The invention discloses a beacon taking-back and placing mechanism for an intelligent snow sweeping robot. The beacon taking-back and placing mechanism for the intelligent snow sweeping robot comprises a mounting base plate, vertical guide rails, a sliding block, beacon taking-back and placing forks, a vertical lead screw, a stepping motor and a transmission device, wherein the sliding block is in sliding fit with the vertical guide rails, the beacon taking-back and placing forks are fixed to a connecting plate, the vertical lead screw is located between the two vertical guide rails, the stepping motor is fixed to the snow sweeping robot, and the transmission device is connected with a rotary shaft of the stepping motor and the vertical lead screw. The beacon taking-back and placing mechanism for the intelligent snow sweeping robot further comprises telescopic electromagnet sets and beacons. By adoption of the beacon taking-back and placing mechanism for the intelligent snow sweeping robot, automatic taking-back and placing of the beacons are achieved, and the front ends of insertion rods of the beacon taking-back and placing forks of the beacon taking-back and placing mechanism incline upwards and can make the beacons automatically slide back to original positions through gravity when the bacons are taken back, so that the beacons are taken back more easily; meanwhile, inverted-V-shaped grooves are matched with the beacon taking-up and placing forks, so that the beacons can be positioned conveniently when placed, and accordingly the beacon placing precision is improved easily and the beacon taking-back difficulty is lowered; and furthermore, the inverted-V-shaped grooves are matched with telescopic electromagnets so that the taken-back beacons can be accurately positioned and placed.
