The invention discloses a variable wheelbase structure and a wheeled crane with the same. The variable wheelbase structure comprises a frame, a suspension mounting seat and a wheelbase change driver, one end of the wheelbase change driver is fixed to the frame, the other end of the wheelbase change driver is fixed to the suspension mounting seat, the suspension mounting seat comprises two supporting frames and a connecting plate connected with the supporting frames, and each supporting frame is connected with a sliding block and provided with a locking mechanism. Two sliding ways are fixed to the lower portion of the vehicle frame and attached to the two supporting frames respectively, so that the suspension mounting base and the sliding block can slide along the sliding ways, and the locking mechanism is used for connecting the sliding ways and the supporting frames and limiting the suspension mounting base and the vehicle frame after the wheelbase is adjusted to the preset position. The wheel base variable device is simple in structure, high in bearing capacity and suitable for heavy vehicles and particularly suitable for wheel base variable technical schemes of wheel cranes, and therefore the problem of axle load overload under the heavy load transition working condition of the wheel cranes is solved.

    本发明公开了一种可变轴距结构,以及具有该结构的轮式起重机。可变轴距结构包括车架、悬架安装座、轴距变化驱动器,所述轴距变化驱动器一端固定在车架上,另一端固定在悬架安装座上,所述悬架安装座包括两个支撑架和连接支撑架的连接板,每个支撑架均连接滑块,并安装有锁止机构;所述车架下方固定有两个滑道,两个滑道分别与两个支撑架贴合,使悬架安装座和滑块能够沿滑道滑动,所述锁止机构用于轴距调整到预定位置后,连接滑道和支撑架,对悬架安装座和车架限位。本发明结构简单、承载能力强,适用于重型车辆,特别是轮式起重机的变轴距技术方案,从而解决轮式起重机重载转场工况下的轴荷超载问题。
