Problems solved by technology

[0002] When installing large industrial tanks, it is generally installed in sections. During the installation process, the cumulative verticality of the installed tanks in each section often produces out-of-tolerance accumulation. It is necessary to cut part of the installation welds and readjust the installation verticality of the tank until it is qualified. The process requires a lot of manpower and material resources, which increases the cost of construction and installation

specific Embodiment approach

[0020] Figure 1-Figure 7 It is a specific embodiment of the present invention. The specific implementation is as follows:

[0021] The first step is to install the first section of the tank body 1, and set a fixed sphere 2 on the center bottom plate of the first section of the tank body 1;

[0022] In the second step, the second section of the tank body 3 is installed on the first section of the tank body 1;

[0023] The third step is to use section steel to make the cross bridge 4. The inner diameter of the cross bridge 4 is consistent with the inner diameter of the installation tank. At the same time, a round hole 5 is opened in the middle of the bridge 4, and a pendant 6 is set, and then the cross bridge 4 is placed in the second section. on the tank body 3, and release the pendant 6 to fall vertically;

[0024] The fourth step is to adjust the position of the second tank body 3 according to the position of the pendant 6 and the fixed sphere 2 on the center bottom plate...

Abstract

The invention discloses a method for aligning the perpendicularity of an installation tank body by using a cross-shaped bridge frame, and belongs to the technical field of tank body installation. Firstly, the cross-shaped bridge frame is processed according to the diameter of the installation tank body, the inner diameter of the bridge frame is consistent with that of the tank body, meanwhile, a hole is formed in the middle of the bridge frame, and a pendant is arranged. After the first section of the tank body is installed, a ball body is fixed to a bottom plate in the center of the tank body. The second section of the tank body is installed on the first section of the tank body, the bridge frame is placed on the top surface of the second section of the tank body, meanwhile, the pendant in the center of the cross-shaped bridge frame is released to vertically fall, and the second section of the tank body is adjusted according to the positions of the pendant and the fixed ball body on acentral bottom plate of the first section of the tank body; and after the second section of the tank body is adjusted to enable the pendant to be aligned and contacted with the fixed ball body on thecentral bottom plate of the first section of the tank body, the second section of tank body is installed and aligned. The method has the advantages that the perpendicularity of the installation tankbody is aligned by repeatedly utilizing the cross-shaped bridge frame and the pendant, accumulated installation errors are reduced, installation reworking treatment is avoided, and the tank body is easier and more accurate to install.

Description

technical field [0001] The invention belongs to the technical field of tank body installation, and in particular provides a method for correcting and installing the verticality of a tank body by using a cross bridge. Background technique [0002] When installing large industrial tanks, it is generally installed in sections. During the installation process, the cumulative verticality of the installed tanks in each section often produces out-of-tolerance accumulation. It is necessary to cut part of the installation welds and readjust the installation verticality of the tank until it is qualified. The process requires a lot of manpower and material resources, which increases the cost of construction and installation. Contents of the invention [0003] The object of the present invention is to provide a method for using a cross bridge to correct the verticality of the installed tank body, repeatedly using the cross bridge and pendants to correct the verticality of the tank bod...
