Description

Technical Field

[0001] This utility model relates to the technical field of coal mine delamination monitoring, and specifically to a coal mine delamination detection device. Background Technology

[0002] In existing technologies, roof delamination is the biggest safety hazard in coal mine roadways using bolt support. Roof delamination displacement data needs to be monitored continuously to understand the rationality of the bolt support parameters, the stability of the roof during roadway use, and the development of fractures in the overlying strata. The main purpose is to promptly grasp the roof delamination situation, detect signs of roof instability early, and prevent roof collapse accidents, which is of great significance to coal mine safety production.

[0003] Currently, after installing a roof separation meter, operators typically set an initial value according to regulations to ensure the anchor claws are properly installed, the steel cable is taut, and the starting point for monitoring data is accurate, thus enabling accurate recording of roof separation conditions. However, in existing roof separation meters, the guide tube and tray are an integrated structure, making it impossible to adjust the relative position between the tray and the guide tube, thus hindering the quick and accurate setting of the prescribed initial value. This forces operators to repeatedly attempt and adjust during installation, resulting in low installation efficiency and potentially leading to insufficient steel cable tautness or incomplete anchor claw installation, thereby affecting monitoring accuracy.

The adjusting member is sleeved on the guide tube body and is fixedly connected to the guide tube body. The outer wall of the adjusting member has a moving channel.

[0009] Furthermore, the pallet assembly includes a pallet body and a connecting sleeve connected to each other. The pallet body is located above the connecting sleeve. The pallet body has a first through hole, and the connecting sleeve has a second through hole communicating with the first through hole. Both the first through hole and the second through hole extend along the extension direction of the guide tube body, forming an installation cavity. The inner wall of the connecting sleeve is provided with a limiting member, which is positioned towards the guide tube assembly.

[0010] Furthermore, the adjusting component includes: an adjusting body and a limiting part, both of which are sleeved on the guide tube body, and a moving channel is provided on the adjusting body; the limiting part is connected to the adjusting body and is located below the adjusting body; the limiting part protrudes from the adjusting body and is used to limit the position of the tray assembly.

[0011] Furthermore, there are multiple moving channels, which are spaced apart along the circumferential direction of the adjusting member; there are multiple limiting members, which are spaced apart along the circumferential direction of the connecting sleeve, and each limiting member corresponds to one of the multiple moving channels.

[0012] Furthermore, the coal mine delamination detection equipment also includes: an anchor claw, which is positioned above the guide tube assembly and is used to fix the anchor claw at a preset anchoring point within the anchor hole; one end of the detection rope passes through the guide channel and connects to the anchor claw; a delamination detection device, which is located below the end of the guide tube assembly furthest from the anchor claw, the guide tube assembly is mounted on the delamination detection device, and the guide channel communicates with the installation space of the delamination detection device; the end of the detection rope furthest from the anchor claw passes sequentially through the guide channel and the installation space of the delamination detection device and is positioned on the outside of the delamination detection device.

[0015] Beneficial effects:

