Automatic descaling equipment for large-mouth diameter tubular structure

Abstract

The invention relates to the field of pipeline descaling, in particular to automatic descaling equipment for a large-mouth diameter tubular structure. The automatic descaling equipment comprises a wall scraping mechanism, a traveling mechanism, a first roller assembly and a second roller assembly, the wall scraping mechanism is used for scraping dirt on the inner wall of the tubular structure; thetraveling mechanism is connected with the wall scraping mechanism and used for driving the wall scraping mechanism to walk and complete scraping action; the traveling mechanism comprises a shell of acylindrical structure and a fixing shaft arranged in the shell and located on the axis of the shell, and the two ends of the fixing shaft are fixed to the two ends of the shell; the first roller assembly is arranged at one end of the fixing shaft and comprises a plurality of first rollers, the first rollers are arranged on the same circumference at equal angles relative to the axis of the fixingshaft, and the distance between each first roller and the axis of the fixing shaft is adjustable; the second roller assembly is arranged at the other end of the fixing shaft and comprises a pluralityof second rollers, the second rollers are arranged on the same circumference at equal angles relative to the axis of the fixing shaft, the distance between each second roller and the axis of the fixing shaft is adjustable, and the first roller and the second roller enable the traveling mechanism to walk along the axis direction of the fixing shaft. The automatic descaling equipment can automatically scrape dirt in tubular structures with different diameters.

Description

technical field [0001] The invention relates to the field of pipeline scale removal, in particular to an automatic scale-scraping device for large-diameter tubular structures. Background technique [0002] Pipeline refers to the device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. All kinds of pipes should be cleaned before use, and some pipes should be cleaned regularly. For the convenience of cleaning, a filter or a purge cleaning hole is arranged on the pipeline...

AI Technical Summary

Problems solved by technology

In the process of cleaning some large water pipes or other pipelines that have been put into practical use for a long time, high-pressure water washing is often used for cleaning, and for some dirt attached to the pipe wall, the nozzle cannot wash it away.
