Novel derusting device for design and processing of fabricated steel structure

Abstract

The invention discloses a novel derusting device for design and processing of a fabricated steel structure, and belongs to the technical field of derusting of steel structures. The novel derusting device comprises two arc-shaped supporting plates and two elastic arc-shaped connecting plates. Supporting rods rotate to drive cleaning brushes to brush and clean rust on the inner wall of steel, so that the inner wall of the steel can be kept clean, and the situations that the rust on the inner wall of the steel cannot be cleaned in time, consequently, the steel is continuously rusted, and therefore the service life of the steel is shortened, and the use stress strength is reduced are avoided. A moving frame is driven to move once when every two supporting rods rotate and pass through rolling wheels, so that the cleaning area of the cleaning brushes is larger than the moving distance of the moving frame, and the situation that the inner wall of the steel cannot be completely cleaned due to the fact that the moving frame moves too fast is avoided. In the rotating process of the supporting rods, the supporting rod acts on air bags to collect the cleaned rust slag on the inner wall of the steel, and the situation that the residual rust slag affects assembly of workpieces is avoided.

Description

technical field [0001] The invention relates to the technical field of derusting steel structures, in particular to a novel derusting device for design and processing of assembled steel structures. Background technique [0002] When building buildings and carrying out bridge and road construction, a large number of building steel structures will be used. The building steel structure is easy to oxidize with oxygen and water vapor in the air to produce rust in the storage room. The cross-section of the steel structure is usually rectangular or circular. , by screwing or welding the steel structures can be connected and fixed. [0003] When the derusting device in the prior art derusts the round steel, it generally only derusts the surface of the steel, but when the steel is stored, the inside of the steel will also be rusted, and the service life of the steel will be affected by the rust. It is affected to a certain extent, and the rust generated inside the steel is generally...

Problems solved by technology

[0005] The object of the present invention is to provide a new type of derusting device for the design and processing of assembled steel structures, to solve the problem of derusting in the prior art in the above-mentioned background technology When the device derusts the round steel, it generally only derusts the surface of the steel, but when the steel is stored, the inside of the steel will also appear rusty, and the service life of the steel will be affected by the degree of rust, and the inside of the steel The generated rust is generally difficult to clean up. If the rust is not removed in time, it will lead to continuous corrosion of the steel, which will shorten the service life of the steel and reduce the strength of the steel. Errors in the judgment of force strength further affect the overall quality of the project
