Definitions

  • This invention relates to a spotting device for use with rail traveling machines and, more particularly, to a spotting device for accurately positioning coke oven machines with respect to a selected coke oven of a coke oven battery.
  • auxiliary coke oven equipment In conventional coke oven operations some auxiliary coke oven equipment or machinery must be accurately positioned and aligned with respect to a particular coke oven of the battery for the proper functioning of such equipment.
  • auxiliary coke oven equipment includes, for example, larry cars for charging coal into a coke oven and pusher machines for pushing hot coke from the coke oven.
  • a machine spotting device for accurately positioning a-machine that travels over rails with respect to a preselected position along such rails comprises a plurality of indexing surfaces that are remote from and run along the length of the rails. Each indexing surface corresponds to each position to which the machine is to be spotted.
  • a machine moving means is provided for engaging the indexing surfaces and moving the machine a predetermined spaced distance from the indexing surface to the preselected position.
  • a means being pivotally mounted to the machine is provided for carrying the machine moving means and placing the machine moving means into operative association with the indexing surfaces.
  • FIG. 1 is an elevational, schematic view of an embodiment of a machine spotting device mounted to a conventional'larry car made in accordance with the invention.
  • FIG. 2 is a side cross-sectional view of the machine spotting device of FIG. 1 taken at line [1-1].
  • a coke oven 11 which is a part of a coke oven battery has a conventional larry car 13 traveling on wheels 16 along rails that extend over the roof of the coke oven battery.
  • the larry car 13 has a spotting device 17 made in accordance with the invention that is suspended underneath the superstructure 14 of the larry car 13.
  • the larry car 13 moving along rails 15 receives coal from a conventional coal bunker (not shown) into its hoppers l9 and, after the larry car 13 has been aligned with the selected coke oven, discharges the coal from the hoppers 19 into the coke oven through conventional coke oven ports 21. After the coal has been discharged into the coke oven, the larry car 13 returns to the coal bunker to receive a fresh supply of coal.
  • a conventional rack 23 runs along the length of the battery from end to end and is fixed thereto by fasteners or the like.
  • the rack 23 has relatively wide interdental spaces 25 at spaced intervals along the rack 23.
  • Each interdental space 25 corresponds to each coke oven of the battery and has a width sufficient to receive the machine spotting device 17.
  • Each interdental space 25 provides an indexing surface 27 and an oppositely spaced backstop surface 29 as shown in FIG. 2.
  • These surfaces 27 and 29 are planar surfaces that are generally perpendicular to the direction of travel of the larry car 13.
  • Each indexing surface 27 and each backstop surface 29 corresponds to each coke oven of the battery, and in every case, the distance between the indexing surfaces 27 and the backstop surfaces 29 of each space 25 is equivalent.
  • each backstop surface 29 is aligned with the centerline of each coke oven.
  • the position of the indexing surface 27 or of the backstop surface 29 with respect to the coke oven will depend upon the position of the spotting device 17 with respect to the charging hoppers of the larry car.
  • the machine spotting device 17 includes an indexing cylinder 31, as shown in FIG. 2, which has a plunger 33 that is engageable with the indexing surface 27.
  • the indexing cylinder 31 is mounted to one end of arm 35 which is pivotally mounted to the larry car 13 with pivots 37 at its other end.
  • the direction in which the arm 35 pivots is substantially at right angles or perpendicular to the direction of travel of the larry car.
  • an arm moving cylinder 39 for pivoting the arm 35 on its pivots 37 from its disengaged, carrying position (illustrated in phantom lines in FIG. 1) into its'engaged, operating position (illustrated in solid lines in FIG. 1).
  • the cylinder 39 is pivotally mounted to the larry car 13 with pivots 41 and to the arm 35 with pivots 43.
  • the arm 35 and its indexing cylinder 31 is carried under neath the superstructure 14 of the larry car in the disengaged position without interfering with the travel of the larry car 13 to and from selected coke ovens and is dropped into the engaged position when the larry car is to be spotted with respect to a selected coke oven.
