Description

Technical Field

[0001] This utility model belongs to the field of offshore wind power generation technology, and in particular relates to an auxiliary guiding device for wind turbine hoisting. Background Technology

[0002] As a crucial component of clean energy, wind power generation faces complex installation environments, high technical challenges, and substantial costs. The high-altitude flange connection between the wind turbine nacelle and the tower is a critical step in the hoisting operation, and its accuracy directly impacts the overall installation quality and long-term operational safety of the wind turbine. Offshore operations are often affected by adverse factors such as wind, waves, and currents, causing the nacelle to sway and shift during hoisting, making it difficult to quickly and accurately align the bottom flange with the top flange of the tower. During wind turbine installation, especially when the rudder is connected to the tower, traditional guide structures are susceptible to impact, compression, or wear when not in operation (such as during ground placement or transportation), leading to structural deformation or damage and affecting subsequent installation accuracy and safety. Furthermore, the connection between the rudder and tower flange of offshore wind turbines requires extremely high coaxiality and positional accuracy. Existing guide devices often lack effective adaptive calibration mechanisms, leading to deviations during installation and requiring repeated adjustments, increasing installation time and risk. Therefore, we provide an auxiliary guide device for wind turbine installation to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this utility model is to provide a wind turbine hoisting auxiliary guide device. By using a positioning ring plate, a spring and a movable ring plate in combination, the second conical part can be easily stored, thus avoiding damage to the structure. At the same time, the second conical part and the first conical part work together to achieve the calibration of the rudder.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a wind turbine hoisting auxiliary guide device, including an assembly ring plate and a movable ring plate; a vertical part 1 is fixed to the lower end face of the assembly ring plate, a conical part 1 is fixed to the lower end face of the vertical part 1, a vertical part 2 is fixed to the lower end face of the movable ring plate and inserted into the inner side of the vertical part 1, a conical part 2 is fixed to the lower end face of the vertical part 1 and inserted into the inner side of the conical part 1, a positioning ring plate is provided directly above the movable ring plate, and a spring is provided between the positioning ring plate and the movable ring plate.

[0005] The present invention is further configured such that a mounting hole is provided through the side wall of the positioning ring plate, the positioning ring plate is installed at the inner end face of the rudder flange by bolts passing through the inside of the mounting hole, the movable ring plate is at the port position of the rudder flange, and the assembly ring plate cylinder is installed at the flange end of the tower by bolts.

[0006] The present invention is further configured such that a limit rod is fixed at the position of each set of springs on the lower end face of the positioning ring plate, and a stop hole is opened at the position of the limit rod on the upper end face of the movable ring plate. The lower end face of the limit rod is inserted into the corresponding stop hole, and each limit rod passes through the inside of the corresponding spring.

[0007] The present invention is further configured such that both ends of the spring are fixed with abutment ring plates sleeved on the limiting rod, and each set of abutment ring plates abuts against the end faces of the movable ring plate and the positioning ring plate respectively.

[0008] The present invention is further provided that the lower end face of the movable ring plate is provided with a plurality of circular openings that are respectively connected to the inside of the baffle hole, and a circular plate is provided inside each of the circular openings.

[0009] The present invention is further configured such that the lower end face of the limiting rod is provided with a screw hole, and the upper end face of the circular plate is fixed with a screw that is spirally inserted in the screw hole.

[0010] This utility model has the following beneficial effects: 1. When the rudder is transferred to the upper position of the tower, the rudder and the tower are initially aligned. Therefore, when the rudder is transferred downwards to the tower, the second conical part will be inserted into the assembly flange. As it continues to move downwards, the second conical part will come into contact with the inner wall of the first conical part. Through the pushing of the first conical part and the second conical part, the second conical part is gradually corrected, thereby guiding and calibrating the rudder and controlling the flange on the rudder to be accurately assembled on the flange of the tower.

