Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a crawler for trenchless pipeline repair. Background Art

[0002] A pipeline crawler is a device used for inspecting and repairing defects in various pipelines, such as natural gas pipelines, oil pipelines, urban water supply and drainage pipelines, and tap water pipelines. It is generally composed of a walking mechanism, a detection device for observing and detecting the inner wall of the pipe, a control and communication device, etc. The trenchless pipeline repair technology is to use the original pipe resources without excavation or less excavation, and adopt relevant technologies to install the lining in the existing pipeline to extend the service life of the pipeline.

[0003] During the use of the crawler, the detection device is blocked and blurred due to the dust and humid environment in the pipeline, or the surface of the detection mechanism is contaminated by the sludge inside the pipeline, which affects the user's detection of the situation in the pipeline through the detection device. The existing crawler cannot directly clean the surface of the detection mechanism during detection, and the crawler needs to be retracted and cleaned, which reduces work efficiency, is troublesome to operate, is time-consuming and labor-intensive, and is inconvenient to use.

[0004] Most of the current crawlers are designed to be portable, with the aim of being convenient for inspectors to carry and reducing their workload. Existing crawlers mainly rely on detection mechanisms for inspection and repair, and when not in use, the detection mechanism is exposed on the outside. Existing crawlers cannot protect the detection mechanism, and there are many uncertain factors during the movement process. Dust contamination or damage due to external forces may occur, which greatly shortens the service life of the crawler and affects its subsequent normal use. Utility Model Content

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

[0014] The utility model uses a cleaning brush plate in cooperation with a micro motor to clean the surface of the detection mechanism when it is blocked or becomes blurred during the operation of the detection device, thereby preventing dirt on the surface of the detection mechanism from affecting the normal detection work.

The protective door 10 can be positioned so that it is not easy to be displaced, which is convenient for the detection mechanism to perform detection work. Similarly, when the crawler is not in use, the protective door 10 is flipped to one side of the mounting shell 8, so as to protect the detection mechanism, reduce the risk of damage to the detection mechanism due to external factors, and prevent the detection mechanism from being contaminated by dust.

[0025] It is worth noting that the micro motor 2, micro water pump 61 and crawler body 1 proposed in this technical solution are existing technologies, and the micro motor 2, micro water pump 61 and crawler body 1 are all electrically connected and can be controlled through the same operating panel. The working principles and beneficial effects during use will not be elaborated here.

[0026] Working principle: First, before inspecting the pipeline, pull the protective door 10 upwards, drive the connecting rod 94 to flip synchronously and pull the telescopic spring 93. In the process of flipping the protective door 10 to the top of the installation shell 8, the protective door 10 is guided by the moving groove 12 and the moving block 13. At the same time, under the action of the tension of the telescopic spring 93, the protective door 10 is positioned at the top of the installation shell 8 to avoid the protective door 10 flipping due to external force during use. The normal use of the detection mechanism is affected, and then the crawler body 1 is placed inside the pipeline for inspection. During the repair work, if the surface of the detection mechanism is dirty and affects the observation, turn on the micro motor 2 to control the cleaning brush plate 4 to rotate to clean the dirt on its surface. When there is dirt remaining on the bristles on the surface of the cleaning brush plate 4, turn on the micro water pump 61, and pump the cleaning liquid inside the liquid storage tank 5 to the inside of the water divider 63 through the infusion tube 62 and spray it out through the nozzle 64 to clean the cleaning brush plate 4 to avoid affecting the subsequent cleaning effect on the surface of the detection mechanism. After the repair is completed, pull down the protective door 10 and return it to its position to protect the detection mechanism.
