Before the recycling of the waste metal, the recycled waste metal needs to be processed, such as cutting, crushing and the like, so as to be reused in a later period. When some waste metals with larger volumes are treated, the waste metals need to be cut by adopting a gantry shear. The gantry shear mainly comprises a discharging table, a gantry frame, a shear head and a hydraulic driving element, wherein the shear head is arranged on the inner side of the gantry frame in a lifting manner through a guide rail, when the shear head slides up and down for a long time, the guide rail is subjected to the extrusion force of the shear head for a long time, the gap between the shear head and the guide rail is easily caused to be too large, the stability of the subsequent sliding of the shear head can be affected, and therefore the risk of equipment failure is increased. The traditional way is that one side of the guide rail is provided with a fixed limiting block and an adjusting pressing bar, and the gap between the guide rail and the shear head is adjusted through the adjusting pressing bar, so that the overlarge gap between the guide rail and the shear head is avoided. However, the traditional adjusting pressing strip is of a segmented block structure, so that the guide rail is stressed unevenly to be bent; meanwhile, the traditional fixed limiting block is directly welded or mounted on the edge of the gantry frame by bolts, and is easy to burst and fall off.
Therefore, how to provide a limit adjusting mechanism for a cutting head of a gantry cutting machine is a research purpose of the utility model.
