Hot runner zinc spraying device for power transmission line steel tube tower

Abstract

The invention provides a hot runner zinc spraying device for a power transmission line steel tube tower. The device comprises two vertical frames which are vertically arranged, steel tube clamping mechanisms are arranged on the upper portions of the sides, close to each other, of the two vertical frames, a rectangular frame is horizontally welded to the upper ends of the two vertical frames, a sliding plate is slidably arranged at one end of the upper portion of the rectangular frame, a moving seat is welded to the lower ends of four stand columns, zinc spraying assemblies are arranged on the two sides of the moving seat correspondingly, a rotating gear ring is rotationally arranged on the outer wall of one side of the moving seat around a passing opening by one circle, and a rotating roller is horizontally and rotationally arranged at the end, away from the moving seat, of the rotating gear ring. According to the invention, the isolation and storage of the surface of the steel tube tower after spraying zinc treatment are realized; different from traditional multiple procedures, the equipment saves procedures, is simple in structure, low in cost and more uniform in film winding, a film roll can be automatically released according to the pulling speed of a film, the situation that the film is broken midway due to the fact that the film is pulled out purely through pulling force is avoided, and the winding and laminating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of zinc spraying equipment, in particular to a hot runner zinc spraying device for steel pipe towers of transmission lines. Background technique [0002] The principle of thermal spraying zinc can be summarized as follows: firstly use high-pressure air and pipelines to blow sand particles to the surface of the workpiece to remove rust and scale on the metal surface, and at the same time increase the adsorption force of the thermal spray coating by increasing the hemp on the surface, and then use oxygen, acetylene or electric heat source ( Electric heating is used for large workpieces, and oxygen and acetylene heating are used for small and medium-sized workpieces). Zinc atomization is sprayed onto the metal surface at super high speed through compressed air and special tools (spray guns). During the production process of steel pipe towers, steel pipes are rolled and welded. After scraping the coiled pipe, it...

AI Technical Summary

Problems solved by technology

[0003] After the zinc spraying of the steel pipe tower, it is necessary to wrap the steel pipe surface with a film to temporarily isolate it from the air, so as to ensure the subsequent maintenance of the anti-rust effect, but the existing film wrapping process needs to be removed and moved to another location after the zinc spraying operation. Wrapping increases the production process and reduces efficiency, and the efficiency of existing film wrapping is also slow and uneven. Therefore, a hot runner zinc spraying device for steel pipe towers of transmission lines is now proposed.
