Description

Technical Field

[0001] This invention relates to the field of tunnel monitoring and protection technology, specifically a deformation monitoring device for mines with faults. Background Technology

[0002] Fault zones in mines are typical tectonic zones in the geological environment, mostly formed by the fracturing and displacement of rock strata caused by crustal movement. During the excavation of mine tunnels, when a fault is exposed or adjacent to a tunnel, the original strata continuity is disrupted. The rock mass within the fault fracture zone, due to long-term tectonic stress, weathering, and groundwater action, often exhibits phenomena such as fissure opening and fault plane displacement, significantly disturbing the stability of the surrounding rock of the tunnel.

[0003] Tunnel fault deformation is characterized by its hidden and sudden nature, making it difficult to detect deep displacement and stress changes in a timely manner through manual inspections alone. Conducting deformation monitoring can prevent accidents such as collapses and spalling from injuring personnel, prevent obstruction of ventilation and transportation systems, and reduce the cost of large-scale repairs later through early intervention. It is a key technical means to ensure safe and efficient mine production.

[0004] Existing deformation monitoring devices mostly only monitor the fault area. However, when deformation occurs at the fault area in the roadway, they are mostly only monitored without timely protection. Moreover, the monitoring results cannot be observed intuitively. If the deformation is not dealt with in time, it may lead to greater deformation, resulting in greater economic losses and casualties. Summary of the Invention

[0005] In view of this, a deformation monitoring device for mines with faults is proposed to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a deformation monitoring device for mines with faults, comprising a support, wherein the support is fixedly installed at the fault location in the roadway, and its top is in contact with the top of the roadway, and further comprising:

[0007] A monitoring component, mounted on the support, is used to monitor deformation at the fault location;

[0008] An indicator component is disposed at the end of the support away from the top of the roadway and is associated with the monitoring component for indicating roadway deformation information based on monitoring results;

[0009] The monitoring component includes a mounting box disposed on the bracket. The mounting box has a sliding groove, in which a mounting plate is slidably mounted. Multiple support members are fixedly mounted on the mounting plate. The mounting box has a mounting cavity, in which a connecting rod is disposed. One end of the connecting rod is fixedly connected to the mounting plate. The monitoring component and the indicator component work together to enhance the monitoring and stabilization effect during deformation.

[0010] Preferably, the support includes a base plate and a top plate, with a connecting rod fixedly installed between the base plate and the top plate. A spring is sleeved on the connecting rod, with one end of the spring fixedly connected to the base plate and the other end of the spring fixedly connected to the top plate. A support rod is fixedly installed on the top plate, with a support block fixedly installed at the end of the support rod away from the top plate. The support block is in contact with the top of the tunnel.

[0011] Preferably, the bracket has an installation assembly in its groove, the installation assembly having multiple installation grooves, and grooves symmetrically formed on both sides of the installation grooves. A first guide roller and a second guide roller are rotatably installed in the grooves, and the first guide roller and the second guide roller are interleaved.

[0012] Preferably, the indicating component includes a cavity in which multiple movable blocks are slidably mounted. A pressing block is abutted above each movable block, and a push rod is fixedly mounted on the pressing block. The end of the push rod away from the pressing block is fixedly connected to the mounting box.

[0013] Preferably, guide rods are symmetrically installed on the inner walls of the cavities on both sides of the extrusion block, and a pull rope is fixedly installed on the side wall of the extrusion block. The end of the pull rope away from the extrusion block passes around the guide rod and is fixedly connected to the connecting rod.

[0014] Preferably, the mounting box is rotatably mounted with multiple baffles, which are installed on the side of the sliding groove near the central axis of the roadway and are symmetrically arranged on both sides of the sliding groove.

[0015] Preferably, the bottom of the indicator component is provided with a flexible material.

[0016] Preferably, the bottom of the indicator component is made of a fluorescent material.

[0017] Preferably, the pull rope passes around the second guide roller and the first guide roller and is fixedly connected to the connecting rod, and the horizontal distance between the first guide roller and the push rod is greater than the horizontal distance between the second guide roller and the push rod.

[0018] Preferably, the support member is made of a flexible material.

[0019] Compared with the prior art, the present invention provides a deformation monitoring device for mines with faults, which has the following advantages:

[0020] 1. This invention utilizes the cooperation of multiple moving blocks and pressing blocks. When the roadway deforms, the cooperation of the moving blocks and pressing blocks causes the bottom of the indicating component to deform, thus alerting workers to the roadway deformation and providing additional support to the deformed area.

