Description

Technical Field

[0001] This utility model relates to the field of power distribution line maintenance technology, specifically a subway power distribution line maintenance device. Background Technology

[0002] To ensure the safety of the subway's power supply, power transmission lines are usually erected at high places on the top of the tunnel where they are not easily accessible. Due to environmental factors or the aging of the power lines themselves, regular routine maintenance of the lines is required.

[0003] Current line maintenance devices, such as the one announced in CN215756277U, are a type of transmission line maintenance device. The device body includes a lifting component and a placement component. The lifting component houses the placement component. Through the lifting component, workers can maintain the transmission line at different positions or heights during maintenance.

[0004] However, because the subway line is located high in the tunnel, the process of maintaining it manually using mobile lifting components is cumbersome, time-consuming, and labor-intensive. Therefore, we have proposed a subway power distribution line maintenance device to solve the problems mentioned above. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

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

[0022] Please see Figure 1-4 This utility model provides an embodiment of a subway power distribution line maintenance device, including a subway power distribution cable tray 1. Bolt through holes 2 are provided inside both ends of the subway power distribution cable tray 1. Bundled cables 3 are installed inside the subway power distribution cable tray 1, and the bundled cables 3 are fixedly connected to the subway power distribution cable tray 1 by clamps 6 and bolts. C-shaped guide frames 4 are provided on both sides of the subway power distribution cable tray 1, and the C-shaped guide frames 4 are integrally formed with the subway power distribution cable tray 1. A mobile maintenance mechanism 5 is installed below the subway power distribution cable tray 1. The mobile maintenance mechanism 5 includes a housing 501, a base 502 installed at the lower end of the housing 501, and brackets 506 installed on both sides below the front end of the base 502. The lower ends of the brackets 506 extend into the slots of the C-shaped guide frames 4, and driven wheels 507 are installed on the outer sides of the brackets 506. The lower ends of the base 502 are also provided on both sides below the rear end. A transmission cover 504 is installed, the lower end of which extends into the slot of the C-shaped guide frame 4. A drive wheel 505 is installed on the outer side of the transmission cover 504. A microcontroller chip, a GPS positioning module, a power module, a wireless data transmission module, and a motor are installed inside the housing 501. There are two motors, and the output ends of the two motors extend into the inside of the two transmission covers 504 respectively. They are connected to the drive wheel 505 through a belt drive mechanism. The microcontroller chip is bidirectionally electrically connected to the terminal through the wireless data transmission module. A line detection head 510 is installed on the bottom surface of the base 502. The line detection head 510 includes a camera 5101, an infrared temperature measuring head 5102 arranged around the camera 5101, and an illumination lamp 5103 arranged in front of the camera 5101. The output end of the line detection head 510 is electrically connected to the input end of the microcontroller chip.

[0023] The subway power distribution cable tray 1 is suspended at the top of the tunnel and fixed to the tunnel base through bolt through holes 2 at the ends and expansion bolts. Multiple subway power distribution cable trays 1 are connected end to end. During maintenance, the mobile maintenance mechanism 5 is activated. The microcontroller chip in the mobile maintenance mechanism 5 drives the motor group to run. Under the action of belt transmission, it drives two sets of drive wheels 505 to move, so that it moves along the direction of the subway power distribution cable tray 1 by relying on the C-shaped guide frame 4. During the movement, the line detection head 510 located at the lower end of the mobile maintenance mechanism 5 can detect the appearance and temperature information of the cable through the camera 5101 and the infrared thermometer 5102.

The output end of the power module is electrically connected to the input end of the microcontroller chip. A charging station is set at the end of the subway power distribution bridge 1 to charge the mobile maintenance mechanism 5 after it has been inspected, so that it can be used again next time.

Laser sensors 509 are installed on the connecting arms 508 at an angle toward the C-shaped guide frame 4. During the movement of the mobile maintenance mechanism 5, the laser sensors 509 can detect the condition of the front C-shaped guide frame 4 in advance. When a damaged section appears in the C-shaped guide frame 4, the laser sensors 509 can promptly send a signal to the microcontroller chip due to the change in detection distance, stopping the mobile maintenance mechanism 5 from continuing to move, so as to ensure its safety.
