Example Embodiment
[0020] The specific content of the present invention will be further described with reference to the embodiment of the gravity potential energy recovery device for the boom of construction machinery shown in the accompanying drawings.
[0021] A device for recovering gravitational potential energy of a construction machinery boom, which includes a hydraulic device that drives the boom to work, an accumulator device, and a safety protection device for a hydraulic system. The hydraulic device uses two bidirectional quantitative hydraulic pump-motors. One oil port of the two bidirectional quantitative hydraulic pump-motors is connected to the rod cavity of the boom cylinder 10 and the accumulator 9 through a connecting pipe, and the other oil port of the two bidirectional quantitative hydraulic pump-motors is connected to the boom cylinder 10 through a connecting pipe. The boom cylinder 10 is connected without a rod cavity, and the electric motor 1 drives two bidirectional quantitati...
