Embodiment Construction

[0031] The technical solutions in the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] combine figure 2 As shown, the method for adjusting the dome of the LNG storage tank to balance the tension of the wire rope of the present invention is adopted, and the specific steps are as follows:

[0033] Step one, install the balance wire rope.

[0034] combine image 3As shown, the outer surface of the dome 3 is provided with a pulley assembly, and the pulley assembly includes a central pulley 91 , two guide rollers 92 and a pulley 93 . Wherein, center pulley 91 is positioned at the center hole position of dome 3, and tackle 93 is positioned at the edge position of dome 3, and two guide rollers 92 are positioned at the middle position of center pulley 91 and tackle 93, and center pulley 91, two guide rollers 92 and tackle 93 are arranged along the same arc on the outer surface of the dome 3 . One end of the balance wire r...

Abstract

The invention belongs to the field of construction of LNG storage tanks, particularly relates to a method for adjusting tension of balance steel wire ropes of an LNG storage tank dome, and aims to solve the problems that when the prior art is adopted to adjust tension of the balance steel wire ropes of the LNG storage tank dome, construction cost is high, construction is difficult and adjustment precision is poor. The novel method for adjusting tension of the balance steel wire ropes of the LNG storage tank dome comprises the step I of mounting the balance steel wire ropes, the step II of establishing a model and confirming the relationship between adjustment force and deformation amount of the balance steel wire ropes, and the step III of adjusting tension of the balance steel wire ropes. When the method is adopted to adjust tension of the balance steel wire ropes of the LNG storage tank dome, construction cost is reduced, tension of all the balance steel wire ropes can be quickly adjusted, all the balance steel wire ropes meet the requirement of tensile force values, and stability and safety of the air jacking process of the dome are guaranteed.

Description

technical field [0001] The invention belongs to the field of LNG storage tank construction, and in particular relates to a method for adjusting the dome of an LNG storage tank to balance the pulling force of a steel wire rope. Background technique [0002] The installation of the dome of the LNG storage tank generally adopts the gas jacking method. In the process of gas lift, in order to ensure that the dome can keep moving upwards horizontally without overturning, a balance device must be provided for the dome. At present, the balanced fixing of the dome is realized by arranging multiple sets of symmetrical balance steel wire ropes along the circumferential direction of the storage tank. combine figure 1 As shown, one end of the balance wire rope 1 is fixedly connected to the edge of the tank bottom 2, and the other end is fixed on the top of the tank wall 5 on the opposite side after passing around the same-side guide roller 41 and the opposite-side guide roller 41 locat...
