Crossing frame safety evaluation method, device and equipment and readable storage medium

The invention provides a spanning frame safety evaluation method, device and equipment and a readable storage medium, and the method comprises the steps: obtaining the length of a target cable and the vertical height difference between the top of a spanning frame and the target cable, and enabling the spanning frame to be located between the two ends of the target cable in the horizontal direction, and to be located below the target cable in the vertical direction; according to the quality of the crossing frame, the linear density of the target cable, the length of the target cable and the vertical height difference between the crossing frame and the target cable, estimated impact force is obtained through calculation, and the estimated impact force is used for predicting the maximum impact force on the crossing frame when the target cable breaks and falls, so that constructors can evaluate the safety of the crossing frame. According to the application, the maximum impact force caused to the crossing frame wh
