2. Description of the Related Art Conventionally, as a vehicle carrier of this type, a pair of left and right slat conveyors for supporting and carrying a vehicle through wheels are provided as shown in Japanese Patent Laid-Open No. 19611/1985. A configuration is provided in which a shuttle conveyor is provided between the conveyors, and two shuttle-supportable load supports are provided at predetermined intervals. Each load support base is provided with a fixed support and a movable support that can approach and separate from the fixed support.

According to this conventional type, the vehicle is lifted from the slat conveyor by bringing both supports raised together with the load support table into contact with the lower surface of the vehicle body conveyed by the slat conveyor, and then the shuttle conveyor. Is carried by a predetermined pitch. Furthermore, the movable support is moved closer to and separated from the fixed support to cope with a plurality of vehicle types.

However, according to the above-mentioned conventional type, by causing both the support members to act on the lower surface of the vehicle body of the vehicle, problems such as damage to the supported portion on the lower surface of the vehicle body easily occur depending on the weight of the vehicle. Further, the supported portion has various shapes and sizes, and in order to appropriately touch these, it is necessary to prepare and replace many kinds of supporting tools.

As a means for solving such a problem,
For example, it is conceivable to adopt the vehicle transfer device shown in Japanese Utility Model Publication No. 55-167921. That is, the lifting mechanism includes a pair of front and rear movable arms that are horizontally rotatable on both left and right sides, and a pair of front and rear motors and worm mechanisms that synchronously horizontally rotate the left and right movable arms. In this other conventional configuration, the pair of front and rear movable arms are pivoted in parallel to support the vehicle via the wheels.

[0006]

According to the above-mentioned another conventional type, since both movable arms forming a pair in the front and rear are rotated by the electric motor and the worm mechanism of different systems respectively, the rotation of both movable arms. Is likely to be misaligned, and as a result, the vehicle is supported with its posture disturbed, and even a slight disturbance of posture makes it impossible to perform various post-work accurately.

An object of the present invention is to provide a vehicle carrying device capable of opening and closing a pair of front and rear swinging rods for supporting wheels without opening and closing of timing, and locking both open and closed positions. There is a point to do.

[0008]

In order to achieve the above object, a vehicle carrier of the present invention is provided with a front wheel supporting device and a rear wheel supporting device on a movable body which is movable on a carrier path, and at least these supporting devices. A first actuating device is provided that allows one to move toward and away from the other
Each of the supporting devices is composed of a pair of front and rear rocking rods that support the wheels by closing motion and support and open by opening motion, and a second actuating device that opens and closes these rocking rods. A position locking mechanism is provided.

[0009]

According to the structure of the present invention, the movable body is mounted on the vehicle so that the front wheel support device faces the front wheel and the rear wheel support device faces the rear wheel in a state where the swing rods of both support devices are opened. Correspond. Then, the front and rear rocking rods are swung toward each other by the operation of the second actuating device to support the wheels. Alternatively, the wheels are placed on and supported by the support device by lowering the vehicle with the lifter device while the swinging rods are swung toward each other.

At this time, since the front and rear rocking rods form a pair and are synchronously closed by the second actuating device, the timings of the closing movements can be performed without deviation, and the wheels can act almost simultaneously. As a result, the vehicle can be lifted through the wheels without disturbing the posture.

After supporting the vehicle in this manner, the vehicle can be transported by moving the moving body to the lower side. Then, after the vehicle has been transferred to a predetermined location, the support of the wheels is released by swinging the swing rods away from each other by the reverse operation of the second actuator.

When a vehicle of a different type flows, the first actuating device operates to move at least one of the front wheel supporting device and the rear wheel supporting device toward or away from each other, so that both supporting devices are moved. The distance between can be adjusted to the wheelbase of the corresponding vehicle.
