Description

Technical Field

[0001] This invention relates to the field of laser monitoring technology, and in particular to laser monitoring equipment for underground support deformation in mines. Background Technology

[0002] In mining, the shafts, tunnels, and chambers that need to be excavated are collectively referred to as mine shafts and tunnels. Underground support is of great significance for maintaining the smooth flow of tunnels and the stability of surrounding rock in metal mine construction and production. Traditional underground support is usually an "n"-shaped support frame. In order to improve safety, it is necessary to monitor the deformation of the support.

[0003] For example, Chinese invention patent CN119879763A discloses a laser monitoring device for deformation of underground mine support. Specifically, it includes a main mounting frame and a secondary mounting frame. The main mounting frame is sequentially installed on the surface of the main support frame of the underground mine, and the secondary mounting frame is sequentially installed on the surface of the support connecting plate. The main and secondary mounting frames are spaced apart. A monitoring tube is installed at the bottom of the secondary mounting frame, and two parallel monitoring cavities are arranged on both sides of the monitoring tube. In this invention, the monitoring tube is installed on the support connecting plate via the secondary mounting frame, making installation simple and convenient. This facilitates the modification of existing underground support structures, and the monitoring scheme is easy to implement according to the roadway direction, reducing the cost of monitoring roadway support deformation. Furthermore, the monitoring tube isolates the monitoring laser beam from the roadway environment, preventing the beam from being affected by the roadway environment and reducing the accuracy and timeliness of monitoring.

[0004] However, the aforementioned invention patent still has defects. It uses point laser to monitor support deformation, which has a limited range of deformation monitoring. Furthermore, since the deformation amplitude of the support is often small, it is difficult to monitor accurately. At the same time, the installation error of the support and construction vibration can easily affect the monitoring accuracy. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies that use point lasers to monitor support deformation, which have a limited range of deformation monitoring, and are difficult to monitor accurately due to the small magnitude of support deformation. Furthermore, installation errors and construction vibrations can easily affect the monitoring accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laser monitoring device for deformation of underground mine support, comprising a guide rail, a base, a gantry frame, and a track climber. Two guide rails are provided and laid along the roadway. An inspection railcar is fixedly installed at the bottom of the base to drive the base to move along the guide rails. The gantry frame is installed on top of the two bases. A connecting seat is fixedly installed at the bottom of the gantry frame, and a first laser rangefinder is fixedly installed on the connecting seat to assist in calibrating the position of the base. Sliding grooves are provided on both sides of the gantry frame. The track climber is slidably installed on the gantry frame through the sliding grooves and slides along the gantry frame to monitor deformation. The device also includes: A calibration assembly mounted on top of the base is used to connect the gantry frame; A monitoring component installed on the track climber is used to monitor the deformation of the support frame.

[0007] In at least some embodiments, the correction assembly includes a vertical plate and a slide rail. Two vertical plates are fixedly mounted on the top of a base. A guide rod is fixedly mounted between the two vertical plates. The slide rail is slidably fitted onto the guide rod. A first lead screw is rotatably mounted between the two vertical plates. The slide rail is threadedly adapted to the first lead screw. Rotation of the first lead screw causes the slide rail to slide on the guide rod. A second lead screw is rotatably mounted on the slide rail. A driven bevel gear is fixedly mounted at one end of the second lead screw. A drive shaft is rotatably mounted between the two vertical plates. A bushing is fixedly welded to the slide rail and movably fitted onto the drive shaft. A driving bevel gear, meshing with the driven bevel gear, is rotatably fitted onto the bushing. A transverse sliding seat is slidably mounted on the slide rail and threadedly adapted to the second lead screw. Rotation of the second lead screw causes the transverse sliding seat to slide on the slide rail.

[0008] In at least some embodiments, the drive shaft has multiple protruding ridges arranged in a circular array, and the bushing on the slide rail has a groove that fits the protruding ridges. When the drive shaft rotates, it will not interfere with the lateral movement of the slide rail.

[0009] In at least some embodiments, two motors are fixedly installed on the upright plate, which respectively drive the slide rail and the transverse moving seat to move laterally, and the transverse moving direction of the slide rail and the transverse moving seat are perpendicular to each other on the horizontal plane.

[0010] In at least some embodiments, the monitoring component includes a mounting base and a second laser rangefinder. A lifting seat is longitudinally slidably mounted on the track climber. An electric actuator is fixedly mounted inside the track climber, and the telescopic end of the electric actuator is fixedly connected to the lifting seat. The telescopic extension of the electric actuator drives the lifting seat to rise and fall to prevent interference between the lifting seat and the support frame. The mounting base is fixedly mounted on the lifting seat. A hanging shaft is fixedly mounted on the mounting base. Multiple levers are rotatably mounted on the hanging shaft at equal intervals. Multiple probes are movably inserted into the top of the mounting base. A ball joint is fixedly mounted on one end of each probe. Multiple insert rods are movably inserted into the side of the mounting base corresponding to the lever positions. A reflector is fixedly mounted on one end of each insert rod, and a stop plate is fixedly mounted on the other end.

