[0023] The utility model is further described with reference to the accompanying drawings.

[0024] As shown in the figure, an electric grease pump ground oil replenishing device includes a base plate 1, and lifting cylinders 6 are provided at both ends of the base plate 1. There are two lifting cylinders 6, which act synchronously. A lifting frame 7 is installed at the piston rod end of the lifting cylinder 6, and an electric grease pump group 8 is connected to the bottom of the lifting frame 7. One end of the electric grease pump group 8 is connected to an oil suction pipeline 9, and the other end is connected to an oil replenishing pipeline 16. The end of the oil suction pipeline 9 is connected to an oil scraper plate 10, and the oil scraper plate 10 is provided with an air charging pipeline and an exhaust valve. An auxiliary bracket 15 is provided at the other end of the base plate 1, and an operation control cabinet 12 is provided on the auxiliary bracket 15.

[0025] The operation control cabinet 12 is installed with electrical and pneumatic components. The cables and air pipes in the cabinet are led out of the cabinet and are respectively connected to the air circuit interface, power interface and air source interface of the corresponding motor junction box, cylinder and oil scraper pan. The outer wall of the cabinet is installed with electrical control buttons and manual air circuit valves to ensure the normal operation of the entire ground oil replenishing device.

[0026] The bottom plate 1 is provided with a support seat 2, a lifting lug 3, an oil drum pressing plate 4, and a roller 5 for facilitating the movement of the oil drum.

[0027] There are an air charging pipeline and an exhaust valve on the oil scraper 10. The air charging pipeline is used when the oil scraper is separated from the barrel, and the exhaust valve is used to remove the air in the barrel when the oil scraper initially enters the grease barrel.

[0028] A drag chain 11 is installed on the auxiliary bracket 15, and the other end of the drag chain 11 is installed on the lifting frame 7. It is used to ensure that the inflation pipe of the oil scraper plate 10, the oil replenishing pipeline of the electric grease pump, and the motor cable can be arranged neatly without interweaving or entanglement when the lifting frame 7 moves up and down, thereby reducing friction and safety hazards.

[0029] This device is used to extract grease from a standard grease barrel and add it to the lubricating grease tank of a grease truck or the grease tank of other lubricating equipment.

[0030] The specific workflow is as follows:

[0031] Preparation before operation: Connect the operation control cabinet 12 to the power supply and gas source, turn on the power switch and wait for use.

[0032] Barrel changing work: turn the corresponding hand-turned valve to raise the lifting cylinder 6, drive the lifting frame 7, electric grease pump group 8, and oil scraper plate 10 to the highest position (i.e. barrel changing position), place the standard 170Kg grease barrel at a suitable position on the bottom plate 1, and use the oil barrel pressing plate 4 to fix the bottom edge of the outside of the oil barrel and make it concentric with the oil scraper plate 10.

[0033] The scraper plate 10 enters the barrel to work: open the exhaust valve on the scraper plate 10, operate the hand valve to lower the scraper plate 10, wait until the scraper plate 10 contacts the grease in the grease barrel, and when the grease flows out from the exhaust valve, close the hand valve, the scraper plate 10 stops moving, and close the exhaust valve at this time.

[0034] Oil replenishment work: connect the oil replenishment pipeline 16 to the lubrication tank that needs oil replenishment, close the motor switch, make the electric lubrication pump group 8 work, and turn the corresponding hand-turned valve at the same time. The electric lubrication pump group 8 and the oil scraper plate 10 will move down accordingly. After completing the oil replenishment work, close the motor switch and the hand-turned valve.

[0035] After the oil filling is completed: turn the corresponding hand-turned valve to lift the lifting frame 7 and the oil scraper plate 10, and at the same time inflate the space between the oil scraper plate 10 and the grease barrel to facilitate the separation of the oil scraper plate 10 and the grease barrel. After the grease barrel is separated from the oil scraper plate 10, close the hand-turned valve to stop the oil scraper plate 10 from moving, and stop supplying air to the lower part of the oil scraper plate 10. At this time, remove the old grease barrel and replace it with a new one for continued oil filling, or when the oil filling is completed, lower the lifting frame 7 and the oil scraper plate 10 to the lowest position, turn off the power supply and air source, and the oil filling work is completed.
