Tower crane standard section and anti-corrosion spraying process thereof

Abstract

The invention relates to a tower crane standard section and an anti-corrosion spraying process thereof. The anti-corrosion spraying process of the tower crane standard section comprises the following steps that S1, the diameter of a square pipe is determined, wherein according to the diameter of the square pipe, an outer spraying pipe is controlled to move on a rack through an adjusting device, the distance between an inner spraying pipe and the outer spraying pipe is adjusted, and it is ensured that the outer spraying pipe is located on the outer side of the upper portion of the square pipe; S2, the square pipe is fixed, wherein the end part of the square pipe is fixedly connected with a bracket through a fixing device; S3, the square pipe is rotated, wherein the bracket is controlled to intermittently rotate on the rack through an intermittent assembly; S4, spraying is conducted, wherein in the intermittent movement process of the inner spraying pipe, the inner spraying pipe and the outer spraying pipe start spraying at the same time; and S5, the square pipe is dismantled, wherein the square pipe is dismantled from the bracket, and spraying work is completed; wherein the outer spraying pipe and the inner spraying pipe are horizontally arranged, and a plurality of spraying holes distributed along the same horizontal line are formed in the peripheral walls of the outer spraying pipe and the inner spraying pipe. The tower crane standard section and the anti-corrosion spraying process thereof have the advantages that the working efficiency of square pipe spraying is improved, energy consumption is reduced, resources are saved, and meanwhile the labor intensity of workers is reduced.

Description

technical field [0001] The application relates to the technical field of tower crane standard section processing, in particular to a tower crane standard section and its anti-corrosion spraying process. Background technique [0002] At present, the standard section of tower crane plays an important role in mechanical equipment such as cranes, tower trucks, and elevators. A good standard section can not only improve the stability of these cranes, but also improve the safety performance of the whole machine, so it is said The standard section of the tower crane is an important part of a tower crane. The standard section of the tower crane generally uses angle steel, but more and more manufacturers use square steel. Although the structural strength of square steel is higher than that of angle steel, square steel is a relatively difficult process. It is the spraying of anti-rust paint inside the square steel. [0003] The Chinese patent with the application number CN20162118098...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects. The paint delivery pipe is used to spray paint on the inner wall of the opposite pipe, but it still needs to be sprayed on the outer wall of the opposite pipe separately, and there is a defect that the spraying work is troublesome.
