Embodiment Construction

[0021] The oil-electric dual power driving device of the hydraulic lifting system of the aerial work vehicle involved in the present invention has two power sources, that is, the first power source is the engine, and the second power source is the motor 10 . Starting from the first power source, it is sequentially input into the gearbox 1, the power take-off 3, the universal joint transmission device, and the dual power coupling device. The dual power coupling device also includes a second power source. The dual power coupling device can realize two Two power sources are synthesized, that is, the second power source is mixed with the input first power source and then output to a hydraulic pump 9 only through one output port.

[0022] figure 1 It is a schematic diagram of the structure of the oil-electric dual-power drive device of the hydraulic lifting system of the aerial work vehicle. Its basic structure is: the power output from the engine (not shown in the figure), throug...

Abstract

The invention discloses an oil-electricity dual-power driving device of a hydraulic lifting system of an aerial operation car, which comprises a gearbox, a force extractor, a universal joint transmission device and a dual-power coupling device sequentially input by a first power source. The dual-power coupling device also comprises a second power source, and the second power source and the first power source are merged and output to the same hydraulic pump. Compared with a traditional oil-electricity dual-power driving hydraulic lifting system of the aerial operation car, the invention saves one hydraulic pump and can achieve high selection possibility of system structures and control modes. Accordingly, the invention can provide a wider design space for further optimizing the energy-saving environmental-protection performance of the hydraulic lifting system of the aerial operation car.

Description

technical field [0001] The invention relates to a construction machine, in particular to an oil-electric dual power drive device for a hydraulic lifting system of an industrial control operation vehicle. Background technique [0002] At present, most of the commonly used hydraulic lifting systems for aerial work vehicles use the original vehicle diesel engine as the power source, and drive the hydraulic pump through the gearbox power take-off and cardan shaft to make the hydraulic lifting system work. This power-driven working mode has the problems of high engine noise and serious exhaust pollution, which has a great impact on the environment. During live work at heights, if the engine is required to remain idle for safety, its fuel economy is even worse. In order to achieve low-noise and zero-emission high-altitude operations, a Japanese company has developed and produced an aerial work vehicle that uses an oil-electric dual-power drive hydraulic system. The motor is driv...
