The auxiliary device for hoisting connection of the large-diameter prefabricated pipeline comprises an outer arc component coaxially arranged behind the prefabricated pipeline, a plurality of U-shaped clamping groove components are arranged on the circumference of the outer arc component, and the outer arc component is located at the tails of the U-shaped clamping groove components; an inner arc component is coaxially arranged between the outer arc component and the prefabricated pipeline, the inner arc component is located in clamping grooves of the U-shaped clamping groove components, and the diameter of the inner arc component is matched with the diameter of the prefabricated pipeline. And a propelling device is arranged between the outer arc component and the inner arc component in the clamping groove of the U-shaped clamping groove component. Hoisting and butt joint of the prefabricated pipeline are separately operated, the three U-shaped clamping groove components on the outer arc component are clamped to the prefabricated pipeline to assist hoisting equipment in hoisting, the inner arc component and the propelling wheel set slide on the outer side fixing rod piece and the inner side fixing rod piece, and therefore precise butt joint of the prefabricated pipeline is pushed, the butt joint precision is high, and installation is convenient.

    本发明公开了一种用于大直径预制管道吊装连接的辅助装置,包括同轴设置于预制管道后方的外圆弧构件,外圆弧构件的圆周上设置有数个U型卡槽构件,外圆弧构件位于U型卡槽构件的尾部;外圆弧构件与预制管道之间同轴设置有内圆弧构件,内圆弧构件位于数个U型卡槽构件的卡槽内,内圆弧构件的直径与预制管道的直径相适配;U型卡槽构件卡槽内的外圆弧构件与内圆弧构件之间设置有推进装置。本发明将预制管道的吊装和对接分开操作,外圆弧构件上的三个U型卡槽构件卡接在预制管道上辅助吊装设备吊装,内圆弧构件和推进轮组在外侧固定杆件和内侧固定杆件上滑动,从而推动预制管道精准对接,对接精度高,安装方便。
