Description

Technical Field

[0001] This utility model relates to the field of welding slag cleaning technology, specifically to a device for cleaning welding slag inside a bridge steel structure plate unit. Background Technology

[0002] In the welding of U-rib plate units in bridge steel structures, it is generally required that the U-rib and the steel plate undergo both external welding and internal welding. After the U-rib is internally welded, the weld slag is difficult to remove because it is located inside the U-rib.

[0003] Currently, most methods for cleaning welding slag generated from internal welding of bridge steel structure U-rib plate units involve using an overhead crane to lift one end of the U-rib plate unit, keeping it tilted, and then allowing the welding slag inside the U-rib to slide out along the tilt direction. Although this cleaning method can remove welding slag, it still has some problems: (1) It requires the use of an overhead crane to lift the U-rib plate unit, and the welded U-rib plate unit weighs tens of tons. When lifting the U-rib plate unit using flexible connecting cables, it is unstable and prone to tipping and falling, causing production accidents; (2) The welding slag inside the U-rib plate unit is not thoroughly cleaned. Therefore, it is urgent to develop a new type of welding slag cleaning device for bridge steel structure plate units to solve the problems existing in the current technology. Utility Model Content

The clamping from both sides by several fastening clamps prevents falling, thus allowing the welding slag on the inner wall of the U-shaped rib of the bridge steel structure plate unit to slide more safely and stably into the receiving groove. By installing several vibration generators at the bottom of the unit support plate, the unit support plate can be vibrated, and the vibration force can be transmitted to the bridge steel structure plate unit, causing the welding slag on the inner wall to vibrate and detach, improving the cleaning effect of the welding slag.