[0021] 2. By using the combination of ropes, connecting rods and support components, when the roadway deforms, the ropes, connecting rods and support components work together to allow other nearby components to provide additional support to the deformed area from the side, thereby dispersing the pressure at the deformed area and reducing the probability of component damage.

[0022] 3. By setting a baffle near the central axis of the roadway, when the roadway at the fault deforms and gangue falls simultaneously, the baffle near the central axis of the roadway discharges the falling gangue from both sides of the support, reducing the probability of gangue falling into the installation box and causing the components to jam, thus improving the stability of the device.

[0037] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0038] like Figures 1 to 9 As shown, this embodiment of the invention provides a deformation monitoring device for mines with faults, including a support 1, which is fixedly installed at the fault location in the roadway, with its top in contact with the top of the roadway, and also includes:

[0039] Monitoring component 2, mounted on support 1, is used to monitor deformation at the fault location;

[0040] Indicator component 3 is located at the end of support 1 away from the top of the roadway and is associated with monitoring component 2, used to indicate roadway deformation information based on monitoring results;

[0041] The monitoring component 2 includes a mounting box 21, which is mounted on the bracket 1. The mounting box 21 has a sliding groove 22, and a mounting plate 23 is slidably mounted in the sliding groove 22. Multiple support members 24 are fixedly mounted on the mounting plate 23. The mounting box 21 has a mounting cavity 25, and a connecting rod 26 is provided in the mounting cavity 25. One end of the connecting rod 26 is fixedly connected to the mounting plate 23. The monitoring component 2 and the indicator component 3 work together to enhance the monitoring and stabilization effect during deformation.

[0042] The working principle and beneficial effects of the above technical solution are as follows: the bracket 1 is installed in the required position and the top of the bracket 1 is tightly attached to the top of the tunnel. When the top of the tunnel deforms, it will squeeze the support member 24 on the mounting box 21, thereby driving the entire mounting box 21 to move downward. After the mounting box 21 moves downward, it will trigger the corresponding component in the indicator component 3 to provide support and stability to the deformed area from the vicinity of the deformed area.

[0043] In one embodiment: the support member 24 includes a bottom plate 241 and a top plate 242. A connecting rod 243 is fixedly installed between the bottom plate 241 and the top plate 242. A spring 244 is sleeved on the connecting rod 243. One end of the spring 244 is fixedly connected to the bottom plate 241, and the other end of the spring 244 is fixedly connected to the top plate 242. A support rod 245 is fixedly installed on the top plate 242. A support block 246 is fixedly installed at the end of the support rod 245 away from the top plate 242. The support block 246 is in contact with the top of the tunnel.

[0044] The working principle and beneficial effects of the above technical solution are as follows: when the support member 24 is squeezed by the top of the roadway, it will move downward to squeeze the support rod 245. When the support rod 245 moves, it will squeeze the spring 244 and the connecting rod 243. The connecting rod 243 is a telescopic rod. The buffering effect of the connecting rod 243 and the spring 244 reduces the damage of the first wave of impact to the entire device. Since there are multiple support members 24, when a support member 24 at a certain place is damaged by impact and cannot be used, other support members 24 on the same mounting plate 23 can, to a certain extent, take on its role.

[0045] In one embodiment: the mounting component 4 is provided in the groove of the bracket 1. The mounting component 4 includes a plurality of mounting grooves 41. Grooves 42 are symmetrically opened on both sides of the mounting grooves 41. A first guide roller 43 and a second guide roller 44 are rotatably mounted in the grooves 42. The first guide roller 43 and the second guide roller 44 are interleaved.

[0046] The working principle and beneficial effects of the above technical solution are as follows: The purpose of the staggered arrangement of the first guide roller 43 and the second guide roller 44 is to change the direction of the force. Since there are two symmetrically arranged grooves 42, there are also two sets of symmetrically arranged first guide rollers 43 and second guide rollers 44. Most existing monitoring devices are equipped with multiple identical and independent components to monitor different parts. However, when the adjacent parts are deformed, the stress at different locations is affected differently. When the stress acts on the independent components, interference may occur, resulting in poor monitoring effect. Under the action of the first guide roller 43 and the second guide roller 44, the adjacent support 24 can be moved towards the deformed area, which can achieve the effect of supporting and stabilizing the deformed area from the side.

