DESCRIPTION:
BRIEF SUMMARY
This invention relates to a device at a set of wagons having laterally tiltable bodies for bridging the space between the wagon bodies.
At laterally tiltable wagon bodies one is at present compelled to use so-called intermittent loading, i.e. the wagon body is advanced to a position beneath e.g. a loading hopper, after which the wagon body is stopped and loading takes place. The next wagon body is thereafter driven up.
This type of loading is extraordinarily time-consuming due to the continual stops and starts of the wagon set which must be made. Moreover, said stops and starts involve an unnecessary stress on the material.
Thus, it is desirable that so-called continuous loading can be used which, however, cannot be done as, in that case, an unacceptable wastage would result due to the goods falling down between the wagon bodies.
It is the object of this invention to provide a device of the kind mentioned above, which enables a continuous loading of the wagon bodies without any appreciable spill. This is realized in an utterly simple and elegant way by means of a device having the characteristic features set out in the appended claims.
An illustrative example of the invention will be described below with reference to the enclosed drawings, wherein FIG. 1 shows a set of wagons with laterally tiltable bodies provided with devices according to the invention and FIGS. 2a, 2b and 2c show the dumping of laterally tiltable wagon bodies, which are provided with devices according to the invention.
The set of wagons shown in FIG. 1 comprises four wagons 1, which are coupled together with so-called 3-point suspension. This means that the wagons 1 have a wheel pair 2 only in the region of one of their ends while their other ends are provided with a tension flange 3, which at coupling of the wagons is hooked onto a tow hook or the like of an adjoining wagon. Thanks to said 3-point suspension the set of wagons will have a good flexibility with little risk of derailment on a roughly laid rail.
The wagon bodies 4 rest on underframes 5. Each underframe 5 has two upright support means 6 placed along one long side of the underframe and sloping outwardly relative to the longitudinal center line of the set of wagons.
At the upper ends of the support means 6 hinges 7 are arranged, which connect the wagon bodies 4 with the support means 6. Thanks to this constructive embodiment the wagon body 4 can be tilted laterally at emptying, which will be described more in detail below.
On the long side turned from the hinges 7 the wagon bodies 4 also shown a guide roller 8, which is used in connection with the tipping of the wagon bodies.
In the illustrative example shown two opposed electric drive stations 9 are arranged on both sides of the set of wagons for its propulsion. Said drive stations 9 each have a drive roller 10 mounted on a vertical shaft, which cooperates with a side member 11 of the underframe 5. The drive roller is rotated by means of an electric motor 12 of the drive station 9.
The distance between two adjacent wagon bodies 4 is bridged by a flap 13, which is pivotably attached to one wagon body while its abuts loosely from above against the other wagon body. Due to the arrangement of said flaps 13 a continuous goods receiving line along the entire set of wagons is formed. Thanks to this a so-called continuous loading can be utilized. The goods thereby getting onto the flaps 13 either remain there or fall down by vibration or the like into the adjoining wagon bodies 4. Raised lateral edges 13a of the flaps 13 ensure that goods will not fall down laterally.
When emptying the set of wagons described above each wagon passes an emptying station at which a so-called emptying helix 14 is arranged, see FIGS. 2a-2c.
The direction of travel of the set of wagons is shown by the arrow 15 in FIG. 2a.
When the set of wagons appears at the emptying station guide rollers 8'" of the right wagon body 4'" in FIGS. 2a and 2b will be entered into the emptying helix 14 at its right end in FIGS. 2a and 2b. By cooperation between the emptying
