Technical Field

[0001] The utility model relates to the technical field of steel box girder welding, in particular to a welding device for internal partitions of steel box girders. Background Technique

[0002] A steel box girder, also known as a steel plate box girder, is a commonly used structural form for long-span bridges. A steel box girder is generally formed by connecting a top plate, a bottom plate, webs, transverse partitions, longitudinal partitions, stiffeners, etc. through full welding. Since the four sides of the partition need to be welded to the top plate, the bottom plate, the webs, and the longitudinal partitions respectively, and the partition is a single steel plate before welding and is not connected to the top plate, etc., a fixing device is required to fix the partition during welding.

[0003] In the existing welding process of the internal partition of the steel box girder, the partition is manually aligned with the welding position in the inner cavity of the steel box girder by hand, and then welded. In the above method, during the welding process, since the welder needs to operate the welding torch with one hand and fix the partition with the other hand, it is not only inconvenient for the welder, but also affects the welding effect. Therefore, there is an urgent need for a welding device for the internal partition of the steel box girder to solve the above problems. Summary of the Invention

At the bottom end inside the fixed sleeve 2, a driving motor 11 is installed. On the output shaft of the driving motor 11, a screw rod 12 is installed. The driving motor 11 drives the screw rod 12 to rotate. A screw block 13 is sleeved on the screw rod 12. On both sides of the top end of the screw block 13, two groups of linkage rods 3 are symmetrically fixed. The top ends of the linkage rods 3 are welded with lifting sleeves 4. During the rotation of the screw rod 12, the screw block 13 adjusts the lifting sleeve 4 through the linkage rods 3 under the action of the thread and the limitation of the fixed sleeve 2, and then adjusts the height of the electromagnet I 6 according to the specification of the partition. At the top end of the lifting sleeve 4, a bearing frame 5 is fixed. On the bearing frame 5, four groups of electromagnets I 6 are installed. When the electromagnets I 6 are energized, they can adsorb and fix the partition.

[0030] As Figures 1-3 shown in the figure, in this embodiment, the electromagnets II 9 are fixed to both sides of the bottom end of the base 1 by bolts. A battery pack is built in the base 1. On one side wall of the base 1, a charging hole 10 is reserved. The charging hole 10 is electrically connected to the battery pack. The driving motor 11 is fixed to the bottom end inside the fixed sleeve 2 by bolts. The output shaft of the driving motor 11 is fixedly connected to the bottom end of the screw rod 12. The top end of the screw rod 12 is rotatably connected to the top end inner wall of the fixed sleeve 2. The screw block 13 is threadedly connected to the screw rod 12. The specification of the screw block 13 matches the specification inside the fixed sleeve 2. The linkage rods 3 are welded to both sides of the top end of the screw block 13. The linkage rods 3 penetrate through the fixed sleeve 2.

[0031] As Figures 1-3 shown in the figure, in this embodiment, the bearing frame 5 is connected to the lifting sleeve 4 by bolts, and the electromagnet I 6 is connected to the bearing frame 5 by screws. On one side wall of the fixed sleeve 2, a handle 7 is welded. On the handle 7, an operation button 8 is installed. The handle 7 facilitates carrying the device.
