Embodiment

[0037] The translation method of the present invention will be specifically described below with the translation process of the urea synthesis tower.

[0038] The diameter of the urea synthesis tower that needs to be translated is nearly 4m, the length is more than 40m, and the weight of a single unit is more than 600 tons. Such as figure 1 As shown, the urea synthesis tower 6 is butt welded at 20 meters north of the urea frame, which is completed by the equipment manufacturer. After the equipment completes the assembly and welding work, it is necessary to translate the equipment from the assembly and welding position to the equipment's hoisting position 7, which is completed by hoisting on site.

[0039] The specific methods and steps are:

[0040] First, the road surface is leveled and hardened, and steel plates are laid on the road surface. The thickness of the steel plate 4 is 30 mm, the width is 1500 mm, the length is 8000 mm, and the number is 8 pieces. image 3 As sh...

Abstract

The invention relates to a translation method of large-scale canned equipment, such as a urea synthesis tower, and aims to provide the translation method of the large-scale canned equipment which is convenient to operate, which can be used for preventing the canned equipment from rolling in the translation process. The translation method of the large-scale canned equipment comprises the steps of 1, smoothing and hardening a road surface; 2, preparing two towage steel grillages, then horizontally arranging the canned equipment, after slowly jacking the canned equipment by a hydraulic jack, arraying the two towage steel grillages to be arranged at the front end and the rear end of the canned equipment, pressing the outer circumferential surface of the canned equipment on the upper surfaces of arc-shaped plates of saddle seats, and enabling the rolling moving direction of weight moving devices to be consistent with the length direction of the canned equipment, wherein each towage steel grillage comprises a saddle seat, two steel grillage bodies and four weight moving devices; 3, fixedly connecting a steel wire rope to the saddle seats, and connecting the other end of the steel wire rope to a winch; 4, starting the winch, and moving the canned equipment to a hoisting position.

Description

technical field [0001] The invention relates to a method for moving large-scale equipment as a whole, in particular to a translation method for cylindrical tank-shaped equipment such as a large-scale urea synthesis tower. Background technique [0002] The urea synthesis tower is one of the key equipment of the urea plant, and it is the main equipment for the reaction of carbon dioxide and liquid ammonia to synthesize urea under high temperature and high pressure. When the urea synthesis tower is transported from the manufacturer to the hoisting site, it must first be towed and then unloaded at the unloading position on the construction site. Due to site constraints, the synthesis tower needs to be moved for a certain distance from the unloading position to the hoisting position. The large urea synthesis tower has a diameter of about four meters, a height of about forty meters, and a weight of nearly 600 tons. The movement of such extra-heavy and extra-large equipment must T...
