Technical Field

[0001] This utility model relates to the field of disassembly and assembly tools, specifically a disassembly and assembly tool for a wind turbine yaw brake. Background Technology

[0002] The yaw brake of the wind turbine provides braking force to keep the unit in the windward position. When the unit yaws, the brake provides damping torque to maintain yaw balance.

[0003] A search revealed that Chinese patent public number CN 219747810 U relates to the field of wind turbine yaw brake technology, and particularly to a tool for disassembling and assembling a wind turbine yaw brake. This tool is an axially driven hydraulic wrench-assisted disassembly and assembly tool that can be easily engaged with a nut sleeve. The tool includes a hydraulic wrench with a hexagonal hole. A positioning sleeve is mounted on the side of the hydraulic wrench, and a U-shaped frame is detachably mounted on the positioning sleeve. Positioning screws are vertically mounted on the two vertical ends of the U-shaped frame. A ring frame is fitted onto the two sets of positioning screws. Two gears are symmetrically and movably mounted on the ring frame. A motor for driving the gears is mounted on the ring frame. A hexagonal shaft is inserted into the hexagonal hole. One end of the hexagonal shaft has a hexagonal drive hole, and the other end of the hexagonal shaft has multiple ring teeth arranged in a linear array along its axis. The gears mesh with the ring teeth to drive the hexagonal shaft axially.

[0004] The brake disassembly and assembly tools in the aforementioned patent still have certain shortcomings. When replacing the brake pads of the yaw brake of domestic wind turbines, tools such as hydraulic wrenches, adjustable wrenches, oil drums, wind turbine keys, cabinet keys, and multimeters are required for disassembly and assembly. However, in actual disassembly and assembly of existing wind turbine yaw brakes, due to the weight of the yaw brake body and the large number of bolts and fastening components on both sides of the brake, it is difficult to rotate and position the brake repeatedly, which greatly reduces the efficiency of brake disassembly and assembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tool for disassembling and assembling yaw brakes for wind turbines. This tool solves the problem that existing yaw brakes for wind turbines are difficult to disassemble and assemble due to their weight and the presence of numerous bolts and fasteners on both sides, requiring repeated flipping and repositioning, which significantly reduces the efficiency of disassembly and assembly.

[0006] This utility model provides the following technical solution: a wind turbine yaw brake disassembly and assembly tool, including a support base, a yaw brake body is provided on the top of the support base, and a disassembly and assembly tool assembly is provided on the support base;

[0007] The disassembly and assembly tool assembly includes a right support plate vertically disposed on the top side of the support base. A servo motor is mounted on the right support plate, and a first abutment clamp is disposed on the side of the right support plate. A rotating connecting block is fixedly connected to the drive shaft of the servo motor, and the end of the rotating connecting block is fixedly connected to the side of the first abutment clamp. A left support plate is vertically disposed on the other side of the top of the support base. A limit slot is formed at the top of the left support plate, and an abutment connecting seat is slidably inserted into the limit slot. Four limit rods are vertically disposed on the inner wall of the limit slot. The ends of the insertion rods all penetrate around the perimeter of the abutment connector. A rotating connecting shaft is rotatably provided on the side of the abutment connector. The end of the rotating connecting shaft is connected to a second abutment clamp. One side of the yaw brake body is fixed by the abutment of the second abutment clamp, and the other side of the yaw brake body is abutted by the first abutment clamp. A drive cylinder is installed on the left support plate. The drive end of the drive cylinder extends into the limiting slot. The drive end of the drive cylinder is connected to a cylinder transmission rod. The end of the cylinder transmission rod is fixedly connected to the side of the abutment connector.

[0008] Preferred technical solution 1: A retraction groove is provided on the side of the left support plate, and a bottom support plate is slidably inserted into the retraction groove.

[0009] Preferred technical solution 2: The bottom support plate is rotatably connected to a drive screw, and the end of the drive screw is threaded through the inner wall of the retraction groove and extends to the outer side of the left support plate.

[0010] Preferred technical solution 3: Two limiting grooves are symmetrically opened on both sides of the inner wall of the limiting slot, and two limiting blocks are symmetrically arranged on both sides of the abutting connecting seat, and the limiting blocks are slidably inserted into the limiting grooves.

[0011] This design allows the contact connector to slide more smoothly in the limiting slot.

[0012] Preferred technical solution four: Both the first and second contact plates are L-shaped bends.

[0014] Preferred technical solution five: The bottom support plate is located at the bottom end of the side of the yaw brake body, and the bottom support plate abuts against the bottom side of the yaw brake body.

[0015] This design enables the bottom support plate to again abut and limit the bottom end of the yaw brake body after it has been abutted by the first and second abutting plates, ensuring that the yaw brake body is stably positioned between the left and right support plates.

[0016] Compared with the prior art, this utility model provides a tool for disassembling and assembling a yaw brake of a wind turbine, which has the following advantages:

[0017] (1) This utility model provides a disassembly and assembly tool assembly on the side of the yaw brake body on the support base. The first and second abutting clamps in the disassembly and assembly tool assembly can abut and fix the two sides of the yaw brake body under the drive of the servo motor and the drive cylinder, so that the yaw brake body is raised on the top of the support base, making it more convenient for users to disassemble and assemble. When the servo motor is started, it can drive the yaw brake body to rotate or adjust the angle through the first abutting clamp, making it more convenient for users to disassemble and assemble the fasteners on the yaw brake body. It is no longer necessary to manually rotate the yaw brake body repeatedly, making the overall operation more convenient and greatly improving the disassembly and assembly efficiency of the yaw brake body, making it more convenient for users to use.

