A road cone recovery device for a traffic cone automatic retractable vehicle, including a clamp, the clamp includes a left outer splint, a right inner splint, a left inner splint, an inner splint wall, a hinge, a hydraulic cylinder, a microwave radar sensor, and the clamp and The first mandrel is connected with the U-shaped connecting arm, the U-shaped connecting arm is connected with the hydraulic telescopic arm, the hydraulic telescopic arm is connected with the second mandrel, and the gear surface at the end of the second mandrel is in contact with the gear surface of the stepping motor. When working, the microwave radar sensor senses the position of the traffic cone, the clamp fixes the traffic cone, the hydraulic telescopic arm shrinks to lift the traffic cone fixed by the clamp connected to the U-shaped connecting arm, and the stepping motor drives the hydraulic telescopic arm connected to the second mandrel to rotate , Transport the traffic cone to the designated location, the whole process does not require manual participation. A plurality of devices of the present invention are arranged outside the traffic cone automatic retractable vehicle to recover the traffic cones and improve work efficiency.
