Description

Technical Field

[0001] This utility model relates to the field of wind power equipment maintenance technology, and in particular to a tool for replacing the yaw brake of a wind turbine. Background Technology

[0002] The wind power industry is one of my country's strategic industries, and the domestic demand for wind power equipment is increasing. Among them, the yaw brake is an important component of the wind turbine braking system. Its braking performance directly determines whether the wind turbine can operate normally. The yaw brake is fixed to the yaw brake disc by multiple bolts and brakes the yaw by friction pads. As the installed capacity increases, the yaw brake also becomes larger. The yaw brake of wind turbines above 1.5MW usually weighs more than 200 kg. Therefore, when the yaw brake needs to be replaced, the operation is very inconvenient.

[0003] In the prior art, such as the Chinese patent CN209380646U entitled "A Tool for Replacing Yaw Brakes of Wind Turbine Units," a main rod is included. A base frame is fixedly connected to the bottom end of the main rod, and a support mechanism is fixedly connected to the upper end of the main rod near the base frame. A traction mechanism is provided on the upper end of the main rod near the support mechanism, and a cable reeling mechanism is provided at the top of the traction mechanism. A bolt is threaded through the rear end of the inner side of the base frame. This utility model uses bolts to fix the base frame to the external yaw brake disc. The cable reeling mechanism drives the inner rod on the traction mechanism to slide, and a pin on the traction mechanism drives the yaw brake away from the yaw brake disc. The support mechanism holds the yaw brake away from the yaw brake disc and positions it appropriately for external crane lifting, thus facilitating yaw brake replacement by maintenance workers and saving time and effort.

[0004] Although this type of wind turbine yaw brake replacement tool uses a support mechanism to place the yaw brake away from the yaw brake disc and position it appropriately for external crane lifting, thus facilitating yaw brake replacement for maintenance workers and saving time and effort, it still has several shortcomings in practical application. First, the position of its base frame fixing bolts is difficult to adjust flexibly according to the hole spacing of different yaw brake discs. When encountering brake discs with inconsistent hole spacing, the tool has poor installation adaptability, or even cannot be installed, limiting the tool's range of use. Second, the fixed position of the pin shaft in the traction mechanism used to connect the yaw brake cannot adapt to the differences in the positions of the reserved holes on both sides of different specifications of yaw brakes. This means that when replacing different models of brakes, the pin shaft may not be able to accurately pass through the hole, making it difficult to achieve reliable clamping, thus affecting the smooth progress of the replacement operation, and therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the existing technology where the position of the base frame fixing bolts is difficult to adjust flexibly according to the hole spacing of different yaw brake discs and cannot adapt to the differences in the position of the reserved holes on both sides of different specifications of yaw brakes. Therefore, a yaw brake replacement tool for wind turbine units is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a wind turbine yaw brake replacement tool, comprising a pole, a base frame fixedly mounted at the bottom end of the pole, a mounting plate one fixedly mounted on the side of the base frame, a movable plate one provided on the side of the mounting plate one, a bolt threaded inside the movable plate one, a placement frame fixedly mounted on the side of the pole, a sliding sleeve sleeved on the surface of the pole, a crossbar fixedly mounted on the side of the sliding sleeve, a telescopic rod slidably connected inside the crossbar, a second mounting plate two fixedly mounted at one end of the telescopic rod, a second movable plate two provided on the side of the second mounting plate two, a pin penetrating through the inner side of the second movable plate two, and a rotating shaft fixedly mounted on the surface of the sliding sleeve.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a tool for replacing the yaw brake of a wind turbine, including a pole 1, a base frame 2 fixedly installed at the bottom end of the pole 1, an mounting plate 3 fixedly installed on the side of the base frame 2, a movable plate 4 provided on the side of the mounting plate 3, bolts 5 threadedly connected to the inside of the movable plate 4, a placement frame 6 fixedly installed on the side of the pole 1, a sliding sleeve 7 sleeved on the surface of the pole 1, a crossbar 8 fixedly installed on the side of the sliding sleeve 7, and a telescopic rod 9 slidably connected inside the crossbar 8. One end of the telescopic pole 9 is fixedly mounted with a mounting plate 2 10. A movable plate 2 11 is provided on the side of the mounting plate 2 10. A pin 12 is passed through the inner side of the movable plate 2 11. A rotating shaft 13 is fixedly mounted on the surface of the sliding sleeve 7. A take-up reel 14 is movably connected to the surface of the rotating shaft 13. Steel strand 141 is wound on the surface of the take-up reel 14. A screw 15 is threadedly connected to the side of the sliding sleeve 7. A lug 16 is fixedly mounted on one end of the screw 15. A screw hole 18 is opened on the side of the upright pole 1. The surface of the take-up reel 14 is fixed... A sliding block 21 is fixedly connected to the side of the movable plate 4, and a double-acting screw 22 is rotatably connected inside the mounting plate 3. A sliding rod 23 is fixedly installed inside the mounting plate 3, and a rotating head 24 is fixedly installed at one end of the double-acting screw 22. A sliding block 25 is fixedly installed to the side of the movable plate 11, and a double-acting screw 26 is rotatably connected inside the mounting plate 10. A sliding rod 27 is fixedly installed inside the mounting plate 10, and one end of the double-acting screw 26 is fixedly connected to the sliding plate 11. The rotating head 28 is installed. One end of the steel strand 141 is fixedly connected to the side of the mounting plate 2 10. The screw 15 is threadedly connected to the screw hole 18. The double-acting screw 22 is threadedly connected to the sliding block 21. The sliding block 21 is slidably connected to the sliding rod 23. The double-acting screw 26 is threadedly connected to the sliding block 25. The sliding block 25 is slidably connected to the sliding rod 27. The inside of the lug 16 is fitted with a force-adding rod 17. The inside of the lug 2 19 is fitted with a force-adding rod 20.

