Description

Technical Field

[0001] This utility model relates to the field of bridge cable testing technology, and in particular to a bridge cable testing device. Background Technology

[0002] Bridge cables are an important component of bridge structures, playing a crucial role, especially in cable-stayed and suspension bridges. Their main function is to bear and transmit loads from the bridge deck and vehicles traveling on it, and to maintain the stability of the bridge through the tension of the cables.

[0003] To ensure the continued safety of bridge cables after prolonged use, a bridge cable inspection device is needed. For example, Chinese Patent Publication No. CN220399253U discloses a distributed vehicle bridge cable inspection system, comprising several transport trolleys encircling the cable and cable ties connecting the trolleys. Each transport trolley includes a body, a camera at one end of the body, and a drive mechanism. This invention allows for the selection of the number of transport trolleys based on the cable thickness. Several trolleys are connected together and installed on the cable. As the trolleys move, the entire device crawls along the cable, while the camera collects images to determine the cable condition.

[0004] However, in actual operation, considering that the cable diameters used in different bridges are not the same, the main body is driven by wheel sets. However, the height of the wheel sets cannot be adjusted. This means that the detection device can only clamp cables of a fixed diameter. If the cable is too thick or too thin, it will be unable to clamp or the clamping force will be insufficient, resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the height of the wheel sets cannot be adjusted, resulting in poor adaptability, and to propose a bridge cable detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a bridge cable inspection device, including an inspection frame, the inspection frame is composed of a pair of frame bodies, the pair of frame bodies are arranged opposite each other and are hinged and rotated between them and fixed by fasteners, a pair of moving devices are fixed inside the frame body, and a support plate is provided between the moving devices;

[0008] The moving device includes traction wheels, with the traction wheels on both sides used to press against the cable to drive the detection frame to move;

[0009] The frame is equipped with an adjustment component for adjusting the height of a pair of traction wheels, and the support plate is equipped with a rust-preventing mechanism for applying oil to the cables.

[0010] Furthermore, the adjustment assembly includes a dual-axis motor fixedly mounted on the side of the frame, and brackets fixed on both sides of the dual-axis motor. The side of the bracket has an extension, and a slide block is slidably connected to the extension. The shaft end of the dual-axis motor passes through the bracket and is fixedly mounted with a lead screw, which is threadedly connected to the slide block.

[0011] Furthermore, it also includes a support rod and a connecting rod. The two ends of the support rod are rotatably connected to the base of the traction wheel and the two sides of the slide, respectively. The connecting rod is rotatably connected to the side of the frame, and its other end is rotatably connected to the middle of the support rod.

[0012] Furthermore, the rust prevention mechanism includes a guide rod, the support plate is located above the dual-axis motor and is slidably connected to the frame through the guide rod, the other end of the guide rod is fixed with a limit block and a support spring is sleeved around it, and the two ends of the support spring abut against the frame and the support plate.

[0013] Furthermore, a pair of support plates are arranged opposite each other, and their opposite ends have an arc-shaped structure for closing and covering the cable. One side of the support plate extends to form a storage part, and the other side has a plurality of infusion holes connected to the storage part. The infusion holes are located at the outlet and are fitted with ball bearings.

[0014] Furthermore, the storage unit is connected to a liquid inlet pipe on its side, and an air pump is also fixed on its side. The air pump is connected to the interior of the storage unit through an air pipe.

[0015] The bridge cable testing device proposed in this utility model has the following advantages: This utility model drives the two traction wheels to rotate, thereby moving the testing frame. Then, by adjusting the height of the two traction wheels through the adjustment component, it can ensure that the traction wheels can press against the cable, preventing the gap between the two traction wheels from being too large or too small, which would result in the inability to clamp the cable or insufficient clamping force. It can effectively improve the adaptability to cables of different diameters. Furthermore, while the testing frame is moving, it can also apply oil to the cable by using ball bearings to press against the cable, thus extending the service life of the cable.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A bridge cable inspection device includes an inspection frame 1, which is composed of a pair of frame bodies 11. The pair of frame bodies 11 are arranged opposite to each other and are hinged and rotated between them and fixed by fasteners 2. A pair of moving devices 3 are fixed inside the frame body 11, and a support plate 4 is provided between the moving devices 3.

[0022] The moving device 3 includes traction wheels 31, and the traction wheels 31 on both sides are used to press against the cable to drive the detection frame 1 to move;

[0023] The frame 11 is provided with an adjustment component 5, which is used to adjust the height of a pair of traction wheels 31. The support plate 4 is provided with a rust prevention mechanism 6 for applying oil to the cable.

