Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline cleaning, in particular to a pipeline inner wall rust removal machine. BACKGROUND

[0002] The inner wall of a pipeline for exploiting oil or transporting oil has rust and other impurities after long-term use, and needs to be cleaned and maintained before it can continue to be used. The existing cleaning methods include the following two methods:

[0003] One is to use a high-pressure water gun to spray high-pressure water for cleaning, which has the problems of incomplete cleaning, serious environmental pollution, water consumption and energy consumption.

[0004] The other is to use a steel wire brush, such as the steel pipeline inner wall rust removal machine disclosed in Chinese Patent No. CN104440491A, which is named a steel pipeline inner wall rust removal machine. When cleaning, the rust removal machine is placed at the position to be cleaned in the steel pipeline, and the steel wire brush is in contact with the inner wall of the steel pipeline. The steel wire fixed on the steel wire brush moves in a circular motion together with the steel wire brush. When the steel wire moves around the axis of the steel wire brush and passes through the position of the steel wire brush shaft, the steel wire brush shaft produces a blocking effect on the steel wire. This blocking effect causes elastic deformation of the steel wire. The elastic deformation of the steel wire causes the steel wire to lag behind the rotation of the steel wire brush, and produces deformation in the opposite direction of rotation. When the deformation of the steel wire reaches a certain degree, the steel wire slides over the steel wire brush shaft. After the steel wire slides over the steel wire brush shaft, the potential energy is released and converted into kinetic energy to produce a very high speed to hit the inner wall of the steel pipeline. Under the continuous and constant hitting action of the steel wire, the rust is stripped off. The steel pipeline inner wall rust removal machine has the problems of complex equipment, complicated rust removal method, high procurement cost and inconvenient operation. SUMMARY
