Container gantry crane with bidirectional power supply

Abstract

The invention discloses a container gantry crane with two-way power supply, which comprises a main frame body and drive wheels installed on the left and right sides of the main frame body. In order to realize the two-way power supply of the crane, one The AC power socket is connected to the power circuit inside the crane. In the container gantry crane of the present invention, an AC power socket is respectively installed on the left and right sides of the main frame body to form a two-way independent power supply mode, so that when the crane enters the storage yard, it is not necessary to consider which side of the storage yard the power supply is set on. All can realize the smooth connection of the plug, thereby overcoming the defects of difficult steering and long transition time of the crane, and significantly improving the efficiency of container loading and unloading operations.

Description

technical field [0001] The invention belongs to the technical field of rubber-tyred container gantry cranes, and in particular relates to a container gantry crane capable of realizing bidirectional power supply. Background technique [0002] Rubber-tyred container gantry cranes (commonly known as field bridges) are special machines for large-scale specialized container yards, and play an extremely important role in the container loading and unloading process in ports and terminals. It is not only suitable for the storage yard of the container terminal, but also suitable for the dedicated container storage yard. [0003] The current container gantry cranes are generally powered by diesel AC generators, and digital frequency conversion speed regulation is adopted, which can move in two directions in the container yard. Due to the increase in diesel prices, handling costs have increased. Many container gantry cranes engaged in container operations are changed to one-way AC po...

Problems solved by technology

[0004] Although the use of one-way AC power supply to drive the crane operation reduces the cost of loading and unloading, however, for different storage yards, the laying position of the running track bracket of the sliding contact power supply trolley has been fixed. When the position of the power socket is not on the same side, the power supply trolley cannot be connected to the power socket to provide AC power for the crane

At this time, the crane needs to make a 180-degree turn so that the side where the AC power socket is installed is adjacent to the running track support of the trolley for power supply. Because the crane is bulky and difficult to turn, the required transition time is long. affect work efficiency
