Description

Storage tank flip-chip equipment

Technical Field

The utility model relates to an equipment, especially a storage tank flip-chip equipment for construction.

Background

With the continuous development of the petrochemical industry in China, in recent years, petrochemical devices of petroleum, medium petrochemical industry and medium marine oil are continuously built, expanded, reconstructed, moved and rebuilt, particularly, the petrochemical industry in China is rapidly developed, various petrochemical devices are pulled out, the storage capacity of crude oil, semi-finished products and finished product materials is continuously increased, and large storage tanks are more and more widely applied as storage equipment. Therefore, the construction of installing large storage tanks becomes the key point of petrochemical engineering construction. In view of the short construction period and high investment cost of the large-scale storage tank, the selection of a reasonable construction process and effective construction equipment is a main way for saving the cost.

The method for installing the traditional large storage tank by adopting the partitioned hoisting of the crane comprises the following specific steps:

1) hoisting a storage tank bottom plate by using a crane, laying the bottom plate according to a design scheme, and welding the bottom plate; the welding sequence is as follows: welding the middle auxiliary plate and welding the position of the edge plate of the tank bottom, which is close to the edge by 300 mm;

2) the crane is placed at the middle auxiliary plate position, and the first layer of wall plate of the tank wall is hoisted in a slicing mode;

3) assembling and welding the first layer wall plates of the tank wall, and welding the large-angle seams of the first layer wall plates and the edge plates;

4) welding a shrinkage welding seam of the tank bottom edge plate and the middle auxiliary plate;

5) hoisting other wall plates of each circle by using a crane to complete the installation work of the tank wall;

6) along with the gradual rising of the wall plate, a scaffold is erected outside the tank to carry out welding operation on the wall plate, and a movable trolley (or the scaffold in the tank) is suspended inside the tank to complete the welding of the wall plate in the tank;

7) after the tank wall is installed, cutting the tank wall to open a gate, withdrawing the crane out of the tank through the gate, and then welding the position of the gate again;

8) hoisting a tank top plate by using a crane, and assembling and welding;

9) and integrally hoisting the tank top by using a crane to finish the installation of the tank top.

This method has many drawbacks, as follows:

1) the method mainly uses crane hoisting, the using amount of the cranes is large, and the machine shift cost of the cranes is increased;

2) the method uses the crane to hoist the wallboard, increases the assembly difficulty of the wallboard, and ensures that the assembly precision is not easy to control;

3) the method needs to set up a large number of scaffolds, so that the labor consumption and the use of scaffold materials are increased;

4) the method has large high-altitude operation amount, and increases the construction difficulty and danger;

5) the method adopts the movable trolley, and increases the mechanical approach and various expenses for use;

6) the method needs the crane to stand first and then weld the bottom plate, thus increasing the welding difficulty and being difficult to control the welding deformation degree;

7) the method needs to cut the gate and withdraw from the crane, so that rework work is generated, and the number of welding beads is increased;

8) the method needs to integrally hoist the tank top, increases the installation difficulty of the tank top, is not easy to control the ovality of the tank body, and increases the assembly difficulty of the tank top and the tank wall.
