Description

Technical Field

[0001] This invention relates to the field of wind turbine internal component installation equipment, and more particularly to aluminum alloy scaffolding for installing large-diameter wind turbine internal components. Background Technology

[0002] As the wind power industry develops towards larger-scale offshore and onshore operations, the diameter of wind turbine towers has increased from the traditional 3-4 meters to over 6 meters (offshore wind turbine towers can reach 8 meters and above). The internal space of large-diameter wind turbine towers is complex, and traditional steel ramps are too heavy and have poor adaptability to meet the requirements of convenience and safety for high-altitude operations.

[0003] Wind power projects have tight schedules, and the installation of internal components (such as cables, ladders, platform supports, etc.) requires frequent erection of temporary work platforms. The lightweight nature of aluminum alloy scaffolding can reduce reliance on hoisting equipment and lower transportation and installation costs.

[0004] When using the above technology, the following technical problems were found in the existing technology: First, the traditional fixed scaffolding is limited by the constant length design and cannot match the diameter difference between the upper and lower sections of the tower, which leads to the need to frequently change scaffolding of different specifications during operation, which significantly increases the complexity of operation and labor cost. Secondly, the existing ladders have a fixed height. When the height of the scaffolding platform needs to be adjusted due to changes in the tower structure, the ladder components must be repeatedly disassembled and reassembled. This increases the frequency of high-altitude operations, posing safety hazards such as falling components and personnel imbalance, and makes it difficult to meet the safety specifications for modern tower installation. Therefore, we designed aluminum alloy scaffolding platforms for installing large-diameter wind tower internal components to provide an alternative technical solution to the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum alloy mounting plate for large-diameter wind turbine internals to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The internal components of the large-diameter wind tower are installed with aluminum alloy ramps, including ramps and ladders. Extension plates are slidably connected to both ends of the inner side of the ramp. Supporting guides are fixed to both ends of the bottom of each extension plate. Guide rails are provided on both sides of the bottom of the ramp. The ends of the two supporting guides that are close to each other are slidably connected to the guide rails. A fixing block is fixed to the bottom of the ramp. A bidirectional hydraulic cylinder is installed inside the fixing block at its bottom end. The output end of the bidirectional hydraulic cylinder is fixed to the supporting guide. A ladder is installed on one side of the ramp. A telescopic folding ladder is slidably connected to the inner side of the ladder. A base is rotatably connected to the bottom end of the telescopic folding ladder.

[0007] Guide rods are fixed on both sides of the bottom end of the extension plate and above the inner side of the support guide frame, and the two ends of the bottom end of the jump plate are slidably connected to the guide rods respectively.

[0008] Both sides of the two extension plates, away from the end of the jump board, are fixed with pin posts.

[0009] The top of the springboard is fixed with guardrail A on both sides, and the top of the extension board is fixed with guardrail B on both sides. The two guardrail B sides that are far apart from each other are slidably connected to guardrail A.

[0010] Among them, the bottom of the two B guardrails, which are close to each other, are provided with sliding grooves, and the inner side of the sliding grooves is slidably connected to the plank.

[0011] The escalator has U-shaped support blocks fixed at both ends on one side of the scaffolding, and a support rod fixed at the top of the escalator. The two ends of the support rod are slidably connected to the inner side of the U-shaped support block.

[0012] The escalator has an adjusting screw rotatably connected to one side, a guide groove is provided on one side inside the escalator, a transmission block is slidably connected to the inner side of the guide groove, one end of the transmission block is fixed to the telescopic folding ladder, the outer side of the adjusting screw is threadedly connected to the transmission block, and a handwheel is fixed to the bottom end of the adjusting screw.

[0013] A U-shaped block is fixed to the bottom of the other side of the escalator. A sliding plate is slidably connected to the inner side of the U-shaped block. A limit pin is fixed to one end of the sliding plate. The end of the limit pin away from the sliding plate passes through the escalator and is slidably connected to the telescopic folding ladder.

[0014] The telescopic folding ladder has several limiting holes on one side inside, and one end of the limiting pin is slidably connected to the corresponding limiting hole.

[0015] The limiting pin is fitted with a spring on its outer side, one end of the spring is fixed to the escalator, and the other end of the spring is fixed to a sliding plate.

