Technical Field

[0002] Pipeline internal inspection is an integrity evaluation method used to locate defects and preliminarily describe defect characteristics. The effectiveness of internal inspection depends on the condition of the inspected pipe section and the matching of the internal detector with the inspection requirements. It uses mechanical sensing or magnetic induction principles to detect geometric changes in the pipeline and determine its size and location.

[0003] After searching, the patent number CN116857482A is named as an invention of a pipeline internal detector traction device, including a winch, a cable and an anchoring robot. Through research and analysis, it is found that although the traction device has the advantages of very convenient and accurate round-trip operation of the internal detector, it still has the following disadvantages to a certain extent;

[0004] For example, a large amount of dirt and impurities may occur inside the pipeline due to long-term bonding, which may cause difficulties in the repair work. If the pipeline cannot be cleaned in advance, the sediment and dirt may cover up the cracks, corrosion, deformation and other problems inside the pipeline, and cannot better expose the true situation inside the pipeline, which is easy to affect the judgment of the detection results, and the detection and use of the traction equipment is restricted. There is no structure on the traction equipment that is easy to disassemble and install. Complex tools or multiple steps are required to disassemble and install the traction equipment. It is difficult for the traction equipment to quickly adjust the connection according to connectors of different specifications, which affects the progress of the detection work. In order to solve the above technical problems, it is necessary for us to design a traction device for the pipeline detection device to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to provide a traction device for a detection device in a pipeline, which has the advantages of being able to clean the pipeline in advance and helping to improve the detection efficiency, and is convenient for disassembling and assembling connecting parts, thereby solving the problem that a large amount of impurities inside the pipeline bring difficulties to the repair work and the traction device is difficult to quickly adjust the connection according to connecting parts of different specifications.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model can remove impurities in the pipeline and improve the accuracy of detection data through the cooperation of a screw, a support plate, a driving motor, an electric telescopic rod, a support rod, a support cylinder, a brush plate, a support rod and a turntable. The turntable drives the screw to perform a threaded operation, so that the support plate can adjust the usability of the dust removal mechanism according to the inner diameter of the pipeline. The electric telescopic rod is driven to extend and retract to pull the support rod to tilt and push the support cylinder to make the spacing between the brush plates adjustable, so that the brush plates are in close contact with the inside of the pipeline. The driving motor is driven to make the brush plates in all-round contact with the pipeline to improve the dust removal efficiency, avoid sediment and dirt covering the cracks inside the pipeline, and make the detection work more efficient.

[0014] 2.
