Description

Technical Field

[0001] This utility model relates to the field of wind turbine gearbox technology, specifically a rapid repair device for broken teeth in wind turbine gearboxes. Background Technology

[0002] Wind power generation is an indispensable part of the modern energy system. One of its core components, the wind turbine gearbox, often suffers from tooth breakage due to harsh operating conditions, long-term heavy-load operation, and irregular load impacts. Tooth breakage can lead to the failure of the entire gearbox, causing the wind turbine to shut down. This not only results in direct power generation losses but may also cause damage to other components, increasing maintenance costs.

[0003] Currently, the common method for repairing broken gears is to replace the entire gearbox. However, this method is extremely costly, complex, and time-consuming, severely impacting the operating efficiency and economic benefits of wind power equipment. Some gearbox repair equipment also has several drawbacks. For example, it cannot clamp and repair different types of broken gears, nor can it flexibly adjust the clamped gears. Because the clamps cannot adapt to different shapes and sizes of broken gears, frequent clamp changes or adjustments are required when replacing different gear models, increasing maintenance time and costs. Furthermore, the inflexible clamping position and angle require maintenance personnel to spend more time and effort on manual adjustments, which may not achieve the desired clamping effect. This not only reduces repair efficiency but may also lead to unstable repair quality, affecting the overall performance of the wind turbine gearbox. Therefore, a rapid repair device for broken gears in wind turbine gearboxes is needed to address these issues. Utility Model Content

However, this method is extremely costly, complex, and time-consuming, severely impacting the operating efficiency and economic benefits of wind power equipment. Some gearboxes for repairing broken gears also have numerous drawbacks. For example, they cannot clamp and repair different types of broken gears, nor can they flexibly adjust the clamped gears. Because the clamps cannot adapt to different shapes and sizes of broken gears, frequent clamp changes or adjustments are necessary when replacing different gear models, increasing maintenance time and costs. Furthermore, the inflexible clamping position and angle require maintenance personnel to spend more time and effort on manual adjustments, which may not even achieve the desired clamping effect.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] For examples, please refer to Figures 1-4This utility model provides a technical solution:

[0026] A rapid repair device for broken teeth in a wind turbine gearbox includes a main body 1, a rotating component 2 fixedly connected to the top of the main body 1, and a clamping component 3 fixedly connected to the top of the rotating component 2.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the rotating assembly 2 includes a protective box 201, inside which a second motor 202 is installed. The output end of the second motor 202 is fixedly connected to a rotating rod 203. The clamping assembly 3 includes a base 301, with an L-shaped plate 302 fixedly connected to the top of the base 301. A telescopic rod 303 is installed inside the L-shaped plate 302, and the output end of the telescopic rod 303 is fixedly connected to a movable jaw 304. The telescopic rod 303 controls the movable jaw 304 to slide in the groove inside the chuck body 305, thereby allowing the movable jaw 304 to clamp broken teeth of different sizes. Since this clamping method can quickly adapt to broken teeth of various sizes, maintenance personnel no longer need to spend a lot of time on complex clamp replacement or adjustment work when facing broken tooth failures of different types of gears. This greatly shortens the preparation time before maintenance, improves maintenance efficiency, ensures that the fan can be restored to operation more quickly, and reduces economic losses caused by downtime.

[0028] The rotating rod 203 extends to the outside of the protective box 201 and is fixedly connected to the base 301. A chuck body 305 is fixedly connected to the top of the base 301. The chuck body 305 has a sliding groove inside, and the movable jaw 304 slides inside the groove. There are three L-shaped plates 302, telescopic rods 303, and movable jaws 304. Driven by the second motor 202, the rotating rod 203 drives the clamping mechanism on the top of the base 301 to rotate omnidirectionally. The omnidirectionally rotating clamping mechanism can be flexibly adjusted to find the optimal repair path. This greatly improves the flexibility and adaptability of maintenance work, reduces repair difficulties caused by space constraints, and optimizes the repair path according to actual work needs by using the omnidirectionally rotating clamping mechanism, reducing unnecessary operation steps and improving repair efficiency.

[0029] In this embodiment, as Figure 1 and Figure 4As shown, the main body 1 includes a support frame 101. A first motor 102 is mounted on the side of the support frame 101. A lead screw 103 is fixedly connected to the output end of the first motor 102. A threaded block 104 is threadedly connected to the side of the lead screw 103. A support plate 105 is fixedly connected to the top of the threaded block 104. The support plate 105 is fixedly connected to the protective box 201. A slide rail 106 is fixedly connected to the top of the support frame 101. The support plate 105 slides on the slide rail 106. Reinforcing ribs 108 are fixedly connected inside the support frame 101. Several reinforcing ribs 108 are provided. A bearing housing 107 is mounted on the side of the support frame 101, and a lead screw 103 extends into the bearing housing 107. Driven by the first motor 102, a threaded block 104 moves threadedly on the lead screw 103. Because the threaded block 104 is fixedly connected to the support plate 105, and in conjunction with the sliding of the support plate 105 on the slide rail 106, the rotating assembly 2 and clamping assembly 3 on the top of the support plate 105 can move as a whole. This threaded movement allows for a wide range of linear movement, enabling the rotating assembly 2 and clamping assembly 3 to operate within a large working space. This is particularly useful for complex gear structures that require repair in different locations, allowing maintenance personnel to easily adjust the component positions and find the optimal repair path.

[0030] The working process of this utility model is as follows: When the wind turbine gearbox broken tooth quick repair device designed using this solution is in operation, the maintenance personnel place the gear to be repaired on the chuck body 305. The telescopic rod 303 controls the sliding of the movable jaw 304 in the slide groove inside the chuck body 305 to clamp broken teeth of different sizes. The second motor 202 drives the rotating rod 203 to drive the clamping mechanism on the top of the base 301 to rotate in all directions. The clamping mechanism can be flexibly adjusted, and the maintenance personnel do not need to replace or readjust the clamps. The first motor 102 drives the lead screw 103 to rotate. The threaded block 104 on the lead screw 103 moves along the length direction of the lead screw 103 under the drive of the thread. Since the threaded block 104 is fixedly connected to the support plate 105, the support plate 105 slides on the slide rail 106, thereby driving the rotating component 2 and the clamping component 3 to move as a whole. This allows the rotating component 2 and the clamping component 3 to move precisely to the position of the broken tooth that needs to be repaired, providing convenience for subsequent repair operations.

[0031] Although embodiments of the present invention have been shown and described, 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.