[0024] Please see Figure 1-4 ,

[0025] Example 1: A tool for disassembling and assembling a yaw brake of a wind turbine includes a support base 1, a yaw brake body 2 is provided on the top of the support base 1, and a disassembly and assembly tool assembly 3 is provided on the support base 1.

[0026] The disassembly and assembly tool assembly 3 includes a right support plate 301 vertically disposed on the top side of the support base 1. A servo motor 302 is mounted on the right support plate 301. A first abutment clamp 303 is disposed on the side of the right support plate 301. A rotating connecting block 304 is fixedly connected to the drive shaft of the servo motor 302. The end of the rotating connecting block 304 is fixedly connected to the side of the first abutment clamp 303. A left support plate 305 is vertically disposed on the other side of the top of the support base 1. A limit slot 306 is opened at the top of the left support plate 305. An abutment connecting seat 307 is slidably inserted into the limit slot 306. Four limit rods 308 are vertically disposed on the inner wall of the limit slot 306. The ends of the limit rods 308 all penetrate through the perimeter of the abutment connecting seat 307. A rotating connecting shaft 309 is rotatably disposed on the side of the abutment connecting seat 307. The end of the rotating connecting shaft 309 is connected to a second abutment clamp 310.

[0027] One side of the yaw brake body 2 is fixed by the second abutting clamp 310, and the other side of the yaw brake body 2 is abutted by the first abutting clamp 303. A drive cylinder 311 is installed on the left support plate 305. The drive end of the drive cylinder 311 extends into the limiting slot 306. The drive end of the drive cylinder 311 is connected to the cylinder transmission rod 312. The end of the cylinder transmission rod 312 is fixedly connected to the side of the abutting connecting seat 307. A retraction groove 313 is opened on the side of the left support plate 305. A bottom support plate 314 is slidably inserted in the retraction groove 313. A drive screw 315 is rotatably connected to the side of the bottom support plate 314. The end of the drive screw 315 is threaded through the inner wall of the retraction groove 313 and extends to the outer side of the left support plate 305.

[0028] Example 2: The difference between this example and Example 1 is that two limiting grooves are symmetrically opened on both sides of the inner wall of the limiting slot 306, and two limiting blocks are symmetrically arranged on both sides of the abutting connecting seat 307, with the limiting blocks slidably inserted into the limiting grooves.

[0029] This makes the contact connector 307 slide more smoothly in the limiting slot 306.

[0030] Example 3: The difference between this example and Example 1 is that the first contact plate 303 and the second contact plate 310 are both L-shaped bends.

[0031] This allows the first contact plate 303 and the second contact plate 310 to better support and fix the two sides of the yaw brake body 2.

[0032] Example 4: The difference between this example and Example 1 is that the bottom support plate 314 is located at the bottom end of the side of the yaw brake body 2, and the bottom support plate 314 abuts against the bottom side of the yaw brake body 2.

[0033] This allows the bottom support plate 314 to again contact and limit the bottom end of the yaw brake body 2 after it has been contacted by the first contact plate 303 and the second contact plate 310, ensuring that the yaw brake body 2 is stably positioned between the left support plate 305 and the right support plate 301.

[0034] In this embodiment, the existing wind turbine yaw brake is difficult to disassemble and assemble due to its heavy weight and numerous bolts and fasteners on both sides. This necessitates repeatedly flipping and repositioning the brake, which is quite challenging and significantly reduces the efficiency of the disassembly and assembly.

[0035] In summary, during implementation, when the user needs to remove the fastening bolts or other fastening components on the yaw brake body 2 and replace internal damaged parts, the user can first place the yaw brake body 2 between the right support plate 301 and the left support plate 305, so that one end of the yaw brake body 2 is supported and resisted by the first abutting clamp 303, while the other end of the yaw brake body 2 is supported and resisted by the second abutting clamp 310. The user can start the drive cylinder 311, and push the abutting connecting seat 307 toward one side of the yaw brake body 2 through the cylinder transmission rod 312, so that the abutting connecting seat 307 pushes the second abutting clamp 310 through the rotating connecting shaft 309, and both sides of the yaw brake body 2 can be fastened to the upper part of the support base 1.

[0036] Next, by rotating the drive screw 315, the user pushes the bottom support plate 314 inserted in the retraction groove 313 to the bottom of the yaw brake body 2, ensuring more stable force support for the yaw brake body 2. This makes it easier for the user to install and remove the fasteners on the yaw brake body 2. When the user needs to install or remove the fasteners on the bottom side of the yaw brake body 2, the user can pull the bottom support plate 314 back into the retraction groove 313. By starting the servo motor 302, the connecting shaft 309 is rotatably connected to the contact connecting seat 307, thereby rotating the stable contacting yaw brake body 2. Driven by the servo motor 302, the yaw brake body 2 can be quickly and easily flipped for installation and removal without the need for repeated manual flipping. The overall operation is more convenient, greatly improving the efficiency of installing and removing the yaw brake body 2 and making it more convenient for the user.
