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). The loading container has two side walls (16) extending parallel to each other, and a rear wall (19) connecting the two side walls to each other on a rear cart end (18) disposed at a distance from the transfer conveyor belt. The rear wall is modified according to the position in relation to the floor conveyor belt.

Description

0702 1/8 A STORAGE WAGON [0001] The invention relates to a storage wagon according to the features of the introductory part of claim 1. [0002] According to US 6 925 366, GB 0 442 094 or US 6 892 648, various storage wagons of this type are known. In this, it is advantageous to couple several wagons of like design together into a loading train. By means of the transfer conveyor belts arranged inclined and projecting beyond the front end of the wagon, these wagons can load and unload themselves automatically. [0003] From GB 2 277 725 it is also known to configure the transfer conveyor belt so as to be pivotable in a vertical plane. Thus it is possible, for ballasting the track, to reduce the height of fall of the stored ballast. [0004] It is the object of the present invention to-create-a storage-wagorrof the specified kind of which the range of applications may be expanded with only small retooling expense. [0005] According to the invention, this object is achieved with a storage wagon of the type mentioned at the beginning by means of the features cited in the characterizing part of claim 1.

2/8 [0006] With a storage wagon designed in this manner it is now possible, by removing or folding down the rear wall, to lower the preceding transfer conveyor belt to just above the bottom conveyor belt in order to be able to transport also heavy piece goods, such as fragmented old sleepers, for example. By lowering the transfer conveyor belt, any damage to the bottom conveyor belt by the piece goods to be transpoerted can be reliably precluded. [0007] Alternatively, however, it is also possible, by pivoting the rear wall oppositely to the transport direction, to create a kind of hopper to receive bulk goods directly from an excavator shovel. This saves the necessity of using an additional conveyor belt or of a special transfer station at an intersection between a trackless construction site and an adjacent track. [0008] Additional advantages and features of the invention become apparent

from-the-dependent-taims-and-the-drawing.

[0009] The invention will be described in more detail below with reference to an embodiment represented in the drawing in which [0010] Fig. 1 shows a side view of a loading train composed of several storage wagons coupled together, Fig. 2 shows an enlarged side view of two storage wagons, with a transfer conveyor belt being lowered 3/8 into a horizontal position, and Fig. 3 shows a schematic side view of a further alternative possibility of operation. [0011] Each of the storage wagons depicted in Figs. 1 and 2 essentially consists of a wagon frame 4 - mobile via two on-track undercarriages 2 on a track 3 - and a loading container 5 connected to the same. A bottom conveyor belt 6, extending in the longitudinal direction of the wagon, forms the floor surface of the loading container 5 and has a drive 7 for movement in a transport direction 8. At the front end 9 of the loading container 5, with regard to said transport direction 8, a transfer conveyor belt 10 is provided which is mounted on the wagon frame 4 below a discharge end 11 of the bottom conveyor belt 6, adjoining the latter. The transfer conveyor belt 10 is designed leading upward at an angle to the horizontal, projecting beyond a front wagon end 12, and is equipped with a drive 13. [0012]ith-thLeaid*OfTCuping evices 14, it is possible to couple any desired number of similarly designed storage wagons I into a loading train 15, mobile on the track 3, by means of which bulk material can be stored and/or transported. When storage wagons 1 are coupled to one another like that, the bottom- and transfer conveyor belts 6, 10, overlapping one another at the ends, of the individual wagons form a continuous conveyor belt road wherein the bulk material is passed on 4/8 in each case from a discharge end 17 of a transfer conveyor belt 10 to the bottom conveyor belt 6 of the storage wagon 1 preceding in the transport direction. [0013] In the case of higher transporting speed of the conveyor belts 6, 10, the bulk material is merely transported through the loading containers 5 in the longitudinal direction of the loading train 15. If, however, the drive 7 of a bottom conveyor belt 6 is switched to slow circulation speed, then this causes the formation of a bulk cone in a receiving region 26 underneath the discharge end 17 and, correspondingly, the storing of the bulk material in this loading container 5. [0014] The loading container 5 has two side walls 16, extending parallel to one another, which are connected to one another by a rear wall 19 at a rear wagon end 18 remote from the transfer conveyor belt 10. The rear wall 19 is pivotable about an axis 21, positioned at a lower end 20 -of-the-wall-in-the-region-of-the-bottom-conveyorbeit 6, frora- vertical position (see dash-and-dot lines in Fig. 2) into a horizontal position extending parallel to the bottom conveyor belt 6. [0015] As soon as the rear wall 19 has been pivoted into a position parallel to the bottom conveyor belt 6, the adjoining transfer conveyor belt 10 can be adjusted about a pivot axis 22 into a lowered position in which the discharge end 17 is situated just above the bottom conveyor belt 6.

5/8 Thus, it is now possible to transport - instead of bulk material - also heavy piece goods, such as fragmented old sleepers, for example, without damaging the bottom conveyor belt 6 in the process. [00161 Alternatively, as shown in Fig. 3, the rear wall 19 can be pivoted in the direction toward a rear wagon frame end 23 at an angle a of about 30 to 450 with respect to the vertical. During this, it is advantageous if a rear deflection end 24 of the bottom conveyor belt 6 is spaced from the wagon frame end 23 by at most one meter. [00171 With this structural variant, it is possible to load the storage wagon 1, positioned at a transition area of track and construction site, by means of an excavator 25 without requiring auxiliary means to do so.
