A special hanger for container ship hanging box test and container stacking test and its use method

Abstract

The invention relates to a hanging bracket special for container hanging experiments and container stacking experiments of a container ship. The hanging bracket comprises a hanging bracket frame structure, hoisting pads and container corner fitting connecting devices. The hoisting pads are located at the upper ends of the hanging bracket frame structure. The container corner fitting connecting devices used for being connected with the upper corners of containers are located at the lower ends of the hanging bracket frame structure. The positions of the container corner fitting connecting devices correspond to the positions of corner fittings of the containers in a one-to-one correspondence mode. By adoption of a use method of the hanging bracket, two rows of 40ft containers on one layer or four 20ft containers in two rows and on one layer can be simultaneously hoisted. By adoption of the hanging bracket and the use method, the experimental time of the container hanging experiments and the container stacking experiments of the container ship can be shortened by at least one half, the crane resources in a shipyard can be saved, the speed of the container hanging experiments and the container stacking experiments of the shipyard can be greatly increased, accordingly the dock period and the wharf period can be shortened, and great practical value is achieved. Meanwhile, the hanging bracket for the container hanging experiments and the container stacking experiments further has the advantages of being easy to operate, convenient to use, easy to manufacture and capable of being recycled in a long time.

Description

technical field [0001] The invention relates to the field of container loading and unloading equipment, and more specifically relates to a special hanger for container ship hanging box test and stacking box test. Background technique [0002] For container ships, during the construction process, it is necessary to do the gondola test of all the tanks in the cabin or on the main deck of the hatch cover, and as a project submitted to the shipowner, the gondola test is to determine the safety of the cabin. Whether the levelness of the adjustment plate and the levelness of the main deck box feet of the hatch cover are within the required range, if the levelness is not good, the number of stacked layers will be affected during the operation of the ship; and the stacking test is usually a lashing test. It is carried out at the same time, and the lashing test can only be carried out when the containers are stacked to a certain height. The container stacking test of each container s...

Problems solved by technology

[0003] The hanging box test in the cargo hold is usually carried out in the dock stage, the hanging box test of the main deck hatch cover is usually carried out in the wharf stage, and the stacking box test is basically carried out in the wharf stage. The crane is used, whether it is in the dock stage or the wharf stage to carry out the hanging box and stacking test, it takes up a lot of crane resources. According to statistics, each lifting process takes about 20 to 25 minutes (excluding manual operation time). And the number of boxes that need to be tested on the whole ship is very large, so generally speaking, it will take a lot of time to test the hanging boxes and stacking boxes.

According to statistics, each 9400TEU container ship needs 1.5-2 months for hanging box testing, and 15-20 days for stacking box testing. Such a time is a severe test for the dock cycle and terminal cycle. At the beginning of the test, the crane was basically occupied all the time, which caused great inconvenience to other areas in the shipyard that needed to use the crane, and there would be a phenomenon of waiting for work

[0004] Usually, when the shipyard conducts the hanging box test and stacking box test, only one box or one row of boxes can be lifted each time, that is, each corresponding box position involved must be lifted once. Such an operation will not only waste a lot of time , At the same time, it also caused a great waste of crane resources
