Design Of Hydraulic Winch Based On The Two Adjusting Technology

Abstract This design is using advanced secondary regulation technology, the design of hydraulic winch, hydraulic winch as a core member of the heavy machinery, the in various important places in plays a vital role。 At home and abroad hydraulic winch of structures and manufacturing enterprises has always attached great importance to optimize the performance of the hydraulic winch, and hydraulic winch performance optimization of core is high efficiency and energy saving, today's hydraulic system of hydraulic winch efficiency is low, energy consumption is high。 Therefore, this paper, taking this as a starting point, using advanced secondary regulation technology of the hydraulic winch hydraulic system were redesigned。

First of all, this paper, by consulting relevant literature proposed this topic research background, through the understanding of the hydraulic transmission technology definition, classification and characteristics; the definition of the winch drive type and application range of interpretation; introduction of the secondary regulation technology, working principle and research status of proposed based on secondary regulation technology of a new energy-saving winch system design, outlined the topic of the research content and significance；

Secondly, through the traditional winch assembly structure scheme analysis and winch lift starting, hoisting braking, falling starting, down four working processes of brake dynamic analysis design a simple, small size, light weight and maintenance maintenance convenient hoist structure, and expounds the design of the structure of the winch some matters needing attention；

Again, according to the parameters of the task book to the winch drum, motor, brake, clutch, coupling and drive shaft for the corresponding size, torque and other design calculations, and to carry out the necessary check；

Finally, the drawworks structure design based on Design Based on secondary regulation of hydraulic winch hydraulic pressure system, and carries on the analysis and control system to carry on the analysis of the circuit of the hydraulic system, selection and calculation of main hydraulic element of the hydraulic system, list the element list。
