The invention discloses an assembly type frame structure and a crane, the assembly type frame structure comprises a box-shaped frame body, the box-shaped frame body comprises a frame front section, a frame rear section and a frame rear section, the frame front section is provided with a first end and a second end which are oppositely arranged; the frame rear section is provided with a first end and a second end which are oppositely arranged; the frame middle section is located between the second end of the frame front section and the first end of the frame rear section, and the frame front section, the frame middle section and the frame rear section are sequentially arranged and connected end to end; the frame middle section is connected with the frame front section or the frame rear section through a sleeve connecting assembly, the sleeve connecting assembly comprises a tubular shaft and a sleeve, and the sleeve connecting assembly is provided with a T-shaped thread adjusting assembly located at the insertion end of the tubular shaft. The T-shaped thread adjusting assemblies generate axial displacement through mutual rotation to adjust the axial gap between the frame middle section and the frame front section or the frame rear section. The front part and the rear part of the frame are connected into a whole, local torsion of the tail part of the frame is allowed, and the displacement difference between the left side and the right side of the vehicle is buffered.

    本发明公开了一种装配式车架结构及起重机,包括箱型车架本体,箱型车架本体包括:车架前段,所述车架前段具有相对设置的第一端和第二端;车架后段,所述车架后段具有相对设置的第一端和第二端;车架中段,车架中段位于车架前段的第二端和车架后段的第一端之间,车架前段、车架中段和车架后段依次排列且首尾相连;车架中段与车架前段或车架后段通过套筒连接组件相连,套筒连接组件包括管轴和套筒,套筒连接组件上设有位于管轴插入端的T型螺纹调整组件,T型螺纹调整组件通过相互旋转产生轴向位移调整车架中段和车架前段或车架后段的轴向间隙。该结构将车架前后连为一个整体,允许车架尾部发生局部扭转,缓冲车辆左右两侧的位移差。