[0016] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the present invention can adjust the length of the scaffolding by adjusting the length of the scaffolding, and the bidirectional hydraulic cylinder drives the support guide, guide rod and extension plate to extend along both ends of the scaffolding. The length of the scaffolding and extension plate can be flexibly adjusted according to the diameter difference between the upper and lower sections of the tower, adapting to the diameter of different positions of the tower, reducing the preparation time before construction, increasing the construction efficiency of the responsible personnel, and making the device applicable to the installation of internal components of wind towers of various specifications. The escalator's connection to the ramps and its adjustable telescopic design allows it to extend and retract according to the height of the ramps and extension boards. Rotating the handwheel drives the adjusting screw, making it easy to adjust the length of the telescopic ladder to accommodate different heights above the ground and ramps, greatly increasing the ease of climbing for workers and reducing climbing difficulty and physical exertion. The overlapping and sliding of guardrails A and B forms an effective protection, preventing workers from accidentally falling. After the escalator and telescopic folding ladder are adjusted to their positions, the spring drives the limit pin to engage with the limit hole, improving the stability of both and preventing workers from deviating while climbing. This effectively reduces safety hazards during construction and provides reliable safety for workers. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] Firstly, traditional fixed scaffolding is limited by its constant length design and cannot match the diameter difference between the upper and lower sections of the tower. This results in the need to frequently change scaffolding of different specifications during operation, which significantly increases the complexity of operation and labor costs. Secondly, existing ladders have a fixed height. When the height of the scaffolding platform needs to be adjusted due to changes in the tower structure, the ladder components must be repeatedly disassembled and reassembled. This increases the frequency of high-altitude operations, posing safety hazards such as falling components and personnel imbalance, and makes it difficult to meet the safety standards for modern tower installation. To solve this technical problem, this invention provides aluminum alloy scaffolding platforms for installing large-diameter wind tower internal components.

[0024] For details, please refer to Figures 1-10 The aluminum alloy scaffolding platform for installing the internal components of the large-diameter wind tower specifically includes: scaffolding platform 1 and ladder 2. Extension plates 5 are slidably connected to both ends of the inner side of scaffolding platform 1. Support guides 3 are fixed to both ends of the bottom of extension plates 5. Guide rails are provided on both sides of the bottom ends of scaffolding platform 1. The ends of the two support guides 3 that are close to each other are slidably connected to the guide rails. A fixing block 9 is fixed to the bottom of scaffolding platform 1. A two-way hydraulic cylinder 10 is installed at the bottom inside the fixing block 9. The output end of the two-way hydraulic cylinder 10 is fixed to the support guide 3. Ladder 2 is installed on one side of scaffolding platform 1. Telescopic folding ladder 13 is slidably connected to the inner side of ladder 2. A base 15 is rotatably connected to the bottom of telescopic folding ladder 13.

[0025] The large-diameter wind tower internal component installation aluminum alloy scaffolding provided by this invention is adjustable according to the diameter difference between the upper and lower sections of the tower. Two extension plates 5 extend along the length of the scaffolding 1, so that the lengths of the extension plates 5 and the scaffolding 1 can be adjusted and unfolded according to the diameter of the tower. This effectively adjusts the length between the scaffolding 1 and the extension plates 5 directly according to the diameter difference between the upper and lower sections of the tower, thereby increasing the practicality and flexibility of the device.

[0026] Example 1 Please see Figure 1-5 This invention provides a technical solution: an aluminum alloy scaffolding board for installing internal components of a large-diameter wind tower, including a scaffolding board 1 and a ladder 2. The scaffolding board 1 is integrally formed from high-strength aluminum alloy material, with anti-slip textures on the surface. The texture depth is 3mm to increase friction and prevent workers from slipping. Extension plates 5 are slidably connected to both ends of the inner side of the scaffolding board 1. Support guides 3 are fixed to both ends of the bottom of the extension plates 5. Guide rails are provided on both sides of the bottom ends of the scaffolding board 1. The ends of the two support guides 3 that are close to each other are slidably connected to the guide rails. A fixing block 9 is fixed to the bottom of the scaffolding board 1. The output end of a bidirectional hydraulic cylinder 10 is fixed to the support guide 3. A ladder 2 is installed on one side of the scaffolding board 1. A telescopic folding ladder 13 is slidably connected to the inner side of the ladder 2. A base 15 is rotatably connected to the bottom of the telescopic folding ladder 13. When construction work needs to be carried out inside the tower, the length of the extension plate 5 is adjusted according to the diameter difference between the upper and lower sections of the tower. The two extension plates 5 extend along the length of the scaffold 1, so that the length of the extension plate 5 and the scaffold 1 can be adjusted according to the diameter of the tower. This effectively adjusts the length between the scaffold 1 and the extension plate 5 directly according to the diameter difference between the upper and lower sections of the tower, thereby increasing the practicality and flexibility of the device. Guide rods 4 are fixed on both sides of the bottom end of the extension plate 5 and above the inner side of the support guide 3. The two ends of the bottom end of the jump plate 1 are slidably connected to the guide rods 4 respectively. The outer side of the guide rods 4 slides with the bottom end of the jump plate 1, thereby improving the stability and smoothness of the sliding of the extension plate 5 and greatly increasing the flexibility of the extension plate 5 to effectively meet the sliding adjustment effect between the jump plate 1 and the extension plate 5. Therefore, the output end of the bidirectional hydraulic cylinder 10 drives the support guide 3, guide rod 4 and extension plate 5 to extend along the length of both ends of the scaffold 1, so as to effectively adjust the diameter according to different positions of the tower and increase the construction efficiency of the personnel in charge. Both sides of the two extension plates 5 away from the end of the jump plate 1 are fixed with pins 6, which can be effectively engaged with the tower through the pins 6, so that the device can be assembled at different height positions inside the tower. A guardrail 7 is fixed on both sides of the top end of the scaffold 1, and B guardrail 8 is fixed on both sides of the top end of the extension plate 5. The two B guardrails 8 are slidably connected to the A guardrail 7 on the side that is far away from each other. The bottom of the two B guardrails 8 is provided with a sliding groove at the bottom of the side that is close to each other. The inner side of the sliding groove is slidably connected to the scaffold 1. Specifically, the overlapping sliding between guardrail A (7) and guardrail B (8) effectively protects workers and increases their safety.

