Bollard drive for a blocking bollard, and blocking bollard

A bollard drive for a blocking bollard for moving a blocking member between a blocking position and an opening position along a movement direction relative to a base body which is connected to a substrate, the bollard drive comprising:

• a base element which is connected to the base body;
• a drive unit which is arranged on the base element, the drive unit comprising an electric motor, a transmission, and a drive element which is connected to the blocking member, the electric motor and the transmission being configured to electromechanically drive the blocking member along the movement direction relative to the base body via the drive element being driven by the transmission;
• a coupling device comprising a first coupling part and a second coupling part, the coupling device being associated with the transmission and being configured to establish a driving connection in the transmission upon an engagement of the first coupling part with the second coupling part;
• and
• an operating device,
• wherein,
• the first coupling part and the second coupling part are configured to be disengaged via an operation of the operating device so as to interrupt the driving connection and to release a movement of the blocking member relative to the base body.
