Description

Double-trolley drive mechanism for crossing-type double-trolley quay crane

technical field

The invention relates to a through-type double-car quay bridge, in particular to a double-car driving mechanism for a through-type double-car quay bridge, and belongs to the technical field of heavy object lifting.

Background technique

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.

During the unloading process of traditional port containers, the container is lifted by a single lifting trolley on the traditional quay crane, 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. Then place the container on the container truck. After the container is placed, the lifting trolley returns to the top of the container ship for the shore bridge and sea survey to hoist the next container. Traditional quay cranes operate with a single trolley, and the efficiency has not been effectively improved. Despite the adoption of technical measures such as improving equipment operating parameters, increasing lifting weight, and using double spreaders, the loading and unloading efficiency of quay cranes has not been qualitatively improved. With the emergence of ultra-large container ships with a container capacity of 18,000 TEU or even 24,000 TEU, their huge advantages of high capacity, low energy consumption and low emissions have made major shipping companies rush to purchase and put them into operation. The operating efficiency of the equipment puts forward higher requirements, usually requiring a ship-hour efficiency of not less than 300TEU/h, but the existing traditional quay cranes cannot achieve this ship-hour efficiency. Therefore, a high-efficiency quay crane is required to meet the 18000TEU Even the loading and unloading needs of 24,000TEU ultra-large container ships.

In order to improve the loading and unloading effect, a lifting trolley can be added to the traditional quay crane, and the two trolleys can pass through each other when moving along the main girder, and the two trolleys can work together to greatly improve the loading and unloading efficiency. Nor will it increase excessively. The most critical thing is how to arrange the driving mechanisms of the two hoisting trolleys, namely the hoisting mechanism, the traveling mechanism and the wire rope winding system, so that the two trolleys do not interfere with each other during work; at the same time, the outreach of the boom of the quay crane reaches 80 meters , The wire rope of the hoisting mechanism hangs too long. If there is no suitable tow rope system, the hoisting wire ropes of the two trolleys are in a suspended state, and it is very easy to entangle each other and cause an accident.
