Abstract

The invention provides an energy consumption method and device and an operation machine. The method comprises the following steps: obtaining converted electric energy, wherein the converted electric energy is generated by potential-electricity conversion of a winch system of the operation machine; under the condition that the operation machine meets the target condition, obtaining residual electric energy of the winch system based on the converted electric energy, and obtaining the target rotating speed of an oil pump motor in a hydraulic system of the operation machine and the target opening degree of a proportional overflow valve based on the residual electric energy; and after the winch system is controlled to supply power to the hydraulic system, controlling the hydraulic system to consume the residual electric energy based on the target rotating speed and the target opening degree. The invention provides the energy consumption method and device and the operation machine, which have the advantage that the residual electric energy of the winch system can be more accurately consumed by utilizing the hydraulic system of the operation machine under the condition of not additionally configuring equipment, and the input cost is lower, and the economical efficiency is better.

Description

Technical field [0001] The present invention relates to the field of construction machinery, and more particularly to an energy consumption method, device and operation machinery. Background technique [0002] Configure a work machine with a rolling system, which can be lifted or decentralized to the specified location based on demand. During the operation mechanical lifting load, the engine's engine can drive the hydraulic system to drive the rolling system to increase the load, and convert the energy generated by the fuel to the load. During the operation of the operation machine, the power can pass The rolling system is converted to power. [0003] Under some special work conditions, for example, the construction work such as subway, tunnels, and the operation machine repeats the load from a height to the lower, and the load is returned to the height and continues the above operation process. Working machine repeats the load from a height to a low, the rolling system will cont...
