BULK MATERIAL LOADING WAGON

Abstract

A bulk material loading wagon (1) for incorporation into a loading train consisting of several such wagons has a storage box (3) for storing bulk material, the storage box being open at the top and fastened to a wagon frame (2), andassociated with the storage boxa bottom conveyor belt (5) extending in the lower region of the storage box (3) and in the longitudinal direction of the wagon. The wagon frame (2) is equipped with an opening (16), arranged between two adjacent on-track undercarriages (14), for passage of a lower section adjoining the lower deflection end (9)of a transfer conveyor belt (8). A drive (18) is provided for displacement of the transfer conveyor belt (8) in its conveying- or longitudinal direction (4) through the opening (18) relative to the wagon frame (2).

Claims

1. A bulk material loading wagon for incorporation into a loading train consisting of several such wagons, including a storage box for storing bulk material, the storage box being open at the top and fastened to a wagon frame, andassociated with the storage boxa bottom conveyor belt, extending in the lower region of the storage box and in the longitudinal direction of the wagon, which is designed endless while forming two deflection ends spaced from one another in the conveying direction and has a conveying drive, and further including a transfer conveyor belt arranged at an angle to the bottom conveyor belt, the transfer conveyor belt having a lower deflection end adjoining the wagon frame and an upper deflection end spaced farther from the wagon frame, wherein, between two adjacent on-track undercarriages, the wagon frame has an opening for passage of a lower sectionadjoining the lower deflection endof the transfer conveyor belt, and that a drive is provided for displacement of the transfer conveyor belt in its conveying- or longitudinal direction through the opening relative to the wagon frame.

2. The wagon according to claim 1, wherein the wagon frame is composed of two frame parts, arranged one following the other in a longitudinal direction of the wagon, each of which is connected to two on-track undercarriages spaced from one another in the longitudinal direction of the wagon, wherein the opening for passage of the transfer conveyor belt is arranged between the two on-track undercarriages of the frame part connected to the transfer conveyor belt.

3. The wagon according to claim 1, wherein a conveying drive connected to the transfer conveyor belt is designed for selective reversal of the conveying direction for the bulk material in the direction towards the upper or the lower deflection end.

Description

[0008] The invention will be described in more detail below with reference to an embodiment represented in the drawing in which

[0009] FIGS. 1 and 2 each show an enlarged side view of a bulk material loading wagon, and

[0010] FIG. 3 shows a schematically simplified loading train.

[0011] A bulk material loading wagon 1, depicted in a schematically simplified manner in FIGS. 1 and 2, has a storage box 3 for containment and storage of bulk material, the storage box being upwardly open and supported on a wagon frame 2. In the lower region of the storage box 3, a bottom conveyor belt 5 extending in a conveying direction or longitudinal direction 4 of the wagon is provided in place of a bottom surface. Said bottom conveyor belt 5 is designed endless while forming two deflection ends 6 spaced from one another in the conveying- or longitudinal direction 4 of the wagon, and is connected to a conveying drive 7.

[0012] Provided immediately in front of the front deflection end 6 of the bottom conveyor belt 5with regard to the conveying direction 4is a transfer conveyor belt 8 positioned at an angle to the former and projecting beyond the wagon frame 2. Said transfer conveyor belt 8 has a lower deflection end 9 adjoining the wagon frame 2 and an upper deflection end 9 spaced farther from the wagon frame 2 and is connected to the wagon frame 2 for rotation about a vertical axis by means of an articulation 10. A conveying drive 11 connected to the transfer conveyor belt 8 is designed for selective reversal of the conveying direction 4 for the bulk material in the direction towards the upper or lower deflection end 9.

[0013] The wagon frame 2 connected to the storage box 3 consists of two frame parts 12, 13 arranged one following the other in the longitudinal direction of the wagon. Each of these frame parts 12, 13 has two on-track undercarriages 14 spaced from one another in the longitudinal direction of the wagon, and both frame parts 12, 13 are connected to one another by means of a coupling rod 15.

[0014] Between two adjacent on-track undercarriages 14 of the front frame part 12, the wagon frame 2 has an opening 16 for passage of a lower section 17adjoining the lower deflection end 9of the transfer conveyor belt 8 (FIG. 2). A drive 18 connected to the articulation 10 is provided for this displacement of the transfer conveyor belt 8 in its conveying- or longitudinal direction 4 through the opening 16 relative to the wagon frame 2.

[0015] FIG. 3 shows a loading train 19 which is composed of an arbitrary number of bulk material loading wagons 1 arranged one following the other in the longitudinal direction of the wagon and coupled to one another. This makes it possible to transport stored bulk material via the transfer conveyor belt 8 onto an adjoining, preceding bulk material loading wagon 1. For that purpose, each of the transfer conveyor belts 8 is in the extended position visible in FIG. 1, in which the upper deflection end 9 in each case projects beyond a front end 20 of the wagon frame 2.

[0016] As shown in FIG. 2, the transfer conveyor belt 8 has been retracted with the aid of the drive 18 by guiding the lower section 17 through the opening 16 of the front frame part 12. in this position, the upper deflection end 9 no longer projects beyond the front end 20 of the wagon frame 2.

[0017] In this position, a further variant of working operations is possible, as desired, in thatby reversing the conveying direction 4 of the transfer conveyor belt 8bulk material which has been discharged by the bottom conveyor belt 5 via the front deflection end 6 thereof can be discharged in a targeted manner via the lower deflection end 9 upon a track 21, located thereunder, for ballasting the same.

[0018] The storage box 3 is supported via two support devices 22 on the front and rear wagon frame 2. The front support device 22 has a drive, not shown in detail, by means of which the storage box 3 is vertically adjustable relative to the front wagon frame 2 by a small degree. With this, the transfer conveyor belt 8in the position shown in FIG. 1can be pivoted transversely without problems in order to be able to unload the stored bulk material laterally next to the track.
