Referring to fig. 1, the method for installing the accessory plate of the steel containment vessel of the invention specifically includes the following steps:

in step S1, a reference line is established. After the installation of the cylinder in the steel containment vessel is completed, the elevation datum line and the azimuth datum line can be directly established on the surface of the cylinder by means of the total station.

In the embodiment, 24 azimuth reference lines are uniformly distributed along the clockwise circumferential direction with 0 ° as a starting point, and are numbered as AZ01, AZ02, AZ03, … …, AZ22, AZ23 and AZ24 in sequence. And 4 elevation reference lines are uniformly distributed from bottom to top along the vertical direction of the barrel, and are numbered as EL01, EL02, EL03 and EL04 in sequence. Similarly, other numbers of azimuth reference lines and elevation reference lines can be set according to the specific situation of the site.

In the embodiment, when establishing the azimuth reference line and the elevation reference line, the total station is used for measuring, reference points located on different reference lines are made, and then corresponding reference lines are formed through connection between the reference points.

Dividing a primary menu into three options of a cylinder one-ring accessory plate, a cylinder two-ring accessory plate and a cylinder three-ring accessory plate according to the structure of the steel containment; the secondary menu is set to 25 options including "a series", "B series", … …, "SP series", and "JE series" according to the series of accessory boards.

At the moment, the position of the accessory plate on the containment vessel is determined firstly, and then the accessory plates in the area are called in series, so that the mounting and fixing operation of the accessory plates is conveniently carried out according to the area.

In other embodiments, the first level menu of the auto-generation system may be set as the accessory board series and the second level menu may be set as the accessory board position. At this time, the series of the accessory boards is firstly determined, and then the accessory boards are called according to the distribution condition of the series of the accessory boards according to the positions, so that the mounting and fixing operations of the accessory boards are conveniently carried out according to the series.

In step S23, a job table is generated.

Referring to fig. 5, after the calling work of the accessory board is completed, the relationship between the accessory board and the reference line is displayed in a window of Microsoft Excel software, and a job form is generated. The job form in the present embodiment includes the serial number of the accessory plate, the design position of the accessory plate, the attachment coordinates of the accessory plate, and the azimuth reference line and the elevation reference line corresponding to attachment of the accessory plate. At this time, the job form is printed and the operator specifies the attachment board mounting position. Similarly, the items in the operation table can be adjusted according to the requirements in the actual operation process, so that the requirements of site construction are met.

In step S3, the accessory board is mounted.

At this time, the attachment position of each accessory plate is determined and the accessory plate is fixed by the ruler and the tape according to the reference line in the work table and the attachment coordinate of the accessory plate.

In step S4, the position of the accessory board is detected. After the installation and the fixation of the accessory plate are finished, the fixed accessory plate is detected by taking the datum line as a reference, so that the accuracy of the installation position of the accessory plate is ensured.

The position of the accessory plate is detected by adopting different datum lines when the accessory plate is installed, so that human errors caused when an operator determines the position of the accessory plate are avoided, and the accuracy of the installation position of the accessory plate is improved.

In the present embodiment, by adjusting and setting Microsoft Excel software in advance, while obtaining the attachment panel mounting coordinates in step S22 according to the principle of proximity, the detection coordinates of the same attachment panel are obtained with the reference line of the second approach and a detection table is generated for detecting the position of the attachment panel.
