The invention discloses a control method and a control device for a loading and unloading mechanism of a railway piggyback transport car. The method comprises the following steps of putting through a control circuit of a hydraulic pump motor; starting the hydraulic pump motor to start running; starting a hydraulic pump loading valve in a time-delay manner to enable hydraulic oil to enter a control oil way; opening corresponding electromagnetic valves according to a preset sequence to enable corresponding actuating mechanisms of the loading and unloading mechanism to actuate according to the preset sequence. According to the control method and the control device disclosed by the embodiment of the invention, by adopting a relay control mode and a PLC (programmable logic controller) control mode, the loading and unloading mechanism of the piggyback transport car is controlled, so that the corresponding actuating mechanisms of the loading and unloading mechanism to actuate according to the preset sequence, the goal that automatic control is performed on the loading and unloading mechanism of the piggyback transport car is achieved, and the technical problem that the loading and unloading mechanism of the railway piggyback transport car in the correlation technique cannot automatically work is further solved.
