Description

Technical Field

[0001] The utility model relates to the technical field of railway line signs, in particular to a railway line sign carving device. Background Art

[0002] Railway line signs refer to signs indicating the status or location of railway buildings and equipment, as well as the boundaries of management agencies at all levels of the line, including kilometer marks, half-kilometer marks, curve marks, the start and end points of circular curves and transition curves, bridge number marks, slope marks, and boundary marks of railway bureaus, engineering sections, leading work areas, road maintenance areas, and power sections. Railway line signs are mostly made of stone tablets, and general railway line signs are engraved on stone tablets using handheld engraving machines;

[0003] In the prior art, the Chinese utility model with publication number: CN216579911U discloses an intelligent engraving device for railway line signs, including a support platform and a first column fixed to the four corners of the upper surface of the support platform, the top of the first column is fixedly connected to a fixed frame, the left inner wall and the right inner wall of the fixed frame are slidably connected to sliding blocks, and the inner side of the sliding block is fixedly connected to two groups of sliding rods. The intelligent engraving device for railway line signs is used in conjunction with a lifting rod, a first spring, a card block, a rotating groove and a vertical groove. The user can adjust the grinding height of the engraving head through the lifting rod, and lock the card block with the rotating groove by rotating the handle, thereby locking the height of the engraving head. When the card block is aligned with the vertical groove, the lock is released, so that the device can fix the engraving depth of the engraving head, improve the stability of grinding, and the device can engrave stone tablets of different thicknesses;
