When oil needs to be supplied, a proper pipeline interface is installed on the oil delivery pipe 520 and is aligned with the oil cavity, oil is extracted by driving the oil supply pump 510, at the moment, the controller 400 transmits a signal to the control valve 530, the control valve 530 is powered on to open the oil delivery pipe 520, and the oil can quickly flow to the oil cavity to finish oil supply.

Referring to fig. 2 and 5, in some embodiments of the present application, the oil supply unit 500 further includes a relief valve 540, a pressure reducing valve 550, and a pressure sensor 560. Relief valve 540, pressure reducing valve 550, and pressure sensor 560 are provided in oil delivery pipe 520. One end of the relief valve 540 communicates with the oil delivery pipe 520, and the other end communicates with the oil tank 100 through the oil pipe. Pressure relief valve 550 is located between control valve 530 and relief valve 540. A pressure sensor 560 is provided between the pressure reducing valve 550 and the control valve 530.

Specifically, the overflow valve 540 may be of the type: RV 1-10V-S-0-3/3.5. The pressure relief valve 550 may be of the type: PRC06-E-, 5-00-B, the working pressure can be adjusted manually. The pressure sensor 560 may be of the type: PR130 with measuring range of 0-1.0 MPa. It should be understood that other desired types of relief valves 540, pressure relief valves 550, and pressure sensors 560 may be used. And in order to improve the degree of structural integration, the control valve 530, the relief valve 540, the pressure reducing valve 550, and the pressure sensor 560 may be arranged together to form a valve block.

Through setting up overflow valve 540, can now the fluid upper limit of fuel feeding, exceed the upper limit after, fluid just can flow back through overflow valve 540. The rest oil passes through the reducing valve 550 and the pressure sensor 560 in sequence, the oil pressure of oil supply can be adjusted manually by the reducing valve 550 so as to meet the oil supply requirement, and the oil pressure of the oil pressure can be monitored in real time by the pressure sensor 560. Meanwhile, the pressure sensor 560 may communicate with the controller 400, so that the display screen 420 may display the oil of the oil in real time. When the pressure sensor 560 detects that the oil pressure exceeds the set value, the controller 400 can directly power off the control valve 530 and activate the buzzer to warn when obtaining the monitoring result.

Meanwhile, a safety protection device can be additionally arranged on the oil conveying pipe 520 and can be in communication connection with the controller 400, when the controller 400 monitors that oil is too high, the safety protection device can be directly started to perform emergency pressure relief, and the possibility of damage to the oil supply assembly 500 is reduced.

In some embodiments of the present application, the oil supply assembly 500 further includes a return pipe 570. One end of the return pipe communicates with the oil delivery pipe 520, and the other end of the return pipe communicates with the oil tank 100. Specifically, the return pipe may be directly communicated with the return port of the control valve 530 to realize the oil return. In particular, when the oil feeding unit 500 is erroneously actuated, for example, when the manual hydraulic pump is erroneously touched, the oil is drawn out of the oil tank 100. At this time, since the control valve 530 is in a power-off state, the oil entering the oil pipe 520 can only enter the return pipe through the return port of the control valve 530, and then flow into the oil tank 100.

The present application further provides an oil supply apparatus.
