[0002] Hydraulic props are retractable support devices that utilize fluid pressure to provide support and unload loads. They are mainly composed of core components such as the prop body, piston, and valves. Driven by high-pressure emulsion supplied by a pump station, they are suitable for roof support in underground working faces. During the production overload of hydraulic props, the exterior of the steel pipes used to produce the props needs to be polished for subsequent rust prevention and painting. Iron filings are generated during the polishing process, and these filings can cause environmental pollution in the workshop. Therefore, it is particularly necessary to develop a hydraulic prop polishing device that reduces the amount of iron filings falling into the workshop and keeps the workshop clean.

When it is necessary to clean the iron filings on the support platform 1, the electromagnet 21 is turned off to facilitate the removal of the iron filings that have fallen on the iron plate 20.

[0026] The specific working process is as follows: The column to be polished is placed between the drive wheel 10 and the rotating shaft 2.
