Problems solved by technology

[0002] At present, the installation and laying of oil pipelines requires cranes to lift and transfer the oil pipelines into the trenches, and then workers polish the end faces of the oil pipelines, and then weld them with the installed pipelines in the trenches. The lifting of oil pipelines usually uses load-bearing slings When the pipeline is hoisted, the bearing surface of the bearing sling is usually in the middle of the oil pipeline, and the two ends of the oil pipeline are not loaded, so that the oil pipeline is forced to be squeezed by the bearing sling, resulting in deformation of the oil pipeline;
[0003] And because the installation site of the oil pipeline is usually on the plain, there is no shelter nearby, in the windy weather, the wind will pour into the suspended oil pipeline, when the oil pipeline is lifted and transferred, the oil pipeline is very easy to be damaged. Violent shaking due to the influence of wind will cause the risk of collision with the hoisting equipment, and workers cannot hold the pipe for pipe docking, which greatly affects the construction efficiency;
[0004] And before the oil pipeline is welded, the welding end needs to be polished. Due to the influence of the wind, the grinding debris will splash into the inside of the pipeline, affecting the quality of subsequent oil delivery, and the wind blows the grinding debris, which will sputter hurt workers

Abstract

The invention relates to the field of petroleum pipeline transportation, in particular to a petroleum pipeline installation lifting appliance capable of achieving closed polishing. The technical problem that when a petroleum pipeline is transferred, the petroleum pipeline is forced to be extruded by a bearing lifting belt, and deformation of the petroleum pipeline is caused is solved. According to the technical scheme, the petroleum pipeline installation lifting appliance capable of achieving closed polishing comprises a lifting ring, a fixing column, a first hanging lug, a lifting rope, a second hanging lug, a supporting beam, a third hanging lug, an anti-bending system, a sealed polishing system and the like; and the fixing column is fixedly connected to the bottom of the lifting ring. According to the invention, the effects that the petroleum pipeline is limited, the bottom of the petroleum pipeline is wrapped, and the situation that the petroleum pipeline is forced to be extruded and deformed is avoided are achieved.
