Definitions

  • a wagon for charging coal into a coke oven is provided with a horizontally displaceable traverse on which a vertically displaceable pickup head is mounted. This head is engageable with a cover on an opening in a coke oven to lift off this cover, then displace it laterally out of the way so as to permit filling of the oven through the opening.
  • a T-shaped lever has one arm pivoted to the lower end of a vertically displaceable rod slidingly guided on the traverse.
  • the T-let of this lever carries a feeler rod extending parallel to the displacement direction of the traverse and engageable with a cover when it is seized by the pickup head.
  • a switch coacting with the upper end of this rod is operated only when the feeler engages a cover on the pickup head, in the raised position of this pickup head, so as to indicate to the discharge mechanism of the filling wagon that the cover is indeed removed from the filling opening.
  • the present invention relates to an apparatus for removing the cover of a coke-oven opening and for charging same with coal; more, particularly the invention relates to an arrangement for this purpose which includes a sensor for indicating that the cover has properly been removed.
  • Another object is the provision of such an apparatus which automatically ascertains if the cover or plug has been removed from the filling hole and is indeed supported by the pickup, even if this cover or plug is not positioned exactly in the center of the pickup.
  • This rod is engageable with a switch and the lever carries a feeler which is engageable with the cover when it is picked up by the pickup element.
  • the lever is T-shaped, having the end of one T-arm pivoted on the pickup about a horizontal axis parallel to the displacement direction of the traverse, the end of the other T-arm pivoted on the lower end of the control rod, and the end of the T-leg carrying the feeler.
  • the rod is downwardly biased by a spring compressed between an abutment on the rod and the guide on the traverse.
  • FIG. 1 is a side view of the apparatus according to the present invention.
  • FIG. 2 is a top view of the apparatus of this invention.
  • FIGS. 3 5 are views of the apparatus in the direction of arrow III of FIG. 1 showing the apparatus in different positions;
  • FIG. 6 is a top sectional view of an alternative embodiment of the present invention.
  • a coke-oven filling wagon l is horizontally displaceable over the top 24 of a coke oven formed with a plurality of filling openings 23.
  • This wagon 1 is formed with a downwardly directed funnel 2 which can pour a charge of coke through a telescoping filling tube 25 into any of the holes 23.
  • the wagon 1 is provided with parallel horizontal rails 9 in which ride rollers 8 carried on a traverse 3 which can be displaced back and forth on these rails relative to the carriage of the wagon 1 by means of a hydraulic cylinder shown partially at 26.
  • a hydraulic cylinder shown partially at 26 Vertically displaceable on the traverse 3 is an assembly 4 having rails 11 engaging rollers 10 on this traverse 3.
  • the assembly 4 is provided with a pickup head 5 having an electromagnet 6 supplementing a mechanical grab 27 for lifting a plug 13 from one of the holes 23.
  • This mechanical grab 27 comprises a motor 28 connected through a threaded spindle 29 to a hook 30 or the like such that operation of the motor mechanically engages the top of a cap 13 with the hook.
  • a cylinder 12 carried on the traverse 3 raises and lowers the pickup assembly 4 relative to this traverse 3, lifting with it the cover 13, whereupon the cylinder 26 serves to pull the entire traverse 3 to the left, as seen in FIG. 1 and allow the coke to be poured into the oven.
  • a T-shaped lever 15 has one arm 19 pivoted on the head about a horizontal axis A parallel to the displacement direction of the traverse 3 and another arm 20 pivoted on the lower end of a control rod 16 vertically slidable in a guide 22 carried on the traverse 3.
  • the T-leg 21 of this lever is provided with a feeler rod 14 which extends along the head 6 underneath it and parallel to the axis.
  • the upper end of the rod 16 carries a switch-actuating block 31 which operates a control switch 17 carried on the traverse 3.
  • a spring 18 is compressed between a snap ring 32 on the rod 16 and the guide 22 so as to urge the rod 16 downwardly, although in any case the weight of this rod would pull it downwardly to a limited extent.
  • the block 31 does not engage the switch 17 and actuate it.
  • the feeler is pivoted completely out of the way to the side and the rod 16 is pushed all the way down by the spring 16.
  • the feeler rotates around and comes into contact with the bottom of the magnet 6, again allowing the spring 18 to pull the rod all the way down.
  • An apparatus for filling a furnace having a filling hole blocked by a cover comprising:
  • pickup means on said traverse displaceable between an upper position and a lower position and engageable in said lower position with said cover on said hole for seizing and lifting said cover from said hole;
  • a guide on said traverse receiving said rod and permitting vertical displacement thereof relative to said traverse;
