A steering chassis for a tower crane comprises: a chassis platform; steering assemblies, each steering assembly coupled to a bottom of the chassis platform; the steering assembly comprises an assembly main body for supporting the chassis platform; the oil cylinder is fixedly installed in the inner space, and the oil cylinder is communicated with a hydraulic source so that the piston can move between a contraction position and an extension position relative to the oil cylinder; the upper end of the ball head supporting rod is connected to the piston, the lower end of the ball head supporting rod is connected with the ball head seat, the ball head supporting rod is connected with the assembly body in a sliding mode, and the ball head seat is connected to the chassis walking device; the steering and leveling motor is used for enabling the ball head supporting rod and the chassis walking device to rotate, when the piston is located at the contraction position, the assembly body and the ball head supporting rod are kept locked, and the ball head supporting rod cannot rotate, and when the piston is located at the stretching position, the assembly body and the ball head supporting rod are unlocked, and the ball head supporting rod and the chassis walking device can rotate.
用于塔机的转向式底架,包括:底架平台;转向组件,每个转向组件联接至底架平台的底部;和底架行走装置,转向组件包括:支撑底架平台的组件主体;油缸和设置在油缸内的活塞,油缸固定地安装在内部空间中,油缸与液压源连通以使得活塞能够相对于油缸在收缩位置和伸出位置之间运动;球头撑杆和球头座,球头撑杆的上端联接至活塞,球头撑杆的下端与球头座连接,球头撑杆与组件主体可滑动地接合,球头座连接至底架行走装置;转向及调平电机,其用于使球头撑杆和底架行走装置旋转,其中在活塞处于收缩位置时,组件主体与球头撑杆保持锁定并且球头撑杆无法旋转,在活塞处于伸出位置时,组件主体与球头撑杆解除锁定并且球头撑杆和底架行走装置能够旋转。
