Definitions
- the invention relates to a ramming device for the production of a suitable for the coking, compressed coal cake with several, over the length of the ramming arranged arranged tamping rods, on the web of which there are friction linings on both sides, attack in the lifting discs with cam-like segments, each on a common , rotating camshaft shaft are detachably and provided with a grain diameter corresponding to the respective shaft section.
- the tamping rods are generally designed as double T profiles, with a friction lining being applied to both sides of the connecting web.
- This web which is provided with friction linings, symmetrically opposed lifting disks engage, each of which is arranged on a continuous shaft and has a cam-like partial area over which the individual tamper is lifted under the action of the frictional force, the lifting disks acting on the web accordingly on both sides of the web .
- the lifting disks release the tamper rod again in the recessed area of its circumference, so that it falls down and compresses the coking coal with its pounding foot.
- the individual lifting disks are offset by 90 ° on a continuous shaft, so that the individual tamper bars arranged in the longitudinal direction of the tamping mold are lifted in a certain cycle and fall freely downwards.
- Corresponding lifting disks can be found in DE-OS 26 03 677.1.
- the components consist of a hub part a center bar, made of circular bearing buffers, side retaining plates and the protruding lifting cam part.
- the stroke of the tamper rod takes place via the rotary movement of the lifting disks via a hub part which is fastened to the lifting disk shaft with a wedge connection.
- the frictional force is transmitted from the lifting disc shaft to the protruding lifting cams of the lifting disc via round bearing buffers, which are distributed around the circumference of the lifting disc. They are connected on one side to the center bar of the hub part and on the other side to the side retaining plates that support the lifting cam by means of screws.
- the round storage buffers consist of a round rubber part, which has a vulcanized metal plate with screw-in options on the head and foot side.
- the design of these circular storage buffers is designed so that they primarily absorb pressure loads. The possibility of absorbing pressure to shear loads is in the ratio 3: 1. For this reason, this type of circular bearing buffers can be found almost exclusively as vibration-damping elements in machine bearings.
- the tamper rods are lifted by frictional engagement of the lifting disks. This frictional connection is achieved by turning the hub part to the protruding lifting cam part.
- a disadvantage of this known design is that the individual circular bearing buffers are subjected to torsion, which does not correspond to their design. The lifting discs therefore only have a very short service life.
- the invention is therefore based on the object of providing a ramming device with long service life and uniformly designed lifting disks.
- the object is achieved according to the invention in that the lifting disks consist of a lifting segment ring having the cam-like partial area and a hub ring arranged at a distance from it, which are firmly connected to one another via an elastic ring and that the hub ring has a rotationally fixed connection to the driving shaft.
- the lifting segment ring and scar ring representing the lifting disks are connected over the entire area via an elastic ring, so that there is always a uniform frictional engagement between the lifting disks and the tamper rod to be lifted.
- there is no need to maintain different types of lifting discs because they are all of the same design, namely with a hub ring which preferably has a tapered seat on the shaft side. This gives the possibility of a continuous shaft made of drawn bearing material, i. H. to use a camshaft shaft without shaft shoulders.
- the lifting discs of the same design are locked on it at the intended distance by means of corresponding fixing parts in any position. Long service life and significantly lower manufacturing costs with advantageously low reserve of the individual lifting disks can be achieved with the solution according to the invention, so that both the operating costs and the investment costs can be reduced.
- the elastic ring is connected to the hub ring and the lifting segment ring (resulting in a lifting disk), it being provided according to an expedient design that the hub ring and the lifting segment ring consist of metal and that the elastic ring is vulcanized onto them.
- a vulcanization ensures that the hub ring, hub segment ring and elastic ring are effectively connected to one another over the entire contact surface, and the frictional forces can thus be transmitted effectively to the ramming via the lifting disks.
- glue the hub ring, elastic ring and lifting segment ring together. Because of the adhesives available today, this also ensures a correspondingly effective connection of the individual parts to one another.
- the conical seat has an inclination of 1:12, so that the respective lifting disk or the hub ring can be effectively fixed to the lifting disk shaft with the aid of suitable means.
- the closed lifting segment ring is expediently provided with a lifting cam which is designed with an inlet and an outlet. This ensures smooth running.
- the lifting disk consists of two or more sub-segments which are releasably connected to one another by means of a butt joint to ensure that they rest evenly on the web of the tamper rod.
- a screw connection can be provided which extends into the elastic ring in order to improve the connection to this component at the same time. It may also be expedient to form the elastic ring in two parts and possibly also the hub ring, so that there is no need to be pushed onto the shaft and instead enable on-site assembly.
- the term elastic ring clarifies that it consists of an elastic material, and it has been found to be particularly expedient to manufacture the elastic ring from a rubber compound, it being advantageous in turn that such a rubber compound can advantageously be vulcanized onto the hub ring and the lifting segment ring .
- the ring can also have a type of web, in that it first decreases from the hub ring in the direction of the lifting segment ring and then increases again.
- the hub ring and / or the lifting segment ring have a roughened surface or projections and recesses that optimize the connection.
- the arrangement of knobs and holes can also be advantageous if it is ensured that the knobs in the holes cannot shear off. If one thinks of the lifting cement ring, the arrangement of bores and knobs can even be advantageous, because then the rubber compound may cause the friction effect on the web the tamper bar still increased.
- a fixing of the respective lifting disc on the shaft or the lifting disc shaft is optimized and simplified according to an embodiment of the invention in that the hub ring is assigned an axially displaceable clamping and withdrawal sleeve.
