A pull-cord 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 a material pile, the steel wire rope is tensioned, and the ground anchor switches perform limiting actions so as to send an impact signal; however, the cantilever of the stacker-reclaimer is long, generally ranges from 20 meters to 60 meters, the steel wire rope generates a drooping arc line due to the gravity of the steel wire rope and cannot be in a completely tensioned state, when the cantilever impacts a material pile, the shape of the steel wire rope is changed by the extrusion of the material pile from a drooping section, 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, particularly in the stacker-reclaimer with the cantilever length of more than 40 meters, because the drop section of the steel wire rope is long, the material pile already collides with the cantilever steel structure before the action of opening and closing the ground anchor, and the protection effect is not achieved. And laser scanner collision avoidance uses the import brand to give first place to at present, and the price is very high, and in addition, dust concentration is very big in the bulk cargo stock ground, and the material powder can glue laser emission device on, thereby leads to scanner inefficacy can't realize collision avoidance.
