Construction method of cold box interior installation equipment

Abstract

The invention discloses a construction method of cold box interior installation equipment. The construction method of the cold box interior installation equipment comprises the following steps: A, equipment and an outer cylinder of a cold box are formed in a welding mode in advance; B, the outer cylinder is horizontally arranged, a set of conveying tracks are horizontally fixed on the inner wall of the outer cylinder, and the conveying tracks are arranged at the bottom of the inner wall of the outer cylinder; C, a horizontal conveying cart is placed on the conveying track, so that the horizontal conveying cart is guaranteed to move smoothly; D, equipment is horizontally hoisted, a random end of the equipment is placed on the horizontal conveying cart by entering from one end of the outer cylinder; E, the equipment is dragged from the other end of the outer cylinder, and the equipment can be conveyed to a preset position on the horizontal conveying cart; F, connecting supports are installed between the inner wall of the equipment and the outer wall of the equipment one by one till the equipment and the outer cylinder are fixed and guaranteed to be concentric; and F, the conveying track and the horizontal conveying cart are taken out. The construction method of the cold box interior installation equipment has the advantages that not only forming quality of an inner cylinder and the outer cylinder is guaranteed, large-scale refrigerators can be manufactured in a factorization mode, and personnel safety and equipment safety in the construction process are guaranteed.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a construction method for installing equipment inside a cold box. Background technique [0002] The cold box generally includes equipment and an outer cylinder. The equipment and the outer cylinder are welded by a number of annular sections. Due to the high height and large volume of the cold box, the general manufacturing method of the cold box is: the part of the outer cylinder is ring-shaped The sections are vertically superimposed and welded to each other, then part of the annular section of the equipment is vertically superimposed and welded, and then the equipment is vertically placed in the outer cylinder; then part of the annular section of the equipment is welded to the upper end of the partially formed equipment piece by piece, Then part of the annular section of the outer cylinder is welded to the upper end of the partially formed outer cylinder one by one, and the above actio...

AI Technical Summary

Problems solved by technology

This manufacturing method has the following disadvantages: 1. Since the welding of the outer cylinder and the equipment is staggered welding, not all the equipment or the outer cylinder is welded and formed at one time, so the welding of the outer cylinder and the equipment is prone to quality problems; 2. Once there is a After quality problems, because the equipment is inside the outer cylinder, it is difficult to make up for quality defects; 3. Since it is placed vertically and welded section by section, it needs a sufficient height to complete, and the ordinary workshop height obviously cannot meet