  • indexing cylinder 31 and arm moving cylinder 39 illustrated herein are conventional and are commercially available. Hydraulic electrical, pneumatic cylinders and the like may be used in accordance with the invention.
  • the cylinder 31 When the indexing cylinder 31 is lowered into the engaged operating position (illustrated in solid lines in FIG. 1) the cylinder 31 is actuated and plunger 33 first engages the indexing surface 27.
  • the indexing surface 27 serves as a reference point for the larry car.
  • the larry car 13 After the plunger engages the indexing surface, the larry car 13 begins to move away from the indexing surface due to the action of the cylinder 31 until the plunger 33 has extended its full stroke whereupon the back end 32 of cylinder 31 engages the backstop surface 29. Then the cylinder 31 engages the backstop surface 29 and the larry car is accurately aligned with the coke oven and cannot travel further with respect to the coke until the indexing cylinder 31 is raised to its disengaged position.
  • FIG. 1 a first limit switch 45 which is actuated by the movement of arm 35 and which prevents the actuation of the indexing cylinder 31 until the arm 35 is moved to the engaged position (shown in solid lines in FIG. 1) whereupon the limit switch 45 allows the indexing cylinder 31 to be actuated.
  • a second limit switch 47 which is, also, actuated by the movement of arm 35 and which prevents the driving mechanism (not shown) of the larry car 13 from operating until the arm 35 is moved to its disengaged position (shown in phantom lines in FIG. I).
  • FIG. 2 there is provided shims 49 which are used to adjust the position of the backstop surface 29 due to variations and changes in the alignment of the backstop surfaces 29 with respect to the coke oven. Such changes will occur due to conventional thermal expansion and contraction of the coke oven battery.
  • the larry car 13 In operation the larry car 13 is loaded with coal at coal bunker (not shown) and travels therefrom to a selected coke oven over rails 15. During this travel the arm 35 and the indexing cylinder 31 are disposed in the disengaged carrying position. The second limit switch 47 is engaged allowing the driving mechanism of the larry car to move the larry car therealong on rails 15. The driving mechanism of the larry car 13 is stopped in the near vicinity of the coke oven which is to be charged by the operator in a conventional manner. The arm moving cylinder 39 is actuated by the operator and it pivots the arm 35 and the indexing cylinder 31 into operative association with the interdental space 25 for the selected coke oven as shown in solid lines in FIG. 1 and as shown in FIG. 2.
  • the second limit switch 47 is thereby released and prevents the driving mechanism (not shown) of the larry car 13 from operating so that only the indexing cylinder 31 may advance the larry car 13 to its preselected position in accordance with the invention.
  • the first limit switch 45 is actuated allowing the indexing cylinder 31 to be actuated at will.
  • the indexing cylinder 31 is actuated by the operator of the larry car in a conventional manner and thereupon plunger 33 engages the indexing surface 27 in FIG. 2 and urges the larry car 13 away from the indexing surface.
  • the indexing cylinder 31 and the larry car 13 are now moved until the back 32 of the indexing cylinder engages the backstop surface 29 whereupon the larry car 13 is perfectly aligned with its coke oven.
  • the coal in the hoppers 19 of the larry car 13 is discharged into the coke oven in a conventional manner.
  • the indexing cylinder 31 is released, its plunger 33 is withdrawn and the arm moving cylinder 39 returns the arm 35 to the disengaged position (in phantom lines in FIG. 1).
  • the second limit switch 47 thereby is actuated and permits the driving mechanism (not shown) of the larry car to advance the larry car 13 along rails to the coal bunker (not shown) to receive another charge of coal to be charged into another coke oven.
  • the first limit switch 45 is released preventing the indexing cylinder 31 from being actuated.
  • Apparatus for positioning a machine travelling over rails on a supporting surface with respect to a preselected location along said rails comprising:
  • each protrusion having opposite indexing and back-stop surfaces, said protrusions being separated by interdental spaces;
  • the apparatus of claim 1 including:
  • Apparatus for positioning a machine travelling over rails on a supporting surface with respect to a preselected location along said rails comprising:
  • each protrusion having opposite indexing and back-stop surfaces and with said protrusions separated by interdental spaces;
