Definitions

  • the present invention relates to a railway car for the transportation of debris.
  • Prior art in the design and construction of rolling stock embraces certain types of car by which spoil, rubble and the like can be loaded at an operations site, transported to another location, and dumped.
  • Such vehicles consist generally in two distinct parts, of which a first incorporates the components permitting movement, i.e. pairs of wheels enabling motion along a railway track, and a second consists in a high-sided open topped bin, or skip, resting on a chassis.
  • the bin serves to collect debris dropped in from above by excavating equipment. Naturally enough, there will be a train of such cars lined up at the operations site, and once loaded, the entire train is moved off to a designated dumping ground.
  • a car of the type in question is equipped generally with a number of telescopic arms operated by corresponding pneumatic cylinders mounted between the bin and the chassis; on arrival of the car at the dumping site, the cylinders will be actuated by an operater, whereupon the bin tilts to one side and its contents are discharged onto the ground below.
  • a first drawback is that of the time taken to discharge the debris, and stems from the slow tilt of the bin; in effect, a considerable weight must be handled and it is therefore advisable to proceed with caution, otherwise the balance of the car might be upset, as indeed might the stability of the entire train.
  • a second drawback is concerned with preparation of the ground where the debris is to be deposited; to avoid an accumulation of mounds that would occur if the contents of the bins were to be dumped on level ground, depressions or indeed fully excavated pits are prepared over the entire expanse of the dumping area, serving as a temporary deposit for the material pending its removal and transportation to a permanent site by truck. Such a procedure involves expenditure on personnel and equipment, and considerable loss of time, all of which signifying increased cost to the contractor.
  • a railway car for the transportation of debris is already known from DE-A-24 03 010 and comprises a bin supported on a track by means of two bogies.
  • a horizontal conveyor belt extending longitudinally over the length of the car and serving to receive debris loaded in from outside the car.
  • the conveyor belt is surmounted by a wedge element which is slideably displaceable along the length of the belt and diverts the stream of debris from the conveyor on either side into the bin, thus filling the bin along its length.
  • An endless scraper chain is provided for emptying the bin by conveying the debris to one longitudinal side of the wagon while the chain is moved lengthwise through the bin.
  • the bin has no side wall along the discharge side. This feature requires a very asymmetrical distribution of the debris loaded in the car.
  • the object of the present invention is to overcome the drawbacks outlined above through the provision of a debris transport car equipped with a combination of on-board features designed to enable a rational, speedy and convenient loading and offloading system whereby debris can be dumped successfully even on unprepared ground.
  • the adoption of a chain of conveyor belts ensures swift and rational handling of the debris loaded into the bin; moreover, the third swinging belt permits of dumping material at a distance from the car and thus of dispensing with the need for preparatory excavations.
  • 1 denotes a four-wheel bogie running on railway tracks 21, associated with a horizontal chassis 2 that appears as a platform and supports a bin 3 for the collection of spoil, debris etc., denoted 4 in its entirety.
  • such a car is equipped with a set of features allowing debris 4 to be collected, conveyed and subsequently dumped, consisting essentially in:
  • the bin in which debris 4 is held comprises a fixed structure provided by the upright walls 3, an array of flaps 7, and a floor provided by the horizontal belts denoted 8a and 8b.
  • the first belt 5 occupies a central, longitudinal position over the car and is of length greater than the overall length of the bin 3, as may be observed in fig 1a which shows one of the ends of the belt 5 looped around a relative drum 5t and projecting marginally from the corresponding end of the bin.
  • 6 denotes a wedge shaped element slidably mounted over the first belt 5 and serving to distribute the conveyed debris 4, which is rendered capable of movement horizontally along the entire length of the bin 3 by slide means 11.
  • the wedge element 6 consists in a pair of blades 6a and 6b arranged so as to present a chevron profile when seen in plan; the two blades 6a and 6b connect uppermost with a parallelogram linkage 13 that is fixed in turn to the slide means 11, thereby enabling an adjustment in the height of the wedge element 6 between a lowered limit position, close to the belt 5, and a raised limit position, distanced from the belt (phantom line of fig 1).
