The invention belongs to the technical field of pipeline hoisting and particularly relates to a pipe-lowering hoisting self-locking tool for a concrete prefabricated pipeline. The pipe-lowering hoisting self-locking tool comprises a balance structure, transmission structures, a fixed structure and a protection structure and is suitable for pipe-lowering hoisting of the concrete pipeline. For the transmission structures at the two ends, fixed parts are easy to adjust, and angle adjustment is easy to carry out; and the transmission structures can realize self-locking of the lower ends through self weight, and ensure that the lower ends are not opened after being hoisted through stress, so that the labor time during hoisting is shortened, and the risk of manual operation is reduced. Self-locking type hoisting of the pipeline can be achieved, the phenomenon that the pipeline is disengaged is avoided, when the pipeline is lowered, the fixed structure is fixed, the transmission structures are disengaged from the pipeline, and self-lifting is achieved.
本发明属于管道吊装技术领域,特别涉及一种混凝土预制管道下管吊装自锁式工具,本发明包括平衡结构、传动结构、固定结构及保护结构,适用于混凝土管道的下管吊装,本发明两端传动结构容易调整固定部位且进行角度调整,传动结构通过自重能够实现下端的自我锁定,通过受力保证吊起后不打开,减少了吊装时的用工时间,并减小了人工操作的风险。本发明可实现管道自锁式吊装,不会出现管道脱离的现象,管道下放时,固定好固定结构,传动结构脱离管道,实现自提。