[0016] Applying the technical solution of this utility model, the coal mine delamination detection equipment provided by this utility model includes a guide tube assembly and a tray assembly. The tray assembly has an installation cavity, and the guide tube assembly passes through the installation cavity. Simultaneously, a limiting member is provided on the inner wall of the installation cavity and on one of the guide tube assemblies. A moving channel for the limiting member to move is provided on the inner wall of the installation cavity and on the other of the guide tube assemblies. The moving channel extends towards the bottom end of the guide tube assembly along a preset trajectory. Multiple limiting engagement parts that cooperate with the limiting member are provided on the moving channel, and these multiple limiting engagement parts are spaced apart along the extension direction of the guide tube assembly. When it is necessary to adjust the relative position between the tray assembly and the guide tube assembly, the limiting member is moved along the extension direction of the moving channel by rotating the tray assembly and / or rotating the guide tube assembly, causing the guide tube assembly to move downward relative to the tray assembly. When the initial value of the coal mine delamination detection equipment reaches the preset initial value, the limiting member engages with one of the multiple limiting engagement parts, thereby fixing the guide tube assembly and the tray assembly relatively together. Therefore, by means of a limiting member on one of the inner walls of the mounting cavity and the guide tube assembly, and a moving channel for the movement of the limiting member on the other inner wall of the mounting cavity and the guide tube assembly, and by the limiting member engaging with one of the multiple limiting mating parts on the moving channel, the relative position between the tray assembly and the guide tube assembly can be precisely adjusted, thus ensuring the accurate setting of the initial value. Operators can quickly adjust to the preset initial value as needed, without repeated attempts and adjustments, improving installation efficiency. It also effectively ensures that the detection rope remains taut after installation. Furthermore, the moving channel extends along a preset trajectory towards the bottom of the guide tube assembly, ensuring that the limiting member maintains a precise path during movement. And, when the limiting member engages with the limiting mating part, the guide tube assembly and the tray assembly are relatively fixedly connected, thus ensuring that no accidental movement occurs during monitoring. Meanwhile, by moving the limiting component along the extension direction of the moving channel, the tray assembly can be driven to reciprocate along the extension direction of the guide tube assembly, or the guide tube assembly can reciprocate relative to the tray assembly along the extension direction of the guide tube assembly. This allows for flexible adjustment of the relative position between the tray assembly and the guide tube assembly, enabling the coal mine delamination detection equipment to adapt to different monitoring needs. Furthermore, multiple limiting mating parts are spaced apart along the extension direction of the guide tube assembly, providing multiple limiting points and increasing adjustment flexibility. In addition, precise adjustment and fixed connection effectively reduce errors caused by improper operation, ensuring installation accuracy. Moreover, by quickly and accurately setting the initial value, the starting point of the monitoring data is ensured to be accurate, thereby improving monitoring accuracy. This coal mine delamination detection equipment is easy and simple to operate, effectively solving the technical problem in existing roof delamination instruments where the guide tube and tray are an integral structure, making it impossible to adjust the relative position between the tray and the guide tube, thus hindering the quick and accurate setting of the specified initial value.

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

[0027] See also Figures 1 to 7 According to an embodiment of the present invention, a coal mine delamination detection device is provided, comprising: a guide tube assembly 1 and a tray assembly 2. The guide tube assembly 1 extends vertically and has a guide channel 110 for guiding a detection rope 6 through it. The tray assembly 2 has an installation cavity 21 extending along the extension direction of the guide tube assembly 1. The guide tube assembly 1 passes through the installation cavity 21. A limiting member 3 is provided on the inner wall of the installation cavity 21 and on one of the guide tube assemblies 1, and a moving channel 12 for moving the limiting member 3 is provided on the inner wall of the installation cavity 21 and on the other of the guide tube assemblies 1. The moving channel 12 extends along a preset trajectory toward the bottom end of the guide tube assembly 1. The moving channel 12 has a plurality of limiting mating parts 120 that cooperate with the limiting member 3. The plurality of limiting mating parts 120 are spaced apart along the extension direction of the guide tube assembly 1 so as to adjust the relative position between the tray assembly 2 and the guide tube assembly 1 by limiting the limiting member 3 with one of the limiting mating parts 120.

