Title:
DIRECT CURRENT POWER SUPPLY SYSTEM AND METHOD FOR RAIL MOUNTED GANTRY CRANE
Document Type and Number:
WIPO Patent Application WO/2020/077969
Kind Code:
A1
Abstract:
A direct current power supply system and method for a rail mounted gantry crane. Said system comprises a rail mounted gantry crane (12) running on a rail, a ground direct current power supply device (13), a sliding contact device (14) and a current collector (15); the ground direct current power supply device (13) comprises a transformer (131) and a rectifier (132), and the output thereof is connected to the sliding contact device (14); the current collector (15) is mounted on the rail mounted gantry crane (12); and the current collector (15) contacts the sliding contact device (14) by means of an electric brush, and the direct current power outputted by the ground direct current power supply device (13) is supplied to the rail mounted gantry crane (12) by means of the sliding contact device (14), the electric brush and the current collector (15), so as to realize mobile direct current power supply to the rail mounted gantry crane (12). The direct current power supply system for a rail mounted gantry crane simplifies the power supply structure, improves the power supply safety, and prolongs the service life. Optimization configuration of the working instruction of the rail mounted gantry crane and reuse of feedback energy enable the direct current power supply system for a rail mounted gantry crane to have advantages in energy saving and operating costs.
