The invention relates to the technical field of engineering machinery charging equipment, in particular to an engineering machinery charging distribution box and a charging connection device. The engineering machinery charging distribution box comprises a box body, more than two three-phase industrial sockets are installed on the box wall of the outer side of the box body, each three-phase industrial socket is connected with a three-phase charging circuit, and the three-phase charging circuits of the three-phase industrial sockets are connected in series to form a total charging circuit. And a connecting end for connecting a vehicle-mounted charger is led out of the main charging circuit on the other side of the box body. The connecting end of the main charging circuit can be connected with a vehicle-mounted charger, the charging distribution box can be electrically connected with a ground power grid through a special charging wire during charging, so that alternating current charging is realized, and compared with a conventional standard alternating current charging socket, a three-phase industrial socket is adopted, so that the current-carrying capacity is obviously improved, the charging power is obviously increased, and the charging efficiency is improved. In specific use, the number of connected three-phase charging circuits can be selected according to the charging power of the engineering machinery, and the high-power charging requirement of the engineering machinery is met.
