Dismounting device for roller machine transmission wheel

The utility model relates to a dismounting device for a transmission wheel of a roller bed, which comprises a support used for being supported on a track of the roller bed; the lifting mechanism is movably mounted on the bracket; and the clamping part is used for clamping the transmission wheel, and the clamping part is mounted on the lifting mechanism so as to be driven by the lifting mechanism to be close to or far away from the transmission wheel. According to the technical scheme, the support can be stably clamped on the roller bed rail to support the dismounting device, meanwhile, after the clamping part is matched with the transmission wheel in a clamping mode, the clamping part can be driven by the lifting mechanism to move in the direction away from the transmission wheel so as to separate the transmission wheel from the roller bed rail, dismounting is convenient and labor-saving, and the dismounting efficiency is improved. The maintenance operation efficiency of the roller bed transmission wheel is i
