Technical Field
[0001] This invention belongs to the field of rope-climbing robot technology, specifically relating to a inchworm-inspired rope-climbing robot. Background Technology
[0002] Rope-climbing robots are a type of robot capable of moving autonomously on ropes. By moving freely on the ropes, they can perform maintenance. Mine fishing boxes are components in mine hoisting devices that wind up and store vertical steel cables. In the mineral mining process, steel cable winches are mainly used to control the lifting of workers and goods at the bottom of the mine, playing a crucial role in the safe mining of minerals.
[0003] To ensure the safety of mineral mining, the rapidly wearing vertical steel cables inside the mine fishing box require regular inspection and maintenance. However, due to the limited space inside the mine fishing box, inspection is difficult. Traditional rope-climbing robots rely heavily on manual placement and movement. Furthermore, their limited functionality makes it difficult to achieve human-machine collaboration in maintenance. This results in significant limitations and blind spots in the use of traditional rope-climbing robots, hindering effective inspection of the vertical steel cables inside the mine fishing box and creating substantial safety hazards during their use.
[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an inchworm-like rope-climbing robot. Summary of the Invention

[0053] refer to Figures 4-5 As shown, a rotating connecting seat 205 is rotatably connected within the steering wheel assembly frame 204. The rotating connecting seat 205 serves as an assembly limit for the steering wheel 202. Simultaneously, it facilitates the deflection of the steering wheel 202 by controlling the rotation of the rotating connecting seat 205, thereby allowing the rope-climbing robot to detach from the rope as the steering wheel 202 deflects, providing a foundation for subsequent single-rope obstacle crossing and rope changing.

[0084] In addition, the inchworm-like rope-climbing robot uses continuous PID control of angle and speed in an STM32 microcontroller, and uses ant colony algorithm and annealing algorithm to optimize the motion path of the inchworm-like rope-climbing robot, making rope changing more efficient and stable.
[0085] refer to Figure 1 As shown, when using the inchworm-like rope-climbing robot for dual-rope inspection, the inspection module is mounted on the module chuck 101. The power wheel 203 and the steering wheel 202 work together to clamp the steel cable to be inspected, thus fixing the inchworm-like rope-climbing robot between the two cables. Subsequently, according to the robot's operational needs, the power wheel 203 is driven to rotate by controlling the high-speed motor 219 or the high-torque motor 223, allowing the robot to crawl along the steel cable. The inspection module moves along the steel cable to perform the inspection.
[0086] refer to Figures 11-12 As shown, when a rope needs to be replaced during a dual-rope inspection, the operation of the drive wheel 203 is paused. Then, by controlling the operation of the telescopic motor 218, the telescopic arm 212 is extended or retracted, causing the single drive wheel 203 to detach from the steel cable. Furthermore, by controlling the operation of the deflection motor 211, the steering wheel 202 deflects under the combined action of the deflection worm gear 209 and the deflection worm 210, causing the steering wheel 202 to detach from the steel cable. Finally, by controlling the operation of the drive bevel gear 307, the connecting arm 301 swings under the combined action of the swing worm gear 312 and the swing worm wheel 311. The swinging of the connecting arm 301 swings a set of climbing rope inspection mechanisms 2 onto another steel cable. Subsequently, by controlling the operation of the telescopic motor 218 and the deflection motor 211, the set of climbing rope inspection mechanisms 2 is reassembled onto the other steel cable, thus completing the rope replacement operation.
[0087] refer to Figures 13-14 As shown, when using the inchworm-like rope-climbing robot for single-rope inspection, the robot is mounted on a single steel cable through the cooperation of a rope-climbing inspection mechanism 2 and a swing-arm linkage mechanism 3. The power wheel 203 is rotated by controlling the high-speed motor 219 or the high-torque motor 223, and the inspection module moves along the single steel cable with the module chuck 101 to perform the inspection.
[0088] refer to Figures 13-14As shown, when obstacle crossing is required during single-rope inspection, the rope-climbing inspection mechanism 2 can be detached from the steel cable by controlling the extension and retraction of the telescopic arm 212, the deflection of the steering wheel 202, and the swinging of the connecting arm 301. Then, by continuing to control the rotation of the power wheel 203, the inchworm-like rope-climbing robot can climb on the single steel cable. Subsequently, by controlling the swinging of the connecting arm 301, the deflection of the steering wheel 202, and the extension and retraction of the telescopic arm 212, the rope-climbing inspection mechanism 2 can re-grip the steel cable, completing the obstacle crossing for one group of rope-climbing inspection mechanisms 2. Then, the same operation is used to perform obstacle crossing operations on another group of rope-climbing inspection mechanisms 2. After obstacle crossing, single-rope inspection can continue.
[0089] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0090] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
