Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a pipeline creeping anti-skid driving device. Background Art

[0002] With the continuous improvement and development of urban infrastructure, the pipeline system, as an important part of the city, its safety and stability are crucial to the normal operation of the city. However, since pipelines are usually located underground or in places that are difficult to observe directly, inspection, maintenance and cleaning are often very difficult. Therefore, the development of a device that can move stably and efficiently inside the pipeline has become an urgent technical need. The environment inside the pipeline is usually more complex, including different pipe diameters, materials, curvatures, possible water accumulation, obstacles, etc. This requires the pipeline crawling device to have a strong driving force and obstacle crossing ability to cope with various complex environments. At the same time, the anti-slip function is also crucial to ensure that the device does not slip or lose control during the crawling process. In order to meet these needs, the pipeline crawling anti-slip drive device came into being.

[0003] Publication number "CN208997561U" provides a crawler for inspecting the inner wall of a pipeline, which can be embedded in the inner cavity of the pipeline to be inspected, and includes: a main frame, on which a mounting portion for installing a detection instrument is provided; a crawler wheel provided at the bottom of the main frame; an adsorption magnet provided in the main frame, which is used to adsorb the main frame on the inner wall of the pipeline so that the crawler wheel is pressed against the inner wall of the pipeline; a fixed shaft for providing driving force for the active wheel in the crawler wheel; and a power storage device provided in the main frame and connected to the fixed shaft. The crawler can crawl on the inner wall of the pipeline, and after the corresponding detection instrument is installed on the crawler, the inner wall of the pipeline can be detected, thereby ensuring the safety of the pipeline.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] The diameters of pipes are often different. For the above-mentioned equipment, pipes of different diameters often require crawlers of different sizes to adapt, which is time-consuming, labor-intensive and consumes a lot of resources. In addition, during the crawling process of the crawler, the dust accumulated on the inner wall of the pipe may affect the crawler, reducing the friction between the tire and the inner wall of the pipe, causing the tire to slip, affecting the use of the device.

[0034] A cleaning component is arranged on the connecting rod 4 and is used for cleaning dust on the inner wall of the pipeline.

[0035] Embodiment 2:

[0036] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the telescopic assembly, the telescopic assembly includes a fixed shaft 7 fixedly arranged on the fixed base 1, a rotating plate 8 is rotatably arranged on the fixed shaft 7, the rotating plate 8 is rotatably connected to the moving block 3 through a rotating rod 9, the rotating rod 9 is set in an "L" shape, and a connecting block 10 is fixedly arranged at the bottom of the two relatively arranged moving blocks 3, and an electric telescopic rod 11 is fixedly arranged between the connecting blocks 10;

[0037] In this embodiment, the fixed shaft 7 plays the role of supporting and fixing the rotating plate 8. The rotating plate 8 can be rotated, thereby driving the rotating rod 9 to rotate, and the moving block 3 is driven to move under the action of the movable groove 2.

[0038] Embodiment three:

[0039] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the cleaning assembly, the cleaning assembly includes a support plate 12 fixedly arranged on the connecting rod 4, a fixed plate 13 is fixedly arranged on the support plate 12, a plurality of spring telescopic rods 14 are fixedly arranged on one side of the fixed plate 13 at equal distances, a cleaning scraper 15 is fixedly arranged on one side of the spring telescopic rod 14, the cleaning scraper 15 is fixedly connected to the mounting rod 5 through a plurality of support rods 16, inclined surfaces 18 are fixedly arranged on both sides of the cleaning scraper 15, and a cleaning baffle 20 is fixedly arranged on the cleaning scraper 15;

The support rod 16 plays a supporting role. At the same time, the support rod 16 is made of elastic material, which can make the cleaning scraper 15 fit more closely to the inner wall of the pipe, further improving the cleaning efficiency. The setting of the inclined surface 18 can make the scraped dust slide to both sides along the inclined surface 18, so as not to affect the electric wheel 6. The cleaning baffle 20 will also block the scraped dust, further improving the anti-slip effect of the device.

[0041] Embodiment 4:

[0045] Working principle: When the device is required to crawl in the pipeline, the device is first placed inside the pipeline. By controlling the electric telescopic rod 11, the moving blocks 3 connected on both sides can be driven to move synchronously. When the moving block 3 moves, it will drive the rotating rod 9 to move and rotate, thereby driving the rotating plate 8 to rotate. When the rotating plate 8 rotates, it will drive the rotating rods 9 on the other two sides to rotate, realizing the simultaneous extension and retraction of the four moving blocks 3, so that the electric wheels 6 on the moving blocks 3 can be in close contact with the inner wall of the pipeline;

[0046] At this time, the device can crawl in the pipeline by controlling the forward and backward movement of the electric wheel 6 through wireless remote control. During the crawling process, the cleaning scraper 15 can scrape the dust on the path to prevent the electric wheel 6 from being affected by the dust, thereby improving the anti-slip effect of the device. The detection camera 17 can detect and record the internal situation of the pipeline.
