一种矿用单体液压支柱
摘要：
本发明涉及单体液压支柱技术领域，公开了一种矿用单体液压支柱，包括缸体和底座，所述的缸体内部嵌套有活柱，缸体的上端设有手把体，所述的活柱外表面滚压有一层不锈钢层，所述的不锈钢层的外侧还设有喷涂有耐磨层，所述的耐磨层为喷涂聚甲醛层。本发明活柱的外侧首先滚压有一层不锈钢层，在不锈钢层的外侧喷涂有耐磨聚甲醛层，当活柱暴露在外收到冲击碰撞时，能够避免活柱的损坏，外部的耐磨层和不锈钢层损坏后可以通过维修更换，大大节约了成本，提高工作效率。
摘要（英）：

The invention relates to the technical field of individual hydraulic props and discloses a mining individual hydraulic prop which comprises a cylinder and a base. A plunger is embedded in the cylinder, the upper end of the cylinder is provided with a handle, the outer surface of the plunger is provided with a stainless steel layer by rolling, and the outer side of the stainless steel layer is coated with a wear-resistant layer which is a polyformaldehyde layer. Since the outer side of the plunger is provided with the stainless steel layer by rolling, and the outer side of the stainless steel layer is coated with the wear-resistant layer, the plunger exposed outside can be protected from damages in collision, the outer wear-resistant layer and the stainless steel layer can be maintained andreplaced after being damaged, cost is greatly saved, and operation efficiency is improved.
