EA013833B1 - Storage cart - Google Patents

Abstract

A storage cart (1) is equipped with a loading container (5) and with a transfer conveyor belt (10) connecting to a floor conveyor belt (6) and protruding over a front cart end (9) for forwarding stored bulk material. The loading container (5) has two side walls (16) extending parallel to each other, and a rear wall (19) connecting the two side walls (16) to each other on a rear cart end (18) disposed at a distance from the transfer conveyor belt (10). Said rear wall can be modified with regard to the position thereof in relation to the floor conveyor belt (6) such that unit goods can be transported without damaging the floor conveyor belt (6).

Description

The invention relates to a storage car in accordance with the characteristics of the restrictive part of claim 1 of the formula.

Such storage cars are already known from I8 6925366, CB 0442094 or I8 6892648. It is preferable to grip several cars of the same structural type into one loading train. Due to the slopingly positioned and protruding for the front end of the cars of the transfer conveyors, these cars can be loaded and unloaded spontaneously.

From CB 2277725 it is also known to perform a transfer conveyor with the possibility of rotation in a vertical plane. This makes it possible to reduce the height of the fall of the accumulated ballast for ballasting the path.

The objective of the invention is to create a cumulative car of the generic type, the scope of which could be expanded only with a small cost of re-equipment.

According to the invention, this problem is solved by means of an accumulation car of the kind described above with the features given in the characterizing part 1 of the formula.

Using the accumulation car thus constructed, it is possible, by removing or tilting the rear wall, to lower the transfer conveyor above the floor conveyor very close to it, in order to transport even heavy piece goods, such as cut old-year sleepers. By lowering the transshipment conveyor, it is possible to reliably eliminate damage to the floor conveyor by the transported unit loads.

Alternatively, by rotating the rear wall in the opposite direction to the transport direction, you can also create a sort of loading hopper to receive bulk cargo directly from the excavator bucket. Thus, it becomes unnecessary to use an additional conveyor or a special transshipment station at the junction of the construction site and the adjacent track, which is devoid of path.

Other advantages and embodiments of the invention are given in the dependent claims and in the drawings.

Below the invention is described in more detail by the example of its implementation shown in the drawings, in which FIG. 1 is a side view of a loading train made up of several coupled storage cars;

FIG. 2 is an enlarged side view of two storage cars, with the transfer conveyor lowered to a horizontal position;

FIG. 3 is another alternative possibility of use in a schematic side view.

Depicted in FIG. 1 and 2 accumulative cars 1 consist, respectively, mainly of frame 4, moving along path 3 by means of two carriages 2, and a freight container 5 connected to it 5. The floor conveyor 6 passing in the longitudinal direction of the car forms the floor of the freight container 5 and contains a drive 7 to travel in the transport direction 8. At the front end of the freight container 5 with respect to this direction 8, there is provided a transfer conveyor 10, which is mounted on frame 4 under the drop end 11 of the floor conveyor 6, adjoining it. Reloading the conveyor 10 protrudes at an angle to the horizontal upward for the front end 12 of the car and is equipped with a drive 13.

With the help of coupling devices 14, an arbitrary number of uniformly constructed storage cars 1 can be coupled into one loading train 15 moving along the track 3, through which bulk cargo can be accumulated and / or transported. With this coupling of the storage cars 1, the floor 6 and the transshipment 10 conveyors of the individual cars that overlap each other end form a continuous transport path, and the bulk cargo is transferred from the dumping end 17 of the transshipment conveyor 10 to the floor conveyor 6 of the previous one in the transport direction of the storage car.

When the transport speed of the conveyors 6, 10 increases, the bulk cargo is transported through cargo containers 5 only in the longitudinal direction of the train 15. When switching the drive 7 of the floor conveyor 6 to a slow rotational speed, a bulk cone forms in the receiving zone 26, and, accordingly, this cargo container 5 accumulates bulk cargo.

The cargo container 5 contains two side walls 16 parallel to each other, which are interconnected by a rear wall 19 at a rear end 18 of the car remote from the transshipment conveyor 10. The rear wall 19 is rotatable around the axis 21 located in the zone of the floor conveyor 6 at the lower end 20 of the carriage from a vertical position (dash-dotted lines in FIG. 2) to a horizontal position parallel to the floor conveyor 6.

After turning the rear wall 19 to a position parallel to the floor conveyor 6, the adjacent overload conveyor 10 can be rotated around the axis of rotation 22 into a lowered position, in which the drop end 17 is above the floor conveyor 6 very close to it. Thus, instead of bulk cargo, it is also possible to transport heavy unit loads, for example, cut old-year sleepers, without damaging the floor conveyor 6.

- 1 013833

As shown in FIG. 3, alternatively, the rear wall 19 can be rotated in the direction of the rear end 23 of the car frame at an angle α = 30-45 ° to the vertical. While it is preferable if the rear working end 24 of the floor conveyor 6 is removed from the rear end 23 of the car frame a maximum of 1 m.

Thanks to this constructive option, you can load the cumulative car 1 located on the transition section / site with the help of an excavator 25 without using auxiliary means for this.
