Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to a device for detecting roof deformation in non-coal mine tunnels. Background Art

[0002] Mine tunnels are a vital underground passage system in mining. Like the veins of the human body, they are crisscrossed inside the mine, connecting various mining areas and workplaces. From a functional point of view, they are mainly divided into transport tunnels, ventilation tunnels and pedestrian tunnels. Transport tunnels are responsible for the transportation of ore, equipment and materials, and are the "arteries" of mine production. By laying tracks or using trackless transportation equipment, resources are ensured to be transported out continuously. Ventilation tunnels are responsible for introducing fresh air and exhausting polluted gases, maintaining good air quality and suitable temperature and humidity underground, and creating a safe and healthy working environment for miners, just like the human respiratory system. Pedestrian tunnels provide miners with a safe passage to facilitate their movement between different work sites, and are also important escape routes in emergencies. The rational planning and construction of mine tunnels are directly related to the efficiency, safety and sustainability of mine mining, and are an indispensable basic component of modern mining operations.

[0003] Mine tunnels are basic projects completed at the beginning of a mine. The role of mine tunnels is not just to transport mineral resources, mining equipment and staff. Mine tunnels also carry important tasks such as ventilation exchange between the inside and outside of the mine and the discharge of harmful gases inside the mine. Therefore, tunnels inside non-coal mines are generally opened along the distribution of mineral resources. Therefore, tunnels inside non-coal mines are generally tortuous, not straight. In order to ensure the normal and safe mining of mines, the detection of tunnel roof is of paramount importance. Existing detection equipment is generally installed vertically. This installation method not only affects the normal use of mine tunnels, but also has poor detection effect. It can only detect the deformation of the middle part of the roof, and cannot make sufficient predictions on the safe use of mine tunnels. Moreover, existing detection equipment cannot perform normal detection and use for tunnels with a high degree of curvature. Therefore, technical personnel in this field have proposed a non-coal mine tunnel roof deformation detection device to solve the above-mentioned technical problems. Summary of the invention

