Definitions

  • the present invention relates to a pocket wagon intended for the transport of liquid pig iron, said pocket wagon being provided with a device for continuously weighing the transported pig iron.
  • the pocket on the one hand, the bogies on the other hand, must have relative to each other the possibility of any relative displacement of small amplitude. This is why the connection between the pocket and the bogies is generally effected by ball joints.
  • the installations are such that the visibility in the pocket is extremely reduced because it is very difficult to see the effective level of cast iron inside a horizontal cylinder through an orifice from which sparks and fumes exit.
  • pocket transport devices are equipped equipped with a device for weighing the transported pocket, but this is obviously not not pocket wagons, the only ones concerned by the invention.
  • the present invention makes it possible to solve these problems in a particularly simple manner.
  • the pocket wagon of the invention provides that at least one of the pocket support devices at each of its two ends is constituted by a vertical piston jack having, with respect to its vertical body, sufficient play to allow it to perform ball joint movements, said cylinder being equipped with a device for weighing the pocket by measuring the pressure of the fluid it contains.
  • the tip 2 of the pocket 1 is encircled at its end with a bandage 3 carried by rollers 4 mounted swivel in an intermediate chassis 5.
  • This chassis intermediate rests on the chassis 7 carried by the bogies 8 by means of a device 9, which will be described below and which simultaneously plays the role of ball and weighing device for the bag 1.
  • stops 6 limit the possibilities of tilting of the pocket 1 relative to the chassis 7.
  • the chassis 7 carries, by means of friction pads 10, a vertical body of the actuator 11 of low height in which slides a vertical piston 12 fitted in the intermediate chassis 5.
  • the seal is ensured by a seal 13 held by a flange 14, and the piston 12 has, relative to the body 11, a clearance j of the order of a millimeter allowing it to effect movements of the ball joint.
  • a line 16 connects the interior space of the jack containing the grease 15 to a device 17 for measuring the pressure in this space.
  • the device 17 is a pressure sensor which can be either direct display or connected to a traditional information processing chain.
  • the jack of the invention is moreover equipped with four connecting rods 18 which connect, by means of ball joints 19, 20 and shouldered axes 21, 22, the piston 12 to the body 11, these connecting rods being horizontal and having the role of maintaining the piston 12 and the body 11 strictly coaxial, which avoids masting of the internal wall of the body 11 and prevents friction from 12 into 11 which improves the accuracy of the weight measurements.
  • FIG. 5 represents a variant of the ball joint of FIG. 3 in which the connecting rod device 18 is replaced by a ball joint 23 connecting the piston 12 to the body 11, the axial parts of these being produced respectively in female and male form as shown in the drawing.
  • the space containing the grease 15 then consists of two parts separated by the ball 23 and connected by a pipe 24.
