Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine yaw copper sleeve removal, specifically relating to a hydraulic removal device for wind turbine yaw copper sleeve. Background Technology

[0002] In the field of wind power generation, the stable operation of wind turbines is crucial for ensuring the reliability and stability of power supply. Among them, the yaw system, as a key component of the wind turbine, is responsible for adjusting the direction of the wind turbine to always align with the wind direction, thereby maximizing wind energy capture. The yaw bushing, as one of the core components of the yaw system, plays a key role in supporting and reducing friction. Its operating status directly affects the performance of the yaw system and the overall efficiency of the wind turbine. Traditional wind turbine yaw bushings are usually installed in an embedded manner, tightly assembled in the sleeve of the wind power platform. Although this installation method ensures the stability and reliability of the yaw bushing to a certain extent, it brings many inconveniences in the actual wind turbine maintenance process. When the yaw bushing wears, ages, or has other faults due to long-term operation and needs to be replaced or repaired, the embedded installation makes the removal process extremely difficult.

[0003] Currently, maintenance personnel often lack specialized and effective tools and equipment when removing yaw bushings, relying mainly on simple mechanical means such as knocking and prying. These methods are not only cumbersome and time-consuming, but also prone to damaging the yaw bushing and surrounding sleeve components. Damage to components during removal not only increases maintenance costs but may also affect the subsequent safe operation of the wind turbine. Furthermore, difficulties in the removal process can delay the progress of the entire maintenance work, thereby affecting the power generation efficiency and economic benefits of the wind turbine. Therefore, this utility model proposes a hydraulic removal device for wind turbine yaw bushings. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 3 This is the first embodiment of the present utility model, which provides the following technical solution: a hydraulic removal device for a wind turbine yaw copper sleeve, comprising...

[0024] An adjustable support platform erected on top of the wind power platform 7 includes a U-shaped support frame 1 erected on top of the wind power platform 7 and covering the sleeve 8 inside, and a support plate 2 inserted into the inside of the U-shaped support frame 1.

[0025] A hollow hydraulic jack 3 is placed on top of the support plate 2 and inside the U-shaped support frame 1. A lead screw 4 passes through the inside of the hollow piston rod 31 at the top of the hollow hydraulic jack 3, and the bottom end of the lead screw 4 passes through the inside of the yaw copper sleeve 9 and is threadedly connected to the yaw copper sleeve 9. A rod nut 5 is threadedly installed at the top of the lead screw 4 relative to the top of the hollow piston rod 31. After the operator first connects the bottom end of the lead screw 4 to the threaded hole 91 of the yaw copper sleeve 9, the hollow piston rod 31 can be driven to rise by pressing the handle of the hollow hydraulic jack 3. During the process of the hollow piston rod 31 rising, the lead screw 4 will be lifted by the rod nut 5, and the yaw copper sleeve 9 can be gradually lifted out from the inside of the sleeve 8. This greatly simplifies the process of removing the yaw copper sleeve 9, and the operator can quickly and easily complete the removal operation, which significantly improves the removal efficiency during maintenance.

[0026] In this embodiment, preferably, both sides of the U-shaped support frame 1 are provided with multiple strip-shaped slots 11 for inserting the support plate 2, so that in actual use, the operator can select to insert the support plate 2 into the appropriate strip-shaped slot 11 according to the actual use needs, adjust the height of the hollow hydraulic jack 3, and prevent the hollow hydraulic jack 3 from having insufficient stroke.

[0027] In this embodiment, preferably, two side blocks 22 are symmetrically welded and fixed on the top surface of the support plate 2 relative to the two sides of the U-shaped support frame 1, so that after the support plate 2 is inserted into the strip-shaped socket 11, it can be limited in the horizontal direction to prevent the support plate 2 from moving unnecessarily.

[0028] In this embodiment, preferably, the front surface of the support plate 2 is provided with a strip-shaped notch 21 corresponding to the lead screw 4, so that after the hollow hydraulic jack 3 and the lead screw 4 are combined, they can be directly pushed in from the front of the support plate 2 to complete the placement of the hollow hydraulic jack 3 on the top of the support plate 2.

