Embodiment Construction

[0018] Such as figure 1 Shown, the present invention adopts following steps:

[0019] The first step: fix several slideway beams 1 (two in this embodiment) on the slideway support 2 above the deck layer 5 by spot welding;

[0020] Step 2: Fix several rollers 3 under the large air duct 4 through bolt connection;

[0021] Step 3: Hoist the large air duct 4 equipped with the rollers 3 onto the slideway beam 1, and then move it to the inside of the large module to reverse the large air duct 4.

[0022] The above-mentioned slideway beam 1 is an angle steel, and can be bent according to the installation position of the large-scale air duct 4; The vertical state acts as a boundary guide for the pulley 3.

[0023] The above-mentioned slideway support 2 is angle steel or rib plate; the quantity of slideway support 2 is determined by the length of slideway beam 1 and the weight and length of large air duct 4;

[0024] The above-mentioned roller 3 has the functions of turning and sel...

Abstract

The invention relates to a method for carrying out reverse transportation on a large air pipe in a module. The method adopts the following steps that firstly, a plurality of slideway beams are fixed on slideway supports above a deck layer; secondly, a plurality of rolling wheels are fixed below the large air pipe; and thirdly, the large-scale air pipe equipped with the rolling wheels is hoisted onto the slideway beams and then moved to the inside of the large-scale module to be reversely transported. By the adoption of the method, the air pipe can be quickly laterally mounted to a designated position inside a certain deck layer of the module, and the reverse transportation efficiency is improved; and moreover, the bumping phenomenon of the large air pipe during reverse transportation is not likely to happen.

Description

technical field [0001] The invention relates to air duct reversing, in particular to a method for reversing large air ducts in a module. It belongs to the field of offshore oil engineering construction, hoisting and installation. Background technique [0002] At present, in the manufacturing process of large-scale steel structures, many equipment or air ducts need to be hoisted from the ground and side-mounted to a designated position inside a deck layer of a large-scale module. Due to the large volume of a certain section of the large air duct, the existing method of unloading the large air duct is generally to first hang the air duct with an inverted chain, and then unload it into the module a little bit. This method not only requires a lot of manpower, but also has a slow speed and low efficiency for the transportation of large air ducts; moreover, it is easy to bump the large air ducts during the transportation of large air ducts, which is not conducive to the flange op...
