[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-10 This invention provides a technical solution: a real-time monitoring device for surface settlement in shallow overburden sections of shield tunnels, comprising a measuring component 1 and an infrared receiver 4 for real-time monitoring of surface settlement in shallow overburden sections of shield tunnels. A retractable component 2 is provided on one outer surface of the measuring component 1 for housing, and a support component 3 is provided on the outer surface of the retractable component 2 for maintaining the stability of the measuring component 1. The measuring component 1 includes a base plate 101 and a first screw 110. A first support frame 102 is fixedly connected to one outer surface of the base plate 101, and a second support frame 103 is rotatably connected to one outer surface of the first support frame 102. A vortex rod 104 is movably embedded between one side of the second support frame 103 and its inner wall, and a fixed shaft 105 is movably embedded between the other side of the second support frame 103 and its inner wall. An infrared measuring instrument body 106 is provided on the outer surface of the fixed shaft 105, and a turbine 107 is fixedly sleeved on the outer surface of the fixed shaft 105. A first tooth 108 is fixedly connected to one outer surface of the second support frame 103, and the outer surface of the vortex rod 104 is close to... A second toothed gear 109 is fixedly sleeved near one end. The outer surface of the worm gear 104 meshes with the outer surface of the turbine 107. A first toothed ring 111 is fixedly sleeved near one end of the outer surface of the first screw 110. A hydraulic rod 112 is provided near the edge of one side of the outer surface of the base plate 101. A movable frame 113 is fixedly connected to one end of the hydraulic rod 112. A toothed ring 114 is rotatably connected to one side of the inner wall of the movable frame 113. A first gear 115 is fixedly sleeved on the outer surface of the toothed ring 114. A second toothed ring 116 is rotatably connected to the inner wall of the other side of the frame 113. A second gear 117 is fixedly sleeved on the outer surface of the second toothed ring 116. A motor 118 is set on one side of the outer surface of the base plate 101 near the edge. An output shaft 119 is fixedly connected to the output end of the motor 118. A gear cylinder 120 is fixedly sleeved on the outer surface of the output shaft 119. The outer surface of the first gear 115 meshes with the outer surface of the gear cylinder 120, and the outer surface of the second gear 117 meshes with the outer surface of the gear cylinder 120.

[0034] In this embodiment, when the real-time surface settlement monitoring device for the shallow overburden section of the shield tunnel is in use, after the shrinkage component 2 is adjusted to the correct position and the support component 3 stably fixes the device on the surface of the monitoring point, the hydraulic rod 112 drives the moving frame 113 to move. The moving frame 113 synchronously drives the toothed ring 114 to move towards the second toothed tooth 109 until the toothed ring 114 meshes with the second toothed tooth 109. At this time, the motor 118 drives the gear cylinder 120 to rotate continuously. Through meshing with the first gear 115, the first gear 115 is driven to rotate. The first gear 115 drives the toothed ring 114 to rotate synchronously. The toothed ring 114 drives the second toothed tooth 109 to rotate. The second toothed tooth 109 drives the fixedly connected worm gear 10. 4. Rotation: The outer surface of the worm gear 104 rotates on the inner wall of the second support frame 103. Simultaneously, the rotation of the worm gear 104 drives the turbine 107 to rotate, which in turn drives the fixed shaft 105 to rotate. The infrared measuring instrument body 106 is fixedly mounted on the outer surface of the fixed shaft 105, thereby adjusting the vertical rotation angle of the infrared measuring instrument body 106. Once the vertical angle of the infrared measuring instrument body 106 reaches the appropriate position, the hydraulic rod 112 is activated again to drive the moving frame 113 to move in the opposite direction. Simultaneously, the moving frame 113 drives the second toothed ring 116 to engage with and then disengage from the first toothed ring 111, thereby driving the toothed ring 114 to move towards the first toothed ring 108 until the toothed ring 114 and the first toothed ring 108 are fully engaged. The toothed ring 114 drives the first toothed tooth 108 to rotate. The rotation of the first toothed tooth 108 drives the second support frame 103 to rotate. The surface of the second support frame 103 rotates along the inner wall of the first support frame 102. Simultaneously, the second support frame 103 drives the fixed shaft 105 to rotate and move. The fixed shaft 105 drives the infrared measuring instrument body 106 to rotate and move. At the same time, the outer surface of the turbine 107 rotates and moves along the outer surface of the worm gear 104 until the rotation angle of the infrared measuring instrument body 106 is appropriate. The infrared measuring instrument body 106 continuously emits a stable infrared signal to the infrared receiver 4. The infrared receiver 4 receives the signal in real time and records the signal propagation distance parameters. When the hydraulic rod 112 drives the moving frame 113 to move... The outer surfaces of the first gear 115 and the second gear 117 are always meshed with the outer surface of the gear cylinder 120. This device, by setting up the measuring component 1, achieves two-directional adjustment through the transmission of the worm gear 107 and the worm shaft 104, and the meshing of the first toothed gear 108 and the second toothed gear 109 with the toothed gear ring 114. First, the motor 118 drives the worm shaft 104 to rotate, which in turn drives the fixed shaft 105 to rotate via the worm gear 107, thereby adjusting the vertical monitoring angle of the infrared measuring instrument body 106 to cover settlement monitoring needs at different heights. Second, the hydraulic rod 112 pushes the moving frame 113, causing the toothed gear ring 114 to mesh with the first toothed gear 108, thereby rotating the second support frame 103 and achieving horizontal angle adjustment of the infrared measuring instrument body 106.This expands the monitoring coverage and avoids blind spots, solving the problem that existing surface settlement monitoring devices, when applied to shallow overburden sections of shield tunnels, suffer from incomplete data collection due to the large variations in surface slope and the dispersed nature of monitoring points, leading to uneven terrain and potential blind spots.

