Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic support rod protection, in particular to a hydraulic support rod protection structure. Background Art

[0002] Hydraulic struts are based on Pascal's law, which states that in a closed liquid system, changes in pressure will be transmitted evenly to all parts of the system. When the liquid is under pressure inside the hydraulic strut, it is pushed through the piston and an equal force is generated.

[0003] However, hydraulic supports are often placed in exposed environments, which may lead to corrosion or external wear caused by other reasons, resulting in leakage, which may cause aging, damage or wear of the seals, resulting in the inability to effectively seal the liquid inside the support rod. Leakage will cause the liquid pressure to drop, reducing the stability and load-bearing capacity of the support rod, so a mechanism that can automatically clean the surface of the hydraulic support rod is proposed.
