The invention discloses a steel-concrete mixed variable cross-section continuous box girder bridge cantilever casting and cantilever splicing combined crane with a good supporting effect, and relates to the field of cranes, the steel-concrete mixed variable cross-section continuous box girder bridge cantilever casting and cantilever splicing combined crane comprises a supporting frame and a crane main body arranged on the supporting frame, the supporting frame is provided with a supporting rod, the supporting rod can move on the supporting frame, the supporting rod is provided with a fixing assembly, and the fixing assembly can move on the supporting frame. The supporting rod can be fixed to the supporting frame through the fixing assembly, and in the moving process of the supporting rod, the fixing assembly relieves fixing of the supporting rod; a bearing assembly is arranged on the supporting frame. One end of the constructed bridge section is supported through the bridge piers, the other end of the constructed bridge section is supported through the supporting rods, linear deformation and stress damage caused by overlarge stress of the constructed bridge section under the gravity of the constructed bridge section are reduced, stress of the supporting rods is transmitted to the supporting frame through the supporting units, and the bearing capacity of the supporting rods is improved; the supporting rod is locked on the supporting frame through the locking unit, the stability of the supporting rod after being stressed is guaranteed, the supporting rod is not prone to displacement or disengagement from the supporting frame after being stressed, and it is guaranteed that the structure is safe and reliable.

    本发明公开了一种支撑效果好的钢‑混混合变截面连续箱梁桥悬浇悬拼联合吊机,涉及到吊机领域,包括支撑架和设置在支撑架上的吊机主体,支撑架上设置有支撑杆,支撑杆能够在支撑架上移动,支撑杆上设置有固定组件,固定组件能够将支撑杆固定在支撑架上,当支撑杆在移动过程中,固定组件解除对支撑杆的固定;支撑架上设置有承载组件。使已施工完成的桥段一端通过桥墩支撑,另一端通过支撑杆支撑,减轻了已施工完成的桥段在自身重力下受力过大导致的线性变形和应力破坏,支撑单元将支撑杆的受力传递至支撑架上,提高了支撑杆的承载能力,通过锁定单元将支撑杆锁定在支撑架上,保证支撑杆受力后的稳固性,支撑杆不易在受力后位移或者脱落支撑架,保证结构安全可靠。
