Description

Technical Field

[0001] This application relates to the field of hoisting and construction technology, and in particular to a wind turbine hub hoisting execution system. Background Technology

[0002] In wind turbine hub hoisting, the hub needs to be turned and lifted using a combination of main and auxiliary lifting tools. The reliability of the connection between the hub and the lifting tools, as well as the coordination between the tools, directly affects the safety and efficiency of the hoisting. Existing lifting tools often rely on simple hooks or bolts for connection, which can easily lead to inaccurate positioning and loose connections. Furthermore, some lifting tools lack designs adapted to the hub's structure, resulting in unstable hub posture during hoisting. Simultaneously, the lack of targeted auxiliary protective structures during hoisting makes it difficult to provide secondary protection in case of unexpected situations with the lifting tools, posing safety hazards and failing to meet the high requirements for stability and safety in wind turbine hub hoisting.

[0003] Existing lifting tools for wind turbine hubs have low positioning accuracy and poor connection stability, and lack suitable auxiliary protection structures. The safety of coordinated lifting between lifting tools is insufficient, which can easily lead to loss of hub attitude control.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The wind turbine hub hoisting execution system described in this application, by setting up a hoisting mechanism, a first connecting member, a second connecting member, and a lifting mechanism, can first install and fix three lifting seats to the surface of the wind turbine hub body by connecting bolts when hoisting the wind turbine hub body. Then, the two ends of the three first annular lifting ropes are respectively connected and fixed to the universal lifting beam and connecting ring through the first connecting member and the second connecting member. Finally, the main hoisting equipment can be started to realize the rapid hoisting of the wind turbine hub body. Thus, the hoisting execution system can achieve precise positioning and connection by adapting the three lifting seats to the wind turbine hub body, improving the connection stability and positioning accuracy between the hoisting mechanism and the wind turbine hub body, while enhancing the safety of the hoisting process, ensuring the stability of the wind turbine hub body's posture during the hoisting process, and improving the hoisting efficiency.

[0029] 2. The wind turbine hub hoisting execution system described in this application, by setting a second connecting member, allows for the connection of the bottom end of the first annular hoisting rope to the hoisting ring after the hoisting base is installed. The connecting frame can be pressed downwards by hand, causing the hoisting ring to enter the connecting frame. This allows the hoisting ring to squeeze the sliding pressure plate, causing the sliding pressure plate to move upwards inside the connecting frame. When the sliding pressure plate moves upwards, it drives two straight toothed plates to move upwards. When the straight toothed plates move upwards, they drive two toothed discs to rotate. The rotation of the toothed discs drives the rotating shaft to rotate. The rotation of the rotating shaft, under the action of two first bevel gears, drives the vertical shaft to rotate. The rotation of the vertical shaft, under the action of two second bevel gears, drives the transverse threaded column to rotate. The rotation of the transverse threaded column, under the action of the internal threaded sleeve, drives the extension plate to move outwards. This causes the two extension plates to move simultaneously towards the center, sealing the bottom of the connecting frame, thereby achieving the connection. The frame and lifting ring are quickly connected. During the upward movement of the straight toothed plate, the plate can be inserted into the locking groove and squeeze the rectangular airbag column in the locking groove. This allows the air inside the rectangular airbag column to enter the sealing cavity, thereby pushing the piston limit column outward. When the piston limit column aligns with the limit groove, it automatically inserts into the limit groove on the straight toothed plate, achieving automatic locking of the straight toothed plate and the sliding pressure plate. When it is necessary to disassemble the connecting frame and lifting ring, the pressure relief valve can be used to release the pressure inside the sealing cavity, allowing the air in the sealing cavity to be automatically discharged. Under the action of the return spring, the piston limit column is automatically reset, releasing the limit on the straight toothed plate. This allows the sliding pressure plate to automatically reset under the action of the return spring. This eliminates the need for bolts and nuts in the connection between the connecting frame and the lifting ring, further improving lifting efficiency. Attached Figure Description

[0061] Example 2

[0062] Based on Example 1, referring to Figures 6 to 12 And unlike Example 1, the following is true:

[0063] Please refer to this carefully. Figure 6 , Figure 7 The second connector 205 includes a connecting frame 2053 disposed on the surface of the lifting ring 207. A partition plate 2054 is fixedly disposed on the inner wall of the connecting frame 2053.

A first rectangular hole and a second rectangular hole are respectively opened on both sides of the connecting frame 2053.

[0064] Specifically, the bottom end of the first annular suspension rope 202 can pass through the interior of the connecting frame 2053 and be located above the partition plate 2054, thereby achieving the connection and fixation between the first annular suspension rope 202 and the connecting frame 2053. Moreover, the setting of the second rectangular hole facilitates the sliding pressure plate 2055 to slide up and down.

[0065] Please refer to this carefully. Figure 7 , Figure 8 The second connector 205 also includes a sliding pressure plate 2055 slidably disposed on the inner wall of the two second rectangular holes. The inner wall of each of the two second rectangular holes is fixedly provided with a slide rod 2056. The upper surface of the sliding pressure plate 2055 is provided with sliding holes that are slidably connected to the surfaces of the two slide rods 2056 respectively. The surface of the slide rod 2056 is fitted with a return spring 2057. The two ends of the return spring 2057 are fixedly connected to the inner bottom wall of the second rectangular hole and the lower surface of the sliding pressure plate 2055 respectively.

