Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, specifically to a device for detecting surface damage to bridge cables. Background Technology

[0002] Bridge cables, also known as cable stays, are the main load-bearing components that directly transfer the weight of the main girder and deck of a cable-stayed bridge to the towers. The cables of a cable-stayed bridge are usually made of steel cables, and their forms vary depending on their composition. They can be composed of parallel steel wires, parallel steel cables, single steel cables, steel wire ropes, closed steel cables, or solid steel bars.

[0003] Chinese Patent No. CN222774507U discloses an auxiliary device for detecting physical damage to the surface of bridge cables. The device includes a housing, a traveling mechanism, and a camera mechanism. The housing is a hollow, protruding structure with two coaxial through holes through which the cable passes and is positioned inside the housing. The traveling mechanism is located inside the housing cavity, with its working end contacting the cable. The camera mechanism consists of several camera ends mounted on a circular guide rail. The camera ends of the camera mechanism are movably mounted on the circular guide rail, which is located in the center of the housing, with the camera ends facing the cable axis. This invention employs a moving structure, a rotating structure, and a rolling structure, solving the problems of inconvenient installation and safety hazards associated with physical damage detection auxiliary devices.

[0004] However, the above technical solutions only solve the problems of inconvenient installation and safety hazards of physical damage detection auxiliary devices by adopting moving, rotating and rolling structures. However, during the process of the moving structure moving along the cable, some cables will have cable clamps, which will obstruct the equipment. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a device for detecting surface damage of bridge cables.

[0006] The technical solution of this utility model is as follows: A device for detecting surface damage of bridge cables includes two parallel limiting rings connected to each other by a mounting frame. Multiple cameras are connected to the mounting frame. Each limiting ring is composed of two arc-shaped plates joined together. Multiple moving components are distributed around the limiting rings and connected to the arc-shaped plates. Each moving component includes a mounting plate, a swing plate, a support plate, an elastic element, and a driving element. The support plate is connected to the inner wall of the arc-shaped plate. One end of each of the two parallel swing plates is rotatably connected to the support plate, and the support plate is rotatably connected to the other end of the two swing plates. The support plate, swing plates, and mounting plate form a parallelogram structure. Both ends of the elastic element are rotatably connected to the mounting plate and the support plate, respectively. The driving element is connected to the mounting plate. In use, the moving components drive the parallelogram structure and the arc-shaped plates to move along the cable. The expansion and contraction of the elastic element causes the parallelogram structure to deform and pass over the cable clamp protrusion.

[0007] Preferably, the driving component consists of a driving wheel, a driven wheel, a driving device, and a synchronizing component. Both the driving wheel and the driven wheel are rotatably connected to the mounting plate. The driving device is connected to the mounting plate, and the output end of the driving device is connected to the driving wheel. The synchronizing component is connected to both the driving wheel and the driven wheel.

[0008] Preferably, the synchronizing element consists of a synchronizing pulley and a synchronizing belt. The two synchronizing pulleys are connected to the shafts of the driving pulley and the driven pulley, and the synchronizing pulleys are connected to the synchronizing belt for transmission.

[0009] Preferably, both the driving wheel and the driven wheel are provided with V-shaped grooves.

[0010] Preferably, the included angles of the V-grooves of the driving wheel and the driven wheel are different, with the included angle of the V-grooves of the driving wheel being 150 degrees and the included angle of the V-grooves of the driven wheel being 135 degrees.

[0011] Preferably, multiple fill lights are connected to the mounting bracket.

[0012] Preferably, both the front and rear limiting rings are connected to a connecting seat, which is connected to any arc plate. One end of the connecting rod is rotatably connected to the connecting seat, and the other end of the connecting rod is connected to a counterweight.

[0013] Preferably, the counterweight has a cavity for receiving, and the cavity is filled with damping fluid.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0015] In this invention, a quadrilateral structure consisting of an mounting plate, a swing plate, and a support plate is provided inside the limiting ring. The quadrilateral structure can deform during the movement along the cable by means of elastic elements. The deformation allows it to pass over the protrusion formed by the cable clamp on the cable. While deforming, it can still maintain the clamping of the cable and allow normal movement. Attached Figure Description

