Description

Bottom basket detaching device for ultra-large hanging basket Technical Field The utility model relates to the technical field of bridge construction, in particular to a bottom basket dismantling device for an oversized hanging basket. Background In bridge engineering, a cantilever basket hanging method is adopted for cast-in-situ continuous box girder construction, and is a common method. Usually, after the cantilever cast-in-situ construction is completed, the hanging basket is required to be detached, and the link is often ignored by people. At present, in the process of dismantling the bottom basket, the field construction tool is crude, common construction auxiliary tools are provided with steel wire ropes, finish rolling threaded steel, hanging strips and the like, the requirements of dismantling the common small hanging basket can only be barely met, the bearing requirements can not be met at all when the large hanging basket (30 t bottom basket system) is faced, the problems that the auxiliary tools are easy to brittle fracture, the dismantling and the releasing are asynchronous and the like are caused, and hidden dangers are buried for construction safety. In view of this, the present application has been made. Disclosure of utility model The utility model aims to provide a bottom basket dismantling device for an oversized hanging basket, which is characterized in that a hanging steel strand is connected with a bottom basket system, the end part of the steel strand is connected to a poured box girder, and then the bottom basket is lowered by utilizing the telescopic movement of lifting equipment, so that the safety and synchronism of the bottom basket dismantling can be improved.
