Description

Technical Field

[0001] This utility model belongs to the technical field of wind power tower construction platform, specifically relating to a construction platform for wind power towers. Background Technology

[0002] Wind turbine towers, as key supporting structures for wind turbine generators, typically reach heights of tens or even hundreds of meters. Construction platforms are the core operational carriers for tower construction, maintenance, and repair. With the booming development of the wind power industry, the design and function of construction platforms are constantly being innovated to meet increasingly stringent safety and operational requirements. Wind turbine tower construction platforms are crucial facilities in the construction process of wind turbine generators. Their design must balance safety, flexibility, and construction efficiency to adapt to the construction needs of towers of different heights, diameters, and in complex environments. Wind energy is an inexhaustible, clean, and renewable resource generated by nature. Among existing renewable energy sources, wind energy is undoubtedly the most competitive and is currently one of the key new energy sources being developed and utilized both domestically and internationally. Wind turbine towers primarily serve a supporting role in wind turbine generators, while also absorbing generator vibrations. Construction platforms are required during the initial material preparation, welding, and sandblasting processes of wind turbine towers, as well as during the installation of internal components.

[0003] Currently, the guardrails surrounding the top of existing wind turbine tower construction platforms are a crucial safety barrier for workers, effectively reducing the risk of accidental falls from heights by establishing physical protective boundaries. However, traditional wind turbine tower construction platform guardrails have significant design limitations. Their height is usually a uniform, fixed value, failing to adequately consider the varying protective needs arising from differences in worker height, thus reducing the safety of workers on wind turbine tower construction platforms. Utility Model Content

[0004] The purpose of this invention is to provide a construction platform for wind turbine towers, aiming to address the issue that existing wind turbine tower construction platforms rely heavily on guardrails at the top for worker safety. These guardrails, while crucial for ensuring worker safety, effectively reduce the risk of accidental falls from heights by establishing a physical protective boundary. However, traditional wind turbine tower construction platform guardrails have significant design limitations. Their height is typically a fixed, uniform value, failing to adequately consider the varying heights of workers and the resulting changes in protection requirements, thus compromising worker safety on the wind turbine tower construction platform.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction platform for a wind turbine tower, including a fixed platform, with multiple lifting lugs distributed in a ring on the top of the fixed platform, and four fixed protective railings fixedly connected to the top of the fixed platform, with connecting seats fixedly connected to the inner walls of the four fixed protective railings.

[0006] A threaded rod is inserted through the top of the connecting seat, and a threaded connecting sleeve is threadedly connected to the outer wall of the threaded rod. A connecting frame is fixedly connected to the outer wall of the threaded connecting sleeve. A movable protective guardrail is fixedly connected to the end of the connecting frame away from the threaded connecting sleeve. A guide groove is opened on the outer wall of the connecting seat, and an adjustment knob is fixedly connected to one end of the threaded rod.

[0007] As a preferred construction platform for a wind turbine tower according to this utility model, the through end of the threaded rod forms a rotating connection structure with the inner bottom of the connecting seat through a bearing.

[0008] As a preferred construction platform for a wind turbine tower according to this utility model, the end of the connecting frame away from the threaded connecting sleeve can extend through a guide groove to the outside of the connecting seat.

[0009] As a preferred construction platform for a wind turbine tower according to this utility model, the outer wall of the fixed protective railing is fixedly connected with two guide rails, and the two guide rails are symmetrically distributed.

[0010] As a preferred construction platform for a wind turbine tower according to this utility model, the end of the movable protective railing is located inside the guide rail.

[0011] As a preferred construction platform for a wind turbine tower according to this utility model, the movable protective railing can form a sliding connection structure with the fixed protective railing through two guide rails.

[0012] As a preferred construction platform for a wind turbine tower according to this utility model, the surface of the fixed platform is bonded with multiple anti-slip strips, and the surface of the lifting lug is provided with lifting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By adjusting the knob to rotate the threaded rod counterclockwise, the threaded connecting sleeve on its outer wall can drive the connecting frame to move upward along the guide groove. As the connecting frame moves, one end of it will drive the fixedly connected movable protective railing to move upward as well. Conversely, by adjusting the knob to rotate the threaded rod clockwise, the threaded connecting sleeve on its outer wall can drive the connecting frame to move downward along the guide groove. As the connecting frame moves, one end of it will drive the fixedly connected movable protective railing to move downward as well. Thus, the height of the movable protective railing can be adjusted through the above structure, thereby enhancing the protective effect on the construction platform.

