Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a tower structure with a detachable hoisting platform and its hoisting method. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source that has been utilized by humans for a long time, mainly through windmills for pumping water and grinding grain. People are interested in how to use wind to generate electricity. Wind power generation is very environmentally friendly, and wind energy reserves are enormous, therefore it is receiving increasing attention from countries around the world.

[0003] Wind is one of the pollution-free energy sources. Moreover, it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous regions, and plateaus lacking water, fuel, and with inconvenient transportation, utilizing wind power in accordance with local conditions is highly suitable and has great potential. Offshore wind power is an important area of ​​renewable energy development, a vital force driving technological progress and industrial upgrading in wind power, and an important measure to promote energy structure adjustment. my country has abundant offshore wind energy resources. Accelerating the construction of offshore wind power projects is of great significance for helping coastal areas control air pollution, adjust energy structure, and transform economic development patterns.

[0004] The wind turbine tower is the core structure of a wind turbine, typically constructed from welded steel. Installation begins with material preparation and processing according to design requirements, followed by segmental assembly and welding. The tower installation must ensure verticality and stability to guarantee the normal operation of the wind turbine. After tower installation, a series of accessories need to be installed, including platforms, railings, ladders, and lightning rods. These accessories are crucial for the normal operation and maintenance of the wind turbine.

[0005] Currently, the installation and assembly of wind power towers is quite difficult. The tower bodies of wind power towers are usually stacked from bottom to top. Due to their height, hoisting is difficult, and it is hard to hoist the tower bodies to the upper level. Moreover, the already installed tower bodies do not provide sufficient load-bearing capacity, making the hoisting and assembly of components quite challenging. Summary of the Invention

[0006] The purpose of this invention is to provide a tower structure with a detachable hoisting platform and its hoisting method, in order to solve the problems mentioned in the background art, such as the difficulty in installing and assembling wind power towers, where the tower bodies of wind power towers are usually stacked from bottom to top, and due to their height, hoisting is difficult, making it hard to hoist the tower bodies to the upper level, and the already installed tower bodies do not easily provide load-bearing capacity, thus making the hoisting and assembly of components difficult.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tower structure for a detachable hoisting platform, comprising:

[0008] The tower body has combined connecting parts at its upper and lower ends;

[0009] A tower platform, which is detachably connected to the side wall of the tower body, and the tower platform is provided with a main hoist passage hole for the main hoist to pass through;

[0010] A pulley is provided on the upper surface of the tower platform on the side away from the tower body.

[0011] Preferably, the tower platform is provided with a platform ear plate at one end near the tower body, and a tower ear plate is provided on the side wall of the tower body. The tower ear plate and the platform ear plate are positioned correspondingly, and the tower ear plate and the platform ear plate are connected by a platform pin.

[0012] Preferably, the platform ear plate includes a platform body and triangular support blocks disposed on the front and rear sides of the lower surface of the platform body. The platform ear plate is disposed at one end of the platform body facing the tower body and at one end of the triangular support blocks facing the tower body. The main hoist is provided on the platform body through a hole.

[0013] Preferably, the tower platform is made of stainless steel, and the thickness of both the platform body and the triangular support block is not less than 3cm.

[0014] Preferably, the tower platform and the tower body are connected by bolts.

[0015] A method for hoisting a tower structure using a detachable hoisting platform, the specific steps of which are as follows:

[0016] The first tower section, the first tower platform, and the main winch were installed in place using the main crane.

[0017] The main hoist retracts its boom, and then the main winch is used to hoist the second tower section onto the first tower platform. The main winch extends its boom, and then the second tower section is installed.

[0018] The main crane installed the second tower platform section;

[0019] The main crane retracts its boom, and the main winch lifts the main crane to the second tower platform.

[0020] The main crane will install the third tower section, and so on, installing the fourth and fifth tower sections, and then the nacelle, hub, and blades;

[0021] Then, using the ground-based main winch, the tower platform on each tower body was dismantled step by step, and the wind turbine was installed.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By altering the airflow direction and changing the relative positions of each platform, vortex-induced vibrations can be resisted, preventing tower collapse. The platform is designed for heavy-duty operation and can accommodate helicopters or drones. Using helicopters or drones to transport spare parts for mountain wind turbine maintenance can save on road construction costs. This significantly reduces the manufacturing cost of offshore wind turbines. The reasons are as follows: A) Reduced installation costs: utilizing the platform eliminates the need to rent large cranes, allowing for the installation of the entire wind turbine. B) This hoisting method can be used for subsequent replacement of large components in the wind turbine aftermarket.
