Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, specifically to a rotatable and adjustable mounting bracket for a cable-stayed bridge vision sensor. Background Technology

[0002] The stay cable is one of the core load-bearing components of a cable-stayed bridge, connecting the towers and the main beams and playing a crucial role in the transfer of bridge loads. It is usually made of high-strength steel strands or parallel steel wires, such as epoxy-coated steel strands (standard strength can reach 2000MPa) or PE-protected steel wire cables. The installation of stay cables usually includes steps such as cableway positioning, cable hanging, tensioning, and cable adjustment. The construction accuracy requirements are high. The design and construction of stay cables directly affect the safety, economy, and durability of the bridge. The stay cable vision sensor mounting bracket is a special structure used to fix cameras, displacement monitoring equipment, or other vision sensors. It usually needs to meet the requirements of stability, durability, and maintainability.

[0003] Extensive research revealed problems with existing mounting brackets. Due to high wind speeds on bridges, the visual sensors, mounted on the stay cables via brackets, are subject to rotation caused by the strong winds. This can lead to the sensors deviating from their preset angles, making it difficult to monitor the stay cables and resulting in decreased monitoring accuracy. Therefore, based on the aforementioned research and existing technologies, a rotatable and adjustable mounting bracket for stay cable visual sensors is proposed to address these issues.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In one typical implementation of this application, please refer to Figures 1-4A rotatable and adjustable cable-stayed bridge vision sensor mounting bracket includes a clamp 1. The bottom surface of clamp 1 is rotatably connected to clamp 2 via a pin. Clamp 1 can be separated by removing the pin. Connecting blocks 6 are fixedly installed on the outer circular wall surfaces of clamp 1 and clamp 2. Two screws 7 are threadedly connected to the top surfaces of the two connecting blocks 6. A support box 8 is fixedly installed on the outer circular wall surface of clamp 1. The operator rotates clamp 1 and clamp 2 and places them on the cable-stayed bridge. The operator places the screws 7 on the two connecting blocks 6 and rotates the screws 7 to fix clamp 1 and clamp 2 on the cable-stayed bridge. A gimbal 13 for mounting the vision sensor is provided on the top surface of the support box 8. An angle adjustment mechanism 9 is provided on the top surface of the support box 8 for adjusting the angle of the gimbal 13.

[0022] The angle adjustment mechanism 9 includes a support frame 10, which is set on the top surface of the support box 8. The inside of the support frame 10 is rotatably connected to a movable seat 12 via a rotating shaft. The top surface of the movable seat 12 is fixedly connected to the bottom surface of the gimbal 13. One side of the movable seat 12 is coaxially connected to a gear 11 via a rotating shaft. The outer circular wall of the gear 11 is meshed with a gear 31. A drive motor 32 for driving the gear 31 to rotate is installed on one side of the inside of the support frame 10. One end of the drive shaft of the drive motor 32 passes through one side of the support frame 10 and is fixedly connected to one side of the gear 31.

[0023] Among them, the second drive motor 32 drives the second gear 31 to rotate, and the rotation of the second gear 31 drives the gimbal 13 and the vision sensor on it to rotate through the first gear 11, thereby adjusting the pitch angle of the vision sensor.

[0024] The movable seat 12 has several snap-fit ​​slots 30 on one side, and the support frame 10 has an installation block 20 on one side. Several snap-fit ​​posts 21 are fixedly installed at one end of the installation block 20. One end of the snap-fit ​​post 21 passes through the support frame 10 and is movably snapped into the snap-fit ​​slots 30. The other end of the installation block 20 is fixedly installed with a support frame 22. Two positioning blocks 25 are fixedly installed on the bottom surface of the support frame 22. A movable plate 26 is rotatably connected between the two positioning blocks 25 through a rotating shaft. Two installation plates 27 are fixedly installed on one side of the support frame 10. The two sides of the movable plate 26 are rotatably connected to the installation plates 27 through rotating shafts. Two positioning plates 28 are fixedly installed on one side of the support frame 10. An electric push rod 29 is rotatably connected between the two positioning plates 28 through a rotating shaft. One end of the telescopic shaft of the electric push rod 29 is connected to one side of the movable plate 26 through a universal joint. A wind speed sensor 19 for detecting wind speed is fixedly installed on one side of the support frame 10.

[0025] An information processing module is fixedly installed on one side of the inside of the support box 8. The wind speed sensor 19, drive motor 14 and electric push rod 29 are all electrically connected to the information processing module.

[0026] In the above process, by setting a wind speed threshold for the wind speed sensor 19, when the wind speed exceeds the threshold, the telescopic axis of the electric push rod 29 moves outward, which in turn drives the support frame 22 through the movable plate 26 to move the mounting block 20 and the snap-fit ​​post 21 inward into the snap-fit ​​groove 30, thereby fixing the angle of the gimbal 13 and the vision sensor and preventing them from rotating due to the high wind speed.

