Description

Technical Field

[0001] This utility model relates to the technical field of wind power equipment maintenance tools, and in particular to a portable tool for measuring and adjusting the yaw motor brake gap. Background Technology

[0002] Wind power equipment maintenance tools are important auxiliary equipment to ensure the stable operation of wind turbine generator sets. Their performance directly affects the efficiency and quality of equipment maintenance. In a wind power generation system, the yaw motor is responsible for driving the nacelle to rotate with the wind direction to maximize wind energy capture. The yaw motor brake, as an important braking component, plays a key role in the safe and stable operation of the unit due to its clearance accuracy.

[0003] In the existing technology, the traditional method of measuring and adjusting the brake clearance of yaw motors has some problems. In the measurement process, it usually relies on manual measurement using feeler gauges at single points. Due to the lack of a precise positioning structure, the measurement results are greatly affected by the operator's skills and experience, making it difficult to guarantee the accuracy and consistency of the data. In addition, the brake structures of different models of yaw motors vary greatly, requiring frequent replacement of feeler gauges of different thicknesses. However, existing tools have not been optimized for quick disassembly and assembly of feeler gauges, resulting in low adjustment efficiency, thus requiring improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where the measurement of the yaw motor brake gap relies on manual single-point operation, has low measurement accuracy and is greatly affected by operating experience, and has cumbersome feeler gauge replacement and low adjustment efficiency when the brake structure of different motor models is very different. Therefore, a portable tooling for measuring and adjusting the yaw motor brake gap is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a portable tool for measuring and adjusting the yaw motor brake gap, comprising a frame plate, a connecting block, and a feeler gauge. The frame plate and the connecting block are fixedly connected by bolts and nuts. A sleeve is fixedly installed inside the frame plate. A plug is movably connected to the outer surface of the feeler gauge. A magnet A is fixedly installed on the lower surface of the plug. A magnet B is fixedly installed on the inner side of the sleeve. A tension spring is fixedly connected to the inner side of the plug. A limit block is slidably connected inside the plug. A limit hole is opened on the side of the sleeve. A through hole is opened on the side of the frame plate.

[0006] Preferably, the frame plate, connecting block and feeler gauge are all set in three groups, and the feeler gauge is provided in the middle of each frame plate. The frame plates are distributed in a triangular shape and are movably connected by the connecting block.

[0007] Preferably, the insert block and the sleeve are slidably connected, and magnet A and magnet B are attracted to each other.

[0008] Preferably, one end of the tension spring is fixedly connected to one end of the limiting block.

[0009] Preferably, the limiting hole and the through hole are aligned with each other, and the limiting block and the limiting hole are slidably connected.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting the frame plate, connecting block and feeler gauge into three groups and distributing them in a triangular shape, the three groups of frame plates are movably connected by the connecting block, which can form a stable triangular measurement and adjustment structure around the yaw motor brake. When the brake gap is measured and adjusted, the triangular structure can simultaneously position and measure the brake from three directions. Compared with the traditional single-point measurement method, it can determine the brake gap more accurately and facilitate the operator to operate from different angles. Even when the space around the yaw motor is small, the position can still be flexibly adjusted, solving the problem of inconvenient operation caused by space limitation.

[0012] 2. In this utility model, by setting an insert block on the outer surface of the feeler gauge and slidingly connecting it with the insert sleeve inside the frame plate, combined with the adsorption between magnet A and magnet B, and the linkage structure of tension spring, limiting block and limiting hole, the feeler gauge assembly is stably installed and conveniently replaced. When it is necessary to replace feeler gauges of different thicknesses, the operator only needs to press the limiting block to disengage it from the limiting hole to complete the disassembly or replacement of the insert block. This realizes the convenience of feeler gauge installation, fixing and replacement, and improves the efficiency of the overall measurement and adjustment work. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a portable tool for measuring and adjusting the yaw motor brake clearance, including a frame plate 1, a connecting block 2, and a feeler gauge 3. The frame plate 1 and the connecting block 2 are fixedly connected by bolts 4 and nuts 5. A sleeve 6 is fixedly installed inside the frame plate 1. A plug 7 is movably connected to the outer surface of the feeler gauge 3. A magnet A8 is fixedly installed on the lower surface of the plug 7. A magnet B9 is fixedly installed on the inner side of the sleeve 6. A tension spring 10 is fixedly connected to the inner side of the plug 7. A limit block 11 is slidably connected inside the plug 7. The side of the insert 6 has a limiting hole 12, and the side of the frame plate 1 has a through hole 13. The frame plate 1, the connecting block 2, and the feeler gauge 3 are all set in three groups. The feeler gauge 3 is provided in the middle of the frame plate 1. The frame plates 1 are distributed in a triangular shape and are movably connected by the connecting block 2. The insert 7 is slidably connected to the insert 6. The magnet A8 and the magnet B9 are attracted to each other. One end of the tension spring 10 is fixedly connected to one end of the limiting block 11. The limiting hole 12 and the through hole 13 are aligned with each other. The limiting block 11 and the limiting hole 12 are slidably connected.

