Description

Technical Field

[0001] The utility model relates to the technical field of blade weight measurement, in particular to a fixing device for measuring the weight of an assembled blade. Background Art

[0002] The fan blade is one of the core components of the fan. The weight and height changes of the fan blade will cause changes in the overall fan, which will lead to various problems. The inconsistent weight of the blade will affect the dynamic balance of the fan, causing vibration and noise during the operation of the fan, and even damage the mechanical structure of the fan in severe cases.

[0003] The most common way for wind turbine manufacturers to measure the weight of wind blades is to use electronic scales or balances for weighing. This method is simple and easy, can accurately measure the weight of the wind blades, and can quickly obtain data. Weighing can ensure the consistency of the blade weight, which helps to improve the performance and stability of the wind turbine. However, there are also some disadvantages to using electronic scales or balances to measure the weight of wind blades. First, due to the large and irregular shape and size of the wind blades, they may be unstable and sway back and forth when placed on an electronic scale or balance, resulting in inaccurate weighing results. Secondly, when weighing a large number of wind blades, they need to be placed on an electronic scale or balance one by one for measurement, which is time-consuming, labor-intensive, and inefficient.

The bottom plate 11 is fixed on the desktop 1, providing a stable installation foundation for the blade fixing tool 2. This is the core part of the device, which is used to fix and support the assembled blade to be measured: the double bearing seat 28 is arranged Installed on the base plate 11, it provides stable support for the rotating shaft 22. The rotating shaft 22 is inserted in the middle of the double bearing seat 28, allowing the upper cover 26 and the lower cover 27 to rotate freely around it, which is convenient for the placement and removal of the blades. The hinge 23 is rotatably connected so that the cover can be flexibly opened and closed. This design facilitates the operator to quickly and safely fix or release the blade. The electromagnet generates magnetism when energized, which is used to firmly adsorb the blade to ensure stability during the measurement process. The upper electromagnet 25 is fixed in the upper cover 26, and the lower electromagnet 24 is fixed in the lower cover 27. When the cover is closed, they work together to fix the blade in the tooling. Using electromagnets instead of traditional mechanical clamping methods can achieve faster and more precise fixation, while also reducing the damage to the blade that may be caused by uneven clamping force.

[0021] like Figure 1 As shown, in this embodiment, a rotating shaft motor 21 is arranged under the desktop 1 opposite to the blade fixing tool 2; the rotating shaft motor 21 arranged under the desktop 1 opposite to the blade fixing tool 2 plays an important role in driving rotation, automatic control, measurement support, improving measurement efficiency and reducing operation difficulty in the fixing device for measuring the weight of the assembled blade.

[0022] like Figure 1 As shown, in this embodiment, legs 12 are cross-arranged under the table top 1; the cross-arranged legs 12 can provide a stable support for the table top 1, ensuring that the entire device remains stable during operation and will not shake or tilt due to external forces. This stability is essential for accurate blade weight measurement; the cross-leg 12 design can increase the load-bearing capacity of the table top 1. Since the blade fixing device may be used to support and fix heavier assembled blades, the legs 12 need to have sufficient strength and stability to bear these weights.

[0023] like Figure 1 As shown, in this embodiment, an electric control box 3 is arranged on the other side below the desktop 1; the electric control box 3 arranged on the other side below the desktop 1 can ensure that the entire fixing device for measuring the weight of the assembled blade can operate stably, efficiently and safely.

[0024] like Figure 1 As shown, in this embodiment, the electric control box 3 below the desktop 1 is provided with a PLC part 31 and a switch power supply 32; the PLC (Programmable Logic Controller) is the core control element in the electric control box 3, which is responsible for the automation control logic of the entire system. The PLC can receive input signals, perform corresponding logic operations, and output control signals according to the preset program to drive external devices such as the shaft motor 21; the PLC can collect various data of the system in real time, such as current, voltage, temperature, etc., and perform necessary processing, such as filtering, conversion, etc., to ensure the accuracy and reliability of the data; the PLC has a storage unit inside, which can store programs, data and intermediate results written by the user.

When the switch power supply 32 is in the on state, the equipment in the electric control box 3 will be supplied with power; when the switch power supply 32 is turned off, the power is cut off to ensure that the equipment is in a safe state.

[0025] like Figure 1 As shown, in this embodiment, the double bearing seat 28 is fixed to the base plate 11 by fastening screws; one of the main functions of the fastening screws is to fix and position the double bearing seat 28. By tightly connecting the double bearing seat 28 with the base plate 11, it is ensured that the bearing seat will not move or deflect during operation, thereby ensuring the stability and accuracy of the blade fixing tool 2; the double bearing seat 28 needs to bear the weight of the bearing and the blade and various forces generated during the processing, such as cutting force, spindle inertia force, centrifugal force, etc. The function of the fastening screws is to transfer these loads to the base plate 11 to ensure the stability and safety of the entire structure; long-term operation or vibration may cause the connection between the bearing seat and the base plate 11 to loosen. The fastening screws effectively prevent the loosening of the bearing seat by providing sufficient clamping force, thereby ensuring the continuous and stable operation of the equipment; the design of the fastening screws makes the installation and removal of the double bearing seat 28 simple and quick. When the bearing seat needs to be replaced or repaired, it can be easily removed by simply loosening the fastening screws, and vice versa.

[0026] Working principle: Through the design of the double bearing seat 28 and the rotating shaft 22, the blade fixing tool 2 can rotate around the rotating shaft 22 to meet the blade operation requirements at different angles; the upper flip cover 26 and the lower flip cover 27 are rotatably connected through the hinge 23, and can be easily opened and closed to achieve the fixing and release of the blade. When the blade needs to be fixed, the blade is tightly clamped between the upper flip cover 26 and the lower flip cover 27 by the suction force of the electromagnet; when the blade needs to be released, the suction force is released by controlling the on and off of the electromagnet, so that the upper flip cover 26 and the lower flip cover 27 are opened; an upper electromagnet 25 is fixed in the upper flip cover 26, and a lower electromagnet 24 is fixed in the lower flip cover 27. When the electromagnets are powered, they will generate a strong suction force to firmly fix the blades between the upper and lower flaps 27, ensuring that the blades will not move or shake during the measurement process; the weighing sensor can be installed under the blade fixing fixture 2, and when the blades are fixed, the sensor will measure and output the weight data of the blades; a rotating shaft motor 21 is arranged under the table 1, and the PLC part 31 in the electric control box 3 can realize automatic control of the motor and other components. For example, the angle, speed and duration of rotation can be preset through the PLC program to realize automatic rotation and measurement of the blades.

[0027] In summary, the fixing device for measuring the weight of assembled blades, through the design of the double bearing seat 28 and the rotating shaft 22, the blade fixing tool 2 can rotate around the rotating shaft 22, so as to facilitate the operation and measurement of the blade from different angles; the upper flip cover 26 and the lower flip cover 27 are connected by the hinge 23, so that the fixing and releasing process of the blade becomes simple and quick, and can adapt to blades of different sizes and shapes; the setting of the upper electromagnet 25 and the lower electromagnet 24 can ensure that the blade is stably fixed during the measurement process, and prevent measurement errors caused by movement or shaking.
