Description

The invention relates to an unloading device for rail freight cars, Trucks and other types of wagons which, in a known manner, have an in the longitudinally subdivided floor is used, which is arranged to be movable towards the center of the car. According to the invention is now each of the two longitudinal panels that make up the floor in the transverse direction divided into hatch panels. Each Luicenplatte has a special lifting device provided in order to be able to open the individual hatch panels individually and one after the other by a single crank or the like.

It has already been proposed to divide the car body into individual cargo spaces by means of special partition walls, the floor openings of which, to be closed by sliding flaps, formed the mouths of lateral unloading channels. However, this purchase order is a special structure of the wagon frame ■ ahead, and there are known in railway operations special cars. In the unloading device according to the invention, the usual trolley frames and boxes can be used; it is only necessary to subdivide the box floor in the manner described above and to arrange the individual hatch panels in a displaceable manner. The unloading device can also be easily installed in existing wagons. By 'the possibility of the hatch panels individually; and to move them one after the other, relatively little forces are necessary to unload the contents of the car, and it is also possible to throw the contents of the car into narrow shafts or into sacks

or to empty barrels that are located under the car body.

Another advantage is that the car body space can easily be used to transport General cargo can be used, which is not the case with the special wagons for granular goods or the like the case is. Pulling ropes of different lengths are used to pull open the hatch panels by means of a common shaft ίο those behind or next to each other To be able to open hatch panels one after the other. To wind up the pull ropes are loosely on the drive shaft arranged cable drums connected to the shaft by coupling elements are inevitably connected. The individual hatch panels have special attachments Mistake. Each stop strikes at the end of the opening stroke of a hatch plate against the Conical surface of a clutch, the clutch disengages and thus switches the corresponding one Remove the cable drum from the drive shaft. In a particular embodiment of the invention are two opposite hatch panels under the fixed central one Part of the loading area can be shifted one above the other, making it possible to also wagons with a small lateral overhang and narrow-gauge vehicles with the unloading device equip. The invention is shown in the drawing in two embodiments on one example selected motor vehicle illustrated.

Fig. 1 and 2 show the first embodiment in a view from above or in cross section along the line AB in Fig. 1.

Fig. 3 shows in detail the drive shaft with the coupling of the cable drums.

FIGS. 4 and 5 illustrate a second embodiment in a view from above of the rear end of a truck body and in a section along line CD in FIG.

In the figures, 1 means the chassis of a motor vehicle on which in known Way on continuous longitudinal members 2 cross members 3 are arranged, which the Carry car body 4. The latter has the invention in place of the otherwise usual, undivided floor area consisting of a plurality of individual plates Floor, the side floor panels 5, 5 'by means of a suitable pulling device under the fixed .. center part 6 the floor area can be pulled. The middle part 6 of the bottom surface 6 is expedient provided with an attachment sloping on both sides (see Fig. 2 and 5), which can be removed from the floor surface 6 is attached.

Under the car body 4, a shaft 7 is mounted, which approximately in the middle of the various lateral base plates 5, 5 'carries two cable drums 8, 8' arranged next to one another, over which pulling cables 9, 9 'are guided. The latter are so placed on the drums 8, 8 'that when the shaft rotates / by means of a hand crank 10, the floor panels 5, 5 'pulled from both sides towards the center will.

So that you are not forced to rotate the axis 7 at the same time all To move floor plate pairs 5, 5 ', the pull cables 9, 9' are of different lengths, e.g. the base plates 5, 5 'which are initially located on the crank are attached by means of tensioned ropes 9, 9' their cable drums 8, 8 'attached, while those arranged at the front end of the car body The pull ropes sag. As a result, when the shaft 7 rotates, the rearmost floor panels 5, 5 'are opened immediately, while the front floor panels 5, 5 'are not yet tightened, but only after their tightening ropes are taut. So now after complete opening of a pair of slide plates 5, 5 'the further rotation of the shaft 7 is possible, the cable drums 8, 8' are decoupled as soon as a bottom slide plate 5 or 5 'is fully open. The uncoupling device consists, as Fig. 3 shows, of a conical disk 11, which by means of a spring and Groove 12 on the shaft 7 is displaceable in the axial direction and at its end a coupling 13 carries, which is usually in a corresponding ring gear · 14 which is loose on the Shaft 7 seated cable drums 8, 8 'engages. At the inner edge of the floor panels 5, 5 'are Ram rollers or rollers 15, 15 'provided, which, as soon as the base plates 5, 5 'are fully open, against the conical surface of the conical disc Press 11 so that the latter moves in the direction of the arrow, thereby releasing the clutch 13, 14 is solved. As a result, the floor panels open when rotating the shaft 7 is no longer attracted, while the not yet fully opened plates to continue moving towards the center of the carriage. In this way it becomes in the balance: - box 4 housed bulk goods one after the other through the bottom plates 5, 5 ' released openings emptied downwards, no being due to the conical design of the middle bottom part 6 also the bulk material located in the middle of the wagon up to the complete Emptying the car body slides off.

After the load has been completely thrown off, the floor panels 5, 5 'of Withdrawn by hand using suitable handles not shown in the drawing or automatically, so that the bottom of the car body 4 is closed again. Arranged on the side walls of the car body 4 Staples 16, 16 'secure the closed one

Position of the floor panels 5, 5 'against any unintentional Move.

The base plates 5, 5 'can be arranged to slide in guides of the cross members 3. The plates 5, 5 'according to the embodiment according to Figs. 1 and 2 can be withdrawn from both sides up to the shaft 7, or according to the embodiment according to Figs , '9' can attack the outer edge of the plates 5, 5 '. By choosing the ropes 9, 9 'of different lengths and arranging the disengaging clutch ir, 11' described above between the rope drums 8, 8 ', the plates 5, 5' provided ^{with stop pins 15 °, I5 a 'can be tightened one after the other.} The advantage of this embodiment is that the fixed bottom part 6 can be made narrower than in the embodiment according to FIGS.

The mode of operation of the invention is as follows:

If the car body 4 loaded with bulk material is to be emptied, the shaft 7 is rotated by turning the crank 10 when the clutches 11 are engaged, whereby the first pair of floor plates 5, 5 'is attracted simultaneously or one after the other. After these plates are partially opened and thereby the friction between the plates and the load resting on them is reduced, the second pair of floor plates 5, 5 'is set in motion, which is followed after some time by the third and fourth pair of plates. As soon as a pair of plates is completely open, its stop ^{devices 15, 15 'or 15 0} , 15 ^s hit the conical disk 11 or 11', whereby the associated cable drums 8, 8 'are decoupled and the shaft 7 can be rotated further. In this way, one after the other all the bottom plate pair <: according to the center to move until the car box is completely emptied.

If you want to throw the bulk goods in a narrow shaft, you can the previously disengaged clutches 11, n ' Engage one at a time by hand after the vehicle is with the clutch engaged corresponding cross section has been driven over the shaft. That way you can you throw the entire load one after the other into a narrow shaft, on a narrow one Pile up the surface or, if the base plate is partially open, directly into sacks, barrels or the like. empty.

The advantages which the invention achieves over the known exist in the fact that one can effect a complete emptying of the car with simple means can, with the bulk material not, as is usual, on both sides or behind the Car is unloaded, but below the car. The one for opening the valve plates The effort required is low due to the successive actuation of the individual base plates.

The invention can be applied to rail freight cars, motor vehicles and vehicles more commonly Type will be used if the construction described is modified accordingly.