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model proposes a device for detecting surface damage to bridge cables, comprising a limiting ring 1, a mounting frame 2, a camera 3, and a moving component. Two limiting rings 1 are arranged in parallel, connected to the mounting frame 2. Multiple cameras 3 are connected to the mounting frame 2. The limiting ring 1 is composed of two arc-shaped plates 4 joined together. Multiple moving components are distributed around the limiting ring 1 and connected to the arc-shaped plates 4. Each moving component includes a mounting plate 5, a swing plate 6, a support plate 7, an elastic element 8, and a driving element 9. The support plate 7 is connected to the arc-shaped plate 4. On the inner wall, two parallel swing plates 6 are rotatably connected at one end to the support plate 7, and the support plate 7 is rotatably connected to the other end of the two swing plates 6. The support plate 7, the swing plates 6 and the mounting plate 5 form a parallelogram structure. The two ends of the elastic element 8 are respectively connected to the mounting plate 5 and the support plate 7 by rotating hinges. The elastic element 8 is selected from, but is not limited to, gas springs. The driving element 9 is connected to the mounting plate 5. When the moving component is in use, the moving element drives the parallelogram structure and the arc plate 4 to move along the cable. The elastic element 8 extends and retracts, causing the parallelogram structure to deform and pass over the cable clamp protrusion.

[0023] In an optional embodiment, a plurality of fill lights 17 are connected to the mounting bracket 2; the fill lights 17 provide fiber optic enhancement to improve image quality in cloudy or poor lighting conditions.

[0024] In an optional embodiment, a connecting seat 18 is connected to both the front and rear limiting rings 1. The connecting seat 18 is connected to any one of the arc-shaped plates 4. One end of the connecting rod 19 is rotatably connected to the connecting seat 18, and the other end of the connecting rod 19 is connected to a counterweight 20. The counterweight 20 can point vertically to the ground when the device moves along the inclined cable, maintaining its state during movement.

[0025] In an optional embodiment, the counterweight 20 has a receiving cavity 21, and the receiving cavity 21 is filled with a damping liquid; the damping liquid is a silicone oil-based solution with a viscosity of 500-1500 cSt.

[0026] Example 2

[0027] like Figures 2-4 As shown, this utility model proposes a device for detecting surface damage to bridge cables. Compared to Embodiment 1, this embodiment describes the detailed structure of the moving component.

[0028] The drive component 9 consists of a driving wheel 10, a driven wheel 11, a drive device 12, and a synchronizing element 13. Both the driving wheel 10 and the driven wheel 11 are rotatably connected to the mounting plate 5, and the drive device 12 is connected to the mounting plate 5. The drive device 12 is a motor. The output end of the drive device 12 is connected to the driving wheel 10, and the synchronizing element 13 is connected to both the driving wheel 10 and the driven wheel 11. The drive component 9 is installed in some quadrilateral structures, but not all quadrilateral structures are equipped with the drive component 9. This reduces the cost of the drive device 12 while ensuring normal operation.

[0029] In an optional embodiment, the synchronizing element 13 consists of a synchronizing pulley 14 and a synchronizing belt 15. The two synchronizing pulleys 14 are connected to the shafts of the driving pulley 10 and the driven pulley 11, and the synchronizing pulleys 14 are connected to the synchronizing belt 15 for transmission.

[0030] In an optional embodiment, both the driving wheel 10 and the driven wheel 11 are provided with V-grooves 16; the V-grooves 16 can provide better clamping and anti-slip effects, preventing the equipment from slipping off the cable.

[0031] In an optional embodiment, the included angles of the V-grooves 16 of the driving wheel 10 and the driven wheel 11 are different. The included angle of the V-grooves of the driving wheel 10 is 150 degrees, and the included angle of the V-grooves of the driven wheel 11 is 135 degrees. The difference in angle between the driving wheel 10 and the driven wheel 11 is to increase traction and reduce resistance, thereby improving the overall performance through the difference in their angles.

[0032] In summary, when using this utility model, the operator unfolds the arc-shaped plate 4 via a hinge and places it on the cable. Then, the two fixing parts are fixed with bolts to form a limiting ring 1. At this time, the counterweight 20 points vertically to the ground to ensure the angle of the equipment. Then, the operator controls multiple drive devices 12 via a remote control to start and drive the drive wheel 10 to rotate. The drive wheel 10 drives the synchronous wheel 14 to rotate via the synchronous belt 15, which in turn drives the driven wheel 11 to rotate. When they rotate, they move along the cable. Their movement drives the limiting ring 1 and the mounting frame 2 to move. The supplementary light 17 on the mounting frame 2 can provide optical fiber to improve image quality. The camera 3 captures images to facilitate the operator's inspection of damage to the cable surface. During its movement, as its position or angle changes, the connecting rod 19 can change a certain angle with its hinge connection as the center, so that the counterweight 20 can keep pointing vertically to the ground to help the overall equipment maintain balance. The liquid in the cavity 21 can also keep the counterweight 20 stable and prevent it from swinging too much.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
