Description

Technical Field

[0001] This utility model relates to the technical field of anti-deformation device for welding fan-shaped base plates, specifically an anti-deformation device for welding fan-shaped base plates. Background Technology

[0002] The 58m thickener has 30 spans of fan-shaped base plates, each composed of 13 fan-shaped blocks of varying sizes. After the fan-shaped blocks of a single span are assembled, deformation frequently occurs during both hoisting and overall assembly. Therefore, welding the fan-shaped base plates is a crucial step in thickener construction, and preventing deformation during welding has become a problem that needs to be solved during installation. Currently, there are no ready-made anti-deformation devices for fan-shaped base plates on the market.

[0003] To address the aforementioned issues, a fan-shaped base plate welding anti-deformation device is proposed. Summary of the Invention

[0005] The specific solution of this utility model is: a fan-shaped base plate welding anti-deformation device, comprising: a fan-shaped base plate, wherein the fan-shaped base plate has an inner arc at one end near the center and an outer arc at one end away from the center, the fan-shaped base plate is welded from a number of fan-shaped blocks, and vertical reinforcing ribs perpendicular to the weld seam of adjacent fan-shaped blocks are provided, the vertical reinforcing ribs evenly dividing the weld seam of adjacent fan-shaped blocks into a number of segments, and the fan-shaped base plate is also provided with a number of transverse reinforcing ribs, the transverse reinforcing ribs being evenly distributed from the middle of the fan-shaped base plate toward the outer arc direction.

[0006] Furthermore, the vertical reinforcing rib is a 14a channel steel with a length of 400 mm.

[0007] Furthermore, there are three transverse reinforcing ribs, specifically including: a short transverse rib, a middle transverse rib, and a long transverse rib. All transverse reinforcing ribs are made of 14a channel steel. The length of the short transverse rib is 2300 mm; the length of the middle transverse rib is 3300 mm; and the length of the long transverse rib is 4500 mm.

[0008] Furthermore, the transverse reinforcing ribs are horizontally arranged in the middle of the corresponding sector blocks, staggered from the vertical reinforcing ribs.

[0009] Furthermore, the connection between the vertical reinforcing rib and the horizontal reinforcing rib is welded using a full welding process.

[0010] Furthermore, the sector-shaped block is made of low-alloy steel.

[0011] Furthermore, the surfaces of both the vertical and horizontal reinforcing ribs are coated with an anti-corrosion coating.

[0012] This utility model has the following beneficial effects:

[0013] This utility model has a simple structure and is easy to process. Vertical and horizontal reinforcing ribs are used to weld and reinforce the fan-shaped base plate, effectively improving its strength. Short, medium, and long horizontal ribs are pre-positioned and installed with the fan-shaped blocks via welding positioning blocks. The spacing of the positioning blocks is rationally set according to the size of the fan-shaped blocks and the arrangement requirements of the reinforcing ribs, allowing for precise determination of the reinforcing rib installation positions. This not only improves welding efficiency and reduces adjustment time during installation but also enhances the overall stability of the device, enabling the reinforcing ribs to play a more efficient role in preventing deformation.