[0047] In one embodiment: the indicating component 3 includes a cavity 31, a plurality of movable blocks 32 are slidably installed in the cavity 31, a pressing block 33 is abutted above the movable block 32, a push rod 34 is fixedly installed on the pressing block 33, and the end of the push rod 34 away from the pressing block 33 is fixedly connected to the mounting box 21.

[0048] The working principle and beneficial effects of the above technical solution are as follows: When the mounting box 21 moves, it will squeeze the push rod 34, thereby driving the squeezing block 33 to move downward, and then squeezing the moving block 32 to move to both sides. The reaction force of the moving block 32 can provide a certain support effect to the mounting box 21, reducing the probability of the roadway deformation continuing to deteriorate.

[0049] In one embodiment: guide rods 35 are symmetrically installed on the inner walls of the cavities 31 on both sides of the extrusion block 33, and a pull rope 36 is fixedly installed on the side wall of the extrusion block 33. The end of the pull rope 36 away from the extrusion block 33 passes around the guide rod 35 and is fixedly connected to the connecting rod 26.

[0050] The working principle and beneficial effects of the above technical solution are as follows: When the extrusion block 33 moves downward, it will drive the pull rope 36 to move synchronously. When the pull rope 36 moves downward, the direction of the force is changed by the guide rod 35, which will cause the connecting rod 26 connected to the other end of the pull rope 36 to move towards the center of the mounting box 21. Although the support area is reduced, the support strength is increased, so that the support member 24 on the mounting box 21 can withstand greater impact. At the same time, after the moving block 32 moves to both sides, it will cause the extrusion blocks 33 on both sides to move upward. Meanwhile, the pull rope 36 changes the direction of the force under the guidance of the guide rod 35, causing the support member 24 on both sides to move towards the deformation point. The originally independent extrusion blocks 33 can be combined into a whole, which can distribute the larger force at the deformation point to the surrounding components and reduce the probability of damage to individual components.

[0051] In one embodiment, a plurality of baffles 27 are rotatably mounted on the mounting box 21. The baffles 27 are installed on one side of the sliding groove 22 near the central axis of the roadway and are symmetrically arranged on both sides of the sliding groove 22.

[0052] The working principle and beneficial effects of the above technical solution are as follows: Although the top of the roadway at the fault is relatively broken, when deploying the monitoring device, a relatively intact position is usually selected. At this time, there is no need to set baffle 27 on the mounting box 21. However, not all roadways can find an ideal and intact deployment position. When the roadway top is in poor condition and the degree of breakage is high, baffle 27 needs to be added to the mounting box 21. When the roadway deforms, the broken roadway top will easily cause gangue to fall. When the falling gangue comes into contact with the baffle 27, it will be discharged from both sides of the support 1 along the inclined baffle 27, reducing the probability of gangue falling into the mounting box 21 and causing the component to jam, thus improving the stability of the device.

[0053] In one embodiment, the bottom of the indicator component 3 is provided with a flexible material.

[0054] The working principle and beneficial effects of the above technical solution are as follows: The bottom of the indicator component 3 is composed of a flexible part and a rigid part. The rigid part is made of a high-strength alloy material and is in the shape of a frame. The flexible part is wrapped between the rigid part frame. The flexible part can be made of a rubber material with a certain thickness. When the extrusion block 33 moves to a certain extent, it will squeeze the flexible part outward. By observing the deformation of the flexible part, the deformation of the top of the tunnel can be understood.

[0055] In one embodiment, the bottom of the indicator component 3 is made of a fluorescent material.

[0056] The working principle and beneficial effects of the above technical solution are as follows: Since the lighting environment in the tunnel is not very good, by setting up the indicator component 3 made of fluorescent material, it is easier for the staff to observe the deformation of the flexible part of the indicator component 3, thereby improving the recognizability.

[0057] In one embodiment: the pull rope 36 passes around the second guide roller 44 and the first guide roller 43 and is fixedly connected to the connecting rod 26, and the horizontal distance between the first guide roller 43 and the push rod 34 is greater than the horizontal distance between the second guide roller 44 and the push rod 34.

[0058] The working principle and beneficial effects of the above technical solution are as follows: by setting a first guide roller 43 and a second guide roller 44 at different horizontal distances from the push rod 34, it is ensured that when deformation occurs at the top of a certain roadway, the lateral support 24 will move towards the deformation position, thus avoiding the situation where the support 24 at the deformation point moves away from the deformation point.

