. The tray 2 is extended along the extension direction of the anchor tube 1, thereby driving the stopper 4 to move to a position close to the limiter 3 near the top end of the anchor tube 1. Then, by rotating the anchor tube 1 and / or the tray 2, the limiter 3 is arranged opposite to the first avoidance channel 11. Then, the tray 2 continues to extend along the extension direction of the anchor tube 1 so that all the limiters 3 are inserted into the movable space 20, and the limiter 3 near the bottom end of the anchor tube 1 among the limiters 3 is located at the stopper 4. Then, by rotating the anchor tube 1 and / or the tray 2, the limiter 3 near the bottom end of the anchor tube 1 among the limiters 3 is arranged opposite to the stopper 4. By continuing to move, the stopper 4 is abutted against the limiter 3, thereby relatively and fixedly connecting the anchor tube 1 and the tray 2.

[0030] When the coal mine separation detection equipment is installed on the roof of the tunnel and the initial value needs to be adjusted, the anchor pipe 1 is rotated so that the limiter 3 is located in the first avoidance channel 11 (that is, the limiter 3 and the stopper 4 are staggered); then the anchor pipe 1 is moved so that the anchor pipe 1 moves downward relative to the tray 2, so that the detection rope 7 can be further pulled closer, so that the detection rope 7 is in a taut state. At the same time, the initial value of the coal mine separation detection equipment can also be adjusted according to demand. When the initial value displayed by the coal mine separation detection equipment reaches the preset initial value, the limiter 3 located above the stopper 4 is arranged relative to the stopper 4 by rotating the anchor pipe 1, and the stopper 4 is abutted against the limiter 3 by continuing to move, so that the anchor pipe 1 and the tray 2 are relatively fixedly connected, so that the adjustment of the initial value is completed.

[0031] Specifically, if Figures 1 to 3 As shown, the limiter 3 has a plurality of limit blocks 31, and the plurality of limit blocks 31 are evenly spaced along the circumferential direction of the anchor tube 1. Every two adjacent limit blocks 31 and the outer wall of the anchor tube 1 form a first avoidance groove 32 for avoiding the stopper 4. With such a structural arrangement, the plurality of limit blocks 31 are evenly spaced along the circumferential direction of the anchor tube 1. Only one of the limit blocks 31 is required to cooperate with the stopper 4. The operator can select the nearest or most convenient limit block 31 for adjustment, thereby improving operational efficiency. Moreover, by rotating the tray 2 or rotating the anchor tube 1, the limit block 31 can be quickly adjusted to the desired position of the stopper 4, reducing adjustment time. In addition, the design of the first avoidance groove 32 ensures that the limit block 31 will not interfere with the stopper 4 during movement, reducing the risk of jamming and improving the reliability and service life of the equipment.

[0032] Specifically, if Figure 7As shown, there are multiple stoppers 4, and the multiple stoppers 4 are evenly spaced along the circumferential direction of the tray 2; the multiple stoppers 4 are arranged in a one-to-one correspondence with the multiple limit blocks 31; each adjacent two stoppers 4 in the multiple stoppers 4 and the inner wall of the activity space 20 form a first avoidance channel 11. With such a structural setting, by setting multiple stoppers 4, and the multiple stoppers 4 are arranged in a one-to-one correspondence with the multiple limit blocks 31, the operator can select the nearest or most convenient limit block 31 and stopper 4 for adjustment, thereby improving the operating efficiency. By rotating the tray 2 or rotating the anchor tube 1, the limit block 31 can be quickly adjusted to the desired stopper 4 position, reducing the adjustment time. In addition, the multiple stoppers 4 and the multiple limit blocks 31 are evenly spaced along the circumferential direction, ensuring the uniformity and stability of the connection, and reducing the stress concentration problem that may be caused by single-point fixation.

[0033] Furthermore, there are multiple first avoidance channels 11 , and the multiple first avoidance channels 11 are arranged in a one-to-one correspondence with the multiple limit blocks 31 .

[0034] Optionally, the plurality of limiting blocks of each two adjacent limiting members 3 among the plurality of limiting members 3 are provided in a one-to-one correspondence. It can be understood that the position of the limiting blocks 31 on each limiting member 3 in the circumferential direction is the same, that is, the arrangement of the limiting blocks 31 on each limiting member 3 in the circumferential direction is consistent.

[0035] Optionally, when it is necessary to insert at least one of the multiple limiting members 3 into the activity space 20, the limiting blocks 4 in each column are arranged relative to each first avoidance channel 11 by rotating the tray 2 or rotating the anchoring tube 1, and then at least one of the multiple limiting members 3 is inserted into the activity space 20 by moving the tray 2 or the anchoring tube 1.

