Hoisting structure of bridge engineering cast-in-place box girder steel strand tensioning equipment
The invention discloses a bridge engineering cast-in-place box girder steel strand tensioning equipment hoisting structure which comprises two sets of trusses arranged in parallel, a plurality of sets of guide beams arranged in parallel are arranged between the trusses and connected with the trusses, the guide beams located on the two sides are fixed to the trusses, and the guide beams at the other positions can horizontally move on the trusses. A pulling device is arranged between every two adjacent guide beams, and the pulling devices are connected with the corresponding guide beams respectively. The truss is assembled on the box girder plate on the working face, the phenomenon that tensioning cannot be achieved due to the working face factor is eliminated, the electric hoist is adopted for remote control in the process of self-hoisting preparation, hoisting, lifting, sliding and in-place installation of tensioning jack equipment, and the electric hoist is adopted for sliding to the next steel strand after in-place installation tensioning is completed; the tensioning efficiency and the construction enthusiasm are improved; and meanwhile, the casualty accident phenomenon caused by deformation and sinking of the steel pipe or narrow cover beam tensioning working face and falling of tensioning equipment in the traditional scaffold erecting and tensioning process is eliminated.
本发明公开了一种桥梁工程现浇箱梁钢绞线张拉设备吊装结构，包括两组平行设置的桁架，所述桁架之间设置有若干组平行设置的导梁，导梁均与桁架连接，且位于两侧的导梁均与桁架固定，其他位置的导梁均能够在桁架上进行水平移动，相邻导梁之间设置有拉动装置，拉动装置分别与对应的导梁连接。本发明在工作面于箱梁板上组装桁架，消除因工作面因素无法张拉现象，张拉千斤顶设备自起吊准备、吊装、提升、滑移、安装就位过程均采用电动葫芦远程控制，安装就位张拉完成采用电动葫芦滑动至下一束钢绞线，提高张拉效率及施工积极性；同时淘汰传统脚手架搭设张拉过程中钢管变形、下沉现象出现或盖梁张拉工作面狭窄，张拉设备脱落造成伤亡事故现象。