[0028] As can be seen, the coal mine delamination detection equipment provided by this utility model comprises a guide tube assembly 1 and a tray assembly 2, with the tray assembly 2 having an installation cavity 21. The guide tube assembly 1 passes through the installation cavity 21. Simultaneously, a limiting member 3 is provided on the inner wall of the installation cavity 21 and on one of the guide tube assemblies 1, while a moving channel 12 for the limiting member 3 is provided on the inner wall of the installation cavity 21 and on the other of the guide tube assemblies 1. The moving channel 12 extends along a preset trajectory toward the bottom end of the guide tube assembly 1. The moving channel 12 is provided with multiple limiting mating parts 120 that cooperate with the limiting member 3. Multiple limiting engagement parts 120 are spaced apart along the extension direction of the guide tube assembly 1. When it is necessary to adjust the relative position between the tray assembly 2 and the guide tube assembly 1, the limiting member 3 is moved along the extension direction of the moving channel 12 by rotating the tray assembly 2 and / or rotating the guide tube assembly 1, so that the guide tube assembly 1 moves downward relative to the tray assembly 2. When the initial value of the coal mine delamination detection equipment reaches the preset initial value, the limiting member 3 engages with one of the multiple limiting engagement parts 120, thereby fixing the guide tube assembly 1 and the tray assembly 2 relatively. It can be seen that by providing a limiting member 3 on the inner wall of the mounting cavity 21 and one of the guide tube assemblies 1, and by providing a moving channel 12 for the movement of the limiting member 3 on the inner wall of the mounting cavity 21 and the other of the guide tube assemblies 1, and by providing a limiting engagement part 120 on the moving channel 12, the relative position between the tray assembly 2 and the guide tube assembly 1 can be precisely adjusted, thereby ensuring the accurate setting of the initial value. Operators can quickly adjust to the preset initial value as needed, eliminating the need for repeated attempts and adjustments, thus improving installation efficiency. It also effectively ensures that the detection rope 6 is taut after installation. Furthermore, the moving channel 12 extends along a preset trajectory towards the bottom of the guide tube assembly 1, ensuring that the limiting member 3 maintains a precise path during movement. When the limiting member 3 engages with the limiting fitting part 120, it securely connects the guide tube assembly 1 and the tray assembly 2, preventing accidental movement during monitoring. Simultaneously, by moving the limiting member 3 along the extension direction of the moving channel 12, the tray assembly 2 can reciprocate along the extension direction of the guide tube assembly 1, or the guide tube assembly 1 can reciprocate relative to the tray assembly 2 along its extension direction, allowing for flexible adjustment of the relative position between the tray assembly 2 and the guide tube assembly 1, enabling the coal mine delamination detection equipment to adapt to different monitoring needs. Moreover, multiple limiting fitting parts 120 are spaced apart along the extension direction of the guide tube assembly 1, providing multiple limiting points and increasing adjustment flexibility. Furthermore, precise adjustments and secure connections effectively reduce errors caused by improper operation, ensuring installation accuracy. Additionally, quick and accurate initial value setting ensures accurate starting points for monitoring data, thereby improving monitoring accuracy.This coal mine delamination detection equipment is easy and simple to operate, and can effectively solve the technical problem in the existing roof delamination instrument where the guide tube and tray are an integral structure, making it impossible to adjust the relative position between the tray and the guide tube, thus making it impossible to quickly and accurately set the specified initial value.

[0029] Furthermore, the guide tube assembly 1 is movably disposed relative to the tray assembly 2.

[0030] Furthermore, the limiting member 3 is disposed on the inner wall of the mounting cavity 21, and the end of the limiting member 3 away from the inner wall of the mounting cavity 21 is disposed towards the guide tube assembly 1; the moving channel 12 is disposed on the guide tube assembly 1.

[0031] Optionally, the limiting mating part 120 is a limiting groove. The limiting component 3 is a limiting pin. When the initial value of the coal mine delamination detection equipment reaches the preset initial value, the limiting pin is engaged in the limiting groove, thereby fixing the tray assembly 2 and the guide tube assembly 1 relatively.

[0032] Furthermore, at one end of the moving channel 12 away from the bottom end of the guide tube assembly 1, there is a through-hole 122 communicating with the moving channel 12. By rotating the tray assembly 2 and / or rotating the guide tube assembly 1, the limiting member 3 is aligned with the through-hole 122, so that the limiting member 3 enters the moving channel 12 through the through-hole 122.

