Abstract

The invention relates to a hydraulic system of a wing opening type box van, which comprises a left swing plate lifting oil cylinder, a right swing plate lifting oil cylinder and a hydraulic control mechanism controlling the left and right swing plate lifting oil cylinders, and is characterized in that: the hydraulic control mechanism comprises an oil tank, a gear pump, a motor, an overflow valve, a one-way valve, a throttling valve, a two-position two-way electromagnetic valve, a three-position four-way electromagnetic valve and a pipeline connecting the oil tank, the gear pump, the motor, an overflow valve, the one-way valve, the throttling valve, the two-position two-way electromagnetic valve, the three-position four-way electromagnetic valve. The hydraulic system is compact and reasonable in structure, simple in pipeline, low in fault rate and reliable in operation; the whole system is excellent in sealing performance and free from hydraulic oil leakage; and when the left and right swing plates descend and hydraulic oil returns back to the oil tank through the pipeline, the descending speed by regulating the latus rectum of the throttling valve.

Description

Technical field [0001] The invention belongs to the technical field of hydraulic devices for a wing-opening van, and in particular relates to a hydraulic system for a wing-opening van. Background technique [0002] With the continuous standardization of vehicle transportation methods, transportation companies in order to save transportation costs, improve economy, improve transportation and cargo handling efficiency, reduce labor intensity, save labor costs, meet high-efficiency and energy-saving requirements, and specialize and save labor for transportation vehicles. Put forward higher requirements, wing-opening transport vehicles will be more and more widely used in the future. At present, the hydraulic system of wing-opening vans mainly includes engine power take-off, multi-way reversing valve, hydraulic station and other structures. Through the multi-way reversing valve or the hydraulic control system of the hydraulic station, the lifting and lowering functions of the left an...
