Description

Technical Field

[0001] The present invention relates to the technical field of tunnel structure detection, and in particular to a tunnel structure detection device. Background Art

[0002] Tunnel structure inspection is a key link in ensuring the safe operation of transportation infrastructure. Its core lies in evaluating the integrity, stability and durability of tunnel structures through multidisciplinary technical means. Tunnels are also engineering buildings. As the age of tunnels increases, major lining defects such as deformation and voids may appear on the tunnel lining surface, which will correspondingly reduce the overall bearing capacity of the lining structure and threaten the safety of vehicles and pedestrians on the roads in the tunnel. It is necessary to conduct regular health inspections of the tunnel lining structure to timely understand the type, location and scale of potential defects in the lining structure and provide a basis for early maintenance.

[0003] In the field of tunnel engineering maintenance, traditional wall inspection methods mainly rely on manual visual inspection or simple contact tools, which have many limitations. On the one hand, manual inspection is easily influenced by subjective experience, making it difficult to accurately quantify hidden dangers such as wall deformation and peeling, and there are safety risks when operating at high altitude or in narrow environments. On the other hand, existing automated inspection equipment mostly uses direct adhesion to the wall for inspection. During operation, it is necessary to carefully avoid sharp parts of the wall, and the inspection needs to be frequently interrupted to adjust the equipment position, which further limits the inspection speed. In addition, since geological radar, area array cameras and other inspection equipment are relatively expensive, they need to be used with caution during the inspection process, which also leads to relatively low inspection efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that existing automated detection equipment is relatively expensive, requires great caution during use to avoid damage, reduces the detection speed, and leads to relatively low detection efficiency. A tunnel structure detection device is proposed to solve the problem that existing automated detection equipment is relatively expensive, requires great caution during use to avoid damage, reduces the detection speed, and leads to relatively low detection efficiency.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Preferably, the reciprocating assembly includes an arc-shaped slide rail, and the arc-shaped slide rails are fixedly installed on the left and right sides of the interior of the frame body. Arc-shaped sliders are slidably installed on the two arc-shaped slide rails, and drive motors are fixedly installed on the two arc-shaped sliders.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0016] In the embodiment, Figure 1-3 A tunnel structure detection device is provided, comprising a body 1, a hydraulic mechanical arm 2 is rotatably mounted on the top of the body 1, a frame 3 is rotatably mounted on the other end of the hydraulic mechanical arm 2, a reciprocating component 4 is opened inside the frame 3, a mounting frame 5 is provided on the reciprocating component 4, the interior of the mounting frame 5 is slidably connected to the mounting part 7 through a reset component 6, a displacement detection component 8 is provided at the bottom of the mounting part 7, and the top of the mounting part 7 is connected to the roller 10 through a rebound component 9.

[0017] Reference Figure 2-3 , wherein the reciprocating assembly 4 includes an arc-shaped slide rail 41, and the arc-shaped slide rails 41 are fixedly installed on the left and right sides of the interior of the frame 3, and the two arc-shaped slide rails 41 are slidably installed with arc-shaped sliders 42, and the two arc-shaped sliders 41 are fixedly installed with drive motors 43, and the two arc-shaped sliders 42 are fixedly connected to the mounting frame 5; Through the above-mentioned structural setting, when the hydraulic mechanical arm 2 drives the frame 3 to move along the tunnel wall for detection, when passing a problematic position, the movement of the frame 3 is stopped, and then the drive motor 43 is started. The drive motor 43 drives the arc-shaped slider 42 to drive the mounting frame 5 to move back and forth along the arc-shaped slide rail 41, and the abnormal situation at this position is detected by the roller 10.

[0018] Reference Figure 2-3, wherein the reset assembly 6 includes a limit groove 61, the limit groove 61 is provided inside the mounting frame 5, a limit block 62 adapted to the limit groove 61 is fixedly mounted on the mounting member 7, and the limit block 62 is slidably connected to the limit groove 61 through a reset spring 63; Through the above-mentioned structural setting, during the detection process, the deformation of the tunnel wall will cause a bulge to appear there. When the roller 10 encounters the bulge deformation of the wall, the bulge wall when the roller 10 moves will press the roller 10 downward. When pressing down, the mounting part 7 moves in the limiting groove 61 through the limiting block 62, and at the same time squeezes the reset spring 63 downward. After the roller 10 moves over the wall bulge, the pressure is reduced and the reset spring 63 pushes the limiting block 62 to reset through elasticity, waiting for the subsequent deformation bulge to appear.

