Definitions

  • the invention relates to a device for lifting rammers, which are used in ramming coking plants to compress coking coal before they are introduced into the coke oven, with lifting disk shafts mounted on both sides of the ramming rods in bearing points, which are driven centrally and on which lifting discs which influence the ramming rods in sections are seated.
  • the lifting disks on one side of the ramming device each have a common lifting shaft per tamper wagon, which is driven by a gear.
  • the gears of the two lifting shafts are in turn driven by an electric motor via idler gears and a gear.
  • the bearings of the lifting shafts are screwed to the frame structure and lined with sheet metal packages. To readjust the lifting shafts, the bearings are detached from the frame construction and the lifting shaft with the lifting disks and bearings are lifted off in order to adapt the thickness of the laminated core to the degree of wear of the friction linings and to ensure the frictional force required to lift the tamper again.
  • Adjusting the lifting shafts takes a lot of work and time, although it is usually sufficient to adjust only one of the two lifting shafts.
  • a suitable device e.g. a hoist is required.
  • the lifting disc shaft is generally only readjusted when one or more rammers are no longer raised.
  • slippage occurs due to reduced friction between the tamper bar and the cam of the lifting discs.
  • the stroke of the tamper reduced in this way reduces the tamped density of the coking coal and thus also of the coal cake which is introduced into the furnace for coking.
  • the tamper bars that are not raised are still in the coal cake and are stamped in while the wagon train continues to be moved by means of a hydraulic cylinder. This can lead to bending of the tamping rods stuck in the solidified coal cake. It is then usually not possible to avoid changing the tamper rods.
  • the invention has for its object to provide a device with a constant contact pressure of the lifting discs, which works automatically taking into account the different thicknesses of the webs and friction linings.
  • the lifting disk shafts are individually supported in accordance with the number of tamper rods, the bearing points being designed as interlocking toothed rockers having toothed segments and as such can be acted upon simultaneously and in the same direction via a hydraulic system.
  • the lifting disk according to the invention being mounted between two toothed rockers on the lifting disk shaft, which at the same time carries the lifting shaft pinion.
  • this lifting shaft pinion can be coupled to the motor via a distributor wheel and a drive branch. This makes it possible to drive all the lifting disks with a single motor and thus to lift and drop the individual tamper rods evenly and in the intended cycle.
  • the lifting discs are pressed evenly against the webs of the tamper rods via the toothed rockers.
  • the toothed rockers according to the invention are shifted in pairs in the area of the toothed segments on a lever shaft, one of which via a hinged lever and one Working cylinder movably connected to it can be influenced or rotated. If the lever and thus the lever shaft are adjusted via the working cylinder, this movement is automatically transmitted via the toothed segments from one to the other rocker arm and thus to both lifting discs.
  • the working cylinder can easily maintain the same position of the lever shaft or the rocker arm and the lifting disk or lifting disks, even if it is under load, since the hydraulic working cylinder is assigned a hydraulically unlockable check valve. With this hydraulically unlockable check valve, the oil spring on the piston and on the rod side can be locked without leakage oil.
  • a pressure accumulator is arranged in the feed line upstream of the check valve. This pressure accumulator serves as a pressure buffer, so that a constant pressure is maintained in front of the hydraulically unlockable check valve.
  • Automatic adjustment of the set pressure is advantageously achieved by providing a double pressure switch on the rod side in the control line, which can be influenced via a timing relay and / or a position contact assigned to the lifting disks. If it is determined via the timing relay and the position contact on the lifting disks that the required preload pressure is not reached within the specified time, the double pressure switch is used to readjust and the optimal preload pressure is guaranteed again for the next operation. The double pressure switch is excited via the timing relay and the position contact.
  • the distributor wheel is rotatably arranged on the lever shaft.
  • the distributor wheel or the two distributor wheels can always mesh with each other regardless of the selected pressure and thus the position of the lifting shaft pinion.
  • the invention is characterized in particular by the fact that the hitherto complex adjustment work in the operation of several rammers in one ramming mold is no longer necessary, since the separate storage of the lifting discs and their individual drive now make it possible to press the individual lifting discs to the state of the individual ramming rod to choose accordingly.
  • the advantage of supplying all lifting disks with a single drive is not neglected.
