多绳摩擦提升机快速卡绳装置的研究及应用

Research and Application of a High-Speed Clip for Multi-Rope Friction Hoist

针对目前卡绳装置承载能力低、卡绳时间长等不足,结合义煤集团千秋煤矿新副井多绳摩擦提升机换绳的实际工况,以现有快速卡绳装置为基础,研制了满足千秋煤矿新副井换绳要求的快速卡绳装置。对卡绳装置关键部件进行有限元分析,得到了内部应力分布规律,进一步优化了结构。为了验证快速卡绳装置的可靠性,在液压试验台上开展试验研究,试验结果满足设计要求;现场应用表明:快速卡绳装置具有承载能力大、卡绳效率高、工作可靠等优点,满足矿井生产高速化、大型化的要求。

Aiming at the shortages of low bearing capacity and long time clipping to the existing clips and combining with the actual working conditions of changing rope for multi-rope friction hoist in auxiliary shaft of Qianqiu Coal Mine, a new-type high-speed clip on the basis of the existing clips is designed which meets the requirements of changing rope in Qianqiu Coal Mine. The key parts of the new-type clip are analyzed based on Finite Element Analysis, and the principle of inner stress distribution is obtained, so that its structure is optimized further. In order to verify the reliability of the new-type clip, some experiments are carried out on the hydraulic test platform, and the experimental results meet the design requirements. The field application also indicates that the new-type clip provides the advantages of large bearing capacity high clipping efficiency and reliability, etc. Therefore, it can satisfy the requirements of mining development towards high- speed and large-scale.
