Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] like figure 1 As shown, it is a hydraulic lift control system for a dump truck, including a hydraulic drive system, a hydraulic lift system and a control valve group. The hydraulic drive system includes a hydraulic oil tank 1, a power unit 2, a control valve group and an oil pipe assembly. The hydraulic circuit and the hydraulic drive passage are connected to the hydraulic lift system 6 through the high-pressure oil pipe 11; an energy storage system is connected in parallel to the hydraulic drive passage, and the energy storage system includes a storage device for storing high-pressure hydraulic oil. Energy storage tank 12; wherein in the hydraulic drive system, the hydraulic oil tank 1 is connected to the input end of the power device 2 through the oil pipe 8, and the output end of the power device 2 is connected to the hydraulic oil tank 1 through the circuit ...

A dump truck hydraulic lift control system, including a hydraulic drive system, a hydraulic lift system and a control valve group, the hydraulic drive system includes a hydraulic circuit composed of a hydraulic oil tank, a power unit, a control valve group and an oil pipe assembly, and a hydraulic drive The hydraulic drive channel is connected to the hydraulic lifting system through a high-pressure oil pipe; the hydraulic drive channel is connected in parallel with an energy storage system, and the energy storage system includes an energy storage tank for storing high-pressure hydraulic oil. The invention uses the energy storage system to recycle the energy lost during the running of the vehicle, and converts it into high-pressure hydraulic oil and stores it in the energy storage tank of the energy storage system. When unloading, there is no need to start the power device, and only the energy storage system The high-pressure oil release drives the hydraulic lifting system to complete the unloading; thus, it can not only reduce fuel consumption, but also shorten the unloading time, which has the advantages of energy saving, emission reduction, operation cost reduction and economic benefit improvement.
Description
technical field [0001] The invention relates to the technical field of hydraulic control of construction machinery, in particular to a hydraulic lift control system of a dump truck. Background technique [0002] Mining dump truck is a kind of mining transport truck, which belongs to one of mining equipment. It is mainly used for rock and earth stripping and bulk material transportation in open-pit mining areas. The mining dump truck is mainly composed of frame, engine, gearbox, cab, body, front and rear axles, wheels, electrical system, steering system, lifting system, braking system, etc. All need to start the power unit to generate high-pressure oil in the hydraulic system, drive the lifting system through the high-pressure oil, and then unload the cargo. The process of preparing the dump truck for unloading takes about 30 to 35 seconds each time. If it is calculated by unloading 50 times a day, it takes half an hour to prepare for unloading, and this part of the time is ...
