The invention belongs to the technical field of pump shaft hoisting, and particularly relates to a large pump unit pump shaft hoisting tool which comprises a hoisting cross beam and a bearing plate arranged below the hoisting cross beam, a hoisting hook is fixedly connected to the bottom of the hoisting cross beam, and a connecting block is fixedly connected to the top of the hoisting cross beam. The interior of the connecting block is rotationally connected with a two-way threaded rod with threads on the two sides being opposite in direction. Through the arrangement of the two-way threaded rod, the threaded sleeve, the limiting barrel, the gear, the tooth roller and the bearing plate, the device has good stability in the pump shaft hoisting process, the situation that the pump shaft is prone to large shaking when hoisting is carried out only through a hoisting hook is prevented, and therefore the probability of safety risks can be reduced, and the safety of the pump shaft is improved. And the pump shaft can be protected in the lifting process of the pump shaft, the situation that the pump shaft falls off and directly hits the ground to face people on the ground to threaten life is avoided, the pump shaft is prevented from being directly damaged, and therefore certain property loss is avoided.
本发明属于泵轴吊装领域技术领域,具体涉及一种大型泵组泵轴吊装工具,包括吊装横梁和设置在吊装横梁下方的承载板,吊装横梁的底部固定连接有吊钩,吊装横梁的顶部固定连接有连接块,连接块的内部转动连接有两侧螺纹方向设置为相反的双向螺纹杆;本发明通过双向螺纹杆、螺纹套、限位筒、齿轮、齿辊和承载板的设置,进而此装置在进行泵轴吊运的过程中具备良好的稳定性,防止单靠吊钩进行吊运时泵轴容易产生较大的晃动,从而则会降低存在安全风险的概率,并且在对泵轴进行吊运的过程中可以对泵轴进行防护,避免泵轴发生掉落会直接砸向地面对地面的人群造成生命威胁,且防止泵轴会直接发生损坏,从而避免产生一定的财产损失。