[0011] In at least some embodiments, the lever is Z-shaped with the shorter segment being the input lever and the longer segment being the output lever. The probe rod is fixedly connected to the input lever arm, and a return spring is fixedly connected between the abutment and the mounting base. Under the elastic force of the return spring, the abutment is pressed tightly against the output lever arm to amplify the travel of the probe rod.

[0012] In at least some embodiments, a piston rod is fixedly mounted on the abutment, and a piston is fixedly mounted on the other end of the piston rod. A dustproof box is fixedly mounted on one side of the mounting base. A liquid storage tank is fixedly mounted on the dustproof box, and fluorescent liquid is added to the liquid storage tank. Piston cylinders are fixedly inserted at equal intervals on the mounting base. The piston is movably inserted into the piston cylinder. The piston cylinder is provided with an inlet and an outlet. The inlet of the piston cylinder is fixedly connected to the liquid storage tank. A hose is fixedly connected to the outlet of the piston cylinder, and a nozzle is fixedly mounted on the other end of the hose. A fixing plate for fixing the nozzle is fixedly mounted on the detection rod.

[0013] In at least some embodiments, a one-way valve is installed on both the inlet and outlet of the piston cylinder. The one-way valve at the inlet of the piston cylinder allows for one-way flow into the piston cylinder, while the one-way valve at the outlet of the piston cylinder allows for one-way flow to the outside of the piston cylinder.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, the monitoring components are driven by a base that can move along the guide rail and a rail climber that can move along the gantry to achieve continuous and large-scale scanning monitoring of the downhole support structure. Furthermore, the design of multiple probe rods in the monitoring components overcomes the shortcomings of the limited range of traditional point laser monitoring, significantly improving monitoring efficiency and coverage.

[0015] 2. In this invention, by setting a calibration component, the position of the gantry can be accurately calibrated in the early stages of installation and inspection, effectively eliminating installation errors and system errors caused by minor deformations of the equipment due to long-term use.

[0016] 3. In this invention, the monitoring component utilizes a "Z"-shaped lever mechanism to convert the minute linear displacement of the probe rod caused by the support deformation into an amplified displacement at the end of the insertion rod, which plays a role in mechanical amplification. This makes the equipment highly sensitive to micro-deformation and accurately capture potential risks.

[0017] 4. In this invention, an innovative automatic marking system based on a piston cylinder and fluorescent liquid is designed. When deformation exceeding the threshold is detected, the equipment can automatically spray fluorescent liquid on the deformation location to achieve visualization and precise positioning of the deformation point. This greatly facilitates the rapid identification and handling of hidden dangers by underground maintenance personnel and improves the efficiency and response speed of mine safety management.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Implementation examples, based on Figures 1-8 ,like Figure 1 As shown, the laser monitoring equipment for underground mine support deformation provided in this embodiment of the invention includes a guide rail 1, a base 2, a gantry frame 3, and a rail climber 5. Two guide rails 1 are provided and laid along the roadway, as shown... Figure 2 As shown, an inspection railcar 201 is fixedly installed at the bottom of the base 2 to drive the base 2 to move along the guide rail 1. The gantry frame 3 is installed on top of the two bases 2, as shown. Figure 3 As shown, a connecting seat 301 is fixedly installed at the bottom of the gantry frame 3, and a first laser rangefinder 302 is fixedly installed on the connecting seat 301 to assist in calibrating the position of the base 2. Slide grooves are provided on both sides of the gantry frame 3, and the track climber 5 is slidably installed on the gantry frame 3 through the slide grooves and slides along the gantry frame 3 to monitor deformation. It also includes a correction component 4 installed on the top of the base 2 to connect the gantry frame 3, and a monitoring component 6 installed on the track climber 5 to monitor the deformation of the support frame.

