Bank crane with three sets of trolleys

Abstract

The invention discloses a bank crane with three sets of trolleys and is applied to a double-layer storage yard. According to the bank crane, a front crossbeam and a rear crossbeam are arranged perpendicular to the bank line direction; a crossbeam rail is arranged on the front crossbeam and the rear crossbeam and extends from the front crossbeam to the rear crossbeam; a portal rail is arranged along a doorframe association crossbeam; a transfer platform is arranged below the doorframe association crossbeam; a front trolley runs along the crossbeam rail; the front trolley loads and unloads containers between a ship and the transfer platform; a rear trolley runs along the crossbeam rail; the rear trolley loads and unloads containers between the upper-layer storage yard and the transfer platform; a portal trolley runs along the portal rail; the portal trolley loads and unloads containers between the ground and the transfer platform. The number and the positions of the trolleys are reasonably set, loading and unloading of the ship and loading and unloading on a same storage yard layer can be synchronously performed through the mode of decomposing the loading and unloading flow by utilizing the transfer platform, and the overall loading and unloading efficiency of the double-layer storage yard is greatly improved.

Description

technical field [0001] The invention relates to the field of container cranes, more specifically, relates to a shore crane with three sets of trolleys. Background technique [0002] With the continuous enlargement of container ship berths and the rapid growth of container throughput, higher requirements are put forward for the fast loading and unloading of container terminals. At the same time, the increasingly scarce land resources will also become a bottleneck for increasing throughput. In order to meet the fast loading and unloading of containers and increase productivity as much as possible on a limited land area, it will become an explorable way to develop container yards into space, such as using a double-layer container yard with upper and lower floors. The double-layer storage yard can double the capacity of the storage yard. [0003] The ensuing problem is that with the emergence of double-deck storage yards with upper and lower floors, existing container handling ...

AI Technical Summary

Problems solved by technology

[0003] The ensuing problem is that with the emergence of double-deck storage yards with upper and lower floors, existing container handling equipment, such as single-trolley quayside cranes and double-trolley quayside cranes, cannot meet the rapid loading and unloading requirements of double-deck storage yards. need

The existing single-trolley quayside cranes and double-trolley quayside cranes are designed for the loading and unloading mode of single-layer storage yards, so their loading and unloading capacity and loading and unloading mode cannot meet the needs of double-layer storage yards
