The main components of hydraulic support are hydraulic column, jack, roof, base, guard plate, connecting rod, valve group lock block, and electro-hydraulic control. Among them, hydraulic column is the main equipment to support the roof of coal mining working face by hydraulic principle. It has high requirements on the supporting force and anti-corrosion ability of hydraulic column. When the surface of the coating of the hydraulic column of the support is corroded and chromium is removed, the hydraulic column will leak, seep, and fail to maintain pressure.

At the same time, due to different manufacturers and different bracket models, the cylinder diameter of the hydraulic column is also different. In production practice, the use of convenient and universal tooling is an important factor in improving production efficiency and reducing tooling production costs. Utility Model Content
