Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a turntable-type automobile transporter that allows loading and unloading of automobiles onto freight cars one freight car at a time without using mechanical equipment such as a crane. It concerns freight cars.

Car transportation by rail is considered to be one of the future means of transportation for land-based car ferries. At sea, where road transport is impossible, if there were a railway undersea tunnel, better service could be provided by using so-called car trains, which take advantage of the high speed of railways and connect multiple freight cars for transporting cars, instead of car ferries. Even when it comes to transportation, long-distance transportation by automobile has its own problems in terms of energy and driver fatigue, so automobile transportation by rail is considered to be the most desirable because it is safe, quick, and energy-saving.

[Conventional technology and problems] In the conventional method of loading cars onto a train during car transport, a running ramp is placed at the end of the train where cars can board the train on their own, and from there the cars drive themselves one after another. The method was to board the train and fill it up one by one from the front of the train. In addition, when lowering a car, the locomotive in front was removed, a running ramp was placed in front, and the cars were lowered one by one from the front. With this method, it was practically impossible to unload cars mid-way because it would involve shunting trains.
Furthermore, since railways have restrictions on the height of the top of large trucks, they have developed low-floor freight cars with smaller wheels and a lower floor surface.
Even that had its limits.

[Means for solving problems]

The present invention has been made to solve these problems, and it makes it possible to load and unload automobiles on a single freight car basis, and also lowers the floor surface of the freight car by recessing the space between the bogies of the car body frame. This made it possible to carry large trucks. In other words, there is a car body frame which is lowered by recessing the upper surface of the frame between the bogies, and a two-piece frame which is movable up and down with hinges at both ends on the upper part of the low frame part of the car body frame.
A turntable with two running plates attached, a rotating device that applies rotational force to the turntable, and rollers for rotating the turntable at both ends of the low underframe, and the turntable rotates on the body underframe. Sometimes, support arms with rollers and support legs are provided to support the load, and the car can be loaded and unloaded one freight car at a time by self-propelled using a turntable from the running plate without using mechanical equipment such as a crane stand. It is.

〔Example〕

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is an overall explanatory view of the present invention, in which a vehicle body underframe C is mounted on two bogies B, with the upper surface of the underframe between the bogies being depressed to make it lower. Further, on the upper part of the lower frame portion of the vehicle body frame C, there is mounted a turntable E on which the automobile A is mounted, and two traveling plates E, which are movable up and down by hinges, are attached to both ends.

FIG. 2 is a plan view of the vehicle body underframe C, in which there is a rotating device R that applies rotational force to the turntable placed on the upper center portion, and rollers K for rotating the turntable at both ends of the lower underframe. Furthermore, a support arm S to support the load of the turntable when the turntable rotates is attached to the car body underframe C so that it can rotate horizontally with a hinge, and normally the support arm S is attached to the car body underframe C so that it can rotate horizontally.
However, before the turntable rotates, it is opened outward by an angle perpendicular to the rotation angle of the turntable. A roller K for rotating the turntable is also provided on the upper surface of the support arm S. FIG. 3 shows a turntable T mounted on the vehicle body frame C shown in FIG. A running plate E is attached to both ends of the turntable T. With the running plate E raised, the turntable T is rotated by the rotating device R to an angle that allows the running plate E to be lowered to the ground, and then the running plate E is lowered to the ground. .

FIG. 4 is a side view of FIG. 3, with running plates E lowered from both ends of the turntable T so that cars can be loaded and unloaded onto the ground. The load of the turntable T is supported by the support arm S.

Figure 5 is a side view of the support arm S and the turntable T.
The load is supported on one side by connecting the car body underframe C and the hinge H, and on the other side, the load is supported by the supporting foot F that has landed on the ground due to the action of the joint J.

〔Effect of the invention〕

As described above, the present invention has a turntable having a movable running plate mounted on the body frame of a freight car for transporting automobiles, and by rotating the turntable to change the direction of the turntable. It has the advantage of not only making it possible to load and unload onto freight cars by moving, but also making it possible to load large vehicles by lowering the body frame between the bogies.
