[0043] As shown in Figure 2 and Figure 3 In order to facilitate lubricating oil supply, the feeding assembly comprises an oil pipe 13, a fixing ring 12 and an extension rod 9 fixed to the lower surface of the connecting frame 6.

[0044] The lower side of the fixing ring 12 is in sliding cooperation with the supporting ring 34. The lower end of the extension rod 9 is connected with the fixing ring 12. The extension rod 9 is used for pressing the fixing ring 12 on the supporting ring 34, so that the fixing ring 12 performs synchronous lifting movement with the top plate 10.

[0045] The fixed ring 12 has a second oil storage chamber connected to the oil pipe 13. The first oil storage chamber has several first connecting holes 22 on its side wall. The second oil storage chamber has several second connecting holes 20 on its side wall. When rotated, the first connecting holes 22 and the second connecting holes 20 are intermittently connected.

[0046] like Figure 5 As shown, in order to automatically center and clamp during lifting and lowering, and automatically release during lowering for easy placement and retrieval, the lifting clamping support assembly includes a slider 33, a support 27, several clamping plates 30, several connecting rods 32, a cylinder 2, a lifting rod 24 connected to the telescopic end of the cylinder 2, and four wedge-shaped slippers 25 fixedly connected to the worktable 1.

[0047] The inclined surface of the wedge-shaped sliding claw 25 is provided with an inclined groove 28 for the slider 33 to slide at an angle. The support 27 is provided with a horizontal groove 31 for the clamping plate 30 to slide. The clamping plate 30 and the corresponding slider 33 are connected by the connecting rod 32. The clamping plate 30 is also connected to the center of the support 27 by a second spring 29.

[0048] The top of the lifting rod 24 moves through the wedge-shaped sliding claw 25 and connects to the support 27. A guide rod 26 for guidance is provided at the lower part of the support 27.

[0049] The cylinder 2 is used to drive the support 27 to move up and down through the lifting rod 24, thereby driving the slider 33 to slide along the inclined slide groove 28, and driving the clamping plate 30 to slide along the horizontal slide groove 31 through the second spring 29.

[0050] Example 2

[0051] This embodiment provides a valve string assembly lubrication device. The main difference from embodiment 1 is that, in order to reduce the friction of the contact surface and facilitate lifting by utilizing the shape change of the contact surface, a plurality of ball bearings 21 are respectively provided on the contact surface of the arc-shaped boss 11 and the arc-shaped pressure plate 8.

[0052] Example 3

[0053] This embodiment provides a valve string assembly lubrication device. The main difference from Embodiment 1 is that, in order to achieve a movable sealing fit, sealing gaskets 17 are respectively provided at the upper and lower ends of the side of the fixed ring 12 that contacts the top plate 10.

[0054] Specifically, the valve string assembly lubrication device provided by this utility model has the following specific working steps:

[0055] First, place the valve seat on top of the support 27. Start the cylinder 2 to drive the support 27, which will then move the valve seat upwards toward the connecting frame 6. The lifting and clamping support assembly 3 will then fix the valve seat in place. After moving to the appropriate position, the connecting pipe 18 and the brush bristles 14 will be inside the valve seat. The motor 5 will start and drive the rotating shaft 7 to rotate via a belt.

[0056] When the rotating shaft 7 rotates, it carries the circular plate 16, the first spring 15, the top plate 10, the connecting pipe 18, and the brush bristles 14 along with it. When the top plate 10 rotates, its surface comes into contact with and is squeezed by the arc-shaped pressure plate 8. Under the squeezing action, the top plate 10 carries the connecting pipe 18 and the brush bristles 14 up and down along the circular plate 16. At the same time, the feeding assembly feeds grease into the top plate 10. The grease enters the connecting pipe 18 through the top plate 10 and is sprayed out from the holes on the surface of the connecting pipe 18.

[0057] The grease is flung onto the inner wall of the valve seat by centrifugal force, while the rotating bristles 14 continuously coat the grease adhering to the inner wall of the valve seat. Because the bristles 14 and connecting pipe 18 slide along the circular plate 16 with the top plate 10, the angle at which the bristles 14 coat the inner wall of the valve seat constantly changes, resulting in a more even coating of the grease onto the inner wall of the valve seat. After lubrication, the valve seat can be detached using a cylinder and removed to the assembly point.

[0058] When grease is supplied to the top plate 10, an external oil pump connected to the oil pipe 13 delivers the grease to the interior of the retaining ring 12. The grease enters the top plate 10 through the first connecting hole 20 and the second connecting hole 22 between the retaining ring 12 and the top plate 10. Simultaneously, as the top plate 10 reciprocates up and down, the retaining ring 12 moves along with it, causing the length of the telescopic rod 9 to continuously change. The telescopic rod 9 provides additional fixing force to the retaining ring 12, keeping it in a stable state.

[0059] Before placing the valve seat, the second spring 29 is in a stretched state. After the valve seat is placed on the support surface, the cylinder 2 can be activated to transport it. When the support 27 moves, the clamping plate 30 and the slider 33 will slide along the wedge-shaped sliding claw 25. Because the surface of the wedge-shaped sliding claw 25 is inclined, the slider 33 and the clamping plate 30 slide along the support 27. The second spring 29 will contract and move the clamping plate 30 closer to the valve seat. When the support 27 reaches the specified height, the clamping plate 30 will fix the valve seat, realizing the device's rapid fixing and positioning of the valve seat. When the support 27 moves, the guide rod 26 will slide along the worktable, and the guide rod 26 will provide additional guidance for the worktable.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
