Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a mounting bracket for a steel structure wind tower platform. Background Art

[0002] With the wide application of wind energy as a renewable energy source globally, wind power generation has gradually become an important part of the energy structure in many countries. Wind power generation devices are usually built in environments such as coastal areas, mountains, or wildernesses with rich wind energy resources. As the core support structure of a wind turbine generator set, the wind tower plays an important role in bearing, stabilizing, and transmitting wind energy. The stability and safety of the wind tower structure directly affect the normal operation and power generation efficiency of the entire wind power generation system.

[0003] In the structural design of a wind tower, the wind tower platform is a key component. The wind tower platform is usually installed in the upper-middle part of the wind tower and is used for maintenance personnel to stand and operate, place equipment, and perform maintenance work. Since the wind tower platform is located at a high altitude and is exposed to harsh natural environments for a long time, the stability and safety of the platform are particularly important. Therefore, how to design a mounting bracket that can not only meet the stable support of the wind tower platform but also withstand external environmental influences such as high wind loads and strong vibrations has become a key technical problem in the current wind tower structural design.

[0004] Traditional installation methods for wind tower platforms are usually fixed to the wind tower tower by direct welding or simple support structures, but these methods often have the following problems:

[0005] Insufficient structural stability: Simple welding or support structures are difficult to cope with the impact of external forces such as strong winds or earthquakes, and it is easy to cause the platform to shake or deform, affecting personnel safety and the normal operation of equipment.

[0006] Stress concentration problem: If the connection part between the platform and the wind tower tower is not designed reasonably, stress concentration is likely to occur, resulting in local structural fatigue or damage and affecting the overall stability of the wind tower.

[0007] Difficult maintenance: Once traditional welded structures are damaged or aged, the repair and replacement processes are complex and costly, affecting the maintenance efficiency and service life of the wind tower.

[0008] Therefore, it is very necessary to invent a mounting bracket for a steel structure wind tower platform. Summary of the Utility Model

The bracket realizes the efficient support, fixation and reinforcement of the platform through carefully designed structural components such as the bracket body 3, the auxiliary bracket 4 and the reinforcement bracket 6. Its working principle is as follows:

[0032] 1. Force transmission and dispersion

[0033] The bracket body 3 is fixedly installed on the outer side of the top of the wind tower tower 1 and serves as the main connection structure between the platform and the tower. The bracket body 3 transmits the weight of the wind tower platform 5 to the wind tower tower 1 through the support skeleton 31 and the fixed sleeve 32.

[0034] 2. Support and reinforcement function of the reinforcement bracket 6

[0035] The reinforcement bracket 6 provides additional reinforcement through the triangular frame formed by the first reinforcement rod 65 and the second reinforcement rod 66. This triangular structure ensures that the platform does not tilt or vibrate under wind load or other external forces through physical stability. The fixed shell 61 and the pressing cover plate 63 of the reinforcement bracket 6 are firmly connected to the wind tower tower 1 through bolts, further enhancing the overall rigidity between the bracket and the tower.

[0036] 3. Buffer and shock absorption

[0037] A buffer pad 2 is installed at the top of the wind tower tower 1. Although the buffer pad 2 is in contact with the wind tower platform 5 but not fixed, it plays a role in shock absorption and buffering. The buffer pad 2 can effectively reduce the hard contact between the platform and the tower, absorb part of the vibration and impact force from the platform, and protect the bracket body 3 and the tower structure from excessive impact loads.

[0038] 4. Multi-point fixation and balanced distribution

[0039] The design of the bracket body 3 ensures multi-point fixation. The connection points 33 and the auxiliary connection points 34 of the bracket body 3 are not only connected to the wind tower tower 1, but also fixed to the bottom surface of the wind tower platform 5 through the auxiliary support 4, so as to achieve comprehensive support and stability guarantee for the platform. This multi-point fixation method ensures that the force of the platform is evenly distributed in the entire bracket system, reducing the structural damage that may be caused by excessive force on a single part.

[0040] 5. Modular design and easy maintainability

[0041] Both the bracket body 3 and the strengthening bracket 6 are made of steel metal structures, ensuring overall high strength and corrosion resistance. The modular design of the bracket makes installation and maintenance more convenient. Each component, such as the fixed sleeve 32, the strengthening rod 65, the connecting plate 62, etc., can be independently disassembled and replaced, facilitating subsequent inspection and maintenance work.

[0042] 6. Stable and immovable structural design

[0043] The strengthening bracket 6 is fixed to the wind tower tower 1 through bolts to form a stable and immovable structure. This design ensures that under harsh weather conditions, the wind tower platform will not shift or vibrate under the action of strong winds or other external forces, guaranteeing the safety of the wind tower operation.

[0044] Summary:

[0045] The installation bracket of the steel structure wind tower platform realizes a firm connection and stable support between the platform and the wind tower tower through the reasonable configuration of key structures such as the bracket body 3, the auxiliary support 4, and the strengthening bracket 6. The bracket system has good performance in aspects such as force transmission, dispersion, buffering, and reinforcement, effectively improving the wind load resistance and service life of the wind tower platform, and providing an important guarantee for the long-term safe operation of the wind tower.