[0024] It should be added that the moving device 3 also includes a base for fixing the traction wheel 31. A motor is fixedly installed on the side of the base. The motor is used to drive the traction wheel 31 to rotate. Specifically, the cable is located between the traction wheels 31 on both sides. The traction wheel 31 drives the detection frame 1 to move by pressing against the cable.

[0025] The fastener 2 includes a pair of connecting seats provided on the side of the frame 11, and a locking bolt is provided between the connecting seats. The other end of the locking bolt is threaded with a fixing nut. The pair of frame 11 are fixed by the locking bolt and the fixing nut.

[0026] Furthermore, several cameras are fixedly installed on the side of the testing frame 1. These cameras are electrically connected to the ground monitoring equipment, and the surface condition of the cable is observed and tested through these cameras.

[0027] Furthermore, the adjustment assembly 5 includes a dual-axis motor 51 fixedly mounted on the side of the frame 11, and brackets 52 fixed on both sides of the dual-axis motor 51. The side of the bracket 52 has an extension 521, and a slide block 53 is slidably connected to the extension 521. The shaft end of the dual-axis motor 51 passes through the bracket 52 and is fixedly mounted with a lead screw 54. The lead screw 54 is threadedly connected to the slide block 53.

[0028] Furthermore, it also includes a support rod 55 and a connecting rod 56. The two ends of the support rod 55 are rotatably connected to the base of the traction wheel 31 and the two sides of the slide block 53, respectively. The connecting rod 56 is rotatably connected to the side of the frame 11, and its other end is rotatably connected to the middle of the support rod 55.

[0029] In specific operation, the two shafts of the dual-axis motor 51 drive the lead screw 54 to synchronously drive the slide block 53 to move. While the slide block 53 moves relative to the lead screw, it cooperates with the connecting rod 56 to drive the support rod 55 to rise and fall, thereby adjusting the height of the traction wheel 31.

[0030] Specifically, the extension 521 provides a space for the support rod 55 to move, so that when the support rod 55 is driven, the bottom slides and the top moves accordingly, thereby adjusting the height.

[0031] More specifically, the rust prevention mechanism 6 includes a guide rod 61, the support plate 4 is located above the dual-axis motor 51 and is slidably connected to the frame 11 through the guide rod 61, the other end of the guide rod 61 is fixed with a limit block and a support spring 62 is sleeved on the periphery, and the two ends of the support spring 62 abut against the frame 11 and the support plate 4.

[0032] It is worth mentioning that the support plate 4 plays an auxiliary supporting and guiding role. Under the support of the support spring 62, the support plate 4 has a movable space between itself and the frame 11 to facilitate contact with cables of different diameters. After contact, it is coated with oil for corrosion prevention under the action of the detection frame 1.

[0033] In general, a pair of support plates 4 are arranged opposite each other, and their opposite ends are arc-shaped to close and cover the cable. One side of the support plate 4 extends to form a storage part 63, and the other side is provided with a plurality of infusion holes 64 that communicate with the storage part 63. The infusion holes 64 are located at the outlet and are fitted with ball bearings 65.

[0034] Finally, the storage unit 63 is connected to a liquid inlet pipe on its side, and an air pump 66 is also fixed on its side. The air pump 66 is connected to the inside of the storage unit 63 through an air pipe.

[0035] It should be noted that the specific principle of the ball bearing 65 for oiling is based on the writing principle of a ballpoint pen in the prior art. However, considering that the ball bearing 65 located at the bottom is difficult to oil when it is not under gravity during movement, it is necessary to use the air pump 66 to provide pressure to the inside of the storage section 63 to adapt to the oiling operation of the inclined cable.

[0036] Working method: During operation, lubricating oil is injected into the storage section 63 through the inlet pipe and then the inlet pipe is closed. The height of the two traction wheels 31 is then adjusted according to the diameter of the cable.

[0037] The two shafts of the dual-axis motor 51 drive the lead screw 54 to synchronously drive the slide 53 to move. While the slide 53 moves relative to the other, it cooperates with the connecting rod 56 to drive the support rod 55 to rise and fall, thereby adjusting the height of the traction wheel 31.

[0038] Finally, a pair of frames 11 are placed on both sides of the cable to be tested, and the pair of frames 11 are fixed with fasteners 2 to ensure that the traction wheels 31 on both sides can press against the cable. Then, the test frame 1 is moved by driving the traction wheels 31 with a motor to perform the test. While the test frame 1 is moving, the support plate 4 touches the cable to make the ball bearing 65 rotate and then apply oil to the cable.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
