Abstract
The invention discloses a balance crane used for hoisting box girders of a steel bridge. The balance crane can accommodate different weights and special structures of box girders. The technical scheme includes that through combination of two balance crane parts and lifting lugs on the balance crane, hoisting stability is greatly improved, and the balance crane is applicable to various hoisting facilities such as big floating cranes and portal cranes; in different production and operation areas, the hoisting advantages can be used maximally, and problems of limited model selection of the balance crane and unbalance loading are avoided. In addition, lifting lugs in different size can be selected according to different specifications of box girders of the steel bridge, slings are reasonably distributed, and therefore different tons of box girders can be hoisted.
Description
Technical field
The present invention relates to large-scale steel structure lifting field, particularly for the balance hanging beam of lifting steel bridge box beam.
Background technology
In hoisting process, in order to keep being hung the balance of component, reasonable distribution, balance the load of each suspension centre, reduce the unbalance loading that crane bears, select or to make suitable balance hanging beam most important. For Scotland FOX steel bridge project that Shanghai Zhenhua heavy industry is undertaken the construction of, this steel bridge typical case's section box girder length is about 16.2m, width is about 30.3m, deck-molding is about 4.5m, gross weight is about 200T, special section box girder length has 11.45m, 12.15m, 17.9m, 19.9m etc., single box beam not to weigh about as 140T��390T not etc. Owing to box beam dimensions, weight differ, if adopting traditional single balance hanging beam, it is impossible to meet lifting requirements, the selection of crane be there has also been restriction simultaneously; If the combination of single hanging beam used simply, lifting stability can be reduced, increasing potential safety hazard, being greatly increased construction cost.
Summary of the invention
The brief overview of one or more aspect given below is to provide the basic comprehension to these aspects. This summarizes the extensive overview of the not all aspect contemplated, and is both not intended to identify the key or decisive key element also non-scope attempting to define any or all aspect of all aspects. Its some concepts being uniquely intended to provide in simplified form one or more aspect think the sequence of more detailed description given later.
It is an object of the invention to solve the problems referred to above, it is provided that a kind of balance hanging beam for lifting steel bridge box beam, the weight being suitable for each box beam of steel bridge does not wait and box beam special structure form.
The technical scheme is that and present invention is disclosed a kind of balance hanging beam for lifting steel bridge box beam, described balance hanging beam is made up of two balance hanging beam single-pieces, is wherein welded to connect between two balance hanging beam single-pieces.
One embodiment of the balance hanging beam for lifting steel bridge box beam according to the present invention, is welded by four stay tubes and gusset plate between described two balance hanging beam single-pieces.
One embodiment of the balance hanging beam for lifting steel bridge box beam according to the present invention, described four stay tubes are square tubes.
One embodiment of the balance hanging beam for lifting steel bridge box beam according to the present invention, in described four stay tubes two are perpendicular to the direction of described balance hanging beam single-piece and place, all the other two intersections in described four stay tubes are placed, and weld each through described gusset plate on the cross point of two stay tubes that intersection is placed and with the joining place of described balance hanging beam.
One embodiment of the balance hanging beam for lifting steel bridge box beam according to the present invention, the top and bottom of described two balance hanging beam single-pieces are equipped with at least one hanger.
One embodiment of the balance hanging beam for lifting steel bridge box beam according to the present invention, the size of described hanger is depending on rigging size.
The present invention contrasts prior art following beneficial effect: the present invention is by the mode of the combination of double joint balance hanging beam single-piece and the hanger on balance hanging beam, substantially increase lifting stability, it is applicable to the various hanging device such as large-scale floating crane, gantry crane, in different production operation regions, all can play maximum lifting advantage, avoid the problem such as hanging beam type selecting, equipment unbalance loading simultaneously. And the different size according to steel bridge box beam selects different hanger sizes, reasonable Arrangement rigging, it is achieved the box beam of the different tonnage of lifting.

Detailed description of the invention
After reading the detailed description that embodiment of the disclosure in conjunction with the following drawings, it is possible to be more fully understood that features described above and the advantage of the present invention. In the accompanying drawings, each assembly is not necessarily drawn to scale, and the assembly with similar correlation properties or feature is likely to be of same or like accompanying drawing labelling.
Fig. 1 illustrates the overall structure of the preferred embodiment of the balance hanging beam for lifting steel bridge box beam of the present invention, and Fig. 2 illustrates its top view, and Fig. 3 illustrates its hanger scattergram. Referring to Fig. 1 to Fig. 3, the balance hanging beam of the present embodiment is made up of two balance hanging beam single-pieces 11 and 12, is wherein welded to connect between two balance hanging beam single-pieces 11 and 12. Specifically, it is welded by four stay tubes 21��24 and gusset plate 31��35 between these two balance hanging beam single-pieces 11 and 12.
These four stay tubes 21��24 are square tubes, and two 21,22 directions being perpendicular to balance hanging beam single-piece therein are placed, and two other root 23,24 intersects to be placed. The joining place of the cross point of stay tube 23,24 and itself placed and balance hanging beam single-piece of intersecting is to be welded by gusset plate 31��35. Lifting stability can be improved, it is adaptable to the various hanging device such as large-scale floating crane, gantry crane, in different production operation regions, all can play maximum lifting advantage, avoid the problem such as hanging beam type selecting, equipment unbalance loading simultaneously.
Additionally, the top and bottom of two balance hanging beam single-pieces 11,12 are equipped with at least one hanger 4, a grade size of opening for these hangers 4 all differs, and is depending on rigging size, is so conducive to reasonable Arrangement rigging, it is achieved the different tonnage box beam of lifting.
Fig. 4 to Fig. 6 illustrates the use procedure that balance hanging beam lifts. As shown in Figures 4 to 6, the dimensions of steel bridge box beam 6 according to required lifting, weight select suitable shackle 8, wire line thimble 71��73, according to steel bridge box beam dimensions, weight, balance hanging beam 5 selects suitable hanger, arrange shackle 8, wire line thimble 71��73.
