[0002] With the continuous development of the global offshore wind power industry, a variety of offshore wind turbines have emerged on the market. The installation technology of wind turbines is also constantly improving. At present, the two most commonly used and most economical methods for wind turbine installation are: Integral installation: The three blades and the hub are first assembled into a whole at a land dock or on a ship, and then transported to the wind farm for overall hoisting and assembly with the main engine.

[0014] The present invention has the following beneficial effects: 1.

[0027] In a preferred embodiment: the rubber seat 306 is fixedly assembled by fixing bolt four 307 and connecting plate 305, the sliding seat 303 is slidably connected by sliding groove 304 and sliding groove 206, four groups of abutting airbags 309 are respectively arranged at the arc surface 308 on both sides of the two groups of rubber seats 306, and the abutting airbags 309 are fixedly assembled by arc surface 308 and rubber seat 306, the four groups of abutting airbags 309 are all connected with connecting pipe one 310, and an air valve is provided at the connection between connecting pipe three 312 and connecting pipe two 311.

[0028] In the above structure, the rubber seat 306 is fixedly assembled by the fixing bolt 307 and the connecting plate 305, so that a plurality of rubber seats 306 can be replaced, and the abutting airbags 309 can be replaced separately when damaged, thereby reducing the maintenance cost of the equipment, and the sliding seat 303 is slidably connected with the sliding groove 304 and the sliding groove 206, so that the position of the abutting component 3 at the driving component 2 can be changed by a certain angle, and when the plurality of abutting components 3 abut the blade body 5, the abutting angles of the plurality of abutting components 3 to the blade body 5 can be changed by moving the abutting components 3, thereby increasing the application range of the equipment; It is understandable that in some specific use environments, the driving component 2 and the abutting component 3 may also be connected by a fixed assembly method; In actual use, the two groups of semicircular fixing rings 109 are sleeved on the outer wall of the blade body 5, and the two groups of semicircular clamping rings 104 are sleeved on the outer wall of the semicircular fixing ring 109, and the rotating frame component 1 is connected and fixed, and the sliding seat 303 is slidably sleeved through the sliding groove 304 and the sliding groove 206, so that the position of the abutting component 3 at the driving component 2 is changed by a certain angle, thereby making the several abutting components 3 adaptively abut against the blade body 5, and then controlling the several telescopic rods 204 through the controller, so that the telescopic rods 204 drive the abutting component 3 to move to one side of the blade body 5 through the moving plate 205, and then connecting the air pump and the several connecting pipes 312 through the hose, so that the abutting airbag 309 is inflated, and then the gap between the rubber seat 306 and the blade body 5 is filled with the abutting airbag 309 in the expanded state, thereby realizing the lifting of the blade body 5 by the equipment; When the crane drives the lock buckle 102 to move upward through the cable, the arc ring 101 rotates between the rotating shaft 105 and the semicircular clamping ring 104, and the semicircular clamping ring 104 transmits the tension transmitted by the cable to the plurality of driving components 2 through the semicircular fixing ring 109. The driving components 2 are used to transmit force to the support plate 301 and the reinforcing ribs 302, so that the tension transmitted by the cable through the equipment is transmitted to the blade body 5 through the rubber seat 306 and the abutting airbag 309 located on both sides of the support plate 301. By increasing the contact width between the equipment and the blade body 5, the problem that when the blade is hoisted by using a fixing clamp, the tension applied by the cable to the fixing clamp in a non-horizontal state increases the contact surface pressure between the fixing clamp and the outer edge of the bottom of the blade, thereby causing damage to the blade is solved; On the other hand, the blade body 5 is abutted by the abutting airbag 309. When the blade body 5 is tilted, the blade body 5 is subjected to a certain displacement in opposite directions due to gravity and the abutting airbag 309. The friction between the blade body 5 and the abutting airbag 309 is used to make the outer wall of the abutting airbag 309 move along with the blade body 5 to the side where the blade body 5 moves, thereby squeezing the abutting airbag 309. The abutting airbags 309 are connected through the connecting pipe 1 310, so that the gas in the squeezed inner cavity of the abutting airbag 309 is transmitted to the inner cavity of the other groups of abutting airbags 309, thereby increasing the abutting force of the other groups of abutting airbags 309 on the blade body 5, thereby increasing the stability of the device. On the other hand, through the abutment airbag 309, the moving position between the equipment and the blade body 5 can be adjusted by the gravity of the blade body 5 during the lifting process, so that the position and angle of the abutment force applied by the rubber seat 306 and the abutment airbag 309 to the blade body 5 can be changed, thereby distributing the tension on the blade body 5, thereby solving the problem of traditional equipment directly clamping the blade body 5, resulting in deformation of the clamping force point of the blade body 5.

