A support platform for splicing large flanges

Abstract

The invention discloses a supporting platform used for splicing large flanges. The supporting platform comprises a reinforcing rib and four arc plates, wherein the reinforcing rib is made into a circular reinforcing rib; the four arc plates are uniformly welded on the reinforcing rib; nicks for welding are formed among the four arc plates; and cruciform fixed supports are arranged at the inner sides of the four arc plates. Since the four arc plates are assembled by using the reinforcing rib and the cruciform fixed supports are arranged at the inner sides of the four arc plates, an excellent supporting function is achieved for flange splicing, welding deformation of the flanges can be prevented during a splicing process, and evenness and roundness of the spiced flanges are ensured to be in an allowed tolerance margin. When the arc plates and the reinforcing rib are assembled, since the nicks for welding are reserved between the arc plates and the reinforcing rib, welding operation can be performed smoothly. Compared with the prior art, the supporting platform has the advantages of simple structure and convenience in flange splicing.

Description

technical field [0001] The invention relates to a tooling for splicing large flanges, in particular to a supporting platform for splicing large flanges. Background technique [0002] The platform refers to the workbench set up for the convenience of operating certain processes during the production and construction process, some of which can be moved, and some can be raised and lowered. With the rapid development of the machinery industry, the manufacture of large-scale equipment is becoming more and more common. It is inevitable to encounter some technical problems in the manufacturing process. For example, the material is 0Cr18Ni9, the thickness is 100mm, the width is 150mm, and the diameter is 4000mm. Austenitic stainless steel In order to facilitate transportation and save manufacturing materials, vacuum flanges are often divided into several small parts and spliced ​​on site. When splicing such large flanges on site, it is often used to place them on a support However,...

With the rapid development of the machinery industry, the manufacture of large-scale equipment is becoming more and more common. It is inevitable to encounter some technical problems in the manufacturing process. For example, the material is 0Cr18Ni9, the thickness is 100mm, the width is 150mm, and the diameter is 4000mm. Austenitic stainless steel In order to facilitate transportation and save manufacturing materials, vacuum flanges are often divided into several small parts and spliced ​​on site. When splicing such large flanges on site, it is often used to place them on a support platform, and then splicing, but after the traditional splicing method, the roundness and flatness of the flange will exceed the allowable tolerance range, so the traditional support platform cannot serve the purpose of facilitating flange splicing
