Construction device for integrally and quickly dismantling large-span prestressed tied-arch bridge by using double floating cranes
The construction device comprises a base, a lifting seat is arranged on the outer wall of the base, a connecting frame is arranged on the outer wall of the lifting seat, a top beam assembly is arranged on the outer wall of the connecting frame, and a mechanical arm is arranged on the outer wall of the lifting seat. A hoisting and moving assembly is arranged at one end of the mechanical arm; the top beam assembly comprises a telescopic frame arranged on the outer wall of the connecting frame. According to the construction device, through the arrangement of the top beam assembly, in the using process, firstly, a telescopic frame is started and controlled to be used so as to move the positions of clamping bases and move the clamping bases to the positions close to a bridge pier base, a large hydraulic cylinder is started and controlled to be used to open clamping frames, and the clamping bases and the clamping frames are used in cooperation to surround the bridge pier base; the large hydraulic cylinder is controlled to move the position of the clamping frame to clamp a bridge pier base, the small hydraulic cylinder is started and controlled to be used, the abutting block upwards abuts against the bridge part, and bonding between the supports at the two ends and the lower chord is eliminated.
本发明公开了一种双机浮吊整体快速拆除大跨径预应力系杆拱桥施工装置，包括底座，所述底座的外壁设置有升降座，所述升降座的外壁设置有连接架，所述连接架的外壁设置有顶梁组件，所述升降座的外壁设置有机械臂，所述机械臂的一端设置有吊移组件；所述顶梁组件包括设置在连接架外壁的伸缩架；该施工装置，通过顶梁组件的设置，在使用中，首先，启动和控制伸缩架使用，来移动卡座的位置，将其移动至桥梁墩座附近，启动控制使用大液压缸，来打开卡架，通过卡座和卡架配合使用将桥梁墩座包围住，并控制大液压缸使用来移动卡架的位置将桥梁墩座卡住，启动和控制小液压缸使用，通过抵块向上顶桥梁部分，消除两端支座与下弦杆之间的粘结。
