The invention discloses a loading and unloading device for a civil engineering pipeline. The loading and unloading device for the civil engineering pipeline comprises a hoisting cable, wherein the twoends of the hoisting cable are connected with an auxiliary pressure arm in an arc shape, main clamping arms are attached under the two ends of the auxiliary pressure arm respectively, and the lower ends of the two main clamping arms are attached to the left side and the right side of the lower end of the pipeline respectively; a connecting frame is hinged between the upper ends of the two main clamping arms, a bearing stud penetrates through and is in threaded connection with the center of the connecting frame, the upper end of the bearing stud extends upwards and penetrates through the auxiliary pressing arm, and the parts, located on the upper side and the lower side of the auxiliary pressing arm, of the bearing stud are sleeved with and are in threaded connection with limiting nuts respectively; the lower end of the bearing stud is hinged to a lower pressing block, and the lower pressing block is matched with the lower ends of the two main clamping arms to form a three-point clamping structure on the corresponding cross section of the pipeline. According to the loading and unloading device for the civil engineering pipeline, a coarse pipeline loading and unloading mode in the existing civil engineering is changed, a three-point grasping and lifting mode is adopted to replace a mode of lifting a pipeline with a cable through winding, the pipeline is convenient to directly assemble and join in a pit trench, and the problem that the cable is drawn out from the lower part of the pipeline does not need to be considered.

    本发明公开了一种土木工程管道装卸装置,包括起吊缆绳,起吊缆绳的两端连接有呈弧形的副压臂,副压臂的两端下方分别贴靠有主夹臂,使得两个主夹臂的下端分别贴靠在管道的下端左右两侧;两个主夹臂上端之间铰接有连接架,连接架的中央贯穿并螺纹连接有承载螺柱,承载螺柱的上端向上延伸并穿过副压臂,承载螺柱处于副压臂上下两侧的部分上分别嵌套并螺纹连接有限位螺母;承载螺柱的下端铰接有下压块,下压块配合两个主夹臂下端在管道对应的横截面上形成一个三点夹持结构。本发明改变现有土木工程中粗大的管道装卸方式,采用三点抓夹并吊起的方式取代一根缆绳缠绕管道吊起的方式,方便管道在坑沟内直接装配接合,无需考虑缆绳自管道下方抽出的问题。