[0033] Optionally, when assembling the tray assembly 2 and the guide tube assembly 1, the tray assembly 2 is first fitted onto the guide tube assembly 1 through the mounting cavity 21. The tray assembly 2 moves along the extension direction of the guide tube assembly 1, thereby moving the limiting member 3 to a position close to the opening 122. By rotating the tray assembly 2 and / or rotating the guide tube assembly 1, the limiting member 3 is aligned with the opening 122. Then, by moving, the limiting member 3 enters the moving channel 12 through the opening 122. By rotating the tray assembly 2 and / or rotating the guide tube assembly 1, the limiting member 3 moves along the extension direction of the moving channel 12, so that the limiting member 3 engages with the limiting engagement part 120 near the bottom end of the guide tube assembly 1 among the multiple limiting engagement parts 120, thereby fixing the tray assembly 2 and the guide tube assembly 1 relatively.

[0034] When the coal mine delamination detection equipment is installed on the roof of the roadway and the initial value needs to be adjusted, the guide tube assembly 1 is rotated to move the limiting member 3 along the extension direction of the moving channel 12 toward the opening 122. This causes the guide tube assembly 1 to move downward relative to the tray assembly 2, thereby further tightening the detection rope 6 and putting the detection rope 6 in a taut state. At the same time, the initial value of the coal mine delamination detection equipment can be adjusted as needed. When the initial value of the coal mine delamination detection equipment reaches the preset initial value, the limiting member 3 engages with the limiting mating part 120, thereby fixing the guide tube assembly 1 and the tray assembly 2 relatively and fixedly connecting them, thus completing the adjustment of the initial value.

[0035] Furthermore, multiple limiting mating parts 120 are spaced apart along the extension direction of the guide tube assembly 1 according to a preset distance.

[0036] Specifically, if Figure 1 , Figure 2 and Figure 6 As shown, the moving channel 12 has multiple interconnected bent channels 121, which are sequentially arranged along the extension direction of the guide tube assembly 1; each bent channel 121 is provided with a limiting engagement part 120. With this structural arrangement, the limiting member 3 moves along the extension direction of the moving channel 12, and guided by the bent channels 121, the limiting member 3 can accurately reach each limiting engagement part 120. Furthermore, the multiple bent channels 121 and the corresponding limiting engagement parts 120 provide multiple limiting points, allowing the limiting member 3 to be precisely adjusted to multiple preset positions. The limiting engagement part 120 on each bent channel 121 can provide finer-grained adjustments, ensuring accurate setting of the initial value. Simultaneously, the operator can select different limiting engagement parts 120 according to actual needs to flexibly adjust the relative position between the tray assembly 2 and the guide tube assembly 1. The multiple limiting engagement parts 120 ensure accurate setting of the initial value, thereby improving the accuracy of the starting point of the monitoring data.

[0037] Optionally, multiple bend channels 121 are arranged in a stepped manner, sequentially arranged along the extension direction of the guide tube assembly 1, and each pair of adjacent bend channels 121 are connected end to end to form a continuous movement path.

