Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, in particular to a submerged arc welding butt joint structure of thick plates of steel structures for construction. Background Art

[0002] Steel structure is one of the more commonly used building structure types in today's society. Compared with traditional building types, it is easier to construct, has a shorter construction period, and has strong resistance to deformation. Therefore, steel structure is widely used in large factories, stadiums, high-rise buildings and other fields. Welding is one of the connection methods between the various components of steel structure, and submerged arc welding is usually used when welding steel structures. Before submerged arc welding of steel structures, the components need to be butt-jointed.

[0003] However, the current submerged arc welding butt joint structure of steel structures has some shortcomings. For example, the application number is 202222170021.0, which discloses "a submerged arc welding butt joint structure of thick steel structure plates for construction, specifically relating to the technical field of steel structure welding, including a base plate, the four corners of the bottom end of the base plate are respectively fixedly connected with support columns, and connecting plates are respectively arranged on both sides of the top of the base plate. The utility model is provided with an adjustment mechanism at the middle position of the bottom end of the base plate. When the thick steel structure plates need to be butt jointed, a servo motor fixedly connected to the top of one side of the fixed shell is started to drive the adjustment shaft to rotate inside the fixed shell, and the rotation of the adjustment shaft drives the adjustment shaft to rotate. The adjusting blocks move toward each other outside the adjusting blocks, and the connecting plates are driven to move by the connecting rods while the adjusting blocks move, thereby pushing the thick plates of the steel structure to be butted together, and the sliding structure formed by the slider fixedly connected to the bottom end of the adjusting blocks and the limiting sliding rods can limit and stabilize the adjusting blocks while not hindering their movement, thereby achieving the purpose of stably and quickly butting the thick plates for easy welding. When in use, it is necessary to rotate the adjusting disk of the clamping and fixing structure, and there are four adjusting disks, so when clamping and fixing the thick plates, it is necessary to manually operate the four adjusting disks, and after welding, the four adjusting disks need to be rotated again, which is more troublesome.

[0014] In the utility model, by arranging the push plate, lifting plate, pressure plate and rack to cooperate with each other, when the thick plate is placed on the placing table in front of the push plate, the adjusting motor is started by using an external device, and the adjusting motor drives the double-headed screw to rotate. At this time, the two push plates will approach each other. When the push plate moves, the gear rotates under the action of the rack, and the rotating gear drives the threaded rod to rotate. At this time, the lifting plate will drive the pressure plate to continuously descend. When the lifting plate drops to a certain height, the pressure plate will contact the thick plate.

At this time, the descending lifting plate will compress the spring, so that the pressure plate is more firmly pressed on the upper surface of the thick plate until the two thick plates are butt-joined together. When the welding is completed, as the push plates move away from each other, the lifting plate will drive the pressure plate to rise, thereby contacting the state where the pressure plate is pressed on the thick plate. This docking method is not only convenient, but also does not require manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

When the push plate 2 moves, the gear 204 rotates under the urging of the rack 5.

[0022] It should be noted that the utility model is a submerged arc welding butt joint structure for thick plates of steel structures for construction. When in use, after the thick plate is placed on the placement table 1 in front of the push plate 2, the adjustment motor 6 is started by using an external device, and the adjustment motor 6 drives the double-headed screw to rotate.
