Abstract

The invention discloses a urea synthesizing tower hoisting construction method, and belongs to the technical filed of large-scale equipment disassembly and assembly construction. The construction method comprises the steps of transversely pushing a urea synthesizing tower to an assigned position in a concrete frame; putting up a lifting platform at the top of the concrete frame, installing two hoisting beams, and installing two hydraulic lifters above two main beams; making the two hydraulic lifters connected with the urea synthesizing tower below through steel strands separately; making the two hydraulic lifters conduct synchronous lifting work, and integrally lifting the urea synthesizing tower; meanwhile, making a 300t caterpillar crane conduct rotation work, transversely moving the synthesizing tower forwards, and hoisting the urea synthesizing tower to a vertical state under the coordination of the caterpillar crane; continuing to synchronously hoist the urea synthesizing tower to an installation work height, making the hydraulic lifters stop working, and maintaining an aerial posture of the urea synthesizing tower; uninstalling and dismantling the hydraulic lifters after installation is completed. In the urea synthesizing tower hoisting construction method, the problems that the hoisting running cost is large, the operation procedures are complicated, and the working efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of loading and unloading construction of large equipment, and in particular relates to a hoisting construction method of a urea synthesis tower. Background technique [0002] The urea synthesis tower is the largest equipment in the urea synthesis ammonia chemical project, with a weight of more than 500 tons and a length of more than 20 meters. During the transportation of the urea synthesis tower from the equipment manufacturer to the installation site, the loading and unloading of the urea synthesis tower is generally completed by hoisting by a large crane. Due to the high cost of using large cranes and the long time it takes to assemble the cranes, the site requirements for the crane station are also very strict. Not only must the surrounding obstacles be removed, but the foundation must also be treated and thick steel plates laid. The carrying capacity meets the standard requirements, so the method of hoi...
