Description

Technical Field

[0001] The present invention relates to the technical field of main cable detection, and in particular to a bridge main cable detection and repair device. Background Art

[0002] With the development of China's economy, a large number of long-span bridges have emerged. Bridge safety has become a core issue of national economy and national security. Bridge damage detection is a prerequisite for ensuring bridge safety. Suspension bridges have become the preferred solution for extra-large bridges due to their flexible construction, beautiful appearance, strong adaptability and good navigability. The main cable is the main load-bearing structure of the suspension bridge. The main cable system is more sensitive to external damage. It is affected by natural factors such as wind, rain, freezing, temperature and humidity changes all year round, which will cause certain erosion to the main cable. Its durability will directly affect the safety of the entire bridge. In order to ensure the safe operation of the bridge, the main cable should be regularly inspected and maintained.

[0003] At present, the maintenance of the main cable mainly relies on manpower. The technicians walk on the main cable to inspect it, or use telescopes and other equipment to inspect it on the bridge deck. The bottom of the main cable cannot be observed at close range, which is inefficient and ineffective. It is easy to miss something and is time-consuming and labor-intensive.

[0004] With the development of robot technology, people have begun to study the application of robots for auxiliary inspection and repair. However, when inspecting the main cable, the existing equipment is generally unable to inspect it in a circular manner on the outer wall of the cable, which is prone to the loss of inspection angles, and after the defect is detected, it is impossible to repair the defect synchronously, which is of poor practicality. At the same time, dust is easily adhered to the surface of the main cable, and the defect cannot be clearly displayed during inspection and repair. The surface of the main cable needs to be cleaned by cleaning equipment, and the dust generated during cleaning is very easy to adhere to the surface of the inspection equipment, affecting the inspection quality of the inspection equipment.

When the moving part 4 controls the inspection part 1 to move horizontally on the main cable body 2, the two inspection semi-rings 10 and the two connecting semi-rings 12 in the inspection part 1 are arranged in a ring shape. The first motor 17 works and, with the cooperation of the first bevel gear set 18, controls the driving rod 19 to drive the two driving gears 20 to rotate, thereby meshing and transmitting a plurality of lower gear rings 15 and a plurality of upper gear rings 16, and driving the two upper rotating rings 14 and the two lower rotating rings 13 to rotate in the two inspection semi-rings 10 and the two connecting semi-rings 12, so that the two visual inspection cameras 21 can rotate outside the main cable body 2 for inspection, thereby ensuring the inspection effect of the main cable body 2, and thereby enabling the visual inspection cameras 21 to accurately collect images of main cable diseases, making it convenient for the system to retrieve data for large model training, so that the robot can make maintenance strategy decisions on its own.

[0060] The plurality of guide wheels 28 are respectively against the two handrail ropes 3;

[0061] The other control box 29 is fixedly connected to the control frame 27. When the clamping rod in one of the control boxes 29 clamps the two handrail ropes 3, the position of the control box 29 is restricted. At this time, the two first electric push rods 32 work to control the other control box 29 to move away from the control box 29, so that the position of the control frame 27 connected to the other control box 29 is moved synchronously, and the detection part 1 is driven to move at the same time under the connection of the horizontal adjustment component 5; and when the two first electric push rods 32 work to push the control box 29 to move, the cooperation of the two first slide rails 31 and the two first sliders 30 can ensure the stability of the control box 29 when moving, and when the control frame 27 moves, a number of guide wheels 28 will rotate and move on the two handrail ropes 3, effectively improving the stability of the control frame 27 when moving, and ensuring the stability of the detection of the main cable body 2 by the detection part 1.

When in use, the second motor 37 drives the two bidirectional screw rods 34 in the control box 29 to rotate through the second bevel gear set 38, so that the several clamping blocks 36 threadedly connected with the two bidirectional screw rods 34 will move in the two slide grooves 35, so that the two clamping blocks 36 on the single bidirectional screw rod 34 are close to each other to clamp the handrail rope 3. Under the intermittent operation of the two second motors 37, the two clamping assemblies can intermittently clamp the handrail rope 3.

