Abstract

The invention relates to a combined rail freight transport system using a simple hydraulic system. The device is mounted on the rail bogies and on the trucks providing the combined rail freight transport. The hydraulic system consists of hydraulic lift cylinders (1), hydraulic pump (2), and hydraulic switch box with valves (3).

Description

Combined Transport in Rail Freight

Field of Technology

The invention relates to simplification, cheapening and acceleration in the rail freight transport. Acceleration of loading and unloading in the rail freight transport is achieved by using a simple hydraulic system.

Present Situation

Currently, loading and unloading of containers and swap bodies is done by heavy- load overhead travelling cranes. Locomotive moves the railway wagon under the crane rails. By means of crane the container or swap body is lifted from bogie and moved to the free space next to the rail tracks. Heavy-load forklifts move the load from the free space and put it either on a truck or in a free space of the terminal. The same process is used vice versa, i.e. from a truck onto the railway bogie. Trucks ensure transport to and from the terminal.

Summary of the Invention

The invention consists in the change of technology and the way of handling swap bodies and containers. Instead of heavy-load cranes the invention uses hydraulic device mounted on bogies. Instead of heavy-load forklifts hydraulic device is placed on trucks providing loading and unloading. Ramps are fitted with a facility where containers or swap bodies are temporarily placed. The advantage of the invention is also the fact that at the same time all containers and swap bodies can be unloaded from bogies onto the extended cylinders in ramps. Another advantage is that bogies can be moved into the station where the loading is performed. From an economic point of view its importance lies in the fact that bogies are expensive investments and by employing the invention bogies are maximally utilized with a minimum idle time. Minimum idle time shall be secured in such a way that the railway station, where the loading is performed, shall have a ramp for reserve swap bodies and containers and shall have the necessary number of swap bodies and containers. The ramp can be built at the station or in its vicinity. Combined transport in different gauges. In case of different track gauges we proceed similarly as in the transition from rail transport to road transport. In the new proposed solution ramps are built on both sides of the broad-gauge line in which hydraulic device is assembled. From the inside of the broad-gauge line rails shall be mounted so that wagons with a narrower gauge can go through. Thus we get dual parallel rails having two dimensions. A broad-gauge train with the equipment assembled on bogies reverses into the ramp area. The train is connected with a cable to the ramp s electrical power distribution. By means of the hydraulic device controlled by the main switch the swap bodies are lifted on the entire train. By means of the hydraulic device mounted in the ramps and controlled by the main switch, support cylinders are extended under the swap bodies. By means of the hydraulic device mounted on the bogies and controlled by the main switch, swap bodies are lowered onto the support cylinders. The cable is disconnected from the ramp^'s electric power distribution and the train can leave with its bogies without swap bodies. From the other, narrow-gauge side, the train reverses with its bogies under the swap bodies, with a cable the train is connected to the ramp's electrical power distribution and by means of the hydraulic device mounted on the bogies and controlled by the main switch, the swap bodies are lifted. By means of the hydraulic device mounted in the ramp and controlled by the main switch, support cylinders are extended into the ramp area. By means of the hydraulic device mounted on the bogies and controlled by the main switch, swap bodies are lowered onto the bogies, the cable is disconnected from the ramp's electrical power distribution and the train with the swap bodies can leave. The same transshipment can also start from the opposite side.

Clarification of Drawings

Drawings provide details of the technical solution of the invention.

Figure 1 schematically illustrates the rail wagon bogie frame and the truck chassis frame. Frame reinforcement with U-profile 4, extension of the surface with angle profile 5, for mounting hydraulic cylinders 1 Placement of hydraulic pump 2, placement of hydraulic switch box with valves 3. Hydraulic lift cylinders are placed mainly according to the construction of the wagon bogie or truck chassis onto which the lift cylinders will be mounted. In doing so, it will be important to maintain stability and arrangement of cylinders as shown in the Figure L Hydraulic lift cylinders will be engaged as follows. When lifting individually, three containers or swap bodies placed on a single bogie with dimensions of 1/3 of the bogie we lift with valves connected to the circuit of four lift cylinders. When lifting individually, two containers of swap bodies placed on a single bogie with dimensions of 1/2 of the bogie we lift with valves connected to the circuit of six lift cylinders. When lifting one container of swap body placed on a single bogie with dimensions of the bogie we lift with valves connected to the circuit of twelve lift cylinders. As a rule, this valve is controlled electromagnetically in rail bogies and mechanically in trucks.

The ramp at the customer is the same as shown in Figures 2,3,4. It can be implemented in connection with a building or storage where the transported goods need to be stored. The ramp will be equipped with hydraulic device.

The ramp will be constructed according to Figures 2,3,4 with an emphasis on Figure 4. The ramp will be equipped with hydraulic device.

Ramp for reserve containers and swap bodies will be built in free space of the railway station or its vicinity on truck's both sides. The ramp must be accessible from both sides as on one side containers will be placed on swap bodies will be on the other. The ramp will be equipped with hydraulic device. The ramp will be built according to Figures 2,3,4.

Examples of Invention Embodiment

Transport of goods begins with the dispatcher. Customer orders transport of goods from point A to point B within the agreed time. The transport will be carried out as follows: the truck driver reverses to the ramp for . reserve swap bodies and containers under the swap body. By means of hydraulic device on the truck he lifts the swap body; by means of hydraulic device on the ramp he inserts the support cylinders into the ramp area. By means of hydraulic device on the truck he lowers the swap body onto the truck. The driver will take the swap body to the customer. At the customer's he reverses to the ramp area, by means of hydraulic device on the truck he lifts the swap body, by means of hydraulic device on the ramp he extends the support cylinders, by means of hydraulic device on the truck he lowers the swap body onto the support cylinders and he can leave with the truck. After loading the goods onto the swap body the driver reverses the track under the swap body and by means of hydraulic device on the truck he lifts the swap body. By means of hydraulic device on the ramp he inserts the support cylinders into the ramp area; by means of hydraulic device on the truck he lowers the swap body onto the truck. The truck driver will take the swap body to the loading station, reverses to the cargo ramp, by means of hydraulic device on the truck he lifts the swap body, and by means of hydraulic device oh the ramp he inserts the support cylinders under the swap body. By means of hydraulic device on the truck the swap body is lowered onto the support cylinders and the truck can leave. The locomotive reverses the rail wagon bogie to the cargo ramp under the swap body. The bogie is connected to the ramp's electric distribution by means of electric cable. By means of hydraulic device on the rail wagon bogie the swap body is lifted. By means of hydraulic device on the ramp the support cylinders are extended into the ramp area. By means of hydraulic device on the bogie the swap body is lowered onto the rail wagon bogie. Locomotive can move the wagon and attach it the freight train bound for unloading station.
