And the hydraulic control assembly comprises an electromagnetic directional valve 210, the electromagnetic directional valve 210 is respectively communicated with the execution device 300 and the oil pump 130, and the electromagnetic directional valve 210 is used for controlling the forward flow and the return flow of the oil path.

The specific connecting oil way of the hydraulic station is as follows: oil enters the oil pump 130 from the oil outlet of the oil storage container 110, the oil pump 130 pumps the oil into a pipeline, enters one side of the cylinder body of the execution device 300 through the electromagnetic directional valve 210, flows through the electromagnetic directional valve 210 from the other side of the cylinder body, and finally enters an oil return pipeline to be communicated with an oil return port of the oil storage container 110.

The two sides of the cylinder of the actuating device 300 are communicated with different oil paths, and the oil paths on the two sides of the cylinder are respectively communicated with the electromagnetic directional valve 210, so that the flow direction of oil in the cylinder is changed by changing the working state of the electromagnetic directional valve 210. Specifically, the electromagnetic directional valve 210 is a two-position four-way electromagnetic valve, and is respectively communicated with oil passages on two sides of the cylinder, the oil pumping direction of the oil pump 130 and the oil return direction of the oil storage container 110, when the electromagnetic directional valve 210 is in the first working position, the oil pumping direction of the oil pump 130 is communicated with one side of the control cylinder pushed out, the oil return is communicated with one side of the control cylinder pushed back, at this time, the oil pump 130 can assist in pushing the execution device 300 to advance, when the electromagnetic directional valve 210 is in the second working position, the oil pumping direction of the oil pump 130 is communicated with one side of the control cylinder pushed back, the oil return is communicated with one side of the control cylinder pushed out, at this time, the oil pump 130 can assist in pushing the execution device 300 to back.
