[0023] Reference Figure 1 and Figure 2 , walking wheels 5 are provided at the four corners of the bottom of the trolley box 1, and the walking wheels 5 can drive the application to walk and move to the required position, and can be adjusted accordingly according to the position of the coal mine machinery and equipment. A push-pull rod 2 is installed on one side of the top of the trolley box 1, and a cable hook 3 is set on one side of the push-pull rod 2. It should be noted here that the push-pull rod 2 of the application is used to assist the movement of the trolley box 1, and the cable hook 3 is used to carry the oil outlet pipe, oil suction pipe and cable. When not in use, the oil pipe and cable are neatly hung on the cable hook 3 for easy use next time, which can prevent the oil outlet pipe and oil suction pipe from being scattered on the ground or placed messily on the trolley.

[0024] It should be noted that the trolley box 1 of the present application is 600mm long and 30mm wide, and is welded from iron sheets and angle irons. It is the carrier of the entire refueling device. The size of the trolley can be determined according to actual conditions. The present application only gives one implementation method; the push-pull rod 2 is welded into a "U" shape by three steel pipes, and then the push-pull rod 2 is welded to the top side of the trolley box 1.

[0025] Reference Figure 1 and Figure 2 An electric motor 6, a coupling assembly 11 and a gear pump 4 are arranged on the top of the trolley body 1, wherein the electric motor 6 is a 380V and 1.5kW three-phase asynchronous motor, which is the power source of the equipment; its output end is connected to the gear pump 4 through the coupling assembly 11, and the coupling assembly 11 is located between the electric motor 6 and the gear pump 4. The gear pump 4 is a conventional equipment in the mechanical field. This application serves to transfer oil. This application does not improve it, so it will not be described in detail.

[0026] Furthermore, an oil outlet interface 7 and an oil suction interface 8 are provided on the gear pump 4, wherein the oil outlet interface 7 is connected to the oil outlet pipeline, and the oil suction interface 8 is connected to the oil suction pipeline. The oil outlet pipeline can be connected to the oil tank of the mechanical equipment, and the oil suction pipeline can be connected to the oil storage barrel. The AC motor is used as the power source, and the gear pump 4 is driven to rotate through the coupling assembly 11, so as to achieve the purpose of extracting or pumping in the oil.

[0027] Furthermore, a safety valve 9 and a pressure gauge 10 are also provided on the gear pump 4, wherein the safety valve 9 can be installed at the oil outlet interface 7 and the oil suction interface 8, and its pressure range is 0--3MPA, which plays a protective role, and together with the pressure gauge 10, plays a role of oil pressure protection.

[0028] Reference Figure 1 and Figure 2 The coupling assembly 11 includes a coupling cover and a coupling arranged inside the coupling cover. The coupling cover is used to protect the coupling. At the same time, the coupling cover can be removably fixed to the trolley box 1 by bolts or pins to facilitate subsequent disassembly and replacement. It connects the motor and the gear pump to play a role in power transmission and protection. The coupling is used to transmit the power of the motor 6 to the gear pump 4.

[0029] The specific operating principles of this application are as follows:

[0030] When in use, the staff can move the trolley box 1 to the vicinity of the equipment oil tank according to the needs of the mechanical equipment (which may be a coal mining machine, a tunneling machine, a shield machine, etc. that needs to be refueled), and then tightly connect the oil outlet pipe with the oil outlet interface 7, and a sealing ring can be added at the connection to ensure the sealing effect between the two; then tightly connect the oil suction pipe with the oil suction interface 8, and similarly, a sealing ring can be added at the connection between the two; then connect the oil outlet pipe to the mechanical equipment oil tank, and the oil suction pipe to the oil storage barrel. The oil storage barrel does not need to be adjusted in position, and only the length of the oil outlet pipe and the oil suction pipe needs to be extended. In this way, it is only necessary to move the trolley box 1, and then use the AC motor 6 as the power source to drive the gear pump 4 to rotate through the coupling, so as to achieve the purpose of extracting or pumping oil.
