Abstract

PURPOSE:To improve the loading efficiency and the operation convenience by designing the truck shape to be of cab over type, presetting the width of the truck and the roof to be within the specified range of the railroad vehicles, and mounting the stay to fit a side mirror in a flexible and rotatable manner. CONSTITUTION:The shape of a truck 2 is of the cab over type, and the truck width W is the maximum width where the truck can safely travel on the railroad track. The dimensions a, b, c of a roof 11 are set in the specified range for the railroad vehicles, and the roof is formed in the shape of the Quonset hut. A stay 101 where a side mirror 12 is fitted is turnable in the direction of the arrow (d) around the supporting point 102, and flexible in the direction of the arrow (e), and can be inserted into the body in a retreative manner. This constitution provides the truck for piggy back transportation system with good loading efficiency.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a piggyback transportation system truck used in a piggyback transportation system for transporting a truck carrying a load together with the truck.

[0002]

2. Description of the Related Art First, the difference between a container transportation system and a piggyback transportation system will be described with reference to FIG. FIG. 4A shows a container transportation system, and FIG.
(B) is a diagram for explaining the piggyback transportation system, in which 1 is a freight car, 2 is a truck, 3 is a loading lamp, and 4 is a crossover. Container transport systems are well known and will not be described here, but this system requires containers. Due to the need to transship containers from trucks to freight cars, a considerable amount of space is required within the station premises at both the departure station and the arrival station. Forklift work for transshipment requires time and manpower. There are drawbacks such as.

The piggyback transportation system is a system devised to eliminate these drawbacks and has been in operation since November 1986. As shown in FIG. 4 (B), the truck itself loaded with the cargo is It is a system that transports the cargo on a freight car and transports the cargo together with the truck. It does not require a container as compared with a container transportation system. There is no need for space such as container storage. Since there is no need for container loading and unloading, there is no need for forklift work, and no space for that. The working hours of truck drivers can be shortened. It is possible to cope with labor shortages and exhaust gas regulations. There are merits such as.

[0004]

As described above, the piggyback transportation system has many advantages over the container transportation system, but this system has the following problems. In other words, rail transportation is subject to various restrictions due to the railway operation law and actual driving, but there are restrictions on vehicle height and vehicle width, and these restrictions are naturally imposed on piggyback transportation systems. . In particular, since the piggyback transportation system carries the truck itself loaded with the cargo, when the conventional freight car and truck are used, the vehicle height at which the vehicle can be operated is exceeded. In addition, since the truck itself can be loaded, the loading efficiency deteriorates, but in the current situation of overcrowded train schedules, it is very difficult to expand the transportation frame.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a truck for a piggyback transportation system which has a high loading efficiency and is easy to use even under the current size restrictions.

[0006]

The piggyback transportation truck according to the present invention is a so-called cab-over type truck, which enhances loading efficiency and has a vehicle width that is the maximum width that can safely travel on a railroad track, It is characterized in that it is provided with a means for forming a so-called semi-cylindrical shape defined by a railroad vehicle, and means for attaching a side mirror to a stay that can be expanded and contracted in the body and can be rotated.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the external shape of a truck that is an embodiment of the present invention. The upper diagram is a lateral view and the lower diagram is a rear view. In FIG. 1, 11 is a roof and 12 is a side. It's a mirror. As shown in the figure, the width (W) of this truck is the maximum width that can safely travel on the railroad track,
As shown in the figure below, the dimensions, (a), (b), and (c) are defined, respectively, and the shape of the roof is a semi-cylindrical shape within the range specified by the railway vehicle. With such a shape, when mounted on a freight car for piggyback transportation system according to the same application as the applicant of the present application and transported, the vehicle width (W) and the shape of the roof 11 can be safely traveled. It is possible to have a shape that ensures the maximum volume.

2 and 3 are views for explaining the structure and operation of the side mirror of the truck in this embodiment. In the figures, 100 is a front panel, 101 is a stay, and 102 is a stay 101 front panel. The stay 101 is configured to be rotatable about the fulcrum 102 in the arrow (d) direction and extendable and contractable in the arrow (e) direction. Reference numeral 103 denotes a support frame provided with a horizontally long moving hole for rotating and extending the stay 101,
An elastic material such as rubber is used for the support frame 103 from the vibration-proof surface. Fig. 4 shows the piggyback transportation system.
As shown in (B), a plurality of trucks 2 are mounted on the wagon 1.
Are arranged vertically and transported. Therefore, in order to improve the loading efficiency, it is necessary to reduce the space between the trucks as much as possible. By making the shape of the entire track 2 a so-called cab-over shape, it is possible to close the gap between the tracks, but the side mirror becomes a problem here. This is because the side mirror must be projected to the outside of the vehicle body when used for the purpose of its use.

For this purpose, the present invention is simple in that the side mirror can be inserted into the body to be expanded and contracted and the contact portion with the front panel 100 can be attached to the rotatable stay 101 as the fulcrum 102. By doing so, it is possible to keep the side mirrors out of the way when the freight car is installed. The structure for expanding and contracting and rotating the side mirror is not limited to the structure shown in FIG. 3, and may be automatically performed by driving a motor or the like.

[0010]

EFFECTS OF THE INVENTION The present invention has an effect that a truck capable of realizing an efficient piggyback transportation system can be obtained by adopting the structure described above.
