Description

Desulfurization tower barrel construction auxiliary fixtures

Technical Field

The invention relates to the field of ship design and ship construction, in particular to an auxiliary tool for assisting construction of a desulfurization tower barrel in the construction process of a desulfurization tower.

Background

At present, in the shipbuilding industry, a desulfurizing tower becomes an essential part of a ship body structure. The material of the desulfurizing tower is special, and is mostly super austenite, duplex stainless steel and other materials, the material is special, in order to prevent corrosion, the material is strictly forbidden to nail weld in the construction process, and is strictly forbidden to contact all carbon steel materials; meanwhile, the precision such as roundness and straightness of the cylinder body of the desulfurizing tower is also very high, great difficulty is brought to the construction of the cylinder body of the desulfurizing tower, particularly, the ovality caused by the gravity of the cylinder body is very serious in the construction of the cylinder body with a large diameter, the roundness root of the cylinder body cannot be guaranteed when the cylinder sections are combined, and great troubles are brought to assembly construction, hoisting and transferring and the like.

Because of the major diameter desulfurizing tower height is higher, surpasss the jack-up height of general factory building, the barrel girth welding of being convenient for simultaneously, the desulfurizing tower adopts the form of "crouching to make" to build mostly, directly places the desulfurizing tower barrel and carries out the construction on the gyro wheel bed-jig. But receive desulfurizing tower self gravity restriction, the desulfurizing tower is violently put not only whole ovality after on the gyro wheel bed-jig very big, simultaneously because of the barrel is placed and is belonged to barrel single-point atress on the gyro wheel bed-jig, desulfurizing tower tubular structure panel thickness is still thinner, the drum appears in the barrel extremely easily at rotatory in-process, and this drum later stage can't be restoreed, can only trade the board and handle, and traditional construction mode can not reach anticipated effect, brings a lot of puzzlements for the site operation. Simultaneously, because of the nail welding of desulfurizing tower self prohibition, the unable welding handling of desulfurizing tower tube structure self stands up the lug, also brings inconvenience for the barrel handling.

Disclosure of Invention

In order to solve the problems, the invention provides an auxiliary tool for the construction of a desulfurization tower cylinder, which aims to achieve the purposes of facilitating the rotation of the desulfurization tower cylinder on a roller jig frame and avoiding damaging the outer surface of the desulfurization tower cylinder, and adopts the technical scheme that:

a desulfurization tower cylinder body construction auxiliary tool comprises a circular outer ring plate and a circular inner ring plate, wherein the outer ring plate and the inner ring plate are concentric circles, the diameter of the outer ring plate is larger than that of the inner ring plate, the inner ring plate is arranged on the inner side of the outer ring plate, the outer ring plate and the inner ring plate are butted by two semicircular components and fixedly connected through bolts to form a complete circular outer ring plate and an integral circular inner ring plate; the outer ring rib plates are wrapped on the outer surfaces of the outer ring plates, the outer ring rib plates are wrapped on the outer surfaces of the inner ring plates, white steel linings are arranged on the inner surfaces of the inner ring plates, and the white steel linings are tightly attached to the inner ring plates; the white steel lining is in contact with the desulfurization tower barrel. The outer ring rib plate plays a role in strengthening the outer ring plate, and the inner ring rib plate plays a role in strengthening the inner ring plate, so that the firmness of the device in the construction and use process is ensured. The white steel lining contacts with the desulfurizing tower cylinder body to isolate the desulfurizing tower cylinder body from the carbon steel, so that the raw material corrosion caused by the contact of the carbon steel and stainless steel made of super austenite or duplex stainless steel and the like is prevented, and the effect of protecting the desulfurizing tower cylinder body is achieved.

The gusset has further strengthened the structural stability between interior crown plate and the outer crown plate, prevents that the frock from taking place to warp in the use to link into an organic whole through the gusset with interior crown plate and outer crown plate.

According to the auxiliary tool for construction of the desulfurization tower cylinder body, furthermore, eye plates are arranged at two ends of a semicircular component forming the outer ring plate and the inner ring plate, one end of each eye plate is connected with the outer ring plate in a welded mode, the other end of each eye plate is connected with the inner ring plate in a welded mode, round holes are formed in the eye plates, and bolts penetrate through the round holes. The eye plate fixedly connects the inner ring plate and the outer ring plate together, and the eye plate integrally connects the two semicircular components to form a complete circular inner ring plate and an integral circular outer ring plate.

Above-mentioned construction auxiliary fixtures of desulfurization tower barrel, further, outer annular plate surface is provided with two outer ring gusset. There is the distance between two outer loop gusset, and when the outer loop gusset played additional strengthening, can also play spacing effect, the frock cover was established in the desulfurizing tower barrel outside, drives the barrel and rolls, prevents that the barrel from taking place the skew at rotatory in-process, causes desulfurizing tower barrel position to change.

Above-mentioned construction auxiliary fixtures of tower body of desulfurization tower, further, the interior crown plate surface is provided with two interior ring gusset.

Above-mentioned desulfurization tower barrel construction auxiliary fixtures, further, be fixed with 4 lugs outside outer crown plate, equidistant. The lifting lugs can be any number, and preferably, 4 lifting lugs are arranged on the outer ring plate at equal intervals. The lifting and turning-over transportation of the tool and the auxiliary desulfurizing tower is facilitated.

Above-mentioned a desulfurization tower barrel construction auxiliary fixtures, further, the lug with eye plate welded connection. The 4 lifting lugs are arranged on the outer surface of the outer ring plate at equal intervals, wherein the two lifting lugs are just arranged at the positions of the eye plates and are connected with the eye plates in a welding mode.

Above-mentioned desulfurization tower barrel construction auxiliary fixtures, further, the white steel inside lining diameter with desulfurization tower barrel diameter is the same. The diameter of white steel inside lining is the same with the barrel diameter, guarantees that frock and barrel closely laminate, prevents that the barrel from producing the displacement at rotatory in-process, and the barrel surface from producing the scraping vestige, destroys the desulfurizing tower barrel.

The desulfurization tower barrel is simple in structure, the desulfurization tower barrel is protected from deformation, the outer surface of the barrel is not corroded, the outer surface of the barrel is not scratched, the tool can be repeatedly used, the storage is convenient, the construction cost is saved, and the construction environment is protected.
