Spraying device for assembly type steel structure

Abstract

One or more embodiments of the invention provide a spraying device for an assembly type steel structure. The spraying device comprises a barrel, wherein the barrel is designed to be a transversely placed hollow cylinder, the steel structure is transversely conveyed in the barrel through a conveying device at the inner bottom end of the barrel, a sliding groove is fixedly formed around the inner wall of the barrel in the circumferential direction, spraying heads are clamped on the sliding groove, the spraying heads are connected with a spraying hose, the spraying hose penetrates out of the barrel and is externally connected to a spraying machine body, when the steel structure is conveyed to pass through the sliding groove, the surface of the steel structure can be comprehensively and evenlysprayed through the spraying heads arranged on the sliding groove in the circumferential direction while the steel structure is conveyed, and meanwhile, the spraying heads can slide in the circumferential direction of the sliding groove, limiting springs are arranged in the sliding groove, one ends of the limiting springs are fixedly connected to the spraying heads, the other ends of the limitingsprings abut against the inner wall of the sliding groove so that the spraying heads can be fixed and limited through the limiting springs, the positions of the spraying heads can be flexibly adjusted according to steel structures of different styles, and efficient and uniform spraying is achieved.

[0002] The prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories are processed and manufactured, transported to the construction site, and assembled and installed on site through reliable connection methods. , among them, due to its anti-corrosion, heat insulation, fire resistance and temperature resistance and other performance requirements, the assembled steel structure needs to be sprayed on the surface. The existing spraying equipment can be divided into manual spraying equipment and semi-automatic spraying equipment according to the degree of automation. There are three kinds of automatic spraying equipment and automatic spraying equipment. When spraying many workpieces, it is obvious that manual spraying is not only time-consuming and laborious, but also the spraying environment brings certain harm to the health of the workers. Mount the workpiece to complete the spraying, so that the efficiency is low, and in order to make the spraying uniform, it is often necessary to clamp different end faces of the workpiece, or set the drive unit to drive the workpiece to turn over or drive the spraying port to move along the surface of the workpiece, so as to realize the spraying of the workpiece. The comprehensive and uniform spraying will lead to low spraying efficiency, which is not conducive to large-scale mass production, especially the batch spraying processing of fabricated steel structures. In addition, because most of the steel structures are of high quality, frequent driving and flipping of workpieces will obviously bring greater At the same time, due to the diverse appearance of steel structures, the spraying methods of existing automatic spraying devices are often relatively fixed, so it is often impossible to flexibly adjust for different styles of steel structures to adapt to the uniformity of different steel structures. Comprehensive and efficient spraying, so that the applicability is not good, and it cannot meet the needs of high-quality spraying, and the method of driving the spraying port to move along the surface of the workpiece also has the problems of relatively difficult design and low efficiency, and the practicability is not good.
