Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a loading platform for trucks, trailers and the like for transporting automobiles, which allows medium-sized trucks and small trucks to be stacked on top of each other to increase loading efficiency and to have two stages. It was developed with the purpose of enabling the loading of passenger cars.

<Prior Art> There are various examples in which a luggage carrier has a special structure in order to carry many automobiles on the luggage carrier at one time. The inventor of the present invention has also made many proposals so far, and patent No. 1023653 (Japanese Patent Publication No.
No. 333) and No. 1058096 (Japanese Patent Publication No. 55-46890) have already been patented.

The general structure of the loading platform for automobiles so far is, as seen in the above-mentioned publication and Japanese Patent Laid-Open No. 59-158681, the framed lower floor and the upper floor above it are framed by a frame structure, etc. The number of vehicles was increased by utilizing the loading space due to complicated movements such as making some parts turnable to form an inclined floor.

<Problems to be Solved by the Invention> Many of the loading platforms for automobiles that have been proposed so far are not limited to the above examples, but because of the focus on the effective use of the loading space, Since there was a relationship in which the rotation of the vehicle was the main means of solving, it was designed in consideration of a specific vehicle shape, lacked universality, and the movement when loading the vehicle was complicated. Therefore, although measures are taken such as scratching the car due to operation mistakes and changing the fixed position of the wheels partially if the type of car to be loaded is different, a structure with infinitely large tolerance In some cases, the number of loaded vehicles may decrease and the transportation efficiency may decrease.

<Means for Solving Problems> Therefore, according to the present invention, a plurality of divided lift floors (2a) to (2n) each having a large number of divided floor surfaces are arranged on a lower floor (1) which is significantly different from the conventional structure. Lifting device (3a) ~
(3n) is provided, and guide rails (4) and (4) are provided on both sides in the front-rear direction near the rising positions of the divided lifting floors (2a) to (2n).
An elevating floor which is provided with a plurality of movable supporting frames (5a) to (5m) so as to be movable back and forth, and which is lifted to the movable supporting frames (5a) to (5m) from a rising position of the divided elevating floor. We have developed an automobile loading platform having a structure with (7a) to (7m).

<Operation> The loading platform for loading an automobile having such a structure includes a lifting device (3a) provided with divided lifting floors (2a) to (2n), respectively.
When lowered by (3n) or raised to an appropriate position and aligned, the upper portion forms the lower or upper floor surface on which the vehicle can travel. Further, when the front wheels of the loaded vehicle are supported higher by the lifting floor (7) of the moving support frame (5) and the rear wheels are supported with the split lifting floor (2) in a lower position, the loaded vehicle is supported in an inclined state. . At this time, the movable support frame (5) allows front and rear wheels to be mounted on the movable support frame (5) to drive on the upper floor surface by driving rear wheels, thereby allowing the loaded vehicle to move and adjust to an arbitrary position by itself. Further, all the wheels of the upper loading of the automobile are supported high to the upper deck position by the lifting floor (7), and the divided lifting floors (2a) to (2n) are set to the lower floor (1) position to that part. When cars are loaded, they are stacked in two layers. By these actions, it is possible to take an arbitrary stacked state such as horizontal, inclined, and even two stages.

<Example> An example of the present invention will be described in detail below with reference to the drawings.
