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. The main purpose is to timely grasp the roof delamination situation and detect the signs of roof instability as early as possible to avoid the occurrence of roof collapse accidents, which is of great significance to the safe production of coal mines.

It will also increase the cost and frequency of maintenance. Utility Model Content

[0028] See also Figures 1 to 6According to an embodiment of the utility model, the utility model provides a displacement measuring device, which comprises: a housing 10, a detection rope 11 and a reeling component 12, wherein the housing 10 is provided with a first installation cavity 101 and a wire outlet hole 102 communicating with the first installation cavity 101; at least part of the detection rope 11 is arranged in the first installation cavity 101, and one end of the detection rope 11 passes through the wire outlet hole 102 and is connected with the fluke 2; the reeling component 12 is movably arranged in the first installation cavity 101, and the reeling component 12 has a receiving space 120 and a reading part 1210, wherein the receiving space 120 is used to receive the detection rope 11; and the reading part 1210 is used to display the displacement of the detection rope 11 in the receiving space 120; wherein a first observation area 103 is further provided on the housing 10, and the first observation area 103 corresponds to at least part of the reading part 1210, and the staff reads the data corresponding to the displacement of the detection rope 11 displayed on the reading part 1210 through the first observation area 103.

[0029] It can be seen that the displacement measuring device 1 provided by the utility model is provided with a housing 10, a detection rope 11 and a reeling component 12 by simply setting up the housing 10, and the housing 10 is provided with a first installation cavity 101 and a wire outlet hole 102 connected to the first installation cavity 101, the first installation cavity 101 is located in the housing 10, and the reeling component 12 can be movably arranged in the first installation cavity 101, so that the reeling component 12 can be protected by the housing 10, and the reeling component 12 can be prevented from being damaged by external environmental factors (such as high humidity, heavy dust, etc.), so that the normal operation of the reeling component 12 is ensured by the housing 10 and the service life of the reeling component 12 is improved. At the same time, the reeling component 12 has a storage space 120, and the storage space 120 is used to accommodate the detection rope 11; so that the detection rope 11 can be stored and received by the reeling component 12, thereby reducing the occupied space, and at the same time, the detection rope can be quickly and smoothly unfolded to reach a predetermined length when needed, thereby improving the working efficiency. In addition, the housing 10 is provided with a first observation area 103 and the retracting component 12 also has a reading part 1210. The first observation area 103 corresponds to at least part of the reading part 1210, so that the staff can directly observe the data corresponding to the displacement of the detection rope 11 displayed on the reading part 1210 through the first observation area 103, which improves the convenience and efficiency of operation, while reducing the interference and potential damage risks of the harsh environment in the coal mine to the internal equipment. The reliability and convenience of operation of the displacement measuring device 1 are improved; thereby ensuring that the displacement measuring device 1 can still obtain reliable and accurate displacement measurement data under complex working conditions such as coal mines. The displacement measuring device 1 can effectively solve the technical problem that the displacement measuring device in the prior art is easily interfered by environmental factors and the measurement accuracy is reduced in harsh environments such as high humidity and strong dust that are unique to coal mines.

[0030] Specifically, Figure 2As shown, the housing 10 is provided with a groove 1030 and a first observation window 1031. The groove 1030 is provided with an observation hole 1032 and an indicator 1033 connected to the first installation cavity 101. The observation hole 1032 is arranged corresponding to at least part of the reading part 1210. The indicator 1033 is located on one side of the observation hole 1032. The indicator 1033 is used to assist the staff to read the data corresponding to the displacement of the detection rope 11 displayed on the reading part 1210. The first observation window 1031 is installed on the groove 1030 to wrap the groove 1030, so as to prevent dust or water vapor from entering the first installation cavity 101 from the observation hole 1032. Among them, the groove 1030, the first observation window 1031, the observation hole 1032 and the indicator 1033 form the first observation area 103.

[0031] Further, the indicating portion 1033 is in the shape of an arrow, the indicating portion 1033 is protruding from the groove 1030 , the indicating portion 1033 is located in the observation hole 1032 , and the indicating portion 1033 is at a middle position of the observation hole 1032 .