[0035] like Figures 1-10 As shown, a third support frame 121 is fixedly connected to one outer surface of the base plate 101. The inner wall of the third support frame 121 is rotatably connected to the outer surface of the output shaft 119 near one end. The retraction assembly 2 includes a first slide cylinder 201. One end of the first slide cylinder 201 is fixedly connected to the other outer surface of the base plate 101. The outer surface of the first screw 110 is rotatably connected to the inner wall of the first slide cylinder 201. A second slide cylinder 202 is slidably connected to the outer surface of the first slide cylinder 201. The inner wall of the second slide cylinder 202 is fixedly connected to... A first movable cylinder 203 is connected, and the inner wall of the first movable cylinder 203 is threadedly connected to the outer surface of the first screw 110. A second screw 204 is rotatably connected to the outer surface of the first movable cylinder 203, and the inner wall of the second screw 204 is slidably connected to the outer surface of the first screw 110. A third slide cylinder 205 is slidably connected to the outer surface of the second slide cylinder 202, and a second movable cylinder 206 is fixedly connected to the inner wall of the third slide cylinder 205. The inner wall of the second movable cylinder 206 is threadedly connected to the outer surface of the second screw 204.

[0036] In this embodiment, after the support assembly 3 stably fixes the device on the ground surface of the monitoring point, the motor 118 is started. The output end of the motor 118 drives the output shaft 119 to rotate, and the output shaft 119 drives the gear cylinder 120 on the outer surface to rotate synchronously. The gear cylinder 120 meshes with the second gear 117, so the second gear 117 drives the second toothed ring 116 to rotate. At this time, the hydraulic rod 112 is started, and the hydraulic rod 112 pushes the moving frame 113 to move. The moving frame 113 drives the second toothed ring 116 to move until the second toothed ring 116 engages with the second gear 117. When the first toothed insert ring 111 engages, it drives the first screw 110 to rotate. The rotation of the first screw 110 causes the first movable cylinder 203, which is threadedly connected to its outer surface, to move synchronously. Since the inner wall of the first movable cylinder 203 is threadedly fitted with the first screw 110, and the first movable cylinder 203 is fixedly embedded in the inner wall of the second sliding cylinder 202, the first movable cylinder 203 pushes the second sliding cylinder 202 to slide out along the outer surface of the first sliding cylinder 201. At this time, the nesting structure between the first sliding cylinder 201 and the second sliding cylinder 202 gradually... As the first screw 110 continues to rotate, the inner wall of the second screw 204 is slidably connected to the outer surface of the first screw 110, and the second screw 204 is rotatably connected to the outer surface of the first movable cylinder 203. The first screw 110 will drive the second screw 204 to rotate synchronously. When the second screw 204 rotates, the second movable cylinder 206, which is threaded to its outer surface, will move accordingly. The second movable cylinder 206 is fixedly embedded in the inner wall of the third sliding cylinder 205, thereby pushing the third sliding cylinder 205 to slide out along the outer surface of the second sliding cylinder 202, completing the process. The device length can be adjusted in a step-like manner by setting up a shrinking component 2. The first screw 110 and the first moving cylinder 203 are threaded together to push the second sliding cylinder 202 out. Then, the second screw 204 and the second moving cylinder 206 are threaded together to push the third sliding cylinder 205 out a second time, thus realizing the step-like adjustment of the device length. The shrinking component 2 adopts a multi-sliding cylinder nesting and screw drive design, which can realize flexible length extension and retraction. It can not only adapt to monitoring points and infrared receivers 4 with different spacing, but also facilitate storage and transportation, thus improving the practicality and portability of the device.