[0019] Reference Figure 1-3 The displacement detection assembly 8 includes a pressure roller 81, which is fixedly mounted on the bottom of the mounting member 7. A plurality of positioning slots 84 are provided on both sides of the interior of the frame 3. The interiors of the two positioning slots 84 are slidably connected to the detection plate 82. A second spring 85 located inside the positioning slot 84 is fixedly mounted on the bottom of the detection plate 82. A displacement sensor 83 is fixedly mounted on the bottom of each of the detection plates 82. Through the above-mentioned structural setting, when the roller 10 passes through the raised position and presses the mounting part 7 downward, the mounting part 7 drives the pressure roller 81 to press downward synchronously. When the mounting part 7 drives the roller 10 to move, the downward pressure roller 81 gradually moves toward the detection plate 82 on the moving route. According to the pressing depth of the roller 10, the pressure roller 81 presses down the detection plate 82 synchronously. The positioning groove 84 can limit the moving position of the detection plate 82 when it moves, ensuring the moving direction of the detection plate 82 and its own stability. When the detection plate 82 is pressed downward, the displacement sensor 83 detects a signal and sends the displacement data of different detection plates 82 when they are pressed downward to the control panel 11. The second spring 85 can reset the detection plate 82 through elasticity after the pressure roller 81 leaves the detection plate 82.

[0020] Reference Figure 1-3 The rebound assembly 9 includes a mounting groove 91. The mounting grooves 91 are symmetrically opened inside the mounting member 7. Third springs 92 are fixedly installed inside the two mounting grooves 91. Mounting blocks 93 that match the mounting grooves 91 are fixedly installed on both sides of the roller 10. The mounting blocks 93 are connected to the third springs 92. A pressure sensor 94 is fixedly installed at the bottom of the roller 10. Through the above-mentioned structural setting, when the roller 10 is on the normal wall, the third spring 92 is always kept in a compressed state. If there is a pit on the tunnel wall due to the shedding of the outer layer of the wall, when the roller 10 moves to the pit, the wall releases the pressure on the roller 10, causing the third spring 92 to reset, driving the bottom mounting block 93 to move upward along the mounting groove 91, so that the roller 10 rises and moves into the inside of the pit, while reducing the squeeze on the pressure sensor 94. After detecting a large change in pressure, the pressure sensor 94 transmits the signal to the control panel 11 for data recording.

[0021] Reference Figure 1-3 , wherein a control panel 11 is provided on the body 1, and the control panel 11 is electrically connected to other components respectively; With the above-mentioned structural arrangement, when the detection device is working, the device operation is controlled by the control panel 11 to receive data transmitted back by the displacement sensor 83 and the pressure sensor 94 .

[0022] Working principle: Implementation steps for the first innovation point: Step 1: When preparing to inspect the tunnel, the hydraulic mechanical arm 2 is operated through the control panel 11 to drive the frame 3 close to the tunnel wall, and then the roller 10 is brought into contact with the wall and simultaneously driven to move forward at a uniform speed along the wall. When the roller 10 passes a position with a protrusion or a depression, the movement of the frame 3 is stopped, and then the drive motor 43 is started. The drive motor 43 drives the arc-shaped slider 42 to drive the mounting frame 5 to move back and forth along the arc-shaped slide rail 41. The roller 10 detects abnormal conditions at the position, and the collected data is transmitted to the control panel 11. Step 2: When the roller 10 passes the raised position and presses the mounting member 7 downward, the mounting member 7 drives the pressure roller 81 to press downward synchronously. As the mounting member 7 drives the roller 10 to move, the downward pressure roller 81 gradually presses the detection plate 82 on the moving path. According to the pressing depth of the roller 10, the pressure roller 81 presses the detection plate 82 synchronously. When the detection plate 82 is pressed downward, the displacement sensor 83 detects a signal and sends the displacement data of different detection plates 82 when pressed downward to the control panel 11. Step 3: When the roller 10 moves to the pit, the wall releases the pressure on the roller 10, causing the third spring 92 to reset, driving the bottom mounting block 93 to move upward along the mounting groove 91, causing the roller 10 to rise and move into the pit, while reducing the squeeze on the pressure sensor 94. After detecting a large change in pressure, the pressure sensor 94 transmits the signal to the control panel 11 for data recording.