  • the individual tamper rods are acted upon uniformly on both web sides by the lifting disks acting there. This not only ensures smooth and trouble-free operation, but at the same time also a more uniform and always consistent compression of the coal cake over the entire length of the tamp mold.
  • the section shown in FIG. 1 is a partial view of a ramming device with a plurality of rammers 1 working in parallel with one another.
  • Two ramming bars 2, 3 in each case are correspondingly connected in terms of drive, the lifting disks 5, 6 assigned to the tamper rods 2, 3 serving to raise the tamper rods in each case by friction and to drop them again after passing through the lifting disk cams.
  • the lifting disks 5, 6 are mounted on short lifting disk shafts 7, 9, on which the lifting shaft pinions 8 are also arranged. These lifting shaft pinions 8 are connected to the distributor wheel 10, the intermediate wheels 11, 12 and the drive pinion 13. The drive pinion 13 seated on the intermediate shaft 14 is acted upon by the motor 16 and the gear 15 and the toothed clutch 17 arranged between them.
  • the lifting disks 5, 6 each stress the web 19 or the friction lining 20 of the individual tamper rods 2, 3 with their lifting disk cams.
  • the camshaft shafts are mounted individually, their bearing points 22 being designed as toothed rockers 23, 24 which engage with one another and have tooth segments 26.
  • These toothed rockers 23, 24 are connected to one another in the region of the tooth segments via a lever shaft 25 in such a way that, as can be seen from FIGS. 1, 2 and 3, the toothed rockers 23, 24 are pivoted via the lever 28 when the working cylinder 29 is actuated that the lifting disks 5, 6 either approach the web 19 or are lifted off from it.
  • the lever shafts 25 are held on both sides of the tamper rod 2, 3 via a common axle bracket 27. Only one of the two lever shafts has a lever 28. This is sufficient because the movement of the lever 28 is transmitted via the toothed segments 26 to the opposite lever shaft 25 '. Accordingly, the toothed rockers 23 and 23 'and 24 and 24' perform the same movements. The tooth play in the toothed rockers 23, 23 'and 24, 24' is removed by means of spiral springs. This avoids knocking out of the teeth during the periodic engagement of the cam plate cams 41.
  • the tamper foot is designated, which has dimensions corresponding to the ramming shape.
  • the working cylinder 29 moves the lever shaft 25 via the lever 28.
  • the toothed rockers 23, 24 are then moved synchronously, as mentioned.
  • the lifting discs 5, 6 are brought into the operating position via the lifting disc shaft 9.
  • the lifting disks 5, 6 are provided via the hydraulic system.
  • the drive of the lifting shaft pinion 8 is shown in FIG. 4, the individual transmission wheels being designated by 10, 11, 12, 13.
  • FIG. 5 shows the hydraulic circuit diagram, the working cylinder 29 having a special control system, via which the position of the piston rod 32 and the piston 33 or their fixing takes place.
  • a pressure accumulator 35 is connected, which acts as a compensator and absorbs the shocks in the hydraulic system that inevitably arise when the cam disc 41 is placed on the tamper rod 2, 3.
  • rigidly mounted lifting disks 5, 6 can be used, the execution and storage of which is much simpler and cheaper to carry out than previously. This also means that heavier tamping rods can be used if necessary and thus larger amounts of energy can be introduced into the coal cake with the same pounding time.
  • the working cylinder 29 is designed and switched in such a way that displacement is not possible even when the desired standstill is caused by an external force such as, for example, the lifting plate rolling force.
  • the working cylinder 29, which is under load, does not creep even when it is standing for a long time, since the oil spring on the piston side and on the rod side is blocked without leakage oil by the check valve / hydraulically unlockable check valve 36, 37.
  • a double pressure switch 38 which can be set to a minimum and a maximum preload pressure of the lifting disks 5, 6, is energized via the timing relay 39. This is the case if, for a predetermined time, e.g. 2 min the set minimum value was not reached.
  • the maximum value of the lifting disc preload is reached when the working cylinder 29 extends so far that the pressure set as the maximum is present in the double pressure switch 38.
  • This provision of the lifting disks 5, 6 takes place when the position contact 40 indicates a position of opposing lifting disk cams 41.
  • this adjustment is only necessary every one to two months.
  • the pressure accumulator 46 which is connected into the supply line 43 with the accumulator 44 and is arranged behind the check valve 45, serves as pressure buffering.
