[0002] The wind turbine tower is the tower pole for wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1-Figure 6 As shown, an offshore wind power tower lifting device includes a mounting plate 100, a moving mechanism for moving the lifting device, the moving mechanism is located on the mounting plate 100, and also includes a clamping mechanism for clamping and lifting the tower, the clamping mechanism is located below the moving mechanism.

[0027] In this embodiment: the moving mechanism includes a slide rail 301 arranged at the upper end of the mounting plate 100, a threaded rod 303 is rotatably installed in the slide rail 301, a moving motor 302 is installed at the rotating end of the threaded rod 303, a sliding seat 305 is slidably installed in the slide rail 301, the sliding seat 305 is threadedly connected to the threaded rod 303, and two hanging rings 304 are fixed to the upper end of the slide rail 301.

[0028] In this embodiment: the clamping mechanism includes a moving frame 201 arranged at the lower end of the sliding seat 305, a guide rod 202 is fixed to the rear end of the moving frame 201, a lead screw 203 is rotatably installed at the front end, a clamping motor 204 is installed at the rotating end of the lead screw 203, two symmetrical clamping plates 205 are arranged between the guide rod 202 and the lead screw 203, the clamping plates 205 are threadedly connected to the lead screw 203, the clamping plates 205 are slidably connected to the guide rod 202, a cylinder 207 is arranged between the two clamping plates 205, a wedge-shaped clamping seat 206 is fixed to the lower end of the clamping plate 205, and an anti-sway component for reducing shaking of the cylinder 207 during transportation is arranged between the clamping seat 206 and the clamping plate 205.

[0029] The anti-sway component includes a lower oil chamber 209 arranged on the inclined surface of the clamping seat 206, a pressing plate 210 is slidably installed in the lower oil chamber 209, an anti-slip pad is provided on the surface of the pressing plate 210, a compression spring is connected between the pressing plate 210 and the lower oil chamber 209, an upper oil chamber 213 is provided at the upper end of the clamping plate 205, a sliding column 214 is slidably installed in the upper oil chamber 213, a pre-tightening spring is connected between the sliding column 214 and the upper oil chamber 213, a top block 215 is fixed to the end of the sliding column 214 close to the cylinder 207, the top block 215 is made of rubber, and the end of the top block 215 close to the cylinder 207 is an arc surface, and an oil groove 208 is opened between the upper oil chamber 213 and the lower oil chamber 209.

[0030] A support plate 211 is slidably installed at the lower end of the clamping seat 206. The two support plates 211 are inclined at one end close to each other. A cylinder 212 is provided between the support plate 211 and the clamping seat 206. The cylinder 207 of different diameters is clamped and fixed by the clamping mechanism. When the cylinder 207 tends to shake when it is hoisted, the anti-sway component is prompted to further clamp and press the upper end of the cylinder 207 to prevent the cylinder 207 from shaking. The greater the tendency of the cylinder 207 to shake, the greater the clamping force on the cylinder 207, thereby improving the stability of the cylinder 207 when it is hoisted.

[0031] Working principle: first place the cylinder 207 at the position to be lifted, then move the two clamping plates 205 to both sides of the cylinder 207, drive the clamping motor 204 to drive the lead screw 203 to rotate, drive the two clamping plates 205 to move toward each other to clamp and fix the middle cylinder 207, and the cylinder 207 will generate a reaction force on the pressing plate 210 when being clamped. At the same time, under the action of the gravity of the cylinder 207 itself, the pressing plate 210 will be pressed downward, and the pressure generated by the downward movement of the pressing plate 210 is sufficient to press the hydraulic oil inside the lower oil chamber 209 into the upper oil chamber 213 through the oil groove 208, drive the sliding column 214 in the upper oil chamber 213 to drive the top block 215 to move close to the upper end of the cylinder 207, and drive the two top blocks 215 to clamp and press the upper end of the cylinder 207.

[0032] Then, the moving motor 302 is driven to drive the threaded rod 303 to rotate, drive the sliding seat 305 to move, drive the clamped cylinder 207 to move and lift the cylinder 207, and then drive the cylinder 212 to convert the pressure of compressed air into mechanical energy to drive the two support plates 211 to move toward each other to close the gap between the two clamping seats 206, thereby preventing the cylinder 207 from falling when it is shaken and intercepting the falling of the cylinder 207.

[0033] During the lifting process, due to the large weight of the cylinder 207 itself, it will generate a large inertia during lifting, and when blown by wind, the lifting device and the tower itself may be shaken. When there is a tendency for the cylinder 207 to shake, the pressing plate 210 will be pressed downward, thereby driving the top block 215 to increase the clamping force on the cylinder 207, further clamping and pressing the upper end of the cylinder 207 to prevent the cylinder 207 from shaking. The greater the tendency of the cylinder 207 to shake, the greater the clamping force on the cylinder 207, thereby improving the stability of the cylinder 207 during lifting.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
