Description

Technical Field

[0001] The utility model relates to the technical field of engineering project construction, in particular to a pipeline end protection device during the pipeline hoisting process of a municipal pipeline project. Background Art

[0002] In recent years, with the development of my country's economy and society and the improvement of people's living standards, urbanization has developed rapidly, and the construction of municipal drainage projects has become more and more common. In the construction process of municipal drainage projects, cast iron pipes, welded steel pipes, and concrete pipes are mostly used. During the pipe lifting and hoisting process, conventional slings and wire ropes are mostly used as fixing and hoisting tools. Due to the wear between the pipe end and the hoisting rope, the wear is increased due to the weight of the pipe, and there is a certain shear force, which causes the contact position between the pipe end and the hoisting rope to wear faster and more seriously, causing damage to the pipe, and affecting the quality and function of the pipe. At present, the commonly used pipes in municipal engineering are divided into two types: circular and rectangular.

[0003] For example, in the current construction of pipeline projects, when pipes are hoisted, on-site workers ignore or do not know how to protect the hoisted pipes, resulting in direct contact between the lifting ropes and the pipes during hoisting, causing the pipes to be directly deformed or damaged by force. At the very least, the pipes will be abandoned, increasing some construction costs, and at worst, it will affect the overall quality of the pipeline system and the subsequent operation and maintenance costs.

[0004] Therefore, it is necessary to provide a pipe end protection device for the municipal pipeline project during the pipe hoisting process to reduce or avoid the deformation and damage of the pipe during hoisting and installation during the municipal pipeline project construction, affecting the quality of the pipeline network project and reducing the service life of the pipeline network.
