Summary:The invention relates to a disassembly-free bridge crane reliability evaluation method. The method comprises the following steps: 1, establishing a standard normal distribution function f (t) of eachfault occurrence time interval X1, X2,..., Xn1 nearest to a component Q of a bridge crane; 2, evaluating the reliability life S of the component Q; 3, accumulating the use time delta t of the component Q by taking the nth component Q fault occurrence time data as a starting point; if the component Q does not fail in use and delta t is greater than 0.9 S and less than or equal to S, sending servicelife early warning information to the intelligent terminal equipment; and if the part Q breaks down or is maintained when in use, cleaning the latest continuous n times of failure occurrence time data in the step 1, and returning to the step 1 by taking the current failure occurrence time data of the part Q of the bridge crane as the nth time of failure occurrence time data Yn. By evaluating thereliability life of the com