[0013] Working principle: When conducting deformation detection on some winding tunnel roofs in some non-coal mines, the fixing mechanism is first installed and started. The staff moves multiple sets of equipment required for mine tunnel detection into the tunnel and places the equipment equidistantly. Then the staff installs multiple sets of equipment in the mine tunnel. First, the staff lifts or supports the top seat to fit it with the tunnel roof, and adjusts the horizontal effect of the overall device through the level bubble on the top seat during the fitting process. Then, after the top seat is adjusted horizontally, the staff uses an electric drill and other equipment to rotate it through the cross slot on the tightening adjustment seat. When the cross slot drives the tightening adjustment seat at the bottom of the top seat to rotate, the tightening adjustment seat drives the threaded anchor rod in the top seat to rotate synchronously. While the threaded anchor rod rotates, its top and the moving ring seat on it penetrate into the interior of the tunnel roof, and then as the threaded anchor rod keeps moving, The movable ring seat on the threaded anchor rod rotates, and the movable ring seat on the threaded anchor rod gradually begins to move downward, and the movable ring seat drives the outer support plate 1 on it to move downward and open synchronously while moving downward, and the outer support plate 1 moves downward and opens while it also drives the outer support plate 2 at its bottom to move downward and open by rotating the connecting rod simultaneously, so that the outer support plate 1 and the outer support plate 2 after moving downward and opening form a triangular shape inside the tunnel roof to support the entire device, and as the outer support plate 2 continues to move upward, the bottom of the outer support plate 2 drives the mounting seat 1 to move upward synchronously, and the mounting seat 1 drives the top seat to fit with the tunnel roof while moving upward, and as the top seat continues to move upward, the top of the top seat contacts with the top plate, thereby squeezing the silicone coating on the top seat to deform, and the gap generated between the top seat and the surface of the top plate is filled by the silicone coating after deformation, thereby ensuring the fit of the entire device with the tunnel roof during the installation and fixing process, thereby completing the installation and fixing of the entire device;Then the top wall detection mechanism is started. After the installation and fixing mechanism fixes the equipment on the top seat to the tunnel roof, the staff manually adjusts the turntable seat on the alarm signal transmitter, so that the laser transmitter on the mounting column of the tunnel source part is adjusted to the position facing the inside of the tunnel. Then the laser transmitter on the mounting column of the equipment in the middle part of the tunnel is adjusted to the position of the receiving seat, and the laser emitted by the laser receiver of the source part is received and refracted. After that, the laser receiver on the mounting column of the equipment at the end of the tunnel can be adjusted to a position where it can receive the laser, thereby completing the equipment. After the adjustment before use, the staff turns on the laser transmitter installed on the column at the source of the tunnel, so that it emits laser light. Then the laser transmitters at various positions on the roof all emit laser light to form a detection network at the roof position. The emitted laser light is then received and refracted by the receiving seats installed on the columns at various positions in the tunnel, so that the laser light reaches the position at the end of the tunnel. When the local tunnel roof is deformed, the deformed part of the tunnel roof blocks the laser light emitted by the laser transmitter, so that the laser receiver at the corresponding position cannot receive the laser signal. The alarm signal transmitter at the corresponding position of the rear tunnel sends out an alarm and transmits the alarm signal to the control center to complete the deformation detection and processing of the tunnel roof; at the same time, the side wall linkage mechanism is started, and after the equipment on the top seat is installed, the staff will fit the metal bonding plates on both sides of the top seat with the tunnel side walls, and then use the socket holes on the metal bonding plates to match the fixed anchor rods inside them to fix the metal bonding plates on the tunnel side walls, and then respectively plug the two ends of the conductive support rod into the socket two on the connecting seat and the socket one at the bottom of the top seat. When the tunnel side walls are deformed, the tunnel side walls become The corresponding area on the metal laminated plate is deformed by the shaped part, and then the area base on the deformed area is also displaced synchronously. When the area base is displaced, it drives the connecting seat to move synchronously through the supporting connecting rod. During the movement, the connecting seat impacts the plug-in seat at the bottom of the top seat through the conductive supporting rod, so that the plug-in seat drives the top seat to produce displacement changes. After the displacement change, the top seat cannot receive or refract the laser emitted at the source position of the tunnel, so that the alarm signal transmitter on the top seat in this area sends a warning signal, thereby completing the linkage detection processing of the side wall of the tunnel;When facing a winding lane, the deformation adjustment mechanism is activated, the laser transmitter on the mounting column at the source of the lane is adjusted to the position facing the inside of the lane, the receiving seat on the equipment mounting column in the middle of the lane is adjusted to the angle that can receive the laser emitted by the previous device, and the laser receiver on the equipment mounting column at the end of the lane is adjusted to the angle that can receive the laser emitted by the previous device. After the laser emitted by the source device is received by the device at the middle of the lane, the laser passes through the anti-reflection film on the rotating groove to reduce the reflection loss, and the laser intensity is enhanced at the same time. Then, the enhanced laser enters the inner prism groove and is refracted again by the prism combination in the inner prism groove, so that the laser reaches the position of the next device. Finally, the laser after multiple refractions is received by the laser receiver on the mounting column at the end of the lane, so as to meet the deformation detection of the curved lane. ;

[0014] The present invention provides a device for detecting roof deformation in non-coal mine tunnels. It has the following beneficial effects: 1. The present invention adds and sets an installation and fixing mechanism. During the installation process, its unique design can fit closely to the complex surface of the tunnel roof. Through multi-point support and a stable anchoring structure, it can effectively resist vibration and impact in the tunnel and local deformation of the roof, greatly ensuring the installation stability of the overall detection device and reducing the risk of detection error caused by loose installation. At the same time, during the long-term use of the detection device, the horizontal calibration component equipped by the mechanism can continuously keep the device in a precise horizontal state, ensuring the accuracy and reliability of the detection data, and providing a solid guarantee for the safe monitoring of the mine tunnel roof.

[0015] 2. The present invention increases and sets a top wall detection mechanism, which detects the state of the tunnel top wall by means of laser. This detection method not only does not affect the normal use of the tunnel, thereby ensuring the normal use of the mine tunnel and the continuity of production, but also forms a detection network for the tunnel roof through multiple laser rays during the detection process, which can comprehensively detect various positions of the tunnel roof, comprehensively and efficiently grasp the real-time status of the roof, and provide solid and reliable technical support for timely discovery of hidden dangers and prevention of roof accidents, and effectively guarantee the safety and stability of mine operations.

