[0004] The aforementioned automatic welding device reduces safety hazards by setting up baffles and protective frames, but it cannot adapt to the welding of stirrups with curved structures during the welding process, resulting in the inconvenience of welding the stirrups of the pipe segments. To address this, we provide a pipe segment stirrup welding device. Utility Model Content

[0005] The purpose of this utility model is to provide a segment stirrup welding device to solve the problem mentioned in the background art that the existing automatic welding device reduces safety hazards by setting baffles and protective frame structures, but cannot adapt to the welding of curved stirrups during the welding process, resulting in the inconvenience of segment stirrup welding.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a segment stirrup welding device, comprising a base platform, two support seats welded to the upper end of the base platform, a curved frame welded to the upper end of the two support seats, a movable arc platform movably disposed in the inner arc groove of the curved frame, and a support frame welded to the upper end of the movable arc platform.

[0007] Also includes:

[0008] A bearing seat plate is located at the rear end of the support frame, and a first cylinder is fixedly mounted on the inner wall of the bearing seat plate by screws.

[0010] The movable arc cavities are located on the inner walls of both sides of the curved frame, and the interior of each movable arc cavity is equipped with an inner roller. A support rod is provided between the two inner rollers, and the two inner rollers are rotatably connected to the two ends of the support rod through bearings and connecting shafts.

[0011] An electromagnet is fixed to the inner wall of the movable arc cavity by a nail-free adhesive, and a power distribution box is set at the center of the base platform, with a power switch on one side of the power distribution box.

[0012] Preferably, each of the two support rods is provided with a support connecting rod at its upper end, and the two ends of the four support connecting rods are welded to the support rod and the movable arc table, respectively.

[0013] Preferably, mounting rods are welded to the outer walls of both ends of the bearing seat plate, and one end of each mounting rod is welded to the support frame.

[0014] Preferably, the piston rod of the first cylinder passes through a through hole inside the support frame and extends to the outside of the support frame, and the piston rod of the second cylinder passes through a through hole inside the movable carrier and extends to the bottom of the movable carrier.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention utilizes the movable connection between the inner roller and the movable arc cavity, allowing the movable arc platform to support the welding machine and spot welding gun in curved motion. This allows for welding at corresponding positions along the curved structure of the pipe segment stirrups. After moving to the designated welding position, pressing the power switch supplies power to the electromagnet in the distribution box, attracting and fixing the inner roller. This positions the movable arc platform at any location on the curved frame. During welding, the spot welding gun is adjusted laterally using the first cylinder and vertically using the second cylinder. This allows the spot welding gun to easily weld at any position on the pipe segment stirrups, overcoming the problem that existing automatic welding devices, while reducing safety hazards through baffles and protective frames, cannot adapt to the curved structure of the stirrups during welding, making pipe segment stirrup welding inconvenient.
