Description

Steel pipe rust cleaning device that polishes for bridge construction

Technical Field

The invention relates to the technical field of steel pipe rust removal, in particular to a steel pipe polishing and rust removal device for bridge construction.

Background

When the bridge construction is built, due to storage and external environment reasons, the surface of the steel pipe placed for a long time can generate iron rust, when the steel pipe is serious, a small amount of rusting even occurs in the steel pipe, and in order to avoid the influence of rusting of the steel pipe on the construction quality of the bridge, the surface of the steel pipe needs to be subjected to rust removal treatment when the steel pipe is put into use.

Through retrieval, the Chinese patent with the publication number CN211517079U discloses a steel pipe polishing and rust removing device for bridge construction.

The technical scheme is as follows: the novel steel tube support base comprises a base, T-shaped slide rail grooves are formed in the top of the base, a support plate is welded and fixed to the top of the base and close to the right side, and a steel tube support plate is welded and fixed to the top of the base and close to the left side.

When the patent uses, place the base on ground, the one end of steel pipe is passed the bearing and is filled in and place the recess, screw up fixing bolt and fix the steel pipe, it drives the steel pipe and rotates on the bearing to open the motor again, the in-process fixed block of polishing and bearing carry on spacingly to the steel pipe, it is more even to make the surface of steel pipe polish, the in-process of polishing, promote the movable block and remove the position that comes the regulation emery wheel on T shape slide rail groove, when the angle of polishing that needs the regulation emery wheel, the hand wheel is rotated and is driven the regulation pole and rotate the angle of adjusting the emery wheel.

However, the invention has the following disadvantages: when the steel pipe rust remover is used, only a single steel pipe can be polished once, and meanwhile, only the outer wall of the steel pipe can be polished and derusted, so that the processing requirement cannot be met when the steel pipe is faced with some internal partially rusted steel pipes, meanwhile, the whole steel pipe rust remover is designed in an open mode, and when the steel pipe rust remover is used for polishing a grinding wheel, rust can splash in a large range, so that the steel pipe rust remover causes adverse effects to a processing environment, and has limitations.

Therefore design a steel pipe rust cleaning device that polishes for bridge construction, can once derust to the inside and outside lateral wall of many steel pipes, simultaneously, avoid the rust slag to splash to ensure that the processing scene is clean and tidy, be the first-hand problem that technical staff in this field should solve at present.
