Description

Technical Field

The bridge piers will not be fixed during cutting, resulting in unstable cutting. Utility Model Content

[0009] Through the operation of the reciprocating motor, the reciprocating motor synchronously drives the reciprocating screw to rotate, and the reciprocating screw synchronously drives the mounting plate sleeved above it to move, and the mounting plate then slides on the sliding block. At the same time, as the mounting plate moves, the mounting plate synchronously drives the laser cutter connected to it to move synchronously, and the laser cutter synchronously drives the laser cutting head connected below it to move horizontally, thereby cutting the bridge pier clamped by the clamping mechanism.

[0010] As a further improvement of the above solution, the moving mechanism includes:
