Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 3 , an intelligent lubrication device for a door machine, comprising a base 1, a control cabinet 2 is fixedly connected to the top of the base 1, a lubrication pump 3 is installed at the inner bottom of the control cabinet 2, a shunt pipe 4 is fixedly connected to the output end of the lubrication pump 3, both ends of the shunt pipe 4 are fixedly connected to solenoid valves 5, a delivery pipe 6 is fixedly connected to the top of the solenoid valve 5, the other end of the delivery pipe 6 extends to the outside of the control cabinet 2 and is fixedly connected to a lubrication gear 7, a quantitative component is fixedly connected to the inner bottom of the control cabinet 2 at the rear side of the lubrication pump 3, the quantitative component is used for quantitative lubrication grease, a connecting plate 9 is fixed to the top of the lubrication gear 7, and mounting holes are opened at the four corners of the connecting plate 9.

[0024] Specifically, the control cabinet 2 is fixed on the top of the base 1, which is convenient for moving it by pushing the base 1, thereby improving the convenience of using the device and reducing the physical strength of workers to move. The lubricating pump 3 fixed on the inner bottom wall of the control cabinet 2 can be used to extract the lubricating grease, and the shunt pipe 4 can be used to divert the grease, so that alternating lubrication can be performed to form a lubrication cycle, which is convenient for recording and viewing, and the outflow of the lubricating grease can be controlled by the solenoid valve 5. The connecting plate 9 can be fixed above the gear ring through the mounting holes at the four corners, so that the lubrication gear 7 is meshed with the gear ring and grease flows out when rotating, thereby lubricating the gear ring, thereby reducing the workload of workers and reducing the danger during lubrication.

[0025] Reference Figure 4The quantitative component includes a quantitative box 8, which is fixedly connected to the inner bottom wall of the control cabinet 2. A motor 10 is installed on the outside of the quantitative box 8. A screw 18 is fixedly connected to the output end of the motor 10. The external thread of the screw 18 is connected to a threaded block 11. The external of the threaded block 11 is fixedly connected to a plurality of connecting rods 12, and the other ends of the plurality of connecting rods 12 are fixedly connected to a moving plate 13.

[0026] Specifically, the motor 10 can drive the screw 18 to rotate, thereby causing the threaded block 11 to slide inside the metering box 8, and the threaded block 11 can push multiple connecting rods 12 to move, thereby causing the connecting rods 12 to push the movable plate 13 to move. Since the outer side of the movable plate 13 is in contact with the inner wall of the metering box 8, the capacity inside the metering box 8 can be changed during movement, and under the control of the controller 17, quantitative delivery of grease can be achieved, and the amount of lubrication required for the gear ring can be accurately controlled to avoid waste of grease, thereby increasing the service life of the gear ring. The fixed block at the other end of the screw 18 can prevent the threaded block 11 from detaching.

[0027] Reference Figure 2 A controller 17 is installed on the upper part of the control cabinet 2, and a fat storage tank 16 is fixedly connected to the left side of the inner bottom of the control cabinet 2. A fat delivery pipe 15 is fixedly connected to the bottom of the fat storage tank 16, and the other end of the fat delivery pipe 15 is fixedly connected to the top through hole of the quantitative box 8.

[0028] Specifically, the internal controller 17 can be protected by the control cabinet 2 so that it can maintain stable operation. The output of lubricating grease can be controlled by the controller 17 to ensure the amount of grease used when lubricating the gear ring. A certain amount of grease can be stored in the grease storage tank 16 for easy use, and the grease can be transported to the quantitative component through the grease pipe 15 to achieve quantitative delivery of grease.

[0030] Specifically, the movement of the threaded block 11 can be limited by the movable plate 13 to keep it sliding horizontally, and the lubricating grease in the grease storage tank 16 can be transported to the metering box 8 for quantitative addition through the grease delivery pipe 15, and then the grease in the metering box 8 is transported to the lubrication pump 3 through the connecting pipe 14, so that the grease can be transported to the lubrication gear 7 through the delivery pipe 6, and the gear ring is lubricated through the oil outlet hole on the surface, thereby realizing the maintenance operation of the gear ring and extending the service life. The cabinet door 19 is used to facilitate opening the cabinet for maintenance.

[0031] Working principle: When using this device, first add lubricating grease to the grease storage tank 16, then fix the connecting plate 9 on the top of the gantry gear ring with bolts to fix the lubricating gear 7 and make the lubricating gear 7 mesh with the gear ring. Then, the lubricating pump 3 allows the lubricating grease to be transported to the metering box 8 through the grease pipe 15, and then transported to the delivery pipe 6 through the connecting pipe 14, and then flows out through the oil outlet hole opened on the surface of the lubricating gear 7 to lubricate the surface of the gear ring, making maintenance and replacement convenient, while improving the work efficiency during gear ring lubrication, reducing the labor intensity of employees, and eliminating safety risks. Among them, through the control of the controller 17, the lubricating grease inside the grease storage tank 16 can enter the metering box 8, and at the same time, the operation of the motor 10 can drive the screw 18 to rotate, so that the threaded block 11 slides inside the metering box 8, and the connecting rod 12 pushes the movable plate 13 to move, thereby changing the capacity inside the metering box 8. Under the control of the controller 17, quantitative delivery of grease can be achieved, and the amount of lubrication required for the gear ring can be accurately controlled to avoid waste of grease, thereby increasing the service life of the gear ring.
