Description

TECHNICAL FIELD

[0001] The utility model relates to a rail-mounted crane trackside power supply system and belongs to the technical field of transformers. BACKGROUND

[0002] An automated container terminal yard is usually vertically arranged, that is, the stacking direction of containers in the yard is perpendicular to the wharf wall. The yard is managed in a fully enclosed manner. As a key device for loading and unloading operations in the yard, the rail-mounted crane is responsible for interactive operations with horizontal transport devices at both the sea and land sides of the yard and is also responsible for the turning over of containers in the yard. The current automated rail-mounted crane usually adopts a traditional power supply mode of a high-voltage cable reel.

[0003] A Chinese utility model patent with the application number CN202122764300.5 discloses a gantry crane track sliding contact power supply mechanism, which comprises a cross beam horizontally arranged on a bracket and a support seat arranged on the cross beam. The support seat moves linearly along the cross beam. The mechanism further comprises a sliding contact power supply mechanism arranged on the cross beam. The sliding contact power supply mechanism comprises a power supply sliding contact belt, a cable, a sliding block, a carbon brush, and an elastic compression assembly. The inner side of the cross beam is provided with a primary long groove, and the primary long groove is provided with a secondary long groove. The power supply sliding contact belt is arranged in the secondary long groove. The drive shaft is a hollow shaft. The sliding block is installed at the end of the drive shaft. The elastic compression assembly is installed in the sliding block. The carbon brush is installed at the end of the elastic compression assembly. In this way, a relatively long cable does not need to be arranged along the cross beam to supply power to the stepping motor and the crane. The power supply is achieved through the sliding contact between the power supply sliding contact belt and the carbon brush. However, the structure is complex, the installation is cumbersome, and a large space is occupied. SUMMARY
