[0002] In municipal road and bridge construction, box girders are indispensable. In order to improve construction efficiency, the structural parts and internal reinforcement cages in the box girders are usually prefabricated. When processing the box girder bottom and web reinforcement cages, it is necessary to weld the arranged box girder bottom and web stirrups into three-in-one combined stirrups, weld the external longitudinal reinforcement on the outside of the combined stirrups, and weld the internal longitudinal reinforcement on the inside of the combined stirrups, so as to form the overall reinforcement cage of the box girder bottom and web.

[0032] The embodiment of the present invention provides a welding forming production equipment for beam stirrups, referring to Figure 1 and Figure 2, including a steel bar hoop bending machine 1, a steel bar placing machine 2 and a welding manipulator 6. A placing platform 11 with a horizontal top is connected to the discharging end of the steel bar hoop bending machine 1. The stirrups sent out from the steel bar hoop bending machine 1 and bent into shape are cut and placed horizontally on the placing platform 11. The stirrups on the placing platform 11 can be placed by the staff to form the required welding shape of the bottom and web stirrups. The steel bar placing machine 2 is used to position and clamp the bottom and web stirrups. The steel bar placing machine 2 includes a welding platform 21. The welding platform 21 is located on one side of the placing platform 11. The platform height of the welding platform 21 is consistent with the platform height of the placing platform 11. The welding platform 21 is provided with a placing mechanism 3 for aligning the web stirrups and the bottom plate stirrups.

[0033] The device of the present application includes a towing mechanism 4, which is used to clamp the web stirrups and the bottom plate stirrups on the placement platform 11, and tow the web stirrups and the bottom plate stirrups from the placement platform 11 to the welding platform 21. The welding manipulator 6 is arranged on one side of the welding platform 21, and a welding gun is installed at the movable end of the welding manipulator 6. The welding manipulator 6 moves the welding gun to the connection between the bottom plate stirrups and the web stirrups on the welding platform 21, and welds the bottom plate stirrups and the web stirrups, thereby welding and forming the bottom and web three-in-one stirrups.

[0034] Specifically, the placement mechanism 3 includes a plurality of first push plates 31 and a plurality of first finger cylinders 32 arranged on the welding platform 21. The first push plates 31 are at least distributed on the side of the three-in-one stirrups of the bottom plate stirrups and the web stirrups on the welding platform 21 away from the placement platform 11. When the dragging mechanism 4 drags the bottom plate stirrups and the web stirrups from the placement platform 11 to the welding platform 21, the bottom plate stirrups and the web stirrups abut against the first push plates 31, and the preliminary positioning of the bottom plate stirrups and the web stirrups can be achieved. At least one first clearance hole 22 is opened on the welding platform 21 directly below each bottom plate stirrup and web stirrup. The first finger cylinder 32 is located directly below the first clearance hole 22. A first driving member for driving the first finger cylinder 32 to rise and fall vertically is arranged in the welding platform 21.

In the embodiment of the present application, the pressure rod 35 and the second cylinder 37 are provided with two groups, which are respectively aligned with the overlapping parts of the web stirrups and the bottom plate stirrups. The pressure rod 35 is driven to rotate by the second cylinder 37, so that the pressure rod 35 can stably press the overlapping parts of the web stirrups and the bottom plate stirrups. The welding platform 21 is provided with a resisting block 38 for resisting the outer edge of the overlapping area of ​​the web stirrup and the bottom plate stirrup, and the clamping block 36 is directly opposite to the inner opening of the overlapping area of ​​the web stirrup and the bottom plate stirrup. The clamping block 36 is horizontally slidably arranged on the first lifting plate 33, and the first lifting plate 33 is provided with a third cylinder 39 for driving the clamping block 36 to slide close to / away from the resisting block 38. The resisting block 38 and the clamping block 36 are used to clamp the edge of the overlapping area of ​​the web stirrup and the bottom plate stirrup together, so that the web stirrup and the bottom plate stirrup can be kept vertically overlapped, and the structural stability of the three-in-one stirrup is ensured during the welding process.
