[0002] In recent years, concrete-steel hybrid towers have attracted wide attention for their good structural performance and development prospects, especially in high tower projects. Due to their good transportability, structural safety, stable unit operation, outstanding power generation, long service life, and low carbon emissions, they have become one of the mainstream technical trends for high towers at home and abroad. Aerial work baskets are widely used in peripheral operations such as exterior wall decoration, maintenance, and cleaning, providing workers with a stable working platform, which is somewhat dangerous. The diameter of the steel-concrete tower decreases with increasing height, and the diameter span is large. The aerial basket needs to be quickly adjusted to follow the diameter change of the steel-concrete wind turbine tower to ensure the safety and stability of the basket during peripheral operations. However, the existing aerial work basket is inconvenient to disassemble and move, and can only be used for the construction of wind turbine hybrid towers of the same height specification, resulting in a large span between the basket and the steel-concrete wind turbine tower, which is not convenient for peripheral operations and increases the risk of aerial work basket accidents.

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, the present invention includes a plurality of slides 2, a plurality of suspension platforms 1 and a transmission device; the number of the slides 2 and suspension platforms 1 is the same as the number of sides of the cross section of the fan mixing tower. Since the cross section of the fan mixing tower in this embodiment is a regular octagon, the number of the slides 2 and suspension platforms 1 is eight. The suspension platform 1 is V-shaped, and the angle of the V-shape is the same as the angle between the adjacent sides of the cross section of the fan mixing tower, which is 135°. Two sets of guide rails are provided on the suspension platform 1, and the guide rails at the opposite ends of adjacent suspension platforms are coaxial and support a slide 1. The suspension platform 1 is provided with a lifting lug for suspending the present invention. The inner end and the outer end of the corner of the suspension platform 1 are respectively provided with an inner guardrail mounting rod 1-1 and an outer guardrail mounting rod 1-2, and a telescopic guardrail is installed between two adjacent inner guardrail mounting rods 1-1 and between adjacent outer guardrail mounting rods 1-2.

[0017] The transmission device includes a plurality of winches 8, which are mounted on the bottom surface of the suspension platform 1 through a mounting seat 3, and a winch is mounted for each suspension platform 1. A steel wire rope I9 and a steel wire rope II10 are wound around the winch 8, and the winding directions of the steel wire rope I9 and the steel wire rope II10 are opposite. The two ends of the steel wire rope I9 are respectively passed around a pulley I7 and connected to the ends of the two slides supported by the suspension platform where the winch is located, which are facing the winch end, and the two pulleys I7 are installed on the suspension platform where the winch is installed. The two ends of the steel wire rope II10 are respectively passed around a pulley II4 and connected to the suspension platform where the winch is located, and the two pulleys II4 are respectively installed on two suspension platforms adjacent to the suspension platform where the winch is located.

[0018] The end of the slide 2 facing away from the winch is fixedly connected to the suspension platform where the end of the slide 2 is located through a locking pin. The other end of the slide 2 is provided with a pin hole I, and the suspension platform 1 where the other end of the slide 2 is located is provided with multiple pin holes II, and the centers of the multiple pin holes II are on a straight line, and the straight line is parallel to the moving direction of the slide. After the other end of the slide 2 is moved into place, it is connected to the suspension platform where the other end of the slide is located through a locking pin.

[0019] The present invention is raised and lowered during operation by a special lifting wire rope for the steel-mixed wind turbine tower hung on the suspension platform 1. Figure 4 As shown, the expansion principle of the present invention is as follows: the winch 8 rotates clockwise, and the expansion force is also transmitted through the wire rope I9, so that the slide 2 moves backward along the guide rail on the suspension platform on which the winch 8 is installed, so that the distance between adjacent suspension platforms 1 is increased, thereby achieving the overall expansion of the present invention and adapting to the increase in the outer size of the wind turbine tower.

[0020] like Figure 5As shown, the contraction principle of the present invention is as follows: the winch 8 rotates counterclockwise, and the contraction force is transmitted through the wire rope II 10, pulling the two suspension platforms 1 adjacent to the suspension platform installed with the winch 8 toward the suspension platform installed with the winch 8; the slide 2 moves forward on the guide rail of the suspension platform 1 installed with the winch 8, so that the distance between adjacent suspension platforms 1 is reduced, thereby achieving the overall contraction of the present invention and adapting to the reduction of the outer size of the wind turbine tower.
