Fixing device for use during hoisting of petroleum pipeline

Abstract

The invention discloses a fixing device for use during hoisting of a petroleum pipeline. The fixing device comprises two hoisting rings, wherein the inner diameters of the hoisting rings are matched with the outer diameter of the petroleum pipeline; the hoisting rings are made of rubber; connecting rods are connected between upper and lower ends of the two hoisting rings; the connecting rods havetelescopic rod structures, and are adjustable in lengths; outer walls of upper tops and outer walls of both sides of the hoisting rings are provided with hoisting buckles respectively; connection lines between the hoisting buckles on the tops and the hoisting buckles on both sides construct an equilateral triangle; the hoisting rings are connected with pipeline edge fixtures through fixing ropes;the pipeline edge fixtures are used for clamping end parts of the petroleum pipeline. By adopting the petroleum pipeline hoisting appliance disclosed by the invention, two ends of the pipeline can befixed simultaneously through the two hoisting rings, so that both sides of the pipeline can be kept balanced in order to prevent the pipeline from swinging leftwards and rightwards; the three hoistingbuckles on each hoisting ring are distributed in the form of a regular triangle, so that the stability of the hoisting rings is ensured during hosting of a clamping device, upward and downward swinging is avoided, and the pipeline can be hoisted stably.

Description

technical field [0001] The invention relates to an oil pipeline transportation, in particular to a fixing device for lifting the oil pipeline. Background technique [0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the "blood of industry". There are oil reserves in parts of the upper crust. The main component is a mixture of various alkanes, naphthenes and aromatic hydrocarbons. The oil-forming mechanism of petroleum has two theories of biosedimentary oil and petrochemical oil. The former is more widely accepted. It is believed that oil is formed by organisms in ancient oceans or lakes after a long evolution. It belongs to biosedimentary oil and is non-renewable. It is believed that petroleum is generated from the carbon in the earth's crust itself, has nothing to do with biology, and is renewable. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products, ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing pipeline spreader has poor fixity during the lifting and moving process of the pipeline, the pipeline will swing with the swaying of the sling, the pipeline is difficult to maintain balance, and it may slip out of the sling. , this will easily cause damage to the outer wall of the pipeline during the installation process. The purpose is to provide a
