Semi-automatic on-site sandblast derusting equipment

Abstract

The invention discloses semi-automatic on-site sandblast derusting equipment. The semi-automatic on-site sandblast derusting equipment comprises a horizontal walking guide rail detachably fixed to anobject to be subjected to sandblast, a horizontal walking trolley which is arranged on the horizontal walking guide rail and can walk along the horizontal walking guide rail, a vertical walking trackdetachably fixed to the object to be subjected to sandblast, and a vertical walking trolley which is arranged on the vertical walking track and is driven by a drive device to move up and down along the vertical walking track, wherein the horizontal walking trolley and / or the vertical walking trolley are / is provided with sand-blasting guns, and a conversion butt connection mechanism is arranged ata joint of a horizontal welding line and a vertical welding line. The semi-automatic on-site sandblast derusting equipment can carry out sand-blasting treatment on the horizontal welding line and thevertical welding line on a vertical face and is high in production efficiency, low in labor intensity and good in safety performance.

Description

technical field [0001] The invention relates to a small semi-automatic on-site sandblasting and derusting equipment, which belongs to the field of sandblasting and derusting. Background technique [0002] At present, in the construction of large-scale storage tanks (cabinets) in China, the diameter of large-scale storage tanks (cabinets) is generally more than 10-30 meters, and the height is about 10-40 meters. Treatment, after spraying anti-rust paint, welding and assembly on site, the length of the welds is long, and most of them are welds on the vertical steel plate surface. General construction units use manual and electric tools to grind these welds to remove rust. This method has low work efficiency, high labor intensity, great safety hazards, and low rust removal quality. Generally, it reaches St2 or even lower. And the quality is unstable, and the human factor is large. If the sandblasting process is used, only open sandblasting can be used, which can ensure the qu...

Problems solved by technology

[0003] If the quality of weld derusting is not good, the coating quality of the weld part will be greatly reduced. In a short period of time, generally 2 to 3 years, the weld part will start to peel off the paint, and the rust stains will be exposed. The surface of the main body has been treated by sandblasting, and the quality of the paint is still very good, so the life of the paint at the weld and other parts of the paint is not equal

The user has to stop working to repair and repaint the storage tank (cabinet), which increases the cost of use and produces adverse social impacts
