Benefits of technology

[0010] This cable crawling obstacle-crossing device attaches a traveling wheel to the cable. A motor drives the traveling wheel to rotate, allowing the device to travel along the cable. Simultaneously, a swingable auxiliary pressure roller presses the cable into the groove of the traveling wheel, preventing it from slipping out and ensuring stability during cable crawling. When crossing an obstacle, the auxiliary pressure roller swings downwards, releasing the pressure on the cable and allowing the traveling wheel to roll directly over the obstacle. Furthermore, the use of an electric push rod to drive the swing of the auxiliary pressure roller ensures accurate repeatability and extends the service life of the drive components. The travel drive motor is housed in a mounting cavity within the cantilever, with both the motor and the electric push rod being built-in, protecting electrical components in complex high-altitude environments. This design also optimizes the structural volume, resulting in a scientifically sound and highly practical design.

Description

Technical Field

[0002] In power systems, as the coverage of high-voltage cables gradually expands, the demand for their maintenance and inspection is also increasing. Current maintenance methods primarily rely on manual high-altitude inspections, which involve the risks of working at height. To reduce these risks, the market is continuously developing inspection equipment capable of automatically crawling along high-voltage cables for inspection.

[0003] The crawling function of the inspection equipment is mainly accomplished by the crawling device at the bottom of the equipment. Since the equipment needs to be erected on the cable for high-altitude operations, it is essential to ensure the stability of the inspection equipment on the cable. Previously, the applicant had applied for a high-voltage cable anti-detachment walking wheel device. The applicant further optimized it and designed this fixed cantilever cable crawling device. The structure of the original crawling device has been further optimized, making it more reasonable and ingenious. By mounting it on the cable inspection equipment, the inspection equipment can easily crawl on the cable and overcome obstacles, improving the stability of the crawling. The design is scientific, reasonable, and highly practical. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] Example 1

[0016] Please see Figure 1-2This application provides a technical solution: a cantilevered fixed cable crawling obstacle-crossing device, which includes a fixed support cantilever 1 for connecting maintenance equipment. The maintenance equipment's outer cover is fixed to the lower end of the fixed support cantilever 1. A traveling wheel 7 is rotatably mounted on the front side of the upper end of the fixed support cantilever 1. A motor mounting cavity 11 is opened at the upper end of the fixed support cantilever 1, and a traveling drive motor 10 for driving the traveling wheel 7 to rotate is installed in the motor mounting cavity 11. Specifically, a U-shaped arm 9 with a downward opening is fixedly mounted on the front side of the motor mounting cavity 11, and a downwardly inclined cable guide rod 8 is fixedly mounted on the front side of the U-shaped arm 9 for guiding the cable into the wheel groove of the traveling wheel 7. At the same time, the traveling wheel 7 is rotatably mounted inside the U-shaped arm 9, and the traveling drive motor 10 is fixedly mounted on the rear side of the U-shaped arm 9, with the output end of the traveling drive motor 10 passing through the U-shaped arm 9 and fixedly connected to the traveling wheel 7.

[0017] Swing arms 5 are rotatably mounted on both sides of the fixed support cantilever 1, located below the traveling wheels 7. An auxiliary pressure roller 6 is rotatably mounted at the end of each swing arm 5. The swing arms 5 can drive the auxiliary pressure roller 6 to rotate below the traveling wheels 7. An electric push rod 2 for driving the rotation of the swing arms 5 is installed inside the fixed support cantilever 1. Specifically, as shown... Figure 1 as well as Figure 2 As shown, the electric actuator 2 is located inside the fixed support cantilever 1. The bottom of the electric actuator 2 is rotatably connected to the inner wall of the fixed support cantilever 1. An arc-shaped connecting arm 3 is rotatably connected to the output end of the electric actuator 2. A rotating shaft 4 is rotatably installed in the fixed support cantilever 1. Both ends of the rotating shaft 4 pass through the fixed support cantilever 1 and are fixedly connected to the swing arms 5 on both sides. Figure 2 As shown, bearings 12 are provided on both sides of the fixed support cantilever 1 to enable the installation of the rotating shaft 4 on the fixed support cantilever 1, while the upper end of the arc-shaped connecting arm 3 is fixedly connected to the rotating shaft 4. By driving the arc-shaped connecting arm 3 to move through the electric push rod 2, the rotating shaft 4 can be driven to rotate, thereby realizing the swing of the swing arm 5.

[0018] In practical applications, after the traveling wheel 7 is placed on the cable, the electric push rod 2 drives the swing arm 5 to swing, causing the auxiliary pressure wheel 6 to swing to the underside of the cable, pressing the cable into the groove of the traveling wheel 7, thus preventing the cable from coming out of the groove. When it is necessary to cross an obstacle on the cable, the electric push rod 2 drives the swing arm 5 to swing downward, causing the auxiliary pressure wheel 6 to release the pressure on the cable, allowing the traveling wheel 7 to roll over the obstacle. After crossing the obstacle, the auxiliary pressure wheel 6 is pressed onto the cable again, enabling the device to crawl stably on the cable.
