Abstract
The utility model discloses a cylindrical body assembly tool comprising a first cylindrical body and a second cylindrical body. A flat steel loop is arranged to the outside of the second cylindrical body. Eight hexagonal bolts and nuts are evenly distributed on the flat steel loop. The nuts are welded to the flat steel loop. The flat steel loop is fixed to the second cylindrical body by the hexagonal bolts through the nuts. Two arc plates are disposed inside the first cylindrical body left and right in a symmetric manner, and a supporting rod is arranged between the two arc plates. The cylindrical body assembly tool is simple in structure and convenient to use, and can effectively control alignment tolerance and cylindrical body circularity when the two cylindrical bodies are grouped to be a pair so as to make the cylindrical bodies within a standard scope. Moreover, no scratch will be left on the cylindrical bodies to keep the cylindrical bodies nice in appearance, and the workload of workers is reduced.
Description
Technical field
The utility model relates to pressure vessel and manufactures field,, relate in particular to for different-diameter thin-wall barrel docking facilities, be specifically related to a kind of cylindrical shell assembly tool.
Background technology
At petrochemical equipment, manufacture field, if its main body frame in the various kinds of equipment such as boiler, reactor, tower, storage tank, shell-and-tube heat exchanger is equipment barrel, especially the equipment barrel such as boiler, reactor, tower, storage tank accounts for equipment and materials ratio and surpasses 70 percent, its device diameters routine from one meter with interior to more than several meters, weight of equipment also has one ton to more than hundred tons, and whole equipment barrel is that the single-unit cylindrical shell assembly welding by all size thickness forms.
Cylindrical shell is as one of main pressure parts of pressure vessel, and it mainly comprises cylindrical tube (being cylinder) and spherical cylindrical shell.During barrel diameter less (being generally less than 500mm), cylinder can be made of seamless steel pipe, now on cylindrical shell, there is no longitudinal seam; When diameter is larger, available steel plate is rolled into cylinder or with steel plate, on hydraulic press, is pressed into two semicircular cylinders on veneer reeling machine, then both are welded together, and forms full circle cylinder.When container length is longer, restriction due to steel plate book size, also just need first with steel plate, to roll some sections of cylindrical shells (a certain section of cylindrical shell is called a shell ring), by two or more shell ring assembly weldings, become again the cylindrical shell of Len req, attachment weld between shell ring and shell ring, due to its direction with drum shaft to vertical, be therefore called circumferential welded seam, be called for short girth joint.When cylindrical shell and cylindrical shell are assembled at present, conventionally utilize oblique angle steel group to or the auxiliary cylindrical shell assembling of wedge bridge group equity method, the wayward unfitness of butt joint of these traditional methods, weld gap is inhomogeneous, affects the total quality of weld seam, and on cylindrical shell, is welded oblique angle steel or wedge bridge can leave crator, not only need polishing, increase labour, also can affect the attractive in appearance of drum surface, drum surface occurs that above defect is unallowed.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of Cylinder assembly frock is provided, and it can effectively control unfitness of butt joint and the circularity of thin-wall barrel, make it in critical field, and can on cylindrical shell, not leave crator, and keep the attractive in appearance of cylindrical shell, reduce workman's labour intensity.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be:
A kind of cylindrical shell assembly tool, comprise the first cylindrical shell, the second cylindrical shell, the second cylindrical shell outside is furnished with a band steel circle, on band steel circle, be evenly equipped with hex bolts and nut, nut-welding is on band steel circle, hex bolts is fixed on band steel circle on the second cylindrical shell by nut, and described the first inner barrel is symmetrically set with two arc plates, between two arc plates, is provided with support bar.
Described arc plate is close to the first cylinder inboard wall.
The internal diameter of described band steel circle is greater than the external diameter of the second cylindrical shell.
On described band steel circle, be evenly equipped with eight groups of bolt assemblies that formed by hex bolts and nut.
There is respectively a support bar sleeve pipe at described support bar two ends.
The beneficial effects of the utility model are: by an inner barrel in cylindrical shell, put arc plate and support bar, this cylinder roundness is met the requirements, in another cylindrical shell outside, install band steel circle, screw bolt and nut again, the bolt assembly that bolts and nuts form is evenly arranged, dynamics used in the time of can making to regulate is consistent, can better coordinate assembling, this cylinder roundness is met the requirements, last two cylindrical shell assemblings; Contrast prior art, this tool structure is simple, and unfitness of butt joint and circularity that it can effectively control thin-wall barrel, make it in critical field, and can on cylindrical shell, not leave crator, keeps the attractive in appearance of cylindrical shell, reduces workman's labour intensity.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model cylindrical shell assembly tool cross-sectional schematic;
Fig. 2 is the utility model cylindrical shell assembly tool schematic top plan view.
Wherein: 1, the first cylindrical shell; 2, the second cylindrical shell; 3, band steel circle; 4, hex bolts; 5, nut; 6, arc plate; 7, support bar; 8, support bar sleeve pipe.
The specific embodiment
As shown in Figure 1, 2, a kind of cylindrical shell assembly tool, comprise the first cylindrical shell 1, the second cylindrical shell 2, the second cylindrical shell 2 outsides are furnished with a band steel circle 3, on band steel circle 3, be evenly equipped with eight groups of hex bolts 4 and nut 5, nut 5 is welded on band steel circle 3, hex bolts 4 is fixed on band steel circle 3 on the second cylindrical shell 2 by nut 5, described the first cylindrical shell 2 inside are symmetrically set with two arc plates 6, arc plate 6 is close to the first cylindrical shell 1 inwall, between two arc plates 6, be provided with support bar 7, there is respectively a support bar sleeve pipe 8 at support bar 7 two ends; By coordinating of support bar 7 and arc plate 6, regulate the circularity of the first cylindrical shell 1, then, by regulating hex bolts 4 to adjust the circularity of the second cylindrical shells 2, finally the wrong variable of upper and lower two cylindrical shells is adjusted to the scope of permission.
Most preferred embodiment of the present utility model is illustrated, and the various variations of being made by those of ordinary skills or remodeling can not depart from scope of the present utility model.