[0023] like Figure 4 As shown, the correction assembly 4 includes a vertical plate 401 and a slide rail 402. Two vertical plates 401 are fixedly mounted on the top of the base 2. A guide rod 403 is fixedly mounted between the two vertical plates 401. The slide rail 402 is slidably fitted onto the guide rod 403. A first lead screw 404 is rotatably mounted between the two vertical plates 401. The slide rail 402 is threadedly fitted to the first lead screw 404. The rotation of the first lead screw 404 drives the slide rail 402 to slide on the guide rod 403. A second lead screw 406 is rotatably mounted on the slide rail 402. A driven bevel gear 407 is fixedly mounted at one end of the second lead screw 406. A drive shaft 405 is rotatably mounted between the two vertical plates 401. A bushing is fixedly welded to the slide rail 402 and movably fitted onto the drive shaft 405. On shaft 405, a drive bevel gear 408 is rotatably mounted on a bushing and meshes with a driven bevel gear 407. A transverse sliding seat 409 is slidably mounted on slide rail 402 and is threadedly matched with a second lead screw 406. The rotation of the second lead screw 406 drives the transverse sliding seat 409 to slide on slide rail 402. Multiple protruding ribs are arranged in a ring array on drive shaft 405. A groove matching the protruding ribs is opened in the bushing on slide rail 402. When drive shaft 405 rotates, it will not interfere with the transverse movement of slide rail 402. Two motors are fixedly mounted on vertical plate 401 to drive the transverse movement of slide rail 402 and transverse sliding seat 409 respectively. The transverse movement direction of slide rail 402 and transverse movement direction of transverse sliding seat 409 are perpendicular to each other on the horizontal plane. In the underground roadway, two guide rails 1 are first laid parallel to the bottom of the roadway. The base 2 is mounted on the guide rails 1 via the inspection railcar 201 at its bottom. The gantry frame 3 is installed on top of the two bases 2 via the correction assembly 4. During installation, the two motors in the correction assembly 4 are controlled to drive the first lead screw 404 and the drive shaft 405 to rotate, thereby causing the slide rail 402 to be finely adjusted in the Y-axis (perpendicular to the roadway direction) and the transverse seat 409 in the X-axis (along the roadway direction) direction. This ensures that the gantry frame 3 is precisely adjusted to be parallel to the roadway support structure. After adjustment, the gantry frame 3 is firmly installed on the transverse seat 4. On the 09, a laser receiver with a laser reflector 609 is installed between adjacent support frames. During the movement of the gantry 3, a laser is emitted by the first laser rangefinder 302 on the side and received by the laser receiver to achieve automatic positioning. This ensures that the gantry 3 stops between the two support frames to detect deformation of the two support frames. At the same time, the laser is reflected by the laser reflector 609 on the laser receiver and the distance is measured by the first laser rangefinder 302. The correction component 4 is used to correct the distance between the gantry 3 and the two side walls to ensure that the distance between the gantry 3 and the two side walls is the same, so as to reduce the impact of installation errors on the detection accuracy.

[0024] like Figure 5 and Figure 6 As shown, the monitoring component 6 includes a mounting base 601 and a second laser rangefinder 602. A lifting seat 501 is longitudinally slidably mounted on the track climber 5. An electric push rod 502 is fixedly installed inside the track climber 5, and the telescopic end of the electric push rod 502 is fixedly connected to the lifting seat 501. The extension and retraction of the electric push rod 502 drives the lifting seat 501 to rise and fall to prevent interference between the lifting seat 501 and the support frame. The mounting base 601 is fixedly mounted on the lifting seat 501. A hanging shaft 603 is fixedly mounted on the mounting base 601. Multiple levers 604 are rotatably mounted on the hanging shaft 603 at equal intervals. Multiple detection rods 605 are movably inserted into the top of the mounting base 601. A ball head 606 is fixedly installed at one end. Multiple rods 608 are movably inserted into the side of the mounting base 601 corresponding to the position of the lever 604. A reflector 609 is fixedly installed at one end of the rod 608 and a stop plate 610 is fixedly installed at the other end. The lever 604 is Z-shaped, with the shorter section being the input force arm and the longer section being the output force arm. The probe rod 605 is fixedly connected to the input force arm of the lever 604. A return spring 611 is fixedly connected between the stop plate 610 and the mounting base 601. Under the elastic force of the return spring 611, the stop plate 610 is pressed tightly against the output force arm of the lever 604 to amplify the travel of the probe rod 605. The track climber 5 is installed in the slide groove of the gantry 3 and can move along the entire span of the gantry 3. The monitoring component 6 is installed on the track climber 5 via the lifting seat 501. Before scanning and monitoring, the electric actuator 502 is activated to lower the mounting seat 601 and the detection rod 605 on it to a suitable height, so that all the ball joints 606 gently contact the surface of the support frame. When the downhole support deforms, the detection rod 605 will be pressed down and push the reflector 609 to move and approach the second laser rangefinder 602 (which adopts a flat-scan triangular rangefinder laser emitter) through the lever 604. The laser emitted by the second laser rangefinder 602 is reflected by the reflector 609 at different angles, and the laser reception time is different, thereby realizing deformation detection scanning.

