Pipeline cleaning device

Abstract

The invention discloses a pipeline cleaning device. A triangular mechanism is adopted to enable a tool assembly for cleaning to have an expansion and retraction function so as to adapt to cleaning ofpipelines with different pipe diameters. Two groups of blades with different lengths are provided, since tool handles are hinged to the same position in the axial direction of a spray pipe, on the condition of ensuring that different groups of tools make contact with the inner wall of the spray pipe, contact positions are different in the axial direction of the spray pipe, the tools form two-pointsupporting, and therefore it can be ensured that the cleaning device stably operates. The two groups of blades are paired for use based on two groups of adjusting holes which are arranged in advance,on the condition of pairing use, the edges of the two groups of blades are completely or partially located in a same cylindrical face, and adjustment of the edges is quite easy based on the triangular mechanism.

Description

technical field [0001] The invention relates to a pipeline cleaning device. Background technique [0002] Pipeline cleaning devices mainly include axial flow flushing device, mechanical scraping device, radial flow spray cleaning device, etc., and a composite cleaning device of two or more cleaning devices mentioned above. Different types of pipe cleaning devices often have different applicable objects. For mechanical cleaning devices, limited by their own structure, often the same type of mechanical cleaning device can only clean pipes of one diameter. [0003] Chinese patent document CN108114953A discloses a pipeline dirt cleaning device, which is a composite cleaning device, which is equipped with a spraying pipe with radial water spray holes for generating radial jets. At the same time, a plurality of scrapers are arranged on the spraying end face of the spraying pipe for supporting the spraying pipe and for scraping dirt on the inner wall of the pipe. Although the cle...

Problems solved by technology

The screw nut mechanism is a precision mechanism in the mechanical field, and usually requires good lubrication. When cleaning the pipeline, the working conditions are extremely harsh, and the adaptability of the screw nut mechanism is relatively poor

Because the cleaning device uses high-pressure water jetting and rotating cutter head assembly, the high-pressure water jetting part can adjust the water pressure according to the pipe diameter, while the rotating cutter head assembly needs to be equipped with an independent expansion and contraction mechanism, and the overall structure is relatively complicated.
