Load transfer device for large blocks

Abstract

The invention relates to a large-scale assembling block load transfer device, which comprises a jacking framework, a plurality of jacks and a base, wherein the jacks are respectively arranged at a plurality of end point parts under the jacking framework, the base is arranged under the jacks, a pad plate and a plurality of steel tubes are arranged above the middle of the base, the steel tubes are connected together to form a dismountable integral steel tube, the jacking framework is inserted into inserting pin holes formed in the steel tube through inserting pins, and the jacking framework and the steel tube are connected together. The large-scale assembling block load transfer device has the advantages that the integral jacking of large-scale assembling blocks can be completed, the weight load transfer of the assembling block is realized, in addition, the effect of transferring the weight load of the assembling block to a boat loading framework can be achieved, meanwhile, the jacks are connected together through the framework, and the integral stability is improved, so the assembling block transferring process is stable and safe.

Description

technical field [0001] The invention relates to a load transfer device, in particular to a load transfer device suitable for a large block on the upper part of a large ocean platform. It belongs to the field of marine engineering construction. Background technique [0002] In order to reduce the risk and cost of offshore hoisting operations, more and more large modules are installed by float-over method. As for the modules installed by the float-over method, generally, a loading frame needs to be provided at the bottom of the barge to meet the height adjustment requirements of the barge during float-over installation in sea areas with harsh sea conditions. [0003] At present, the advanced block construction method is modular construction, that is: the block and the shipping frame are constructed separately. After the construction is completed, the block is lifted to a certain height, and the shipping frame is moved to the lower end of the block. Then, Then lower the block...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned blocks are lifted and lowered for load transfer, the jack method is generally used. However, the weight and load transfer of the blocks cannot be completed by only using the jack. The reason is that due to the limited travel of the jack, its limited travel cannot meet the The blocks are lifted to a height of tens of meters, so it cannot meet the load transfer requirements of large blocks; and because a single jack is a single-column structure, the stability of multiple jacks is relatively poor when coordinated operations
