Description

Technical Field

[0001] The present invention relates to the technical field of tunnel radar scanning, and particularly to a tunnel radar scanning adaptive bracket. Background Art

[0002] As an important transportation infrastructure, the safety and stability of a tunnel are of crucial importance. As the main load-bearing part of the tunnel, the lining structure directly affects the overall performance of the tunnel. However, during the construction and operation of the tunnel, the lining structure often has defects such as cracks and cavities due to factors such as geological conditions and construction techniques. If these defects are not discovered and repaired in time, the safety of the tunnel will be seriously threatened.

[0003] However, the traditional method for detecting the tunnel lining structure mainly relies on manually holding a radar antenna for scanning. This method has many deficiencies. First, workers need to hold the radar antenna up for a long time, resulting in high labor intensity and being prone to operation errors due to fatigue. Second, the environment inside the tunnel is complex and the space is narrow, and it is difficult to ensure the close fit between the hand-held scanner and the lining surface, thus affecting the scanning effect. In addition, the hand-held scanning method is inefficient and difficult to meet the needs of large-scale tunnel detection. Summary of the Invention

[0024] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0025] Please refer to Figures 1 to 9, the present invention provides a tunnel radar scanning adaptive bracket, including a support cover 1, a lifting mechanism, and a pushing platform 2. The lifting mechanism includes a lifting column 3, a lifting screw 4, a mounting box 5, and a fixed cylinder 6. Above the lifting column 3, two hydraulic rods 7 are hingedly arranged. Inside the lifting column 3, there is a threaded groove 8. One end of the lifting screw 4 is provided with a driven gear 9. Inside the mounting box 5, a driving gear 10 is rotatably arranged. The driving gear 10 is rotated by a handwheel 11, and the diameter of the driven gear 9 is larger than the diameter of the driving gear 10. Below the pushing platform 2, a plurality of universal wheels 12 are provided. The support cover 1 is hinged to the corresponding hydraulic rod 7 and is located at the output ends of the two hydraulic rods 7. The lifting column 3 is slidably connected to the fixed cylinder 6 and is located inside the fixed cylinder 6. The lifting screw 4 is threadedly connected to the lifting column 3 and is located inside the threaded groove 8. The lifting screw 4 is rotatably connected to the fixed cylinder 6 through a bearing and is located inside the fixed cylinder 6. The mounting box 5 is fixedly connected to the pushing platform 2 and is located below the pushing platform 2, and the driving gear 10 meshes with the driven gear 9. The fixed cylinder 6 is arranged in the middle of the pushing platform 2.

[0026] In this embodiment, by rotating the driving gear 10 through the handwheel 11, using the meshing of the driving gear 10 and the driven gear 9, and the diameter of the driven gear 9 being larger than the diameter of the driving gear 10, it realizes driving the lifting screw 4 to rotate labor - savingly, and then drives the lifting column 3 to slide inside the fixed cylinder 6, thereby adjusting the height of the support cover 1 to adapt to the requirements of different scanning positions. The hydraulic rods 7 are hingedly arranged, which can flexibly change the angle of the support cover 1 and improve the flexibility of scanning. The universal wheels 12 are arranged below the pushing platform 2, which is convenient for the overall movement of the bracket and improves the convenience of equipment use, enabling quick conversion between different detection positions. The overall structure can achieve stable support and flexible adjustment of the radar antenna, which helps to improve the efficiency and accuracy of tunnel radar scanning.

[0027] Furthermore, the lifting mechanism further includes two limiting members. The limiting members include a limiting rod 13 and a limiting cylinder 14. The limiting rod 13 is slidably connected to the limiting cylinder 14 and is located inside the limiting cylinder 14. The limiting rod 13 is also hinged to the support cover 1 and is located below the support cover 1. The limiting cylinder 14 is hinged to the lifting column 3 and is located above the lifting column 3 and also between the two hydraulic rods 7.

[0028] In this embodiment, through this design, the position of the support cover 1 during the lifting process is restricted, preventing the support cover 1 from shaking or shifting during lifting, ensuring the stability of the support cover 1, and further ensuring the position accuracy of the radar antenna during the scanning process, improving the accuracy and reliability of the scanning data, and helping to obtain a clearer image of the tunnel lining structure.

[0029] Further, a plurality of limiting strip-shaped grooves 15 are provided on the outer side of the lifting column 3, a plurality of limiting strip bodies 16 are provided on the inner side of the fixed cylinder 6, and the plurality of limiting strip bodies 16 are located in the corresponding limiting strip-shaped grooves 15.

[0030] In this embodiment, the limiting strip body 16 slides in the limiting strip-shaped groove 15 to play a guiding and limiting role, preventing the lifting column 3 from rotating or shifting in the fixed cylinder 6, ensuring the smooth operation of the lifting mechanism, improving the reliability and stability of the entire bracket, and ensuring the smooth progress of the radar scanning work.

[0031] Further, the tunnel radar scanning adaptive bracket further includes a plurality of guiding mechanisms, two clamping mechanisms and two supporting mechanisms. The plurality of guiding mechanisms are symmetrically arranged in pairs at both ends of the support cover 1, the two clamping mechanisms are symmetrically arranged on both sides of the support cover 1, and the two supporting mechanisms are symmetrically arranged on both sides of the pushing platform 2.

[0032] In this embodiment, through this symmetrical layout, the bracket is more stable in structure and the force is more evenly distributed. The guiding mechanism can guide the direction of the bracket during movement and scanning to ensure the accuracy of the scanning path; the clamping mechanism can clamp and fix radar antennas or other devices of different sizes, improving the versatility and applicability of the device; the supporting mechanism can assist in supporting and adjusting the height and posture of the bracket, further enhancing the stability and flexibility of the bracket, so that the bracket can better adapt to different tunnel environments and scanning requirements.

