Pipeline inner wall derusting device

Abstract

The invention discloses a pipeline inner wall derusting device. The pipeline inner wall derusting device comprises a fixing mechanism, a driving motor, a connection seat and two bilaterally-symmetrical derusting mechanisms with the connection seat as a center; the fixing mechanism comprises a fixing plate, two positioning plates, a conveying motor and a threaded conveying rod; the center positionof the right end surface of the driving motor is rotationally connected with the left end of the threaded conveying rod, the left end surface of the driving motor is connected with a hollow box with an inner cavity being of a hollow structure through two connection rods, the driving motor rotationally penetrates through the right end surface of the hollow box through a power shaft and is connectedwith a first bevel gear located in the inner cavity of the hollow box, and the side wall of the front side of the inner cavity of the hollow box is rotationally connected with a second bevel gear through a hinge pin; and the two derusting mechanisms each comprise a threaded rod, a threaded sleeve, a sliding sleeve, a plurality of adjusting blocks annularly and uniformly distributed at intervals,and a plurality of cleaning hairbrushes annularly and uniformly distributed at intervals. The pipeline inner wall derusting device can adapt to pipelines different in opening diameter conveniently, quickly conduct feeding and derusting and blow away removed iron rust.

Description

technical field [0001] The invention relates to the related technical field of derusting the inner wall of a pipeline, in particular to a derusting device for the inner wall of a pipeline. Background technique [0002] In recent years, with the rapid development of transportation, industry, agriculture and construction, the pipeline transportation system is used in all aspects of civil and industry, and people pay more and more attention to the utilization of pipeline transportation technology. It has obvious advantages, but because the materials transported in the pipe travel through the pipe for a long time, and due to the influence of chemical corrosion inside the pipe and factors outside the pipe, rust will inevitably appear on the bottom of the pipe and on the pipe wall, and the rust attached to the pipe wall is to a large extent It hinders the smooth passage of transport materials. At present, some inner wall derusting devices have insufficient traction, which seriousl...

[0002] In recent years, with the rapid development of transportation, industry, agriculture and construction, the pipeline transportation system is used in all aspects of civil and industry, and people pay more and more attention to the utilization of pipeline transportation technology. It has obvious advantages, but because the materials transported in the pipe travel through the pipe for a long time, and due to the influence of chemical corrosion inside the pipe and factors outside the pipe, rust will inevitably appear on the bottom of the pipe and on the pipe wall, and the rust attached to the pipe wall is to a large extent It hinders the smooth passage of transport materials. At present, some inner wall derusting devices have insufficient traction, which seriously affects the working distance; and due to the influence of the working environment, slipping often occurs. For some pipes with a lot of rust on the pipe wall, the derusting effect is not good. Affect the long-term effective use of the pipeline, so a kind of rust removal device for the inner wall of the pipeline is designed and produced here to solve the above problems
