ABSTRACT
The higher the degree of automation of the hydraulic forklift, the less labor required in construction, and the production efficiency will be greatly improved. With the growth of the economy and the advancement of science and technology, hydraulic forklifts have been more widely used in industrial production and material fields. Therefore, the research and optimization of hydraulic forklift engineering devices is a very important work. Under this industrial demand and research background, designing a hydraulic forklift working device with simple structure, convenient control, economical and durability has very important application value and research. Meaning, the hydraulic forklift working device finally designed in this subject mainly includes main structures such as body, tilting hydraulic cylinder, gantry, lifting hydraulic cylinder, tilting hydraulic cylinder, etc. It has high operating efficiency, stable structure, small space occupation, and economic benefits. big.
This topic in the research process, the design of the hydraulic forklift working device of the overall scheme, including listing the main content of the study, the main design parameters and the overall scheme of the design. Also designed the hydraulic forklift working device lifting system and hydraulic forklift tilt system, mainly including the design and calculation of hydraulic cylinder. Finally, the hydraulic system of the working device of the hydraulic forklift truck is studied, including the design of the hydraulic circuit of the lifting system, the design of the hydraulic circuit of the tilt system, the design of the working order table of the hydraulic system and the design of the working principle of the hydraulic system. It also includes calculation and selection of oil pump and motor, selection of coupling, selection of control valve, selection of oil return filter, hydraulic pipeline design, hydraulic tank design and hydraulic system temperature checking.
