[0043] The hydraulic power unit 3 is connected with the hydraulic cylinder 9 through two hydraulic pipelines 2, i.e. a first branch and a second branch; the first branch is used for conveying hydraulic oil to the hydraulic cylinder 9 to execute the extension action, and the second branch is used for conveying hydraulic oil to the hydraulic cylinder 9 to execute the retraction action. Figure 5 As shown in the figure, the first branch of the hydraulic pipeline 2 is further provided with a pressure sensor 17 for detecting the pressure value in the hydraulic pipeline 2; the pressure sensor 17 is connected with the controller 1; when the pressure value is greater than the preset value, the hydraulic cylinder 9 is stopped to work, and at this time, the filling plate 10 reaches the lowest position.

[0044] In the specific embodiment, the filling plate 10 is a flat plate structure, or a "U" type structure; one end of the filling plate 10 away from the vertical plate 14 is vertically provided with a baffle 16. Figure 2 As shown in the figure, the baffle 16 is provided with an oil filling switch 11 and a full indication lamp 12; the baffle 16 is provided with the fuel filling port 13. The fuel filling port 13 is connected with the fuel tank through the fuel pipeline 4; when the oil is filled, the fuel is conveyed from the fuel filling port 13 to the fuel tank 5 through the fuel pipeline 4 under the action of the oil filling pump, so as to realize the fuel filling. The hydraulic cylinder 9 drives the filling plate 10 to ascend and descend; when the filling plate 10 is at the initial position, the filling plate 10 is perpendicular to the vertical plate 14.

[0045] In the specific embodiment, the filling plate 10 and the vertical plate 14 are respectively provided with fixed seats; the output end of the hydraulic cylinder 9 and the fixed seat on the filling plate 10 are respectively holed, and the two are fixed through a pin shaft; the other end of the hydraulic cylinder 9 and the fixed seat on the vertical plate 14 are respectively holed, and the two are fixed through a pin shaft.

[0046] In a specific embodiment, the platform structure mainly plays a role of support and load bearing, such as Figure 4 As shown in the figure, the horizontal plate 15 is provided with a lifting switch 7, and the controller 1 is connected with the lifting switch 7. The lifting switch 7 is used to generate an up signal or a down signal and transmit to the controller 1. The lifting switch 7 can be an up button and a down button, and specifically:

[0047] The down button is used to generate a down signal and send to the controller 1. After the controller 1 receives the down signal, the controller 1 controls the hydraulic power unit 3 to output hydraulic power, and at the same time, the controller 1 controls the down electromagnetic valve on the hydraulic pipeline 2 to be attracted, driving the hydraulic oil cylinder 9 to extend, so as to lower the filling plate 10 to the set position. When the filling plate 10 is lowered to the position, the limit switch 8 is opened, and the engine is prohibited to start to prevent danger.

[0048] The up button is used to generate an up signal and send to the controller 1. After the controller 1 receives the up signal, the controller 1 controls the hydraulic power unit 3 to output hydraulic power, and at the same time, the controller 1 controls the down electromagnetic valve on the hydraulic pipeline 2 to be disconnected, driving the hydraulic oil cylinder 9 to retract, so as to raise the filling plate 10 to the initial position. When the filling plate 10 is raised to the position, the limit switch 8 is closed, and the engine is allowed to start.

[0049] The filling plate 10 is rotationally connected with the vertical plate 14. Under the driving action of the extension and retraction of the hydraulic oil cylinder 9, the filling plate 10 rotates around the connection to realize the lifting action of the fuel filling port 13.

[0050] The controller 1 is also connected with a refueling switch 11. When the filling plate 10 is lowered to the position, the limit switch 8 is opened, and the engine is prohibited to start. The staff can operate the refueling switch 11 to generate a refueling signal. When the controller 1 receives the refueling signal, the controller 1 opens the refueling pump to start refueling into the fuel tank 5. As shown in the figure, Figure 7 The fuel tank 5 is provided with a liquid level sensor 6 for obtaining real-time fuel liquid level information in the fuel tank 5. The liquid level sensor 6 is connected with the controller 1. When the refueling pump is opened to start refueling into the fuel tank 5, the controller 1 can obtain the fuel liquid level value of the liquid level sensor 6 in real time and judge whether the liquid level value reaches the set value, i.e. 95% of the liquid level value. When the set value is reached, the full-filling indicator 12 is bright, the refueling is stopped, and the lifting switch 7 is operated to raise the filling plate 10. As shown in the figure, Figure 3 The vertical plate 14 is provided with a hole at the corresponding position, and the limit switch 8 is installed to detect the position of the filling plate 10. When the filling plate 10 is raised to the position, the limit switch 8 is closed, and the engine is allowed to start.

[0051] The embodiment is provided with a filling plate 10 capable of controlling ascending and descending, and a fuel filling opening 13 is arranged on the filling plate 10, one end of a fuel pipeline 4 is communicated with the fuel filling opening 13, and one end of the fuel pipeline 4 is communicated with an oil tank, so that an operator does not need to climb to the top of the mining excavator, and does not need to manually extend the oil pipeline into the oil tank filling opening, and can stand on the ground to perform fuel filling, thereby improving the safety and efficiency of fuel filling operation.
