The invention discloses a gantry crane supporting leg jacking device and a construction method thereof. The clamping plates are clamped on the outer wall of the second-stage cross beam for fixing, compared with a welding installation mode, the installation mode is simpler, disassembly is convenient for repeated utilization, a traditional cross beam structure is optimized, the thickness and the material of a cross beam structure plate are optimized, the extension rod can be better extended to a proper position, and the installation efficiency is improved. According to the design method, the supporting frame is fixed, the supporting frame fixes the second-stage cross beam, the limiting sleeve rotates on the outer wall of the threaded connecting rod, the limiting sleeve abuts against the inner wall of the supporting leg cross beam, and it is determined that the optimal design has enough bending strength through calculation; and then, the construction technology is optimized and designed, so that in the construction process, the situation that the cross beam is damaged due to insufficient bending strength, and then safety accidents are caused is avoided, the operation time of workers is shortened, and the labor intensity of the workers is relieved.

    本发明公开了一种龙门吊支腿顶升装置及其施工方法;本发明通过夹板夹在二级横梁的外壁上进行固定,相比于焊接安装方式更简单,且便于拆卸进行重复利用,通过传统的横梁结构进行了优化,对于横梁结构板材的厚度和材质进行了优化,延长杆更好的延长到合适的位置,使得支撑架进行固定,使得支撑架对二级横梁进行固定,限位套筒在螺纹连杆的外壁上转动,使得限位套筒顶在支腿横梁的内壁上,通过计算确定本次优化设计拥有足够的抗弯强度,然后对于施工工艺也进行了优化和设计使得在施工的过程中,横梁不会因为抗弯强度不够而导致损坏进而造成安全事故,减少了员工的操作时间,减轻了员工的劳动强度。