[0025] like Figure 7 and Figure 8 As shown, a piston rod 612 is fixedly installed on the abutment plate 610, and a piston 613 is fixedly installed on the other end of the piston rod 612. A dustproof box 614 is fixedly installed on one side of the mounting base 601. A liquid storage tank 615 is fixedly installed on the dustproof box 614, and fluorescent liquid is added to the liquid storage tank 615. Piston cylinders 616 are fixedly inserted into the mounting base 601 at equal intervals. The piston 613 is movably inserted into the piston cylinder 616. The piston cylinder 616 is provided with a liquid inlet and a liquid outlet. The inlet of piston cylinder 616 is fixedly connected to the storage tank 615. The outlet of piston cylinder 616 is fixedly connected to a hose, and a nozzle is fixedly installed at the other end of the hose. A fixing plate 607 for fixing the nozzle is fixedly installed on the probe rod 605. One-way valves are installed on both the inlet and outlet of piston cylinder 616. The one-way valve of the inlet of piston cylinder 616 allows one-way flow to the inside of piston cylinder 616, and the one-way valve of the outlet of piston cylinder 616 allows one-way flow to the outside of piston cylinder 616. The storage tank 615 is filled with fluorescent liquid of a specific color. When a detection rod 605 undergoes significant displacement due to support deformation, the stroke is amplified by the lever 604, pushing the insertion rod 608 and the abutment plate 610 to move. The abutment plate 610 drives the piston rod 612 and piston 613 to move within the piston cylinder 616, pumping the fluorescent liquid out of the storage tank 615. The liquid is then sprayed onto the support surface at the corresponding deformation location via a hose and nozzle, forming a conspicuous marking point. After marking, the piston rod 612 extends using the elastic force of the return spring 611, and the fluorescent liquid is re-drawn from the storage tank 615, facilitating the rapid location of potential hazards by downhole personnel. The installation angle of the nozzle is pre-adjusted to ensure accurate marking.

[0026] The specific working principle is as follows: Initial positioning and calibration. After the equipment is started, the inspection railcar 201 drives the entire equipment to move along the guide rail 1 to the starting position of the roadway to be monitored. The first laser rangefinder 302 emits a laser to a fixed reference point on the top or side wall of the roadway, measures the distance between itself and the reference point, and transmits the data back to the control system. The system calculates whether the current posture of the base 2 and the gantry 3 is parallel to the roadway axis by comparing the data of multiple measuring points. If there is a deviation, the correction component 4 is activated. The correction component 4 works (the working principle has been explained above) to perform fine leveling to ensure that the mounting surface of the gantry 3 is in the ideal theoretical reference position. After automatic inspection and scanning and calibration, the track climber 5 begins to move at a constant speed along the slide on the gantry 3. At the same time, the inspection track car 201 also intermittently drives the entire equipment to move forward along the guide rail 1. The combination of these two sets of movements enables the monitoring component 6 to perform a comprehensive scan of the entire roadway support surface without dead zones. Deformation sensing and signal conversion: During the scanning process, the ball joint 606 at the front end of the probe 605 remains in contact with the support surface. If the support deforms inward or outward, it will push the corresponding probe 605 to produce axial displacement. The displacement of the probe 605 will cause the input arm of the lever 604 to rotate. Since the output arm of the lever 604 is longer, according to the lever 604 principle, this small displacement is amplified and pushes the end of the output arm to produce a more obvious movement. The output arm pushes the abutment plate 610, compresses the return spring 611, and causes the insertion rod 608 and its end reflector 609 to produce synchronous displacement. The second laser rangefinder 602 continuously emits a laser beam to the reflector 609 and receives the reflected signal. The change in the position of the reflector 609 directly changes the laser return distance. The second laser rangefinder 602 will record this distance data in real time and at high frequency. The data processing system compares the received distance signal with the initially calibrated reference value to calculate the real-time deformation of the support at the measuring point. The warning and automatic marking system allows for greater movement of the support plate 610 at measuring points with larger deformations. This causes the piston rod 612 to drive the piston 613 to reciprocate more significantly within the piston cylinder 616. The movement of the piston 613 generates a pumping effect. When it returns, a negative pressure is generated within the piston cylinder 616, drawing the fluorescent liquid from the storage tank 615 into the cylinder through the inlet check valve. During the process, the liquid in the cylinder is pressurized, causing the fluorescent liquid to open the outlet check valve and spray out through the hose from the nozzle, precisely spraying it onto the corresponding deformation point of the support frame behind it, forming a visually significant marker to guide personnel in on-site handling.

[0027] Through the above workflow, the equipment achieves fully automated and efficient monitoring of underground mine support deformation, from macroscopic scanning to microscopic capture, and from precise measurement to intelligent early warning, greatly improving the technical level of mine safety management.
