Beschreibung
Zusammenfassung:	A multi-cylinder synchronous hydraulic control device disclosed by the present invention is composed of a high-pressure control loop and a low-pressure control loop, and the high-pressure control loop comprises a first adjusting control module, a second three-position four-way electromagnetic directional valve, a main pressure oil cylinder and a plurality of series oil cylinders, wherein the first adjusting control module, the second three-position four-way electromagnetic directional valve, the main pressure oil cylinder and the plurality of series oil cylinders are connected in sequence, and the main pressure oil cylinder and the plurality of series oil cylinders are separately connected with the second three-position four-way electromagnetic directional valve. The first adjusting control module is connected with an oil tank, the main pressure oil cylinder is connected with the adjacent oil cylinders connected in series through a first quick-change connector, the low-pressure control loop comprises a two-po
