Description

Technical Field

[0001] This utility model belongs to the technical field of water pipe walking devices, specifically a walking device with a toothed chain. Background Technology

[0002] In the field of water supply pipeline maintenance and inspection, the drive technology of the walking device directly affects the stability and reliability of the equipment in complex pipeline environments. Existing drive solutions generally face technical bottlenecks such as poor environmental adaptability, insufficient power, and high maintenance costs, specifically manifested as follows: 1. Environmental sensitivity and lifespan issues of belt drives 2. Limitations of contact area and geometric adaptability of wheeled drives For traditional wheeled structures, the narrow entrance space to the main water supply pipeline is a fatal obstacle when climbing slopes or curves, provided that the main water supply pipeline cannot be shut off.

[0003] 3. Dynamic and fluid adaptability issues of propeller propulsion systems Some underwater robots borrow the propulsion principle of ship propellers, generating thrust through the rotation of blades. However, such structures present significant problems within enclosed pipes: Low power efficiency: The propeller thrust needs to overcome the resistance of the reverse water flow inside the pipe; Fluid disturbance interference: High-speed rotating blades can disturb the deposits at the bottom of the pipe, severely interfering with the performance of optical inspection equipment.

[0004] The aforementioned technical bottlenecks result in insufficient reliability of existing walking devices in complex pipeline scenarios. Therefore, there is an urgent need to develop new drive devices that combine high traction and long service life. Summary of the Invention

[0005] To solve the above problems, this utility model provides a walking device with a toothed chain.

[0006] This utility model adopts the following technical solution: a chain with pointed teeth, comprising: Multiple alternating inner and outer links, with adjacent inner and outer links hinged by pins; The outer link includes connecting pieces symmetrically arranged on both sides, and traveling teeth are arranged between the connecting pieces on one or both sides.

[0007] In some embodiments, the traveling tooth is a single pointed tooth integrally formed with the outer link.

[0008] In some embodiments, the tip of the cusp tooth is an inclined plane and has a pointed tip, and the width of the root of the cusp tooth is greater than the width of the tip.

[0009] In some embodiments, the walking teeth are multiple multi-pointed teeth integrally formed with the outer link.

[0010] A water pipe traveling device, comprising: The crawler body, and two sets of drive units on both sides of the crawler body, each set of drive units including: The drive sprocket is mounted at the front end of the crawler body via a bearing; The driven sprocket is mounted at the rear end of the crawler body via a bearing; A closed-loop chain is meshed between a drive sprocket and a driven sprocket, wherein the closed-loop chain is the chain with sharp teeth described above; The drive sprocket is connected to the output shaft of the motor via a gear system or directly, and the crawler body is driven to move axially along the pipe by the cyclic rotation of the chain.

[0011] In some embodiments, a lighting device is provided on the crawler body.

[0012] In some embodiments, a camera device is provided on the crawler body.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention integrates a link structure and functional components to form a highly efficient and reliable pipeline movement solution. The inner and outer links achieve a balance between flexible steering and structural reinforcement through a modular hinge design. The traveling teeth utilize a one-piece molding process with a gradually changing cross-section, reducing stress concentration while improving tooth durability. The beveled tooth tip design enhances contact stability with the pipe wall, and together with the adjustable speed transmission system, forms a suitable power transmission mechanism, effectively handling different pipe diameters and operating conditions. The device integrates an optical detection unit, simultaneously recording the surface condition of the pipeline during movement, significantly improving inspection efficiency and safety in confined spaces. Through the synergistic optimization of structural design and functional modules, the entire system achieves technological breakthroughs in mobility reliability, environmental adaptability, and detection integration, providing intelligent support for pipeline maintenance operations.
