A slag removal device for submerged arc welding of steel structures

Abstract

This utility model relates to the field of welding technology structures, and particularly to a slag removal device for submerged arc welding of steel structures. It includes a support, a tilting platform, a slag collection box, and a collection tray. In this utility model, a U-rib steel plate is placed on the tilting platform, and a clamping device and a limiting block are used to quickly clamp and limit both sides of the U-rib steel plate's length. Then, the tilting platform is rotated so that one side of the U-rib steel plate rotates upwards, causing the other side to rotate downwards. The welding slag inside automatically falls from the other side of the U-rib steel plate into the slag collection box. The entire process is relatively smooth and requires no multiple operators to quickly clean the welding slag from the U-rib steel plate, thereby improving factory production efficiency. Simultaneously, the clamping device and limiting block quickly clamp and limit both sides of the U-rib steel plate's length, avoiding the cumbersome connection process between the crane and the U-rib steel plate unit before hoisting, and ensuring the stability of the U-rib steel plate during the subsequent tilting of the platform, saving significant manpower.

Description

Technical Field

[0001] This utility model relates to the field of welding technology and structure, and in particular to a slag removal device for submerged arc welding of steel structures. Background Technology

[0002] Submerged arc welding (SAW) is a welding method in which an electric arc burns beneath a layer of flux. Its inherent advantages, such as stable weld quality, high welding productivity, and minimal arc light and fumes, make it a primary welding method in the fabrication of important steel structures such as pressure vessels, pipe sections, and box girder columns. In recent years, although many new, efficient, and high-quality welding methods have emerged, the application areas of SAW have remained unaffected. In terms of the share of deposited metal weight among various fusion welding methods, SAW accounts for approximately 10%, and this percentage has remained relatively stable over the years.

[0003] Submerged arc welding (SAW) has been used in existing technologies to weld the inner fillet welds between the U-rib and the panel. However, SAW has two drawbacks: firstly, it generates a layer of slag on the surface of the inner weld of the U-rib, requiring timely cleaning to ensure the quality of the U-rib steel plate unit is not affected; secondly, it requires flux during welding, and the amount of flux applied exceeds the amount consumed during welding, necessitating the recycling of excess flux to reduce welding costs.

[0004] The current manual cleaning procedure for U-rib submerged arc welds involves lifting one end of the welded U-rib steel plate unit using hoisting equipment, with the other end facing downwards to allow the welding slag and flux inside the U-rib steel plate to be poured out. This hoisting operation is complex due to the small internal space of the U-rib and its relatively long length. It also requires multiple workers to cooperate in lifting one end and tilting the other end downwards, resulting in low production efficiency for U-rib steel plate units. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steel structure submerged arc welding slag removal device, which solves the problems of the existing manual cleaning of welding slag and excess flux inside the U-rib submerged arc weld, which is cumbersome before hoisting and connecting with the U-rib steel plate unit, and ensuring the stability of the U-rib steel plate unit during hoisting, requiring multiple people to cooperate and resulting in low production efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a steel structure submerged arc welding slag removal device, the innovation of which is: including a support, a tilting platform, a slag collection box and a collection tray; The flipping platform is set horizontally, and U-rib steel plates are laid on the flipping platform, with the U-rib steel plates aligned with the length direction of the flipping platform. The support pier is vertically installed at the bottom of the tilting platform; The slag collection box is located below one of the length sides of the tilting platform, and the tilting platform is rotatably connected to the slag collection box; The collection tray is located below the outlet of the slag collection box.

[0007] Furthermore, the length of the side of the flipping platform closest to the slag collection box is greater than the length of the other side, which is used to adapt to the width of the U-rib steel plate and the slag collection box, ensuring that all welding slag on the U-rib steel plate falls into the slag collection box and avoids welding slag falling on the ground and causing pollution.

[0008] Furthermore, a lifting lug is installed on the side of the tilting platform away from the slag collection box for connecting with a crane, thereby enabling the tilting platform to tilt.

[0009] Furthermore, an ear plate is installed on the bottom side of the flipping platform near the slag collection box. A vertical connecting part is provided on both sides of the ear plate on the slag collection box, and the vertical connecting part is connected to the ear plate by a pin.

[0010] Furthermore, it also includes a clamping device and a limiting block. The limiting block is located on one side of the tilting platform near the slag collection box, and the clamping device is located on the other side of the tilting platform. The clamping device and the limiting block work together to clamp and limit the length of the U-rib steel plate on both sides, preventing the U-rib steel plate from shifting or falling off during the tilting process of the tilting platform, thus improving the safety of the workers.

