Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for fully mechanized mining equipment, specifically a portable high-efficiency refueling machine for use in underground coal mines. Background Technology

[0002] During the critical installation and withdrawal phases of fully mechanized coal mining faces, trackless rubber-tired vehicles, as core transportation equipment, need to frequently travel back and forth in the roadways. Their hydraulic systems, transmission mechanisms, and bearings, among other key components, require lubrication 2-3 times per shift due to continuous high-load operation. Currently, the industry generally relies on traditional manual refueling methods, which have the following problems: they require multiple people to work together, are time-consuming and labor-intensive, have low refueling efficiency, affect construction progress, and are prone to grease spillage, polluting the underground environment. Therefore, this application proposes a portable, high-efficiency refueling machine for underground coal mines to solve these problems. Utility Model Content

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figure 1 As shown, this utility model provides a technical solution: a portable high-efficiency refueling machine for underground coal mines, including a motor 1, a coupling 2, and a gear pump 3. The motor 1 has a power of 4kW. The motor 1 and gear pump 3 are mounted on a base 9, and a switch for controlling the motor 1 is installed on the base 9. The motor 1 is connected to an underground power supply. The output shaft of the motor 1 is connected to the gear pump 3 via the coupling 2. Both the pump inlet and outlet ends of the gear pump 3 are connected to connecting pipes 4, and the connecting pipes 4 at the pump inlet and outlet ends are respectively connected to an oil inlet pipe 5 and an oil outlet pipe 6. The lengths of both the oil inlet pipe 5 and the oil outlet pipe 6 are greater than 2m. Both the oil inlet pipe 5 and the oil outlet pipe 6 are rubber hoses. The oil inlet pipe 5 is connected to an oil tank 8, and the oil outlet pipe 6 is connected to a refueling nozzle. For nozzle 7, insert the connector at the end of the inlet pipe 5 into the outlet of the oil tank 8, remove nozzle 7 from the suspension frame 10, and vertically insert its conical sealing nozzle into the oil filling port of the trackless rubber-wheeled vehicle. Press the switch to start the motor 1. The output shaft of the motor 1 drives the gear pump 3 through the coupling 2. The grease in the oil tank 8 is pressurized by the gear pump 3 through the inlet pipe 5 and output at a flow rate of 15-20L / min. It is then delivered to nozzle 7 through the outlet pipe 6, thus adding grease to the oil tank of the trackless rubber-wheeled vehicle. The suspension frame 10 is installed on the base 9, and the hanging hole on nozzle 7 is compatible with the hook at the top of the suspension frame 10. No more than the oil filling port of the trackless rubber-wheeled vehicle's oil tank. This makes it easy to hang and store nozzle 7 when not in use.

[0018] The operational steps for this application are as follows:

[0019] Insert the connector at the end of the inlet pipe 5 into the outlet of the oil tank 8. Remove the oil gun 7 from the suspension frame 10 and vertically insert its conical sealing nozzle into the oil filling port of the trackless rubber-wheeled vehicle. Press the switch to start the motor 1. The output shaft of the motor 1 drives the gear pump 3 through the coupling 2. The grease in the oil tank 8 is pressurized by the gear pump 3 through the inlet pipe 5 and output at a flow rate of 15-20L / min. It is then delivered to the oil gun 7 through the outlet pipe 6, thus adding the grease to the oil tank of the trackless rubber-wheeled vehicle.
