Loading train for bulk material

Abstract

A loading train (1) consists of at least two loading wagons (2, 3) for transporting and storing bulk material, each having a wagon frame (5) supported on on-track undercarriages (4), a storage box (6) with a bottom conveyor belt (8) which is situated in the bottom region of the storage box and extends in the longitudinal direction (7) of the wagon, and a pivotable transfer conveyor belt (9) adjoining the bottom conveyor belt (8) and projecting beyond the wagon frame (5). A tilt protection device (11) is provided between the front-most, first loading wagon (3)with regard to a transport direction (10) of the bottom conveyor belt (8)and the following, second loading wagon (2). The tilt protection device (11) is designed for contacting the rearward wagon frame end of the first loading wagon (3) in order to block an upward movement of the wagon frame (5).

(1) The invention will be described in more detail below with reference to embodiments represented in the drawing.

(2) FIG. 1 shows a schematic side view of a loading train,

(3) FIG. 2 shows an enlarged cross-section of the loading train along the line II in FIG. 1, and

(4) FIGS. 3 to 5 show detail views of tilt protection devices.

DESCRIPTION OF THE INVENTION

(5) A loading train 1, shown schematically in FIG. 1, consists of at least two loading wagons 2, 3 for transporting and storing bulk material. Each loading wagon 2, 3 is essentially composed of a wagon frame 5 which is supported on on-track undercarriages 4 and has a storage box 6. Located in the bottom region of the storage box 6 is a bottom conveyor belt 8 extending in the longitudinal direction 7 of the wagon, and a pivotable transfer conveyor belt 9 adjoining the bottom conveyor belt 8 and projecting beyond the wagon frame 5 is arranged for passing bulk material on to a further loading wagon 3. A tilt protection device 11 is provided between the front-most, first loading wagon 3with regard to a transport direction 10 of the bottom conveyor belt 8and the following, second loading wagon 2. The loading wagons 2, 3 are connected to one another by a coupling 12.

(6) The tilt protection device 11, which has a front and a rear end 13, 14 (FIGS. 3 and 4)with regard to the longitudinal direction 7 of the wagonis fastened with the rear end 14 to the second loading wagon 2. The front end 13 of the tilt protection device 11 is designed for contacting a rearward wagon frame end 15 of the first loading wagon 3, or for detachable connection to the wagon frame end 15, in order to block an upward movement of the wagon frame 5.

(7) As shown in FIGS. 2 and 3, the front end 13 of the tilt protection device 11 is configured for resting on the rearward wagon frame end 15 of the first loading wagon 3. At the front end 13, the tilt protection device 11 has a support ram 16, adjustable in vertical direction, for placement on the rearward wagon frame end 15 of the first loading wagon 3. In an expedient manner, the supporting takes place on a support plate 17 attached to the wagon frame 5. The support rams 16 are advantageously designed as hydraulic cylinders; alternatively, an embodiment in the shape of a spring element would also be conceivable.

(8) The tilt protection device 11 is connected to a control device 18 which is connected to measuring implements 19 for detecting a tilting motion of the front-most loading wagon 3.

(9) As can be seen mainly in FIG. 4, two tilt protection devices 11 are provided, spaced from one another in a transverse direction of the wagon extending perpendicularly to the longitudinal direction of the wagon.

(10) The tilt protection device 11 visible in FIG. 5 is fastened to the second loading wagon 2 for pivoting about a vertical axis 20. Due to the support plate 17 which, in this embodiment, is mounted underneath the wagon frame 5 of the loading wagon 3, a form-fitting connection 21 between the two loading wagons 2, 3 ensues.

(11) The mode of function of the tilt protection device 11 will be described in more detail below. FIG. 2 shows the front-most loading wagon 3 with the transfer conveyor belt 9 pivoted far to the side. Since the loading wagon 3 is furthermore situated in a track curve, it is already in an inclined position due to the curve super-elevation. The weight of the bulk material to be discharged causes an additional load. This results in a tilting moment (arrow 22) due to which the wagon frame 5 first undergoes an upward movement, and then the loading wagon 3 could lift off from an outer rail 23 of the track curve and topple over. In order to compensate the tilting moment and keep the loading wagon 3 in balance, the tilt protection device 11 located above the outer rail 23 is actuated. The hydraulic cylinder acts upon the wagon frame 5 of the loading wagon 3 via the support plate 17 and thus prevents the loading wagon 3 from lifting off the rail 23. If unloading takes place towards the other side, the opposite tilt protection device 11 is employed in the same manner.

(12) Due to the already described use of the controland measuring devices 18, 19, the registering of the tilting moment and the actuation of the tilt protection devices 11 can be largely automatized, as a result of which it is possible to reliably preclude any handling errors.

(13) In closing, it is pointed out that the tilt protection device 11 could also be fastened to the wagon frame end 15 of the first loading wagon 3. In this alternative, the required contacting or the detachable connection takes place with the rear end 14 of the tilt protection device 11 at the wagon frame 5 of the second loading wagon 2.
