DEVICE AT A SET OF WAGONS HAVING LATERALLY TILTABLE WAGON BODIES

Abstract: Device at a set of wagons having laterally tiltable bodies (4) for bridging the distance between the wagon bodies (4). When loading a set of wagons with laterally tiltable wagon bodies so-called continuous loading cannot be utilized as in that case spilling in the space between the wagon bodies occurs. It is the object of this invention to enable continuous loading without wastage by means of the device of the invention. The device of the invention consists of a flap (13) which is pivotably attached to the rear end of the wagon body (4) as seen in the direction of travel of the train. The flap (13) is pivotable about an axis transverse to the longitudinal direction of the set of wagons and has such an extension that it overlaps the following wagon body (4).

Description: Device at a set of wagons having laterally tiltable wagon bodies 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 a not inessential 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 fal¬ ling down " between the wagon bodies. It is the object o*f 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 descri¬ bed 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 in¬ vention. The set of wagons shown in Fig. 1 comprises four wagons 1 , which are coupled together with so-called 3-point suspen¬ sion. 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 ad¬ joining wagon. Thanks to said 3-point suspension the set of wagons will have a good flexibility with a little risk of derailment also on a roughly laid rail. The wagon bodies 4 rest on underframes 5. Each under- frame 5 has two upright support means 6 placed along one long side of the underframe and sloping outwardly relative to the longitudinal centre 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 show a guide roller 8, which is used in con¬ nection with 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 have each a drive roller 10 mounted on a vertical shaft, which coopera¬ tes 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 it 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 it 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 11 ' 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 helix 14 and the guide roller 8' • ' the wagon body 4 f l t will be swiveled about the hinges 7. The hatch 13'" pivotably arranged at said wagon body will then accompany the tilting movement of the wagon body 4 ■ • , (the right posi¬ tion in Figs 2a and 2b) . At additional movement of the set of wagons in the di¬ rection of the arrow 15 tilting movement of the wagon body 4 ■ ' * is continued until the latter has reached the inter¬ mediate emptying position in Figs. 2a and 2b and the right emptying position in Fig. 2c, respectively. The goods will then tumble out of the wagon body 4 I ! and down into an emptying hopper or the like. Due to the force of gravity the hatch 13' * will be turned to the left in Figs. 2a and 2b, whereby it is ensured that the goods possibly lying thereon will also fall down into the emptying hopper. When the intermediate wagon body 4' 1 in Figs. 2a and 2b has emptied its goods it will be returned to the position entered by the left wagon body 4' in Figs. 2a and 2b by the influence of the emptying helix 14 at the continued motion of the wagon set. In a certain position of the returning movement of the wagon body 4 11 the hatch 13*' will be turned back to a position where it extends straight outwards la- terally from the wagon body 4, see the right hatch IS'' 1 in Fig. 2a. At said return of the wagon body 4'' the associated hatch 13'' will be caught by the rear wagon body 4' 11 going up by the action of the emptying helix 14. Thus, the hatch 13' * will enter a position where its free edge is upwardly turned and abuts the rear wagon body, which is then approach¬ ing its emptying position. The free edge of the hatch 13' ' thus slides along the short side of the rear wagon body. When the wagon body 4' 1 being in the intermediate posi- tion has emptied its goods it will be. tilted by the action of the emptying helix 14 back to the position entered by the left wagon body 4' in Figs. 2a and 2b. The end section of the wagon body 4'' will then slide relative to the hatch 13' of the wagon body 4'. By making the end sections of the wagon bodies 4 relatively smooth the risk is eliminated that the hatch 13' will hook onto said end section due to the frictior: between the free edge of the hatch 13' and ' e front end section of the wagon body 4''. When the wagon body 4' 1 has been tilted back to the position of the wagon body 4' in Figs. 2a and 2b the hatch 13' will fall down above the front end of the wagon body. By this the wagon body 4' and the flap 13' have again entered the starting position in which loading of goods can take place. As is most clearly apparent from Fig. 1 the flap 13 has raised lateral edges lengthwise of the wagon set. In this way the risk of wastage of the goods getting onto the flap 13 at loading will be reduced. The invention is by no means restricted to the illustra- tive example described above but can be freely varied within the scope of the appended claims.
