[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0035] See Figure 1-4;
[0036] This utility model provides a torque verification device for the yaw system of a wind turbine generator, comprising:
[0037] Testing bracket 1 serves as the support carrier for the torque verification device.
[0038] An adjustment component is mounted on the detection bracket 1;
[0039] The testing mechanism is mounted on an adjustment component, which controls its up-and-down movement.
[0040] The testing institutions include:
[0041] The detection support plate 31 is slidably mounted on the adjustment assembly;
[0042] The instrument bracket 32 is vertically and slidably mounted on the detection support plate 31. A torque detector 33 is installed in the instrument bracket 32, and a detection rod 34 is installed at the output end of the torque detector 33.
[0043] The detection head 35 is located at the bottom of the detection rod 34 and its rotation is controlled by the torque detector 33.
[0044] The transmission connecting block 36 is fixedly connected to the detector bracket 32;
[0045] A cylinder 37 is mounted on the detection support plate 31. A transmission guide rod 38 is mounted on the output end of the cylinder 37. The transmission guide rod 38 is slidably inserted into the transmission connecting block 36. A transmission circular plate 39 is mounted on the bottom end of the transmission guide rod 38. The transmission circular plate 39 is located below the transmission connecting block 36 and is used to lift the transmission connecting block 36. A spring 3a is mounted on the transmission guide rod 38 and is used to push the transmission connecting block 36 downward.
[0046] By adopting the above technical solution, when using the torque verification device for the yaw system of this wind turbine generator set, the testing bracket 1 is first used as a stable support carrier for the entire device and placed in a suitable position. The adjusting components allow for flexible control of the up-and-down sliding of the testing mechanism, thus adapting to the installation height and position of different specifications of wind turbine generator set yaw systems, facilitating accurate alignment of the testing mechanism with the receiving testing components. The testing support plate 31, as the basic load-bearing component, is adjusted in position under the drive of the adjusting components. After the testing support plate 31 moves to a suitable position, the testing instrument bracket 32 can slide vertically on the testing support plate 31, further... The height of the torque detector 33 is finely adjusted to ensure that the detection head 35 at the bottom of the detection rod 34 can accurately contact the connection and transmission components to be tested in the yaw system. After contact is established, the torque detector 33 controls the rotation of the detection head 35 to apply a detection torque to the yaw system components and acquire torque parameter data in real time. During the testing process, the cylinder 37 plays an important role. Its output transmission guide rod 38 is slidably inserted into the transmission connecting block 36. When the cylinder 37 works, the transmission guide rod 38 drives the transmission circular plate 39 to lift the transmission connecting block 36 upward, causing the detector bracket 32 and the torque detector 33 to generate an upward force. The tension is used to simulate some of the stress conditions experienced by the yaw system during actual operation; while the spring 3a, mounted on the transmission guide rod 38, pushes the transmission connecting block 36 downward when the cylinder 37 is not working, ensuring stable contact between the detection head 35 and the detection component, thus ensuring the continuity and stability of the detection process; through this workflow, the torque parameters of the yaw system components can be detected comprehensively and accurately; by adjusting the coordinated work of the components and the detection mechanism, this device can quickly complete the position adjustment of the detection mechanism and the precise docking of the detection head, greatly reducing manual operation steps and time consumption, and significantly improving detection efficiency; Traditional testing methods rely heavily on manual operation, which can easily introduce human error and affect the accuracy of the test results. In contrast, this device, through the combination of mechanical structure and instrumentation, has a high degree of automation, reduces human interference, and can more accurately obtain the torque parameters of yaw system components, thus improving the reliability of the test results. By accurately detecting the torque parameters of yaw system components, it is possible to promptly detect situations where the component torque does not meet design requirements, avoiding malfunctions such as inaccurate yaw, jamming, and abnormal noises caused by abnormal torque parameters. This ensures the safe and stable operation of wind turbine generators, extends equipment lifespan, and reduces maintenance costs.
