Description

Technical Field

[0001] This utility model relates to a split flange splicing and welding platform device, belonging to the field of split flange splicing and welding technology. Background Technology

[0002] Large flanges with diameters of 1-6 meters require the welding of several arc-shaped plates to form a large flange during production. Due to the large size of the large flange, after the top surface is welded, it needs to be flipped over to perform back welding on the corresponding welding positions on the back. During the flipping process after the front welding is completed, the large flange is prone to deformation or damage to the existing welds. Therefore, it is crucial to develop a split flange splicing and welding platform device. Utility Model Content

[0005] Furthermore, the platform is provided with connection holes for fixing the arc-shaped plate, and the connection holes are located on both sides of the welding groove.

[0006] Furthermore, the connecting holes are arranged in a circular array around the center of the platform, with the center of the platform coinciding with the center of the flange, and the distance between the connecting holes and the center of the flange is 0.4-31m.

[0007] Furthermore, the arc-shaped plate is detachably connected to the connection holes on both sides of the welding groove via a fixing buckle.

[0008] Furthermore, the welding grooves are arranged in a ring around the center of the platform, with the center of the platform coinciding with the center of the flange, and the distance between the welding grooves and the center of the flange is 0.3-32m.

[0009] Furthermore, each side of the support body is provided with at least two fixedly connected lifting lugs.

[0010] Furthermore, a support reinforcement body is provided below the platform to support the platform, and the edge of the support reinforcement body is fixedly connected to the bracket body.

[0011] Furthermore, the supporting reinforcement body includes a central support frame fixedly connected to the bottom center of the platform. Several sets of symmetrically arranged stiffeners are provided between the central support frame and the inner edge of the support body. The symmetrical stiffeners are located on both sides of the support welding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This application uses a platform to fix the arc plate, and the platform combined with the support body enables quick and effective flipping. The fixed connection between the arc plate and the platform effectively avoids the problem of deformation and damage of large flanges during the flipping process. 2. The back side of the joint between adjacent arc-shaped plates is welded by the welding groove, realizing rapid welding of the front and back sides of large flanges; 3.

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] like Figures 1-4As shown, a split-type flange splicing and welding platform device includes a platform 2 for fixing several arc-shaped plates 8, a fixedly connected support body 1 below the platform 2, and several welding grooves 3 for welding adjacent arc-shaped plates 8. In application, six arc-shaped plates 8 are first spliced ​​and arranged on the platform 2, with adjacent arc-shaped plates 8 butt-jointed on the welding grooves 3. The arc-shaped plates 8 are fixed to the platform 2 by a fixing structure. After front welding of the butt joints of adjacent arc-shaped plates 8, the support body 1 and platform 2 are flipped to the back of the platform using an overhead crane or other equipment capable of lifting the support body 1 (the overhead crane or lifting equipment is existing equipment used to assist in the front-to-back flipping of this application). At this time, the front of the arc-shaped plates 8 and platform 2 can be placed on other platforms, bodies, or other supports. The butt joints of adjacent arc-shaped plates 8 are then welded to the back using the welding grooves 3, achieving rapid front-to-back welding of large flanges. The platform 2 combined with the support body 1 achieves rapid and effective flipping, and the fixed connection between the arc-shaped plates 8 and platform 2 effectively avoids the problem of deformation and damage to large flanges during the flipping process.

[0020] The platform 2 is provided with connecting holes 4 for fixing the arc-shaped plate 8, and the connecting holes 4 are located on both sides of the welding groove 3. The fixing structure is detachably connected to the connecting holes 4 by bolts to ensure that the arc-shaped plate 8 is effectively fixed to the platform 2.

[0021] The connecting holes 4 are arranged in a ring around the center of platform 2, with the center of platform 2 coinciding with the center of the flange. The distance between the connecting holes 4 and the center of the flange is 0.4-31m. This application can be used to quickly complete the splicing and welding of large flanges ranging from 1 to 6 meters.

[0022] The arc-shaped plate 8 is detachably connected to the connection holes 4 on both sides of the welding groove 3 via the fixing buckle 7.

[0023] The welding grooves 3 are arranged in a ring around the center of the platform 2, with the center of the platform 2 coinciding with the center of the flange. The distance between the welding grooves 3 and the center of the flange is 0.3-32m.

[0024] Each side of the support body 1 is provided with at least two fixedly connected lifting lugs 5.

[0025] The platform 2 is provided with a support reinforcement body below it, and the edge of the support reinforcement body is fixedly connected to the bracket body 1.

[0026] The supporting structure includes a central support frame 6 fixedly connected to the central bottom surface of the platform 2. Several sets of symmetrically arranged stiffening plates 9 are provided between the central support frame 6 and the inner edge of the support body 1. These symmetrical stiffening plates 9 are located on both sides of the supporting welding groove 3. The symmetrical stiffening plates 9 support both sides of the welding groove 3. The central support frame 6 effectively supports the central part of the platform 2.

[0027] This application uses platform 2 to fix the arc plate 8, and the platform 2 combined with the support body 1 to achieve rapid and effective flipping. The fixed connection between the arc plate 8 and platform 2 effectively avoids the problem of deformation and damage of large flanges during flipping. The welding groove 3 is used to perform back welding at the joint of adjacent arc plates 8, realizing rapid welding of the front and back sides of large flanges. This application can be used to quickly complete the splicing and welding of large flanges of 1-6 meters. The two symmetrical stiffening plates 9 provide effective support on both sides of the welding groove 3.
