“…The effect of cable retracting and retracting is not only affected by its structure and size design, but also affects the overall structure size and use function of cable retracting and retracting device. With the continuous development of shipping industry, the load capacity of port ships increases, and the long-distance transportation of port machinery is a trend of future development [1][2][3]. As an important bearing part of the port machine, the reliability of its structural design affects the safe operation of the port machine.…”

Single row cable reels are often used in the study of cable reels by heavy port machinery equipment, but there are problems of less cable capacity and larger circumferential space. In the design of the traditional heavy machinery cable drum design concept principle as the basis, on the basis of the drum structure optimization and strength check. According to the design of cable parameters, it is concluded that the winding of drum occupies less space, the cable is arranged in a regular order and can accommodate a large amount of cable. In this paper, Ansys Workbench is used for structural mechanical analysis of the drum body, and the final results show that the maximum stress of the drum under the working load is far less than the allowable stress value. By analyzing the mechanical state under the working condition, the effect of cable capacity increase is obvious, and the relative mass is reduced, and the stability of the drum structure meets the requirements.

Objective: As a carrier, bridge cranes are widely used in port cargo handling. Due to the structure of the crane itself, the load inevitably produces displacement deviation and lifting weight swing. Therefore, the optimization investigation of the bridge crane control system is carried out to guarantee the fast and secure operation of the crane. Method: According to the characteristics of bridge cranes, combined with the experience of on-site operating staff, the fuzzy rules that meet the working conditions of the site are designed by using the advantages of fuzzy PID (Proportion-Integration-Differentiation) control algorithm without relying on an accurate mathematical model, to set the parameters of the fuzzy PID controller. The speed control technique of frequency converter is adopted to design the system to improve the safety of the overall system. Results: The results show that the adjustment time of the swing angle of crane weight of the traditional PID control requires 6.79s, and the maximum swing angle of crane weight is 0.039rad, and the adjustment time under the fuzzy control is 4.89s, and the swing angle of crane weight is 0.013rad. The fuzzy PID controller surpasses the traditional PID controller in the positioning accuracy. It is not sensitive to changes in the internal parameters of the system. Also, it has strong adaptability to changes in operating conditions. The swing angle of crane weight is smaller, which further improves the robustness. The vector frequency conversion speed control has a more precise control effect on the speed and running track of the operating mechanism of the bridge crane. This method can be applied to the automatic operation mechanism of bridge cranes and achieve good control performance. Conclusion: The conducted optimization investigation of the bridge crane control system makes the control system flexible, simple and robust, providing important theoretical support for related explorations.
