Hoisting Technology of Tower Turning Over

Abstract

A hoisting process for turning over a tower, which adopts the following steps: 1: Prefabricate the tower on the pier; 2: Transport the tower to the spraying workshop for spraying; 3: Arrange auxiliary scaffolding and straight ladders on the top deck of the tower; 4: Connect the slings on the gantry crane to the lifting points and poles of the tower; 5: The hooks of the upper trolley and the lower trolley of the gantry crane are lifted at the same time until the tower is in an upright state; 6: Adjust the position of the tower to the position after installation The direction and position are the same; Seven: Install the coupler head of the lower trolley in place, install the tower to the corresponding position of the module, and fix it; Eight: After connecting the safety rope, remove the buckle. The present invention not only solves the problems of erection, angle adjustment and in-place installation of the tower; greatly improves the efficiency of the overall prefabrication of the tower; moreover, it also solves the problem of split prefabrication of the tower, and the problem that all tower accessories cannot be carried and hoisted; During the process, the structural integrity of the tower is improved, which improves the safety during the tower prefabrication process.

Description

technical field [0001] The invention relates to a tower frame, in particular to a hoisting process for turning over a tower on an onshore liquefied natural gas module. It belongs to the field of offshore oil engineering. Background technique [0002] Currently, the onshore large-scale liquefied natural gas large-scale module contains some steel structure tower frames. The traditional tower frame prefabrication method is to divide the tower structure into several small structures, and prefabricate and hoist them separately. Since the tower frame needs to be divided into multiple units for prefabrication, not only is it easy to damage the integrity of the tower structure; moreover, some auxiliary structures in the tower cannot be installed on the tower in advance because of the division. [0003] Usually, because the frame height of this type of tower is tens of meters high and the center of gravity is high, the overall horizontal construction is basically adopted in the pre...

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and provide a hoisting process for turning over a tower, which not only solves the problem of erecting and adjusting the angle of the tower through hoisting after the tower structure is completed using horizontal prefabrication, and finally It greatly improves the efficiency of the overall prefabrication of the tower; moreover, it also solves the problem of split prefabrication of the tower, and the problem that all the accessories of the tower cannot be carried and hoisted; it ensures the structural integrity of the tower during the entire construction process and improves the prefabrication process of the tower. The safety in the medium reduces the workload of the final assembly
