Description

Technical Field

[0001] This utility model relates to the field of tunnel inspection technology, specifically a mounting bracket for a tunnel lining inspection radar. Background Technology

[0002] In current technological applications, tunnel lining quality inspection supports face a series of challenges, particularly in adapting to the complex and irregular geometry of tunnel interiors. Tunnel linings are typically composed of curved surfaces that are neither parallel nor of standard geometry. This irregularity demands that the inspection supports possess high flexibility and adjustability to ensure effective inspection on these complex surfaces. Currently, radar inspection of shield tunnel lining quality generally employs a field-welded movable workbench, requiring personnel to climb onto the bench, manually lift the instrument, and manually push the bench for inspection. This method results in slow bench movement and low inspection efficiency due to the need for multiple operators; furthermore, because personnel are positioned above the bench during operation, it constitutes high-altitude work, posing significant safety hazards.

[0003] For example, the patent with authorization announcement number CN221373592U describes a robotic arm for radar detection of tunnel lining quality. It consists of a sliding frame, a telescopic cantilever, and a push-pull assembly. It has a simple structure and is easy to install. The entire device can be moved forward and backward by simply pulling the push-pull assembly. The telescopic cantilever can be adjusted in height and angle. It is easy to operate and use, and is easy to promote. However, it needs to be disassembled into individual parts for transportation. When placing it in the tunnel to support and move it, it needs to be lifted manually and its sliding wheels need to be kept in contact with the tunnel wall. If the tunnel entrance is small, the device needs to be raised to a certain position before it can be placed in the tunnel, which reduces the practicality of the device.

[0004] Based on this, a mounting bracket for a tunnel lining detection radar is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0017] 1. This utility model achieves the overall folding function of the device through a folding mechanism, reducing the space occupied by the device and making it convenient for transportation without disassembly. The folding mechanism allows the extended support rod to be folded, reducing the overall space occupied by the device and facilitating its transport.

When the support rod can no longer unfold, the moving wheels on the moving mechanism are adjusted to change their direction of movement, allowing them to move laterally along the tunnel wall. This secures the device to the tunnel wall, facilitating subsequent radar detection of the tunnel. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5 As shown, a tunnel lining detection radar mounting bracket includes a mounting frame 1. A connecting block 11 is fixedly connected to the top of the mounting frame 1. A mounting block 12 is rotatably connected to the top of the connecting block 11. An adjusting frame 13 is rotatably connected to the outer wall of the mounting block 12. A mounting plate is fixedly connected to the end of the adjusting frame 13. A first sleeve 14 is sleeved on the outer wall of the adjusting frame 13. The first sleeve 14 and the adjusting frame 13 are fixed by a limiting bolt. A pull rod 15 is rotatably connected to the outer wall of the first sleeve 14. A support rod 16 is rotatably connected to the bottom of the mounting frame 1. A moving mechanism 2 is provided at the bottom of the support rod 16. A folding mechanism 3 is symmetrically provided at the bottom of the mounting frame 1. A pushing component 4 is provided on the outer wall of the support rod 16.

[0027] In this embodiment, the device can be unfolded by the cooperation of the support rod 16 and the folding mechanism 3, so that it can be supported in the tunnel. The device can be moved in the tunnel by the cooperation of the moving mechanism 2 and the pushing component 4, thereby facilitating the inspection of the tunnel.

[0028] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the moving mechanism 2 includes a fixed rod 21, the top end of which is fixedly connected to the bottom end of a support rod 16. A fixed frame 22 is fixedly connected to the outer wall of the fixed rod 21. A worm gear 23 is rotatably connected to the inner wall of the fixed frame 22. A worm wheel 24 meshes with the outer wall of the worm gear 23. A rotating rod 25 is fixedly connected to the axis of the worm wheel 24. The outer wall of the rotating rod 25 is rotatably connected to the inner wall of the fixed rod 21. A moving wheel 26 is fixedly connected to the bottom end of the rotating rod 25. By rotating the four worm gears 23 in sequence, the worm gears 23 drive the worm wheel 24 to rotate. The worm wheel 24 drives the rotating rod 25 to rotate 90 degrees. The rotating rod 25 drives the moving wheel 26 to rotate synchronously.

[0029] In an optional embodiment, such as Figure 3As shown, a positioning rod 27 is slidably connected to a groove on the fixed rod 21. The positioning rod 27 is inserted into a positioning hole on the rotating rod 25. A first spring 28 is sleeved on the outer wall of the positioning rod 27. One end of the first spring 28 is fixedly connected to the outer wall of the fixed rod 21, and the other end is fixedly connected to the outer wall of the positioning rod 27. During the rotation of the rotating rod 25, the rotating rod 25 pushes the positioning rod 27 to move, which causes the first spring 28 to stretch. When the rotating rod 25 rotates ninety degrees, under the action of the first spring 28, the positioning rod 27 is inserted into the positioning hole on the rotating rod 25 again, thereby completing the positioning and preventing the moving wheel 26 from rotating too much, so that the moving wheel 26 changes from longitudinal to lateral, and the moving wheel 26 can move forward along the tunnel sidewall.

