An automatic sand blasting and derusting device

Abstract

The invention relates to an automatic sandblasting and derusting device; two support plates are in the shape of a horseshoe, and a gear ring and a reinforcing ring are fixed on the inner side of one support plate; On the arc, the inner guide wheels are evenly distributed on the arc of the lower part of the support plate; the ring gear and the reinforcing ring are concentric with the outer guide wheel and the inner guide wheel, and the direction and position of the opening of the support plate are the same; the arc is the same as the outer guide wheel and The inner guide wheel is evenly distributed and the two arc plates are connected as a whole; the motor is fixed on one side of the arc plate, and one end of the transmission shaft passes through the arc plate to connect with the outer drive gear; the two arc plates are snapped into the outer guide wheel In the groove of the guide wheel and the inner guide wheel, the driving gear meshes with the ring gear, and the two swing spray gun components are symmetrically fixed on the swing installation component through the swing support seat; The quality requirements of the construction were met, and the original operating time was reduced by half.

Description

technical field [0001] The invention relates to an automatic sandblasting and derusting device used in the pipeline repairing process. Background technique [0002] At present, no matter on land or in the ocean, after the welding construction of the pipeline, the joint part needs to be coated and repaired. In the joint filling process, the first process is to derust the outer surface of the pipeline within the joint joint range, and it is required to meet the corresponding standard level. [0003] In foreign countries, the technology of automatic sandblasting and rust removal has been relatively mature and widely used. In China, there are only few reports and similar one or two patents. So far, there is no automatic sand blasting and derusting device, and the manual derusting method of hand-held spray guns is still used. harm. If quartz sand is used as the rust removal medium, dust clusters will inevitably be produced to pollute the environment, and the scattered quartz s...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the existing patents and reports that the method of "single track side placement" is adopted, which is similar to the general automatic welding method, and it is a single-head device with low efficiency. It is very difficult to realize double-head

More importantly, there is still no product that can be applied in actual production, and it is only at the stage of experimental exploration
