POWER DRIVE DEVICE OF CONCRETE PUMPING EQUIPMENT AND CONCRETE PUMPING EQUIPMENT

摘要

Disclosed in the present invention is a power drive device of a concrete pumping equipment, which comprises a first power source (1), a second power source (2), a first hydraulic pump (3), a hydraulic motor (6), a transmission casing (7), and a second hydraulic pump (8). The first power source (1) is drivingly connected to a first power input end of the transmission casing (7) through the first hydraulic pump (3) and the hydraulic motor (6), and the second power source (2) is drivingly connected to a second power input end of the transmission casing (7). The power output end of the transmission casing (7) is drivingly connected to the second hydraulic pump (8). The second hydraulic pump (8) hydraulically drives a working component (14) through a hydraulic drive pipeline (16), wherein an oil outlet of the first hydraulic pump (3) is hydraulically connected to the hydraulic drive pipeline (16). The power drive device can improve the pumping performance and the working condition adaptability of the concrete pumping equipment, thereby realizing the higher economic benefit.
