Pipeline inner surface cleaning device

Abstract

A device for cleaning the inner surface of a pipe, comprising a transmission flexible shaft (100), a support (200), a driving device (300), and a cleaning assembly (500). The transmission flexible shaft (100) is provided with opposite first and second ends; the support (200) is circular and is coaxially connected to the first end; several rollers in contact with the inner wall of the pipe (1) are arranged at the periphery of the support (200) at intervals; the driving device (300) is connected to the second end, and can transfer a torque force to the support (200) by means of the transmission flexible shaft (100), so as to drive the support (200) to move along the length direction of the pipe (1); the cleaning assembly (500) is positioned at one side of the support (200) away from the driving device (300), and is coaxially connected to the support (200). The device for cleaning the inner surface of a pipe can convey the cleaning assembly (500) to a preset position so as to observe the inner surface of the pipe (1) by means of the cleaning assembly (500), and can also place an object to be conveyed in front of the support (200) along a movement direction thereof so that the support (200) conveys the object to be conveyed to a target position. Compared with the prior art, it is not required to dismount or cut a pipe, and thus a lot of manpower, material resources, and time can be saved.

Description

technical field [0001] The invention relates to the technical field of pipeline system operation, in particular to a pipeline inner surface cleaning device. Background technique [0002] There are many types of pipeline systems in ships and industries, with various diameters, twists and turns, and different materials. During the production, installation and maintenance of the pipeline, certain parts of the pipeline will be cleaned and treated. It cannot be completely manually entered into the pipeline for treatment, but can only be treated by dismantling the pipeline or other methods. [0003] Some pipes have a long length and a large number of bends. When the inner surface of the pipe needs to be inspected, if the inner surface needs to be cleaned, the pipe section can only be removed; for pipes connected with detachable joints such as flanges, etc. The pipeline can be removed directly, but if the pipeline is connected by butt welding or sleeve welding, it needs to be cut ...

Problems solved by technology

During the production, installation and maintenance of the pipeline, some parts of the pipeline will be cleaned and treated. It cannot be completely manually entered into the pipeline for treatment, but can only be treated by dismantling the pipeline or other methods.

[0003] Some pipes have a long length and a large number of bends. When the inner surface of the pipe needs to be inspected, if the inner surface needs to be cleaned, the pipe section can only be removed; for pipes connected with detachable joints such as flanges, etc. The pipeline can be removed directly, but if the pipeline is connected by butt welding or sleeve welding, it needs to be cut before processing, especially when there are other objects blocking the welding connection position, the surrounding objects must be removed , it takes a lot of manpower and material resources, and takes a long time to work
