Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower manufacturing technology, specifically to a wind turbine tower ladder connection component. Background Technology

[0002] Wind turbine tower ladders are primarily used for the vertical transport of maintenance personnel inside the wind turbine tower. Traditional tower ladder designs typically involve welding connections, fixing internal components to the tower's inner wall, and then connecting the ladder to these components. However, this method results in a large number of welding points for the internal components, requiring multiple sets of components to be welded along the ladder path from the tower base to the top. This not only leads to poor fatigue resistance but also makes the tower susceptible to cracking or even breakage under long-term alternating loads. Furthermore, maintenance personnel must verify each welding point individually during periodic inspections of the internal components, impacting maintenance efficiency. Therefore, how to avoid or reduce welding structures on the tower to improve the fatigue resistance of the steel tower has been a major technical challenge we have been working on. Utility model content: To address the shortcomings of existing technologies, this utility model provides a wind turbine tower ladder connection assembly. This assembly significantly reduces the number of welding points for internal accessories, improves the fatigue resistance of the wind turbine tower, reduces the workload of maintenance personnel, and improves maintenance efficiency.

[0003] To achieve the above objectives, this utility model provides the following technical solution: A wind turbine tower ladder connection assembly includes a ladder, a connecting frame, a connector, a wire rope, a wire rope clamp, a strong magnetic connector, a tower platform, and a wire rope connector. One or more tower platforms are installed and fixed inside the tower. Wire rope connectors are bolted to the two side surfaces of each tower platform. Wire rope connectors on adjacent tower platforms are connected by a wire rope. The outer side of the ladder is fixed to one end of the connecting frame. The other end of the connecting frame is bolted to the connector. A wire rope clamp is installed on the connector, and the clamp is fixed to the wire rope. A strong magnetic connector is magnetically fixed to the inner wall of the tower. The strong magnetic connector is hinged to the end of the connector.

[0004] Preferably, the ladder is fixed with support frames on both sides of the tower platform; the middle part of the support frame is bolted to the tower platform; the middle part of the support frame is provided with a slot, and the tower platform is inserted into the slot.

[0005] Preferably, a double-ended screw is movably inserted into the step beam of the ladder, and one end of the connecting frame is provided with a through hole. The through hole of the connecting frame passes through the end of the double-ended screw and is tightened and fixed by a nut. The end of the connecting frame connected to the ladder is provided with a U-shaped bending structure.

[0006] Preferably, a safety guide rail is welded to the back of the ladder at a position corresponding to the inner wall of the tower.

[0007] Preferably, the tower has one or more tower platforms inside, and the bottom of the tower platform is fixed to the internal accessories with bolts.

[0008] Preferably, two sets of wire rope connecting seats are provided on one side of the tower platform; a wire rope is connected between each set of wire rope connecting seats, and the two wire ropes are located on both sides of the ladder near the inner wall of the tower.

[0009] The beneficial effects of this utility model are: This connecting assembly relies on the tower platform as a ladder support, ensuring support strength while using a strong magnetic connector to replace the original welded internal accessories. During each maintenance, operators only need to inspect the welding points of the internal accessories at each tower platform location, significantly reducing the number of welding connection points. The strong magnetic base uses magnetic attraction to the inner wall of the tower, reducing the support pressure on the tower platform. Attached image description: To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] In the diagram, 1 is the ladder, 2 is the connecting frame, 3 is the connector, 4 is the wire rope, 5 is the wire rope clamp, 6 is the strong magnetic connector, 7 is the tower platform, 8 is the wire rope connector, 9 is the support frame, 10 is the double-ended screw, 11 is the safety rail, and 12 is the tower. Detailed implementation method: like Figure 1-3As shown, a wind turbine tower ladder connection assembly ensures sufficient support strength while significantly reducing the number of welded internal accessories within the tower 12. One or more tower platforms 7 are installed and fixed inside the tower 12. Wire rope connectors 8 are bolted to the two side platforms of the tower platform 7; adjacent tower platforms 7 are connected by wire ropes 4 via wire ropes 4; the outer side of the ladder 1 is fixed to one end of a connecting frame 2; the other end of the connecting frame 2 is bolted to a connector 3; wire rope clamps 5 are installed on the connector 3, clamping and fixing the wire ropes 4; the ladder 1 provides some support strength through the wire ropes 4. Although the support strength of the tower platform 7 is sufficient to support the ladder 1, to further reduce the support pressure on the tower platform 7, a strong magnetic connector 6 is magnetically fixed to the inner wall of the tower; the strong magnetic connector 6 is hinged to the end of the connector 3.

[0014] like Figure 1-3 As shown, furthermore, to ensure the stability of the ladder 1, support frames 9 are fixed on both sides of the ladder 1 corresponding to the tower platform 7; the middle of the support frame 9 is bolted to the tower platform 7; the middle of the support frame 9 has a slot, into which the tower platform 7 is inserted, and the support frame 9 provides some support strength for the ladder 1. A double-headed screw 10 is movably inserted into the step beam of the ladder 1, and one end of the connecting frame 2 has a through hole, through which the end of the double-headed screw 10 is passed and tightened by a nut; the end of the connecting frame 2 connected to the ladder 1 has a U-shaped bending structure; a safety guide rail 11 is welded to the back of the ladder 1 corresponding to the inner wall of the tower, and the safety rope of the operator is connected to the safety guide rail 11 to ensure the personal safety of the operator during maintenance. Two sets of wire rope connecting seats 8 are provided on one side of the tower platform 7; a wire rope 4 is connected between each set of wire rope connecting seats 8, and the two wire ropes 4 are located on both sides of the ladder 1 near the inner wall of the tower.

[0015] like Figure 1 , 2 As shown, the tower 12 contains one or more tower platforms 7, the bottom of which is bolted to internal attachments. Only the tower platforms 7 are fixed by welded internal attachments; maintenance personnel can inspect the welded internal attachments at the location of the tower platforms 7 each time, compared to inspecting all welded internal attachments from the end of the ladder 1 to the top of the ladder 1. This improves maintenance efficiency while ensuring the strength and stability of the ladder. Unless otherwise described, the fixing methods mentioned above all use welding or threaded fastening techniques commonly used by industry professionals.