[0016] 3. The present invention adds and sets a side wall linkage mechanism. When the mechanism is in use, it not only provides a stable and reliable support for the detection equipment of the tunnel roof, effectively reduces the detection error caused by the shaking or displacement of the equipment, ensures the accuracy of the roof monitoring data, and builds the first line of defense to prevent roof collapse accidents, but also the mechanism has the ability to detect the deformation of the side of the tunnel, so that the detection equipment can also capture the subtle changes of the side rock wall in time, thereby making sufficient predictions and suggestions for the safe use of the mine tunnel, so as to take countermeasures at the first time, ensuring the stability of the entire tunnel structure, and at the same time, the mechanism can also provide a solid safety guarantee for the normal mining operation of the mine, ensuring that the mining work is carried out smoothly and efficiently.

[0017] 4. The present invention adds and sets a deformation adjustment mechanism. In the mine tunnel environment, especially the curved tunnel, the mechanism can not only accurately receive and detect laser light during use, but also cleverly enhance the light intensity through the combination of prism array and anti-reflection film, overcome the attenuation problem of light during transmission, and then after the laser light is received and enhanced, the refraction device guides the light to propagate along the curved tunnel wall to ensure that the laser detection covers all key parts of the tunnel. This not only greatly improves the prism of the overall device under complex tunnel conditions, but also provides more comprehensive and accurate data support for the safety monitoring of mine tunnels, and effectively guarantees the stability and safety of mining operations.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please see attached Figure 1 - Attachment Figure 3 , an embodiment of the present invention provides a device for detecting deformation of a roof of a non-coal mine tunnel, including a top seat 1, which is a basic component of the overall device and is used to assemble and carry various processing mechanisms and their subordinate structural parts; When the overall device is in use, more than two devices must be used in combination. When multiple devices are used in combination, they can be installed equidistantly in the mine tunnel, and then the equipment can be flexibly adjusted according to the depth of the mine tunnel and the curvature of the tunnel.

[0022] Please see attached Figure 4 - Attachment Figure 5 , an installation and fixing mechanism is arranged on the top of the top seat 1, and is used to install and fix the whole device and the roof of the mine tunnel; The installation and fixing mechanism includes a tightening adjustment seat 31, a plurality of tightening adjustment seats 31 are equidistantly connected to the middle of the bottom end of the top seat 1, a silicone coating 3 is provided in the middle of the top end of the tightening adjustment seat 31, a plurality of mounting seats 2 are equidistantly fixedly connected to the top end of the top seat 1, and the top end of the mounting seat 2 passes through the corresponding position of the silicone coating 3 and extends outward, a plurality of threaded anchor rods 4 are equidistantly connected to the inside of the top seat 1, and the top end of the threaded anchor rod 4 passes through the corresponding position of the mounting seat 2 and extends outward, the bottom end of the threaded anchor rod 4 is connected to the middle of the tightening adjustment seat 31 at the corresponding position, a cross groove 14 is provided in the middle of the bottom end of the tightening adjustment seat 31, and a level bubble 8 is provided in the middle of the front side of the top seat 1.

[0023] When the installation and fixing mechanism is started, the staff moves multiple sets of equipment required for mine tunnel inspection into the tunnel and places the equipment equidistantly. Then the staff installs the multiple sets of equipment in the mine tunnel. First, the staff lifts or supports the top seat 1 to fit it with the tunnel roof, and adjusts the horizontal effect of the overall device through the level bubble 8 on the top seat 1 during the fitting process.

[0024] Then, after the horizontal adjustment of the top seat 1 is completed, the staff rotates the cross groove 14 on the tightening adjustment seat 31 through an electric drill or other equipment. When the cross groove 14 drives the tightening adjustment seat 31 at the bottom of the top seat 1 to rotate, the tightening adjustment seat 31 drives the threaded anchor rod 4 in the top seat 1 to rotate synchronously. While the threaded anchor rod 4 rotates, its top end and the movable ring seat 23 thereon penetrate into the interior of the tunnel roof. Then, as the threaded anchor rod 4 rotates continuously, the movable ring seat 23 on the threaded anchor rod 4 gradually begins to move downward. While the movable ring seat 23 moves downward, it drives the outer support plate 7 thereon to move downward and open synchronously. While the outer support plate 7 moves downward and opens, it also drives the outer support plate 29 at the bottom thereof to move downward and open synchronously by rotating the connecting rod 22, so that the outer support plate 7 and the outer support plate 29 after moving downward and opening form a triangular shape inside the tunnel roof to support and fix the entire device.