[0038] Specifically, if Figure 6As shown, the bent channel 121 includes: a first connecting channel 1211 and a second connecting channel 1212 connected together. The first connecting channel 1211 extends along a first preset direction, and the extension direction of the first connecting channel 1211 forms a first preset angle α with the extension direction of the guide tube assembly 1, where 0° < α < 90°. The second connecting channel 1212 extends along a second preset direction, and the extension direction of the second connecting channel 1212 is perpendicular to the extension direction of the guide tube assembly 1. The first connecting channel 1211 and the second connecting channel 1212 form the bent channel 121. A limiting fitting part 120 is provided on the second connecting channel 1212. With this structural arrangement, the combination design of the first connecting channel 1211 and the second connecting channel 1212 allows the limiting member 3 to move in multiple directions, ensuring precise adjustment of the limiting member 3. Furthermore, the design of the first connecting channel 1211 effectively prevents the limiting member 3 from sliding during movement, ensuring the stability and reliability of the equipment. Meanwhile, placing the limiting mating part 120 in the second connecting channel 1212 ensures precise alignment between the limiting mating part 120 and the limiting member 3, thereby achieving stable limiting. This design reduces the problem of inaccurate limiting due to tilt or angular deviation. Furthermore, the limiting member 3 has a larger contact area with the limiting mating part 120 in the vertical direction, resulting in stronger friction and effectively preventing the limiting member 3 from sliding under force. It also ensures a secure connection between the guide tube assembly 1 and the tray assembly 2 when the guide tube assembly 1 moves downward. In addition, by providing the first connecting channel, the limiting member 3 can be guided from the opening 122 into the moving channel 12 and move in a predetermined direction. The combined design of the first connecting channel 1211 and the second connecting channel 1212 allows the limiting member 3 to smoothly pass through changes in multiple directions during movement, reducing the risk of jamming. Furthermore, the smooth transition design between the first connecting channel 1211 and the second connecting channel 1212 allows the limiting member 3 to move smoothly at turns, avoiding jamming.

[0039] The extension direction of the second connecting channel 1212 can be understood as a horizontal extension.

[0040] Furthermore, the second connecting channel 1212 is located below the first connecting channel 1211.

[0041] Specifically, if Figures 1 to 7As shown, the guide tube assembly 1 includes a guide tube body 11 and an adjusting member 13. The guide tube body 11 has a guide channel 110 inside, and the guide tube body 11 is used to fix itself in the anchor hole. The adjusting member 13 is sleeved on the guide tube body 11 and is fixedly connected to the guide tube body 11. The outer wall of the adjusting member 13 has a moving channel 12. With this structural arrangement, the guide tube body 11 is fixed in the anchor hole, ensuring the stability and reliability of the equipment. The moving channel 12 on the outer wall of the adjusting member 13 is used to guide the movement of the limiting member 3.

[0042] Furthermore, the adjusting member 13 has a port 122 on one end near the guide tube body 11 that communicates with the moving channel 12.

[0043] Furthermore, the top end of the guide tube body 11 is provided with a plurality of barbs 14, which are spaced apart along the circumferential direction of the guide tube body 11, and the guide tube body 11 is fixed in the anchor hole by means of the barbs 14.

[0044] Optionally, the guide tube body 11 and the adjusting component 13 are welded together or integrally formed.

[0045] Specifically, if Figure 7 As shown, the tray assembly 2 includes a tray body 22 and a connecting sleeve 23 connected together. The tray body 22 is located above the connecting sleeve 23. The tray body 22 has a first through hole, and the connecting sleeve 23 has a second through hole communicating with the first through hole. Both the first and second through holes extend along the extension direction of the guide tube body 11, forming an installation cavity 21. A limiting member 3 is provided on the inner wall of the connecting sleeve 23, facing the guide tube assembly 1. This structural design enhances the structural stability of the tray assembly 2, facilitates installation and disassembly, ensures precise positioning of the limiting member 3, and improves operational convenience and monitoring accuracy. Furthermore, the connection between the connecting sleeve 23 and the tray body 22 enhances the overall rigidity and stability, reducing deformation or damage caused by external forces during use. The limiting member 3 on the inner wall of the connecting sleeve 23 faces the guide tube assembly 1. This design ensures the precise position of the limiting member 3 in the moving channel 12, thereby achieving precise positioning between the tray assembly 2 and the guide tube assembly 1.

[0046] Furthermore, the tray body 22 is used to fit against the inner wall of the tunnel.

[0047] Optionally, the pallet body 22 and the connecting sleeve 23 are welded together or integrally formed.

