Description

Technical Field

[0001] This utility model relates to a device for disassembling disc springs of brake calipers in wind turbine generators, belonging to the field of wind turbine brake technology. Background Technology

[0002] Wind turbine brakes are key components of wind turbines, used to decelerate, stop, or keep moving parts stationary. Disc springs, as key elements of the brakes, provide braking torque and store and release energy through their elastic deformation to ensure braking effectiveness.

[0003] During long-term operation, disc springs in wind turbines can suffer fatigue, deformation, and cracks due to repeated loads, leading to insufficient braking force and slow braking response, which affects the safe and stable operation of the wind turbine. To promptly identify and address these issues, regular maintenance, disassembly, inspection, and replacement of the disc springs are necessary. However, during the maintenance of traditional high-speed wind turbine brakes, the high pressure on the disc springs poses a safety hazard during disassembly, and the springs are difficult to remove, causing significant inconvenience to maintenance work.

[0004] Therefore, there is an urgent need to improve the wind turbine brake caliper disc spring disassembly device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wind turbine brake caliper disc spring disassembly device. By setting up a support base and a clamping arm, with the clamping arm set at one end of the support base, the device can accurately control the release of the disc spring pressure plate during disassembly of the brake disc spring, avoiding problems such as instantaneous pressure release or uneven release that may occur in traditional disassembly methods, and ensuring that the disc spring is in a safe and stable state during the disassembly process.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0011] Preferably, a slide rail is fixedly installed at the bottom of the fixed plate, a limit frame is slidably installed on the slide rail, and a limit frame is fixedly installed at one end of the limit frame.

[0012] Preferably, the limiting frame has a groove, and two second springs are symmetrically installed inside the groove. A locking rod is fixedly installed at one end of the second spring, and a locking block is fixedly installed at one end of the slide rail.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of 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] like Figures 1-5 As shown in this embodiment, a wind turbine brake caliper disc spring disassembly device is provided.

[0026] A wind turbine brake caliper disc spring disassembly device includes a support base 1 and multiple clamping arms 2. An adjustment mechanism 3 is provided on the support base 1. The adjustment mechanism 3 includes multiple sliding grooves 4 formed on the clamping arms 2. Multiple sliders 5 that are slidably connected to the sliding grooves 4 are fixedly installed on one end of the support base 1 near the clamping arms 2. Screws 6 are movably installed on both sides of the support base 1. A movable block 7 that is threadedly connected to the screws 6 is fixedly installed on one side of the clamping arms 2.

[0027] Furthermore, a turntable 8 is fixedly installed on one end of the screw 6. Multiple push rods 9 are evenly fixedly installed on the surface of the turntable 8, and the surface of the push rods 9 is provided with anti-slip texture. Multiple fixing plates 10 are fixedly installed on the surface of the support base 1. Multiple first springs 11 are fixedly installed on one end of the fixing plate 10. Each first spring 11 is fixedly connected to a support rod 12 at its lower end. Each support rod 12 is movably connected to the fixing plate 10. A magnetic block 13 is fixedly installed on one end of the support rod 12. A magnetic ring 14 is fixedly installed on the turntable 8. The support rod 12 consists of a horizontal plate and a vertical rod. The first spring 11 is fixedly set on the horizontal plate. A handle is fixedly set on the side of the horizontal plate away from the vertical rod. A slide rail 15 is fixedly installed at the bottom of the fixing plate 10. A limit frame 16 is slidably installed on the slide rail 15. A limit frame 17 is fixedly installed on one end of the limit frame 16.

[0028] By utilizing the support base 1 and clamping arms 2, with clamping arms 2 positioned at one end of the support base 1, the brake is placed in the opening between the two clamping arms 2 during brake disc spring disassembly. A small jack of appropriate size and hydraulic pressure is placed directly below the brake to precisely control the release of the disc spring pressure plate during disassembly. This avoids problems such as instantaneous or uneven pressure release that may occur in traditional disassembly methods, and prevents accidents such as disc spring ejection and injury caused by high disc spring pressure during manual disassembly. This reduces operational risks and ensures the personal safety of workers. Compared to traditional manual disassembly methods, this tooling can quickly and efficiently complete the disassembly of the disc spring, saving time and labor costs, reducing wind turbine downtime for maintenance, and improving overall operation and maintenance efficiency. It eliminates the need for manual handling of heavy objects or the use of laborious tools to counteract disc spring pressure, greatly reducing the labor intensity of workers and making disassembly easier. Furthermore, the support base 1 and clamping arms 2 are connected by an adjusting mechanism 3, allowing adjustment of the distance between the two clamping arms 2 on the support base 1, facilitating the handling of different models of brake discs. The spring allows for disassembly and reassembly, making it more versatile. Rotating the screw 6, which in turn moves the moving block 7, pushes the clamping arms 2, thus adjusting the distance between the two clamping arms 2. The turntable 8, mounted on one end of the screw 6, facilitates rotation and provides friction to prevent slippage during operation. After adjusting the distance between the two clamping arms 2, the magnetic block 13 and magnetic ring 14 fix the turntable 8, indirectly limiting the screw 6 and preventing it from retracting. If the clamping arm 2 is accidentally touched and rotates, causing the clamping arm 2 to loosen its grip on the brake, the magnetic block 13 and the magnetic ring 14 need to be separated when adjusting the clamping arm 2. Since the magnetic block 13 is supported by multiple first springs 11, it has a certain reset performance. At this time, after pulling the support rod 12 to separate the magnetic block 13 and the magnetic ring 14, the limit frame 16 is pushed to insert the limit frame 17 into the support rod 12. This can effectively prevent the magnetic block 13 from resetting during the adjustment process and prevent it from affecting the adjustment operation. The support rod 12 is more convenient to pull by the handle.

[0029] Furthermore, the limit frame 16 has a groove 18, and two second springs 19 are symmetrically installed inside the groove 18. A locking rod 20 is fixedly installed on one end of the second spring 19, and a locking block 21 is fixedly installed on one end of the slide rail 15. The diameter of the locking rod 20 matches the inner diameter of the slot on the locking block 21, and one end of the locking rod 20 is set to be arc-shaped. Multiple threaded through holes 22 are evenly opened on the clamping arm 2. The slide groove 4 and the slider 5 are both set to be T-shaped.

[0030] After the limiting frame 17 is inserted into the support rod 12, the locking block 21 on one end of the slide rail 15 is inserted into the groove 18 on the limiting frame 16. At the same time, the locking rod 20 in the groove 18 is connected to the slot on the locking block 21 under the support of the second spring 19 to form a locking, thereby fixing the limiting frame 16 and the limiting frame 17 and further preventing loosening. At the same time, the diameter of the locking rod 20 is set to match the inner diameter of the slot on the locking block 21, which can improve the stability of the locking. Multiple threaded through holes 22 are opened on the clamping arm 2. According to the size of the brake, iron strips can be installed on the threaded through holes 22 at the corresponding positions to increase the disassembly resistance. At the same time, setting the slide groove 4 and the slider 5 to a T-shape can further prevent the clamping arm 2 from falling off the support base 1.

[0031] In this embodiment, as Figures 1-5 As shown in the figure, the working process of the wind turbine brake caliper disc spring disassembly device provided in this embodiment is as follows:

[0032] Place the brake in the opening between the two clamping arms 2, rotate the screw 6 to drive the moving block 7 to move by its own thread, so that the moving block 7 pushes the clamping arms 2 to adjust the distance between the two clamping arms 2 and clamp the brake. Place a small jack of appropriate size and hydraulic pressure directly below the brake to help disassemble the brake disc spring.

[0033] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
