The invention discloses an upside-down construction hydraulic jacking device for a large-diameter assembled tank body, which comprises a fixed support, a hydraulic cylinder is arranged on the fixed support, a vertically telescopic hydraulic rod is arranged in the hydraulic cylinder, a vertically telescopic lower telescopic column is further arranged on the fixed support, and a vertically telescopic upper telescopic column is arranged on the lower telescopic column. A jacking end is arranged at the top of the upper telescopic column, a detachable converter is arranged at the top of the lower telescopic column, and the jacking end or the converter is supported by the top of the hydraulic rod. The hydraulic jacking device has the beneficial effects that under the condition of the same jacking height, only a half of hydraulic stroke is needed by the device, the hydraulic jacking force can be improved through reduction of the hydraulic stroke, and the problem that a pressing rod is unstable is avoided; and under the condition of the same hydraulic stroke, the jacking height is doubled, so that a steel plate of the tank body can be designed into a larger size, the splicing seams of the tank body are reduced, and the sealing performance of the tank body is improved, and therefore, the device is more suitable for the jacking operation of the spliced tank body with large diameter and heavy weight.

    本发明公开了一种大直径拼装罐体的倒装施工液压顶升装置,包括固定支座,固定支座上设有液压缸,液压缸内设有竖向伸缩的液压杆,固定支座上还设有竖向伸缩的下伸缩柱,下伸缩柱上设有竖向伸缩的上伸缩柱,上伸缩柱的顶部设有顶升端,下伸缩柱的顶部设有可拆卸的转换器,液压杆的顶部顶撑顶升端或转换器。本发明的有益效果:相同顶升高度的情况下,该装置只需要一半的液压行程,液压行程的降低有利于提升液压顶升力,并且避免了液压杆出现压杆失稳的问题;相同液压行程情况下,顶升高度提升一倍,使得罐体钢板可以设计更大的尺寸,减少罐身拼缝,提升罐体的密封性,因此该装置更佳适用于大直径、大重量的拼装罐体顶升作业。
