Description

Technical Field

[0001] The utility model relates to the technical field of spherical tank assembly, in particular to an assembly tooling for small-diameter thin-walled spherical tanks. Background Technique

[0002] A spherical tank, also known as a spherical pressure vessel or spherical storage tank, is a pressure-bearing metal container used for mechanical and electrical installation, and it is mainly used to store various gases or liquefied gases with relatively high pressures.

[0003] The assembly methods of spherical tanks are divided into the bulk method, the zonal method, and the hemispherical method. The bulk method is applicable to the assembly of spherical tanks with a volume of more than 400 cubic meters, the zonal method is applicable to the assembly of spherical tanks with a volume of 400 - 1500 cubic meters, and the hemispherical method is applicable to the assembly of small spherical tanks with a volume of less than 400 cubic meters. When using the hemispherical method to assemble small spherical tanks, the spherical segments are assembled into the upper and lower hemispheres respectively and then assembled, and during welding, the longitudinal seams are welded first, and then the circumferential seams; the equatorial zone is welded first, and then the temperate zone and the polar plates; the large-bevel side is welded first, and then the small-bevel side; the welders are evenly and symmetrically distributed and welded synchronously.

[0004] However, when using the existing hemispherical method to assemble small spherical tanks, during assembly, the spherical segments are prone to deformation, and the misalignment of the circumferential seams of the strip electrodes is prone to exceed the standard.

[0005] Therefore, in view of the above problems, it is necessary for the applicant to design an assembly tooling for small-diameter thin-walled spherical tanks to solve the problems. Content of the Utility Model

[0012] Further, scale lines are drawn on the outer surface of the spherical piece, and a scale bar is fixedly arranged on one side of the vertical plate, and the scale bar is adapted to the scale lines.

[0013] Through the above structural design, during assembly, align the scale bar with the scale lines and install the spherical piece, which is convenient for improving the assembly rate and has high work efficiency.

The bottom surface of the connecting plate is fixedly provided with a bottom plate, and the bottom surface of the bottom plate is fixedly connected to the top surface of the base.

[0015] Through the above structural design, the support plate, the connecting plate and the bottom plate are convenient for supporting the support platform, thereby improving the stability and firmness of the support platform.

[0016] Further, reinforcement plates are detachably installed on both sides of the reinforcement rod, and the bottom surface of the reinforcement plate is flush with the bottom surface of the reinforcement rod.

[0017] Through the above structural design, the reinforcement plate is convenient for supporting the reinforcement rod, thereby improving the stability and firmness during the assembly of the spherical piece.

[0018] Further, a plurality of screws are arranged on the outer side of the reinforcement plate, and one end of the screw threadedly penetrates through the reinforcement rod or the base and extends into the interior of the reinforcement rod or the base.

One side of the welding plate 30 is detachably installed with a reinforcing rod 31, and the end of the reinforcing rod 31 away from the spherical segment 10 abuts against the base 1. The bottom surface of the support platform 20 is fixedly provided with a support plate 23, and a connecting plate 24 is integrally provided on the bottom surface of the support plate 23. The bottom surface of the connecting plate 24 is fixedly provided with a bottom plate 25, and the bottom surface of the bottom plate 25 is fixedly connected to the top surface of the base 1.
