Aerial work platform at cantilever arm of large-span viaduct and operation method
According to the aerial work platform at the cantilever arm of the large-span elevated bridge and the operation method, two parallel I-shaped steel guide rails are arranged on the bridge, a walking mechanism between the two I-shaped steel guide rails walks in the length direction of the bridge, and when encountering a capping beam stop block in the walking process, the capping beam stop block is stopped; a driving device drives the suspension construction platform to move upwards and outwards through a transmission mechanism, specifically, a first connecting shaft and a first guide groove are formed in a connecting steel plate, a second guide groove and a second connecting shaft are formed in a guide frame, when the first connecting shaft is located on the leftmost side of the second guide groove and the second connecting shaft is located on the topmost side of the first guide groove, the connecting steel plate is in a vertical state, and the output end of the driving device is not stressed; when the first connecting shaft moves to the rightmost side from the leftmost side of the second guide groove and the second connecting shaft moves to the bottommost side from the topmost side of the first guide groove, the connecting steel plate rotates outwards and moves upwards, the overall gravity center of the balancing weight and the hanging construction platform moves rightwards, and meanwhile the electric winding drum is matched to automatically tighten the traction rope to keep the traction rope in a tensioned state.
本发明公开一种大跨高架桥梁挑臂处高空作业平台及操作方法，通过在桥梁上设置俩并列的工字钢导轨，通过两工字钢导轨之间的行走机构沿桥梁长度方向行走，在行走过程中遇到盖梁挡块时，通过驱动装置经传动机构带动悬挂施工平台上行并外移，具体经连接钢板上连接轴一和导槽一、导向架上导槽二和连接轴二，连接轴一位于导槽二最左侧、连接轴二位于导槽一最顶侧时连接钢板处于竖直状态，驱动装置输出端不受力；连接轴一由导槽二最左侧移至最右侧、连接轴二由导槽一最顶侧移至最底侧时，连接钢板发生外旋并上行状态，配重块和悬挂施工平台整体重心右移，同时配合电动卷筒会自动收紧牵引绳保持牵引绳张紧状态。
