Definitions

  • the invention relates to a ramming machine for the production of a coke, provided for the coking, compressed, with the individual tamper bars assigned tamper bar locks which hold the tamper bars after the tamping process and during the setting process in the upper end position via a clamping part.
  • the tamper rods are then released again in order to be lifted cyclically with the aid of known devices and released for free fall.
  • the contact pressure is transmitted only by the line contact between the tamper rod, which is usually provided with a friction lining, and the segment disks. Therefore, the transferable contact pressure is limited, so that the higher weight of the tamper rods cannot be safely held by the contact pressure of the segment discs with higher 6 m ovens and therefore longer tamper rods.
  • the rammer lock works according to WO-A-82/02055 with a clamping body designed as a wedge.
  • the wedge is pressed via a pneumatic or hydraulic working cylinder into a funnel-shaped opening formed by the tamper rod and an abutment defined on the frame structure of the ramming machine.
  • the cylinder To release the tamper rod, the cylinder must pull the wedge out of the opening. It is difficult to precisely adjust the clamping force, it is difficult to readjust and to install a working cylinder per tamper rod for operation as an additional unit.
  • the invention has for its object to provide a tamper bar lock that enables safe operation even with the heavier tamper bars provided for higher furnaces.
  • the clamping part is designed as an eccentrically surrounding sleeve on which a slide is slidably and with an associated clamping wedge on the one hand and the latter is arranged corresponding to the web of the tamper rod on the other hand, the clamping wedge being secured against unwanted jamming .
  • the design of the tamper rod lock according to the invention it is possible to apply high contact forces to the web of the tamper rod, even with small rotary movements of the shaft, via a sliding piece and a clamping wedge.
  • the force transmission is carried out by surface pressure, so that the tamper rod locks with less wear still fix heavier tamper rods securely in their upper end position when the coal cake is placed in the coke oven.
  • the slider is non-rotatably mounted on the sleeve and therefore, as already mentioned above, can be moved by very small rotations of the shaft, since on the one hand the clamping wedge engaging in the wedge seat is fixed on the web of the tamper rod or, by appropriate relief, the tamper rod for free fall is released again.
  • the slider is arranged with the web of the tamper rod in an upwardly open angle.
  • the clamping wedge thus automatically falls back into the wedge seat during the various movements to be carried out by it, so that an always uniform and high transmission of forces to the web of the tamper rod is ensured.
  • the tamper rod can be lifted out without separate loosening, that is, without the use of a separate control of the lifting device.
  • the lifting device as a whole is thus structurally much simpler.
  • the effect of the tamper bar locks is expediently increased by the fact that the inclined surfaces of the mutually associated sides of the slider and clamping wedge are designed to ensure self-locking. If the wedge angle or the slope surfaces are selected appropriately, the advantageous self-locking of the system is ensured.
  • each tamper rod is assigned two clamping wedges and sliding pieces opposite each other with the shaft connected in a rotationally fixed manner.
  • segment disks it is known in principle to arrange the segment disks opposite one another, this is an absolute necessity and without significantly improving the system.
  • the implementation of the solution, according to which each tamping rod is assigned two clamping wedges and sliding pieces with the shaft connected in a rotationally fixed manner a clear improvement occurs, but the system would also work if the clamping wedges and sliding pieces only one of the sides and on a contact surface would simply be provided on the opposite side.
  • a further expedient design provides that the plate of the clamping wedge which can be raised on the web of the tamper rod is designed to be extendable in the longitudinal axis of the web. This means that the force-transmitting area can be increased or reduced if necessary.
  • the plate can also be useful to provide the plate with a friction layer in addition to the existing friction lining on the web. In this simple way, the holding force can be effectively increased.
  • a uniform actuation of the tamper rod lock is ensured according to an embodiment of the invention in that guides are assigned to the slide on the longitudinal sides. This effectively prevents the individual parts of the tamper rod lock from sliding sideways.
  • a groove is expediently formed in the longitudinal sides in which the guide strips assigned to the clamping wedge are held. A uniform displacement of the sliding piece and thus locking of the clamping wedge is thus ensured, even if dirt has settled after prolonged operation or the surfaces formed by the friction lining have irregularities.
  • securing the clamping wedge in the open position of the stem rod lock is expediently achieved in that the groove is assigned a key securing the clamping wedge in the open position.
  • the clamping wedge is effectively protected against unintentional jamming in the open position, since it is prevented easily and securely from sliding in too far by the feather key.
  • the invention is characterized in particular by the fact that a secure system of a tamper rod lock is created which engages securely regardless of the weight of the individual tamper rod and which remains fully effective even after longer operating times and any wear that may have occurred.
  • the advantageous tamper bar lock achieves its high level of security in particular in that the force transmission between the lock and the web of the tamper bar takes place by surface pressure.
  • the dimensions of the areas available for the surface pressure can be selected according to the respective operating conditions or can also be designed to be adaptable.
  • the tamper bar lock 1 shown in FIGS. 1 and 2 is intended to fix and hold the tamper bar 2 in its upper end position while the coal cake is placed out of the mold into the coke oven.
  • the tamper bar locks 1 act flat on the web 3 of the tamper bar 2, depending on the circumstances, a part of the web height or the entire web between the two flanges 4, 5 of the tamper bar locks 1 and 6 is influenced.
  • the individual tamper rod locks 1, 6 each have a driven shaft 7, on which an eccentric sleeve 8 is clamped in a rotationally fixed manner.
  • the sleeve 8 is formed in one piece and covered at the ends by the cover halves 9, 10, so that the sleeve cannot be moved laterally.
  • the cover surfaces 9, 10 are connected to the shaft 7 by means of retaining screws. With 11 a lubrication connection or a grease nipple is designated.
  • the sliders 13, 14 are rotatably connected. These sliders are wedge-shaped and can be moved laterally over the sleeve 8 with a corresponding rotation of the shaft 7. They influence the clamping wedge 15, 16 seated in the wedge seat created between the sliders 13, 14 and the web 3.
  • the slope surfaces 17, 18 of the clamping wedges 15, 16 and the sliders 13, 14 are matched to one another in such a way that the entire device works in a self-locking manner.
  • the sides 19, 20 of the mutually associated sliders 13, 14 and clamping wedges 15, 16 are designed as a slope surface 17 and 18, respectively. The same is shown in FIGS. 1 and 2.
  • Guides 26 are formed on the long sides 25 of the sliders 13, 14 and clamping wedges 15, 16. In addition, a uniform sliding of the two parts against one another is ensured, wherein the guide 26 is expediently implemented by a groove 27 formed in the slider 13, 14 or a guide strip 28 assigned to the clamping wedge 15, 16. This guide strip 28 is releasably connected to the clamping wedge 15 or 16 via retaining screws 29, so that the assembly of the entire rammer lock system is facilitated.
  • Fig. 1 provides, in addition to the described design of the feather key, alternatively that Clamping wedges are assigned to eyelets 23, on which the rope 22 guided over the deflection roller 21 is held and secured. On on the other hand, it is attached to the eyelet 24 on the housing, so that the clamping wedge 15, 16 is prevented from falling too far beyond the position predetermined by the length of the cable 22.
  • the area with which the clamping wedges 15, 16 act on the web 3 of the tamper rod 2 is predetermined by the plates 30, 31.
  • These plates 30, 31 are connected to the remaining parts of the clamping wedge 15, 16, as is illustrated in FIG. 2 by the weld seams.
