Definitions

  • This invention relates to an installation comprising a cradle for supplying ingots to a rolling mill, the said installation lbeing intended for mounting at a fixed position along the rolling-mill roller table axis in order to cause the ingots transported on ingot trucks to be deposited onto the roller table.
  • the installation enables simplified ingot trucks to be used, which require no depositing elements such as transfer rollers or a cradle, and hence with no driving elements.
  • the installation comprises a rocking cradle attached to an element for controlling twodirectional rocking movements about a horizontal pivot axis, the latter pivot being movable between a bottom position and a top position, and a device for locking and releasing the pivot, said device being controlled by the cradle rocking movements, said device comprising a catch to retain the pivot in its bottom position during the lifting movement of the cradle into a vertical position which brings it beneath the ingot borne by an ingot truck, means for releasing the pivot at the end of said movement for an additional substantially vertical movement to engage the ingot, a catch for retaining the pivot in its top position which it reaches at the end of said movement, during the lowering of the cradle into its position for depositing the ingot, and means for releasing the pivot at the end of this movement, during an additional movement of the cradle into its horizontal inoperative position.
  • FIGURE 1 is a general view of the installation in section along a vertical plane passing through the axis of the roller-table, and showing the cradle in the inoperative position.
  • FIGURE 2 is a partial view showing the cradle at the end of its angular lifting movement.
  • FIGURE 3 is a partial view of the cradle at the end of its ingot-engagement movement.
  • FIGURE 4 is a partial view of the cradle at the end of its angular movement for depositing the ingot.
  • FIGURES 5, 6, 7 and 8 are respectively details of FIG- URES 1, 2, 3 and 4 to an enlarged scale showing the corresponding positions for releasing the cradle pivot.
  • the installation illustrated in FIGURE 1 feeds a roller table 1 on which are deposited the ingots 2 transported by an ingot truck moving on a track 3 in a direction per- See pendicular to the direction of movement of the ingots on the roller table 1.
  • the ingot tnuck may be of any type for the transportation of ingots loaded in an inclined position at varying degrees to the vertical.
  • the ingot truck illustrated comprises a chassis 4 mounted on wheels 5 and having fixed abutments 6 and 7 for an ingot 2, the head of which rests on a lug 8 pivoted at 9; the lug 8 is connected by a pivot 10 to a link 11 provided with resilient means (not shown.) to damp the impacts on loading of an ingot.
  • Levers 14 and 15 are pivotally connected to the chassis 4 at 12 and 13 and their top ends are pivotally connected to a ram 18 at 16 and 1'7.
  • the fixed installation comprises a rocking cradle 19 pivoted about a horizontal axis 20.
  • the cradle comprises two ingot supporting members 21 adapted to be inserted between the rollers 1 of the roller table, one such member bearing on a fixed stop la.
  • the cradle I? is connected to a rack 22 which is pivoted at 23 and driven by a pinion 22a.
  • the pivot 20 is borne by a rocker 24 pivoted about a fixed pivot 25.
  • the cradle 19 bears a roller 26 which is mounted on a pivot 27 and which, when the cradle is in the raised position, is adapted to engage a fixed plate 23 rigidly connected to a fixed frame 29.
  • This frame flso supports a pivot 30 about which rocks a lever 31 connected to a jack 32 and adapted to control the forward movements of the ram 18 mounted on the ingot truck.
  • the pivot 20 of the cradle 19 can occupy two positions as a result of the rocker 24 pivoting about its axis 25.
  • a movatble catch 33 pivoted about a fixed shaft 34 locks the pivot 20 in its bottom position (FIGURE 1) and a movable catch 35 pivoted about a fixed pivot 36 locks the pivot 20 in its top position (FIGURE 3).
  • the function of the catches 33 and 35 will be explained in the following description of the operation of the installation with reference to FIGURES 5 to 8, which are drawn to an enlarged scale.
  • the ram 18 actuated by the jack 32 then pushes the ingot towards the cradle 19 until it bears on the latter (FIGURE 3).
  • the action of the jack 32 is so controlled as to limit the thrust of the ram 18 to a given value and maintain this thnust during the start of the movement of the cradle 19 into the horizontal position for depositing the ingot, so as to avoid any release of the ingot at the start of this movement.
  • a control of this kind can be provided with any known means, e.g., calibrated valves for controlling the pressure of the fluid used in the jack and directly subject to the movements of the cradle, and by stops for the end of the movement and reversal of the direction of operation of the jack.
  • the cradle 19 rotates about the pivot 20 which is locked in the top position by the catch 35.
  • the ingot is deposited on the roller table 1, and a dog 1% 3 borne by the cradle 19 acts on a lug 351) connected to the catch 35, which is then returned to the position for releasing the pivot 20 (FIGURE 8).
  • the cradle 19 is then returned by the rack 22 to the initial bottom position shown in FIGURES 1 and 5, in which it abuts the stop 1a and in which it is again locked by the catch 33.
  • actuation of the rack 22 causes the cradle to be brought beneath the ingot and then engage the same when said rack is moved in one direction, and causes the ingot to be deposited and the cradle to return to the initial position when the rack is actuated in the other direction, the said movements occurring successively and Without any dead time.
  • control rack could be replaced by a hydraulic jack, or else the installation could be adapted to ingot transportation devices other than ingot trucks.
  • An installation comprising a cradle for supplying ingots to a rolling mill, the said installation being disposed between a movable ingot supply device and the rolling mill roller train, characterised in that it comprises a rocking cradle attached to an element for controlling twodirectional rocking movements about a horizontal pivot, said pivot being movable between a bottom position and a top position, and a device for locking and releasing the pivot, said device being controlled by the cradle rocking movements, said device comprising a catch to retain the pivot in its 'bottom position during the lifting movement of the cradle into a vertical position which brings it beneath the ingot borne by an ingot truck, means for releasing the pivot at the end of said movement for an additional substantially vertical movement to engage the ingot, a catch for retaining the pivot in its top position which it reaches at the end of said vertical movement, during the movement of the cradle into its position for depositing the ingot, and means for releasing the pivot at the end of this movement, during an additional movement of the
  • the cradle control element consists of a movable rack attached to the cradle between the base for supporting the ingots and the movable pivot.
