The working principle is as follows: the device is used for installing the fan blades of the large-scale wind driven generator, and solves the problems that when an adapter for assembling the fan blades of a special vehicle lifting vehicle special for the large-scale wind driven generator is butted with the fan blades, the butt joint efficiency is low, the accuracy is poor, and the damage to the fan blade connecting parts is easy to cause;

the butt joint comprises the following specific steps:

firstly, the lifting car adapter is adjusted to a horizontal angle to be aligned to the first assembly frame 1, the second assembly frame 2 and the third assembly frame 3, the central lines of the three assemblies are backed backwards until the lifting car adapter is close to the first assembly frame 1, the first telescopic support base 112 is pushed to be close to the lifting car adapter through the translation push rod 113 so that the installation disc 121 is attached to the surface of the adapter, in the process, the driving motor 123 rotates the driving disc 122 to enable the matching clamping arm 124 to extend outwards, after the installation disc 121 is attached to the surface of the adapter, a pressure sensor installed through a contact connecting plate 1254 can automatically sense, the height of the first telescopic rack 11 is adjusted to completely clamp the adapter, the driving motor 123 is reversed, and after clamping of the adapter chuck 125 is released, the accurate height of the adapter can be obtained through the telescopic change length of the first telescopic support base 112;
