Pipeline internal and external wall rust removal device for construction site

Abstract

The invention discloses a derusting device for inner and outer walls of pipelines for construction sites, which comprises a bottom plate, a support rod, a top plate, a left side plate, a right side plate, a clamping device, a first motor, an inner wall grinding device, an outer wall grinding device, a first Vertical bar, horizontal bar, second vertical bar, slider, third vertical bar, waist-shaped through groove, mounting plate, third motor and second connecting rod, the present invention is provided with inner wall grinding device, and inner wall grinding device comprises rotating shaft , hollow sleeve, fixed rod and first connecting rod, through the cooperation of the above parts to grind the inner wall of the pipeline, the first grinding steel wire is always close to the inner wall of the pipeline to ensure the thoroughness of grinding and derusting. There is an outer wall grinding device, the second The three motors, the third connecting rod, the third vertical rod and the horizontal rod, through the cooperation of the above parts, can grind the outer wall of the whole pipeline in all directions, the grinding is sufficient, the effect is good, and the efficiency is high. The inner and outer walls are polished at the same time, which improves the work efficiency and reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to a derusting device, in particular to a derusting device for inner and outer walls of pipelines used in construction sites. Background technique [0002] With the development of the economy, the construction industry also has great development opportunities along with the development of the economy. In the production and construction process of the existing construction industry, more and more pipelines are used and maintained, and various pipelines are often used in construction sites With the passage of time, the inner and outer walls of many iron pipes will increase with the increase of service time, which will increase a lot of impurities, dirt or rust. The generation of these pollutants affects the service life and quality of the pipeline. Currently, in construction During construction, hand-held angle grinders are still used to remove rust on the surface of metal profiles. This manual rust removal method has disadvantages ...

[0002] With the development of the economy, the construction industry also has great development opportunities along with the development of the economy. In the production and construction process of the existing construction industry, more and more pipelines are used and maintained, and various pipelines are often used in construction sites With the passage of time, the inner and outer walls of many iron pipes will increase with the increase of service time, which will increase a lot of impurities, dirt or rust. The generation of these pollutants affects the service life and quality of the pipeline. Currently, in construction During construction, hand-held angle grinders are still used to remove rust on the surface of metal profiles. This manual rust removal method has disadvantages such as low work efficiency, high labor intensity, high damage rate of machines and tools, and poor safety performance. In the process of rust removal, the most commonly used method is to manually use wire brushes to remove rust. This method relies purely on manpower, has low efficiency, poor rust removal quality, high labor intensity, and cannot perform internal and external grinding and rust removal at the same time. Low
