Definitions

  • Bulk cargos such as coal, gravel, sand cargos and the like are normally transported by rail in hopper cars; such cars are usually fitted with two separate bins for loading, while the discharge of the materials contained therein is effected by gravity through two large side hatches for each bin, wherein the hatches are opened by drive means into dump pits.
  • a car has also been provided by the same owner of the present invention, having independent drive means for the hatches which may be actuated from the control platform, but the car, however, cannot be operated from earth at both ends and it is also fitted with a complex mechanism for operating the opening devices.
  • a further requirement relates to the necessity, in case of improper functioning of the drive and transmission means, of avoiding the unintentional opening of a pair of hatches which are out of the discharge area at the same time of, or instead of the hatches whose opening has been operated.
  • a railway hopper car with bilateral gravity discharge and separate bins comprising a container body formed by two or more consecutive, separate loading bins, each of these bins being provided with two openings on the opposite sides of the car, which may be closed by means of hatches hinged at their upper side, each of the hatches being fitted with a plurality of locking hooks along the lower border; the hooks are fixedly carried by a shaft which is rotatively supported on the body of the car; the shafts carrying the locking hooks relative to the hatches of each of the loading bins being arranged to rotate, at choice, for unlocking the opening of the hatches by means of mechanical transmission lever mechanisms, through a reduction gear of the irreversible type which is hand-controlled by means of shanks accessible from earth which are directly connected to the reduction gear and, in addition, by means of a handwheel which may be connected to the reduction gear through a mechanical transmission comprising a selector capable of
  • the lever mechanisms comprise a rocker keyed to the output or slow shaft of the reduction gear, at the ends of which there are hinged the extremities of two connecting rods which are, at the opposited extremities, hinged to two arms joined to the shafts carrying the locking hooks, wherein the rotation in one direction of the rocking lever is transmitted to the arms through the connecting rods, so as to cause rotation of the shafts in the sense suitable to disengage the locking hooks from the hatches, and in the opposite sense so as to cause the clamp of the hatches by means of the locking hooks.
  • the axis of the rocker intersects the action axis of both the connecting rods or is laying beyond the axis, in the closing direction.
  • the handwheel may be connected, through the selector and possible transmission shafts, to every reduction gear actuating the couple of hatches of each separate bin of the car; therefore, it is possible, by this way, to operate the opening of the selected couple of hatches by means of the handwheel itself.
  • At least one of the locking hooks of each hatch is provided with a hindering foot which projects upwards, beyond the edge of the hooks, and interfers with the opening path of the hatches when the hooks are in a first rotation position apt to free the hatches, the foot being free to rotate in the sense of the opening and rotationally blocked in the opposite sense, being capable in such rotation position of the hooks of non hindering the hatches from a free opening and at the same time, however, hindering them from a total closure movement, whereas a further rotation of the shafts carrying the locking hooks bears the hindering foot, or feet, out of the movement path of the hatches, thereby making their closing possible.
  • the means for driving the opening of the hatches consist of shaped arms fixedly joined to the shafts which carry the locking hooks, having at their ends rollers suitable to act against sliding blocks. linked to the flanks of the hatches when the shafts are rotated in the opening sense beyond the unlocking point of the locking hooks and the hindering feet
  • the means signalling the opening of the hatches consist of two flags for each couple of hatches, which can rotate between a position enclosed in the side shape of the car and a position projecting from same; the flags being rotationally driven by connecting rods and cranks actuated by a staff hinged to a swivelling block which by gravity maintains the flags projecting out of the car shape, there being provided an arm joined rotationally to the rocker, suitable to act on the swivelling block when the rocker is rotated into the closing position, beyond the intersection position of its rotational axis with the action axes of the connecting rods.
  • the selector is formed by a bilateral clutch which is rotationally joined, through a chain transmission or the like, to the handwheel and may be rotationally coupled, through a control lever, either with a corresponding clutch carried by a transmission shaft connected to a reduction gear relative to a couple of hatches located remote from the handwheel, or to a transmission shaft connected to a reduction gear relative to a couple of hatches located adjacent to the car head carrying the handwheel; the transmission shafts being independently supported by self-lubricating bushes carried by separate supporting elements and both being fixed to the car structure, so that the possible seizing of a bush may not bring the non selected shaft into rotation.
  • a hopper car is usually formed by a body 1 subdivided into two bins 2, 3 separated by a wall 4. fnside of the loading bins there is provided a prismatic element 5, whose contour is dash-lined in the figure, having two oblique surfaces suitable to convey the contained ma- - terial towards the couples of hatches 6, 7, relative to the front bin 2 and the back bin 3 respectively, with reference to the control platform 8 of the car.
  • the hatches 6, 7 are hinged, adjacent to their upper side, to the body 1 of the car, as shown in figure 1 and their center of gravity is so provided that they may rest in closure position by effect of their own weight
  • the clamp of the hatches 6,7 in the closure position capable of standing the thrust of the material contained in the car is assured by a plurality of locking hooks 9,9a, supported by shafts 10, located below the lower border of the hatches, at the two opposite sides of the car.