[0036] Optionally, when it is necessary to place multiple limit blocks 31 located on multiple stop members 4 within the activity space 20 on corresponding stop members 4, the tray 2 or the anchor tube 1 is rotated so that each limit member 3 is arranged opposite to each stop member 4, and thus each limit member 3 is arranged opposite to the corresponding stop member 4 by moving the tray 2 and / or the anchor tube 1.

[0037] Optionally, the stopper 4 is a stop block.

[0038] Furthermore, if Figure 7As shown, each stopper 4 has an open slot 41 on one end proximal to the anchor tube 1. The slot 41 extends along a pre-set arcuate path, and the slots 41 of each stopper 4 define a guide opening for guiding the anchor tube 1. This structural arrangement allows the anchor tube 1 to pass smoothly during adjustment without interfering with the stopper 4, reducing friction and the risk of jamming. Furthermore, the provision of the guide opening ensures a smooth path for the anchor tube 1 during movement, preventing equipment damage or monitoring errors caused by a poorly defined path.

[0039] Furthermore, if Figure 7 As shown, stopper 4 is located at the bottom of tray 2, and the edge of stopper 4 is aligned with the edge of the bottom of tray 2. With this structural arrangement, stopper 4 is located at the bottom of tray 2, providing additional support and enhancing the structural stability of tray 2. The alignment of the edge of stopper 4 with the edge of the bottom of tray 2 ensures a tight fit between stopper 4 and tray 2, reducing equipment instability caused by structural looseness. The alignment of stopper 4 allows the operator to visually see the position of limit block 31, facilitating confirmation of proper adjustment.

[0040] Optionally, the stopper 4 is integrally formed with the tray 2 .

[0041] Furthermore, the cross-sectional area of ​​the movable space 20 is larger than that of the anchor tube 1. This provides ample space for the anchor tube 1 and / or the stopper 3 to move freely within the tray 2, alleviating operational difficulties caused by limited space. This ample space allows the operator to more easily rotate the tray 2 or the anchor tube 1, quickly adjusting the stopper 31 to the desired stopper 4 position, improving operational efficiency.

[0042] Optionally, the cross-sectional area of ​​the movable space 20 is greater than or equal to the cross-sectional area of ​​the anchoring tube 1 plus the cross-sectional area of ​​the plurality of stoppers 4 plus the cross-sectional area of ​​the limiting member 3 .

[0043] Furthermore, multiple stoppers 3 are arranged at predetermined intervals along the extension direction of the anchor pipe 1; each stopper 3 is fixedly connected to the anchor pipe 1. With this structural arrangement, multiple stoppers 3 are arranged at predetermined intervals along the extension direction of the anchor pipe 1, providing finer-grained adjustment for the coal mine separation detection equipment, ensuring accuracy and reliability of adjustment.

[0044] The size of the preset distance is designed by R&D personnel according to working conditions. For example, every two adjacent limit members 3 among the plurality of limit members 3 are arranged at a preset distance of 1 mm.

[0045] Specifically, if Figures 1 to 3As shown, the coal mine separation detection device also includes a blocking member 5, which is sleeved on the anchor pipe 1 and located below the stopper 3 near the bottom end of the anchor pipe 1 among the multiple stoppers 3. The blocking member 5 is fixedly connected to the anchor pipe 1. The blocking member 5 protrudes from the outer wall of the anchor pipe 1 and is used to block the tray 2. This structural arrangement effectively prevents excessive movement of the tray 2 during downward movement, thereby improving stability.

[0046] Furthermore, if Figures 1 to 3 and Figure 7 As shown, the tray 2 comprises a tray body 21 and an adjustment sleeve 22, which are interconnected. The tray body 21 is positioned above the adjustment sleeve 22 and is adapted to conform to the inner wall of the roadway. A first through-hole is defined within the tray body. The adjustment sleeve extends along the extension direction of the anchor tube 1. A second through-hole is defined within the adjustment sleeve 22, both of which extend along the extension direction of the anchor tube 1. The first through-hole and the second through-hole form a movable space 20. A stopper 4 is provided on the adjustment sleeve 22. This structural arrangement enhances the structural stability of the tray 2, facilitates installation and removal, and improves operational convenience and monitoring accuracy. Furthermore, the connection between the adjustment sleeve 22 and the tray body 21 enhances overall rigidity and stability, reducing deformation or damage caused by external forces during use.

[0047] Optionally, the tray body 21 and the adjustment sleeve 22 are welded together or integrally formed.