[0048] Specifically, if Figures 1 to 2 and Figure 6As shown, the adjusting member 13 includes an adjusting body 131 and a limiting part 132. Both the adjusting body 131 and the limiting part 132 are sleeved on the guide tube body 11, and the moving channel 12 is disposed on the adjusting body 131. The limiting part 132 is connected to the adjusting body 131 and is located below the adjusting body 131. The limiting part 132 protrudes from the adjusting body 131 and is used to limit the pallet assembly 2. With this structural arrangement, the limiting part 132 can effectively prevent the pallet assembly 2 from moving excessively during downward movement, thus improving stability.

[0049] Specifically, if Figures 1 to 7 As shown, there are multiple moving channels 12, spaced apart along the circumferential direction of the adjusting member 13; there are also multiple limiting members 3, spaced apart along the circumferential direction of the connecting sleeve 23, with each limiting member 3 corresponding to one of the multiple moving channels 12. This structure, by setting multiple moving channels and multiple limiting members 3, with each limiting member 3 engaging with the limiting mating part 120 in the corresponding moving channel 12, forms a multi-point fixation. This multi-point fixation design significantly enhances the connection strength between the tray assembly 2 and the guide tube assembly 1. The uniform spacing of the limiting members 3 and moving channels 12 along the circumferential direction ensures the uniformity and stability of the connection, reducing stress concentration problems that may arise from single-point fixation. At the same time, the design of multiple limiting members 3 and moving channels 12 provides redundancy; even if one limiting member 3 or moving channel 12 fails, the other limiting members 3 and moving channels 12 can still operate normally, ensuring the reliability of the equipment. Furthermore, the design of multiple limiting components 3 and the moving channel 12 can effectively prevent the limiting components 3 from sliding during movement, ensuring the stability and reliability of the equipment.

[0050] Furthermore, there are multiple ports 122, and each port 122 is configured to correspond one-to-one with a multiple mobile channel 12.

[0051] In this embodiment, as Figures 1 to 2As shown, the coal mine delamination detection equipment also includes: an anchor claw 4 and a delamination detection device 5. The anchor claw 4 is positioned above the guide tube assembly 1 and is used to fix itself to a preset anchor point within the anchor hole. One end of the detection rope 6 passes through the guide channel 110 and connects to the anchor claw 4. The delamination detection device 5 is located below the end of the guide tube assembly 1 furthest from the anchor claw 4. The guide tube assembly 1 is mounted on the delamination detection device 5, and the guide channel 110 communicates with the installation space of the delamination detection device 5. The end of the detection rope 6 furthest from the anchor claw 4 passes through the guide channel 110 and the installation space of the delamination detection device 5, and is positioned on the outside of the delamination detection device 5. This structural arrangement, by setting the anchor claw 4 and fixing it to the preset anchor point, facilitates subsequent delamination monitoring. Simultaneously, the connection of one end of the detection rope 6 to the anchor claw 4 and the passage of the other end through the guide channel 110 and the installation space of the delamination detection device 5 ensures the accuracy of the detection rope 6's path and reduces monitoring errors caused by obstructed paths. In addition, by setting up the delamination detection device 5, the displacement of the detection rope 6 can be monitored in real time, and the delamination of the top plate can be accurately recorded, thus improving the accuracy of the monitoring data.

[0052] Optionally, there are at least two anchor claws 4, which are spaced apart along the depth of the anchor hole to fix the two anchor claws 4 to different preset anchoring points. There are at least two detection ropes 6, and multiple detection ropes 6 and multiple anchor claws 4 are set in a one-to-one correspondence.

[0053] Specifically, the coal mine delamination detection equipment also includes: a rope storage component 7, which is located on the outside of the delamination detection device 5, and is used to store the detection rope 6 located on the outside of the delamination detection device 5.

[0054] The "detection rope 6" used to store the detection rope set on the outside of the delamination detection device 5 refers to the extra detection rope 6 reserved.

[0055] Optionally, the rope storage component 7 is a rope reel.

