The invention discloses a double-beam crane for shield construction and an operation method of the double-beam crane. The double-beam crane comprises two T-shaped beam bodies which are installed in parallel, a guide rail vehicle of a transverse translation mechanism is installed in transverse guide rail grooves in the inner sides of the two T-shaped beam bodies, a C-shaped through groove with an opening being downward is longitudinally formed in the position, located below the T-shaped beam bodies, of the lower portion of the guide rail vehicle, longitudinal L-shaped through grooves are symmetrically formed in the positions, located on the guide rail vehicle, of the two sides of the C-shaped through groove, a guide rail frame body telescopic mechanisms are installed in the L-shaped through grooves, a longitudinal translation tractor is arranged in the C-shaped through groove, a lifting mechanism is installed on the longitudinal translation tractor, and a clamping mechanism is fixedly connected to the bottom of the lifting mechanism. According to the double-beam crane, the design requirements are met, meanwhile, the problems that displacement or newly-added installation of pipelines above is permanently blocked cannot happen, the double-beam crane is used according to requirements, the utilization rate of narrow and small space in a tunnel is greatly increased, the problem of inclined pulling and inclined hoisting during hoisting, unloading or component installation is solved, potential safety hazards are eliminated, and safe production is promoted.
本发明公开了一种盾构施工用双梁行吊机及其操作方法,包括平行安装的2条丁字型梁体,2条丁字型梁体内侧的横向导轨槽内安装有横向平移机构的导轨车,导轨车下方位于丁字型梁体下方的位置纵向设有开口向下的C型贯穿槽,在C型贯穿槽两侧位于导轨车上对称设有纵向的L型贯穿槽,L型贯穿槽内安装有导轨架体伸缩机构,C型贯穿槽内设有纵向平移牵引车,纵向平移牵引上安装有提升机构,提升机构底部固定连接有夹持机构,本发明达到满足设计要求的同时又不会永久性阻挡上方管线的移位或新增安装等问题,根据需求使用,大大提升了隧道内狭小空间的利用率,解决了吊装、卸载或构件安装时歪拉斜吊的问题,消除了安全隐患,促进了安全生产。