[0027] Example 2 Please see Figure 6-10 The present invention provides a technical solution: an aluminum alloy scaffolding is installed in the internal components of a large-diameter wind tower. U-shaped support blocks 11 are fixed at both ends of the middle of one side of the scaffolding 1. A support rod is fixed at the top of the ladder 2. The two ends of the support rod are slidably connected to the inner side of the U-shaped support block 11. The escalator 2 and base 15 are effectively installed on one side of the scaffold 1 by the support rod, so that the scaffold 1 and extension plate 5 can be extended and retracted according to the height. The extension plate 5 and the telescopic folding ladder 13 can be slidably adjusted, thereby increasing the convenience of construction for workers. Meanwhile, an anti-tipping block is provided on the edge of the base 15. The block is 10cm high and can prevent the telescopic folding ladder 13 from tipping over during use. An adjusting screw 12 is rotatably connected to one side of the escalator 2. A guide groove is provided on one side inside the escalator 2. A transmission block is slidably connected to the inner side of the guide groove. One end of the transmission block is fixed to the telescopic folding ladder 13. The outer side of the adjusting screw 12 is threadedly connected to the transmission block. A handwheel is fixed to the bottom end of the adjusting screw 12. A U-shaped block 14 is fixed to the bottom of the other side of the escalator 2. A slide plate 16 is slidably connected to the inner side of the U-shaped block 14. A limit pin 18 is fixed to one end of the slide plate 16. The end of the limit pin 18 away from the slide plate 16 passes through the escalator 2 and is slidably connected to the telescopic folding ladder 13. Specifically, when the scaffold 1 and the escalator 2 are installed inside the tower, the adjusting screw 12 is rotated by rotating the handwheel. The adjusting screw 12 adopts a trapezoidal thread, which has high transmission efficiency and self-locking performance. The adjusting screw 12 drives the transmission block and the telescopic folding ladder 13 along one end of the escalator 2, thereby effectively adjusting according to the height of the scaffold 1 and the escalator 2, so as to increase the convenience of climbing for the staff. Several limiting holes 17 are provided on one side of the interior of the telescopic folding ladder 13. One end of the limiting pin 18 is slidably connected to the corresponding limiting hole 17. A spring 19 is sleeved on the outside of the limiting pin 18. One end of the spring 19 is fixed to the ladder 2, and the other end of the spring 19 is fixed to the slide plate 16. Meanwhile, safety rope hooks are installed on both sides of the telescopic folding ladder 13, so that workers can fix the safety rope to the hooks when climbing, further ensuring safety; Furthermore, when the escalator 2 and the telescopic folding ladder 13 are adjusted to the position of the ground and the ramp 1, the spring 19 will cause the slide plate 16 and the limit pin 18 to pass through the escalator 2 and engage with the corresponding limit hole 17, thereby improving the stability between the escalator 2 and the telescopic folding ladder 13 and preventing workers from deviating during the climbing process, which could lead to safety hazards.

[0028] The process of using the aluminum alloy scaffolding for installing large-diameter wind tower internals provided by this invention is as follows: During construction work inside the tower, due to the diameter difference between the upper and lower sections of the tower, the output end of the bidirectional hydraulic cylinder 10 drives the support guide 3, guide rod 4, and extension plate 5 to extend along the length of both ends of the scaffolding 1. The outer side of the guide rod 4 slides against the bottom end of the scaffolding 1, ensuring that the extension plate 5 slides stably and smoothly. The length of the extension plate 5 and the scaffolding 1 can be adjusted and unfolded according to the tower diameter, and then the device is fixed at different heights inside the tower by locking the pin 6. The A guardrail 7 on both sides of the top of the scaffold 1 overlaps and slides with the B guardrail 8 on both sides of the top of the extension plate 5 to protect the workers and ensure construction safety. The escalator 2 is installed by sliding a support rod at its top to a U-shaped support block 11 on one side of the scaffold 1. After the scaffold 1 and escalator 2 are assembled inside the tower, rotating the handwheel drives the adjusting screw 12 to rotate. The adjusting screw 12 is threadedly connected to the transmission block, which drives the transmission block and the telescopic folding ladder 13 to move along the escalator 2. The length of the telescopic folding ladder 13 is adjusted according to the height of the scaffold 1 and escalator 2. After adjustment to the appropriate position, the spring 19 elastically drives the sliding plate 16 and the limiting pin 18 to pass through the corresponding limiting holes 17 of the escalator 2 and the telescopic folding ladder 13 and engage, ensuring the stability of the escalator 2 and the telescopic folding ladder 13 and preventing deviation when workers climb, thereby improving the practicality of the device while ensuring construction safety.

[0029] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