[0066] Specifically, when the sliding pressure plate 2055 moves upward, it can drive the return spring 2057 to stretch, thereby facilitating the quick reset of the sliding pressure plate 2055 during disassembly.

A transverse threaded post 2060 is rotatably provided on the inner wall of the rectangular groove. A cylindrical cavity corresponding to the transverse threaded post 2060 is provided at the end of the extension plate 2059. An internal threaded sleeve 2061 that is threadedly connected to the outer surface of the transverse threaded post 2060 is fixedly provided on the inner wall of the cylindrical cavity, and a limiting block is fixedly provided at the end of the transverse threaded post 2060.

[0068] Specifically, the extension plate 2059 can automatically extend or retract outward or inward by rotating the transverse threaded column 2060 and under the action of the internal threaded sleeve 2061.

[0069] Please refer to this carefully. Figure 9 , Figure 11Both ends of the sliding pressure plate 2055 are fixedly provided with straight toothed plates 2062. The inner wall of the first rectangular hole is rotatably provided with a rotating shaft 2063.

The bottom end of the vertical shaft 2065 and the surface of the transverse threaded column 2060 are both fixedly provided with a second bevel gear 2067 that meshes with each other.

[0070] Specifically, the movement of the spur gear 2062 can drive the gear disk 2064 to rotate, the rotation of the gear disk 2064 drives the rotating shaft 2063 to rotate, the rotation of the rotating shaft 2063 drives the vertical shaft 2065 to rotate under the action of the two first bevel gears 2066, and the rotation of the vertical shaft 2065 drives the transverse threaded column 2060 to rotate under the action of the two second bevel gears 2067.

[0071] Please refer to this carefully. Figure 9 , Figure 12 The inner top wall of the first rectangular hole has a strip-shaped opening extending into the second rectangular hole. The straight toothed plate 2062 is slidably connected to the inner wall of the strip-shaped opening. The inner top wall of the second rectangular hole has a locking groove 2068 corresponding to the straight toothed plate 2062. A rectangular airbag column 2069 is fixedly mounted on the inner top wall of the locking groove 2068. A sealing cavity is formed on the inner side wall of the locking groove 2068. A piston limiting column 2070 is slidably mounted on the inner wall of the sealing cavity. The top surface of 2062 is provided with a limiting groove 2071 that is adapted to the end of the piston limiting post 2070. The end of the piston limiting post 2070 is fixed with a retraction spring 2072 to the inner wall of the sealing cavity. The surface of the rectangular airbag post 2069 is provided with a connecting pipe 2073 extending into the interior of the sealing cavity. The inner wall of the sealing cavity is provided with a pressure relief pipe 2074 extending to the outer surface of the connecting frame 2053, and the end of the pressure relief pipe 2074 is provided with a pressure relief valve.

[0072] Specifically, when it is necessary to disassemble the connecting frame 2053 and the lifting ring 207, the pressure relief valve can be used to relieve the pressure inside the sealing cavity, so that the air in the sealing cavity can be automatically discharged. Under the action of the return spring 2072, the piston limit post 2070 is automatically reset, releasing the limit on the straight tooth plate 2062, so that the sliding pressure plate 2055 can be automatically reset under the action of the return spring 2057.

[0073] In this embodiment, by setting the second connector 205, after the installation of the hanging bracket 201 is completed, when connecting the bottom end of the first annular lifting rope 202 to the lifting ring 207, the connecting frame 2053 can be pressed downwards by hand, so that the lifting ring 207 enters the connecting frame 2053. This allows the lifting ring 207 to press against the sliding pressure plate 2055, causing the sliding pressure plate 2055 to move upwards inside the connecting frame 2053. When the sliding pressure plate 2055 moves upwards, it can drive the two straight toothed plates 2062 to move upwards. When the straight toothed plates 2062 move upwards, they can drive the two... The rotation of the gear disc 2064 drives the rotation of the shaft 2063. The rotation of the shaft 2063, under the action of the two first bevel gears 2066, drives the vertical shaft 2065 to rotate. The rotation of the vertical shaft 2065, under the action of the two second bevel gears 2067, drives the horizontal threaded column 2060 to rotate. The rotation of the horizontal threaded column 2060, under the action of the internal threaded sleeve 2061, drives the extension plate 2059 to move outward. This causes both extension plates 2059 to move simultaneously towards the center, sealing the bottom of the connecting frame 2053, thereby achieving the connection of the connecting frame 2063. The 53 ring 207 is quickly connected to the lifting ring 207. During the upward movement of the straight toothed plate 2062, it can insert into the locking groove 2068 and compress the rectangular airbag column 2069 within the locking groove 2068, causing air from the rectangular airbag column 2069 to enter the sealing cavity. This pushes the piston limiting column 2070 outward. When the piston limiting column 2070 aligns with the limiting groove 2071, it automatically inserts into the limiting groove 2071 on the straight toothed plate 2062, achieving automatic locking of the straight toothed plate 2062. The pressure relief valve can be used to release the pressure inside the sealing cavity, allowing the air inside the sealing cavity to be automatically discharged. Under the action of the return spring 2072, the piston limit column 2070 is automatically reset, releasing the limit on the straight tooth plate 2062. This allows the sliding pressure plate 2055 to automatically reset under the action of the return spring 2057, thus avoiding the use of bolts and nuts between the connecting frame 2053 and the lifting ring 207, further improving the lifting efficiency.