[0032] In this embodiment, if Figure 3 As shown, the winding component 12 includes: a wire wheel 121, which is rotatably arranged in the first installation cavity 101; a first accommodating groove is provided on the side wall of the wire wheel 121 along the circumferential direction of the wire wheel 121, and the inner wall of the first accommodating groove encloses a accommodating space 120; at least a part of the detection rope 11 is wound around the wire wheel 121; a reading part 1210 is arranged on the end of the wire wheel 121 corresponding to the first observation area 103; wherein, when the detection rope 11 is displaced by an external force, the wire wheel 121 rotates along the first direction with the displacement of the detection rope 11; and the reading part 1210 displays data corresponding to the displacement of the detection rope 11 according to the rotation of the wire wheel 121.

[0033] The first direction mentioned above refers to a specific direction in which the wire wheel 121 rotates when the detection rope 11 is stretched by an external force. Specifically, when the detection rope 11 is pulled outward so that its length increases, the wire wheel 121 rotates in a manner coordinated with the stretching direction of the detection rope 11, which is the first direction mentioned above.

[0034] Furthermore, when the displacement measuring device 1 does not start measuring, the detection rope 11 will extend a portion outside the housing 10, and the length of the detection rope 11 in the housing 10 is set according to the working requirements, and at this time, the zero mark on the reading part 1210 will be located in the area of ​​the observation hole 1032, and at the same time, the indicating part 1033 also points to the zero mark on the reading part 1210 (that is, the external force does not act on the detection rope 11 at this time). When the external force acts on the detection rope, the detection rope 11 on the wire wheel 121 is pulled out of the housing 10 due to the external force (that is, the detection rope 11 is displaced by the external force), and the wire wheel 121 will rotate with the displacement of the detection rope 11. When the wire wheel 121 stops rotating, the reading part 1210 will display data corresponding to the displacement of the detection rope 11 according to the rotation of the wire wheel 121, and the staff reads it through the first observation area 103.

[0035] Specifically, Figure 3 and Figure 4 As shown, a first mounting groove 1211 is further provided on the wire wheel 121; a first protrusion 109 is provided on the inner wall of the first mounting cavity 101 corresponding to the first mounting groove 1211, and at least a part of the first protrusion 109 is located in the first mounting groove 1211; the winding component 12 also includes: an elastic element 122, the elastic element 122 is installed in the first mounting groove 1211, and one end of the elastic element 122 is fixed on the first protrusion 109, and the other end of the elastic element 122 is fixed on the first mounting groove 1211; wherein the elastic element 122 has a torsion state and a recovery state, when the detection rope 11 is displaced by an external force, the elastic element 122 is in a torsion state according to the rotation of the wire wheel 121; when the detection rope 11 is recovered, the elastic element 122 is in a recovery state, and the elastic element 122 drives the wire wheel 121 to rotate in a second direction opposite to the first direction through its own recovery force, so as to recover the detection rope 11.

[0036] The torsion state mentioned above refers to a state in which the elastic element 122 undergoes torsion deformation under the action of torque.

[0037] Specifically, Figure 4 As shown, a second protrusion 110 is further provided on the inner wall of the first installation cavity 101 corresponding to the first installation groove 1211. The second protrusion 110 is a hollow structure, and the first protrusion 109 is located in the second protrusion 110. The second protrusion 110 is adapted to the first installation groove 1211, and the second protrusion 110 is inserted in the first installation groove 1211, and the second protrusion 110 is used to support the wire wheel 121.

[0038] Specifically, a first placement space is formed between the first installation groove 1211 and the second protruding portion 110 , and the elastic element 122 is located in the first placement space.

[0039] Furthermore, the cross-sections of the first mounting groove 1211 , the first protrusion 109 , and the second protrusion 110 are all circular, and the axes of the first mounting groove 1211 , the first protrusion 109 , and the second protrusion 110 all coincide with the axis of the wire wheel 121 .

