Background technique

H-beam is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter "H". The production of modern H-beam generally requires two steps of spot welding and full welding. Among them, spot welding refers to the initial fixing of a web and two wings by spot welding. In order to complete the spot welding of H-beam, the H-beam needs to be pre-assembled during spot welding.

At present, pre-assembly is mainly performed by manual positioning and spot welding with the driving, that is, during spot welding, the flange plate needs to be turned over and the web plate is lifted to form a prototype of H-beam. However, since the length and weight of the steel plate are very large, it is particularly difficult to turn it over and lift it up. Using driving for auxiliary operation not only has low work efficiency, but also has poor safety and is prone to accidents.