[0056] Specifically, if Figures 1 to 2 and Figure 5 As shown, the delamination detection device 5 includes: a housing 51 and a mechanical monitoring component 52. The housing 51 has an installation space for the delamination detection device 5. The mechanical monitoring component 52 is mounted on the housing 51, and at least a portion of the mechanical monitoring component 52 is located within the installation space of the delamination detection device 5. The mechanical monitoring component 52 is used to monitor the displacement of the detection rope 6. The mechanical monitoring component 52 has a measuring tape 521, and when the mechanical monitoring component 52 detects movement of the detection rope 6, the starting end of the measuring tape 521 extends outward toward the outside of the housing 51.

[0057] Furthermore, such as Figures 1 to 2 and Figure 5As shown, the delamination detection device 5 also includes a take-up member 522, which is installed in the installation space of the delamination detection device 5; a measuring tape 521 is sleeved on the take-up member 522, and the take-up member 522 drives the measuring tape 521 to move, thereby realizing the movement of the starting end of the measuring tape 521.

[0058] At the same time, one end of the take-up piece 522 is connected to the detection rope 6 so that the movement of the detection rope 6 can drive the take-up piece 522 to twist and deform, thereby causing the starting end of the measuring tape 521 to extend outward toward the outer side of the housing 51.

[0059] Specifically, if Figures 1 to 3 and Figure 5 As shown, the slider 8 is slidably disposed in the guide channel 110 along the extension direction of the guide channel 110. The slider 8 is connected to the take-up member 522 and the detection rope 6 respectively. When the detection rope 6 moves, it drives the slider to slide along the extension direction of the guide channel 110, and the slider 8 drives the take-up member 522 to undergo torsional deformation.

[0060] Optionally, the retractor 522 is a coil spring.

[0061] Optionally, the number of sliders 8 is the same as the number of detection ropes 6.

[0062] Optionally, the detection rope 6 is a steel rope.

[0063] In this embodiment, the delamination detection device 5 further includes a digital display component, which is disposed inside the housing 51 and connected to the mechanical monitoring component 52. The digital display component is used to display the displacement of the detection rope 6 monitored by the mechanical monitoring component 52. The housing 51 is provided with an observation window 53, which is disposed opposite to the display part of the digital display component. The operator can observe the displacement of the detection rope 6 displayed on the display part of the digital display component through the observation window 53.

[0064] Optionally, the process of adjusting the initial values ​​of the coal mine delamination detection equipment is as follows:

[0065] Step 1: After assembling the coal mine delamination detection equipment and fixing the two anchor claws 4 to their corresponding anchoring points, gently pull the corresponding detection rope 6 after each anchor claw 4 is fixed to its anchoring point to confirm that the anchor claw 4 is anchored. Then, insert the guide tube body 11 into the anchor hole, and then place the tray assembly 2 against the inner wall of the roadway, making it fit against the inner wall. Next, tighten the two detection ropes 6 and then secure them to their corresponding sliders using two fasteners 9.

[0066] Step 2: By rotating the guide tube assembly 1, the limiting member 3 moves towards the opening 122 along the extension direction of the moving channel 12. This causes the guide tube assembly 1 to move downward relative to the tray assembly 2, and the slider 8 to move upward relative to the guide tube assembly 1. This causes the winding member 522 to twist and deform, while simultaneously tightening the detection rope 6, putting it in a taut state. As a result, the starting end of the measuring tape 521 extends outward toward the outer side of the housing 51.

[0067] Step 3: When the staff observes through the tape measure 521 or the display of the digital display component that the initial value of the coal mine delamination detection equipment has reached the preset initial value, the limit piece 3 and the limit fitting part 120 are limited and fitted, so that the guide tube assembly 1 and the tray assembly 2 are relatively fixedly connected, so that the initial value is adjusted. At this time, the guide tube assembly 1 is also fixed in the anchor hole by multiple barbs 14.
