In order to realize the overturning of the steel beam, the technology adopted at present mainly comprises the steps of lifting or hanging the steel beam, respectively extending the two ends into the clamping mechanism nest, locking the steel beam from multiple directions, encircling the steel beam in the mechanism, and driving the steel beam to overturn. However, this method has the following problems:

firstly, the encircling clamping mechanism is relatively large, the operation difficulty of lifting or hoisting the steel beam and enabling two ends to extend into the clamping mechanism is high, the clamping mechanism is possibly knocked and damaged due to unstable hoisting, if manual participation is long, labor is consumed, potential safety hazards are caused, if automatic loading is adopted, the mechanism is relatively large, the operation is equivalent to that of using an unmanned crane and hanging ropes for releasing ropes, and two ends are required to be aligned and extend into the clamping mechanism respectively, so that the difficulty is high.

Secondly, after the two ends of the steel beam extend into the clamping mechanism, the steel beam is locked in the second step, the upper face, the lower face, the left face and the right face of the steel beam are fixed, the steel beam can be prevented from loosening, the workload is large, each end of the steel beam is provided with 3-4 locking devices, and a plurality of electric locking mechanisms synchronously operate, so that the steel beam is complex and has a large investment.

And thirdly, the locking force is not well grasped, the locking device is damaged if the locking force is too tight, the friction force is insufficient if the locking force is not tight, slipping and dislocation occur in the overturning process, and machining dislocation is caused.

In addition, when processing is completed, a plurality of sets of clamping devices are loosened, and the steel beam is hoisted or lifted out, so that the whole process is time-consuming and labor-consuming, low in efficiency and poor in safety.

Therefore, how to turn over large and heavy steel beams in a time-saving and labor-saving manner is a technical problem which needs to be solved at present.
