Cleaning and corrosion-preventing robot for inner wall of variable-diameter pipeline and using method

Abstract

The invention discloses a cleaning and corrosion-preventing robot for an inner wall of a variable-diameter pipeline and a using method. The robot comprises a center rack, a pipeline inner wall cleaning assembly, a walking assembly and a pipeline inner wall preservative liquid spraying assembly which are sequentially arranged on the center rack from front to back. The method comprises the steps of: feeding the whole robot into a pipeline, making the walking assembly and the pipeline inner wall cleaning assembly in full contact with the inner wall of the pipeline, firstly starting the pipeline inner wall cleaning assembly, then starting the walking assembly, and making the whole robot to advance forwards at a constant speed in the length direction of the pipeline; when the pipeline inner wall preservative liquid spraying assembly moves to the cleaning starting position, starting the pipeline inner wall preservative liquid spraying assembly, and along with continuous forward movement of the robot, continuously carrying out cleaning and preservative liquid spraying operation on the inner wall of the pipeline; and when the robot moves to the variable-diameter position of the pipeline, if the inner diameter of the pipeline is increased, increasing the radial size of the pipeline inner wall cleaning assembly and the radial size of the walking assembly, and vice versa until cleaning of the inner wall of the variable-diameter pipeline and spraying of preservative liquid are completed.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning and anticorrosion, and in particular relates to a variable-diameter pipeline inner wall cleaning and anticorrosion robot and a use method thereof. Background technique [0002] At present, a large number of pipeline facilities are used in people's production and life, and the types, styles and sizes of these pipeline facilities are also different, which brings new problems to the cleaning of the inner wall of the pipeline and the spraying of anti-corrosion fluid on the inner wall of the pipeline. difficult. At present, the cleaning of the inner wall of the pipeline and the spraying of anti-corrosion fluid are mainly done manually, but for pipelines with too large diameter, too small diameter or too long length, it is difficult to guarantee the effect of manual cleaning of the inner wall of the pipeline, not only the labor intensity is high, but also the work low efficiency. In addition...

Problems solved by technology

[0003] Aiming at the problems existing in the prior art, the present invention provides a variable-diameter pipe inner wall cleaning and anticorrosion robot and its use method, which can replace the traditional manual method to complete the cleaning of the inner wall of the pipe and the spraying of anticorrosion liquid, and can adapt to pipes with different inner diameters. It effectively reduces the labor intensity of the staff, not only can ensure the cleaning effect of the inner wall of the pipeline, but also effectively improves the work efficiency. A health hazard occurs
