Definitions
- the invention relates to a device for controlling the hopper hatches of wagons and to the hopper wagons and wagons which are provided with them.
- the device object of the invention, is intended to control the hatches only during these latter stages of controlling their closure.
- a result which the invention aims to obtain is a device for controlling hatch hopper doors of wagons, during the phases of controlling the closing of said hatches, which can be used for controlling a single hatch and therefore does not bind maintaining the doors to a synchronization of the movements of at least two doors.
- Another result which the invention aims to obtain is such a device in which the means for holding the doors does not risk releasing the doors in the event of an impact.
- the means for holding the hatch in the open position is chosen of a type such that its holding action can be annihilated by an oscillation d 'a part, and that on the one hand, to release the hatches, it makes this oscillation of the part necessary while, on the other hand, when it returns to the holding position, it guides the return of said part by waiting position for the subsequent release command.
- the wagon 1 comprises, at a certain distance above the rails 2, a chassis 3 carrying at least one hopper 4 (fig 1 and 2) whose base has at least one mouth 5 it even provided with at least one hatch 6 articulated around an axis 7 fixed in space relative to the chassis 3.
- This system 8 consists for example of an oleopneumatic accumulator 8, consisting of a hydraulic cylinder 9 whose end of the rod 10 of the piston is articulated around an axis 11 carried by a lever such as an ear 12 secured to the hatch 6 while the base of the cylinder 13 is articulated around an axis 14 carried by a lug 15 secured to the chassis 3.
- an oleopneumatic accumulator 8 consisting of a hydraulic cylinder 9 whose end of the rod 10 of the piston is articulated around an axis 11 carried by a lever such as an ear 12 secured to the hatch 6 while the base of the cylinder 13 is articulated around an axis 14 carried by a lug 15 secured to the chassis 3.
- a closed reservoir 16 At the base of the cylinder is connected a closed reservoir 16, which a flexible membrane 17 splits into two parts 18 and 19.
- One 18 of these two parts is connected to the cylinder 13 of cylinder 9, while the other 19 is filled with compressed air.
- the holding means 20 which comprises the device for controlling its closure
- the pressure of the compressed air drives the oil into the cylinder where it pushes back the piston whose rod 10 acts on the ear 12 to close the hatch 6.
- the means 20 for holding the hatch 6 in the open position is chosen of a type such that its holding action can be annihilated by an oscillation of a part 22 and that, on the one hand , to release the hatch, it makes this oscillation of the part 22 necessary, while, on the other hand, when it returns to the holding position it guides the return of this part 22 to the waiting position for the subsequent command of release.
- This part 22 which is part of the means 21 for releasing the hatches consists, for example, of one end of one of the arms of a pendulum, 23 of which the end of another arm is grasped by the axis 24 of one end. of a rod 25 while by its part towards which the two arms converge this pendulum is articulated around an axis 26 fixed in space with respect to the chassis and, for example carried by a lug 27 welded on this chassis.
- the rod 25 forms with the arm a non-flat angle, preferably between thirty and one hundred and fifty degrees.
- the rod 25 is grasped by an axis 28 carried by a lever 29 articulated around an axis 30 fixed in space relative to the chassis and for example carried by a lug 31 welded to this chassis.
- the rod 25 and the lever 29 are in maximum elongation and, in the other direction, the compressive stress received from the balance being devoid of transverse component capable of causing the rod and the lever to oscillate, it will remain without effect on the articulated assembly formed by the lever 29 and the rod 25, located one after the other.
- a pendulum 32 is provided and, on the other hand, on the path of the wagon is fixed relative to the track a stop 33 which is situated at a height such that it will not be struck by the pendulum until the hatch is in the open position.
- the pendulum 32 is associated with the lever 29 so that, when the hatch 6 is kept in the open position, the said pendulum 32 is at least substantially vertical.
- the means 20 for holding the hatch can be of any known type such that its action can be annihilated by the oscillation of the part 22 and that, on the one hand, to release the hatch, it makes this oscillation of the part 22 necessary, while, on the other hand, when it returns to the holding position, it guides the return of this part 22 to the waiting position for the subsequent release command .
- This connecting rod must of course be incompressible to allow it to resist if necessary the action of the member 8 for controlling the closure.
- this connecting rod 34 may consist, in particular, of a tubular body 37 closed at one end by a base 38 and provided at the other end with two ears 39 forming a joint yoke.
- the base 38 is pierced in its axis with a cylindrical hole 40 to allow the sliding of a rod 41 completed, on the external side, by a yoke 42 and, on the other side, by a threaded part 43.
- a spring 44 is mounted inside the body around the rod carrying the yoke. This spring 44 is prestressed by means of a nut 45 and a ring 46 which produces a guide piece inside the tubular body 37.
- the device comprises means ensuring that the release of the hatch cannot be obtained only by oscillation of the part 22 in one direction, as is the case, for example, with the control of the balance 23 exposed above.
- the means 20 for holding the hatch 6 in the open position comprises, linked in rotation with the hatch 6, a ramp 49 (FIGS. 7 and 8) for example carried by the fields of the ear 12 on which acts the member 8 for controlling the opening of the hatch.
- This ramp 49 guides the end of the part 22, the oscillation of which controls the release of the hatch.
- a roller 50 is fixed to the end of said part 22.
- a spring 51 constantly keeps the roller 50 in abutment on the ramp 49 which in turn has a notch 52 in which the roller 50 falls when the hatch 6 is in the open position.
