Container loading and unloading shore bridge with lifting type double-layer girder and three trolleys

Abstract

The invention discloses a container loading and unloading shore bridge with a lifting type double-layer girder and three trolleys. The container loading and unloading shore bridge comprises a whole lifting girder and a supporting frame, wherein the whole lifting girder comprises upper bearing beams and lower bearing beams; a hoisting trolley A and a hoisting trolley B are respectively arranged on the upper bearing beams; a transporting trolley is arranged on the lower bearing beams; the two sides of the whole lifting girder are provided with more than 8 girder locking devices; and a lifting mechanism is arranged above the supporting frame and is connected with the whole lifting girder by a hoisting steel rope. Compared with the traditional technology, the container loading and unloading shore bridge disclosed by the invention has the advantages that the whole lifting girder can move up and down on the supporting frame and can be locked at a proper position by the girder locking devices, and the height of the whole lifting girder can be adjusted timely in the loading and unloading process, so that the carrying time of containers is effectively shortened; the two hoisting trolleys and one transporting trolley are adopted for carrying the containers, so that the alignment problem of one trolley for transporting the containers is avoided and the container loading and unloading efficiency is improved.

Description

technical field [0001] The invention relates to a container loading and unloading quay bridge with lifting double-layer girders and three trolleys, which belongs to the field of port container logistics. Background technique [0002] The quay crane is the main loading and unloading tool used in the port, and the quay crane plays a very important role in the container loading and unloading process of the port. Since my country's accession to the World Trade Organization, my country's import and export trade has also continued to increase, which has put forward higher requirements for the throughput of my country's ports. Traditional loading and unloading quayside bridges have been difficult to meet the requirements. Therefore, container The quay bridge is improved.

Problems solved by technology

Since my country's accession to the World Trade Organization, my country's import and export trade has also continued to increase, which has put forward higher requirements for the throughput of my country's ports. Traditional loading and unloading quayside bridges have been difficult to meet the requirements. Therefore, container Improvement of quayside bridge

[0003] During the unloading process of traditional port containers, the container is lifted by the lifting trolley on the quay bridge, and the lifting trolley lifts the container along the track from one end of the quay bridge to the top of the truck at the other end of the quay bridge, and then lifts the container The container is placed on the truck, because the height of the lifting trolley from the ground remains unchanged, while the stacking height of the container on the ship keeps decreasing, most of the containers do not have anti-sway devices, and the spreader is easy to swing due to the influence of the external environment, resulting in It takes a lot of time to dock the spreader on the lifting trolley with the container, which seriously affects the loading and unloading efficiency of the container

At the same time, as the height of the container stack on the ship decreases, the time for the spreader to lower and lift during the lifting of the container is getting longer and longer, which also seriously affects the loading and unloading efficiency of the container.