[0029] In a preferred embodiment, the outer walls at both ends of the reinforcing rib 302 are provided with slots 313 , and the fixing steel cables 4 are located at the positions of several slots 313 .

[0030] In the above structure, the fixing steel cable 4 is limited by the card slot 313 so that the fixing steel cable 4 will not be separated from the abutting component 3, and the fixing steel cable 4 is used to limit the abutting components 3 so that the end positions of the abutting components 3 will not be deformed.

[0031] Working principle: The lock buckle 102 is used to connect with the cable of the lifting equipment, and the arc ring 101 is rotatably connected with the rotating shaft 105 through the rotating groove 103, so that the angle between the arc ring 101 and the semicircular clamp 104 is changed, so that the tension applied by the cable through the lock buckle 102 is transmitted to the rotating shaft 105 through the arc ring 101, and then the rotating shaft 105 is transmitted to several groups of driving components 2 through the semicircular clamp 104, thereby avoiding the blade being lifted in an unfixed position when the blade is lifted by a fixing clamp in the traditional equipment. In the horizontal state, the tension applied by the cable to the fixing fixture increases the contact surface pressure between the fixing fixture and the outer edge of the bottom of the blade, thereby causing damage to the blade. On the other hand, the two groups of semicircular clamps 104 are sleeved on the outer walls of the two groups of semicircular fixing rings 109, and the connecting ends of the two groups of semicircular clamps 104 and the two groups of semicircular fixing rings 109 are staggered, so that the rotating frame component 1 can fix the plurality of driving components 2, so as to avoid the problem of position displacement of the plurality of driving components 2 during use. The two groups of semicircular fixing rings 109 are sleeved on the outer wall of the blade body 5, and the two groups of semicircular clamping rings 104 are sleeved on the outer wall of the semicircular fixing rings 109, and the rotating frame component 1 is connected and fixed, and the sliding seat 303 is slidably sleeved through the sliding groove 304 and the sliding groove 206, so that the position of the abutting component 3 at the driving component 2 is changed by a certain angle, so that the several abutting components 3 can adaptively abut and adjust the blade body 5, and then control the several telescopic rods 204 through the controller, so that the telescopic rods 204 drive the abutting component 3 to move to one side of the blade body 5 through the moving plate 205, and then connect the air pump and the several connecting pipes 312 through the hose to inflate the abutting airbag 309, so that the gap between the rubber seat 306 and the blade body 5 is filled with the abutting airbag 309 in the expanded state, so that the equipment can lift the blade body 5; When the crane drives the lock buckle 102 to move upward through the cable, the arc ring 101 rotates between the rotating shaft 105 and the semicircular clamp ring 104, and the semicircular clamp ring 104 transmits the tension transmitted by the cable to the plurality of driving components 2 through the semicircular fixing ring 109. The driving components 2 are used to transmit the force to the support plate 301 and the reinforcing ribs 302, so that the tension transmitted by the cable through the device is transmitted to the blade body 5 through the rubber seat 306 and the abutting airbag 309 on both sides of the support plate 301. By increasing the contact width between the device and the blade body 5, on the other hand, through the abutting airbag 309, the device and the blade body are During the hoisting process, the movement position of the blade body 5 can be adjusted by the gravity of the blade body 5, so that the position and angle of the abutment force applied by the rubber seat 306 and the abutment airbag 309 to the blade body 5 can be changed, thereby distributing the tension on the blade body 5, thereby solving the problem that the traditional equipment directly clamps the blade body 5, resulting in deformation of the clamping force point of the blade body 5, and solving the problem that when the blade is hoisted by the fixing clamp, the tension applied by the cable to the fixing clamp in the non-horizontal state increases the contact surface pressure between the fixing clamp and the outer edge of the bottom of the blade, thereby causing damage to the blade; On the other hand, the blade body 5 is abutted by the abutment airbag 309. When the blade body 5 is tilted, the blade body 5 is displaced in opposite directions by gravity and the abutment airbag 309. The friction between the blade body 5 and the abutment airbag 309 is utilized to make the outer wall of the abutment airbag 309 move along with the blade body 5 toward the side where the blade body 5 moves, thereby squeezing the abutment airbag 309. A plurality of abutment airbags 309 are connected through a connecting tube 310, so that the gas in the inner cavity of the squeezed abutment airbag 309 is transmitted to the inner cavity of other groups of abutment airbags 309, thereby increasing the abutment force of the other groups of abutment airbags 309 on the blade body 5, thereby increasing the stability of the equipment.
