Multi-degree-of-freedom rotation amplitude changing mechanism of boom type bridge detection vehicle and working method
The invention discloses a multi-degree-of-freedom rotation amplitude changing mechanism of an arm frame type bridge detection vehicle and a working method.The mechanism comprises a lifting arm body, one end of the lifting arm body is hinged to a bridge detection vehicle, the other end of the lifting arm body is hinged to a connecting frame, the telescopic end of a first telescopic component is hinged to the bridge detection vehicle, and the fixed end of the first telescopic component is hinged to the lifting arm body; the fixed end of the second telescopic part is hinged to the lifting arm body, the telescopic end of the second telescopic part is hinged to the connecting frame, and when the first telescopic part moves, the lifting arm body is driven to rotate relative to the bridge detection vehicle; when the second telescopic component moves, the connecting frame is driven to rotate relative to the lifting arm body; a swing oil cylinder is fixed to the connecting frame, a connecting base is fixed to the swing oil cylinder, an operation platform is hinged to the connecting base, a third telescopic component is hinged between the connecting base and the operation platform, and when the third telescopic component moves, the operation platform is driven to rotate relative to the connecting base. By using the mechanism, the cable bent towers and the inhaul cables on the inner side of a pier and above an inhaul cable bridge can be detected and maintained in an all-around mode.
本发明公开了一种臂架式桥梁检测车的多自由度回转变幅机构及工作方法，该机构包括一端铰接在桥梁检测车上的举升臂体，举升臂体的另一端铰接有连接架，第一伸缩部件的伸缩端铰接在桥梁检测车上，固定端铰接在举升臂体上，第二伸缩部件的固定端铰接在举升臂体上，伸缩端铰接在连接架上，第一伸缩部件活动时，驱动举升臂体相对于桥梁检测车转动；第二伸缩部件活动时，驱动连接架相对于举升臂体转动；连接架上固定有摆动油缸，摆动油缸固定有连接座，连接座上铰接有作业平台，在连接座与作业平台之间铰接有第三伸缩部件，第三伸缩部件活动时，驱动作业平台相对于连接座转动。使用该机构，能够对桥墩内侧及拉索桥上方索塔和拉索进行全方位检测维修。
