一种钢护筒起吊导向装置及钢护筒起吊方法
摘要：
本发明公开了一种钢护筒起吊导向装置及钢护筒起吊方法，涉及桥梁施工领域，其包括转动装置、支撑装置和固定装置，转动装置包括：转动支撑座，所述转动支撑座包括座体和位于座体顶端的转轴；转动座，所述转动座一端转动连接于所述转轴上，护筒支撑部件，所述护筒支撑部件安装于所述转动座上，且所述护筒支撑部件包括用于支撑钢护筒的第一支撑部件和用于抵持所述钢护筒端部的挡止部件。在钢护筒竖直翻转过程中，转动装置支撑于钢护筒末端并供钢护筒转翻转时作为转动支点，因此，钢护筒在转动过程中不会和地面相互摩擦，从而避免了护筒底口局部变形、损伤。
摘要（英）：

The invention discloses a steel protective barrel lifting guide device and a steel protective barrel lifting method and relates to the field of bridge construction. The steel protective barrel lifting guide device comprises a rotary device, a support device and a fixed device. The rotary device comprises a rotary support seat, a rotary seat and a protective barrel support component. The rotary support seat comprises a seat body and a rotary shaft located at the top end of the seat body. One end of the rotary seat is rotationally connected to the rotary shaft. The protective barrel support component is installed on the rotary seat and comprises a first support component used for supporting a steel protective barrel, and a stop component used for abutting against the end of the steel protective barrel. During vertical overturning of the steel protective barrel, the rotary device supports the tail end of the steel protective barrel and serves as a rotary fulcrum during overturning of the steel protective barrel. Therefore, mutual friction does not occur between the steel protective barrel and the ground during rotation, and thus local deformation and damage of a protective barrel bottom opening are avoided.
