The invention provides a large pipe fitting hoisting device for civil engineering. The hoisting device comprises a transverse plate, the transverse plate is connected with two positioning devices through a transverse moving mechanism, each positioning device comprises a vertical plate, the upper end of each vertical plate is connected with the transverse plate through a transverse moving mechanism, a plurality of grooves which are uniformly distributed in the circumferential direction are formed in each vertical plate by taking a certain point as the circle center, each groove is internally provided with a jacking piece in sliding connection with the groove, and a synchronous pushing mechanism is fixed to each vertical plate and is used for driving the multiple jacking pieces to synchronously move relative to the circle center of the vertical plate to abut against the inner side of a pipe fitting. The two positioning devices extend into the pipe fitting from the two sides of the pipe fitting, and the pipe fitting is jacked in the circumferential direction from the inner side of the pipe fitting through the multiple jacking pieces, so that the transportation stability of the pipe fitting is improved, and meanwhile, the problem that the key service life is shortened due to local position stress concentration when the pipe fitting is hoisted is avoided.
本发明提供一种土木工程用的大型管件吊装装置,包括横板,横板通过横向移动机构连接两个定位装置,每个定位装置均包括竖板,竖板上端通过横向移动机构与横板连接,竖板上以某一点为圆心开设有多个周向均布的凹槽,每个凹槽内设有一与其滑动连接的顶紧件,竖板上固定有同步推进机构,同步推进机构用于带动多个顶紧件相对竖板圆心同步移动顶紧在管件内侧;本发明将两个定位装置从管件的两侧伸入到管件内部,并利用多个顶紧件从管件内侧周向顶紧管件,提高了管件运输的稳定性,同时避免管件在吊装时局部位置应力集中进而造成关键使用寿命降低的问题出现。
