Device suitable for rust removal of inner walls of metal pipes with different diameters and different lengths

Abstract

The invention relates to the field of metal materials, and discloses a device suitable for rust removal of inner walls of metal pipes with different diameters and different lengths. The device comprises a main box body, wherein a transmission large gear cavity is formed in the main box body; telescopic gear cavities which are symmetrical left and right by taking the transmission large gear cavityas a center are formed in the left side and the right side of the transmission large gear cavity in a communicating mode; a transmission gear cavity is formed in the left side of the telescopic gear cavity on the left side in a communicating mode; an end face tooth cavity is formed in the lower side of the transmission gear cavity; and a sliding bevel gear cavity, a telescopic advancing wheel anda rust removal brush are arranged on the left side of the transmission gear cavity. According to the device, the device is suitable for rust removal operation of the inner walls of the metal pipes with different diameters, the advancing wheel drives the device to advance, so that rust removal operation of the metal pipes with different lengths can be realized; the rust removal brush is matched with sand blasting for rust removal, so that rust removal of the inner walls of the metal pipes is more thorough; and meanwhile, automatic rust removal of the device replaces manual operation, so that the rust removal effect of the metal pipes is better, the efficiency is higher, and meanwhile, the problem that the rust removal operation of the pipes with the long length cannot be well carried out manually is solved.

Description

technical field [0001] The invention relates to the related field of metal materials, in particular to a device suitable for derusting the inner walls of metal pipes with different diameters and different lengths. Background technique [0002] Metal corrosion is the most common corrosion state of metal, and it is very harmful. Metal rust removal is an important part of metal corrosion protection. In the metal pipe rust removal operation, the rust removal of the inner wall of the pipe is more complicated. At present, the rust removal of the inner wall of the metal pipe is mainly used Chemical reagents clean the inner wall of metal pipes. This method of derusting not only easily causes environmental pollution, but also excessive chemical reagents will cause damage to metal pipes and reduce the service life of metal pipes. At present, there are some devices for derusting the inner walls of metal pipes. However, these device mechanisms are relatively single, and cannot be well a...

[0002] Metal corrosion is the most common corrosion state of metal, and it is very harmful. Metal rust removal is an important part of metal corrosion protection. In the metal pipe rust removal operation, the rust removal of the inner wall of the pipe is more complicated. At present, the rust removal of the inner wall of the metal pipe is mainly used Chemical reagents clean the inner wall of metal pipes. This method of derusting not only easily causes environmental pollution, but also excessive chemical reagents will cause damage to metal pipes and reduce the service life of metal pipes. At present, there are some devices for derusting the inner walls of metal pipes. However, these devices are relatively simple in structure and cannot be well applied to metal pipes with different diameters and lengths for derusting operations.
