Steel pipe polishing and derusting device for bridge construction

Abstract

The invention discloses a steel pipe polishing and derusting device for bridge construction. The steel pipe polishing and derusting device comprises a positioning and polishing structure and a sealing structure, the positioning and polishing structure comprises a working frame, a limiting frame, a polishing barrel, a rotating motor, a clamping plate, a telescopic plate, an extrusion air cylinder, a clamping air cylinder and a limiting plate, the rotating motor is installed at the center of one side of the outer wall of the working frame through a bolt, and the center of one side of the outer wall of the clamping plate is fixedly arranged at the output end of the rotating motor. According to the steel pipe polishing and derusting device for bridge construction, efficient positioning and clamping of steel pipes with different pipe diameters can be achieved through the positioning and polishing structure and the sealing structure, in the polishing process, slipping and thread slipping are avoided, eccentric polishing is avoided in the polishing process, and finally the structural strength of steel pipes is not reduced; and in addition, in the polishing and anti-rust paint spraying process, a sealing shell is combined, dust and anti-rust paint generated during rust removal cannot leak into the working environment, so that the working environment of workers is guaranteed, industrial injuries are avoided, and the practicability of the steel pipe polishing and derusting device is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, in particular to a steel pipe grinding and derusting device for bridge construction. Background technique [0002] Highway and bridge construction, often combined with the local construction environment, will use a large number of prefabricated structures, steel pipes and cement. Among them, the treatment of steel pipes will directly affect the progress and quality of the project. [0003] Steel pipes refer to steel materials for concrete-filled steel pipes and prestressed steel pipes for concrete-filled steel pipes. The straight or coiled steel used for reinforcement can be divided into two types: smooth round steel tube and deformed steel tube, and the delivery state is straight and coiled. [0004] With the state's investment in infrastructure construction in the western region in recent years, more and more road construction companies need to overcome the environment in the ...

AI Technical Summary

Problems solved by technology

[0005] For construction in the actual saline desert soil environment, the strength and tensile properties of steel pipes need to be improved first, and the anti-corrosion performance of steel pipes must be tested to ensure that the steel pipes will not be corroded and broken during the entire life cycle of the project. problem, but there is no guarantee that there will be no corrosion. The adjustment of the structural strength of the steel pipe requires the production of the steel pipe. In order to meet the design requirements, the inside of the steel pipe often needs to form austenite. When grinding the outer wall of the round pipe, the actual During the production process, the safety is not enough, and the debris splashing on site is relatively serious. After a long time of use, it is easy to generate a large amount of metal debris accumulation, which eventually leads to the problem of equipment jamming. Secondly, in the production process, the clamping of the equipment The work is often clamped and fixed by clamps. When dealing with different steel pipes, the clamps need to be replaced frequently, and the actual production efficiency is low.