  • the opening of the hatches for enabling to discharge the material contained in one of the two bins 2,3 of the car, is caused by the thrust of the material itself which flows along the oblique flanks of the inner prismatic element 5 when the shafts 10, carrying the locking hooks 9,9a relative to the couple of hatches whose opening has been selected, are rotated of an angle sufficient to disengage the hooks 9,9a from the border of the hatches (see fig. 3 and 4).
  • Rotation of the shafts 10 is achieved by means of a drive group, as illustrated in figure 2 in schematic form and partially visible.
  • the drive group is represented by thick lines whereas the extemal shape of the car is represented by thin lines; it comprises a handwheel 11 connected through a chain 12 to a selector 13 suitable to select the pair of hatches, in the front or back side, which are to be opened.
  • the selector 13 may, in fact, connect the handwheel 11, through the gear wheels 15, 1 6 and a second transmission chain 1 7, to a shaft 18 that is in turn connected, through a bevel gears pair 19, to the input or quick shaft of a reduction gear 20 or to the cardanic transmission shaft 14, which is coupled, at the opposite end of the car, to a second bevel gears pair 19a and to a second reduction gear 20a.
  • the output shaft of the reduction gears 20 and 20a carries a rocker 21, at the ends of which are connected the shaped connecting rods 22, 23 which are pivoted at their end on the arms 24 joined to the shafts 10 carrying the hooks 9, 9a.
  • the locking hooks 9, arranged in middle position along the border of the hatches 6, 7 are shaped as shown in the left side of figure 3; the end locking hooks 9a are shaped as illustrated in the right portion of figure 3 and also in figures 4 and 5, and exhibit a projecting part which carries a - pivot 28 about which the hindering foot 29 may swivel, being fitted with a counterweight 30 and resting against the stop pin 31.
  • the hindering foot 29 does not represent an obstacle to the hatches movement as it is free to swivel about the pivot 28 under the thrust of the hatches themselves, as shown by dot-and-dash line in the right part of fig. 4; in the closing phase of the hatches, under the action of their own weight, when the thrust produced by the flowing material is lowering, the hindering feet 29 blocks the hatches themselves in partial cpening position, as shown by a dot-and-dash line in the left part of fig.
  • the input shafts to the reduction gears 20, 20a are besides connected with the shanks 32 for operation from earth, by which it is possible to carry out the operation of opening the hatches from earth; this operation is only possible when the selector 13 is in idle position, as the reduction gears 20, 20a are of the irreversible type, for example an endless screw, in order to prevent the handwheel 11 from being unvoluntarily brought into rotation by actuating the shanks 32, thus with danger of accident for a person casually staying on the platform in same moment
  • the opening of the hatches is associated with a signal constituted by flags 33 which are projecting from the car shape, as shown in fig. 1 and 3, when the fever mechanisms for driving the hatches have been removed from their safety block position.
  • the closing position in fact, wherein the hooks 9, 9a lock the hatches, as shown in fig. 3, presents the rotation axis of the rocker 2 1 placed on the action axis of the connecting rods 22, 23 coupling the corresponding linking axes of the connecting rod itself with the rocker 2 1 and the arms 24.
  • the signalling flags 33 are carried by the supports 34 swivelling about the pivots 35; the supports 34 are also fitted with levers 36, one of which is connected with a staff . 37, hinged to a heavy block 38, which is swivelling about the pivot 39.
  • a connecting rod 40 joins the ends of the levers 36, thus enabling a joined movement of the two flags 33 at both sides of the car.
  • the shafts 10 carry, in correspondence to the extremities of the hatches 6, 7, the shaped arms 43, having an end roller 44 suitable to act against the sliding blocks 45 linked to the flanks of the hatches 6, 7.
  • the shaft 55 is carried by the bush support 56 and is connected at its end with the cardanic shaft 14.
  • the bilateral coupling element 53 may be brought into the position of engagement with the frontal coupling 4 6 or with the frontal coupling 54, or maintained in a middle position, or "idle” position, through the lever 57 having three fixed stop positions which may be disengaged through the knob 58, as shown by dash-and-dot line in figure 7.
  • the selector 1 3 keeps the shaft 55 and the gear wheel 1 5 separated and independent; in this way, it is not possible that, in case of seizing of the self-lubricating bushes supporting the rotary elements, a non selected couple of hatches is also brought into rotation, as it would occur if the gear 15 were supported by bushes placed directly on the shaft 51, in case of seizing and blocking of the bushes.
  • the opening limiting rods 26, hinged at one end of the car structure, present a curvilinear shape; such a shape serves to establish a free space between the car wall and the surface of the rod 26 which is substantially larger than the maximum size of the transported material; this to the aim of assuring that possible material deposited on the surface of the rods may not remain closed, during unloading, between the same and the car, thus hindering a complete closing movement of the hatches.
  • a curvilinear conformation for the same above mentioned purpose, is provided for the arms 24 too, which, as they are also located in the area subject to material flowing, have not to be in condition of holding back some material against the car wall, what would hinder the hooks 9, 9a from their complete closing movement causing the clamp of the hatches.
  • the opening mechanism according to the present invention proves to be especially safe and reliable, besides economically convenient, since the transmissions and selection of the hatches to be opened are carried out at high speed, upstream to the reduction gears and consequently with low driving torques.
  • the car structure may be built according to the known art; it has, therefore, not to be described here in detail.
