Description

Technical Field

[0001] The utility model relates to the technical field of bridge steel cable flaw detection, in particular to a bridge steel cable flaw detection device. Background Art

[0002] Cable-stayed bridges are an important structural form of modern long-span bridges, especially in places where it is difficult to build bridge piers, such as across canyons, bays, and large rivers. However, as the service life of cable-stayed bridges increases, the unsafe factors caused by the wear and tear between the steel wires in the cables, rust and breakage of wires, and impact deformation caused by traffic accidents will become increasingly serious. In order to ensure safety, it is necessary to use flaw detection equipment to regularly inspect the cables.

[0003] When using existing bridge cable flaw detection devices, fixing bolts and protective frames are usually used to fix the flaw detection device to the climbing wheel frame. The position of the flaw detection device is fixed before detection. After climbing to the steel cable, the flaw detection device may be offset following the climbing frame due to shaking or strong winds, making it difficult to adjust the position of the flaw detection device, resulting in poor detection effect. A secondary inspection may be required later, affecting the detection efficiency. In addition, the flaw detection device is fixed on the wheel frame, and the steel cable can only be inspected and photographed from one direction, with low flexibility. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a bridge cable flaw detection device includes an adjustment component 2 arranged on the outer ring of the cable body 1, and the adjustment component 2 includes two climbing wheel frames 3, and the two climbing wheel frames 3 are respectively installed on the outer ring of the cable body 1;

[0025] The opposite sides of the climbing wheel frame 3 are rotatably mounted with a rotating shaft 4 near the upper and lower ends, and the outer ring of the rotating shaft 4 is mounted with a climbing wheel body 5 near the front and rear ends, and the front and rear opposite surfaces of the climbing wheel bodies 5 are in contact with the outer ring of the steel cable body 1, and the tops of the two climbing wheel frames 3 are fixedly connected with a connecting frame 12, and the tops of the two connecting frames 12 are provided with a slide groove;

[0026] A movable plate 13 is slidably installed on the top of the connecting frame 12 through a slide groove, and an electric telescopic rod 14 is installed on the top of the movable plate 13 through a support plate. A mounting box 15 is installed at the end of the push rod of the electric telescopic rod 14, and a flaw detection and shooting device is installed inside the mounting box 15. An adjusting motor 16 is installed on the top of the movable plate 13, and a driving gear 17 is installed at the bottom end of the driving shaft of the adjusting motor 16. A driven gear 18 meshing with the driving gear 17 is installed on the outer ring of the connecting frame 12 and on the upper position of the side away from the steel cable body 1. The driving shaft of the adjusting motor 16 is meshed and connected with the connecting frame 12 through the driving gear 17 and the driven gear 18.

[0027] In this embodiment, a mounting plate 6 is fixedly connected to the rear position of one side of the climbing wheel frame 3 close to one side of the steel cable body 1, and a fixing plate is fixedly connected to the front position of one side of the climbing wheel frame 3 close to the other side of the steel cable body 1. A clamping motor 7 is fixedly installed on the side of the mounting plate 6 away from the steel cable body 1. The driving shaft of the clamping motor 7 passes through the two sides of the mounting plate 6 and is connected to a threaded rod 8. By starting the clamping motor 7 in forward or reverse rotation, the driving shaft of the clamping motor 7 rotates to drive the threaded rod 8 to rotate, so that the other climbing wheel frame 3 can be moved away from or close to one of the climbing wheel frames 3, which is convenient for adjustment.

[0028] In this embodiment, one end of the threaded rod 8 away from the clamping motor 7 passes through both sides of the fixed plate and is threadedly connected to the fixed plate. Sliding rods are installed at the upper and lower ends of both sides of the fixed plate. One side of the sliding rod is fixedly connected to the mounting plate 6, and the other side is connected to the reinforcement plate through the fixed plate. By setting the sliding rod 1, it is convenient to improve the moving stability of the climbing wheel frame 3 and avoid the climbing wheel frame 3 from tilting and deviating.

[0029] In this embodiment, bearings are provided at the connection between the threaded rod 8 and the reinforcement plate, and at the connection between the drive shaft of the clamping motor 7 and the mounting plate 6, and the drive shaft of the clamping motor 7 and the threaded rod 8 are rotatably connected to the mounting plate 6 and the reinforcement plate respectively through bearings. The provided bearings can prevent the mounting plate 6 and the fixed plate from affecting the rotation of the drive shaft of the clamping motor 7 and the threaded rod 8, thereby improving the rotation stability.

