VEHICLE LIFT DEVICE, PARALLEL UNMANNED TRAVELING VEHICLE, TRANSPORT VEHICLE, VEHICLE PARALLEL PARKING SYSTEM, AND VEHICLE PARALLEL PARKING METHOD

摘要

To provide a vehicle lift device, a parallel unmanned traveling vehicle, a transport vehicle, a vehicle parallel parking system, and a vehicle parallel parking method which can be configured to be as simple as possible and can move a vehicle up and down by using a small volume of actuators.SOLUTION: The device comprises a pair of arm portions 11 which support a tire 3A by being in contact with the front and rear sides of the contact portion of the tire 3A respectively in the supported state, each of which comprises a rod having a length about the width of the tire, a pair of rotating support portions 13 rotatably supporting the arm portion 11 at the base end portion about a longitudinal axis 12, a rotating cylinder 15 which rotates the arm portions 11 from the supported state by 90 degrees by the forward/backward driving of a rod 14 whose tip is connected to one of the rotating support portions 13 to the released state separated from the tire 3A, a rotation transmission gear 16 which converts the rotation of one rotation support portion to a reverse rotation and transmits the rotation to the other rotating support portions, and an elevating cylinder 17 which moves the arm portions vertically.SELECTED DRAWING: Figure 2
