Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower technology, and in particular to a high-altitude docking auxiliary platform for wind turbine towers. Background Technology

[0002] A wind turbine tower is the tower of a wind power generation system. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. To facilitate transportation, wind turbine towers are usually installed in sections. During the connection and installation process, the wind turbine tower sections need to be connected and then fixed with bolts.

[0003] During the docking process, auxiliary docking devices are generally used to speed up the docking efficiency. Traditional docking devices use an upper and lower deformation internal support method to keep the two towers centered, such as the docking device for wind tower installation disclosed in Chinese Patent Publication No. CN216842060U.

[0004] However, the current auxiliary docking device has a lower tensioning structure that protrudes below the platform. When the upper and lower towers dock, there is a risk of impacting this structure. After the impact, the lower tensioning structure will deform, affecting the accuracy of the docking centering. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the lower tensioning structure protruding below the platform, which poses a risk of impact to the structure when the upper and lower towers are connected. Therefore, a wind power tower high-altitude docking auxiliary platform is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an auxiliary platform for high-altitude docking of wind turbine towers:

[0008] It includes a perforated base plate, which is coupled to the interior of the upper tower via a support assembly, and a platform is slidably connected above the base plate via a drive assembly;

[0009] At least a portion of the platform is positioned opposite the upper end of the base plate, and a support assembly is installed below the platform. The support assembly is connected to the drive assembly so that when the platform moves and abuts against the base plate, the support assembly expands and positions itself within the lower tower.

[0010] Furthermore, the drive assembly includes a plurality of guide rods fixed to the base plate, the tops of the plurality of guide rods being connected together to a top plate, wherein a pusher is fixedly mounted on the top of the top plate.

[0011] Furthermore, the shaft end of the pusher extends to the bottom of the platform, a limiting plate is fixedly connected to the shaft end of the pusher, a spring is fixedly connected between the limiting plate and the platform, and a limiting block is fixedly installed on the shaft end of the pusher, the limiting block stopping below the platform.

[0012] Furthermore, the expansion assembly includes a sleeve fixed to the bottom of the platform and looped around the shaft end of the pusher;

[0013] Multiple arms are pinned to the outside of the sleeve, and multiple connecting rods are pinned to the shaft end of the pusher, with each connecting rod being pinned to the middle of each arm in sequence.

[0014] Furthermore, the support assembly includes multiple drive components fixed to the base plate, and an arc-shaped top plate is detachably connected to the shaft end of each drive component.

[0015] Furthermore, a sleeve is fixedly installed on the back end of the arc-shaped top plate, and the shaft end of the drive component is inserted into the sleeve. A positioning glass bead is embedded on the outer side of the shaft end of the drive component, and a hole adapted to the telescopic end of the positioning glass bead is opened on the outer side of the sleeve.

[0016] The wind turbine tower high-altitude docking auxiliary platform proposed in this utility model has the following advantages: the expansion support component of this utility model can move freely from the perforations in the base plate when it is in the retracted state. In addition, in the initial state, the expansion support component is retracted on top of the base plate. Thus, during the high-altitude docking of the towers, the expansion support component can be first retracted in the upper tower. When the two towers approach each other and are roughly aligned, the expansion support component is driven downward by the drive component and opened and positioned in the lower tower, so as to ensure the docking accuracy of the upper and lower towers and reduce the risk of the expansion support component being damaged by impact during the initial docking.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 As an embodiment of this utility model, it discloses a high-altitude docking auxiliary platform for wind turbine towers. Specifically, the platform includes a base plate 1 with a perforation 11. The base plate 1 is coupled to the interior of the upper tower 3 through a support component 2. A platform 5 is slidably connected above the base plate 1 through a drive component 4.

[0024] At least a portion of the platform 5 is directly opposite the upper end of the base plate 1. A support assembly 6 is also installed below the platform 5. The support assembly 6 is connected to the drive assembly 4 so that when the platform 5 moves and abuts against the base plate 1, the support assembly 6 expands and positions itself in the lower tower 3.

[0025] It should be noted that, in this embodiment, the expansion support component 6 can move freely from the perforation 11 of the base plate 1 when it is in the retracted state. In addition, in the initial state, the expansion support component 6 is retracted above the base plate 1. Thus, during the high-altitude docking of the towers, the expansion support component 6 can be first retracted into the upper tower 3. When the two towers 3 are close to each other and roughly aligned, the expansion support component 6 is driven downward by the drive component 4 and opened and positioned in the lower tower 3 to ensure the docking accuracy of the upper and lower towers, while reducing the risk of the expansion support component 6 being damaged by impact during the initial docking.