[0033] Further, the guiding mechanism includes a guiding wheel 17, a guiding seat 18 and a support 19. A guiding rod 20 is provided below the guiding seat 18. One end of the guiding rod 20 is provided with a bottom plate 21. A spring 22 is fixedly arranged on the bottom plate 21, and the spring 22 is sleeved on the guiding rod 20. A guiding groove 23 is provided in the support 19. A pressure sensor 24 is provided below the support 19. The guiding wheel 17 is rotatably arranged on the guiding seat 18. The guiding seat 18 is slidably connected to the support 19 and is located in the guiding groove 23. The guiding rod 20 penetrates through the inner bottom of the guiding groove 23. The spring 22 is also fixedly connected to the support 19 and is located below the support 19. And the bottom plate 21 is located directly above the pressure sensor 24. The support 19 is fixedly connected to the support cover 1 and is located at one end of the support cover 1.

[0034] In this embodiment, during the movement of the bracket, the guiding wheel 17 can roll to reduce friction. The guiding seat 18 slides in the guiding groove 23 to ensure the accuracy of the moving direction. The spring 22 can play a buffering role. When encountering an uneven lining concrete surface or an obstacle, it can reduce the vibration of the bracket and protect devices such as radar antennas. The pressure sensor 24 can monitor the pressure between the radar antenna and the lining concrete surface in real time, provide feedback information for the operator, facilitate timely adjustment of the bracket posture and moving speed, and improve the safety and accuracy of the scanning operation.

[0035] Further, the clamping mechanism includes a clamping plate 25, a clamping thread sleeve 26 and a clamping screw 27. The clamping plate 25 is fixedly connected to the clamping screw 27 and is located at one end of the clamping screw 27. The clamping thread sleeve 26 is rotatably connected to the support cover 1 through a bearing and is located on one side of the support cover 1. The clamping thread sleeve 26 is also threadedly connected to the clamping screw 27 and is sleeved on the clamping screw 27. And one end of the clamping screw 27 extends into the support cover 1.

[0036] In this embodiment, when the clamping thread sleeve 26 is rotated, it can drive the clamping screw 27 to move, so that the clamping plate 25 approaches or moves away, realizing the clamping and fixing of devices of different sizes. This design is simple and convenient to operate, firmly clamped and reliable, can adapt to different specifications of radar antennas or other detection devices, improves the versatility and practicality of the bracket, and ensures that the device will not loosen or fall during the scanning process.

[0037] Furthermore, the propping mechanism includes a propping plate 28, a propping threaded sleeve 29, and a propping screw rod 30. A positioning rod 31 is disposed above the propping plate 28. The propping plate 28 is fixedly connected to the propping screw rod 30 and is located at one end of the propping screw rod 30. The propping threaded sleeve 29 is rotatably connected to the pushing platform 2 through a bearing and is located on one side of the pushing platform 2. The propping threaded sleeve 29 is also threadedly connected to the propping screw rod 30 and is sleeved on the propping screw rod 30. One end of the propping screw rod 30 extends below the pushing platform 2. The positioning rod 31 penetrates through the pushing platform 2.

[0038] In this embodiment, by rotating the propping threaded sleeve 29, the propping screw rod 30 can be driven to move, thereby adjusting the height of the propping plate 28, achieving auxiliary support and adjustment of the height of the bracket. The setting of the positioning rod 31 can ensure the stability of the propping plate 28 and prevent the propping plate 28 from shaking or shifting during the propping process. The propping mechanism can further enhance the stability and flexibility of the bracket, enabling the bracket to better adapt to different working environments and scanning requirements, and improving the quality and efficiency of tunnel radar scanning.

[0039] In the invention, first, the device is placed in the support cover 1, and then the clamping threaded sleeve 26 is rotated. The clamping screw rod 27 drives the clamping plate 25 to move, realizing the clamping and fixing of devices of different sizes. The operator then rotates the handwheel 11, driving the active gear 10 in the mounting box 5 to rotate. The active gear 10 meshes with the driven gear 9 at one end of the lifting screw rod 4. Since the diameter of the driven gear 9 is larger than the diameter of the active gear 10, a labor-saving transmission is achieved, enabling the lifting screw rod 4 to rotate in the fixed cylinder 6. Because the lifting screw rod 4 is threadedly connected to the threaded groove 8 in the lifting column 3, and the lifting column 3 is slidably connected to the fixed cylinder 6, the lifting column 3 slides up and down in the fixed cylinder 6, realizing the lifting of the support cover 1. The support cover 1 is connected above the lifting column 3 through two hinged hydraulic rods 7, which can flexibly adjust the angle. A plurality of universal wheels 12 below the pushing platform 2 facilitate the movement of the bracket. The guide wheels 17 roll to reduce friction. The guide seat 18 slides in the guide groove 23 to ensure the accurate movement direction. The spring 22 buffers and dampens vibrations. The pressure sensor 24 feeds back pressure information. When it is necessary to place the bracket on a mobile vehicle, the propping threaded sleeve 29 is rotated. The propping screw rod 30 drives the propping plate 28 to descend and abut against the placement end of the mobile vehicle, thereby propping up the entire bracket, and further realizing the stable support, flexible adjustment, and accurate movement of the radar antenna, meeting the tunnel radar scanning requirements.

[0040] The above-disclosed is only a preferred embodiment of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