[0020] In this embodiment, when the yaw brake of the wind turbine needs to be replaced, the base frame 2 is first fixed in a suitable position. The rotating head 24 is then rotated. Since the double-acting screw 22 is threadedly connected to the sliding block 21, and the sliding block 21 is slidably connected to the sliding rod 23, the rotation of the double-acting screw 22 causes the sliding block 21 and the moving plate 4 to move horizontally along the sliding rod 23. The position of the moving plate 4 can be adjusted according to the position of the pre-drilled hole in the yaw brake. Similarly, rotating the rotating head 28, through the double-acting screw 26, the sliding block 25, and... With the cooperation of slide bar 27, the position of moving plate 21 can be adjusted so that pin 12 can accurately pass through the reserved holes on both sides of the yaw brake to achieve the connection and fixation of the brake. Then, rotate the force rod 20 to drive the take-up reel 14 to rotate around the shaft 13. Since one end of the steel strand 141 is fixedly connected to the side of the mounting plate 210, the take-up reel 14 winds up the steel strand 141 when it rotates, pulling the mounting plate 210, moving plate 211 and yaw brake to move, removing the brake from the installation position and moving it above the placement frame 6.

[0021] Example 2: Figures 1-4 As shown, the surface of the placement rack 6 is provided with a limiting plate 29, and a protrusion 30 is fixedly connected to the lower surface of the limiting plate 29. A groove 31 is opened on the surface of the placement rack 6. A two-way lead screw 32 is rotatably connected inside the placement rack 6. A rotating head 33 is fixedly installed at one end of the two-way lead screw 32. The protrusion 30 and the groove 31 are slidably connected, and the two-way lead screw 32 and the protrusion 30 are threadedly connected.

[0022] In this embodiment, after the yaw brake is placed on the placement frame 6, the rotating head 33 is rotated, and the double-acting screw 32 rotates accordingly. Since the double-acting screw 32 is threadedly connected to the protrusion 30 and the protrusion 30 is slidably connected to the groove 31, the rotation of the double-acting screw 32 drives the protrusion 30 to slide in the groove 31, thereby driving the limiting plate 29 to move. The position of the limiting plate 29 can be adjusted according to the size of the yaw brake to limit and fix the brake, prevent it from sliding and shifting on the placement frame 6, ensure the stability and safety of the brake placement, and facilitate subsequent operations or waiting for external hoisting equipment to transfer it.

[0023] The working principle of this embodiment is as follows: When using this wind turbine yaw brake replacement tool, first place the base frame 2 at the bottom of the upright 1 in a suitable position near the yaw brake inside the wind turbine nacelle. According to the drain hole at the bottom of the yaw brake disc, rotate the rotating head 24 to drive the double-acting screw 22 to rotate. Since the double-acting screw 22 is threadedly connected to the sliding block 21, and the sliding block 21 is slidably connected to the sliding rod 23, the moving plate 4 moves horizontally along the sliding rod 23, thereby moving the moving plate 4... Adjust bolt 5 to the position corresponding to the drain hole at the bottom of the yaw brake disc, and then use bolt 5 to fix the base frame 2 to the yaw brake disc. Next, slide the sliding sleeve 7 along the surface of the upright 1, adjust the sliding sleeve 7 to a suitable height, and then rotate the screw 15 to make it threadedly connected to the screw hole 18 on the side of the upright 1 to fix the position of the sliding sleeve 7. Then, according to the position of the reserved holes on both sides of the yaw brake to be replaced, rotate the rotating head 28 in the mounting plate 2 10, and through the double-acting screw 2 26 and the sliding block 2 25 and the sliding rod 2 27, the two-way screw 2 26 is connected to the sliding block 2 25 and the sliding rod 2 27. The movable plate 11 moves the pin 12 horizontally, accurately passing the pin 12 through the pre-drilled holes on both sides of the yaw brake, thus connecting the tool and the brake. Then, the extension rod 20 is inserted into the lug 29, and rotating the extension rod 20 causes the take-up reel 14 to rotate around the shaft 13. Since one end of the steel strand 141 is fixedly connected to the side of the mounting plate 10, the take-up reel 14 rotates to wind up the steel strand 141, pulling the mounting plate 10, movable plate 11, and yaw brake upwards, thus moving the brake from the mounting plate 10. The mounting position is removed, and then the rotating head 33 inside the placement frame 6 is rotated. The double-acting screw 32 rotates accordingly. Since the double-acting screw 32 is threadedly connected to the protrusion 30 and the protrusion 30 is slidably connected to the groove 31, the double-acting screw 32 drives the protrusion 30 to slide in the groove 31, which drives the limiting plate 29 to move. The position of the limiting plate 29 is adjusted according to the size of the brake to limit and fix the brake placed on the placement frame 6, preventing it from sliding or tipping over during handling or hoisting, and significantly improving the safety of operation.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
