Definitions

  • the present invention relates to hopper wagons for the bulk transport of heavy products such as ore, coal, coke, cereals or the like and relates more particularly to the problem of the automatic control of opening and closing of the side hatches of emptying of these cars.
  • the opening is in an oblique plane, it is necessary to have a closing mechanism which exerts a traction on the hatch to bring it back against the opening which it must observe; if the opening is in a vertical plane, the hatch is already in the closed position in front of the opening which it must close and it then suffices to close the lock.
  • German patents 316,537; 1,206,005 and French patent 1,424,100 there have been described devices for controlling the opening and closing of the hatches constituted by a linkage comprising a connecting rod coupled to each hatch, this connecting rod lifting the hatch and keeping it open and then ensuring a traction on the hatch to ensure closure.
  • a linkage comprising a connecting rod coupled to each hatch, this connecting rod lifting the hatch and keeping it open and then ensuring a traction on the hatch to ensure closure.
  • the thrust exerted on the doors by the products during opening causes large and brutal pulls on these mechanisms which deteriorate rapidly.
  • the present invention relates to an opening and closing control mechanism which has the advantage of being extremely simple and is therefore inexpensive and very reliable.
  • the mechanism according to the present invention is characterized in that it is constituted by: a tilting cam provided with a lever, said cam tilting around a fixed axis; a jack pivotally mounted about a second fixed axis; said tilting cam and said cylinder being coupled one to the other the other by an intermediate connecting rod carrying a pin engaging in a fixed locking part; so that a push of the hydraulic cylinder lifts the intermediate rod by releasing the pin from its lock, rocking the closing cam to release the hatch and then bringing the lever of said cam to the standby position for blocking open door, in which the hatch comes to bear against said lever.
  • the hopper wagon which is not shown, has a drain orifice 1 to which the material is brought by an inclined bottom 2.
  • the orifice 1 is located in a practically vertical plane and is closed by a hatch 3 which is articulated to a horizontal pivot axis 4.
  • the hatch 3 is locked in the closed position by a cam 5 which pivots about a horizontal axis 6, which is carried by the chassis of the wagon and is therefore fixed.
  • the cam 5 is integral with a lever 7 which is located on the side of the opening 1 and which extends upwards.
  • a lever 8 on the lever 7 which carries an axis 9; on this axis 9 is pivotally mounted an intermediate connecting rod 10 which carries a journal 11.
  • said intermediate connecting rod 10 is articulated, by an axis 12, at the end of the rod of a jack 13, which itself even is pivotally mounted on an axis 14 carried by a support 15 which is fixed to the chassis of the wagon.
  • a locking piece 16 is also fixed to the chassis by a support 17. This locking piece comprises an ascending ramp 16a which leads to a shoulder 16b.
  • the intermediate connecting rod 10 and the actuator 13 have lengths such that the straight line joining the axes 9 and 12 made with the straight line joining the axes 14 and 12 an angle of approximately 150 ° open downwards.
  • the hatch 3 is provided on the side with a lateral tab 3a, which projects from the side.
  • the hatch pivots down around its axis 4 until the tab 3a comes to bear against the end of the lever 7 which constitutes a forestay which keeps the hatch 3 in the open position. (The jack 13 then makes an angle of 19 ° with the horizontal).
  • the support 17 comprises a horizontal plate 18 against which the end of the rod slides. cylinder 13.
  • the end of said connecting rod 10 has a spout 19 provided with a planar end 20 which, when the lever pivots about the axis 9 abuts against a support plate 21 disposed at the base of the tab 8.
  • the hydraulic circuit can be of any suitable type, but preferably the cylinder 13 includes an accumulator 22 which, when the supply to the cylinder 13 is interrupted, at the end of the locking operation after closing, maintains a residual pressure by residual pressure. the intermediate connecting rod 10 in order to maintain the pin in the bottom of the shoulder 16b, which constitutes additional security.
  • This type of control can be carried out by one or two sets per hatch depending on the flexibility of the hatch.
  • the support 15 and the support 17 with its sliding plate 18 are mounted on a cross member 23 which is fixed to the wagon; so that the whole mechanism is carried by this single cross member and constitutes an assembly which can be sold separately to equip the wagons which one wants to modernize.