[0025] The installation and fixing mechanism also includes a movable ring seat 23, the middle and upper parts of the threaded anchor rod 4 are rotatably connected to the movable ring seat 23, the middle parts of the front and rear sides of the movable ring seat 23 are rotatably connected to the outer support plate 7, the end of the outer support plate 7 away from the movable ring seat 23 is rotatably connected to the rotating connecting rod 22, the top middle part of the mounting seat 2 is rotatably connected to the outer support plate 29 on both sides, and the end of the outer support plate 29 away from the mounting seat 2 is respectively connected to the corresponding rotating connecting rod 22.

[0026] As the outer support plate 29 continues to move upward, the bottom of the outer support plate 29 drives the mounting seat 2 to move upward synchronously. While moving upward, the mounting seat 2 drives the top seat 1 to fit with the top plate of the tunnel. As the top seat 1 continues to move upward, the top of the top seat 1 contacts the top plate, thereby squeezing the silicone coating 3 on the top seat 1 to deform. The deformed silicone coating 3 fills the gap between the top seat 1 and the surface of the top plate, thereby ensuring the fit of the entire device with the top plate of the tunnel during the installation and fixation process, thereby completing the installation and fixation of the entire device.

[0027] Please see attached Figure 3 and attached Figure 6 , a top wall detection mechanism, which is arranged at the bottom of the top seat 1 and is used to detect deformation of the top wall of the mine tunnel roof; The top wall detection mechanism includes an alarm signal transmitter 13. A plurality of alarm signal transmitters 13 are equidistantly arranged in the middle of the bottom end of the top seat 1. A turntable seat 19 is rotatably provided in the middle of the bottom end of the alarm signal transmitter 13. A mounting column 17 is fixedly connected to the middle of the bottom end of the turntable seat 19. A plurality of angle identification seats 24 are arranged in a circular array near the edge of the bottom end of the alarm signal transmitter 13.

[0028] When the top wall detection mechanism is started, after the installation and fixing mechanism fixes the equipment on the top seat 1 to the tunnel roof, the staff manually adjusts the turntable seat 19 on the alarm signal transmitter 13, so that the laser transmitter 15 on the mounting column 17 of the tunnel source part is adjusted to a position facing the inside of the tunnel, and then the laser transmitter 15 on the mounting column 17 of the equipment in the middle part of the tunnel is adjusted to the position of the receiving seat 21 to receive and refract the laser emitted by the laser receiver 16 of the source part, and then the laser receiver 16 on the mounting column 17 of the equipment at the tail of the tunnel can be adjusted to a position where it can receive the laser, thereby completing the adjustment of the equipment before use.

[0029] The top wall detection mechanism also includes a mounting seat 20, and the middle part of the outer wall of the mounting column 17 is arranged with a first mounting seat 20, a second mounting seat 20 and a third mounting seat 20 in a counterclockwise circle. The middle part of the first mounting seat 20 is provided with a laser transmitter 15, and the middle part of the second mounting seat 20 is provided with a laser receiver 16.

[0030] After that, the staff turns on the laser emitter 15 on the mounting column 17 at the source of the tunnel, so that it emits laser light. Then, the laser emitters 15 at various positions on the roof all emit laser light to form a detection network at the roof position. Then, the emitted laser light is received and refracted by the receiving seat 21 on the mounting column 17 at various positions of the tunnel, so that the laser light reaches the position at the tail end of the tunnel to be repaired. When the local tunnel roof is deformed, the deformed part of the tunnel roof blocks the laser light emitted by the laser emitter 15, so that the laser receiver 16 at the corresponding position cannot receive the laser signal. Then, the alarm signal transmitter 13 at the corresponding position of the tunnel issues an alarm and transmits the alarm signal to the control center, thereby completing the deformation detection process of the tunnel roof.

