单体液压支柱属于煤矿单体支护设备,主要用于普采工作面的顶板支护和综采工作面的端头支护。本文针对现有单体液压支柱缺少突然来压的过载保护,在冲击载荷下容易出现涨缸、弯曲破坏的普遍问题,设计了一种新型抗冲击式单体液压支柱,并对其抗冲击性能进行分析。研究表明,与现有单体支柱相比,该新型支柱可大幅提高工作安全性能,同时可有效降低自身重量,为新型安全、轻量化单体液压支柱的设计提供参考。 The single hydraulic prop belongs to the coal mine single support equipment and is mainly used for the roof support of the general mining face and the end support of the fully mechanized mining face. In this paper, the existing single hydraulic props lack of sudden pressure overload protection prone to rise under the impact load cylinder, bending damage of the universal problem, the design of a new type of impact-resistant hydraulic props, and its impact resistance Analyze. The study shows that compared with the existing single props, the new props can greatly improve the work safety performance, meanwhile, the utility model can effectively reduce the weight of the props, thereby providing reference for the design of a new type of safe and lightweight single hydraulic prop.