[0040] Furthermore, when the reel 121 rotates, one end of the elastic element 122 fixed on the inner wall of the first mounting groove 1211 will rotate accordingly, so that the elastic element 122 will undergo torsional deformation as the reel 121 rotates. During this process, the elastic element 122 will store energy. When the detection rope 11 is recovered, the elastic element 122 begins to release the elastic potential energy stored previously. At this time, the elastic element 122 will generate a rewinding torque on the reel 121. This torque drives the reel 121 to rotate in a second direction opposite to the first direction, thereby realizing automatic recovery of the detection rope 11.

[0041] Specifically, Figure 4 As shown, the retracting component 12 further includes: a fixing member 123, the fixing member 123 is arranged on the first mounting groove 1211, and the fixing member 123 is arranged to protrude from the first mounting groove 1211, one end of the elastic element 122 is connected to the fixing member 123, and one end of the elastic element 122 is fixed to the first mounting groove 1211 through the fixing member 123. The fixing member 123 is located in the first placement space.

[0045] Furthermore, the principle of the displacement measuring member 14 measuring the displacement of the detection rope 11 is that when the detection rope 11 is displaced by an external force, the wire wheel 121 rotates accordingly, and drives at least part of the displacement measuring member 14 connected thereto to rotate through the connecting member 13. Thus, the displacement measuring member 14 converts the rotation of the wire wheel 121 into a change in resistance value, and then converts the change in resistance value into an electrical signal (change in voltage or current) through a circuit, thereby realizing accurate measurement of the displacement of the detection rope.

[0046] Preferably, the displacement measuring element 14 is a potentiometer.

[0047] Specifically, Figure 5 As shown, a connecting hole is provided on the first mounting groove 1211, and the displacement measuring device 1 further comprises: a coupling 18, the coupling 18 is sleeved on the connecting member 13, the coupling 18 is located between the connecting member 13 and the connecting hole, and the wire wheel 121 is connected to the connecting member 13 through the coupling 18.

[0050] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the reading portion 1210 is a metric indication mark, and the metric indication mark is arranged along the circumferential direction of the wire wheel 121; the displacement measuring device 1 also includes: a full circle dial 16, the full circle dial 16 is arranged in the first mounting cavity 101, the full circle dial 16 is connected to the wire wheel 121, and the full circle dial 16 is used to display the number of rotations of the wire wheel 121; wherein, a third observation window 106 is also provided on the housing 10, the third observation window 106 is spaced apart from the first observation area 103, and the third observation window 106 is arranged corresponding to at least part of the display portion 160 of the full circle dial 16, and the staff can read the number of rotations of the wire wheel 121 through the third observation window 106.

[0055] Since the metric indication marks on the wire wheel 121 are limited, they may not be sufficient to cover all possible displacements or provide highly accurate readings, especially when a large range or high resolution measurement is required. To this end, a full circle dial 16 is added to one side of the wire wheel 121 to effectively expand the measurement range and accuracy.

[0056] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, a wiring channel 107 is provided in the shell 10, and the wiring channel 107 is respectively connected with the wire outlet hole 102 and the first installation cavity 101; an insertion groove 108 is also provided on the shell 10, and the extension direction of the insertion groove 108 and the extension direction of the wiring channel 107 form a first preset angle, and the first preset angle is greater than 0° and less than or equal to 90°; the displacement measuring device 1 also includes: a locking member 17, at least a part of the locking member 17 is movably inserted in the insertion groove 108, and the locking member 17 is used to lock the length of the detection rope 11 extending out of the shell 10.

[0060] Preferably, the marking member 19 is a lock buckle.

[0061] Furthermore, when the length of the detection rope 11 needs to be adjusted, the locking member 17 is moved in a direction away from the insertion slot 108, and the detection rope 11 is released from the limiting slot 170, so that it can be freely extended or shortened to adjust to the required length. After the length adjustment is completed, the locking member 17 is reinserted into the insertion slot 108, and the detection rope 11 will be re-stuck in the limiting slot 170. This action ensures that the position of the detection rope 11 is fixed, and no unconscious movement occurs, thereby maintaining stability and accuracy during measurement or operation, and avoiding measurement errors or safety hazards caused by unnecessary sliding of the detection rope.

[0062] Specifically, when the displacement measuring device 1 has not been installed, the detection rope 11 exposed to the outside is temporarily stored in a winding box.

