High-speed railway bridge surface shot blasting machine

Abstract

The invention relates to a high-speed railway bridge surface shot blasting machine. According to the technical scheme provided by the invention, an electric device control box is installed at the upper part of a rack, and the electric device control box is provided with a shot handle; a rebound high-pressure chamber is installed in front of the rack, and the outlet on the tail end of the rebound high-pressure chamber is connected with the material inlet of a separating system, wherein the separating system is further provided with a cleaner connection opening and a shot charging opening; a material storage hopper connected with the shot charging opening is installed at the shot charging opening of the separating system, and the lower part of the material storage hopper is connected with a material feeding tube; a magnetic valve is arranged between the material storage hopper and the inlet end of the material feeding tube, and the magnetic valve is connected with the shot handle on the electric device control box and controlled by the shot handle; the lower end inlet of the rebound high-pressure chamber is connected with the short rebound opening of the shot blasting mechanism, and a shot blasting opening is arranged on the lower end of the shot blasting mechanism; and a drive travelling system is arranged at the bottom of the shot blasting mechanism. The machine has smart and reasonable structure, excellent processing effect, and safe and reliable operation.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular relates to a high-speed rail bridge deck shot blasting machine which uses high-speed projectiles thrown by a shot blaster to clean or strengthen the ground. Background technique [0002] In the service life of high-speed rail bridge structures, the waterproof structure of the bridge deck is one of the key factors. After long-term practice and exploration in our country, we have gradually realized the importance of construction technology and methods for the quality of railway bridge waterproof structures, especially the treatment of the bridge surface base layer, which directly affects the bonding effect between the bridge deck waterproof layer and the concrete base layer, and has become One of the controlling factors of bridge deck waterproof quality. At present, the surface treatment methods used in my country include: artificial chiseling, mechanical chiseling, hig...

AI Technical Summary

Problems solved by technology

At present, the surface treatment methods used in my country include: artificial chiseling, mechanical chiseling, high-pressure water treatment, etc., which generally have low construction efficiency, poor surface treatment quality, and serious environmental pollution.

[0003] The production and application of shot blasting technology has a history of more than 100 years abroad, and their shot blasting equipment and technology are relatively mature, but they are rarely used in China.
