Derusting machine for inner wall of steel tube

Abstract

The invention discloses a derusting machine for the inner wall of a steel tube. The derusting machine comprises a box body, wherein a dedusting cavity and a moving cavity are arranged in the box body,a motor seat is arranged in the dedusting cavity, a dedusting motor is arranged on the motor seat, the output end of the dedusting motor is connected to a rotating shaft, a compression spring is arranged on the rotating shaft, a dedusting rod is arranged on the compression spring, and a friction wheel is arranged on the dedusting rod; a mounting seat and a supporting seat are arranged in the moving cavity; a first servo motor is arranged on the mounting seat, the output end of the first servo motor is connected to a lead screw, a lead screw nut is arranged on the lead screw, and a plurality of movable rods are arranged on the lead screw nut; a stripe-type through hole is formed in the box body, and the movable rod penetrates through the through hole and is hinged to a first supporting rod; a second supporting rod is arranged on the box body, one end of each of the second supporting rod and the second supporting rod is hinged to the box body, separately, while the other end of each ofthe second supporting rod and the second supporting rod is separately connected to a clamping block; and a walking mechanism is arranged on each clamping block. The dedusting machine disclosed by theinvention can be suitable for pipelines of different diameters and lengths, and has the advantages of being simple to operate, convenient to use and good in dedusting effect.

Description

technical field [0001] The invention relates to a derusting device, in particular to a derusting machine for the inner wall of a steel pipe. Background technique [0002] Pipes such as steel pipes and cast iron pipes are widely used in the technical fields of petroleum, chemical industry, water supply and drainage, power stations, papermaking, leather, ventilation and extraction of corrosive gas chimneys in China. There is a lot of rust on the inner wall. When it is used again, in order to ensure the normal use and service life of the pipeline, it is necessary to remove the rust on the inner wall of the pipeline. At present, for example, Chinese published patent CN201520427074.3 discloses a round steel pipe inner wall derusting machine, which is mainly used for round steel pipe inner wall rust removal. But this patent has the following disadvantages. The first needs to artificially move the derusting machine by the push rod. If the push rod is too short, the rust problem of...

Problems solved by technology

However, this patent has the following disadvantages. First, it is necessary to manually move the derusting machine through the push rod. If the push rod is too short, the rust on the inner wall of the long pipe cannot be removed.

Second, if the pipe is too large or too small, it will not be used effectively, and in the pipe that is too large, the walking frame will be unstable, and it will be difficult to maintain balance effectively during the rust removal process
