Dismounting device for coupling of wind turbine

The utility model relates to the technical field of accessory devices, in particular to a dismounting device for a wind turbine coupler, which can be used for quickly dismounting couplings with different specifications and sizes, so that the working efficiency and the effect of dismounting the couplings by workers are improved. Therefore, the practicability of the wind turbine coupling dismounting device is enhanced. Comprising a device body and further comprises two sets of supporting plates, a top plate, a telescopic air cylinder, a connecting plate, two sets of first sliding blocks, a pressing rod, a connecting assembly and a fixing mechanism, the supporting plates are arranged at the left end and the right end of the top of the device body correspondingly, and the tops of the two sets of supporting plates are connected with one end of the bottom of the top plate correspondingly; the bottom output end of the telescopic air cylinder penetrates through the top plate to be connected with the top of the connec
