Wind turbine installation is the process with the greatest technical difficulty, the largest investment in ship machinery and equipment, and the most adverse working conditions during offshore wind power construction. Wind turbine installation is generally divided into integral installation and split installation. Split installation is to transport the tower, nacelle, hub, and blades to the sea separately by transport barges, and use a thousand-ton crane ship to directly lift each component from the transport barge to the designated location one by one to achieve the split installation of the wind turbine. Split installation has lower requirements on the performance of the crane, can make full use of the offshore construction operation window, and is widely used in various offshore wind power projects.

One end of the screw rod 3 passes through the second side plate 12 and is connected to the motor 5.

[0009] Furthermore, the upper guide rail 14 is integrally formed with the top plate 1 , and the lower guide rail 8 is integrally formed with the bottom plate 9 , which has a simple structure and strong stability.

[0010] Furthermore, a vertical rod 7 is provided between the top plate 1 and the bottom plate 9. The vertical rod 7 is located in the middle of the bottom plate 9 and has a function of providing stable support to enhance the supporting performance of the base.

[0011] Furthermore, two limiting grooves 11 arranged parallel to the screw rod 3 are formed on the upper surface of the top plate 11 , and limiting blocks 10 matching the limiting grooves 11 are arranged on the support frame 4 corresponding to the limiting grooves 11 , and the limiting blocks 10 are slidably arranged in the limiting grooves 11 .

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The wind turbine tower hanger has a stable base, and a roller is rotatably arranged between the upper guide rail and the lower guide rail, and the roller can move between the upper guide rail and the lower guide rail; a screw mouth is arranged above the support frame, and the inner thread of the screw mouth is connected to a screw rod, and a motor is arranged at one end of the screw rod, and the motor can drive the screw rod to rotate. When the screw rod rotates, the support frame can move along the screw rod, and the support frame can be limited by the screw rod. The roller can be limited by the arrangement of the top plate and the bottom plate, and the support frame can be limited by the second arrangement through the connection of the screw rod, so that the support frame as a whole can be limited when moving, and a limiting groove is arranged on the support frame, and a limiting block is arranged on the top plate corresponding to the limiting groove. When the support frame moves, it will also be limited by the limiting groove and the limiting block, and the support frame will not tip over, thereby realizing the stable movement of the support frame.
