[0026] There are two groups of auxiliary fixing components, which are respectively arranged on the left and right sides of the bottom end of the beam 1. Each group of auxiliary fixing components includes a slide plate 9, a driving component, a limiting component and a pressing component. The slide plate 9 is slidably connected to the bottom end of the beam 1 through the limiting component. The driving component is fixed to the bottom end of the beam 1 and is connected with the slide plate 9 to drive the slide plate 9 to move. The bottom end of the slide plate 9 is fixedly connected with a mounting seat 11 and a mounting seat 2 12. The pressing component is detachably connected with the mounting seat 11 and the mounting seat 2 12. The pressing component is used to press and fix the corresponding end of the top end of the blade body 6.

[0027] In some specific embodiments, such as Figure 1 As shown, in order to facilitate the lifting of the blade body 6, the suspension assembly includes an extension arm 4 and a supporting member 5. Two extension arms 4 are provided, and are respectively fixed on the front and rear sides of the corresponding ends of the beam 1. A plurality of lifting holes are opened at the bottom end of the extension arm 4. The two ends of the supporting member 5 are respectively connected to the corresponding lifting holes on the extension arm 4. By changing the connection between the supporting member 5 and the corresponding lifting holes, the lifting width of the supporting member 5 can be changed. The supporting member 5 is used to lift the corresponding end of the blade body 6.

[0028] In some specific embodiments, such as Figure 4 As shown, in order to facilitate the movement of the slide plate 9, the driving assembly includes an adjusting cylinder 10, the end of the adjusting cylinder 10 is rotatably connected to the bottom end of the beam 1, the driving end of the adjusting cylinder 10 is rotatably connected to the slide plate 9, and the slide plate 9 is slidably connected to the bottom of the beam 1 through a limiting assembly. Starting the adjusting cylinder 10 can drive the slide plate 9 to slide along the direction of the limiting assembly, and the horizontal position of the pressing assembly can be adjusted.

[0030] In actual work, the steel wire ropes 3 on the top of the crossbeam 1 are connected to the lifting equipment, and then the corresponding ends of the blade body 6 are lifted by two supporting members 5, and the adjusting cylinder 10 is started, so that the adjusting cylinder 10 drives the slide plate 9 to slide left and right along the slide rail 7, so as to achieve the purpose of changing the horizontal position of the blade pressing assembly.

[0031] In some specific embodiments, such as Figure 4 As shown, in order to facilitate the rapid disassembly of the pressing assembly, the pressing assembly is rotationally connected to the mounting seat 11 and the mounting seat 2 12 through multiple twisted shafts. The entire pressing assembly can be dismantled by removing the connected twisted shafts, which is convenient for subsequent vertical hanging, thereby avoiding the fixed pressing assembly from getting stuck in the blades when hanging vertically in the prior art.

[0032] When vertical lifting is adopted in the prior art, Figure 3 As shown, the traditional pressing assembly will interfere with the vertical lifting of the blade. The connection method of the pressing assembly is changed to a detachable connection with the mounting seat 11 and the mounting seat 2 12 through a twisted shaft. By removing the twisted shaft, the assembled components of the connecting plate 13, the blade pressure cylinder 14, the pressure rod 15 and the blade pressure plate assembly 16 can be removed as a whole to avoid interference with a single blade during vertical lifting.

[0033] In some specific embodiments, such as Figure 4 As shown, in order to facilitate the blade pressure plate assembly 16 to press the top of the blade body 6, the pressing assembly includes a connecting plate 13, a blade pressure cylinder 14, a pressure rod 15 and a blade pressure plate assembly 16. The connecting plate 13 is a right-angled triangle block. The triangular connecting plate 13 can provide sufficient supporting force.

[0034] After the slide plate 9 drives the pressing assembly to move to the appropriate position on the top of the blade body 6, the blade pressure cylinder 14 is started, and the blade pressure cylinder 14 is extended, so that the blade pressure cylinder 14 and the pressure rod 15 rotate downward along the corresponding direction, so that the blade pressure plate assembly 16 produces a vertical displacement until the blade pressure plate assembly 16 is pressed to the top of the blade body 6, and pressure is applied to the top of the blade body 6 to support the blade body 6. Finally, the blade body 6 is lifted. By changing the horizontal position of the pressing assembly, it can adapt to the lifting of different types of onshore wind turbine blades.

[0035] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0036] In actual work, the steel wire rope 3 on the top of the crossbeam 1 is connected to the lifting equipment, and then the corresponding ends of the blade body 6 are lifted by two supporting members 5, and the adjusting cylinder 10 is started, so that the adjusting cylinder 10 drives the slide plate 9 to slide left and right along the direction of the slide rail 7, so as to achieve the purpose of changing the horizontal position of the blade pressing assembly. After the slide plate 9 drives the pressing assembly to move to the appropriate position on the top of the blade body 6, the blade pressure cylinder 14 is started, and the blade pressure cylinder 14 is extended, so that the blade pressure cylinder 14 and the pressure rod 15 are rotated downward along the corresponding direction, so that the blade pressure plate assembly 16 produces a vertical displacement until the blade pressure plate assembly 16 is pressed to the top of the blade body 6, and pressure is applied to the top of the blade body 6 to support the top of the blade body 6 to prevent it from falling. Finally, the blade body 6 is lifted, and the horizontal position of the pressing assembly is changed to adapt to the lifting of different types of onshore wind turbine blades.

[0037] When vertical lifting is adopted in the prior art, the traditional pressure plate device will interfere with the vertical lifting of the blade. The connection mode of the pressing assembly is changed to a detachable connection with the mounting seat 11 and the mounting seat 2 12 through a twisted shaft. The twisted shaft can be removed, and the assembled components of the connecting plate 13, the blade pressure cylinder 14, the pressure rod 15 and the blade pressure plate assembly 16 can be removed as a whole to avoid interference with a single blade during vertical lifting. When the blade is lifted horizontally, it can be reset.

[0038] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited to them and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
