The invention discloses a trackless mobile tower crane chassis device which comprises an upper chassis, a lower chassis mounted at the bottom of the upper chassis, and a leveling device for adjusting the levelness of the lower chassis, the upper bottom frame comprises bottom frame sections, half beams and inclined supporting rods used for fixedly connecting the bottom frame sections and the half beams. The lower underframe comprises a supporting cross beam and a connecting beam; the two supporting cross beams and the two connecting beams are connected through connecting pin shafts to form a quadrilateral frame. And the leveling device is fixedly mounted at the bottom of the lower underframe. The upper chassis bears ballasting load, the lower chassis bears axis vehicle load, structural stress is simple, mutual influence of the loads is reduced, structural damage and deformation are not prone to being generated, and walking safety is improved.
本发明公开了一种无轨式移动塔机底架装置,包括上底架,安装在上底架底部的下底架,以及调节下底架水平度的调平装置;所述上底架包括底架节,半梁,以及用于固定连接底架节和半梁的斜撑杆;所述下底架包括支撑横梁和连接梁;两个所述支撑横梁和两个所述连接梁通过连接销轴连接成四边形框架;所述调平装置固定安装在下底架的底部。本发明上底架承载压重载荷,下底架承载轴线车载荷,结构受力简单,降低了载荷相互影响,不易产生结构损伤和变形,提高行走安全性。
