Description

Technical Field

[0001] This utility model belongs to the field of wind power equipment maintenance technology, specifically a pneumatic disassembly device for yaw brake. Background Technology

[0002] In the field of wind power generation, the yaw brake is a crucial component ensuring the stable operation of wind turbines. With the development of wind power technology, the installed capacity of wind turbines is continuously increasing, and the size and weight of the yaw brake are also increasing accordingly. When repairing, replacing, or maintaining the yaw brake, it needs to be removed from the yaw system of the wind turbine. Currently, the existing methods for removing yaw brakes typically involve manual disassembly using simple tools such as wrenches. While these methods are relatively simple, manual disassembly is difficult and inefficient. Furthermore, the weight of the yaw brake makes manual disassembly highly susceptible to accidents, hindering safer disassembly operations. Utility Model Content

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3As shown, this utility model provides a technical solution: a pneumatic disassembly device for a yaw brake, including a fixed base plate 1, a support column 2 fixedly installed on the upper surface of the fixed base plate 1, an installation cross plate 3 fixedly installed on the upper surface of the support column 2, a yaw brake 4 disposed on the upper surface of the installation cross plate 3, a support diagonal rod 5 connected to the lower surface of the installation cross plate 3 fixedly installed on the left side of the support column 2, a fixing block 6 fixedly installed on the right side of the installation cross plate 3, a slidable lifting column 7 disposed inside the fixing block 6, a pressing cover plate 8 fixedly installed on the upper surface of the lifting column 7, a connecting cross plate 9 fixedly installed on the inner side of the lifting column 7, a movable plate 10 fixedly installed on the lower surface of the lifting column 7, a rotating screw 11 threaded through the interior of the movable plate 10, a stabilizing plate 12 fixedly installed on the upper surface of the rotating screw 11, and a connecting cross plate 9 fixedly installed on the lower surface of the stabilizing plate 12. An L-shaped connecting column 13 is connected to the right side of plate 3. A fixed horizontal plate 14 is fixedly installed on the inner side of the fixed base plate 1. A stabilizing bracket 15 is fixedly installed on the right side of the fixed horizontal plate 14. A first bevel gear 16 is fixedly installed at the bottom end of the rotating screw 11. A fixed bracket 17 is fixedly installed on the right side of the fixed horizontal plate 14. A rotatable rotating shaft 18 is provided on the right side of the fixed bracket 17. A rotating gear 19 is fixedly installed on the outer surface of the rotating shaft 18. A second bevel gear 20 is fixedly installed at the front end of the outer surface of the rotating shaft 18. The first bevel gear 16 meshes with the second bevel gear 20. An air pump 21 is fixedly installed on the upper surface of the fixed base plate 1. The output end of the air pump 21 is connected to a transmission pipe 22. A cylinder 23 connected to the upper surface of the fixed base plate 1 is connected to the right side of the transmission pipe 22. A rack vertical plate 24 is fixedly installed on the output end of the cylinder 23. The rotating gear 19 meshes with the rack vertical plate 24.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, the fixed block 6 has a sliding circular hole inside, which is slidably connected to the lifting column 7. The sliding circular hole inside the fixed block 6 and the lifting column 7 cooperate with each other to improve the stability of sliding. There are two sets of support diagonal rods 5, and the length of the two sets of support diagonal rods 5 is 450 mm. The two sets of support diagonal rods 5 cooperate with each other to improve the stability of support. The upper surface of the mounting plate 3 is provided with a rubber pad, and the upper surface of the rubber pad is provided with anti-slip texture. The anti-slip texture of the rubber pad on the upper surface of the mounting plate 3 effectively increases the friction during installation.

[0021] Specifically, such as Figure 3As shown, the inside of the stabilizing bracket 15 is provided with a circular through hole. The inner wall of the circular through hole is rotatably connected to the bottom of the rotating screw 11. The circular through hole inside the stabilizing bracket 15 and the rotating screw 11 cooperate with each other to facilitate more stable driving. The inside of the moving plate 10 is provided with a threaded hole. The size of the threaded hole is adapted to the size of the rotating screw 11. The threaded hole inside the moving plate 10 and the rotating screw 11 cooperate with each other to facilitate more stable rotation.

[0022] The working principle of this utility model is as follows:

[0023] When it is necessary to disassemble the yaw brake 4, start the air pump 21. The air pump 21 drives the cylinder 23 to move. The cylinder 23 drives the rack vertical plate 24 to move. The rack vertical plate 24 meshes with the rotating gear 19 to drive the rotating shaft 18 to rotate. The rotating shaft 18 drives the second bevel gear 20 to rotate. The second bevel gear 20 meshes with the first bevel gear 16 to drive the rotating screw 11 to rotate. The rotating screw 11 drives the moving plate 10 to move. The moving plate 10 drives the lifting column 7 to move. The lifting column 7 drives the pressing cover plate 8 to move upward to release the fixation of the yaw brake 4. Then the yaw brake 4 can be disassembled.

[0024] In summary, this pneumatic disassembly device for the yaw brake, by setting up an air pump 21 and a cylinder 23 to drive the rack vertical plate 24 to mesh with the rotating gear 19, drives the second bevel gear 20 to mesh with the first bevel gear 16, drives the rotating screw 11 to rotate, and drives the lifting column 7 and the pressing cover plate 8 to move up and down to fix and disassemble the yaw brake 4. This makes the disassembly of the yaw brake 4 simpler and more convenient, and can be completed without manual intervention. This makes the disassembly of the yaw brake 4 more efficient, effectively avoids safety accidents during manual disassembly, facilitates safer disassembly operations, and improves the convenience for users.
