The CFRP plate lifting bridge with the supports comprises a main beam, bridge abutments, bridge towers and lifting devices, the two ends of the main beam are supported on the bridge abutments, and the middle of the main beam is not directly supported by the bridge towers; the lifting device is composed of a first winding device, a second winding device, a first roll shaft and a CFRP plate strip, the first winding device and the second winding device are symmetrically installed at the two ends of the main beam relative to the bridge tower, the first roll shaft is installed at the top of the bridge tower, the CFRP plate strip bypasses the first roll shaft located at the top of the bridge tower, and the two ends of the CFRP plate strip are fixed to the first winding device and the second winding device respectively; in the natural state, the two ends of the main beam are supported by the bridge abutments, and the middle of the main beam is supported by the bridge towers through the CFRP plate strips. And in a lifting state, the main beam is supported by the bridge tower through the CFRP plate strip. Lifting is conducted through the winding equipment and the CFRP plate strip traction main beam in the lifting device, the structural design is reasonable, safety is high, and the operation efficiency of urban roads or inland river traffic is improved while the original bridge structural form is kept.

    本发明涉及一种CFRP板带支撑的升降桥梁,包括主梁、桥台、桥塔和升降装置,主梁两端支撑在桥台上,主梁中部不直接由桥塔支撑;升降装置由收卷设备一、收卷设备二、辊轴一和CFRP板带组成,收卷设备一、收卷设备二以桥塔对称安装在主梁的两端,辊轴一安装在桥塔顶部,CFRP板带绕过位于桥塔顶部的辊轴一,两端分别固定于收卷设备一和收卷设备二;自然状态下,主梁两端由桥台支撑,主梁中部由桥塔通过CFRP板带支撑;提升状态下,主梁由桥塔通过CFRP板带支撑。本发明通过升降装置中的收卷设备和CFRP板带牵引主梁进行升降,结构设计合理,安全性高,在保持原有桥梁结构形态的同时,提升城市道路或内河交通的运营效率。
