一种既有铁路隧道病害整治用隧道拱顶钢拱架安装机
摘要：
一种既有铁路隧道病害整治用隧道拱顶钢拱架安装机，属隧道病害整治施工设备技术领域。其构成包括安装台架、安装在安装台架上的钢拱架运行机构以及电气控制部份和液压控制部份，所述的钢拱架运行机构由钢拱架位置校正装置和安装在钢拱架位置校正装置侧边的钢拱架升降及翻转装置构成，其中，钢拱架升降及翻转装置由升降机构、回转机构、翻转机构及固定机构组成，钢拱架位置校正装置由纵移机构、位于纵移机构上方的横移机构、固定于横移机构上的上下移动机构、锁紧机构及上下移动导向机构组成。可使钢拱架跨越承力索的机械化安装，大大降低了劳动强度，提高了工作效率和安全性。
摘要（英）：

The invention discloses a steel arch assembling machine of a tunnel vault for repairing damages of an existing railway tunnel. The steel arch assembling machine comprises an assembling rack, a steel arch operating mechanism which is arranged on the assembling rack, an electrical control part and a hydraulic control part, wherein the steel arch operating mechanism comprises a steel arch position correcting device and a steel arch lifting and turning device which is arranged on the side of the steel arch position correcting device; the steel arch lifting and turning device comprises a lifting mechanism, a swing mechanism, a turning mechanism and a fixing mechanism; and the steel arch position correcting device comprises a longitudinal moving mechanism, a transverse moving mechanism which is arranged above the longitudinal moving mechanism, an up and down moving mechanism which is fixed on the transverse moving mechanism, a locking mechanism and an up and down moving guide mechanism. According to the invention, the steel arch exceeds the mechanical assembling for a carrier cable, so that the labour intensity is greatly reduced, and the working efficiency and safety are improved.
