Description

Crossing type vibration-proof high-speed shore bridge

Technical Field

The invention relates to the technical field of container handling equipment at ports and docks, in particular to a crossing type vibration-proof high-speed shore bridge.

Background

The port wharf is a connection part of water and land transportation and is used as a hub of two transportation modes, and the port wharf directly finishes the loading and unloading of a container ship and realizes the water and land transportation of the container. The working efficiency of the port and pier determines the loading and unloading efficiency of the container ship and influences the stop time of the container ship, so that the high efficiency is always an important development direction of the port and pier. At present, in order to save the cost in the transportation process, the container ship is developed in a large scale, and a class 3E container ship with the box loading amount of 24000TEU is already put into use, which puts higher requirements on the working efficiency of a port and a wharf.

The loading and unloading work of most containers in the port and pier is completed by a shore bridge, the shore bridge is large-scale loading and unloading equipment for ship operation, and the loading and unloading efficiency of the shore bridge directly influences the working efficiency of the port and pier. The traditional shore bridge realizes the hoisting, taking and transferring of containers through a shore bridge trolley walking on a shore bridge girder and a shore bridge trolley hanger below the shore bridge trolley, and the working efficiency is low. The crossing type shore bridge is a novel high-efficiency shore bridge, an upper trolley and a lower trolley are arranged, the upper trolley can run in a frame of the lower trolley in a crossing mode, the two trolleys do not influence each other, the loading and unloading efficiency of a container can be greatly improved, and the crossing type shore bridge is the main development direction of the shore bridge in the future.

The lifting speed of bank bridge dolly hoist and the functioning speed of bank bridge dolly along the bank bridge girder also influence the handling efficiency of bank bridge to a certain extent, but in actual operation, the speed of bank bridge dolly and bank bridge dolly hoist can lead to bank bridge dolly and the vibration of bank bridge girder at the excessive speed, and speed is fast more, and the amplitude is big more, seriously influences the operation safety of bank bridge. At present, the ultimate take-off and landing speed of a crane trolley lifting appliance of a shore bridge is 75m/min, and the ultimate moving speed of the crane trolley along a girder of the shore bridge is 240 m/min. In order to further improve the lifting speed of a crane trolley lifting tool and the running speed of a crane trolley, the vibration under the high-speed running condition needs to be effectively controlled, and a vibration avoiding system is developed. The installation vibration-avoiding device is an effective vibration-reducing measure, can control the vibration of the bank crane trolley in the traditional bank crane during high-speed operation, reduces the amplitude, and realizes the further acceleration of the bank crane trolley lifting appliance and the bank crane trolley.

Compared with the traditional shore bridge, the upper trolley in the traversing shore bridge passes through the frame of the lower trolley, and the direct use of the vibration-avoiding method of the traditional shore bridge may cause the mutual interference of the upper trolley and the lower trolley, which affects the structural stability and the operation safety of the traversing shore bridge.