[0027] Preferably, by using the set gimbal 13, the staff installs the visual sensor on the gimbal 13 and fixes clamp 1 and clamp 2 to the cable. The staff uses the visual sensor to monitor the cracks on the cable. During the monitoring process, drive motor 2 32 starts, the drive shaft of drive motor 2 32 rotates and drives gear 2 31 to rotate, gear 2 31 rotates and drives gear 11 to rotate, gear 11 rotates and drives movable seat 12 and gimbal 13 to rotate, adjusting the pitch angle of the visual sensor to better monitor the cable.

[0028] Meanwhile, the wind speed sensor 19 continuously detects the wind speed. The staff sets a threshold wind speed for the wind speed sensor 19. When the wind speed exceeds the threshold, the telescopic axis of the electric push rod 29 moves outward, causing the lower end of the movable plate 26 to move outward. At the same time, the electric push rod 29 rotates between the two positioning plates 28. The lower end of the movable plate 26 rotates outward, causing the movable plate 26 to rotate around the mounting plate 27. Meanwhile, the upper end of the movable plate 26 moves the support frame 22 inward through the positioning block 25. The inward movement of the support frame 22 causes the mounting block 20 and the locking post 21 to move inward. The locking post 21 moves inward and enters the locking groove 30 on the side of the movable seat 12, thereby restricting the position of the movable seat 12 and the gimbal 13. This restricts the position of the vision sensor on the gimbal 13, preventing the vision sensor from rotating due to high wind speed. This improves the accuracy of adjusting the vision sensor and achieves the effect of adjusting the angle of the vision sensor, which helps the staff to monitor the cable-stayed bridge using the vision sensor.

[0029] Two support bars 23 are fixedly installed on one side of the support frame 10, and a support rod 24 is fixedly installed between the two support bars 23. The support frame 22 is slidably connected to the support rod 24.

[0030] Preferably, the support frame 22 is set so that its movement will be along the support rod 24 between the two support bars 23. The support bars 23 and the support rod 24 cooperate to restrict the movement of the support frame 22, thereby achieving the effect of restricting the support frame 22.

[0031] Inside the support box 8, a lead screw 17 is rotatably connected via bearings. A drive motor 14 for driving the lead screw 17 is installed on one side of the support box 8. One end of the telescopic shaft of the drive motor 14 passes through the support box 8 and is fixedly connected to one end of the lead screw 17. A support block 16 is threadedly connected to the outer circular wall of the lead screw 17. The top surface of the support block 16 is fixedly connected to the bottom surface of the support frame 10. A rectangular hole is opened on the top surface of the support box 8. The support block 16 is slidably connected to the rectangular hole. The drive motor 14 is electrically connected to the information processing module. Through the cooperation of the drive motor 14 and the lead screw 17, the support block 16 can drive the pan-tilt unit 13 to move horizontally along the lead screw 17, which facilitates expanding the range of the visual sensor monitoring the inclined bolt.

[0032] A limiting rod 18 is fixedly installed inside the support box 8. The limiting rod 18 is slidably connected to the support block 16, and the limiting rod 18 can restrict the movement of the support block 16.

[0033] Preferably, the drive motor 14 is configured to rotate, which in turn drives the lead screw 17 to rotate. The rotation of the lead screw 17 causes the support block 16 to move along the lead screw 17 and the limiting rod 18. The limiting rod 18 can restrict the movement of the support block 16. The movement of the support block 16 also causes the support frame 10 to move. The movement of the support frame 10 causes the pan-tilt unit 13 and the vision sensor on it to move, thereby adjusting the position of the vision sensor laterally and expanding the range of the vision sensor monitoring the inclined bolt.

[0034] A protective cover 15 is bolted to one side of the support box 8. The protective cover 15 can protect the drive motor 14 and prevent it from being damaged by debris. Two rubber plates 3 are fixedly sleeved on the inner circular wall of clamp 1 and clamp 2. The rubber plates 3 can increase the friction between clamp 1 and clamp 2 and the cable, and improve the stability of clamp 1 and clamp 2 on the cable.

[0035] The bottom outer circular wall of clamp 2 is threaded with a threaded rod 4, and a rubber block 5 is fixedly installed on the top surface of the threaded rod 4. The inclined cable can be abutted by the cooperation of the threaded rod 4 and the rubber block 5.

[0036] Preferably, by using the threaded rod 4, the operator rotates the threaded rod 4 to drive the rubber block 5 to rotate. The rotation of the threaded rod 4 also causes the rubber block 5 to move upward until it comes into contact with the outer wall of the cable, increasing the friction between clamp 1 and clamp 2 and the cable, and preventing clamp 1 and clamp 2 from shifting on the cable.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
