Description

Technical Field

[0001] This invention relates to the field of laser ranging technology, specifically a laser ranging device for monitoring tunnel structural deformation. Background Technology

[0002] A tunnel is a closed passage built in a mountain, underground, or underwater to allow vehicles, pedestrians, trains, or pipelines to pass through. Tunnel structural deformation refers to the changes in shape, size, or position of the tunnel lining and surrounding rock and soil during construction and operation that exceed the safe range allowed by the design. Deformation is the result of an imbalance between load and structural resistance. The main types of deformation include convergence deformation, crown settlement, floor heave, lining cracking, circumferential joints, longitudinal joints, lining spalling, joint misalignment, and overall displacement.

[0003] The patent application with application number CN202321437720.5 mentions a "laser rangefinder". This patent can directly observe the relative position of the photosensitive surface of the photosensitive element and the focal point of the receiving lens group, which facilitates the alignment of the two and improves the stability, accuracy and efficiency of the debugging results.

[0004] However, when using lasers to monitor tunnel deformation, existing technologies often encounter problems during long-term monitoring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a group testing and correction component, the support motor, support positioning frame, and reverse motor drive the support fixing frame, laser reflector, and laser receiver to rotate and adjust their angles. The monitoring reflection position is adjusted according to the tunnel's shape, size, and monitoring environment, so that the laser is received and reflected at a set angle. The card protrusion limit frame and top support limit frame are moved by the double-moving electric slide rail and the same-distribution electric slide rail. The traction electric push rod, traction processing rope, swing universal joint, and central support electric push rod drive the swing universal joint and load-bearing swing plate to swing and rise and fall. This allows for rapid adjustment and correction of the equipment according to the actual required test height and position, enabling different position testing processing of the laser emitter and laser rangefinder, and improving the accuracy of test alignment. By adjusting the rotation cylinder, the fixed sleeve, and the swing motor to rotate and reposition the laser emitter, the position of the laser emitted by the laser emitter is adjusted. In conjunction with the linkage motor, the swing operating frame, the hydraulic motor, and the linkage operating frame, the position of the laser receiver is switched. By switching the laser emission and reception at multiple positions and angles, and with the fixed-angle reflection processing and position offset reception processing of the laser reflector, different numbers of laser emitters and laser reflectors can be used for combined testing. The rotating processing cylinder drives the laser scanner to perform three-dimensional scanning of the parts with large data deviations. By cooperating with multiple sets of moving laser emitters and fixed laser reflectors, a single device can be used for continuous monitoring, reducing the occurrence of excessive data deviations caused by equipment offset and greatly improving the accuracy of monitoring and processing. By coordinating multi-position fixed-angle reflection and transmission positions, multi-position alignment laser testing and offset monitoring are achieved. Combined with laser reflection monitoring and three-dimensional positioning scanning, different laser monitoring methods are used to accurately monitor the actual deformation of the tunnel's internal structure. This effectively solves the problem in existing technologies where the transmitting and receiving equipment simultaneously follow the tunnel's deformation, resulting in tunnel deformation but unchanged monitoring data. It also reduces the offset and influence of the monitoring environment on the laser, improves the accuracy of monitoring data, reduces data deviation or insufficiency, and enhances the accuracy and stability of monitoring.

[0016] 2. Equipped with a cleaning component, the system utilizes a lifting electric actuator to drive the lifting fixing block, a shifting pneumatic actuator to drive the shifting alignment frame, and a linkage motor to drive the linkage processing block. Through multi-position rotation switching and lifting movement, the absorbent brush is attached to the surfaces of the laser reflector and laser receiver according to their position and angle. A lifting electric slide rail drives the lifting alignment block, and a hydraulic actuator drives the double-cutting fixing block to ensure the absorbent brush is attached to the surfaces of the swing universal frame, laser emitter, swing operating frame, and laser receiver. Multi-position rotation switching allows for precise cleaning of the testing equipment. The position of the components is adjusted, and when the equipment is subject to positional or angular displacement, the cleaning position can be quickly corrected. Liquid is injected into the side of the brushing cylinder and absorbent brush through the liquid pump, water pumping fixed pipe and liquid storage tank. In conjunction with the brushing motor and brushing electric push rod, the brushing cylinder and absorbent brush are rotated to brush and clean the surfaces of the swing universal frame, laser emitter, swing operating frame and laser receiver. This achieves rapid cleaning of the equipment and avoids the impact of dust and oil film brought up by vehicles on the equipment surface due to long-term use, thus improving the stability of equipment operation.

[0017] In summary, by coordinating the testing and repair components and the cleaning components, by simultaneously coordinating equipment monitoring and cleaning, and by coordinating multi-reflection mobile laser monitoring and three-dimensional laser scanning monitoring, we can achieve long-term continuous monitoring and processing of tunnel structural deformation, reduce data deviation and data interference, and ensure the accuracy of the monitoring data.