[0011] Furthermore, the limiting block is an L-shaped block fixed on the flipping platform, with a gap between the bottom end of its upper horizontal section and the flipping platform. The pressing device includes an upper fixed plate, a side plate, and a pressing block. The upper fixed plate is horizontally arranged on the flipping platform. The side plates are symmetrically and threadedly connected to both sides of the upper fixed plate. The side plates are L-shaped plates, and the bottom of their upper horizontal section is higher than the top surface of the flipping platform. A groove is provided in the middle of the bottom of their horizontal section, and the groove is used to just accommodate the pressing block.

[0012] The advantages of this utility model are: 1) In this utility model, by placing the U-rib steel plate on the flipping platform, and using the pressing device and the limiting block to quickly press and limit both sides of the length of the U-rib steel plate, and then rotating the flipping platform to make one side of the U-rib steel plate rotate upward, so that the other side of the U-rib steel plate rotates downward, the welding slag inside will automatically fall from the other side of the U-rib steel plate into the slag collection box. The whole process is relatively stable and can quickly clean the welding slag of the U-rib steel plate without the need for multiple people to operate, thereby improving the production efficiency of the factory.

[0013] 2) In this utility model, the clamping device and the limiting block are used simultaneously to quickly clamp and limit the length of the U-rib steel plate on both sides, avoiding the cumbersome connection process between the crane and the U-rib steel plate unit before hoisting, and ensuring the stability of the U-rib steel plate during the subsequent flipping process of the flipping platform, which can save a lot of manpower.

[0014] 3) In this utility model, the length of the side of the flipping platform closest to the slag collection box is greater than the length of the other side, which is used to adapt to the width of the U-rib steel plate and the slag collection box, ensuring that all welding slag on the U-rib steel plate falls into the slag collection box, and avoiding the generation of welding slag falling on the ground and causing pollution.

[0015] 4) Lifting lugs are also installed on the side of the tilting platform away from the slag collection box, which are used to connect with the crane to achieve the tilting of the platform. Attached Figure Description

An extension rod is symmetrically provided at both ends on the side of the main body near the slag collection box 3. An inclined reinforcing rib plate is also fixed between the extension rod and the main body, so that the length of the side of the tilting platform 1 near the slag collection box 3 is greater than the length of the other side, and the length of the side of the tilting platform 1 near the slag collection box 3 is greater than the width of the U-rib steel plate 9. This is to adapt to the width of the U-rib steel plate 9 and the slag collection box 3, ensuring that all welding slag on the U-rib steel plate 9 falls into the slag collection box 3, and avoiding welding slag falling on the ground and causing pollution.

[0026] A lifting lug is also installed on the side of the tilting platform 1 away from the slag collection box 3, which is used to connect with the crane and thus realize the tilting of the tilting platform 1.

[0027] An ear plate is installed on the bottom side of the tilting platform 1 near the slag collection box 3. A vertical connecting plate 8 is provided on both sides of the ear plate on the slag collection box 3, and the vertical connecting plate 8 is rotatably connected to the ear plate through a pin 5.

[0028] Multiple supports 2 are equidistantly spaced and vertically installed at the bottom of the tilting platform 1.

[0029] The limiting block 7 is set on one side of the tilting platform 1 near the slag collection box 3, and the pressing device 4 is set on the other side of the tilting platform 1. The pressing device 4 and the limiting block 7 work together to press and limit the length of the U-rib steel plate 9 on both sides, so as to prevent the U-rib steel plate 9 from shifting or falling off during the tilting process of the tilting platform 1, and improve the safety of the staff.

[0030] The limiting block 7 is an L-shaped block fixed on the flipping platform 1, with a gap between the bottom of its upper horizontal section and the flipping platform 1 that is just enough to accommodate the panel of the U-rib steel plate 9.

[0031] The pressing device 4 includes an upper fixed plate 41, a side plate 42, and a pressing block 43. The upper fixed plate 41 is horizontally arranged on the flipping platform 1.

The side plates 42 are L-shaped plates, and the bottom of their upper horizontal section is higher than the top surface of the flipping platform 1. A groove is provided in the middle of the bottom of their horizontal section, which is used to just accommodate the pressing block 43.

[0032] The working principle of this patent: The U-rib steel plate 9 is placed horizontally on the flipping platform 1. Then, the clamping device 4 and the limiting block 7 are used to quickly clamp and limit the length of both sides of the U-rib steel plate 9. The lifting lug is connected to the crane, and the crane is used to drive the flipping platform 1 to move upward on this side, thereby realizing that one side of the U-rib steel plate 9 rotates upward and the other side of the U-rib steel plate 9 rotates downward. The welding slag inside will automatically fall from the other side of the U-rib steel plate 9 into the slag collection box 3. The whole process is relatively smooth and can quickly clean the welding slag of the U-rib steel plate 9 without the need for multiple people to operate, thereby improving the production efficiency of the factory.