[0047] As a preferred embodiment of the above technical solution, the detection head 35 is provided in at least one specification, and the detection head 35 is threadedly fitted onto the detection rod 34;
[0048] In this embodiment, based on the connection and transmission structure characteristics of different components in the yaw system of the wind turbine generator set, and the specific requirements for torque verification, a suitable specification of the detection head 35 is selected from at least one specification. The detection head 35 is provided in at least one specification and is installed on the detection rod 34 using a threaded fitting method. This allows the torque verification device to adapt to the torque verification requirements of yaw systems of different models and specifications of wind turbine generator sets. Regardless of the bolt connections of different sizes or the transmission components of different shapes, accurate torque verification can be achieved by replacing the detection head 35 with a suitable specification, greatly improving the versatility and applicability of the device. The threaded fitting method makes the installation and removal of the detection head 35 very convenient. Operators do not need to use complex tools or perform cumbersome operations; a simple rotation is sufficient to replace the detection head 35. This not only saves time and improves work efficiency but also reduces operational difficulty, making torque verification work more convenient.
[0049] As a preferred embodiment of the above technical solution, a noise-reducing pad is provided at the top of the transmission circular plate 39, and the noise-reducing pad is disposed between the transmission circular plate 39 and the transmission connecting block 36.
[0050] In this embodiment, a noise-reducing rubber pad is provided between the transmission circular plate 39 and the transmission connecting block 36. This effectively absorbs and buffers the vibration and impact energy generated during their contact and relative movement. The noise-reducing rubber pad converts mechanical energy into heat energy and other forms of energy through its own elastic deformation, thereby significantly reducing the generation and propagation of noise, improving the working environment, and reducing hearing damage to operators. The presence of the noise-reducing rubber pad can avoid direct rigid contact between the transmission circular plate 39 and the transmission connecting block 36. In long-term testing operations, rigid contact can easily lead to wear on the surface of the components, reducing their service life. As a buffering medium, the noise-reducing rubber pad can reduce friction and wear between the two, extend the service life of the transmission circular plate 39 and the transmission connecting block 36, and reduce equipment maintenance costs.
[0051] As a preferred embodiment of the above technical solution, as shown in Figure 2, a guide plate 3b is vertically arranged on the detection support plate 31, and a guide block 3c is arranged on the detector bracket 32. The guide block 3c is slidably mounted on the guide plate 3b.
[0052] In this embodiment, the cooperation between the guide plate 3b and the guide block 3c ensures that the detector bracket 32 can only slide precisely in the vertical direction on the detection support plate 31, avoiding horizontal deviation or swaying of the detector bracket 32 during movement; ensuring that the detection head 35 can accurately contact the yaw system components, improving the accuracy of torque verification, and reducing detection errors caused by motion deviation.
[0053] As a preferred embodiment of the above technical solution, as shown in Figure 2, a stabilizing frame 3d is provided on the guide plate 3b, a stabilizing sleeve 3e is provided in the stabilizing frame 3d, and the detection rod 34 is slidably inserted into the stabilizing sleeve 3e.
[0054] In this embodiment, the stabilizing sleeve 3e provides precise guidance for the detection rod 34, restricting its horizontal freedom and limiting its movement to the vertical direction. This ensures that the detection head 35 accurately contacts the yaw system components, reducing detection errors caused by the swaying or offset of the detection rod 34 and improving the accuracy of torque verification. During the detection process, the detection rod 34 is subjected to various forces. The stabilizing sleeve 3e ensures that the detection rod 34 maintains a stable motion under these forces, enhancing the stability of the entire detection mechanism and preventing detection failures or equipment damage due to instability of the detection rod 34. It also reduces collisions and friction between the detection rod 34 and surrounding components, decreasing the wear and tear on the detection rod 34, extending its service life, and reducing equipment maintenance costs.
