Problems solved by technology

[0004] The current loading and unloading system generally uses a single lifting trolley of a single-deck quay bridge to carry the container. The journey for the container truck to transfer the container to the yard is long, and the transfer process between the transfer trolley and other equipment is time-consuming.
Moreover, the height of the main traveling girder of the traditional quay crane is fixed. When unloading the ship, as the total height of the container decreases, the lifting height of the spreader increases continuously, and the time required for a lifting cycle of the spreader becomes longer and longer. , so the loading and unloading efficiency of traditional containers is not high, which seriously restricts the throughput of the port

Abstract

The invention discloses a container loading and unloading method and an elevation type double-layer girder shore crane container loading and unloading system. The loading and unloading system comprises a yarn crane, a ferry crane and a shore crane, the yarn crane is connected with the shore crane through the ferry crane, the shore crane comprises a framework a, an integrated elevation girder and a framework b, and the framework b is arranged above the framework a. The integrated elevation girder comprises an upper-portion beam, a lower-portion beam and a girder locking device. The framework b comprises an elevation mechanism and a gantry, and the elevation mechanism is arranged on the gantry. Compared with the prior art, the integrated elevation girder can move up and down on the frameworks; due to the fact that the integrated elevation girder is provided with the girder locking device, the integrated elevation girder can be locked at a proper position through the girder locking device; the height of the integrated elevation girder is changed to adjust the hoisting height of a container, the distance between the integrated elevation girder and the container is kept unchanged, the time for carrying the container is effectively shortened, the efficiency of carrying the container is greatly improved in a large degree, and the handling capacity of a port is improved.

Description

technical field [0001] The invention relates to a container loading and unloading method and a container loading and unloading system used for a lift-type double-layer girder quay bridge, belonging to the field of port machinery. Background technique [0002] Container transportation is the main mode of transportation in modern ports, and the standardization and internationalization of containers have promoted the mechanization and automation of logistics transportation in ports. With my country's entry into the World Trade Organization, the proportion of maritime container cargo transportation is increasing, and the throughput of containers is increasing year after year, which poses new requirements and challenges to the efficiency of port container transshipment. [0003] In the process of container sea transportation and storage in the freight yard, the containers are classified and stacked together, so the container handling system is required to handle the containers wh...