[0029] In summary, in actual use, the U-shaped support frame 1 is first erected at a suitable position on top of the wind power platform 7. Then, the support plate 2 is inserted into the appropriate strip-shaped socket 11, allowing the support plate 2 to be connected with the U-shaped support frame 1, thus completing the rapid construction of the adjustable support platform. At this point, the lead screw 4 is passed through the hollow piston rod 31, achieving the combination of the lead screw 4 and the hollow hydraulic jack 3. Then, the hollow hydraulic jack 3 is placed on top of the support plate 2, allowing the bottom end of the lead screw 4 to pass through the strip-shaped notch 21 to the support plate. Insert the bottom of the insert plate 2, then insert the bottom end of the lead screw 4 all the way down to the inside of the yaw copper sleeve 9, and screw the bottom end of the lead screw 4 into the threaded central hole 91 and tighten it to complete the connection between the bottom end of the lead screw 4 and the yaw copper sleeve 9. At this time, screw the rod nut 5 down from the top of the lead screw 4 to the top of the hollow piston rod 31, and then press the operating handle of the hollow hydraulic jack 3 to make the hollow piston rod 31 rise and push the lead screw 4 up through the rod nut 5, so that the yaw copper sleeve 9 can be gradually lifted out of the sleeve 8, and the yaw copper sleeve 9 can be quickly removed.

[0030] Example 2

[0031] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that a quick-stop structure 6 is provided on the bottom of the support plate 2 relative to the side of the strip notch 21. The quick-stop structure 6 can block the front of the screw 4, preventing the hollow hydraulic jack 3 from sliding away from the front of the support plate 2 during use, and also preventing the screw 4 from sliding out from the front opening of the strip notch 21.

[0032] In this embodiment, preferably, the quick-closing structure 6 includes a support rod 61 welded and fixed to the bottom surface of the support plate 2 and located to the left of the strip-shaped notch 21; a limiting stop 62 movably sleeved on the surface of the support rod 61 (the limiting stop 62 can slide up and down on the surface of the support rod 61 and rotate around the support rod 61); a base plate 64 fixed to the bottom surface of the support rod 61; and a spring 63 sleeved on the surface of the support rod 61 and located between the limiting stop 62 and the base plate 64. The limiting stop 62 is located directly in front of the lead screw 4 and can block and limit the lead screw 4. The quick-closing structure 6 also includes a circular locking block 65 fixed to the bottom surface of the support plate 2 and located to the right of the strip-shaped notch 21; and a circular locking hole 66 opened on the surface of the limiting stop 62. The circular locking block 65 is inserted into the circular locking hole 66. The hole 66 allows the limiting stop 62 to be limited during daily use, preventing it from being easily pushed away. When it is necessary to release the obstruction of the screw rod 4 by the limiting stop 62, simply pull the limiting stop 62 down forcefully, causing it to slide down the surface of the support rod 61. This compresses the spring 63, causing the circular locking block 65 to move out of the circular locking hole 66. At this point, the limiting stop 62 can be rotated 90 degrees around the support rod 61, so that the limiting stop 62 is no longer blocking the screw rod 4 directly in front of it. This eliminates the obstruction and limitation on the screw rod 4. The hollow hydraulic jack 3 can then be moved forward from the top of the support plate 2, allowing the screw rod 4 to slide out from the front opening of the strip notch 21, thus achieving a quick separation between the hollow hydraulic jack 3 and the support plate 2.

[0033] In this embodiment, preferably, the bottom end of the spring 63 abuts against the top surface of the base plate 64, and the top end of the spring 63 abuts against the bottom surface of the limiting stop 62.

[0034] In this embodiment, preferably, a strip-shaped protrusion is fixed on both ends of the limiting stop 62, which facilitates the operator to pull down and rotate the limiting stop 62.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
