Steel structure bridge box welding positioning device

Abstract

The invention discloses a steel structure bridge box welding positioning device which comprises a rectangular positioning plate arranged in the welding seam extending direction, a rotating shaft is connected to one end of the positioning plate in the length direction, and a movable baffle capable of rotating around the rotating shaft is arranged on the rotating shaft in a sleeving manner and comprises a first baffle and a second baffle. The first baffle and the second baffle are in an L shape, a limiting block is arranged in an L-shaped cavity in the length direction of the positioning plate,the rotating shaft is located at the joint of the first baffle and the second baffle, the movable baffle is parallel to the ground, a return fixing rod is arranged at the end, away from the rotating shaft, of the positioning plate in the length direction, and a return spring is connected between the return fixing rod and the movable baffle. When a welding machine moves along a welding seam, the movable baffle is pushed to rotate, after the welding machine passes through the movable baffle, the rotated movable baffle automatically resets under the action of the spring, and the welding accuracyand the welding seam quality can be effectively improved.

Description

technical field [0001] The invention relates to the field, in particular to a steel structure bridge box welding positioning device. Background technique [0002] The code plate of the steel structure bridge is an indispensable auxiliary tool for the on-site processing of the steel bridge. The code plate fixes the position of two adjacent beam sections to be welded, fits the plane line shape of the bridge, and positions the beam section on site before welding. When domestic production units process steel structure bridges, the code boards are generally processed from waste materials, fixed and fully welded between two adjacent boxes, and carbon dioxide gas shielded welding is used to weld the two adjacent boxes. Remove the code plate and grind the surface of the box body. This method is time-consuming and material-intensive. Moreover, when welding with a carbon dioxide gas welding device, it is easy to cause problems such as spatter and poor forming, resulting in unstable we...

When domestic production units process steel structure bridges, the code boards are generally processed from waste materials, fixed and fully welded between two adjacent boxes, and carbon dioxide gas shielded welding is used to weld the two adjacent boxes. Remove the code plate and grind the surface of the box body. This method is time-consuming and material-intensive. Moreover, when welding with a carbon dioxide gas welding device, it is easy to cause problems such as spatter and poor forming, resulting in unstable welding quality and greater environmental impact.
