[0023] A steel structure processing and grinding equipment includes a workbench 1, on which a group of side panels 2 and vertical panels 3 are fixedly arranged, the group of side panels 2 are symmetrically arranged on the table top of the workbench 1, and a group of guide grooves 15 are arranged on the inner walls of the group of side panels 2, the vertical panels 3 are vertically arranged to the group of side panels 2, a first telescopic rod 4 is arranged on the vertical panels 3, the first telescopic rod 4 is fixedly arranged on the inner walls of the vertical panels 3, a hydraulic cylinder 19 is arranged on the outer walls of the vertical panels 3, the first telescopic rod 4 is arranged at the output end of the hydraulic cylinder 19, and a push plate 5 is arranged at the telescopic end of the first telescopic rod 4, which can slide inside the group of guide grooves 15 to push the steel structure to move.

[0024] Place the steel strip on the table of the workbench 1, between the push plate 5 and the connecting frame 11, start the hydraulic cylinder 19, so that the first telescopic rod 4 drives the push plate 5 to approach the side of the steel strip, and pushes the steel strip to move along the direction of the guide groove 15 until it moves to the top of the groove 13 for initial grinding.

[0025] A top plate 9 is fixedly arranged between a group of side plates 2, and the top plate 9 is arranged between the side plates 2 above the groove 13. A hydraulic cylinder 19 is arranged on the top wall of the top plate 9, and a second telescopic rod 10 is arranged at the bottom of the top plate 9.
