Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically an adjustable angle ring-shaped work platform for the maintenance of concrete towers of wind turbines. Background Technology

[0002] With the development of the wind power industry, the number of wind turbines is gradually increasing. The towers of wind turbines that have been in use for a long time are prone to damage and need to be repaired. However, the existing wind turbines are quite tall, requiring the use of aerial work platforms to maintain and repair the towers. In addition, the radius of the concrete tower varies with the height, which means that the higher the operator goes, the farther away the work platform is from the tower, making it difficult to get close for repairs, increasing the repair risk and prolonging the repair process. Therefore, there is a need for an adjustable angle ring work platform for the repair of concrete towers of wind turbines. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide an adjustable-angle circular working platform for the maintenance of concrete towers of wind turbines. The platform's circumference can be adjusted according to changes in the tower's radius to ensure that operators can always get close to the tower for maintenance, thereby improving maintenance efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable angle annular working platform for the maintenance of concrete towers of wind turbines, comprising multiple baskets, one end of each basket being connected to the other end via a connecting member, and the other end being connected to the other via a rotating shaft, the multiple baskets being connected end to end via the connecting member, the connecting member comprising a fixing plate and a crossbar, the fixing plate being fixedly connected to the basket and located on both sides of the basket, the fixing plate having an insertion hole, the crossbar having a fixing hole, and the insertion hole and the fixing hole being connected by bolts.

[0005] In some embodiments, both the insertion hole and the fixing hole are provided with multiple holes.

[0006] In some embodiments, the suspended platform includes a frame, a concave footboard is laid inside the frame, and a support leg is provided at the bottom of the frame.

[0007] In some embodiments, the suspended basket is provided with a lifting frame, and the lifting frame is spaced apart, with lifting ropes connected to the lifting frame.

[0008] In some embodiments, the basket is equipped with a rope drive device, a fall protection device, a wind speed monitor, and an emergency braking system.

[0009] In some embodiments, a roller is rotatably connected inside the support leg, and the outer surface of the roller extends beyond the range of the support leg.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This utility model, through the cooperation of multiple suspended baskets and connecting parts, can adjust the overall circumference of the platform by changing the fixed position between the fixed plate and the crossbar in the connecting parts when the distance between the platform and the tower changes. This ensures that the operator is always close to the tower on the platform, facilitating maintenance and improving maintenance efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] See Figure 1-4 An adjustable-angle circular work platform for the maintenance of concrete towers of wind turbines includes multiple suspended baskets 1. One end of each suspended basket 1 is connected to the other end via a connecting piece 2, and the other end is connected to the other via a rotating shaft. The multiple suspended baskets 1 are connected end to end via the connecting piece 2. The connecting piece 2 includes a fixing plate 21 and a crossbar 22. The fixing plate 21 is fixedly connected to the suspended basket 1 and is located on both sides of the suspended basket 1. The fixing plate 21 has a socket 211, and the crossbar 22 has a fixing hole 221. The socket 211 and the fixing hole 221 are connected by bolts. The suspended basket 1 is equipped with a rope drive device, a fall protection device, a wind speed monitor, and an emergency braking system. In operation, the operator enters the suspended platform 1, and then the entire platform is lifted using a rope drive device. The lifting and lowering of the platform is controlled by a fall arrestor, wind speed detector, and emergency braking system. These components are existing high-altitude work infrastructure and will not be elaborated upon here. When the operator moves the platform upwards to maintain cracks high on the wind turbine tower, the distance between the platform and the tower wall needs adjustment. Taking two adjacent suspended platforms 1 as an example, the operator removes the bolts from one of the two adjacent platforms 1, and then adjusts the bolts on the other two adjacent platforms 1. Using the pivot between the two baskets as the axis, rotate another basket 1, causing the fixing plates 21 on the two baskets 1 to move closer together, thereby shortening the distance between the two baskets 1. Finally, reconnect the fixing plates 21 and the crossbar 22, which have had their bolts removed, with bolts. By doing this, the distance between the two adjacent baskets 1 on the entire platform is readjusted, thereby changing the overall circumference of the platform to adapt to the changes in the tower's radius. The operator can also pull out the bolts on the two adjacent baskets 1 and adjust the two fixing plates 21 at the same time, so that the two baskets 1 move closer together quickly. This operation can further shorten the circumference of the entire platform and improve the speed of tower maintenance operations.

[0021] In some embodiments, multiple insertion holes 211 and multiple fixing holes 221 are provided. The cooperation of multiple insertion holes 211 and multiple fixing holes 221 allows the operator to adjust the platform's circumference radius according to changes in the tower's diameter. The operator pulls out the pre-inserted bolts, adjusts the distance between the two suspended baskets 1, and then inserts the bolts into the corresponding insertion holes 211 and fixing holes 221, thereby ensuring the stability of the entire platform.

[0022] In some embodiments, the suspended platform 1 includes a frame 11, with concave step stools 12 laid inside the frame 11, and support legs 13 provided at the bottom of the frame 11. In use, the operator enters the suspended platform 1 in advance and can move freely within the multiple suspended platforms 1 via the concave step stools 12, facilitating the maintenance of the tower. The support legs 13 can prevent the suspended platform 1 from directly contacting the ground and being worn, thereby improving the service life of the platform.

[0023] In some embodiments, the suspended platform 1 is equipped with a lifting frame 3, which is spaced apart, and lifting ropes are connected to the lifting frame 3. Operators can use the lifting ropes on the lifting frame 3 to lift or lower the entire platform, thereby quickly moving it and repairing the tower. The operation is smooth and without jamming, without any sudden stops, ensuring the safety of the operators.

[0024] In some embodiments, a roller 131 is rotatably connected within the support leg 13, and the outer surface of the roller 131 extends beyond the support leg 13. The portion of the roller 131 extending beyond the support leg 13 contacts the tower wall. When the operator controls the entire platform to move up and down, the contact between the roller 131 and the tower wall not only enables rapid movement but also reduces wear on the tower wall caused by the entire platform, preventing the tower wall from being scratched by the platform and ensuring the service life of the wind turbine.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