[0011] 2. In this invention, the positioning ring plate is installed inside the flange opening of the rudder, so that the movable ring plate is located at the end of the flange opening of the rudder. Therefore, when the rudder is placed on the ground, the second conical part is compressed and moves into the flange opening of the rudder. The second conical part will drive the second vertical part to move synchronously. The movable ring plate will compress the spring. Therefore, when installing the rudder, the second conical part will be stored, which can effectively prevent damage to the second conical part and the second vertical part.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 Please see Figures 1 to 5 This utility model is a wind turbine hoisting auxiliary guide device. Through the cooperation of positioning ring plate 3, spring 304 and movable ring plate 2, it is convenient to store the second conical part 202 and avoid damage to the structure. At the same time, the cooperation of the second conical part 202 and the first conical part 102 realizes the calibration of the rudder.

[0021] Specifically, the assembly ring plate 1 and the movable ring plate 2 are assembled. A vertical part 101 is fixed to the lower end face of the assembly ring plate 1, and a tapered part 102 is fixed to the lower end face of the vertical part 101. A vertical part 201 is fixed to the lower end face of the movable ring plate 2 and inserted into the inner side of the vertical part 101. A tapered part 202 is fixed to the lower end face of the vertical part 101 and inserted into the inner side of the tapered part 102. A positioning ring plate 3 is provided directly above the movable ring plate 2. A spring 304 is provided between the positioning ring plate 3 and the movable ring plate 2. An installation hole 301 is provided through the side wall of the positioning ring plate 3. The positioning ring plate 3 is bolted through the interior of the installation hole 301 and installed on the inner end face of the rudder flange. The movable ring plate 2 is located at the port of the rudder flange. The assembly ring plate 1 is bolted to the flange end of the tower.

[0022] The operation process of this embodiment is as follows: Using the above-described structure, the positioning ring plate 3 is installed inside the flange opening of the rudder, so that the movable ring plate 2 is positioned at the end of the flange opening of the rudder. Therefore, when the rudder is placed on the ground, the conical part 202 is compressed, causing it to move inwards towards the flange opening of the rudder. This causes the conical part 202 to move synchronously with the vertical part 201. The movable ring plate 2 compresses the spring 304. Therefore, when installing the rudder, the conical part 202 is retracted, effectively preventing damage to both the conical part 202 and the vertical part 201. Thus, after the rudder is lifted by a crane... Spring 304 pushes the movable ring plate 2 to move steadily downward, so that the vertical part 201 and the conical part 202 are completely removed from the flange opening of the rudder. When the rudder is transferred to the upper position of the tower, the rudder and the tower are initially aligned. Therefore, when the rudder is transferred downward to the tower, the conical part 202 will be inserted into the assembly flange. As it continues to move downward, the conical part 202 will come into contact with the inner wall of the conical part 102. Through the pushing of the conical part 102 on the conical part 202, the conical part 202 is gradually corrected, thereby guiding and calibrating the rudder and controlling the flange on the rudder to be accurately assembled on the flange of the tower.

[0023] Example 2 Please see Figure 2 and Figure 3 Based on Example 1, the movable ring plate 2 can be easily disassembled and replaced by using the screw 206 and the screw hole 303 together.

[0024] Specifically, a limit rod 302 is fixed at the lower end of the positioning ring plate 3 corresponding to the position of each set of springs 304. A stop hole 204 is opened at the upper end of the movable ring plate 2 corresponding to the position of the limit rod 302. The lower end of the limit rod 302 is inserted into the corresponding stop hole 204. Each limit rod 302 passes through the inside of the corresponding spring 304. Both ends of the spring 304 are fixed with abutting ring plates 305 sleeved on the limit rod 302. Each set of abutting ring plates 305 abuts against the end faces of the movable ring plate 2 and the positioning ring plate 3. The lower end of the movable ring plate 2 is provided with multiple round openings 203 that communicate with the inside of the stop hole 204. A round plate 205 is provided inside each round opening 203. A screw hole 303 is opened at the lower end of the limit rod 302. A screw 206 is fixed at the upper end of the round plate 205 and screwed in the screw hole 303.

[0025] The operation process of this embodiment is as follows: With the above structure, when the movable ring plate moves upward inside the rudder flange, the movable ring plate will move along the limit rod through the stop hole. When replacing the movable ring plate, multiple circular plates can be rotated out of the circular opening, so that the screw can be disengaged from the screw hole. Thus, the circular plates no longer limit the movable ring plate, and the movable ring plate can be disconnected from the limit rod.
