Description

Technical Field

[0001] The invention relates to the technical field of steel structure processing, and in particular to a steel structure painting device capable of evenly spraying paint. Background Art

[0002] The structure made mainly of steel is one of the main types of building structures. The characteristics of steel are high strength, light weight, good overall rigidity, and strong deformation ability. Therefore, it is particularly suitable for building large-span, super-high, and super-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well. The construction period is short. It has a high degree of industrialization and can be produced with a high degree of mechanization. Most steel structures need to be painted before they can enter the market. Since the existing method of painting steel structures is generally manual spraying with a spray gun, it cannot ensure that all positions on the steel structure are covered with paint, and the paint is wasted due to excessive paint on the surface of the steel structure, and the paint is unevenly sprayed on the surface of the steel structure. Workers may be splashed with paint during the painting process, which may cause harm to the workers' health and bring certain adverse effects to actual use. Secondly, most spray paints can only be sprayed one side at a time. After one side is dried, the other side is sprayed, which also wastes labor, so improvements are needed. Summary of the invention

The spraying hole is also small to squeeze the spraying material, so that the sprayed material is more dispersed, so as to achieve a uniform spraying effect. 4. The present invention sets a limiting mechanism. When in use, the steel structure squeezes the C-type clamping block. The friction block on the C-type clamping block can increase the friction between the device and the steel structure, making it easier to achieve the clamping effect. The C-type clamping block drives the tension spring and also drives the second limit plate. The second limit plate drives the second sliding block to slide in the storage block.
