Description

Technical Field

[0001] This utility model belongs to the field of tunnel inspection robot technology, specifically relating to a charging device for a side-mounted tunnel inspection robot. Background Technology

[0002] In recent years, tunnel inspection robots have been increasingly applied to tunnel safety inspections, replacing manual labor to achieve fully automated inspections around the clock. These robots utilize various sensors, including high-definition cameras, infrared cameras, and gas sensors, to monitor traffic conditions inside the tunnel, detect defects such as water seepage, fireproofing layer peeling, and cracks on the tunnel walls, and inspect for road obstacles. Therefore, ensuring the robot can quickly and stably complete its charging process is a crucial indicator of its efficient operation.

[0003] Currently, the two most common charging methods for tunnel robots are wireless charging and contact charging. Existing tunnel inspection robots mostly move on I-shaped tracks and are mostly suspended structures. The tracks are fixed to the tunnel wall by upper supports. Therefore, contact charging devices are mostly set above the tracks, making it impossible to install cameras on the robots above the tracks, resulting in a large blind spot. At the same time, it cannot meet the charging requirements of side-mounted track robots.

[0004] Conventional wireless charging requires a larger power adapter and a larger electromagnetic induction coil when charging at high power, which significantly increases the size and weight of the robot and greatly restricts the miniaturization of track inspection robots. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a charging device for a side-mounted tunnel inspection robot, which does not affect the top mounting space of the robot.

[0006] The technical solution adopted in this utility model is: A charging device for a tunnel inspection robot includes a charging box disposed on the side of a track, and a charging trigger switch and a positioning module disposed on the left and right sides of the charging box, respectively. The charging box includes a box body and a support. The box body is fixedly connected to one end of the support, and the other end of the support is fixedly connected to the side of the track.

[0007] Furthermore, the housing includes a main frame, a charging brush plate disposed on the lower outer side of the main frame, and a limit switch disposed on the upper part of the main frame. A charging brush block and a charging trigger block are correspondingly disposed on the side of the robot.

[0008] Furthermore, an isolation cover is provided inside the main frame. The isolation cover has an opening on one side, and a flange is provided at the opening. The flange is fixedly connected to the mounting hole opened on the main frame. The limit switch is set inside the isolation cover. A waterproof connector is provided on the side of the isolation cover. The cable of the limit switch passes through the waterproof connector and enters the charging box.

[0009] Furthermore, the main frame is equipped with a power adapter and a charging control module, with indicator lights on its side and a power switch and power connector installed on its bottom.

[0010] Furthermore, the charging trigger switch includes a base fixedly connected to the track and a trigger baffle disposed on the base. The two ends of the trigger baffle are inclined outward. A robot charging switch is provided on the side of the robot. The robot charging switch is provided with a cylindrical connection contact, which is used to cooperate with the trigger baffle.

[0011] Furthermore, an elongated hole is provided on the base, and a mounting hole is provided on the trigger baffle for mating with the elongated hole.

[0012] Furthermore, the positioning module includes a tag holder and an RFID positioning tag mounted on the tag holder, and a robot positioning module corresponding to the RFID positioning tag is provided on the side of the robot.

[0013] Furthermore, a positioning baffle is provided on the label holder.

[0014] Furthermore, the charging box, charging trigger switch, and positioning module are located on the same side of the track and on the opposite side of the robot.

[0015] The positive effects of this utility model are: The charging box of this invention is located on the side of the track, avoiding the vertical direction of the track, allowing cameras to be installed on both sides of the inspection robot to provide a comprehensive shooting perspective. Furthermore, it is also suitable for side-mounted inspection robots. A charging trigger switch and a positioning module are also provided on the side of the track. The charging control module can simultaneously achieve automatic power-on and power-off of both the robot and the charging device. Attached Figure Description