[0037] like Figures 1-10As shown, the support assembly 3 includes a fixing plate 301. The inner wall of the fixing plate 301 is fixedly connected to the outer surface of the third slide cylinder 205 near one end. Multiple connecting plates 302 are fixedly connected to the outer surface of the fixing plate 301. Each pair of adjacent connecting plates 302 forms a group. A first rotating shaft 303 is movably embedded between the relative inner walls of each group of connecting plates 302. A first rotating plate 304 is fixedly sleeved on the outer surface of each of the multiple first rotating shafts 303. A second rotating plate 304 is fixedly embedded between the relative inner walls of each of the multiple first rotating plates 304. The outer surfaces of the shaft 305 and the multiple second rotating shafts 305 are movably fitted with second rotating plates 306. The outer surface of the third slide cylinder 205 is threaded with a slide rail 307. The inner walls of the multiple second rotating plates 306 are movably fitted with third rotating shafts 310 near one edge. The outer surfaces of the multiple third rotating shafts 310 are fixedly fitted with rotating frames 309 near both ends. The outer surfaces of the multiple rotating frames 309 are fixedly connected with sliders 308 on one side. The outer surfaces of the multiple sliders 308 are slidably connected to the inner walls of the slide rails 307.

[0038] In this embodiment, when the real-time monitoring device for surface settlement in the shallow overburden section of the shield tunnel is in use, the operator needs to first unfold the support component 3 to contact the external ground to provide stable support for the measuring component 1 and the contraction component 2. First, rotate the slide rail 307. The inner wall of the slide rail 307 will slide along the outer surface of the third slide cylinder 205. Simultaneously, as the slide rail 307 moves spirally, the outer surface of the slider 308 will slide along the inner wall of the slide rail 307. The sliding of the slide rail 307 drives the slider 308 to move, which in turn drives the rotating frame 309 to move. The rotating frame 309 drives the third rotating shaft 310 to move, which in turn pulls the second rotating plate 306. One side of the inner wall of the second rotating plate 306 will rotate along the outer surface of the third rotating shaft 310. The other side of the second rotating plate 306... The inner side wall rotates around the second rotating shaft 305, which in turn drives the inner side wall of the first rotating plate 304 to rotate and unfold the first rotating shaft 303 until multiple first rotating plates 304 form a triangular support structure with the ground and between the first rotating plate 304 and the second rotating plate 306, thus stabilizing the device on the ground surface of the monitoring point. This device is equipped with a support component 3. When the support component 3 needs to be unfolded, the rotating slide rail 307 can drive the slider 308 and the rotating frame 309 to work together, so that the first rotating plate 304 and the second rotating plate 306 form a triangular support structure. Multiple connecting plates 302 cooperate with the first rotating shaft 303, the second rotating shaft 305 and the third rotating shaft 310 to flexibly adjust the support angle and adapt to the ground surface with different slopes and flatness, further improving the stability and reliability of the device in complex environments.

