As an important part of the shearer, the performance of traction hydraulic system not only affects the life of shearer haulage unit, but also relates to the work results of shearer, influencing its operating efficiency. The design of the hydraulic system of traction was completed. The system schematic was drawn. From the aspects of high?voltage protection, overspeed protection and differ?ential non?slip protection, low?voltage protection and over?zero protection, protection design for the hydraulic system was completed. Based on analysis and calculation, the parameters of the main components of the hydraulic system were identified, the selection of the main components was completed. The research provides a technical basis for the design of shearer traction hydraulic system.
