Pipeline inner wall clearing device used for pipeline repairing through insertion method

Abstract

The invention relates to the technical field of pipeline repairing, in particular to a pipeline inner wall clearing device used for pipeline repairing through an insertion method. The pipeline inner wall clearing device comprises a shell, a traction rope is arranged at one end of the shell, two sets of distance adjusting mechanisms are arranged on the circumferential surface of the shell, a plurality of high-pressure nozzles are arranged on the circumferential surface of the shell, the shell is internally provided with a water supply pipe communicating with all the high-pressure nozzles, and the distance adjusting mechanisms are located at the two ends of the shell correspondingly; and each distance adjusting mechanism comprises a plurality of supporting rods arranged on the outer circumferential surface of the shell, one end of each supporting rod is hinged to the shell mutually, the other end of each supporting rod is rotationally connected with a supporting wheel, an auxiliary supporting rod is further arranged on each supporting rod, one ends of the auxiliary supporting rods are connected with the supporting rods, sliding blocks are hinged to the other ends of the auxiliary supporting rods, an outer thread is formed on the outer circumferential surface of the shell, and the outer circumferential surface of the shell is in threaded connection with clamping rings for limitingthe sliding positions of the sliding blocks. The pipeline inner wall clearing device has the effects that the physical output of labor is reduced, and the cleaning efficiency to the inner wall of a pipeline.

Description

technical field [0001] The present application relates to the field of pipeline repairing equipment, and in particular, to a pipeline inner wall cleaning device used for pipeline repairing by interpenetration method. Background technique [0002] The urban municipal pipe network system is an important part of urban infrastructure. With the continuous improvement of urbanization in my country, the length of the newly laid and updated municipal pipe network has exceeded 100,000 kilometers every year in recent years. The transformation of the existing urban pipeline network is an unavoidable problem in the process of urban development. If the method of excavation and replacement is fully adopted in the renewal process of the urban underground pipe network, not to mention the huge expenditure, the environmental problems, traffic problems and the impact on the residents' lives will be quite large. It is a strong requirement for urban construction and modern social life to adopt ...

Problems solved by technology

The existing high-pressure water flushing method mainly adds a high-pressure nozzle at one end of the water pipe, and through the water supply of the water pump, the high-pressure nozzle ejects a high-speed water column to flush the inner wall of the pipeline, but the area where the high-pressure nozzle is installed is limited, and the sta
