Pipe-lowering hoisting self-locking tool for concrete prefabricated pipeline

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of pipeline hoisting, and in particular relates to a self-locking tool for hoisting and hoisting the downpipe of a concrete prefabricated pipeline. Background technique [0002] The construction of prefabricated concrete pipe generally adopts crane to hoist in the existing technology, and steel wire rope and hoisting belt are used during hoisting. When the steel wire rope is hoisted, a steel wire rope is generally used to bind it in the middle of the reinforced concrete pipe. Due to the existence of the pipe socket, the mass distribution is not easy to distribute evenly, and the pipe is easy to tilt and easily cause damage to the pipe; When hoisting and unloading the hoisting belt, it is difficult to adjust the angle of the pipeline because the construction of the core is not easy to rotate. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencie...

When the steel wire rope is hoisted, a steel wire rope is generally used to bind it in the middle of the reinforced concrete pipe. Due to the existence of the pipe socket, the mass distribution is not easy to distribute evenly, and the pipe is easy to tilt and easily cause damage to the pipe; When the hoisting belt is hoisted and unloaded, it is difficult to adjust the angle of the pipeline because of the construction of the core.