  • the slide means 11 consist in a pair of arms 11a and 11b (see fig 2) arranged as a frame embracing the wedge element 6 from either side, which are fastened at one end to the parallelogram linkage 13 and provided at the remaining end, in the example illustrated, with respective wheels 14a and 14b that run on a pair of horizontal rails 15 forming part of the framework supporting the first belt 5 and extending the entire length of the bin 3 on either side of the belt; alternatively, the rails could be associated with the top of the bin itself. It will be observed from fig 2 that the plurality of flaps 7 are arranged in opposing pairs, and combine with the bottom of the bin 3 to create a series of hopper-like modular sections in which the debris 4 is accommodated.
  • the flaps 7 are capable of movement between a limit position in which the modular hopper section is closed and the flaps register in flush contact with the bottom of the bin, and a limit position in which the section is open, whereby the flaps 7 are distanced from the bottom of the bin 3 and allow the debris 4 to fall; in the example illustrated, such actuator means 12 consist in a plurality of hydraulic cylinders 16, one to each flap 7, hinged by one end to the inside of the chassis 2 and by the remaining end to the respective flap 7.
  • the second belts 8a and 8b are disposed with their working surfaces occupying a common plane below the array of flaps 7; the combined length of the second belts 8a and 8b will coincide substantially with the length of the bin 3, thereby ensuring that the debris 4 from all of the modular hopper sections is gathered up; more exactly, the two belts 8a and 8b are positioned end to end and driven in opposite directions, Va and Vb, such that the debris 4 is conveyed toward a single dropping point.
  • 19 denotes a chute installed beneath the dropping point and anchored to the chassis 2, which serves to collect the debris 4 falling from the belts 8a and 8b.
  • the third belt 9 is installed remote from the bin 3 with one end below the chute 19, mounted in such a way as to rotate in a lower plane parallel with the chassis 2.
  • Rotation of the belt 9 is produced by drive means 10 that consist in a slewing ring 17 supporting the end of the belt below the chute 19 (see fig 2) and capable of swinging through an arc of 180°; in practice, the belt 9 would be rotated by the ring 17 between a non-operative position, essentially of longitudinal alignment with the chassis 2, and an operative position substantially transverse to the chassis 2, which is adopted in readiness to discharge the debris 4.
  • the third belt 9 and the slewing ring 17 are protected by a frame 18 of cradle embodiment, which envelops the two components entirely with the sole exception, needless to say, of that end of the belt 9 from which the debris 4 ultimately discharges. Operation of the car will now be described.
  • debris 4 is loaded onto the first belt 5 of the first car by such equipment as may be operating on the site, and conveyed along above the bin.
  • the wedge element 6 of this car and those of successive cars down to the penultimate will be raised, by appropriate positioning of the parallelogram 13, in such a way that the debris 4 can pass right along to the final car, whereas the wedge element 6 of the final car will be stationed at the farthest end of the relative bin 3 and set in the lowered position, such that the debris 4 falls into the modular hopper section beneath.
  • the wedge element 6 moves forward in the direction denoted C, against the direction of the belt 5, in such a way as to prevent any further flow of debris 4 into the first modular section and begin filling the next section back along the direction of flow toward the loading station; once this endmost car has been filled completely, the wedge 6 of the penultimate car is lowered, and the process of filling the relative modular sections will proceed in similar fashion.
  • the final discharge or dumping operation might be speeded up still further by addition of a further belt installed at ground level and combining with the third belt 9 to create an unbroken conveyor facility stretching, for example, to a loading point for road haulage vehicles that will carry the debris away to designated disposal sites.
  • Such an expedient would be especially advantageous when emptying the cars at hardcored sites where there is no possibility of effecting preparatory excavations to receive the debris.
