The invention discloses a mobile crane supporting device. The device comprises a bottom plate, a bottom frame, a transverse flat plate, a supporting single body mechanism, a longitudinal flat plate, transverse rotating shaft supporting beams, longitudinal rotating shaft supporting beams and a bottom stress plate. The bottom plate is connected with the lower end of the bottom frame, a bottom framehydraulic cylinder is fixed to the bottom frame, the longitudinal rotating shaft supporting beams are arranged at the front side and the rear side of the bottom frame, a longitudinal motor is arrangedin the middle of the interior of each longitudinal rotating shaft supporting beam, longitudinal rotating shafts are connected to the two ends of each longitudinal motor, longitudinal supporting hydraulic cylinders are arranged at one ends of the longitudinal rotating shafts, and the longitudinal flat plate is connected with the telescopic ends of the longitudinal supporting hydraulic cylinders. The transverse rotating shaft supporting beams are arranged at the left side and the right side of the bottom frame. The supporting device is novel in structural design, the contact area between a crane and the ground is increased, the good supporting effect is achieved, damage to the ground when the crane works is reduced, and the self-balance of the crane in the working process is improved.
本发明公开了一种流动式起重机支撑装置,包括底板、底架、横位平板、支撑单体机构、纵位平板、横位转轴支撑梁、纵位转轴支撑梁和底部受力板,所述底板与底架的下端连接,底架上固定有底架液压缸,所述纵位转轴支撑梁设置在底架的前后两侧,纵位转轴支撑梁的内部中间设置有纵位电机,纵位电机的两端连接有纵位转轴,纵位转轴的一端设置有纵位支撑液压缸,所述纵位平板与纵位支撑液压缸的伸缩端连接,所述横位转轴支撑梁设置在底架的左右两侧;本发明结构设计新颖,加大了起重机与地面的接触面积,除了起到良好的支撑作用外,还减小了起重机工作时对地面的破坏,提高了起重机工作过程中的自身平衡。