[0039] The usage and working principle of this device: When using the real-time surface settlement monitoring device for shallow overburden sections of shield tunnels, the operator first needs to unfold the support component 3 to make contact with the external ground to provide stable support for the measuring component 1 and the contraction component 2. First, rotate the slide rail 307. The inner wall of the slide rail 307 will slide along the outer surface of the third slide cylinder 205. Simultaneously, as the slide rail 307 moves spirally, the outer surface of the slider 308 will slide along the inner wall of the slide rail 307. The sliding of the slide rail 307 drives the slider 308 to move, which in turn drives the rotating frame 309 to move. The rotating frame 309... Moving the third rotating shaft 310 pulls the second rotating plate 306, causing one inner wall of the second rotating plate 306 to rotate along the outer surface of the third rotating shaft 310. The other inner wall of the second rotating plate 306 rotates around the second rotating shaft 305. Simultaneously, this causes one inner wall of the first rotating plate 304 to rotate and unfold the first rotating shaft 303, until multiple first rotating plates 304 form a triangular support structure with the ground and between the first rotating plates 304 and the second rotating plates 306, stabilizing the device on the monitoring point surface. At this point, the motor 118 is started, and the output end of the motor 118 drives the output shaft 119. The output shaft 119 rotates, causing the gear cylinder 120 on its outer surface to rotate synchronously. The gear cylinder 120 meshes with the second gear 117, which in turn drives the second toothed ring 116 to rotate. At this time, the hydraulic rod 112 is activated, which pushes the moving frame 113 to move. The moving frame 113 drives the second toothed ring 116 to move until the second toothed ring 116 meshes with the first toothed ring 111. At this time, the first toothed ring 111 drives the first screw 110 to rotate. When the first screw 110 rotates, it drives the first moving cylinder 203, which is threaded on its outer surface, to move synchronously. The inner wall of a movable cylinder 203 is threadedly engaged with the first screw 110, and the first movable cylinder 203 is fixedly embedded in the inner wall of the second sliding cylinder 202. The first movable cylinder 203 will push the second sliding cylinder 202 to slide out along the outer surface of the first sliding cylinder 201. At this time, the nesting structure between the first sliding cylinder 201 and the second sliding cylinder 202 gradually unfolds. As the first screw 110 continues to rotate, because the inner wall of the second screw 204 is slidably connected to the outer surface of the first screw 110, and the second screw 204 is rotatably connected to the outer surface of the first movable cylinder 203, the first screw 110 will drive the second screw 204 to rotate synchronously.When the second screw 204 rotates, the second movable cylinder 206, which is threaded to its outer surface, moves accordingly. The second movable cylinder 206 is fixedly embedded in the inner wall of the third sliding cylinder 205, thereby pushing the third sliding cylinder 205 to slide out along the outer surface of the second sliding cylinder 202, completing the secondary adjustment of the device length until the entire shrink assembly 2 extends to the appropriate distance between the monitoring point and the infrared receiver 4. After the shrink assembly 2 is adjusted to the correct position, the control hydraulic rod 112 continues to drive the movable frame 113 to move. The movable frame 113 simultaneously drives the second toothed ring 116 to disengage from the first toothed ring 111, and drives the toothed ring 114 to move towards the direction of the second toothed tooth 109 until the toothed ring 109 is engaged. The toothed ring 114 meshes with the second toothed gear 109. At this time, the gear cylinder 120 rotates continuously, driving the first gear 115 to rotate through meshing with it. The first gear 115 drives the toothed ring 114 to rotate synchronously, which in turn drives the second toothed gear 109 to rotate. The second toothed gear 109 then drives the fixedly connected worm gear 104 to rotate. The outer surface of the worm gear 104 rotates on the inner wall of the second support frame 103. Simultaneously, the rotation of the worm gear 104 drives the turbine 107 to rotate, which in turn drives the fixed shaft 105 to rotate. The infrared measuring instrument body 106 is fixedly mounted on the outer surface of the fixed shaft 105, thereby driving... The infrared measuring instrument body 106 is rotated up and down to adjust its angle. After the angle of the infrared measuring instrument body 106 is moved to a suitable position, the hydraulic rod 112 is activated to drive the moving frame 113 to move in the opposite direction. The moving frame 113 simultaneously drives the second toothed ring 116 to engage with the first toothed ring 111 and then disengage, thereby driving the toothed ring 114 to move towards the first toothed ring 108 until the toothed ring 114 and the first toothed ring 108 are fully engaged. The toothed ring 114 will drive the first toothed ring 108 to rotate. When the first toothed ring 108 rotates, it will drive the second support frame 103 to rotate. The surface of the second support frame 103 will move along the first support frame. The inner wall of 102 rotates, and simultaneously the second support frame 103 drives the fixed shaft 105 to rotate and move. The fixed shaft 105 drives the infrared measuring instrument body 106 to rotate and move. At the same time, the outer surface of the turbine 107 rotates and moves along the outer surface of the worm gear 104 until the rotation angle of the infrared measuring instrument body 106 is appropriate. The infrared measuring instrument body 106 continuously emits a stable infrared signal to the infrared receiver 4. The infrared receiver 4 receives the signal in real time and records the signal propagation distance parameters. When the hydraulic rod 112 drives the moving frame 113 to move, the outer surfaces of the first gear 115 and the second gear 117 are always meshed with the outer surface of the gear cylinder 120.

Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the infrared measuring instrument body 106, hydraulic rod 112, motor 118 and infrared receiver 4 will not be explained in detail.