[0055] As a preferred embodiment of the above technical solution, as shown in Figure 4, the adjustment component includes:
[0056] Adjust the slide block 21, which is fixedly installed on the detection bracket 1;
[0057] The threaded rod 22 is vertically rotatably mounted in the adjusting slide 21 and is driven to rotate by a motor.
[0058] The adjusting slider 23 is slidably set in the adjusting slide block 21, and the adjusting slider 23 is threadedly fitted onto the threaded rod 22.
[0059] The connecting frame 24 is fixedly connected to the adjusting slider 23, and the connecting frame 24 is also fixedly connected to the detection support plate 31.
[0060] In this embodiment, when the height of the detection mechanism needs to be adjusted, the motor starts, driving the threaded rod 22 to rotate in the adjusting slide 21. Since the adjusting slider 23 is threaded onto the threaded rod 22 and is restricted by the sliding of the adjusting slide 21, it cannot rotate with the threaded rod 22. According to the principle of threaded transmission, the rotation of the threaded rod 22 is converted into linear motion of the adjusting slider 23. When the threaded rod 22 rotates in the forward direction, the adjusting slider 23 moves upward along the threaded rod 22; when the threaded rod 22 rotates in the reverse direction, the adjusting slider 23 moves downward along the threaded rod 22. The movement of the adjusting slider 23 will cause the connecting frame 24 to move together, and the connecting frame 24 is fixedly connected to the detection support plate 31. Therefore, the detection support plate... The detection head 31 slides up and down as the adjusting slider 23 moves; the sliding of the detection support plate 31 drives the entire detection mechanism to move up and down, thereby adjusting the height of the detection head 35 so that it can accurately contact the yaw system components at different heights; through the threaded transmission between the threaded rod 22 and the adjusting slider 23, the height of the detection mechanism can be precisely adjusted; the detection head 35 can be accurately moved to the required height according to the actual position of different components of the yaw system, ensuring the accuracy and reliability of the detection; the use of a motor to drive the threaded rod 22 to rotate realizes the automation of the height adjustment of the detection mechanism; compared with the traditional manual operation method, it greatly improves work efficiency and reduces the errors and labor intensity caused by manual operation.
[0061] As a preferred embodiment of the above technical solution, as shown in Figure 1, a dustproof plate 25 is provided on the adjusting slide 21, and a sliding groove is provided at the connection end between the connecting frame 24 and the detection support plate 31. The dustproof plate 25 is placed in the sliding groove to prevent dust from entering the adjusting slide 21.
[0062] In this embodiment, the working environment of the wind turbine generator set is usually quite harsh, with a large amount of dust, sand and other impurities. The threaded rod 22 and the adjusting slider 23 inside the adjusting slide 21 require precise matching and movement. If dust enters, it will cause problems such as thread wear and jamming, affecting the normal operation of the adjusting component. The dustproof plate 25 can effectively prevent dust and other impurities from entering the adjusting slide 21, protecting the threaded rod 22 and the adjusting slider 23 and extending their service life. Since the dustproof plate 25 reduces the corrosion of the adjusting component by dust and other impurities, it reduces the probability of the adjusting component malfunctioning, reduces the number of times the equipment needs to be repaired and replaced, and thus reduces maintenance costs.
[0063] As a preferred embodiment of the above technical solution, a limiting protective pad is provided at the bottom of the detector bracket 32, and the stabilizer 3d provides a lower limit for the detector bracket 32;
[0064] In this embodiment, if there were no limiting protective pad during the downward movement of the detector bracket 32, its bottom end might directly collide with the stabilizer 3d, potentially damaging the detector bracket 32 or the stabilizer 3d and affecting the normal use of the device. The limiting protective pad effectively buffers the impact force, avoids hard collisions, protects the detector bracket 32 and the stabilizer 3d, and extends the service life of the device. Through the cooperation of the limiting protective pad and the stabilizer 3d, the probability of failure due to collision during operation is reduced, improving the reliability and stability of the torque verification device, enabling it to operate stably for a long time in complex working environments.
[0065] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