[0063] The utility model also provides a coal mine separation detection device, such as Figure 7 and Figure 8As shown, the coal mine separation detection equipment includes: a fixing device 3, a displacement measuring device 1 and an anchor claw 2, the fixing device 3 is used to be fixed on the inner wall of the tunnel, and is provided with a second mounting groove 30 and a connecting channel 31 connected to the second mounting groove 30; the displacement measuring device 1 is the displacement measuring device 1 of the above-mentioned embodiment, the displacement measuring device 1 is installed on the second mounting groove 30, and the end of the detection rope 11 of the displacement measuring device 1 located outside the displacement measuring device 1 passes through the connecting channel 31 and is connected to the anchor claw 2; wherein, there is at least one displacement measuring device 1, and there is at least one anchor claw 2, a plurality of displacement measuring devices 1 are arranged one-to-one with a plurality of anchor claws 2, and a plurality of displacement measuring devices 1 are arranged in the second mounting groove 30 at intervals.

[0064] Specifically, the fixing device 3 includes a tray 32 and an anchoring cylinder 33. The tray 32 is connected to the anchoring cylinder 33, and the tray 32 is located below the anchoring cylinder 33. The tray 32 is provided with a second mounting groove 30, and a connecting passage 31 is provided in the anchoring cylinder 33. A plurality of barbs 300 are arranged at intervals in the circumferential direction on the outer wall of the anchoring cylinder 33. The anchoring cylinder 33 is fixed in the anchor hole through the plurality of barbs 300, and then the tray 32 is fixed to the inner wall of the lane through the anchoring cylinder 33.

[0065] Furthermore, the coal mine separation detection equipment is used to monitor the separation displacement data of the tunnel roof in real time.

[0066] Specifically, Figure 7 As shown, the coal mine separation detection equipment also includes: a signal collection device 4, which is respectively connected to the plurality of displacement measuring devices 1 by signals, and the signal collection device 4 is used to collect the data measured by each displacement measuring device 1, so as to transmit the data measured by each displacement measuring device 1 to the terminal through the signal collection device 4.

[0067] Furthermore, the installation process of the coal mine separation detection equipment is as follows:

[0068] First, each displacement measuring device 1 is connected to the signal collection device 4 for signal connection, and then each displacement measuring device 1 is installed in the second installation groove 30 of the tray 32 at intervals, wherein the length of the detection rope 11 of each displacement measuring device 1 outside the displacement measuring device 1 is different, and the length of the detection rope 11 of each displacement measuring device 1 outside the displacement measuring device 1 is set according to customer requirements.

[0069] Secondly, one end of the detection rope 11 of each displacement measuring device 1 located outside the displacement measuring device 1 is connected to the corresponding anchor claw 2 through the connecting channel 31; then, each anchor claw 2 connected with the detection rope 11 is pushed to each preset anchor point by a push rod, wherein the installation position of each anchor claw 2 in the anchor hole is determined according to the length of the exposed detection rope 11 of the corresponding displacement measuring device.

[0070] Finally, the anchoring tube 33 is fixed in the anchor hole through a plurality of barbs 300 so that the tray 32 is fixed on the inner wall of the tunnel.

[0071] When the installation is completed, the exposed detection rope 11 of each displacement measuring device 1 is in a tensioned state. At the same time, the locking piece of each displacement measuring device 1 is moved away from the insertion slot 108 to release the detection rope 11 (that is, the detection rope 11 is not in the limit slot 170).

[0072] Furthermore, the working principle of the coal mine separation detection equipment is:

[0073] For example, four preset anchoring points A, B, C, and D are arranged in sequence in the anchor hole from high to low, and each preset anchoring point is provided with an anchor claw 2. When the coal seam at C begins to subside (i.e., when separation occurs at C), the anchor claws 2 at C and the anchor claws 2 at D will be driven to move downward, and then the tray 32 will be driven to move downward, and then a relative displacement will occur between the anchor claws 2 at A and the anchor claws 2 at B and the corresponding displacement measuring devices 1. At this time, a part of the detection rope 11 in the displacement measuring device 1 corresponding to the anchor claws 2 at A and the anchor claws 2 at B will be pulled out, and then the wire wheel 121 will be driven to rotate, so that the wire wheel 121 drives the displacement measuring member 14 to rotate, so that it generates an electrical signal, and the corresponding displacement number will be displayed on the reading part 1210 and the digital display component 15. Since the displacement measuring devices 1 corresponding to the anchor claws 2 at A and the anchor claws 2 at B will display the displacement number, and the displacement measuring devices 1 corresponding to the anchor claws at C and the anchor claws at D will not display the displacement number, it can be judged that the coal seam at position C begins to fall off. At the same time, the data of each displacement measuring device 1 will also be transmitted to the signal collection device 4, and uploaded to the terminal by the signal collection device 4 for analysis by the staff.

[0074] In order to reduce space occupation, the signal collection device 4 can be replaced by a centralized display device 5, specifically, as Figure 8 As shown, the coal mine separation detection equipment also includes: a centralized display device 5, which is signal-connected to multiple displacement measuring devices 1 respectively, and the centralized display device 5 is used to alternately display the measurement data corresponding to each displacement measuring device 1, and is used to collect the data measured by each displacement measuring device 1, and transmit the collected data measured by each displacement measuring device 1 to the terminal.

[0075] 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 1, and each displacement measuring device 1 is connected to the centralized display device 5 through the corresponding quick-insert self-locking connector 6.

[0076] The utility model provides a displacement measuring device, which comprises: a shell 10, a detection rope 11 and a reeling component 12, wherein the shell 10 is provided with a first installation cavity 101 and a wire outlet hole 102 communicated with the first installation cavity 101; at least part of the detection rope 11 is arranged in the first installation cavity 101, and one end of the detection rope 11 passes through the wire outlet hole 102 and is connected with the anchor claw 2; the reeling component 12 is movably arranged in the first installation cavity 101, and the reeling component 12 has a accommodating space 120 and a reading part 1210, wherein the accommodating space 120 is used to accommodate the detection rope 11; and the reading part 1210 is used to display the displacement of the detection rope 11 located in the accommodating space 120; wherein a first observation area 103 is further provided on the shell 10, and the first observation area 103 corresponds to at least part of the reading part 1210, and a staff member reads data corresponding to the displacement of the detection rope 11 displayed on the reading part 1210 through the first observation area 103.

[0077] It can be seen that the displacement measuring device 1 provided by the utility model is provided with a housing 10, a detection rope 11 and a reeling component 12 by simply setting up the housing 10, and the housing 10 is provided with a first installation cavity 101 and a wire outlet hole 102 connected to the first installation cavity 101, the first installation cavity 101 is located in the housing 10, and the reeling component 12 can be movably arranged in the first installation cavity 101, so that the reeling component 12 can be protected by the housing 10, and the reeling component 12 can be prevented from being damaged by external environmental factors (such as high humidity, heavy dust, etc.), so that the normal operation of the reeling component 12 is ensured by the housing 10 and the service life of the reeling component 12 is improved. At the same time, the reeling component 12 has a storage space 120, and the storage space 120 is used to accommodate the detection rope 11; so that the detection rope 11 can be stored and received by the reeling component 12, thereby reducing the occupied space, and at the same time, the detection rope can be quickly and smoothly unfolded to reach a predetermined length when needed, thereby improving the working efficiency. In addition, the housing 10 is provided with a first observation area 103 and the retracting component 12 also has a reading part 1210. The first observation area 103 corresponds to at least part of the reading part 1210, so that the staff can directly observe the data corresponding to the displacement of the detection rope 11 displayed on the reading part 1210 through the first observation area 103, which improves the convenience and efficiency of operation, while reducing the interference and potential damage risks of the harsh environment in the coal mine to the internal equipment. The reliability and convenience of operation of the displacement measuring device 1 are improved; thereby ensuring that the displacement measuring device 1 can still obtain reliable and accurate displacement measurement data under complex working conditions such as coal mines. The displacement measuring device 1 can effectively solve the technical problem that the displacement measuring device in the prior art is easily interfered by environmental factors and the measurement accuracy is reduced in harsh environments such as high humidity and strong dust that are unique to coal mines.
