Description

Technical Field

[0001] This invention belongs to the field of robotics, and more specifically, relates to a device and method for maintaining the PE material on the surface of cable-stayed bridge cables. Background Technology

[0002] With sustained economic growth and the accelerating construction of transportation infrastructure, long-span bridges have experienced rapid development. Cable-stayed bridges, as a new type of modern bridge, are widely used globally due to their adaptability and economic efficiency. As a key load-bearing component of cable-stayed bridges, the service safety of the cables is a major concern. After bridge construction, the cables are exposed to the atmosphere for extended periods, causing the polyethylene (PE) protective layer on their surface to gradually harden, age, and crack. Once the PE layer fails, the high-strength steel wires inside will be directly exposed to moisture and acidic media, leading to corrosion and even wire breakage, resulting in a decrease in cable strength and ultimately threatening the overall safety of the bridge. Therefore, developing an effective cable surface maintenance device and method is of great significance for ensuring the safe operation of cable-stayed bridges and extending the service life of the cables.

[0003] Currently, there has been some research and application of technologies related to the surface maintenance of cable-stayed bridges. Among existing technologies, patent document 202210696632.0 provides a surface grinding and maintenance device for cable-stayed bridges, comprising: an arc-shaped motion platform, a grinding and spraying module, and a camera monitoring module. The arc-shaped motion platform includes: an arc-shaped guide rail, an arc-shaped gear, and a connecting rod. The grinding and spraying module includes: a rotating platform, a spraying mechanism, and a grinding mechanism. The rotating platform includes: a guide wheel, a moving plate, a rotary drive motor, and a rotary drive gear. The spraying mechanism includes: a paint fixing frame, a paint extrusion push rod, and a paint tank. The grinding mechanism includes: a grinding feed drive motor, a reducer, a slide base, a slider, a Z-shaped bracket, a grinding drive motor, a limit switch, a dust cover, a dust extraction fan, a dust filter cover, and a wire brush. The camera monitoring module includes: an L-shaped bracket, a camera fixing bracket, and a camera. Through the coordinated work of these modules, it can serve as equipment for surface grinding and maintenance of cable-stayed bridges, solving to some extent the problem of low automation in surface grinding and maintenance of cable-stayed bridges.

[0004] In the prior art, patent document CN117125165A also provides an adaptive cable inspection robot, a cable surface defect detection system, and a method. The adaptive cable inspection robot includes multiple structural units; each structural unit includes a support body, a crawling drive component, and an adaptive adjustment component; the crawling wheels of all structural units are in close contact with the cable to be inspected, and the crawling drive motor is used to drive the crawling wheels to rotate, thereby enabling the inspection robot to move along the cable to detect cable surface defects. The adaptive cable inspection robot can move along the cable and has high stability. The cable surface defect detection system can complete in-situ detection of cable surface defects with high detection efficiency. The detection method can receive information through a ground terminal, model the cable according to the running path, and mark the defect location, which facilitates subsequent maintenance personnel to quickly repair cable defects.

[0005] In summary, existing technologies can detect, mark, and polish cable surface defects, but they still have the following shortcomings: (1) Insufficient repair depth: The polishing and spraying scheme can only deal with shallow damage. For severe damage such as deep cracking or local peeling of the PE protective layer, it cannot restore the structural integrity, and the internal steel wires are still exposed to corrosion risks; (2) Material compatibility and durability defects: The bonding strength between the sprayed material and the original PE layer is low, and it is easy to peel off again due to environmental stress. Moreover, the anti-aging performance of the new coating is difficult to match the design life of the original protective layer; (3) Single function: The detection robot only provides defect location and requires additional manual intervention for repair. However, the existing repair device lacks an active repair mechanism that is adapted to the depth of damage; (4) Low maintenance efficiency: Existing technologies rely on step-by-step operations and have a low degree of automation and closed loop, making it particularly difficult to deal with large-scale continuous damage to high-altitude cables.

[0075] The rotating motor 303 operates, driving the pulley 305 to rotate. Because the pulley 305 meshes with the synchronous belt 403 of the rotating guide rail 4, the rotating platform 302 and related components rotate along the rotating guide rail 4. The V-shaped wheel 308 fits against the inner circular protrusion of the annular guide rail, and the auxiliary wheel 309 provides additional support, ensuring smooth rotation. The quick-release guide rail 301 is used to connect with the winding translational assembly and adapt to different scenarios.