- This clamping and withdrawal sleeve lies tightly against the shaft, and expediently at the point where the lifting disk is to be fixed, so that the lifting disk is pulled onto the clamping sleeve.
- the arrangement of the cam plates can thus be achieved safely at any point on the cam plate shaft by pushing the cam plate onto the clamping sleeve. When pushed on, the cam-like section is simultaneously brought into the position that is provided for the respective lifting disk.
- the invention provides that the shaft lock nut is connected to the head end of the hub ring. It has exactly the position that is important for the definition of the individual components.
- the assembly of the clamping and withdrawal sleeve is further facilitated in that it consists of two partial sleeves which are designed to overlap one another in the edge area. It can therefore be placed on the already assembled shaft without having to detach the shaft from any bearings or drives. Since the partial sleeves overlap each other in the edge area, and preferably alternately, fixing to the shaft is generally not necessary at all. Rather, as described above, the clamping and withdrawal sleeve is then simultaneously fixed to the shaft via the shaft nut with the hub ring. The hub ring pushed over the partial sleeves also ensures that the two partial sleeves cannot come loose, but rather remain securely in the predetermined position during operation.
- clamping and withdrawal sleeve has one or more oil distributor grooves and oil supply bores.
- the invention is characterized in particular by the fact that a ramming device is created in which the assembly of the individual lifting disks is considerably simplified by their simple and uniform structure, which is noticeably noticeable in the manufacturing costs. All lifting disks have the same hub and hub segment ring as well as the elastic ring connecting the two. The rosion forces that occur between the lifting segment ring and the hub ring during operation of the lifting disc are optimally transmitted via the resilient elastic ring, which significantly increases the service life. It is also advantageous that, as already mentioned, the individual lifting disks are identical in terms of their structure, the hub ring having a conical seat and being combined or combinable with an adapter and withdrawal sleeve in such a way that the individual lifting disks practically at any point on the can be assembled throughout the same shaft. This assembly is much easier because the staggered shaft shoulders of the cam plate shaft can be dispensed with. This constructive training significantly reduces investment costs and operating costs, especially thanks to cheaper storage.

- FIG. 2 shows a section through one of the lifting disks
- Fig. 4 split disc in side view
- FIG. 6 a section through one of the lifting discs according to FIG. 5.
- the individual tamping rods 7 designed as double-T profiles are lifted over lifting disks 15, 16, 17 located on both sides of the ramming bar 10, as can be seen in FIG. 1 and FIG.
- the two identical, symmetrically opposed lifting disks 15, 16, 17 lift the tamper rod 7, which is provided with a friction lining 11 on both sides, by synchronously rotating in opposite directions with simultaneous pressing with its cam-like partial area of its lifting segment ring 1, 1 the length of the lifting cams la, la 'and determined by the lifting disc diameter.
- the tamper rod 7 is raised as long as the lifting cam on the friction lining 11 8 provided web 10 attacks.
- the lifting disks 15, 16, 17 consist of the outer lifting segment ring 1, 1 ', the hub ring 2, 2a, 2b and the elastic ring 3, 3a lying between the two, and the non-rotatable connections to the driving lifting disk shaft 6.
- the elastic ring 3, 3a consists for example made of rubber, which is vulcanized onto the metal lifting segment ring 1 and 1 'and hub ring 2, 2a, 2b. It can be seen from FIG. 2 and FIG. 6 that the elastic ring 3, 3a, starting from the lifting segment ring 1, 1 ', initially becomes narrower in order to then increase in thickness again towards the hub ring 2, 2a, 2b.
- the elastic ring 3, 3a transmits the frictional force from the driving lifting disk shaft 6 to the tamper rod 7 to be lifted. Furthermore, it also takes on cushioning tasks during the lifting process.
- the hub ring 2, 2a has a conical seat 19, which is designed to correspond to the clamping and withdrawal sleeve 4, which, according to FIG. 2, is pushed onto the camshaft shaft 6, lies tightly against the latter and has the reverse conical shape on the outside.
- the hub ring 2, 2a advantageously has a taper seat 19 with 1:12.
- the clamping and withdrawal sleeve 4 is pulled up with the shaft nut 5 via the conical seat 19 onto the hub ring 2, 2a, the shaft nut 5 being arranged on one side of the hub ring 2, 2a. Due to this design, such a lifting disk 15 or 16 can be fixed practically at any point in the longitudinal axis of the lifting disk shaft 6 in order to take over the lifting function of the tamper rod 7.
- the clamping and withdrawal sleeve 4 has one or more oil distributor grooves 8 which can be reached via oil supply bores 9. They are used for mounting and dismounting of pressure oil.
- the lifting disks 15, 16, 17 shown in FIGS. 1, 2, 4, 5 and 6 can be formed in two or more parts. This is shown in FIG. 4, reference numerals 21 and 22 being used for the partial rings of a two-part lifting lift 15, 16, 17. In the case of a multi-part lifting disk 15, 16, 17, the lifting segment ring 1 'and the hub ring 2a are connected to one another via the elastic ring 3a. The partial rings 21, 22 are detachably connected via the joint 18.
- the facing surfaces 26 or 27 are roughened or provided with projections or recesses.
- FIG. 5 and FIG. 6 show a possibility of equipping the ramming machines in operation, which still have stepped lifting disk shafts 6, with lifting disks 17. They also consist of a hub ring 2b and a lifting segment ring 1 with a connecting elastic ring 3. In order to take account of the different shaft heels, this embodiment also has a grooved ring 12 with corresponding shaft bores. This groove ring 12 advantageously has four grooves 32, 33 offset by 90 ° on the outer circumference. The receiving hub ring 2b, however, only one on the inner circumference. 10
