Annular saw blade mechanism and pipeline cleaning equipment

Abstract

The invention provides an annular saw blade mechanism, and relates to the field of pipeline cleaning equipment. The annular saw blade mechanism comprises an annular saw blade and a supporting assembly. The annular saw blade is formed by winding a long-strip-shaped saw blade. The head and tail ends of the annular saw blade are overlapped, so that an overlapped section is formed on the annular saw blade; the inner diameter of the annular saw blade can be changed by adjusting the length of the overlapping section; the supporting assembly is fixedly connected with the annular saw blade and used for supporting and fixing the annular saw blade. The supporting assembly is further used for being in transmission connection with an external driving mechanism so that the external driving mechanism can drive the annular saw blade to rotate through the supporting assembly. The outer diameter of the supporting assembly is adjustable; the outer diameter of the annular saw blade mechanism can be changed by adjusting the inner diameter of the annular saw blade and the outer diameter of the supporting assembly. The invention further provides pipeline cleaning equipment, and the outer diameter of the annular saw blade mechanism can be adjusted according to use requirements so as to adapt to pipelines with different inner diameters.

Description

technical field [0001] The invention relates to the field of pipeline cleaning equipment, in particular to an annular saw blade mechanism and pipeline cleaning equipment. Background technique [0002] With the continuous deepening of urbanization, the scale of Chinese cities is getting larger and larger, and the urban underground pipe network is also becoming larger and more complex. The manpower and material resources required for the cleaning of urban underground sewage pipes are also gradually increasing. The level of pipeline cleaning and maintenance and supporting equipment needs to be developed rapidly to meet the cleaning needs of sewage pipelines, and pipeline cleaning robots have emerged as the times require. [0003] The internal environment of the pipeline is complicated, and it is usually necessary to use a saw blade mechanism to cut off the tree roots growing in the pipeline during the process of cleaning the pipeline; the existing saw blade mechanism cannot ad...

Problems solved by technology

[0003] The internal environment of the pipeline is complicated. In the process of cleaning the pipeline, it is usually necessary to use a saw blade mechanism to cut off the tree roots growing in the pipeline; the existing saw blade mechanism cannot adjust its outer diameter according to the size of the inner diameter of the pipeline, resulting in inconvenient use