[0023] The working principle and usage process of this invention are as follows: When monitoring the deformation of the tunnel structure, the operator inserts the combined screw 223 into the wall attachment inside the tunnel body 1, then slips the soft pressure treatment pad 225 onto the side end of the combined screw 223, and slips the combined fixing bracket 224 onto the side end of the combined screw 223. Another soft pressure treatment pad 225 is then slipped onto the side ends of the combined screw 223 and the combined fixing bracket 224. The combined nut 226 is rotated, pushing and pressing the combined fixing bracket 224 and the soft pressure treatment pad 225 together, causing the soft pressure treatment pad 225 to press against the wall of the tunnel body 1, thereby fixing and securing the combined fixing bracket 224. The support frame 234 is installed on the wall inside the tunnel as required. At this time, the corner-cutting screw 228 rotates along the processing screw block 227, which drives the corner-cutting processing block 229 to move. The corner-cutting processing block 229 pushes the swing support block 230 to rotate and switch along the side of the combined fixed bracket 224, thereby adjusting the angle of the swing support block 230. Then, the support motor 231 drives the support positioning bracket 232 to rotate along the swing support block 230, and the counter-motor 233 drives the support frame 234 to rotate along the support positioning bracket 232, adjusting the angle of the laser reflector 235 and the laser receiver 236, and adjusting the laser monitoring position according to the shape and size of the tunnel. After installation, the locking rod 206 is fitted between the locking bracket 203 and the top support bracket 204, and the locking rod 206, locking bracket 203 and top support bracket 204 are fitted and connected by the locking pin 205. The locking bracket 203 and top support bracket 204 are moved by the double electric sliding rail 201 and the same electric sliding rail 202, thereby moving the swing universal frame 211 and the load-bearing swing plate 218 simultaneously. The pulling electric push rod 207 drives the pulling rope 208 to move up and down. At this time, the swing universal frame 211 and the load-bearing swing plate 218 are limited by the swing universal joint 210, and the swing universal joint 210 moves synchronously with the pulling electric push rod 207 through the middle support electric push rod 209, so as to achieve the alignment correction and ensure the optimal angle and support position of the swing universal frame 211 when in use. Air is injected into the correction rotating cylinder 212 through an external air supply component. The air intake drives the correction rotating cylinder 212 to rotate the correction fixing sleeve 213 along the swing universal frame 211. The swing motor 214 drives the laser emitter 215 to rotate along the swing universal frame 211 and the correction fixing sleeve 213, adjusting the angle and position of the laser emitter 215. At the same time, the linkage motor 220 drives the swing operating frame 219 to rotate along the linkage operating frame 221. Hydraulic oil is injected into the hydraulic motor 222 through a hydraulic component. The hydraulic oil drives the rotating structure in the hydraulic motor 222 to drive the linkage operating frame 221 to rotate along the swing operating frame 219 and the load-bearing swing plate 218, thereby adjusting the position of the swing operating frame 219 and the laser receiver 236 according to the position of laser reflection. After the position adjustment is completed, a laser is emitted by the laser emitter 215. After the laser is emitted, it comes into contact with the laser reflector 235 and is reflected by the laser reflector 235 to the laser receiver 236 located at the position of the load-bearing swing plate 218. Through continuous position switching and simultaneous laser monitoring at multiple positions, a single laser emitter 215 and a continuously switching single laser reflector 235 are used for a single independent side end, while multiple sets of laser emitters 215 and multiple sets of continuously switching laser reflectors 235 are used for multiple sets of joint correction and alignment processing. Air is injected into the rotating processing cylinder 216 through an external air supply component. The air intake drives the rotating processing cylinder 216 to drive the laser scanner 217 to perform three-dimensional scanning on the part with large data deviation. Through the coordinated operation of laser reflection monitoring and three-dimensional positioning scanning, the actual deformation of the tunnel's internal structure can be accurately monitored using laser, thereby improving the safety of tunnel use. The lifting electric actuator 305 drives the lifting fixed block 306 to rise. Air is injected into the rotary processing cylinder 216 by an external air supply component. The air intake drives the shifting pneumatic actuator 307 to drive the shifting alignment frame 308 to rotate along the lifting fixed block 306. The coupling motor 309 drives the coupling processing block 310 and the second set of lifting electric actuators 305 to rotate and switch. The lifting electric actuator 305, the shifting pneumatic actuator 307 and the coupling motor 309 drive the shifting alignment frame 308, the coupling processing block 310 and the lifting fixed block 306 to continuously rise. The descent and rotation are used to achieve accurate alignment. The absorbent brush 320 is attached to the surface of the laser reflector 235 and the laser receiver 236. The lifting alignment block 313 is moved up and down by the lifting electric slide rail 312. Hydraulic oil is injected into the hydraulic actuator 315 in conjunction with the hydraulic components. The hydraulic oil drives the rotating structure in the hydraulic actuator 315 to push the double-cut fixing block 316 to rotate along the brushing electric push rod 314, so that the absorbent brush 320 is attached to the surface of the swing universal frame 211, the laser emitter 215, the swing operating frame 219 and the laser receiver 236. After alignment and bonding are completed, the liquid pump 323 and the water pumping fixed pipe 321 draw cleaning fluid from the inside of the liquid storage tank 322. The cleaning fluid enters the brushing fixed cylinder 319 through the water pumping fixed pipe 321, and then penetrates into the inside of the absorbent brush cloth 320. The brushing motor 311 drives the brushing fixed cylinder 319 and the absorbent brush cloth 320 to rotate, using the absorbent brush cloth 320 to clean the surfaces of the laser reflector 235 and the laser receiver 236. Then, the cleaning electric slide rail 301 moves the cleaning top support plate 302, and the bonding electric slide rail 303 moves the bonding sliding plate 3. 04. Movement enables continuous movement and switching of alignment, improving the stability of brushing and cleaning alignment. The brushing electric push rod 314 drives the double-cutting fixed block 316 and the fine-tuning rod 318 to move up and down, causing the brushing fixed cylinder 319 to rotate along the fine-tuning rod 318. This allows the absorbent brush cloth 320 to brush and clean the surfaces of the swing universal frame 211, laser emitter 215, swing operating frame 219, and laser receiver 236, achieving rapid cleaning of the equipment and avoiding the impact of dust and oil film brought up by vehicles on the equipment surface due to long-term use, thus improving the stability of equipment operation.
