Abstract
The invention discloses a method for assembling three saddles of a large-sized pressure vessel tank body, which comprises the following steps: (1) laying a rectangular steel plate on the flat ground, measuring each position of the steel plate by using a level gauge, and leveling the uneven position to ensure that the whole steel plate is in a horizontal state; (2) placing the saddle at a corresponding mounting position on the steel plate according to the mounting size of the pressure vessel tank body; (3) drawing corresponding points of the waist-shaped holes on each saddle on the steel plate, and welding cylindrical pins matched with the waist-shaped holes on the corresponding points after taking off the saddle, so as to ensure that the cylindrical pins are vertical to the steel plate; (4) sleeving a saddle on the welded cylindrical pin, erecting the pressure vessel tank body on the saddle after confirming that the saddle conforms to the installation position, and welding and connecting the pressure vessel tank body with the saddle; (5) and hoisting the pressure vessel tank body welded with the saddle to separate the saddle from the cylindrical pin on the steel plate, and finishing the assembly of the pressure vessel tank body and the saddle after measuring the installation dimension without errors again.
Description
Technical Field
The invention relates to a method for assembling three saddles of a tank body of a large-sized pressure vessel.
Background
The pressure container is generally a closed device which contains gas or liquid and bears a certain pressure, the material of the pressure container comprises metal and nonmetal, and the pressure container is widely applied to the actual life of people and widely applied to various fields such as petroleum, chemical industry, natural gas and the like. The pressure vessel tank body is inconvenient to mount due to the fact that the pressure vessel tank body is large in size, a saddle is welded at the bottom of the pressure vessel tank body at present, the pressure vessel tank body is fixed through the method that a hole position on the saddle is connected with an upper anchor bolt on the ground, however, due to the fact that the pressure vessel tank body is large in size, the saddle is slightly not aligned with the tank body in welding, the situation that the pressure vessel tank body is not mounted with the anchor bolt can occur, manpower is wasted, and huge economic loss can be caused.
Disclosure of Invention
The invention aims to solve the defects of the prior art and provides a method for assembling three saddles of a tank body of a large-sized pressure vessel.
A method for assembling three saddles of a large-sized pressure vessel tank body comprises the following steps:
(1) laying a rectangular steel plate on the flat ground, measuring each position of the steel plate by using a level gauge, and leveling the uneven position to ensure that the whole steel plate is in a horizontal state;
(2) placing the saddle at a corresponding mounting position on the steel plate according to the mounting size of the pressure vessel tank body;
(3) drawing corresponding points of the waist-shaped holes on each saddle on the steel plate, and welding cylindrical pins matched with the waist-shaped holes on the corresponding points after taking off the saddle, so as to ensure that the cylindrical pins are vertical to the steel plate;
(4) sleeving a saddle on the welded cylindrical pin, erecting the pressure vessel tank body on the saddle after confirming that the saddle conforms to the installation position, and welding and connecting the pressure vessel tank body with the saddle;
(5) and hoisting the pressure vessel tank body welded with the saddle to separate the saddle from the cylindrical pin on the steel plate, and finishing the assembly of the pressure vessel tank body and the saddle after measuring the installation dimension without errors again.
As a further improvement, the number of the saddles at the bottom of the tank body of the pressure vessel is 3, and a plurality of kidney-shaped holes are formed in the two ends of each saddle.
As a further improvement, the rectangular steel plate comprises 3 strip-shaped plates, the strip-shaped plates are connected through channel steel or angle steel in a welded mode, and the positions of the strip-shaped plates correspond to the positions of the saddles one to one.
As a further improvement, the leveling method of the steel plate in the step (1) is to add cushion blocks between the steel plate and the bottom surface in the low-lying position.
Has the advantages that:
the saddle is ingenious in design, the saddle and the pressure vessel tank body can be accurately welded together according to the installation size of the pressure vessel tank body, the complex operation during installation of the pressure vessel tank body is reduced, the labor is saved, and the economic loss caused by installation errors is reduced.
