[0001] This utility model relates to the field of small-diameter pipeline robot inspection technology, specifically a spiral-driven walking and protection mechanism for small-diameter pipeline robots. Background Technology

[0002] Mobile robots are currently the most widely used type of robot. Their main function is to replace humans in performing dangerous, complex, or high-intensity work. The robot's locomotion mechanism is an important component of mobile robots.

[0003] Current small-diameter pipeline robots inevitably experience vibrations during movement, which may damage the top inspection mechanism and its internal components. In addition, the vibrations and wear generated during movement may reduce the lifespan of the small-diameter pipeline robot. Its internal circuits and electronic components may malfunction due to vibrations. Furthermore, most of the inspection mechanisms are exposed for extended periods and cannot be stored, which also reduces the efficiency of the small-diameter pipeline robot in pipeline inspection. Therefore, a spiral-driven walking protection mechanism for small-diameter pipeline robots is needed to improve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-4 The spiral-driven small-diameter pipe robot walking protection mechanism shown includes a mobile walking component 1, a shock-absorbing component 2 is provided on the top of the mobile walking component 1, and a lifting protection component 3 is provided inside the shock-absorbing component 2.

[0026] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 3As shown, the shock absorption assembly 2 includes a carrier box 201. A damping rod 202 is fixedly connected to the bottom of the carrier box 201, and a shock-absorbing spring 203 is elastically connected to the bottom of the damping rod 202. A rectangular groove 204 is provided inside the carrier box 201. The lifting and protection assembly 3 includes a detection body 301. A top extension rod 306 is installed inside the carrier box 201. The output end of the top extension rod 306 is fixedly connected to the detection body 301. A slide rail 302 is fixedly connected to the side of the carrier box 201, and a slider 303 is slidably connected to the side of the slide rail 302. The shock absorption mechanism composed of the damping rod 202 and the shock-absorbing spring 203 effectively reduces the vibration generated by the small-diameter pipe robot during its movement, avoiding damage to the detection body and its accessories caused by excessive vibration, as well as the malfunction of internal components of the small-diameter pipe robot. This ensures stable movement while also protecting the entire detection and walking mechanism.

[0027] The system includes two slide rails 302 and two sliders 303. The detection body 301 is fixedly connected to the slider 303. A sampling head 305 is installed on the side of the detection body 301, and two lighting lamps 304 are fixedly connected to the side of the detection body 301. The extension rod 306 extends the detection body 301, and the slider 303 slides on the slide rail 302. This controls the lifting height of the detection body 301, improves the stability of the lifting, and allows the detection body 301 to be stored in the carrier box 201, ensuring that the detection body 301 is not corroded by dust and moisture, thereby extending the service life of the detection body 301.

[0028] In this embodiment, reference is made to Figure 1 and Figure 4 As shown, the mobile walking assembly 1 includes a base frame 101. A mounting box 102 is fixedly connected inside the base frame 101. A motor 103 is installed inside the mounting box 102. A transmission wheel 104 is fixedly connected to the output end of the motor 103. A bearing seat 109 is fixedly connected inside the base frame 101. A belt 105 is provided on the side of the transmission wheel 104. A rotating wheel 106 is provided inside the belt 105. A rotating rod 107 is fixedly connected inside the rotating wheel 106 and extends into the bearing seat 109. The rotating rod 107 is provided with a movable wheel 108 on its side, and the rotating rod 107 extends into the interior of the movable wheel 108. There are two movable wheels 108. A connecting rod 110 is fixedly connected to the side of the base frame 101. A following wheel 111 is provided on the side of the connecting rod 110. There are two connecting rods 110 and following wheels 111. By using the drive of the motor 103, the transmission mechanism composed of the transmission wheel 104, belt 105 and rotating wheel 106 is driven to improve the walking efficiency and inspection benefits of the small-diameter pipeline robot.

[0029] In this solution, a spiral-driven small-diameter pipeline robot walking and protection mechanism is used. The motor 103 drives a transmission mechanism consisting of a transmission wheel 104, a belt 105, and a rotating wheel 106, which in turn rotates the rotating rod 107. This allows the moving wheel 108 to move the entire device. During movement, a damping mechanism consisting of a damping rod 202 and a shock-absorbing spring 203 effectively reduces vibrations generated by the small-diameter pipeline robot, thus protecting the entire walking mechanism. The extension rod 306 extends and retracts the detection body 301, and the slider 303 slides on the slide rail 302, controlling the height of the detection body 301 for easy storage. This also allows control of the height of the sampling head 305, making it suitable for inspecting pipelines of different specifications.
