A verticality adjustment method for tower equipment

Abstract

The invention relates to a method for adjusting perpendicularity of tower equipment, and belongs to the field of tower equipment installation. The method comprises the following seven steps that a tower body measurement mark point is set, a tower body is in place, and the perpendicularity deviation in X-X and X-Y directions is measured, the actual deviation of the tower body is determined, a finalmeasuring instrument is erected, main and vice sizing block sets are adjusted, and inspecting and positioning treatment are carried out. The perpendicularity deviation of the two directions existingin 90 degrees of the tower body is synthesized through utilizing a vector operation triangle rule, actual deviation direction and an actual deviation value of the perpendicularity of the tower body are determined, the main sizing block set needing to be adjusted at the bottom of the tower body is determined firstly according to the actual deviation direction of the perpendicularity of the tower body, the adjusting height of the main sizing block set is determined according to the actual deviation value, then the surrounding sub sizing block sets are adjusted, and the actual deviation of the perpendicularity of the tower body is adjusted to meet the standard requirement; according to the method for adjusting the perpendicularity of the tower equipment, the perpendicularity of the tower equipment can be more efficiently and accurately adjusted.

Description

technical field [0001] The invention relates to the installation field of tower equipment, in particular to a method for adjusting the verticality of tower equipment. Background technique [0002] Tower equipment is one of the important unit equipment in chemical and petrochemical production. With the rapid development of my country's chemical industry, the installation of tower equipment will always be involved in the construction of most chemical engineering projects. How to make it safer and more Faster and more accurate installation of tower equipment is also a problem that installation companies need to consider in order to improve the competitiveness of the industry; in the process of aligning and adjusting the verticality of tower equipment, theodolite is usually used, which is a kind of basis Measuring instruments designed to measure horizontal and vertical angles based on the principle of angle measurement are generally divided into two types: optical theodolite and e...

[0003] The biggest problem with this traditional adjustment method is that if you first adjust the shim group near the X-X direction, it will inevitably affect the measurement deviation value of the verticality in the Y-Y direction. , it is necessary to adjust the theodolite multiple times to continuously update the deviation data, which will consume a lot of time and the installation efficiency is very low; a Chinese Fangming patent with the announcement number CN104420694B discloses a general installation method for benzene hydrogenation engineering tower equipment, wherein The steps to adjust the verticality of the tower are to provide two theodolites and set them up at 90 degrees crosswise. By detecting the deviation of the upper and lower axes of the tower body, adjust the thickness of the base plate, and tighten the anchor bolts of the equipment to achieve the verticality of the equipment. However, this is still similar to the traditional method, and a more effective adjustment method is not described in detail. After a preliminary understanding of the prior art, no tower verticality adjustment method similar to the present invention has been found.
