摘　　要：原有各个存梁区起重运行均配设起重提梁龙门吊,间隔设置平行轨道,将成品梁从预制台区转至存梁区需要纵、横向两种龙门吊才能完成,造成一次性投入的施工成本高。利用横向轨道连接相邻并列存梁区轨道,增设一条垂直交叉轨道,同时,相邻的并列存梁区共享其中一条基础轨道,实现相邻存梁区共用一组龙门吊进行起重移动运行作业,解决了以往梁场提梁龙门吊只能纵移无法横移的施工难题。该项技术利用变轨龙门吊设备及交叉轨道系统,完成了存梁区起重存放及出梁任务,有效避免特种设备过多投入而带来的成本风险。Due to the installation of lifting gantry cranes and parallel tracks at intervals for the lifting operation of each beam storage area,two types of gantry cranes,longitudinal and transverse,are required to complete the transfer of finished beams from the prefabricated platform area to the beam storage area,resulting in high construction costs for one-time investment.This article uses horizontal tracks to connect adjacent parallel beam storage area tracks,adding a vertical cross track,and sharing one of the basic tracks between adjacent parallel beam storage areas.This enables adjacent beam storage areas to share a set of gantry cranes for lifting and moving operations,solving the construction problem of using gantry cranes for beam lifting in the beam yard in the past that could only move vertically but not horizontally.This technology utilizes a track changing gantry crane equipment and a cross track system to complete the lifting,storage,and unloading tasks in the beam storage area,effectively avoiding the cost risk caused by excessive investment in special equipment.
