Embodiment Construction

[0028] Based on the problem that the current method of hydraulically lifting and hoisting a urea synthesis tower occupies a very large construction space, a typical embodiment of the present invention provides a method for hydraulically lifting and hoisting a urea synthesis tower, including the following steps.

[0029] Step 1, a hydraulic lifter 7 is set on the top of the structural frame 6;

[0030] Step 2, setting the track 4 on the ground at the bottom of the structural frame 6, and installing a mobile support platform on the track 4;

[0031] Such as figure 1 , figure 2 As shown, the mobile support platform includes a frame platform 2, the bottom of the frame platform 2 is provided with a pulley 3, and the pulley 3 cooperates with the track 4 laid on the ground at the bottom of the structural frame; one end of the frame platform 2 is fixedly arranged There are gantry cranes 5;

[0032] Step 3, placing the urea synthesis tower 1 horizontally on the frame platform 2 of ...

Abstract

The invention relates to a method for hydraulically lifting and hoisting a urea synthesis tower. A hydraulic lifter is arranged at the top of a structural frame; rails are arranged on the bottom ground of the structural frame, and a movable supporting platform is installed on the rails; the urea synthesis tower is horizontally placed on the frame platform of the movable supporting platform; the movable supporting platform is enabled to translate on the rails until the top of the urea synthesis tower moves to the bottom of the structural frame; the front end of the urea synthesis tower is connected with a steel strand of the hydraulic lifter, and the rear end of the urea synthesis tower is connected with a lifting appliance on a gantry crane through a steel lifting rope; the hydraulic lifter lifts the urea synthesis tower upwards, the gantry crane slips the tail, and meanwhile, the frame platform continues to move forwards, so that the urea synthesis tower is gradually lifted from a horizontal state to a vertical state; and under the action of the hydraulic lifter, the urea synthesis tower is lifted to a mounting position in the structural frame for mounting. According to the invention, the defect that the tail-sliding crane cannot enter a site with a small working space is overcome, and the operation process is safer and more reliable.

Description

technical field [0001] The invention relates to a method for hoisting a reactor, in particular to a method for hydraulically lifting and hoisting a urea synthesis tower. Background technique [0002] With the vigorous development of the national chemical industry, the hoisting technology of large-scale chemical equipment is becoming more and more difficult. The hoisting features mainly include large tonnage, high hoisting height, narrow hoisting space, and tight construction schedule. In the hoisting process of urea production equipment, since the urea synthesis tower is assembled on site by the manufacturer, in order to complete the translation and hoisting of the urea synthesis tower, it is usually necessary to select two or more cranes to coordinate the hoisting operation. [0003] When moving forward for hoisting, one crane is in front and is arranged at the head of the equipment cylinder, and the other crane is behind and is arranged at the lifting lug at the tail of th...
