Application of gyration support in trick rotating device

为解决轨道系统中变向旋转装置金属结构变形大、旋转中心定位困难的问题,以柘溪水利发电厂过坝滑道设备改造工程为例,简要分析了铁路系统和矿山领域中的轨道旋转装置,将回转支承成功的运用于柘溪水利发电厂过坝滑道设备的轨道旋转装置中。针对轨道旋转装置设备金属结构运行时的力学性能,提出了相应的基本假设条件,从强度和刚度两个方面对新旧旋转装置的金属结构进行了静力学结构分析,得出了将回转支承运用于新旋转装置后的新旧旋转装置金属结构的应力和挠度曲线;最后,根据基本假设条件和现场的安装情况对旋转装置金属结构和回转支承的安装提出了基本原则,充分保证了旋转装置在使用过程中,其金属结构按照新设备的力学模型运行。研究结果和现场运行检测记录表明,回转支承的运用对轨道旋转装置金属结构的强度和刚度有明显改善。

In order to solve the problem that the metal structure of converting and rotating devices have large deformation and the center of gyration is hard to position,founded on the Zhexi Hydroelectricity station dam passing slide device rebuilding project, the track rotating device in the railway and mine was briefly analyzed, thc gyration support mechanism was used on the track rotating device of Zhexi Hydroelectricity station dam passing slide device successfully. Aiming at the metal structure mechanical property of the track rotating devices when the devices were working, the basic assumptions were proposed, the results of stress and defection curve of new and old devices was gotten from the static structure analysis in strength and stiffness. Finally, according to the basic assumption and the site installation situation, the basic principle of gyration support installation was proposed to make sure metal structure of the rotating device working conform to the mechanic model of new devices. The results and the site operation detection both indicate that the gyration devices improve the track strength and stiffness significantly.
