The invention discloses a rapid lifting device for bridge construction, which comprises a balancing weight with the top connected with a lifting machine through a first steel wire rope; the top of each lifting block is connected with the lifting machine through a second steel wire rope; the two parallel side edges of the lifting block abut against the upper surface and the lower surface of a top plate of the to-be-lifted steel box girder correspondingly, and the middle straight edge of the lifting block abuts against the circumferential edge of the top plate of the to-be-lifted steel box girder. Each telescopic mechanism is used for connecting the corresponding lifting block with the corresponding balancing weight; the side edges of the lower portions of any two adjacent lifting blocks are connected through the connecting mechanisms. The rapid lifting device for bridge construction is simple in structure, the steel box girder can be lifted on site and lifted and transported to a construction point, extra tools and manpower are not needed to place the steel box girder on a platform in advance or move the steel box girder to the construction point from the platform after the steel box girder is lifted in place, and the rapid lifting device has high economic and practical value.
本发明公开了一种桥梁施工快速提升装置,其包括:配重块,其顶部通过第一钢丝绳与起吊机连接;多个提升块,每个提升块的顶部通过第二钢丝绳与起吊机连接;提升块的两个相互平行的侧边分别与待提升钢箱梁的顶板的上表面和下表面抵接,中间的直边与待提升钢箱梁的顶板的周向边缘抵接;多个伸缩机构,每个伸缩机构将提升块与配重块连接;多个连接机构,任意相邻的两个提升块的下部的侧边通过连接机构连接。本发明提供的桥梁施工快速提升装置的结构简单,可以就地吊取钢箱梁,并将钢箱梁提升调运至施工点,无需额外的工具、人力将钢箱梁提前放置于平台或吊装到位后将钢箱梁从平台移至施工点,具有较高的经济实用价值。