[0059] In one embodiment, the support member 24 is made of a flexible material.

[0060] The working principle and beneficial effects of the above technical solution are as follows: the material of the support component 24 can be selected according to the specific conditions of the tunnel, and the material can be selected as high-strength resin or high-molecular composite fiber.

[0061] Working principle and usage process: Install the bracket 1 in the required position and fit the top of the bracket 1 tightly against the top of the tunnel. When the top of the tunnel deforms, it will squeeze the support 24 on the mounting box 21, thereby driving the entire mounting box 21 to move downward. After the mounting box 21 moves downward, it will trigger the corresponding component in the indicator component 3, which will provide support and stability to the deformed area from the vicinity of the deformed area.

[0062] When the support member 24 is squeezed by the top of the tunnel, it will move downward to squeeze the support rod 245. When the support rod 245 moves, it will squeeze the spring 244 and the connecting rod 243. The connecting rod 243 is a telescopic rod. The buffering effect of the connecting rod 243 and the spring 244 reduces the damage of the first wave of impact to the entire device. Since there are multiple support members 24, if a support member 24 at a certain point is damaged by impact and cannot be used, other support members 24 on the same mounting plate 23 can, to a certain extent, take over its role.

[0063] Based on the above, when the mounting box 21 moves, it will squeeze the push rod 34, thereby driving the squeezing block 33 to move downward, and then squeezing the moving block 32 to move to both sides. The reaction force of the moving block 32 can provide a certain support effect to the mounting box 21, reducing the probability of the roadway deformation continuing to deteriorate.

[0064] In addition, the purpose of the staggered arrangement of the first guide roller 43 and the second guide roller 44 is to change the direction of the force. Since there are two symmetrically arranged grooves 42, there are also two sets of symmetrically arranged first guide rollers 43 and second guide rollers 44. Most existing monitoring devices are equipped with multiple identical and independent components to monitor different parts. However, when the adjacent parts are deformed, the stress at different locations will have different effects. When acting on independent components, interference may occur, resulting in poor monitoring effect. Under the action of the first guide roller 43 and the second guide roller 44, the adjacent support 24 can be moved towards the deformed area, which can achieve the effect of supporting and stabilizing the deformed area from the side.

[0065] Furthermore, when the compression block 33 moves downward, it will drive the pull rope 36 to move synchronously. When the pull rope 36 moves downward, the direction of the force is changed by the guide rod 35, causing the connecting rod 26 connected to the other end of the pull rope 36 to move towards the center of the mounting box 21. Although the support area is reduced, the strength of the support is increased, allowing the support member 24 on the mounting box 21 to withstand greater impact. At the same time, after the moving block 32 moves to both sides, it will cause the compression blocks 33 on both sides to move upward. Meanwhile, the pull rope 36 changes the direction of the force under the guidance of the guide rod 35, causing the support member 24 on both sides to move towards the deformation point. This can combine the originally independent compression blocks 33 into a whole, allowing the larger force at the deformation point to be distributed to the surrounding components, reducing the probability of damage to individual components.

[0066] Although the top of the roadway at the fault is relatively broken, most monitoring devices are installed in relatively intact locations. In such cases, there is no need to install baffles 27 on the mounting box 21. However, not all roadways can find ideal, intact installation locations. When the roadway top is in poor condition and highly broken, baffles 27 need to be installed on the mounting box 21. When the roadway deforms, gangue can easily fall from the broken roadway top. When the falling gangue comes into contact with baffles 27, it will be discharged from both sides of the support 1 along the inclined baffles 27, reducing the probability of gangue falling into the mounting box 21 and causing the components to jam, thus improving the stability of the device.

[0067] Finally, the bottom of the indicator component 3 is composed of a flexible part and a rigid part. The rigid part is made of a high-strength alloy material and is frame-shaped. The flexible part is wrapped between the rigid part frame. The flexible part can be made of rubber material with a certain thickness. When the extrusion block 33 moves to a certain extent, it will squeeze the flexible part outward. By observing the deformation of the flexible part, the deformation of the top of the tunnel can be understood. In addition, since the lighting environment in the tunnel is not very good, by setting the indicator component 3 with fluorescent material, it is easier for the staff to observe the deformation of the flexible part of the indicator component 3, thus improving the visibility.

[0068] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
