Title:
HYDRAULIC SYSTEM FOR ADJUSTING AND CONTROLLING LOADING AND UNLOADING PLATFORM
Document Type and Number:
WIPO Patent Application WO/2023/070896
Kind Code:
A1
Abstract:
A hydraulic system for adjusting and controlling a loading and unloading platform. The hydraulic system comprises: an actuating module (1) for driving the movement of a loading and unloading platform, an oil supply module (2) for providing power for the actuating module (1), and an adjusting and controlling module (3), which is arranged between the oil supply module (2) and the actuating module (1), wherein the actuating module (1) comprises a lifting cylinder (11), which is connected to the loading and unloading platform and is used for driving the lifting of the loading and unloading platform, and an adjusting cylinder (12) for adjusting the angle of the loading and unloading platform; the adjusting and controlling module (3) comprises an oil supply pipeline (35) and an oil return pipeline (36), both of which are connected to the oil supply module (2), a first connecting pipeline (4, 34), which is connected to the lifting cylinder (11), and a second connecting pipeline (5, 34), which is connected to the adjusting cylinder (12); and both the first connecting pipeline (4, 34) and the second connecting pipeline (5, 34) are in communication with the oil supply pipeline (35) and the oil return pipeline (36). The hydraulic system further comprises a switch assembly (6) and a controller for controlling the operation of the switch assembly (6), so as to adjust the opening and closing of the oil return pipeline (36), the first connecting pipeline (4, 34) and the second connecting pipeline (5, 34).
