新型码头浮式系缆装置防卡死技术分析

Stucked-avoiding technology for new floating mooring device on vertical pier

电站调峰以及泄洪导致电站下游水位短时间内大起大落,直接影响了下游直立式码头靠泊和装卸作业安全。借鉴船闸浮式系船柱原理,研究提出了适用于瞬时水位变幅的新型码头浮式系缆装置,给出了解决电站下游靠泊问题的思路和方法。为进一步验证浮式装置运行可靠性,即河道水流作用产生较大水平力情况下,浮筒如何克服阻力(防卡死)自由升降,分别对单一装置和多装置情况下受力特性进行了进一步的分析研究,提出分别增加一组防卡导轮和防卡连杆装置的方法,可有效防止浮筒运行"卡死"。本研究对该装置在实际工程中的运用打下坚实基础,并可为类似工程设计提供参考。

Drastic fluctuations of water level caused by peak regulation and flood discharge in the upstream affect directly the safety of berthing and terminal operation in the downstream vertical piers. A new floating mooring device based on the lock floating bollard provides a solution to the above problem. To verify the reliability that the mooring device can lift up and down freely under complex running resistances, this paper makes further study on the mooring device about one system and multi-system cases, and a group of guide-wheels and a linkage are proposed respectively to solve the stucking problems caused in the two cases. This study lays a solid foundation for the mooring device used in the actual project and serves as reference for similar projects as well.
