[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-5 As shown, the utility model provides a technical solution: an automatic lubrication device for a yaw gear ring, comprising a support plate 1, a yaw gear ring 2 is mounted on the support plate 1, a housing 3 is clamped to the inner wall of the yaw gear ring 2, the housing 3 is fixedly connected to the support plate 1, three gears 16 are mounted on the support plate 1, the gears 16 are meshed with the yaw gear ring 2, and an oil outlet hole 25 is opened on the gear 16;

[0021] The gear 16 is fixedly connected to an oil storage cylinder 17, and the top of the oil storage cylinder 17 is threadedly clamped with a second cover plate 18. Due to the presence of the second cover plate 18, the second cover plate 18 is clamped with the oil storage cylinder 17 through the outer thread, making the sealing of the oil storage cylinder 17 more stable;

[0022] The bottom end of the gear 16 is fixedly connected to a reducer 19, and the bottom end of the reducer 19 is installed with a motor 20. Because of the reducer 19, when the engine rotates, the reducer 19 reduces the speed and drives the gear 16 to rotate, preventing the gear 16 from rotating too fast and causing incomplete lubrication;

[0023] A baffle 4 is fixedly connected to the shell 3, and a first slide groove 5 is provided in the baffle 4, and a block 6 is clamped in the first slide groove 5. A clamping groove 7 is provided on the shell 3, and one end of the block 6 is clamped with the slot 7, and the other end of the block 6 is fixedly connected to a column 8, and a limit block 14 is installed on the column 8. A second slide groove 9 is provided on the baffle 4, and the inner wall of the second slide groove 9 is clamped with the outer side of the column 8. A bearing 10 is installed on the baffle 4, and a first cover plate 11 is fixedly connected to one side of the bearing 10. Due to the bearing 10, the first cover plate 11 is limited while ensuring the rotation of the first cover plate 11, so that the rotation of the first cover plate 11 is more stable;

[0024] The bearing 10 is outer-mounted with a torsion spring 12, the first cover plate 11 is provided with a third slide groove 13, the inner wall of the third slide groove 13 is mutually engaged with the outer side of the column 8, the first cover plate 11 is fixedly connected with a rotating handle 15, a protective cover 21 is installed on the support plate 1, and a plurality of oil guide holes 22 are provided on the support plate 1. Due to the provision of the protective cover 21, excess lubricating oil is blocked on the support plate 1 by the protective cover 21 during lubrication, preventing the lubricating oil from scattering and causing waste, and facilitating the collection of the lubricating oil;

[0025] An oil outlet pipe 23 is installed on the bottom side of the oil guide hole 22, and an oil collecting cylinder 24 is fixedly connected to the bottom end of the oil outlet pipe 23. Due to the provision of the oil collecting cylinder 24, excess lubricating oil passes through the oil guide hole 22 and enters the oil collecting cylinder 24 via the oil outlet pipe 23, which facilitates the collection and reuse of the lubricating oil and prevents the lubricating oil from accumulating on the support plate 1 and affecting the normal operation of the lubrication device.

[0026] The working principle of the present invention is as follows: when the yaw gear ring 2 is installed, the operator rotates the handle 15 to drive the first cover plate 11 to rotate. The first cover plate 11 causes the column 8 to slide in the third slide groove 13 and the second slide groove 9, and at the same time causes the torsion spring 12 to deform and generate force. The column 8 pulls the block 6 to move inward in the first slide groove 5. The operator then sleeves the yaw gear ring 2 on the outside of the housing 3. At this time, the operator releases the handle 15, and the torsion spring 12 returns to its original position to drive the first cover plate 11 and the column 8 to move. 8 pushes the clamping block 6 to move outward in the first slide groove 5, and the clamping block 6 passes through the clamping groove 7 and is in close contact with the yaw ring gear 2. During lubrication, the operator rotates the turning handle 15 again to separate the clamping block 6 from the yaw ring gear 2. The operator starts the motor 20 to drive the gear 16 to rotate, and the gear 16 drives the yaw ring gear 2 to rotate. When the oil outlet contacts the yaw ring gear 2, the lubricating oil flows onto the yaw ring gear 2, and the excess lubricating oil flows through the oil guide hole 22 and the oil outlet pipe 23 into the oil collecting cylinder 24.
