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
The present invention relates to a kind of large-sized flange splicing and use frock, relate in particular to a kind of large-sized flange splicing and use support platform.
Background technology
Platform be meant produce and work progress in, some operation of operation for ease and the workbench that is provided with, what have can move, what have can go up and down.Along with the high speed development of mechanical industry, the manufacturing of main equipment is more and more general, in manufacture process, runs into some technical problems unavoidably; Such as material is 0Cr18Ni9, and thickness is 100mm, and width is 150mm; Diameter is the austenitic stainless steel vacuum flange of 4000mm, transports and practice thrift manufactured materials for ease, tends to adopt it is divided into several little parts; Splice at the scene, during this large-scale flange of on-the-spot splicing, normal at present the employing is placed on the support platform; Splice then; But after the splicing of traditional method, the roundness of flange and flatness can exceed the margin of tolerance of permission, so traditional support platform can not play the purpose that makes things convenient for the flange splicing.
Summary of the invention
The objective of the invention is to address the above problem; Provide a kind of large-sized flange splicing to use support platform; It can make things convenient for the scene splicing work of large-sized flange; The effectively splicing of control flange distortion makes flange splicing back roundness and flatness in the margin of tolerance that allows, have simple in structure be convenient to the advantage that flange splices.
The objective of the invention is to realize through following technical scheme:
Support platform is used in a kind of large-sized flange splicing; Comprise reinforcement, four arc plates; Said reinforcement is processed circle; Evenly weld four arc plates on the said reinforcement, be provided with welding between said four arc plates and use gap, and the inboard of said four arc plates is provided with the cross fixed support.
It is that 30mm, width are processed than the flat board of the big 100mm of difference of external diameter in the flange that said arc plate adopts thickness.
It is 10mm that said reinforcement adopts thickness, and width is that the flat board of 150mm is processed.
Beneficial effect of the present invention is: through four arc plates are assembled with reinforcement; And the cross fixed support is set four arc plate inboards; Can play good supporting role to the flange splicing; Prevent the welding deformation of flange when splicing, guarantee that spliced flange formation degree and roundness are in the margin of tolerance that allows; When arc plate and reinforcement assembling; Leave welding between arc plate and the arc plate and use gap; Can make things convenient for carrying out smoothly of welding job, the contrast prior art applied to the on-the-spot splicing of large-sized flange through splicing with support platform; Can reduce and make the employed raw material of flange and reduce cost of transportation, this support platform has simple in structure and is convenient to the advantage that flange splices.

Fig. 2 is the schematic perspective view of a kind of large-sized flange splicing of the present invention with support platform.
Among the figure:
1, arc plate; 2, reinforcement; 3, fixed support, 4, flange.
The specific embodiment
In Fig. 1～2 illustrated embodiments, support platform is used in a kind of large-sized flange splicing of the present invention, comprises reinforcement 2 and four arc plates 1; It is that 30mm, width are processed than the flat board of the big 100mm of difference of external diameter in the flange that arc plate 1 adopts thickness, and it is that 10mm, width are that the flat board of 150mm is processed that reinforcement 2 adopts thickness, and reinforcement 2 is processed circle; Four arc plates 1 evenly are welded on the reinforcement 2, be provided with welding between four arc plates 1 and use gap, and the inboard of four arc plates 1 is provided with cross fixed support 3; Find out the center of circle of support platform during work; With the horizontal plane of center of circle calibration support platform, the internal diameter and the external diameter datum line of the flange 4 that on flat surface, draws at last are for the flange of stainless steel material; Its internal diameter and external diameter datum line will amplify 10mm; As flange 4 spliced welding allowances for shrinkage, through this support platform being applied to the scene splicing of large-sized flange, can be so that spliced flange formation degree and roundness remain in the margin of tolerance of permission.