[0026] In some embodiments, the drive assembly 4 of this invention includes a plurality of guide rods 41 fixed on the base plate 1, the platform 5 slides between the plurality of guide rods 41, and a top plate 42 is connected to the top of the plurality of guide rods 41. A pusher 43 is fixedly installed on the top of the top plate 42. Preferably, in this embodiment, three guide rods 41 are provided, and the pusher 43 is preferably a hydraulic cylinder. Of course, in other embodiments, it can also be set as an electric actuator or a pneumatic cylinder. The specific choice can be made by those skilled in the art.

[0027] Furthermore, the shaft end of the pusher 43 extends to the bottom of the platform 5, and a limiting plate 44 is fixedly connected to the shaft end of the pusher 43. A spring 45 is fixedly connected between the limiting plate 44 and the platform 5.

[0028] In this embodiment, the spring 45 and the limiting plate 44 are used to achieve an elastic connection between the pusher 43 and the platform 5. Alternatively, a limiting block 46 can be fixedly installed on the shaft end of the pusher 43. The limiting block 46 stops below the platform 5 so that when the pusher 43 resets and drives the platform 5 to move upward, the limiting block bears the force and limits the upward movement of the platform 5.

[0029] Based on the above embodiments, the expansion assembly 6 in this embodiment includes a sleeve 61 fixed to the bottom of the platform 5 and sleeved around the shaft end of the pusher 43. Specifically, the limiting block 46 in this embodiment abuts against the lower part of the sleeve 61 so that when the shaft of the pusher 43 moves upward, the platform 5 can be pulled upward by the spring 45 and the limiting block 46.

[0030] Multiple arms 62 are pinned to the outside of the sleeve 61. Multiple connecting rods 63 are also pinned to the shaft end of the pusher 43. Each connecting rod 63 is pinned to the middle of each arm 62 in sequence. In addition, in order to ensure the sliding stability of the arm 62 after contacting the inner wall of the tower 3, a roller 64 can be installed on the end of the arm 62 in this embodiment. The roller 64 is slidably connected to the inner wall of the tower 3 to reduce the sliding resistance of the arm 62 when it opens.

[0031] like Figure 2 As shown, in the initial state, the pusher 43 pulls the platform 5 upward above the base plate 1 through the action of the spring 45 and the limiting block 46. At this time, the base plate 1 can be fixed inside the upper tower 3 by the support assembly 2. The tower 3 is hoisted by the hoisting equipment for high-altitude splicing. After it is roughly aligned with the lower tower 3, the positioning operation can be carried out.

[0032] Specifically, during positioning, the pusher 43 is activated first. The shaft end of the pusher 43 extends out. When the pusher 43 moves downward, the platform 5 will move downward synchronously under the elastic push of the spring 45. At this time, the connecting rod 63 on the lower side of the platform 5 and the arm 62 on the shaft end of the pusher 43 will also move downward until they move into the interior of the lower tower 3.

[0033] Since the shaft end of the pusher 43 is slidably connected to the platform 5, when the platform 5 moves down to the upper side of the base plate 1, it is stopped by the resistance of the base plate 1 and cannot continue to move. Meanwhile, the shaft end of the pusher 43 continues to extend. At this time, under the traction of the connecting rod 63, the arm 62 begins to rotate. Multiple arms 62 rotate synchronously and open up inside the lower tower 3 for center positioning, so that the upper tower 3 and the lower tower 3 are aligned in the center. After that, the upper tower 3 can be further moved down to complete the high-altitude docking. After the docking is completed, the components are reset, and then the platform can be lifted out of the current tower 3 by the hoisting equipment.

[0034] In some embodiments, the support assembly 2 of this utility model includes a plurality of driving components 21 fixed on the base plate 1. An arc-shaped top plate 22 is detachably connected to the shaft end of the driving component 21. In this embodiment, the driving component 21 is preferably a hydraulic cylinder. Of course, in other embodiments, it can also be set as an electric actuator or a pneumatic cylinder. The specific choice can be made by those skilled in the art. By driving the arc-shaped top plate 22 to push out onto the inner wall of the upper tower 3 through the driving component 21, the base plate 1 can be fixed.

[0035] In addition, in order to disassemble and maintain the arc-shaped top plate 22, a sleeve 23 is fixedly installed on the back end of the arc-shaped top plate 22 in this embodiment. The shaft end of the drive member 21 is inserted into the sleeve 23. A positioning glass bead 24 is embedded on the outer side of the shaft end of the drive member 21. The outer side of the sleeve 23 is provided with a hole 25 that matches the telescopic end of the positioning glass bead 24. In this embodiment, two positioning glass beads 24 can be provided. When it is necessary to disassemble the arc-shaped top plate 22, the arc-shaped top plate 22 and the shaft end of the drive member 21 can be separated by pressing the telescopic end of the positioning glass bead 24 to make it retract into the hole 25.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
