A kind of container hoisting method

Abstract

The invention discloses a container lifting method. Double hoisting bridge cranes are used for synchronously lifting a first container and a second container from two container trucks; then, the first container and the second container are synchronously loaded on one ship; a third container and a fourth container are synchronously lifted from the ship; and finally, the third container and the fourth container are separatelyloaded on the two container trucks. The container lifting method fully uses the loading and unloading advantages of the double hoisting bridge cranes to reduce such ineffective operation links as returning with empty container trucks and empty lifting toolsof the bridge cranes. According to the container lifting method,a computer is used for calculating the operation sequences of the bridge cranes in each ship position, a container truck guide system is used for renewedly planning lanes of a wharf and on-off gear rules of the container trucks, the problem that the lanes divided by a single hoisting crane and the on-off gear rules of the container trucks cannot satisfy the double-crane operation demands is effectively solved, the transfer time of the bridge cranes is shortened, and the formulatingcomplexity of the operation sequences of the bridge cranesis reduced.

Description

Technical field: [0001] The invention relates to the field of transportation, in particular to container hoisting technology at a wharf, in particular to a container hoisting method. Background technique: [0002] Double forty-foot double-lift bridge cranes are widely used in container ports. In the prior art, the loading operation and the unloading operation must be carried out separately. Taking the loading operation as an example, after the truck enters the wharf, the bridge crane spreader lowers and lifts two containers, and then loads the container into the designated position on the ship. At this time, the truck will return empty, and the bridge crane after unloading The spreader will also return to its original position empty. In this way of operation, every loading and unloading has an action of returning empty trucks and bridge crane empty spreaders, which not only reduces operating efficiency, but also greatly increases the energy consumption of the port.

Problems solved by technology

[0003] The object of the present invention is to provide a container hoisting method. The container hoisting method described in the prior art will solve the problem of lower operating efficiency due to the return of the truck and the spreader with no load during the operation of the double-forty-foot double-lift bridge crane in the prior art. technical issues
