The invention provides a telescopic crawler crane. The telescopic crawler crane comprises a frame, a crawler frame and a power transmission piece, the track frames are installed on the two sides of the vehicle frame in a telescopic mode in the transverse direction. And the power transmission piece is connected between the frame and the track frame and can be restrained on the outer side of the track frame in the longitudinal direction when the track frame shrinks. According to the telescopic crawler crane, the mode that the power transmission piece is connected with the frame and the crawler frame is adopted, when the crawler crane works, the track gauge of the crawler frame is the maximum, the frame and the crawler frame are completely separated from each other, and the power transmission piece serves as a middle bridge to transmit vertical loads and walking driving force; meanwhile, when the crawler crane carries out transportation, the crawler frame retracts to the minimum track gauge, the power transmission piece can be restrained on the outer side of the crawler frame without being detached, and therefore the requirement that the whole transportation of the frame and the crawler frame meets the road specification requirement can be met.
本发明提供一种伸缩式履带起重机,该伸缩式履带起重机包括车架、履带架和动力传递件。其中,履带架沿横向可伸缩地安装于车架的两侧。动力传递件,连接于车架和履带架之间,并能够在履带架收缩时沿纵向约束于履带架外侧。本发明中的伸缩式履带起重机采用动力传递件连接车架和履带架的方式,当履带起重机工作时,履带架轨距最大,车架与履带架完全脱离接触,由动力传递件作为中间桥梁传递垂直载荷和行走驱动力;同时当履带起重机运输时,履带架缩回到最小轨距,动力传递件不需要拆卸便能约束于履带架外侧,从而能满足车架与履带架整体运输符合道路规范要求。
