Abstract

Described is a device for reducing time in transferring a container loaded on a railway boxcar into a road vehicle and vice versa. The inventive system known as "MACYR" is installed between a railway sub-line and a wide street for facilitating the access of road vehicles located outside the metropolitan area, then a railway loaded with containers and coming from a port, is diverted from the main line and stopped in the sub-line; the traction system of the railway is provided with fuel, lubricant, and water while the said railway is stopped, a general checking is also performed and the crewmembers are changed. The efficiency in transferring a load from the railway boxcar into the road vehicle will depend on the number of boxcars having containers, and will be directly related to the number of MACYR devices operating in site. When the railway is stopped, the MACYR system and two operators per each unit perform the following steps: For a container of 12.296 mm (40 feet) the MACYR system is brought into contact with a boxcar loaded with a container; a beam (spreder) is placed onto the container (the system may stack the discharged containers); the container cylinder is separated apart and the flukes of a fork lift are introduced into said cavity, finally pins located at the corners of the container are secured and the container is lift by the system. The cylinder is displaced to the opposite side and the aforesaid action is repeated, once the containers are loaded the cylinder is placed at the central portion of the beam rotating 180 degrees and discharging the container that was loaded in the road vehicle onto the railway boxcar. The beam (spreder) is removed and led to the opposite side, thus repeating the aforesaid action on the road vehicle. Containers that are less voluminous and lighter than those aforementioned are loaded by their lower portion following the same steps performed for containers of 12.296 mm (40 feet) without using the beam (spreder). A computing system would be required for optimising the operation of the MACYR system. The inventive system represents a leading-edge technology for railway systems.

Description

APPARATUS TO MINIMIZE THE MOVEMENT OF CONTAINERS LOADED IN RAILWAY WAGONS TO TRANSPORT TERRESTRIALS 1. FIELD OF THE INVENTION The present invention relates in general to an apparatus for facilitating the loading and unloading of containers in the railway system.

This device speeds up maneuvers, significantly increasing efficiency, and consequently will increase cargo handling by rail. 1. BACKGROUND OF THE INVENTION Railroads have been losing their presence in cargo handling due to the low efficiency with which they operate. The railroad gets its income when it moves cargo from one place to another in the shortest possible time. The time to transfer cargo from railway wagon containers to land transportation must be the minimum necessary.

The time of only a few minutes to transfer a container of rail to a land transport and vice versa, which is obtained with the MACYR system will make it possible for the railroad to increase its market in the movement of containers. The minutes that the locomotive is stopped will be used to recharge fuel, water, lubricants and change operators if necessary.

The system contemplates not entering the cities. The road will pass in the perimeter of the metropolitan areas. There will be ground transportation, assigning for each of them a specific place on the street parallel to the railway line. 1. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide an apparatus for moving the containers of land transport to the railway in the shortest time possible.

The movement is carried out in a way parallel to the main road. The railroad loaded with containers leaves the main road, enters the parallel road and stops. Next to the railroad tracks, at a distance of twenty-four meters, there is a broad street where ground transportation is parked, some of them empty and others loaded with containers.

In the space of twenty-four meters, between the railroad cars and the street, there are two tracks separated by twenty-three meters, where the MACYR system is moved.

On the tracks there are two motorized heads that support a bridge at floor level, which joins the two heads.

In bridge means and supported on it, two concentric cylinders, one from the other, move from one side to the other of the MACYR system tracks. The outer cylinder rotates 360 degrees around the inner cylinder to either side by a hydraulic or electric motor. Conical bearings opposed to each other, ensure their movement and maintain a concentric turn.

Two load-bearing nails are mounted on the outer cylinder, opposite one another (at 180 degrees from each other) whose load capacity is twenty tons each. The mounts of the mount-load rotate 360 degrees, when these are located in the upper part a hydraulic system that puts in position a beam (spreder).

The cylinder moves to one end, places the beam (spreder) on the 12,192 mm container. (40 feet); The beam introduces four bolts located in its corners, in the four corners of the container. By means of a hydraulic or mechanical mechanism the bolts rotate and hold the container. The mounts of the load-load are located at the appropriate height, hook the beam (spreder) in the cavity expressly for it.

The cylinder moves hydraulically or mechanically to the other end. In the same way as the one described above, take the other container, move to the center of the beam and turn 180 degrees.

The MACYR system moves to one end and leaves the container you were in the truck in the rail car. Make the described movement to the other side and leave the container that was in the rail car on the truck.

For 6096 mm containers. (20 feet) the nails of the mountaineering load take the container below (normal use) and the same maneuver is performed, for this maneuver the beam (spreder) is not required. 1. BRIEF DESCRIPTION OF THE DRAWINGS Other aspects of the invention and its advantages are highlighted by studying the detailed description together with the drawings.

• Drawing number 4-LA-3-05 shows a perspective view of the MACYR system. • Drawing number 3-LA-3-050 shows a cut of cylinders with the location of bearings and bearing tracks. • Drawing number 3-MT-3-046 shows the displacement system of the concentric cylinders. • Drawing number 3MR-3-012 shows the bearing support. • Drawing number 3-SR-3-045 shows the forklift's nails. • Drawing number 4-LA-3-051 shows the mechanism to place the beam (spreder) in position so that the nails of the mounts-loads take it.

DETAILED DESCRIPTION OF THE DRAWINGS The plane 4-LA-3-05 shows a version of the present invention: tracks parallel to each other, located parallel to the railway and street, are marked in the reference plane with the letter (a). The motorized heads of the MACYR system rest on these tracks (b), both support the beams located perpendicular to the heads and are marked with the letter (c). The concentric cylinders marked with the letter (d) move to each other and another side of the beams in hydraulic or electrically. The mounts of the mount-load are fixed to the outer cylinder opposite 180 degrees one from the other marked with the letter (e). These nails can rotate 360 degrees.

Marked with the letter (f) is the rail car loaded with a container. Marking the letter (g), a land unit is found carrying a container, standing on the street parallel to the MACYR system tracks.

Plane number 3-LA-3-050 shows the two concentric cylinders with their bearings resting on their tracks. These bearings are assembled each independently, and they are adjusted to the tracks by means of the adjusting screw marked in the plane number 3MR-3-012 with the number (1). This ensures a precise fit, facilitates assembly, and a lower cost.

Four sprockets are attached to the base of the inner cylinder. These are driven by an electric motor with a speed reducer. The wheels rest on tracks located in the inner skate of the beams (10), see plan 3-MT-3-046. Beside these tracks there are two racks (11) that ensure a parallel movement and with the power required to move the load of two containers of 12,196 mm. (40 feet). This movement can also be done hydraulically. To provide stability the system has four overload wheels to maintain the verticality of the cylinders.

Plane number 3-SR-3-045 shows how the forklift's nails are fastened to the outer cylinder, and how these nails can take the container from the bottom or top with the beam (spreder) not shown.

The plane number 4-LA-3-051 shows how the mechanism to put the beam (spreder) that holds the container in position to be taken by the nails of the load-bearing is attached to the outer cylinder. In this way the hydraulic mechanism positions the beam (spreder) on the container, the cylinder is removed from the container, locates the nails at the necessary height so that they enter the cavity that the beam has expressly and hydraulically attaches to the beam to start lifting the container.
