Lift-up device of traffic cone collecting and placing device

According to the lifting device of the traffic cone collecting and releasing device, an inner supporting pipe is connected to each corner of a regular hexagon connecting plate in a welded mode, a top plate is arranged at the upper ends of the six inner supporting pipes to form a regular hexagonal prism shape, and an end socket is arranged on the upper surface of the top plate. Due to the fact that the six inner supporting pipes are adopted to manufacture the six-prism-shaped traffic cone lifting device, when the six-prism-shaped traffic cone lifting device enters the cone shape of a traffic cone, the outer surfaces of the six inner supporting pipes are in linear contact with the inner surface of the traffic cone, friction force between the inner supporting pipes and the inner surface of the traffic cone is reduced, and the traffic cone lifting device is convenient to use. And the phenomenon of clamping stagnation when the device is separated from the traffic cone due to overlarge friction force is prevented.