[0048] In this embodiment, Figures 1 to 3 As shown, the coal mine separation detection equipment also includes: an anchor claw 6 and a separation detection device 8. The anchor claw 6 is arranged above the anchor pipe 1 and is used to be fixed to a preset anchor point in the anchor hole. One end of the detection rope 7 passes through a guide channel 10 and is connected to the anchor claw 6. The separation detection device 8 is located below the end of the coal mine separation detection equipment away from the anchor claw 6. The coal mine separation detection equipment is installed on the separation detection device 8, and the guide channel 10 is connected to the installation cavity of the separation detection device 8. The end of the detection rope 7 away from the anchor claw 6 passes through the guide channel 10 and the installation cavity of the separation detection device 8 in sequence and is arranged outside the separation detection device 8. With this structural arrangement, by providing the anchor claw 6 and fixing the anchor claw 6 at the preset anchor point, subsequent separation monitoring is facilitated. At the same time, one end of the detection rope 7 is connected to the anchor claw 6, and the other end passes through the guide channel 10 and the installation space of the separation detection device 8, ensuring the accurate path of the detection rope 7 and reducing monitoring errors caused by poor path flow. In addition, by providing the separation detection device 8, the displacement of the detection rope 7 can be monitored in real time, the separation condition of the top plate can be accurately recorded, and the accuracy of the monitoring data can be improved.

[0049] Optionally, the anchor claws 6 are at least two, and the at least two anchor claws 6 are arranged along the depth of the anchor hole to fix the two anchor claws 6 to different preset anchor points. The detection ropes 7 are at least two, and the plurality of detection ropes 7 and the plurality of anchor claws 6 are arranged one by one.

[0050] Specifically, as shown in Figures 1 to 2 , the coal mine separation layer detection device further comprises a rope storage member 300, the rope storage member 300 is arranged outside the separation layer detection device 8, and the rope storage member 300 is used to store the detection rope 7 arranged outside the separation layer detection device 8. Wherein, the rope storage member 300 is used to store the detection rope 7 arranged outside the separation layer detection device 8 means that the detection rope 7 is reserved.

[0051] Optionally, the rope storage member 300 is a wire reel.

[0052] In this embodiment, as shown in Figures 1 to 3 , Figure 5 and Figure 6 , the separation layer detection device 8 comprises a casing 81 and a mechanical monitoring assembly 82, the casing 81 is provided with an installation cavity of the separation layer detection device 8 inside; the mechanical monitoring assembly 82 is installed on the casing 81, and at least part of the mechanical monitoring assembly 82 is located in the installation space of the separation layer detection device 8; the mechanical monitoring assembly 82 is used to monitor the displacement of the detection rope 7; wherein, the mechanical monitoring assembly 82 has a tape measure 821, when the mechanical monitoring assembly 82 detects that the detection rope 7 moves, the starting end of the tape measure 821 extends towards the outside of the casing 81.

[0053] Specifically, as shown in Figures 3 to 6 , the coal mine separation layer detection device further comprises a moving member 9 and a fastener 100, the moving member 9 is movably arranged in the guide channel 10 along the extension direction of the guide channel 10, and at least part of the mechanical monitoring assembly 82 is connected with the moving member 9; one end of the detection rope 7 away from the anchor claw 6 is sequentially arranged outside the separation layer detection device 8 through the guide channel 10, the moving member 9 and the installation cavity of the separation layer detection device 8; the moving member 9 is provided with a communication hole 91 on one side; the fastener 100 is arranged in the moving member 9 through the communication hole 91; the moving member 9 is fixedly connected with the detection rope 7 through the fastener 100, so that the moving member 9 moves along the extension direction of the guide channel 10 when the detection rope 7 moves. By adopting such structure, by arranging the moving member 9, at least part of the mechanical monitoring assembly 82 can be moved through the moving member 9 when the detection rope 7 moves, so that the starting end of the tape measure 821 extends towards the outside of the casing 81 to facilitate the operator to check the displacement.

Then, insert the anchor pipe 1 into the anchor hole and place the tray 2 against the inner wall of the tunnel, making sure it fits in place. Then, tighten the two detection ropes 7 and secure them to their corresponding sliders using two fasteners 100.

[0065] Step 2: The anchor tube 1 is rotated so that the limiting member 3 is located within the first avoidance channel 11 (i.e., the limiting member 3 and the stop member 4 are arranged in an interlaced manner); the anchor tube 1 is then moved downward relative to the tray 2, thereby causing the movable member 9 to move upward relative to the anchor tube 1, thereby causing the winding member 822 to twist and deform, further tightening the detection rope 7 so that the detection rope 7 is in a taut state. As a result, the starting end of the measuring tape 821 extends toward the outside of the housing 81.

[0066] Step 3: When the staff observes through the tape measure 821 or the display part of the digital display component that the initial value of the coal mine separation detection equipment reaches the preset initial value, the anchor pipe 1 is rotated so that the limit member 3 located above the stop member 4 is set relative to the stop member 4, and by continuing to move, the stop member 4 is abutted against the limit member 3, so that the anchor pipe 1 and the tray 2 are relatively fixedly connected, so that the adjustment of the initial value is completed.
