Definitions

  • An apparatus for locking an anode shaft into a transport frame comprising an idler wheel mounted for rotation on the transport frame, an eccentric wheel mounted for rotation on the transport frame in the same horizontal plane and opposite the idler wheel, and a stop plate fixedly attached to the eccentric wheel.
  • This invention relates to a locking device or mechanism which enables a carbon anode, as used in aluminum reduction cells, to be securely locked into an anode transport frame.
  • electrically conductive carbon anodes composed of calcined petroleum coke aggregate and coal tar pitch binder are attached to metal shfts which are used in the pot-line operation.
  • the shaft with an anode block attached is commonly placed on a frame for storage "or for transport to various areas of the operation.
  • the present method of locking an anode shaft into a transport frame requires numerous, bulky, mechanically complex devices to secure the shaft into position.
  • Prior art anode transport frame locking devices generally consist of a complex arrangement of sprockets and levers which activate a locking mechanism having brake shoes with substantially smooth or serrated linings, or serrated metal plates which hold the anode shaft in position.
  • These prior art locking devices are awkward and time consuming to activate, and the many moving parts require frequent maintenance.
  • the brake shoe or serrated metal plates frequently do not exert enough pressure to securely hold the anode shaft, resulting in anodes slipping or dropping, thereby causing damage to the anode, transport frame, and/or nearby machinery.
  • One object of this invention is to provide an improved apparatus which more readily and with less complexity locks an anode shaft into position in an anode transport frame.
  • Another object of this invention is to provide a less time consuming, more eificient apparatus for transporting carbon anodes.
  • FIG. 1 is a frontal elevation view of the anode transport frame and locking device.
  • FIG. 2 is an end view of the cam device.
  • FIG. 3 is a frontal view of the cam device showing the stop plate and counter balance.
  • FIG. 4 is a sectioned view of the cam device.
  • FIG. 5 shows the shaft which anchors the cam device for rotation.
  • idler wheel 12 and cam device 13 are mounted for rotation on opposite sides 'of a space for an anode shaft, 24, in the same horizontal plane on anode transport frame 11.
  • a carbon anode block, 25, has indentions, 27, in its upper surface.
  • Anode shaft 24 is attached to anode block 25 at indentions 27 by means of molten cast iron, babbit, or the like, 28, being poured into indentions 27 around the lower ends of shaft 24 and being allowed to solidify.
  • a handle, 14, and cable or chain, 26, are movably attached to anode transport frame 11 and cam device 13 in the vertical plane above the cam.
  • FIG. 2 which shows cam device 13 in more detail, with anode shaft 24 removed for clarity, stop plate 18 is fixedly attached to eccentric wheel 19.
  • Eccentric wheel 19 is mounted for rotation on shaft 15.
  • Spacer 16 and bearing 17 are mounted on shaft 15 and allow eccentric wheel 19 to rotate with excessive friction.
  • FIG. 3 shows eccentric wheel 19 with stop plate 18 and counter balance 20 attached thereto.
  • a bushing, 21, is mounted between shaft 15 and eccentric wheel 19.
  • FIG. 4 the sectional view shows eccentric wheel 19 with stop plate 18 and counter balance 20 attached; shaft 15 has been removed and is shown inFIG. 5.
  • Bushing 21 extends through stop plate 18 and eccentric wheel 19.
  • a grease groove, 22, forms a circumferential groove in bushing 21.
  • FIG. 5 shows shaft 15 having interior grease passageway 23.
  • eccentric wheel 19 is mounted on anode transport frame 11 adjacent the resting position for anode shaft 24.
  • a rectangular stop plate, 18, with beveled edges is mounted onto the eccentric wheel such that when the wheel. is turned the stop plate rotates with it.
  • stop plate 18 passes in front of the frontal portion of anode shaft 24, as viewed in FIG. 1, thereby preventing forward movement of the shaft (i.e. towards the viewer in FIG. 1).
  • the distance between eccentric wheel 19 and shaft 24 is of such a tolerance that when engaged, wheel 19 exerts suflicient pressure against the shaft to prevent further downward movement.
  • Counter balance 20 is attached to eccentric wheel 19 in a position such that the distance between wheel 19 and wheel 12 is the greatest when the counter balance is at its lowest position, as shown in FIG. 1.
  • the counter balance retains the locking device in an open position when no anode is in the transport frame.
  • One end of cable 26 is attached to counter balance 20 which is welded to the side of eccentric wheel 19 opposite the anode shaft.
  • the other end of the cable has a handle, 14, attached thereto by which one can manually pull counter balance 20 and thereby cause eccentric wheel 19 to move on its axle shaft 15, into a position where it touches anode shaft 24 thereby activating the locking device.
  • eccentric wheel As anode shaft 24 lowers into the transport frame, the eccentric wheel progressively exerts increased pressure on the shaft, thereby halting its downward movement and locking the shaft into place.
  • handle 14 When the eccentric wheel is in an open position handle 14 is placed in a rest position above the wheel, as shown in FIG. 1.
  • idler wheel 12 which prevents the shaft from scraping against the side of the transport frame.
  • the idler wheel freely rotates to the right or left correspondingly to the movement of the anode shaft as the latter is being put into or taken out of transport frame 11.
  • Spacer 16 and bearing 17 allow eccentric wheel 19 to rotate without excessive friction between the wheel and transport frame.
  • a bushing, 21, between eccentric wheel 19 and shaft 15 contains a grease groove, 22, for lubrication.
  • Shaft 15 contains a grease passageway, 23, whereby grease is directed to the groove in the bushing.
  • Apparatus for transporting an electrically conductive anode shaft comprising a transport frame having an idler wheel roatably mounted thereon, an eccentric wheel mounted on said frame and horizontally spaced from said idler wheel so as to be adapted to receive a vertically disposed anode shaft therebetween, a stop plate fixedly attached to said eccentric wheel and rotatable therewith in a plane perpendicular to the axis of rotation thereof, said stop plate extending beyond the periphery of said eccentric wheel, means for rotating said eccentric wheel to grippingly engage an anode shaft disposed between said eccentric wheel and said idler wheel, and said stop plate extending toward said idler wheel and in spaced relation from a portion of said frame to limit movement of an anode shaft received therebetween when grippingly engaged between said eccentric wheel and said idler wheel.
  • Apparatus as defined in claim 1 including a counter balance fixedly attached to said eccentric wheel in a position such that the radius of said eccentric wheel is smallest in the direction of said idler wheel when said counter balance is at its lowest position.
  • Apparatus as defined in claim 2 wherein said means for rotating includes a chain attached at one end to said counter balance and at the other end to a handle such that said counter balance can be raised and said eccentric wheel rotated by lifting said chain.
  • Apparatus as defined in claim 4 including a bushing having a grease groove mounted between said shaft and said eccentric wheel.
