Description

Technical Field

[0002] As a critical load-bearing component, bridge cables may be affected by corrosion, fatigue damage, and other factors during long-term use, leading to a decline in their structural performance and potentially jeopardizing the safe operation of the bridge in severe cases. However, traditional inspection methods often rely on manual visual inspection or simple tool-assisted checks. These methods are not only inefficient but also fail to provide a comprehensive and detailed inspection of the cables, especially for cable sections located at heights or inaccessible areas. Furthermore, manual inspection carries certain safety risks and is difficult to implement effectively under complex environmental conditions (such as strong winds or severe weather).

Detailed Implementation

[0020] like Figure 1-5 As shown, a bridge cable inspection device includes two sets of drive frames 4 on the frame 1. Driven wheels 5 and drive wheels 3 are provided at the upper and lower ends of the drive frames 4. A climbing motor 9 is also provided on the drive frames 4. The climbing motor 9 is connected to the drive wheels 3. The two sets of drive frames 4 are slidably connected to the frame 1. A tightening motor 2 is provided on one side of the frame 1. An adjusting screw 14 is provided on the tightening motor 2. The adjusting screw 14 is threadedly connected to the two sets of drive frames 4. The adjusting screw 14 has two sections of thread with opposite directions of rotation. An inspection camera 6 is also provided on the frame 1.

[0021] The tightening motor 2 is activated to drive the adjusting screw 14. Since the adjusting screw 14 has two sections of threads with opposite directions, the two sets of drive frames 4 connected to it can move relative to each other, thereby clamping the bridge cable. Then, the climbing motor 9 is activated. This motor is connected to the drive wheel 3, which begins to rotate and drives the entire frame 1 to crawl along the bridge cable. During the crawling process, the inspection camera 6 mounted on the frame 1 takes pictures of the bridge cable surface for subsequent analysis to determine if the cable is damaged.

[0022] In the preferred embodiment, two sets of drive frames 4 are symmetrically arranged on the frame 1. The frame 1 is provided with multiple guide rails 15, and the drive frame 4 is provided with sliders 16, which are slidably connected to the guide rails 15.

[0023] The tightening motor 2 drives the adjusting screw 14. Since the adjusting screw 14 has two sections of threads with opposite directions, it can cause the two sets of symmetrically arranged drive frames 4 to slide relative to each other along the guide rail 15 on the frame 1 through the slider 16 on them, thereby achieving effective clamping of bridge cables of different diameters.

[0024] The drive frame 4 is symmetrically arranged and slidably connected to the guide rail 15 via the slider 16, which makes the device more stable when clamping the cable and adaptable to cables of different sizes. The design of the guide rail 15 and the slider 16 improves the smoothness of the movement of the drive frame 4 and ensures the device crawls smoothly on the cable.

[0025] In the preferred embodiment, each of the two sets of drive frames 4 is provided with a nut block 17, and the two sections of the adjusting screw 14 with opposite rotation directions are respectively threaded to the nut blocks 17 on the two sets of drive frames 4, and the adjusting screw 14 drives the two sets of drive frames 4 to move relative to each other.

[0026] By adjusting the design of the screw 14 and the nut block 17, the two sets of drive frames 4 can move relative to each other, ensuring a stable clamping of bridge cables of different diameters.

[0027] In the preferred embodiment, a mounting plate 7 is also provided at one end of the frame 1, and the detection camera 6 is mounted at the end of the mounting plate 7. The mounting plate 7 provides a stable mounting platform for the detection camera 6, ensuring the stability of the camera during the equipment crawling process and helping to improve the quality of the captured images.

[0028] In the preferred embodiment, the other end of the frame 1 is provided with an adjustment mounting bracket 11, the outer surface of the adjustment mounting bracket 11 is provided with an electric push rod 10, the end of the electric push rod 10 is provided with an adjustment wheel 13, the axis of the adjustment wheel 13 is set parallel to the axis of the cable being measured, and one side of the adjustment wheel 13 is connected to the position adjustment motor 12.

[0029] When it is necessary to adjust the position of the inspection camera 6 to another surface of the bridge cable, the electric push rod 10 is activated, pushing the adjusting wheel 13 at its end closer to the surface of the bridge cable. At this time, the position adjustment motor 12 drives the adjusting wheel 13 to rotate. Since the axis of the adjusting wheel 13 is parallel to the axis of the cable being tested, this will cause the frame 1 to rotate on the bridge cable, so as to adjust the position of the inspection camera 6. It is worth noting that when the frame 1 is stationary, the adjusting wheel 13 alone cannot drive the frame 1 to rotate on the bridge cable; only when the driven wheel 5 and the driving wheel 3 move on the bridge cable can the adjusting wheel 13 effectively drive the entire frame 1 to rotate, thereby ensuring that the inspection camera 6 can capture images of the bridge cable surface in all directions.

[0030] The design of electric push rod 10 and adjusting wheel 13 enables the adjustment of the position of frame 1 relative to the cable, facilitating all-round imaging of the bridge cable surface; the addition of position adjustment motor 12 makes the adjustment process more flexible and accurate, which helps to improve detection efficiency and quality.

[0031] In the preferred embodiment, the adjusting wheel 13 is mounted on the wheel frame 1301, which is connected to the telescopic end of the electric push rod 10. The position adjusting motor 12 is mounted on the wheel frame 1301, and its output end is connected to the adjusting wheel 13. The position adjusting motor 12 drives the adjusting wheel 13 to rotate, causing the frame 1 to rotate on the bridge cable, thereby adjusting the position of the detection camera 6.

[0032] The design of the electric push rod 10 and the wheel frame 1301 enables the adjustment of the position of the frame 1 relative to the cable by the adjusting wheel 13, which facilitates all-round imaging of the bridge cable surface. The position adjustment motor 12 is set on the wheel frame 1301 and directly drives the adjusting wheel 13, making the adjustment process more flexible and accurate, which helps to improve the detection efficiency and quality.

[0033] In the preferred embodiment, the rack 1 is also equipped with a control box 8, which contains a battery, a control module, and a wireless receiving module. It is also equipped with a wireless remote control, which is connected to the control module through the wireless receiving module.

[0034] Commands are sent via a wireless remote control to a wireless receiving module inside the control box 8, which then interprets these commands to operate the equipment. The tightening motor 2 is activated via the wireless remote control, driving the adjusting screw 14 to rotate. This causes the two sets of drive frames 4, each with a nut block 17, to move relative to each other along the adjusting screw 14, effectively clamping the bridge cables. Similarly, the electric push rod 10, the position adjusting motor 12, and the climbing motor 9 can be remotely controlled to adjust the attitude and movement of the frame 1, and to capture images via the detection camera 6. The control box 8 contains a battery that provides the necessary power to the entire device, ensuring all components function properly.

[0035] In the preferred embodiment, the end of the climbing motor 9 is connected to the drive wheel 3 via a gearbox, which is mounted on the drive frame 4. Connecting the climbing motor 9 and the drive wheel 3 via the gearbox enables efficient power transmission, ensuring stable movement of the equipment on the cable. The gearbox design optimizes torque output, improving the equipment's ability to cope with different working environments.

[0036] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
