[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] like Figure 1-4As shown, the utility model provides a technical solution: a yaw gear ring lubrication device, comprising a yaw gear ring body 1, an oiling device 2 is provided on one side of the yaw gear ring body 1, the oiling device 2 comprises a liquid storage tank 21, a connecting device 3 is provided between the liquid storage tank 21 and the yaw gear ring body 1, a feeding pipe 22 is fixedly connected to one side of the liquid storage tank 21, a cylinder 25 is fixedly connected to one side of the liquid storage tank 21, the inner wall of the cylinder 25 is connected to the inner wall of the liquid storage tank 21, a plurality of discharge holes 26 are provided on one side of the cylinder 25, a motor 27 is fixedly connected to one side of the cylinder 25, the output end of the motor 27 is fixedly connected to a circular shaft 28, the other end of the circular shaft 28 is rotatably connected to the inner wall of the cylinder 25, a plurality of sealing plates 29 are fixedly connected to the surface of the circular shaft 28, the surface of the sealing plate 29 is in contact with the inner wall of the cylinder 25, and by providing the oiling device 2, the oiling device 2 is first fixed on the cylinder 25 through the connecting device 3. At the meshing position of the yaw gear ring body 1 and the reducer gear, lubricating oil is injected into the liquid storage tank 21 through the feed pipe 22, so that the lubricating oil enters the cylinder 25 and intercepts the sealing plate 29. At this time, the motor 27 is started, so that the motor 27 drives the circular shaft 28 to rotate, so that the circular shaft 28 drives multiple sealing plates 29 to rotate in contact with the inner wall of the cylinder 25, so that the multiple sealing plates 29 evenly push the lubricating oil inside the liquid storage tank 21 through the multiple discharge holes 26 through rotation, so that the lubricating oil is sprayed out through the multiple discharge holes 26 and sprayed onto the meshing position between the yaw gear ring body 1 and the reducer gear, so that the lubricating oil can be evenly sprayed onto the meshing area of ​​the yaw gear ring body 1 and the reducer gear for lubrication, reducing the situation where the uneven amount of lubricating oil added affects the lubrication effect, and improving the convenience and efficiency of lubricating the meshing position of the yaw gear ring body 1 and the reducer gear.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the surface of the feed pipe 22 is threadedly connected to a sealing cover 23, and the surface of the sealing cover 23 is provided with a plurality of anti-slip protrusions. By providing the sealing cover 23, the sealing cover 23 can be closed to the inlet position of the feed pipe 22, thereby reducing the situation where the lubricating oil splashes out of the liquid storage tank 21 through the feed pipe 22. A viewing hole 24 is provided on one side of the liquid storage tank 21, and a transparent plate is fixedly connected to the inner wall of the viewing hole 24. By providing the viewing hole 24, personnel can view the storage situation of the lubricating oil in the liquid storage tank 21 through the viewing hole 24, thereby improving the convenience for personnel to observe the lubricating oil reserve in the liquid storage tank 21. A guide plate 210 is fixedly connected to the inner wall of the liquid storage tank 21, and the cross-section of the guide plate 210 is trapezoidal. By providing the guide plate 210, the guide plate 210 can guide the lubricating oil in the liquid storage tank 21 into the cylinder 25 under the action of its own slope, thereby reducing the situation where some lubricating oil accumulates in the liquid storage tank 21 when the lubricating oil reserve is small.

[0028] Specifically, such as Figure 4As shown, the connecting device 3 includes a rectangular frame 31, which is fixedly connected to the yaw gear ring body 1. A circular hole 32 is opened on one side of the rectangular frame 31. A screw hole block 33 is fixedly connected to one side of the liquid storage tank 21. The inner wall of the screw hole block 33 is threadedly connected with a bolt 34. The surface of the screw hole block 33 is slidably connected to the inner wall of the rectangular frame 31. The surface size and shape of the bolt 34 are adapted to the size and shape of the inner wall of the circular hole 32. By setting the connecting device 3, the liquid storage tank 21 is first manually moved so that the liquid storage tank 21 drives the screw hole block 33 to slide. The hole block 33 moves, and when the screw hole block 33 moves to a position completely inserted into the interior of the rectangular frame 31, the inner wall of the circular hole 32 coincides with the inner wall of the screw hole block 33. At this time, the bolt 34 is rotated by a tool so that the bolt 34 is rotated into the circular hole 32 and the interior position of the screw hole block 33 to fix the position of the screw hole block 33 and the liquid storage tank 21, thereby completing the rapid assembly of the oil filling device 2 and the yaw gear ring body 1. At the same time, the oil filling device 2 can be conveniently disassembled at a later time, thereby improving the flexibility of use of the oil filling device 2 and the convenience of later maintenance.

[0029] Specifically, such as Figure 4 As shown, a limiting groove 35 is provided on one side of the screw hole block 33, and the inner wall of the rectangular frame 31 is fixedly connected to the limiting block 36. The surface size and shape of the limiting block 36 are adapted to the size and shape of the inner wall of the limiting groove 35. By setting the limiting block 36 and the limiting groove 35, the limiting block 36 can be located inside the limiting groove 35 to assist in limiting the screw hole block 33 inserted into the rectangular frame 31, thereby reducing the shaking of the screw hole block 33 and further improving the connection stability between the rectangular frame 31 and the screw hole block 33. One side of the rectangular frame 31 is fixedly connected to a reinforcement block 37, and the reinforcement block 37 is fixedly connected to the yaw gear ring body 1. By setting the reinforcement block 37, the reinforcement block 37 can strengthen the connection between the rectangular frame 31 and the yaw gear ring body 1, thereby reducing the separation of the rectangular frame 31 from the yaw gear ring body 1 during use.

[0030] The working principle of this utility model is:

[0031] S1. First, manually move the liquid storage tank 21 so that the liquid storage tank 21 drives the screw hole block 33 to move. When the screw hole block 33 moves to a position where it is fully inserted into the interior of the rectangular frame 31, the inner wall of the circular hole 32 coincides with the inner wall of the screw hole block 33. At this time, the bolt 34 is rotated by a tool so that the bolt 34 is rotated into the circular hole 32 and the interior position of the screw hole block 33 to fix the position of the screw hole block 33 and the liquid storage tank 21, thereby completing the rapid assembly of the oil adding device 2 and the yaw gear ring body 1, so that the oil adding device 2 is located in the meshing area between the yaw gear ring body 1 and the reducer gear.

[0032] S2. At this time, lubricating oil is injected into the liquid storage tank 21 through the feed pipe 22, so that the lubricating oil enters the interior of the cylinder 25 and intercepts the sealing plate 29. At this time, the motor 27 is started, so that the motor 27 drives the circular shaft 28 to rotate, so that the circular shaft 28 drives the multiple sealing plates 29 to rotate in contact with the inner wall of the cylinder 25, so that the multiple sealing plates 29 can evenly push the lubricating oil inside the liquid storage tank 21 through the multiple discharge holes 26 through rotation, so that the lubricating oil is sprayed out through the multiple discharge holes 26 and sprayed onto the meshing position between the yaw gear ring body 1 and the reducer gear for lubrication.
