The invention provides a combined type suspension double-beam crane which comprises a cart walking track, two main beams arranged on the cart walking track and a trolley mechanism arranged on the main beams, the upper sides of the two main beams are connected through a connecting mechanism, the trolley mechanism comprises four connecting rods, and the connecting rods are connected end to end to form a rectangular frame. Trolley walking wheels are arranged on the upper sides of the two connecting rods parallel to the main beam and walk along the main beam; a lifting mechanism is arranged on the upper sides of the two connecting rods perpendicular to the main beam, stretches across the two connecting rods and is connected with a lifting appliance. The combined type suspension double-beam crane can effectively overcome the defects of a conventional single-beam suspension crane and a double-beam suspension crane, compared with the conventional single-beam suspension crane, the effective lifting height is greatly increased, and compared with the conventional double-beam suspension crane, the crane carriage can cross a track to reach a cantilever of a main beam, so that the working range is expanded.
本发明提供了一种组合式悬挂双梁起重机,包括大车行走轨道、设置于大车行走轨道上两根主梁和设置于所述主梁上的小车机构,两根所述主梁的上侧通过连接机构连接,所述小车机构包括四个连杆,各连杆首尾相连形成矩形框架,与主梁平行的两个连杆上侧设置小车行走轮,小车行走轮沿着主梁行走;与主梁垂直的两个连杆的上侧设置起升机构,起升机构横跨两个连杆,所述起升机构连接有吊具。该组合式悬挂双梁起重机可以有效克服常规单梁悬挂起重机和双梁悬挂起重机的缺陷,相较于常规的单梁悬挂起重机大大提高起升有效高度,相较于常规的双梁悬挂起重机,起重小车又可以越过轨道到达主梁的悬臂,扩大了工作范围。
