| Abstract: | Taking the large span tower group project of the second crossing of the 500 kV Jiangyin Yangtze River as the background，the structure and function of SCQ90 operator transport elevator was introduced in this paper，and the structural strength and stability of the guide rail of the non-counterweight medium speed inclined elevator was mainly studied.The whole length of the guide rail is 332 m，including 227 sections of the standard guide rail frame.Conventional finite element method could not get the accurate result in a short time because of the complex structure，which is not good for fast iteration and check，and even delays the engineering cycle.Therefore，a fast calculation method for the structural strength of the elevator guide rail was proposed by combining the analytic method and structured strategy.The research showed that this calculation method can accelerate the structure calculation of the guide rail device significantly，and had ideal calculation accuracy，which was worth popularizing in actual engineering.Combined with the research object，this paper got the conclusion of the structural strength and stability of the elevator guide rail，and put forward the corresponding engineering improvement suggestions. |
