The dynamic analysis model of the falling process of the counterweight frame during the collapse process of the bucket wheel stacker and reclaimer of the coal-fired power plant is established.Considering the movement and stress of the counterweight frame, the kinematic equations and dynamics of the counterweight frame are given Equation, the force and its variation of the diagonal tie rod and the front hinge supporter are calculated, the impact of the counterweight frame on the overall stability of the bucket elevator is evaluated, the conclusion is the analysis and identification of the accident, and the improvement of such products Design provides a theoretical basis
