Description

Technical Field

[0001] This utility model relates to the field of lubrication systems, specifically to an oil injection system with an automatic oil replenishment device. Background Technology

[0002] Lubrication systems, essential for all industries, play a vital auxiliary role in maintaining the operation of main equipment and ensuring production safety.

[0003] The medium in the lubrication system is lubricating oil or grease. The lubricating medium will be consumed after a period of use, and then lubricating oil needs to be added before it can operate normally.

[0004] Internationally, lubricating oil is generally packaged and transported in 180L drums. Once on-site, it needs to be replenished one drum at a time. These drums are heavy, making the replenishment operation inefficient, requiring a lot of manual labor, and prone to oil leakage accidents, posing a great threat to safe operation and property.

[0005] Currently, there are no automatic refueling devices in China. Foreign products only offer refueling devices secured by level sensors and hoses, which cannot achieve fully automatic intelligent refueling. Most companies still use manual refueling, making automatic refueling essentially a blank market. Traditional refueling methods mostly rely on manual or mechanical operation. While simple to operate, inexpensive, and easy to maintain, they also have significant drawbacks: Because traditional refueling devices are mechanical, they cannot achieve high-precision metering; accuracy can only be controlled within a certain error range, making them unsuitable for applications with strict accuracy requirements. Mechanical refueling machines are slow, requiring manual operation and unable to automate the refueling process. Furthermore, as traditional refueling equipment, mechanical refueling machines have a relatively short lifespan, requiring long-term maintenance and incurring high maintenance costs.

[0026] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0027] like Figure 2 As shown, an oil injection system with an automatic oil replenishment device includes a transport and movement device and a lubrication system. The transport and movement device includes an omnidirectional moving platform 9 and an oil replenishment robot 6. Both the lubrication system and the oil replenishment robot 6 are mounted on the omnidirectional moving platform 9. The end of the oil replenishment robot 6 is equipped with an oil nozzle 13, which functions to fix the oil nozzle 13 and pull the trigger of the oil nozzle 13. The robot 6 connects the oil nozzle 13 to the oil nozzle. The lubrication system delivers lubricating medium to the oil nozzle 13 through a pump set 1 and a pipeline 11. Figure 4 and Figure 5 As shown, the oil filling system also includes an electronic control box 7, which is installed on the omnidirectional moving platform 9. The electronic control box 7 contains a control system, which is mainly used to start and stop the oil filling process.

[0028] like Figure 1 As shown, the refueling system with an automatic refueling device is essentially a refueling robot, equipped with a refueling manipulator 6. It can move via an omnidirectional moving platform 9 or be fixed in a specific area. When the control system receives a signal that the target fuel tank is empty, it acquires the coordinates of the fuel nozzle. The omnidirectional moving platform 9 moves to the coordinate position. The refueling manipulator 6 then locates the interface by activating the vision recognition device 12 at its end. The manipulator 6 then inserts the refueling nozzle 13 into the fuel nozzle. The laser docking device 14 confirms that the nozzle 13 is in place and sends a signal to the control system. The control system unlocks and starts the pump unit 1 to begin refueling. A flow switch 3 is installed on the pipeline 11, connected to the control system via a signal. The user can input the refueling amount or refueling time in advance. When the refueling amount or time reaches the set value, the control system stops the pump unit 1, the system returns to a self-locking state, the refueling manipulator 6 withdraws the refueling nozzle 13, and the robot automatically resets to the maintenance area. The control system and signal transmission method are existing technologies, as are the vision recognition device 12 and the laser docking device 14.

[0029] The flow signal collected by flow switch 3 can also be connected to the on-site DCS (Distributed Control System) via electrical control box 7 for remote monitoring. Flow switch 3 is a high-precision gear flow meter that is not affected by temperature changes in refueling accuracy and can adapt to oils of various viscosities.

[0030] The lubrication system includes a pump unit 1, an oil tank, a dual-cylinder filter 2, and a pipeline 11. The pump unit 1 draws lubricating medium from the oil tank through the pipeline 11, and after passing through the dual-cylinder filter 2 with a differential pressure switch, it is delivered to the lubrication nozzle 13 and finally injected into the lubrication point.

[0031] The visual recognition device 12 and laser docking device 14 at the end of the robotic arm are both connected to the control system.

[0032] A temperature gauge 5 and a pressure gauge 4 are installed on the pipeline 11, which can display the oil temperature and pressure values ​​in the system in real time.

[0033] The omnidirectional mobile platform 9 is equipped with four-wheel drive omnidirectional wheels 8, namely Mecanum wheels, which mainly enable the omnidirectional mobile platform 9 to move in any direction, and can respond quickly and reach the designated location quickly.

[0034] like Figure 3 As shown, the omnidirectional mobile platform 9 is also equipped with an emergency stop switch 10, which is used in case of an emergency on site.

[0035] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-creative modifications to this embodiment as needed after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
