Abstract

The invention discloses a pure electric system for a gantry crane. The system comprises a system controller, an electricity getting device, a battery set, a bidirectional DC/DC converter, an auxiliary DC/AC converter, a charge controller, a bidirectional DC/DC converter controller, a power supply manager connected with the battery set, a power supply balancer and charge equipment connected with a commercial power supply, wherein the charge controller, the bidirectional DC/DC converter controller, the power supply manager and the power supply balancer are connected with the control end of the system controller; the charge end of the battery set can be automatically connected with the charge equipment through the electricity getting device. According to the system disclosed by the invention, the battery set is adopted for supplying power, so that zero pollution and zero emission are realized and the gantry crane is high in flexibility of use.

Description

[technical field] [0001] The invention belongs to the pure electric field and relates to a pure electric power system, in particular to a pure electric power system suitable for a gantry crane. [Background technique] [0002] At present, there are two forms of power sources for gantry container cranes used by wharf enterprises: 1) Adopting the exchange power supply mode of mains power and diesel generator sets, that is, erecting elevated / low-frame trolley lines in the regular yard of the wharf, and in the yard Through the trolley line, the mains power is used for power supply; after leaving the yard, the crane is powered by starting the diesel generator set to generate electricity; 2) The diesel generator set or hybrid system is completely used for power supply. With the depletion of world energy and the increasing global concern for environmental issues, traditional rubber-tyred gantry container cranes with diesel generator sets or hybrid systems are polluting and energy-in...
