Definitions
- the invention relates to a tamping machine for Herstel ⁇ development of a for coking provided, compacted coal cake, associated with the individual Stampfer rods Stampfer rod locks that hold the Stampfer rods for 'the tamping operation and during the setting process in the upper end position by a clamping member.
- 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 discs.
- the transferable contact pressure is therefore limited, so that the higher weight of the tamper rods cannot be securely held by the contact pressure of the segment discs in the case of higher 6 furnaces and therefore longer tamper rods.
- the invention has for its object to provide a tamper bar lock, which also for those with higher Heaters provided heavier tamping rods allows safe operation.
- the clamping part is formed as a shaft eccentrically surrounding sleeve, on which I slide a slide and with an associated clamping wedge on the one hand and the latter is arranged correspondingly with the web of the tamper rod on the other hand, the clamping wedge against unwanted jamming is secured.
- the inventive design of the tamper rod lock it is possible to apply high contact forces to the web of the tamper rod using small pieces and a clamping wedge even with small rotary movements of the shaft.
- the force is transmitted by surface pressure, so that the tamper bar locks with much less wear and tear are still much heavier in their upper end position when the coal cake is placed in the coke oven.
- the slider is rotatably mounted on the sleeve and therefore, as already mentioned above, can be displaced 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 the tamper rod is relieved accordingly released for free fall.
- the slider is arranged to form an upwardly open angle with the web of the tamper rod.
- the clamping wedge thus falls automatically in the various movements to be carried out by it again and again into the wedge seat, so that an always uniform and high transmission of forces to the web of the tamper rod is guaranteed.
- the tamper rod can be lifted out without being loosened, i.e. without using a separate control of the lifting device.
- the lifting device as a whole is thus designed to be structurally much simpler.
- the effect of the tamper rod locks is expediently increased by the fact that the inclined surfaces of the mutually associated sides of the slide and the clamping wedge are designed to ensure self-locking. If the wedge angle or the slope surfaces are chosen 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 sleeve connected to the shaft in a rotationally fixed manner. It is basically known opposed to arrange the segment discs each other ', but this is done as an absolute necessity and without the system to significantly improve. In the present case, however, the implementation of the solution, according to which each tappet rod is assigned two clamping wedges and sliding pieces opposite each other with the shaft connected in a rotationally fixed manner, is a clear improvement, but the system would also work if the Wedges and sliders would only be provided on one of the sides and a contact surface on the opposite side.
- a further expedient embodiment provides that the plate of the clamping wedge that can be placed on the web of the tamper rod is designed to be extendable for the longitudinal axis of the web * . This means that the force-transmitting surface can be enlarged or reduced, if necessary, as required. To increase the clamping forces, it can also be expedient to provide the plate with a friction layer in addition to the existing friction lining on the web. On. ' 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 slider and thus locking of the clamping wedge is ensured, even if dirt has settled after prolonged operation or the surfaces formed by the friction lining have unevenness.
- 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 rod lock achieves its high level of safety in particular in that the force transmission between the lock and the web of the tamper rod takes place by surface pressure.
- the dimensions for the surface pressure. Available standing areas can be selected according to the respective operating conditions or can also be designed to be adaptable.
- 1 is a side view of the tamper rod influenced by two tamper bar locks
- Fig. 2 shows a partial section approximately in the middle of the two shafts of the tamper rod locks.
- the tamper bar lock 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 bars lock 1 across the web * 3 of the tamper bar 2 depending on the circumstances, 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 is covered at the ends by the cover halves 9, 10 so that lateral displacement of the sleeve cannot occur.
- the cover surfaces 9, 10 are connected to the shaft 7 by means of a holding screw. 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. Influence
- the slope surfaces 17, 18 of the clamping wedges 15, 16 and the sliders 13, 14 are matched to one another so that the entire device works self-locking.
- the sides 19, 2o of the mutually associated sliding pieces 13, 14 and clamping wedges 15, 16 are designed as surface areas 17 and 18, respectively. The same is shown in FIGS. 1 and 2.
- Guides 26 are formed on the longitudinal 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, the guide 26 being expediently realized by a groove 27 formed in the slide 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 ramming system is facilitated.
- the area with which the clamping wedges 15, 16 act on the web 3 of the tamper rod 2 is predetermined by the plates ' 3o, 31.
- These plates 3o, 31 are connected to the remaining parts of the clamping wedge 15, 16, as shown in FIG. 2 by the weld seams.

Abstract
Pour réaliser des galettes de charbon comprimées avant la cokéfaction on utilise des machines dotées de systèmes de blocage (1) qui maintiennent les pilons (2) dans leur position finale supérieure. Ces systèmes de blocage (1) sont disposés des deux côtés de la protubérance (3) des pilons (2) et chacun comporte un manchon (8) qui entoure d'une manière excentrique le cylindre (7), sur lequel est disposée de façon à pouvoir glisser une pièce coulissante (13) correspondant à une cale de serrage (15, 16) spéficique. Le côté opposé de la cale de serrage (15, 16) épouse la forme de la protubérance (3) des pilons (2), de sorte que lorsque le cylindre (7) effectue un movuement rotatif approprié, la pièce coulissante (13) est déplacée, appuyant ainsi la cale de serrage (15, 16) contre la protubérance (3) du pilon (2) ou la libérant de cette dernière.To make charcoal cakes compressed before coking, machines are used equipped with locking systems (1) which hold the pestles (2) in their upper final position. These locking systems (1) are arranged on both sides of the protuberance (3) of the pestles (2) and each has a sleeve (8) which eccentrically surrounds the cylinder (7), on which is arranged so to be able to slide a sliding part (13) corresponding to a specific clamping wedge (15, 16). The opposite side of the clamping wedge (15, 16) follows the shape of the protuberance (3) of the pestles (2), so that when the cylinder (7) performs a suitable rotary movement, the sliding part (13) is moved, thus pressing the clamping wedge (15, 16) against the protuberance (3) of the pestle (2) or releasing it from the latter.
