[0018] See also Figure 1-2The utility model provides a technical solution: a wind blade hoisting adjustable cable wind device, including a crane boom 10, and also includes a crossbeam 1, a circulating hoisting system 2, a single-blade clamp 3, a computer control system 4, a fixed pulley additional power system 5, a gripper 6, a cable wind rope 7, a first slideway system 8, a second slideway system 9, and a crane boom 10. The second slideway system 9 is fixedly installed on the crossbeam 1, the fixed pulley additional power system 5 is slidably connected with the second slideway system 9 and locked through the gripper 6, the fixed pulley additional power system 5 is fixedly connected with the single-blade clamp 3 through the cable wind rope 7, the single-blade clamp 3 is used to clamp the fan blade 11, the first slideway system 8 is fixedly installed on the crane boom 10 and is arranged along the length direction of the crane boom 10, the crossbeam 1 is slidably arranged on the first slideway system 8 and controls the crossbeam 1 to move along the first slideway system 8 through the circulating hoisting system 2, and the computer control system 4 is installed on the crossbeam 1.
[0019] Specifically, two fixed pulley auxiliary power systems 5 are provided and are symmetrically arranged on the beam 1 with the crane arm 10 as the axis, which can improve the stability of the hoisting of the wind turbine blades 11, and the fixed pulley auxiliary power system 5 can be adjusted and moved on the beam 1, and can be suitable for hoisting of wind turbine blades 11 with different stability.
[0020] Specifically, the computer control system 4 is electrically connected to the circulating hoisting system 2 and controls the operation of the circulating hoisting system 2. The computer control system 4 controls the operation of the circulating hoisting system 2 to control the sliding of the beam 1 along the first slide system 8. The computer control system 4 can select a plc control system, and the circulating hoisting system 2 is a common prior art in this field.
[0021] Specifically, a displacement sensor is provided in the computer control system 4 for detecting the relative heights of the crossbeam 1 and the fan blades 11 in real time. During the process of hoisting the fan blades 11 by the crane, the real-time height of the fan blades 11 is transmitted through the displacement sensor built into the computer control system 4. The computer control system 4 controls the circulating winch system 2 to keep the crossbeam 1 and the fan blades 11 at the same height and lift them synchronously, thereby maintaining the stability of the fan blades 11 during the hoisting process.

[0024] A specific application example of this embodiment is:
[0025] When the device is in use, before the crane lifts the blades of the wind turbine, the position of the fixed pulley additional power system 5 on the beam 1 is adjusted based on the size of the hoisted wind turbine blades, so that the two cable wind ropes 7 are kept at the same height and parallel to each other during the lifting process, and the two fixed pulley additional power systems 5 are fixed to the beam 1 through the gripper 6 on the beam 1. During the hoisting of the wind turbine blades, the built-in displacement sensor of the computer control system 4 detects the relative height of the wind turbine blades and the beam 1 in real time, and is connected to the circulating hoisting system 2 through a signal transmission device. The circulating hoisting system 2 accurately drives the beam 1 to move up and down along the first slide system 8. The blade centroid height and the height information of the beam 1 transmitted by the computer control system 4 are used to control the circulating hoisting system 2 so that the beam 1 and the blade are kept at the same height and lifted synchronously, thereby ensuring the stability of the hoisting of the wind turbine blades.
