Abstract

PURPOSE:To improve loading and transporting efficiencies by providing a cab- over type of a truck with semicylindrical roof and forming only the pivotal part and peripheral part of a coupler for air pipe on freight cars out of a soft hose and mounting in free combination differently sized trucks on the freight car. CONSTITUTION:A position of mounting a coupler 12 on a freight car is lowered. Three spots, i.e., the pivotal parts X, Z of the coupler and the periphery of the connection Y are separately formed of soft hoses 101 so that a low floor is formed by minimizing the loosened length of the soft hose. The width of truck is maximized to allow the truck to travel safely on a rail road track and the roof is made semi-cylindrical to extensibly draw a side mirror into a body. Thus three 4t cars 2 can be mounted on the freight car and the respective dimensions of the length, width and height of the truck are checked to combine a 10t truck 20 with the 4t truck and ensure the inner volume. A truck is developed which can mount a 10t truck 20 or two 10t tracks 20 thereon within the effective loading range.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to 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 transfer containers from trucks to freight cars, it is necessary to secure a considerable amount of space within the station premises at both the departure station and the arrival station. Forklift work for transshipment takes 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 the conventional system has a problem that the transportation efficiency is poor. For example, a Koki car (container) and a Kum car (piggyback) with almost the same floor area
When the Comparing with one minute each wagons, in the case of Koki car (5 5t container ×) 25t in weight, the volume of 90m ³
(18m ³ × 5 pieces) can be loaded, but in the case of a Kumu car, the weight is 16t (4t loading truck 1t 8t ×
2 units) and the capacity is only 56 m ³ (28 m ³ × 2 units), and the loading efficiency is poor. In order to improve transportation efficiency under such circumstances, it is conceivable to increase the number of trains by overcrowding the timetables, but under the current overcrowded train timetables, it is very difficult to expand the transportation frame, And it will not be easy in the future.

To improve the loading efficiency of one freight car, simply speaking, a truck with a good loading efficiency and a freight car with a large loading capacity can be used, but it is possible to safely travel on the existing railway track without any hindrance. Moreover, in order to obtain an efficient system, it is not possible to simply change the dimensions of existing trucks and freight cars.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a piggyback transportation system which enhances the loading efficiency for one freight car and improves the transportation efficiency.

Means for Solving the Problems The applicant of the present application has a patent application “Piggyback transportation system truck” (hereinafter referred to as “first same-day application”), which is filed on the same date as the present application, and which meets the purpose of the present system. In the patent application “Piggyback transportation system freight car” (hereinafter, referred to as a second filing application on the same day), which was also filed on the same day, a freight car structure that meets the purpose of this system was developed. The piggyback transportation system according to the present invention is a system that uses trucks of different sizes (4t loading and 10t loading) having the above-mentioned structure and a freight car having the above-mentioned structure, and transports them in various combinations. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram for explaining the above-mentioned first application on the same day, and a detailed description thereof is explained in the first application on the same day, and a duplicate description will be omitted here, but even if a truck is loaded, its height is increased. 2 has a structure as shown in FIG. 2 in order to lower the floor so that it can operate on the railroad track without any hindrance, and to attach the connecting portion as low as possible in order to facilitate loading of the truck. That is, the mounting position of the coupler 12 is lowered, and the adverse effect due to the loosening of the air pipes such as the MR pipe and the BP pipe caused by this (when it is grounded or when it bends in a curve or the like, it greatly protrudes laterally and becomes an obstacle. In order to prevent this, a flexible hose is used to separately form three parts around the connector rotating part (indicated by X and Z in the drawing) that is a movable part and the periphery of the connecting part (indicated by Y in the drawing). In addition, by arranging these air pipes in the center of the vehicle body in the vicinity of the connecting portion, it is possible to minimize the required slack length of the soft hose. Therefore, it is possible to obtain a freight car with a low floor and a low attachment position of the connecting portion even if the vehicle body length is increased.

FIG. 3 is a diagram for explaining the above-mentioned second application on the same day, and the detailed description thereof is explained in the second application on the same day, and the duplicated description is omitted here, but the shape thereof is omitted. A so-called cab-over type that enhances loading efficiency, the width of the car is set to the maximum width that can safely travel on the railroad track, and the shape of the roof is the so-called kamaboko shape defined by the railroad car, and the side mirrors are inside the body. By attaching to a stay that can be expanded and contracted and can be rotated, when loading on a freight car, the mirror can be closely attached to the inclined part of the front of the body so that it can be efficiently arranged vertically on the freight car without disturbing protrusions. The structure of the truck allows

The system of the present invention uses a plurality of trucks and freight cars of different sizes (4t loading and 10t loading) and the freight wagon of the structure described above, and by combining these in various ways, the conventional system is An efficient system that could not be obtained was constructed. In the concrete system of the present embodiment, as shown in FIG. 1, the truck is integrated with the driver's seat and the body to increase the volume, and the length is shortened. A cube will be used rather than the conventional one so that three 4t cars can be loaded on top, and the space on the freight car will be effectively utilized. By utilizing this 4t truck and adapting it to diversified piggyback transportation by combining it with a 10t truck, the length, width and height dimensions of the truck are reviewed,
Secure the internal volume. Develop a truck for loading one truck in the effective loading range of a freight car. Develop a truck for loading two trucks in the effective loading range of a freight car. We have improved the system to make it more meaningful.
