The existing cantilever anti-collision protection device generally adopts a pull-switch type or a laser scanning type. The pull-rope switch type anti-collision device is characterized in that ground anchor switches are arranged at the front end and the rear end of a cantilever, the front switch and the rear switch are connected through a steel wire rope, when the cantilever collides with a material pile, the steel wire rope is tensioned, and the limit action of the ground anchor switches is performed, so that an impact signal is sent out; however, as the cantilever of the stacker-reclaimer is longer and is generally unequal at 20-60 meters, the steel wire rope generates a sagging arc line due to gravity and cannot be in a complete tensioning state, when the cantilever impacts a material pile, the sagging section of the steel wire rope is extruded by the material pile to change the shape, so that the deformation direction of the steel wire rope is changed from vertical downward bending to horizontal bending towards the cantilever direction, and the ground anchor switch is pulled after the horizontal direction is completely tightened; in many cases, especially in stacker-reclaimers with cantilever lengths above 40 meters, the pile is bumped into the cantilever steel structure before the ground anchor switch acts due to the longer sagging section of the steel wire rope, so that the pile cannot play a role in protection. But laser scanner anticollision protection, at present mainly takes the import brand, and the price is very high, and in addition, dust concentration in the bulk cargo stock ground is very big, and the material powder can glue on the laser emission device, thereby leads to the scanner inefficacy can't realize anticollision protection.
