Pipeline dredging vehicle with adjustable threaded wheels

Abstract

The invention discloses a pipeline dredging vehicle with adjustable double threaded wheels. The vehicle comprises a pair of threaded wheels symmetrically arranged, a support frame, a mud suction hoodconnected with the support frame and a threaded wheel drive motor. Each threaded wheel comprises a first threaded wheel in the front section, a second threaded wheel in the middle section and a thirdthreaded wheel in the tail section. The threaded wheels in the three sections are connected coaxially. A thread line of each first threaded wheel is a tapered thread line. The support frame comprisesfour pairs of support plates, two first connecting rods and a telescopic rod, two pairs of support plates are arranged between the first threaded wheels and the second threaded wheels, and the other two pairs of support plates are arranged between the second threaded wheels and the third threaded wheels. The two first connecting rods respectively connect all the support plates on the same side. The telescopic rod connects the two first connecting rods. During normal walking and dredging, the threaded wheels rotate to generate forward thrust between the threads and the ground, and the sludge isstirred and broken during the thread rotation, and meanwhile is transported to a mud suction port at the tails of the threaded wheels.

Description

technical field [0001] The invention relates to pipeline dredging equipment, in particular to a pipeline dredging vehicle with adjustable threaded wheels. Background technique [0002] Pipeline dredging is a major problem facing the municipal pipe network. Usually, high-pressure cleaning vehicles are used to scour, or manual traction, push-pull and other methods are used to clean the silt in the pipeline to the outside of the pipeline. These methods are only suitable for dredging projects with relatively light siltation and short-distance pipeline networks. For long-distance and severely blocked pipelines, the construction difficulty and labor intensity will be significantly increased. [0003] For example, the Chinese invention patent application document whose publication number is CN 109440915A discloses a sewer pipeline dredging robot, and the protection level of the whole vehicle reaches IP68. The sewer pipe dredging robot includes a crushing device, a main body struct...

AI Technical Summary

Problems solved by technology

[0005] In order to improve dredging efficiency and reduce operational risks, small robots are used instead of manual downhole operations. However, the internal environment of the pipeline is complex, and the commonly used wheeled and crawler dredging robots often have problems of weak obstacle avoidance and insufficient traction. Pipelines with severe silting cannot play their full role
