Embodiment Construction

[0026] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0027] In the prior art, when loading and unloading large-diameter pipes with flanges, a single hoisting method is generally used, and the hoisting efficiency is low. If multiple pipes are used for hoisting, the pipes are likely to collide during the hoisting process, damage the paint on the surface of the pipes, and easily slip between the pipes, resulting in poor safety.

[0028] The invention provides a multi-pipeline hoisting method for large-diameter pipes with flanges, which includes the following steps:

[0029] Step 1: Install packaging brackets 2 on the flanges at both ends of the pipeline 1, and the packaging brackets 2 are fixedly connected to the outer rin...

Abstract

The invention relates to a multi-pipeline hoisting method of large-caliber pipelines with flanges. The method comprises the steps of 1, respectively mounting packaging supports on the flanges at the two ends of the pipeline, wherein the packaging supports are fixedly connected on the outer ring surfaces of the flanges; 2, stacking the plurality of pipelines together, and sequentially connecting the packaging supports arranged at the two ends of the pipelines together to make the pipelines form an integral structure; and 3, hoisting the integral structure. According to the multi-pipeline hoisting method of the large-caliber pipelines with the flanges, the packaging supports are arranged at the two ends of each large-caliber pipeline with the flanges, the plurality of pipelines are fixedly connected to form the integral structure through the packaging supports, and then the integral structure formed by the plurality of pipelines is hoisted; and with the hoisting method, the plurality ofpipelines cannot slide in the hoisting process and then cannot collide with the surfaces of the pipelines, the pipelines are stacked and hoisted simultaneously, and thus the hoisting efficiency of thepipelines is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline hoisting, and more particularly relates to a multi-pipeline hoisting method for large-diameter pipelines with flanges. Background technique [0002] When loading and unloading large-diameter pipelines with flanges, because of the circular flange structure at both ends, if multiple pipelines are hoisted at the same time, collisions between pipelines are likely to occur and the paint on the surface of the pipelines will be damaged. Flange structure, when multiple pipes are hoisted, the pipes cannot fit together, and the hoisting process is prone to slippage, which is less safe. At present, the single-piece hoisting method is used for large-diameter flanged pipes when loading and unloading trucks (ships). The hoisting efficiency is low. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a multi-pipeline hoisting method for large-diameter flanged...
