Description

Technical Field

[0001] The utility model belongs to the technical field of gantry shears, in particular to a highly stable and wear-resistant guiding mechanism for gantry shears. Background Art

[0002] The upper cutter head of the existing gantry shear equipment is connected to the gantry frame on both sides through a guide mechanism. In order to improve the wear resistance of the guide mechanism, a wear-resistant plate can be arranged on each connection surface between the upper cutter head and the gantry frame. The mutual friction between the two wear-resistant plates can improve stability and wear resistance.

[0003] After the gantry shearing equipment has been used for a certain period of time, the wear-resistant plate will still wear out, and the thickness will decrease after wear, which will affect the stability of the upper cutter head lifting and lowering, thereby affecting the stability of the entire machine and the shearing effect. If the wear-resistant plate is replaced directly, more parts need to be removed, which will cause problems such as difficult operation and low efficiency. Summary of the Invention
