Description

Technical Field

[0001] The utility model relates to the field of supporting devices, in particular to an auxiliary supporting device for welding connecting gaps of crane beams. Background Art

[0002] Crane beams undertake the critical task of lifting heavy objects in industrial buildings and other places. If the connection gaps are not properly handled, it may affect the stability of the overall structure. Therefore, the connection gaps are generally handled in a reliable way such as welding. Welding can firmly connect the components on both sides of the gap to form a whole, effectively resisting the effects of various external forces, thereby ensuring the safety and stability of the crane beam when lifting heavy objects.

[0003] However, when welding the joints of crane beams, workers typically weld steel bars into spoon-shaped racks, then hang the racks on the crane beams. Workers stand on the racks to weld the joints on the outside of the crane beams. This method has obvious drawbacks. First, workers stand on the homemade spoon-shaped racks to weld at high altitudes, posing a significant threat to their own safety. Second, these welded racks are bulky and irregularly shaped, making them difficult to carry around. This creates significant inconvenience when moving between different work locations, impacting work efficiency and flexibility. Utility Model Content