[0064] Optionally, the horizontal adjustment component 5 includes an adjustment slot 39 opened on the control frame 27, two second electric push rods 40 symmetrically fixed on the lower surface of the control frame 27, two L-shaped control plates 41 symmetrically arranged on the upper surface of the control frame 27, two second slide rails 42 symmetrically fixed on the upper surface of the control frame 27, and a plurality of second sliders 43 respectively fixedly connected to the two L-shaped control plates 41 and respectively slidably connected to the two second slide rails 42;

While the cleaning brushes 53 are cleaning, the air pump 48 works to extract the air in the filter box 46. At this time, the solenoid valve 52 closes the guide tube 51 and makes the delivery tube 50 in a through state. Under the action of the delivery tube 50, the two arc-shaped dust suction boxes 45 generate negative pressure, so that the dust cleaned by the cleaning brushes 53 can enter the two arc-shaped dust suction boxes 45 under control. The dust is filtered by a plurality of filter plates 47 to prevent dust from adhering to the two visual inspection cameras 21 when the main cable body 2 is cleaned, thereby affecting the subsequent inspection quality.

[0070] The two ends of the reset spring 57 are fixedly connected to the inner wall of the movable groove 55 and the other end of the support rod 56 respectively. When the two detection half rings 10 and the two connecting half rings 12 are close to each other for detection and repair of the main cable body 2, the plurality of rotating beads 58 will contact the main cable body 2. Under the elastic force of the plurality of reset springs 57, the plurality of support rods 56 push the plurality of rotating beads 58 to contact the main cable body 2. The detection part 1 can move horizontally on the main cable body 2, and the two upper rotating rings 14 and the two lower rotating rings 13 can be effectively supported when rotating, thereby ensuring the stability of the detection part 1 during operation.

[0071] Optionally, the support assembly 6 includes two assembly seats 59 symmetrically fixed on the two control frames 27, two third electric push rods 60 respectively mounted on the two assembly seats 59, two support frames 61 respectively fixed at the telescopic ends of the two third electric push rods 60, a plurality of support wheels 62 respectively rotatably mounted on the two support frames 61, and a plurality of guide rods 63 respectively slidably mounted on the two assembly seats 59 and fixedly connected to the two support frames 61 at the lower ends. When the detection unit 1 moves and detects the main cable body 2, the two third electric push rods 60 will control the two support wheels 62 to abut against the main cable body 2 and rotate on the main cable body 2, thereby improving the movement without aligning with the movement of the detection unit 1. When the detection part 1 and the moving part 4 pass through the cable clamp on the main cable body 2, the third electric push rod 60 can drive the support frame 61 and the support wheel 62 to move upward, so that the support wheel 62 can pass over the cable clamp, which is convenient for the detection part 1 and the moving part 4 to move smoothly on the main cable body 2. When the third electric push rod 60 controls the support frame 61 and the support wheel 62 to move in the vertical direction, the plurality of guide rods 63 provided can play a role of guiding and limiting, ensuring the stability of the support frame 61 and the support wheel 62 in the direction of movement. At the same time, it can ensure the stability of the control frame 27 supported by the two third electric push rods 60, the two support frames 61 and the plurality of support wheels 62, and further ensure the stability of the detection part 1 and the moving part 4 when in use.

[0072] Optionally, the detection unit 1 further includes two fourth electric push rods 64 respectively hinged on the two L-shaped control plates 41;

[0073] The telescopic ends of the two fourth electric push rods 64 are respectively hinged to the two connecting half rings 12. When the moving part 4 needs to control the detection part 1 to pass through the cable clamp on the main cable body 2, the two fourth electric push rods 64 work, pull the two connecting half rings 12 to rotate, and approach the two L-shaped control plates 41 respectively, so that the detection part 1 is controlled, so that the detection part 1 will not collide with the cable clamp when moving, which facilitates the movement of the detection part 1 on the main cable body 2. When the detection part 1 is working, the two fourth electric push rods 64 work, push the two connecting half rings 12 to collide with each other, and then facilitate the rotation of the two wire rotating rings, the two upper rotating rings 14 and the several lower gear rings 15 and the several upper gear rings 16, thereby completing the driving of the cleaning component 7 and the control of the position of the repair component 9 and the two visual detection cameras 21.