[0030] In this embodiment, a transmission wheel box 11 is installed at the front end of the climbing wheel frame 3 close to the other side of the steel cable body 1, and a transmission wheel group is arranged in the transmission wheel box 11. A climbing motor 10 is installed on one side of the transmission wheel box 11. The driving shaft of the climbing motor 10 is connected to the two rotating shafts 4 through the transmission wheel group. By starting the climbing motor 10, the driving shaft of the climbing motor 10 drives the climbing wheel body 5 to rotate, thereby driving the installation box 15 to move on the steel cable body 1, which is convenient for flaw detection and photography of the steel cable body 1.

[0031] In this embodiment, the inner sides of several climbing wheel bodies 5 are conical settings that match the steel cable body 1, and the outer ring of the conical part of the climbing wheel body 5 is provided with an anti-slip rubber sleeve. The anti-slip rubber sleeve is provided to facilitate improving the contact friction between the climbing wheel body 5 and the steel cable body 1, thereby improving the movement stability.

[0032] In this embodiment, a battery box 9 is installed at the front end of the climbing wheel frame 3 close to the side of the steel cable body 1, and an electric control box is arranged on the side of the battery box 9 away from the steel cable body 1. The electric control box is electrically connected to the climbing motor 10, the electric telescopic rod 14, the adjustment motor 16, the battery box 9, and the clamping motor 7. The battery box 9 can provide power for easy use.

[0033] It should be noted that the utility model is a bridge cable flaw detection device. When in use, first, the clamping motor 7 can be started according to the size of the cable body 1, because one of the climbing wheel frames 3 is installed with the clamping motor 7 through the mounting plate 6, and the driving shaft of the clamping motor 7 is connected with the threaded rod 8, and the threaded rod 8 is threadedly connected with the other climbing wheel frame 3, so that the threaded rod 8 can be driven to rotate by the driving shaft of the clamping motor 7, so that the other climbing wheel frame 3 is pushed away from the one climbing wheel frame 3 by the thread, until it reaches the appropriate installation position, then the clamping motor 7 is stopped, and the climbing wheel frame 3 is installed on the cable body 1, and the cable body 1 is placed between the two climbing wheel bodies 5;

[0034] Then, the clamping motor 7 is started in reverse, so that the driving shaft drives the threaded rod 8 to reverse, thereby driving the other climbing wheel frame 3 to approach one of the climbing wheel frames 3. Since the climbing wheel body 5 is installed on the climbing wheel frame 3, the climbing wheel body 5 is driven to move in the direction close to the steel cable body 1, thereby fixing the climbing wheel frame 3 to the steel cable body 1. After the climbing wheel body 5 reaches a suitable clamping position, the flaw detection and shooting equipment installed at the installation box 15 can be opened;

[0035] At the same time, because the rotating shaft 4 of the climbing wheel body 5 is connected to the climbing motor 10 through the transmission wheel box 11, the climbing motor 10 can be started after the flaw detection equipment works normally and ensures safety, and the climbing motor 10 drives the climbing wheel body 5 to rotate, thereby driving the climbing wheel frame 3 to move. Since the installation box 15 is installed on the climbing wheel frame 3 through various devices, the movement of the climbing wheel frame 3 drives the installation box 15 to move on the steel cable body 1, so as to perform flaw detection and shooting on the steel cable body 1;

[0036] When the distance between the installation box 15 and the cable body 1 needs to be adjusted, the electric telescopic rod 14 can be started. Since the push rod end of the electric telescopic rod 14 is connected to the installation box 15, the installation box 15 can be moved away from or close to the cable body 1 by the push rod extension of the electric telescopic rod 14, thereby adjusting the flaw detection distance.

[0037] At the same time, when adjusting the flaw detection shooting position of the installation box 15, because the installation box 15 is installed on the movable plate 13, the movable plate 13 is slidably installed in the connecting frame 12, and an adjusting motor 16 is installed on the movable plate 13, and at the same time, a driving gear 17 is connected to the end of the driving shaft of the adjusting motor 16, and the driving gear 17 is meshed with the driven gear 18, so that the driving gear 17 can be driven to rotate by the adjusting motor 16, so that the meshing transmission drives the movable plate 13 to slide on the connecting frame 12, and the position of the installation box 15 is adjusted;

[0038] When the position of the mounting box 15 changes due to wind or other shaking at the climbing wheel frame 3, the mounting box 15 can be adjusted to a suitable position again to improve the detection effect. At the same time, there is no need to remove it for adjustment, thereby improving the efficiency of flaw detection. When flaw detection is performed on the steel cable body 1, the distance and position of the mounting box 15 on the outer ring of the steel cable body 1 can be adjusted according to the above steps, so that the steel cable body 1 can be photographed and flaw detected from different directions and distances, thereby improving the use effect.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
