Abstract

The invention provides a pneumatic mechanical rust removing device and technology for inner wall of an irregular small-caliber pipe. The device is characterized by comprising a vibrating mechanism, arotating mechanism and a mounting mechanism, wherein the vibrating mechanism comprises a base and a top seat; a pneumatic unit is arranged in the middle of the base; the rotating mechanism comprises abase plate and a rotating disc; the mounting mechanism comprises a workbench; a fixing clamp for mounting the special-shaped small-caliber pipe is arranged on the workbench; and the top seat and thebottom plate are fixedly connected through a connecting column. According to the device, the frequency of a pneumatic solenoid valve can be freely adjusted, different frequency can be selected based on different irregular small-caliber pipes, and thus multi-angle vibration can be realized; the angle of the workbench can be changed by adjusting the telescopic length of a telescopic column; and therotating mechanism enables rotation within a certain time through the rotating mechanism, so that the whole workbench can continuously rotate.

Description

technical field [0001] The invention belongs to the field of rust removal and polishing, and relates to special-shaped small-diameter pipes, in particular to a pneumatic mechanical derusting device and process for the inner wall of special-shaped small-diameter pipes. Background technique [0002] With the development of the industrialization process, the development of technical fields such as construction industry and pipeline transportation is advancing by leaps and bounds. In these application fields, a large number of metal pipes of different shapes are involved and used. [0003] In the follow-up maintenance of metal pipes, rust removal is a relatively important operation. As we all know, the rust removal on the outer surface of metal pipes is relatively simple, but the inside of the metal pipe is usually more complicated because of the thinner pipe diameter and the tortuous internal structure of special-shaped small-diameter pipes. . [0004] At present, we have the ...
