s5, extruding liquid 210 in an extruding groove 208 extrudes an extruding plate 207, the extruding plate 207 drives a correcting plate 204 to slide through a universal ball rod 206 until the correcting plate 204 is contacted with the inward bent channel steel and generates extruding force towards the inward bent channel steel for correcting and repairing the inward bent channel steel;

s6, meanwhile, the extrusion liquid 210 in the extrusion groove 208 continuously enters the elastic piece 301, so that the elastic piece 301 expands, the expanded elastic piece 301 generates extrusion acting force on the correction plate 204, and the extrusion effect of the correction plate 204 on the inward bent channel steel can be further improved;

s7, in addition, through the matched arrangement of the universal ball sleeve 205 and the universal ball rod 206, the correcting plate 204 can be in full contact with the surface of the inward bent channel steel, and the correcting and repairing effect of the correcting plate 204 on the inward bent channel steel is greatly improved, wherein the flow speed of the upper third control valve 303 is greater than that of the lower third control valve 303, so that the correcting plate 204 can be changed from an inclined state to a horizontal state, and the correcting and repairing effect on the inward bent channel steel is enhanced;

s8, when the level gauge monitors that the correcting plate 204 is horizontal, immediately closing the third control valve 303 and stopping the operation of the extraction pump 211, wherein at the moment, the correcting plate 204 and the correcting block 201 become the initial state again, and meanwhile, correcting and repairing the inward bent channel steel are completed;

s9, if the channel steel is bent outwards, the mounting plate 401 controls the connecting rod 403 to reciprocate, namely the hammering plate 404 on the connecting rod 403 can hammer the channel steel bent outwards in a reciprocating mode until the channel steel is corrected and repaired.

According to the technical scheme, the invention has the following beneficial effects:

according to the invention, through the arrangement of the channel steel correction device, the correction and repair efficiency of the deformed channel steel can be improved, the labor intensity of workers is reduced, the correction and repair precision and repair effect of the deformed channel steel can be improved, the potential safety hazard of the deformed channel steel can be greatly reduced, and the safe use of the deformed channel steel is ensured.