[0031] Please see attached Figure 7 , a side wall linkage mechanism, which is arranged on both sides of the top seat 1, and is used for linkage detection and processing of the side walls of the mine tunnel; The side wall linkage mechanism includes a metal bonding plate 10. The metal bonding plates 10 are arranged in the middle of both sides of the top seat 1. Plug holes 26 are opened at the four corners of the metal bonding plate 10. Fixed anchor rods 6 are arranged in the plug holes 26. A plurality of area bases 25 are equidistantly arranged on one side of the metal bonding plate 10 close to the top seat 1. The area bases 25 divide the metal bonding plates 10 at the corresponding positions into a plurality of areas of the same size.

[0032] When the side wall linkage mechanism is started, after the equipment on the top seat 1 is installed, the staff will fit the metal bonding plates 10 on both sides of the top seat 1 with the side walls of the tunnel, and then use the plug holes 26 on the metal bonding plates 10 to cooperate with the fixed anchor rods 6 therein to fix the metal bonding plates 10 on the side walls of the tunnel, and then respectively plug the two ends of the conductive support rod 12 into the plug socket 2 32 on the connecting seat 5 and the plug socket 1 18 at the bottom of the top seat 1.

[0033] The side wall linkage mechanism also includes a connecting seat 5, a connecting seat 5 is provided in the middle of one side of the metal bonding plate 10, a supporting connecting rod 11 is provided in the middle of the area base 25, and the end of the supporting connecting rod 11 away from the metal bonding plate 10 is respectively connected to the corresponding position of the connecting seat 5, the middle of the side of the connecting seat 5 away from the metal bonding plate 10 is fixedly connected with a plug-in seat 2 32, the middle of both sides of the bottom end of the top seat 1 is fixedly connected with a plug-in seat 18, a conductive support rod 12 is provided in the plug-in seat 18, and the other end of the conductive support rod 12 extends to the corresponding plug-in seat 2 32.

[0034] When the side wall of the tunnel is deformed, the deformed part of the side wall of the tunnel squeezes the corresponding area on the metal laminate plate 10 to produce deformation, and then the area base 25 on the deformed area also produces displacement synchronously. While the area base 25 is displaced, it drives the connecting seat 5 to move synchronously through the supporting connecting rod 11. During the movement, the connecting seat 5 impacts the plug-in seat 18 at the bottom of the top seat 1 through the conductive support rod 12, so that the plug-in seat 18 drives the top seat 1 to produce displacement change. After the displacement change, the top seat 1 cannot receive or refract the laser emitted at the source position of the tunnel, so that the alarm signal transmitter 13 on the top seat 1 in this area sends a warning signal, thereby completing the linkage detection processing of the side wall of the tunnel.

[0035] Please see attached Figure 8 - Attachment Fig. 9 , a deformation adjustment mechanism is arranged at the bottom of the top seat 1 and is used to perform corresponding deformation adjustment processing when detecting non-linear mine tunnels.

[0036] The deformation adjustment mechanism includes a receiving seat 21. The receiving seat 21 is arranged in the middle of the third mounting seat 20. A screw-on groove 29 is provided on the side of the receiving seat 21 away from the third mounting seat 20. An anti-reflection film 27 is threadedly connected in the screw-on groove 29. An inner prism groove 30 is provided in the middle of the receiving seat 21. A prism assembly 28 is arranged inside the inner prism groove 30.

[0037] When the deformation adjustment mechanism is activated, the laser transmitter 15 on the mounting column 17 at the source position of the tunnel is adjusted to a position facing the inside of the tunnel, and the receiving seat 21 on the equipment mounting column 17 in the middle of the tunnel is adjusted to an angle that can receive the laser emitted by the previous device, and the laser receiver 16 on the equipment mounting column 17 at the end of the tunnel is adjusted to an angle that can receive the laser emitted by the previous device. After the laser emitted by the source device is received by the device at the middle position of the tunnel, the laser passes through the anti-reflection film 27 on the screw-on groove 29 to reduce reflection loss.

[0038] At the same time, the laser intensity is enhanced, and then the enhanced laser enters the inner groove 30, and is refracted again by the prism combination 28 in the inner groove 30, so that the laser reaches the position of the next device, and finally the laser after multiple refractions is received by the laser receiver 16 on the mounting column 17 at the end of the tunnel, so as to meet the deformation detection of the curved tunnel.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
