Method for quickly installing accessory equipment of large unit in limited space

Abstract

The invention provides a method for quickly installing accessory equipment of a large unit in a limited space. Field investigation is conducted on an air compressor plant, and a live-action BIM is established; three-dimensional hoisting simulation software is utilized for optimizing an auxiliary machine equipment entering and unloading scheme; according to the auxiliary machine equipment unloadingposition, an auxiliary machine equipment sliding in-place route is selected, and a sliding tool platform assembly is manufactured; the auxiliary machine equipment enters a site and is unloaded to a designated position, and T-shaped reinforced wing plates are welded to the two sides of an auxiliary machine equipment base; the direction of the auxiliary machine equipment is adjusted, and the auxiliary machine equipment slides to the position above a foundation; auxiliary machine equipment is jacked from the two sides of the base, the sliding tool platform assembly above the foundation is dismounted, and an auxiliary machine is arranged in place; and final adjustment and acceptance are conducted. The auxiliary machine equipment unloading scheme is optimized through the BIM technology and thethree-dimensional hoisting simulation software, workshop travelling cranes are used for being matched with auxiliary machine unloading in place, meanwhile, the auxiliary machine sliding distance canbe reduced, the auxiliary machine equipment moving speed is increased, and the installation efficiency of auxiliary machine equipment in the limited space is effectively improved.

Description

technical field [0001] The invention belongs to the field of equipment installation, and in particular relates to a quick installation method for auxiliary equipment of a large-scale unit in a confined space. Background technique [0002] Condenser and cooler mainly provide heat exchange and condensate collection for unit operation. It is of great significance to the overall operation stability of the unit. In recent years, with the wide application of large-scale compressor unit equipment, due to the control of process requirements and investment costs, large auxiliary equipment such as condensers and coolers are usually installed in the foundation frame at the bottom of the unit, and the installation is severely restricted. At the same time, the weight of the auxiliary equipment of the large-scale unit is between 45t and 70t, which is much larger than the 32t lifting capacity of the factory building. The traditional method of hoisting equipment in place cannot be used in ...