[0030] In an optional embodiment, such as Figure 4 As shown, the folding mechanism 3 includes a second sleeve 31. The bottom of the second sleeve 31 is rotatably connected to the side wall of the support rod 16. An extension rod 32 is slidably connected to a groove on the second sleeve 31. The top of the extension rod 32 is rotatably connected to the bottom end of the connecting block 11. The extension rod 32 is T-shaped. A baffle 37 is fixedly connected to the T-shaped head of the extension rod 32. When the support rod 16 rotates, it drives the second sleeve 31 to move synchronously, so that the extension rod 32 slides in the inner cavity of the second sleeve 31. At the same time, the extension rod 32 drives the baffle 37 to move synchronously.

[0031] In an optional embodiment, such as Figure 4 As shown, a connecting frame 33 is fixedly connected to the outer wall of the second sleeve 31, and an insert rod 34 is slidably connected to the inner cavity of the connecting frame 33. The insert rod 34 passes through the second sleeve 31 and is inserted into a slot on the extension rod 32. The part of the insert rod 34 that is inserted into the slot on the extension rod 32 is trapezoidal. A sliding plate 35 is fixedly connected to the outer wall of the insert rod 34, and the outer wall of the sliding plate 35 is slidably connected to the inner cavity of the connecting frame 33. A second spring 36 is sleeved on the outer wall of the insert rod 34, and one end of the second spring 36 is fixed to the outer wall of the sliding plate 35. The extension rod 32 is connected to the inner cavity of the connecting frame 33. When the extension rod 32 slides in the inner cavity of the second sleeve 31, it squeezes the insertion rod 34 to move. The insertion rod 34 drives the slide plate 35 to move, which compresses the second spring 36. As the support rod 16 rotates continuously, when the extension rod 32 can no longer extend, the insertion rod 34 is inserted into the slot on the extension rod 32 again to prevent the extension rod 32 from retracting into the inner cavity of the second sleeve 31. Under the action of the baffle 37, the extension rod 32 can no longer extend outward.

[0032] In an optional embodiment, such as Figure 5As shown, the pushing component 4 includes a third sleeve 41, with a push rod 42 fixedly connected to the bottom end of the third sleeve 41. A sliding rod 43 is symmetrically slidably connected to the inner cavity of the third sleeve 41. The end of the sliding rod 43 is hinged to the support rod 16 through a pin. During the rotation of the support rod 16, the sliding rod 43 is driven to extend outward synchronously within the inner cavity of the third sleeve 41. Then, by pushing the push rod 42, the entire device can be moved.

[0033] The above embodiment discloses a tunnel lining detection radar mounting bracket. When tunnel lining detection is required, the detection radar is mounted on the mounting plate at the end of the adjusting frame 13. The device is then moved into the tunnel, positioning it near the center. Subsequently, the support rods 16 on both sides rotate in opposite directions, causing the moving wheels 26 to gradually move to the tunnel sidewalls. This adjusts the mounting bracket 1 closer to the tunnel center and lowers its ground clearance, simultaneously lowering the height of the pull rod 15 and the push rod 42 for easier handheld operation. As the support rods 16 rotate, they drive the second sleeve 31 to move synchronously, allowing... The extension rod 32 slides within the inner cavity of the second sleeve 31, causing it to press against the insertion rod 34. The insertion rod 34 then moves the sliding plate 35, compressing the second spring 36. As the support rod 16 rotates continuously, when the extension rod 32 can no longer extend, the insertion rod 34 re-engages with the slot on the extension rod 32, preventing the extension rod 32 from retracting back into the inner cavity of the second sleeve 31. Furthermore, under the action of the baffle 37, the extension rod 32 can no longer extend outwards. At this point, the moving wheel 26 is located on the side wall of the tunnel, and under the constraint of the insertion rod 34 on the second sleeve 31 and the extension rod 32, the height of the moving wheel 26 remains constant without external force. Under normal circumstances (and with operator support required), the operation will not change temporarily. Subsequently, the operator will rotate the four worm gears 23 sequentially (as shown in the diagram). This causes the worm gears 23 to drive the worm wheel 24, which in turn drives the rotating rod 25 to rotate 90 degrees. The rotating rod 25 then drives the moving wheel 26 to rotate synchronously. During this rotation, the rotating rod 25 pushes the positioning rod 27, causing the first spring 28 to stretch. After the rotating rod 25 has rotated 90 degrees, under the action of the first spring 28, the positioning rod 27 re-engages with the positioning hole on the rotating rod 25, thus completing the positioning and preventing the moving wheel 26 from rotating too much, thus changing its position from longitudinal to lateral. The movable wheel 26 can move forward along the tunnel sidewall, and during the rotation of the support rod 16, the sliding rod 43 is driven to extend outward synchronously within the inner cavity of the third sleeve 41. Then, the adjusting frame 13 can be controlled to rotate at multiple angles through the pull rod 15 to change the orientation of the detection radar, making it easier for the detection radar to detect inside the tunnel. By pushing the push rod 42, the entire device can be moved. In summary, through the cooperation of the support rod 16 and the folding mechanism 3, the device can be unfolded and supported inside the tunnel. Through the cooperation of the moving mechanism 2 and the pushing component 4, the device can be moved inside the tunnel, thereby facilitating the detection of the tunnel.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