[0015] By installing guide rails on the outer wall of the fixed protective railing, and with the end of the movable protective railing located inside the guide rails, the movable protective railing can play a guiding role when it is raised or lowered. It can also effectively limit the horizontal sway of the movable protective railing, ensuring that it can maintain a stable protective state even in strong winds at high altitudes. Furthermore, the anti-slip strips can improve the anti-slip effect on the fixed platform. Attached Figure Description

[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. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The present invention provides the following technical solution: a construction platform for a wind turbine tower, including a fixed platform 1, a plurality of lifting lugs 2 distributed in a ring on the top of the fixed platform 1, four fixed protective railings 3 fixedly connected to the top of the fixed platform 1, and connecting seats 4 fixedly connected to the inner walls of the four fixed protective railings 3.

[0024] A threaded rod 5 is inserted through the top of the connecting seat 4. A threaded connecting sleeve 6 is threadedly connected to the outer wall of the threaded rod 5. A connecting frame 7 is fixedly connected to the outer wall of the threaded connecting sleeve 6. A movable protective guardrail 8 is fixedly connected to the end of the connecting frame 7 away from the threaded connecting sleeve 6. A guide groove 9 is opened on the outer wall of the connecting seat 4. An adjustment knob 10 is fixedly connected to one end of the threaded rod 5.

[0025] Preferably, the through end of the threaded rod 5 forms a rotating connection structure with the inner bottom of the connecting seat 4 through a bearing, and the end of the connecting frame 7 away from the threaded connecting sleeve 6 can extend through the guide groove 9 to the outside of the connecting seat 4.

[0026] In practical use, by adjusting knob 10 to rotate threaded rod 5 counterclockwise, threaded connecting sleeve 6 connected to its outer wall threaded connection can drive connecting frame 7 to move upward along guide slide 9. As connecting frame 7 moves, one end of it will drive the fixedly connected movable protective guardrail 8 to move upward together. Conversely, by adjusting knob 10 to rotate threaded rod 5 clockwise, threaded connecting sleeve 6 connected to its outer wall threaded connection can drive connecting frame 7 to move downward along guide slide 9. As connecting frame 7 moves, one end of it will drive the fixedly connected movable protective guardrail 8 to move downward together. Thus, the height of movable protective guardrail 8 can be adjusted through the above structure to enhance the protective effect on the construction platform.

[0027] It should be noted that the four fixed protective railings 3 are arranged in pairs opposite each other, and the height of the movable protective railings 8 on each side can be adjusted individually by adjusting knob 10.

[0028] Preferably, the outer wall of the fixed protective railing 3 is fixedly connected to two guide rails 11, and the two guide rails 11 are symmetrically distributed. The end of the movable protective railing 8 is located inside the guide rails 11. The movable protective railing 8 can form a sliding connection structure with the fixed protective railing 3 through the two guide rails 11. The surface of the fixed platform 1 is bonded with multiple anti-slip strips 12, and the surface of the lifting lug 2 is provided with lifting holes 13.

[0029] It should be noted that the anti-slip strip 12 is made of serrated rubber material with staggered triangular protrusions on the surface. The height of the protrusions has been ergonomically optimized to provide sufficient friction while avoiding discomfort caused by prolonged walking by workers.

[0030] In practical use, by installing guide rails 11 on the outer wall of the fixed protective rail 3, and with the end of the movable protective rail 8 located inside the guide rails 11, the movable protective rail 8 can play a guiding role when it is raised or lowered, and can also effectively limit the swaying of the movable protective rail 8 in the horizontal direction, ensuring that it can maintain a stable protective state in the high-altitude strong wind environment. In addition, the anti-slip strips 12 can improve the anti-slip effect on the fixed platform 1.

[0031] Working principle: First, by adjusting knob 10 to rotate the threaded rod 5 counterclockwise, the threaded connecting sleeve 6 connected to its outer wall threadedly moves the connecting frame 7 upward along the guide groove 9. As the connecting frame 7 moves, one end of it will drive the fixedly connected movable protective railing 8 upward together. Conversely, by adjusting knob 10 to rotate the threaded rod 5 clockwise, the threaded connecting sleeve 6 connected to its outer wall threadedly moves the connecting frame 7 downward along the guide groove 9. As the connecting frame 7 moves, one end of it will drive the fixedly connected movable protective railing 8 downward together. Thus, through the above-mentioned... The structure can adjust the height of the movable protective railing 8 to enhance the protective effect on the construction platform. The height of the movable protective railing 8 on each side can be adjusted individually by adjusting the knob 10. By installing the guide rail 11 on the outer wall of the fixed protective railing 3, and with the end of the movable protective railing 8 located inside the guide rail 11, it can play a guiding role when the movable protective railing 8 is raised or lowered. It can also effectively limit the swaying of the movable protective railing 8 in the horizontal direction, ensuring that it can maintain a stable protective state in the high-altitude strong wind environment. Furthermore, the anti-slip strip 12 can improve the anti-slip effect on the fixed platform 1.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
