The invention discloses hoisting equipment for steel box girder bridge construction. The hoisting equipment comprises a lifting hook installed on a crane, the bottom end of the lifting hook is fixedly connected with a hanging ring, the inner wall of the hanging ring is fixedly connected with six ropes, the bottom end of the hanging ring is connected with a limiting mechanism, and the bottom end of each rope is connected with a clamp mechanism; when the steel box girder bridge is placed, the electric hydraulic rod downwards pushes the pressing plate, the pressing plate downwards extrudes the upper end face of the steel box girder bridge, the first hanging plate, the second hanging plate and the pressing plate vertically clamp the steel box girder bridge, and the placing stability of the steel box girder bridge is improved; and when the steel box girder bridge needs to be installed, only the electric push rod needs to be moved outwards, the clamping plate is made to leave the steel box girder bridge, the electric hydraulic rod is pulled upwards, the pressing plate and the clamping plate are made to move to the position above the steel box girder bridge, interference to installation of the steel box girder bridge is avoided, and installation of the steel box girder bridge is facilitated.
本发明公开了一种钢箱梁桥施工用吊装设备,包括安装在吊机上的吊钩,所述吊钩的底端固定连接有挂环,所述挂环的内壁固定连接有六个绳索,所述挂环的底端连接有限位机构,所述绳索的底端连接有夹具机构;电动液压杆将向下推动压板,使压板向下挤压钢箱梁桥的上端面,使第一挂板、第二挂板和压板上下夹紧钢箱梁桥,提高钢箱梁桥的放置稳定性,然后,夹板的L型,会在电动推杆的拉力下,会夹紧钢箱梁桥的两端面,从而进一步提高钢箱梁桥的固定效果,待需要安装时,只需要将电动推杆向外移动,使夹板离开钢箱梁桥,电动液压杆向上拉动,使压板和夹板移动到钢箱梁桥的上方,避免对钢箱梁桥的安装造成干涉,方便了钢箱梁桥的安装。