The quick-release design facilitates assembly with other components and adapts to different operational needs.

[0076] like Figure 8As shown, the rotating guide rail includes an annular guide rail 401, an annular guide rail notch 402, and a timing belt 403. The annular guide rail 401 and the annular guide rail notch 402 have multiple circular protrusions on their inner sides; in this embodiment, there are two. The annular guide rail 401 and the annular guide rail notch 402 can be assembled into a complete ring. The timing belt 403 is fixedly connected to the middle of the outer side of the annular guide rail 401 and the annular guide rail notch 402. Further, the plurality of V-shaped wheels 308 are respectively attached to the circular protrusions on the inner sides of the annular guide rail 401 and the annular guide rail notch 402; the pulley 305 meshes with the timing belt 403; and the auxiliary wheel 309 is correspondingly attached to the top of the annular guide rail 401 and the annular guide rail notch 402. The rotating guide rail is composed of annular guide rail 401 and annular guide rail notch 402, forming a complete ring. The inner circular protrusion allows the V-shaped wheel 308 of the winding rotating component to engage, while the outer synchronous belt 403 meshes with the rotating component pulley 305, providing a rotational track and transmission for the rotating component. This assembly provides a stable and continuous annular rotating track, ensuring reliable and smooth rotation of the winding rotating component, enabling the winding operation to cover the entire circumference of the cable. The splicing design facilitates installation, maintenance, and adaptation to different scenarios, enhancing the overall practicality of the device.

[0077] like Figure 7 As shown, the rotating guide rail bracket includes a first guide rail bracket (501) and a second guide rail bracket (502). In this embodiment, the joint between the annular guide rail 401 and the annular guide rail notch 402 corresponds to the top of the first guide rail bracket (501). The first guide rail bracket (501) and the second guide rail bracket (502) support the rotating guide rail 4, keeping it at a suitable height and position, ensuring the installation stability of the entire device. The joint of the annular guide rail corresponds to the top of the first guide rail bracket, providing coordinated support.

[0078] This component can stably support the rotating guide rail, ensuring the stable installation of the rotating guide rail and the winding rotating component, providing a reliable foundation support for the entire maintenance device, and ensuring the stability and reliability of the components when working together.

[0079] like Figure 9 As shown, the specific working process and principle of cable surface maintenance using this embodiment of the invention are as follows:

[0080] S100: Install the wound cable surface maintenance device on the cable requiring repair. Install the first guide rail bracket (501) and the second guide rail bracket (502) on the climbing device, and install the annular guide rail 401 on it. Adjust the rotating motor bracket 304 so that the inner V-shaped wheel 308 of the winding rotating assembly is engaged with the circular protrusion on the inner side of the annular guide rail 401, and the outer pulley 305 is firmly and stably engaged with the synchronous belt 403. Install the annular guide rail notch 402 to form a complete ring. Adjust the fastening holes of the quick-release platform 114 and the quick-release guide rail 301 according to the cable size to accommodate the cable size.

[0081] S200: Install the tape and set the mechanism to its initial state. Install the tape body onto the tape roller 208, stretch the tape end so that it passes through the auxiliary roller 209, the pressure roller 205, and the sliding roller 202, and is clamped between the lever bracket 201 and the tape clamp 203. In the initial state, the axial moving platform 107 is at the bottom of its stroke, and the radial moving platform 112 is at the outermost point of its stroke.

[0082] S300: Initial bonding. The climbing device moves to the position requiring repair, and the radial moving platform 112 moves inward, bringing the clamping roller 205 into contact with the cable. The radial moving platform 112 moves further, at which point the clamping roller 205 slowly rolls along the cable wall, while the sliding roller 202 gradually approaches the cable wall and finally presses against it. During this process, the end of the tape clamped between the lever bracket 201 and the tape clamp 203 is automatically released, completing the initial bonding motion.

[0083] S400: Repair is performed. After the tape is applied, the winding rotating assembly rotates under the drive of the rotating motor 303, while the axial moving platform 107 is lifted under the drive of the axial screw motor 101. The two work together to complete the tape winding.

[0084] S500: Mechanism restoration. After all the tape is wrapped, the axial moving platform 107 and the radial moving platform 112 return to their initial positions, completing the repair task.

[0085] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
