Cantilever bridge girder erection machine and use method of advancing-anchoring system of cantilever bridge girder erection machine
The invention discloses a cantilever bridge girder erection machine and a use method of an advancing-anchoring system of the cantilever bridge girder erection machine. The cantilever bridge girder erection machine comprises a supporting truss system and an advancing-anchoring system, the advancing-anchoring system comprises a machine body advancing driving device, and the machine body advancing driving device comprises a weight system; the ballasting system comprises a rear fulcrum middle chord member, a ballasting tension block and a ballasting structure; the ballasting structure comprises a beam transporting trolley, a bridge steel structure section and a balancing weight; the number of the ballasting tension hoists is two, one group of ballasting tension hoists is vertically arranged, and the two ends of one group of ballasting tension hoists are correspondingly connected with the front end of the beam transporting trolley and lifting points arranged on a middle chord member of a supporting truss system respectively; the rest group of ballasting tension hoists are arranged along the bridge direction, two ends of the rest group of ballasting tension hoists are correspondingly connected with the rear end of the beam transporting trolley and hoisting points arranged on a rear fulcrum middle chord member for supporting the truss system respectively, and a ballasting metering mechanism is arranged on the beam transporting trolley. Therefore, the stability and the safety of the cantilever bridge girder erection machine during aerial operation are improved.
本发明公开了一种悬臂架桥机及其前进‑锚固体系的使用方法。悬臂架桥机包括支承桁架体系以及前进‑锚固体系，前进‑锚固体系包括机体行进驱动装置，机体行进驱动装置包括压重体系；压重体系包括后支点中弦杆、压重受拉葫芦以及压重构造；压重构造包括运梁小车、桥梁钢结构节段以及配重块；压重受拉葫芦包括两组，其中一组压重受拉葫芦竖向布置，两端分别与运梁小车的前端以及支承桁架体系的中弦杆上所设置的吊点对应连接；余下的一组压重受拉葫芦沿着顺桥向布置，两端分别与运梁小车的后端以及支承桁架体系的后支点中弦杆上所设置的吊点对应连接，运梁小车上配置一压重计量机构。因此，本发明提高悬臂架桥机在空中作业的稳定性、安全性。
