Definitions

  • the subject of the present invention is a device for locking hoppers for unloading hoppers, in particular hoppers for railway wagons.
  • Hoppers intended to contain powdery bulk products such as ores, coke, coal, cereals, etc. are generally provided along their median longitudinal plane with two symmetrical inclined planes directed outwards; which form what is called a "donkey", these inclined planes opening into orifices which are closed by panels which are called hatches which are in oblique planes. These hatches can be sliding or articulated so that they can be opened to let the product flow out of the wagon on both sides of the speed bump.
  • the present invention relates to a device such that, after opening, there is, automatically, a separation of the rotary control member and rods control the hatches; so that the latter can fight freely.
  • the present invention relates to a mechanism allowing the opening and closing of this type of hatches, the closed position being freestanding by passing the linkage past a neutral point.
  • the present invention relates to a device for controlling the opening and closing of side doors of hopper wagons by a central control of the type in which said doors are articulated by their upper side around a horizontal axis parallel to the longitudinal axis of the wagon and each controlled by a rod connected at its end to a curved gooseneck lever coupled to a rotary control member so that said control lever when it is rotated exerts on the rod a pulling movement or of thrust pivoting the hatches, the rotary movement for closing extending beyond the closing dead center so that the position of the rods is freestanding, characterized in that the coupling of the swan neck lever to the the rotary control member is made by means of a notch, located at the end of a rotary lever, in which a roller located at the end of the neck lever engages swan, the wagon chassis carrying a fixed part comprising a groove placed on the circular path traversed by the notch during the closing movement so that said roller leaves the notch to engage in the groove, which allows the hatches to freely struggle after
  • the device according to the invention preferably includes the following arrangements: - the rotary lever is hydraulically controlled, - the rotary lever comprises two symmetrical arms for simultaneously controlling two doors located symmetrically on each side of the speed bump, - each door is provided at its base with an auxiliary locking mechanism in the closed position.
  • FIG. 1 represents a hopper wagon with bi-lateral unloading of known type comprising a hopper 1 provided at the base of its two lateral sides with hatches 2; the wagon traveling by means of wheels 3 on a railway track 4.
  • this wagon has along its median longitudinal axis a donkey 5, consisting of two symmetrical inclined planes 5a, 5b which guide the material, contained in the hopper 1, doors 2 which are eight in number, in the example shown; they can be four.
  • the wagon comprises two pairs of rods 6, 7, each pair, located at one end of the wagon, simultaneously opening four hatches 2 (two on each side).
  • the wagon has four pairs of rods 6, 7, 8, 9, two pairs 6, 7 being located at the ends of the wagon and two pairs 8, 9 in the center, each pair simultaneously opening two 2 opposite hatches (one on each side).
  • the door 2 closing mechanism is shown in FIGS. 4 to 7 where it is designated by the general reference 10.
  • each of the hatches 2 is controlled by a rod 6 (the hatch 2a by the rod 6a and the hatch 2b by the rod 6b) each hatch 2 being mounted with free pivoting on an axis 11 ( 11a, 11b) horizontal and parallel to the longitudinal axis of the wagon.
  • the rod 6a pivotally connected to the hatch 2a, is provided, at its other end, with a curved piece 12a, in the form of a swan neck at the end of which is a roller 13a.
  • this roller 13a is housed in a notch 14a disposed at the end of a rotary lever 15a by a shaft 16 of which it is integral.
  • the curved part 12a bypasses said shaft 16 by passing over it.
  • the rod 6b pivotally connected to the hatch 2b, is provided with a curved part 12b comprising a roller 13b, housed in a notch 14b, disposed at the end of a rotary lever 15b carried by said shaft 16 with which he is attached.
  • the curved part 12b bypasses the shaft 16 from below.
  • the shaft 16 is integral with a crank 17 articulated by a pin 18 at the end of the rod 19 of a hydraulic cylinder 20.
  • the chassis of the wagon carries two parts 21a and 21b which are fixed; the part 21a having a groove 22a and the part 21b a groove 22b.
  • the part 21a located above the assembly formed by the shaft 16 and the two levers 15 (15a and 15b) is fixed below the inclined plane 5a of the speed bump 5, while the part 21b, located below said assembly 16-15, is carried by the chassis of the wagon (but this provision is in no way limiting).
  • the grooves 22 (22a and 22b) are open at one of their ends and have a configuration such that their opening intercepts the path of the rollers 13 (13a and 13b).
  • Each hatch 2 (2a, 2b) has at its base a latch 23 (23a, 23b) freely mounted to pivot on an axis 24 (24a, 24b).
  • an axis 25 (25a, 25b) carried by the structure of the wagon.
  • a lever 26 (26a, 26b) carrying a pusher 27 (27a, 27b), each lever 26 being coupled to a rod 28 (28a, 28b).
  • the two rods 28 (28a, 28b) are articulated to a lever 29 rocking around a fixed axis 30, each at one end of said lever. This rocking lever 29 is coupled to the rod 31 of a hydraulic cylinder 32.
  • the shaft 16 To open one and the other hatch, the shaft 16 must be rotated by means of the jack 20 and the crank 17 so that the two rollers 13 pass beyond the two neutral positions defined by the two lines above mentioned. As soon as these two points have passed, the weight of the material contained in the hopper 1 pushes on the doors 2 to open them and they take the maximum open position shown in FIG. 6. In this position, the rod 19 cylinder 20 is in the fully extended position; the levers 15 have pivoted in the opposite direction of the arrow "f", by about 110 °, until the notches 14 are opposite the openings in the grooves 22 and the rollers 13 have left said notches to go into said grooves 22 and this until it stops at the bottom of these grooves, thus limiting the opening movement of the doors 2.
  • the cylinders 20 and 32 can also be of any suitable type: mechanical, electrical, pneumatic or hydraulic. It is only as an example that in the description above, it is indicated that they are hydraulic cylinders.
  • These hydraulic cylinders can be supplied by any known means, but are preferably supplied by a particular hydraulic circuit illustrated in FIGS. 8 to 10.
  • At least one of the wheels 3 of the wagon drives a hydraulic pump 43 which can, advantageously conform to the hydraulic pump described in French patent application 86.00480 filed on January 15, 1986 , said pump being used on all types of axles and not driving special axles.
  • the two jacks 20 and 32 are single-acting jacks comprising an accumulator 39.
  • the two distributors 37 and 38 are connected by a pipe 40 to a reservoir 41 itself connected by a pipe 42 to the pump 43.
  • the pump 43 flows into the accumulator 36 through the pressure regulator 34.
  • the pressure regulator 34 (FIG. 9) simply comprises a non-return valve and a pressure relief valve; when the maximum pressure is reached, the pressure relief valve 44 opens and returns to the reservoir 41, via the pipe 40, the liquid delivered by the pump 43. The journeys made by the wagon being relatively short, the hydraulic liquid has no time to heat up excessively.
