The invention relates to the technical field of pressure steel pipe vertical shaft construction, in particular to an overturning and lowering device and a mounting method thereof. When the main lifting mechanism lifts one end of the pressure steel pipe through the sling, the overturning and lowering device lowers the other end of the pressure steel pipe through the sling of the auxiliary lifting mechanism, so that the pressure steel pipe can be overturned by taking the first lifting point as a rotating center and lowering the second lifting point; the main truss can adapt to the position relation between the pressure steel pipe and the second lifting point after the pressure steel pipe is overturned, so that the pressure steel pipe can be overturned into a vertical state from a horizontal longitudinal placement state, and the position of the first lifting point can be changed through movement of the main truss; the pressure steel pipe can be longitudinally placed in the upper adit, is transported to the vertical shaft opening through the overturning and lowering device and then is overturned and lowered through the overturning and lowering device, the length of single-time transportation and installation of the pressure steel pipe can be larger, the single-time installation length can be increased in the mode, the installation period is further shortened, and when a super-long vertical shaft is encountered, the installation efficiency is improved. And the construction period can be better guaranteed.

    本发明涉及压力钢管竖井施工技术领域,具体是一种翻转下放装置及其安装方法。翻转下放装置,在主起升机构通过吊索吊住压力钢管一端时,通过副起升机构的吊索下放压力钢管另一端,使得能够以第一吊点为转动中心,下放第二吊点使得压力钢管能够翻转,且翻转过程中,能够适应压力钢管翻转后与第二吊点的位置关系,使得可以从水平纵向放置状态翻转为竖直状态,且能够通过主桁架移动改变第一吊点的位置;压力钢管能够在上平洞纵向放置并通过翻转下放装置运输至竖井洞口后,再利用翻转下放装置进行翻转和下放,压力钢管单次运输安装的长度能够更长,这种方式能够提高单次安装长度,进而缩短安装周期,遇到超长竖井时,施工工期也能更好的保证。