[0022] In this embodiment, when using the portable fixture for measuring and adjusting the yaw motor brake gap, the three sets of frame plates 1 are first fixedly connected by connecting blocks 2 using bolts 4 and nuts 5, so that the frame plates 1 are distributed in a triangular shape and are movably connected to form a stable measurement and adjustment structure. The fixture is placed at the yaw motor brake, with the frame plates 1 arranged around the brake. During the measurement operation, the feeler gauge 3 is slidably connected to the insert 6 inside the frame plate 1 through the insert block 7. Since the magnet A8 on the lower surface of the insert block 7 and the magnet B9 on the inner side of the insert 6 attract each other, the feeler gauge 3 can be quickly and firmly installed on the frame plate 1, preventing the feeler gauge 3 from loosening during the measurement process. At the same time, one end of the tension spring 10 inside the insert block 7 is fixedly connected to the limiting block 11. When the feeler gauge 3 is inserted into the insert 6, the limiting block 11 slides along the inside of the insert block 7 under the action of the tension spring 10. The feeler gauge 3 is inserted into the limiting hole 12 on the side of the insert sleeve 6 and the through hole 13 on the side of the frame plate 1, which further enhances the stability of the feeler gauge 3 installation and ensures that the feeler gauge 3 is accurately positioned during measurement. When the brake clearance needs to be adjusted, the triangularly distributed frame plate 1 can position and assist in the adjustment of the brake from three directions, which makes it convenient for operators to operate on multiple positions at the same time. Compared with the traditional method, it can more accurately control the synchronous and consistent adjustment of the three yaw brake pads. After the adjustment is completed, if it is necessary to replace the feeler gauge 3 or disassemble the tooling, press the limiting block 11 to make it disengage from the limiting hole 12, overcome the tension of the tension spring 10, and the feeler gauge 3 can be easily taken out from the insert sleeve 6. Then, by removing the bolt 4 and nut 5, the frame plate 1 and the connecting block 2 are separated to complete the disassembly of the tooling. The whole process is convenient and greatly improves the efficiency and accuracy of the measurement and adjustment of the yaw motor brake clearance.

[0023] The working principle of this embodiment is as follows: First, the three sets of frame plates 1 and connecting blocks 2 are fixedly connected using bolts 4 and nuts 5, so that the frame plates 1 are distributed in a triangular shape and are movably connected, constructing an overall frame structure. Next, the triangular frame is placed at a suitable position around the yaw motor brake, using its stable triangular structure to initially position the brake. When measuring the brake gap, a suitable feeler gauge 3 is selected from the spare feeler gauges 3 according to the estimated gap size. The insert 7 on the outer surface of the feeler gauge 3 is aligned with the insert sleeve 6 inside the frame plate 1. Because the magnet A8 on the lower surface of the insert 7 and the magnet B9 on the inner side of the insert sleeve 6 attract each other, the insert 7 can quickly slide into the insert sleeve 6 to complete the initial fixation. At the same time, the tension spring 10 inside the insert 7 is in a stretched state, driving the limiting block 11 to slide along the inside of the insert 7 until the limiting block 11 is inserted into the limiting hole 12 on the side of the insert sleeve 6 and the through hole 13 on the side of the frame plate 1, further securing the feeler gauge 3 on the frame plate 1. Then, install feeler gauges 3 in the inserts 6 in the middle of the three sets of frame plates 1. The operator measures the brake gap using feeler gauges 3 and records the gap data at three different positions. If the measurement data shows that the brake gap does not meet the standard requirements, adjustment is required. The operator uses the appropriate tools to tighten or loosen the brake bolts 4 according to the measurement data. During this process, the triangular frame structure can assist the operator in observing and fine-tuning the brake from three directions to ensure that the brake is subjected to uniform force during the adjustment. After the adjustment is completed, measure the brake gap again using feeler gauges 3. If the gap still does not meet the standard, repeat the above adjustment steps until the brake gap meets the requirements. After the measurement and adjustment work is completed, press the limit block 11 to make it overcome the tension of the tension spring 10 and disengage from the limit hole 12. Then, the feeler gauges 3 can be pulled out from the inserts 6. Finally, unscrew the bolts 4 and nuts 5, separate the frame plate 1 from the connecting block 2, and disassemble and store the tooling for future use.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
