DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention concerns a coke compactor for the production of a compressed cake of coal intended for coking, with rod retainers associated with the individual compacting rods, which retain the several rods after the compacting procedures and during the charging procedure at the upper limit of travel by means of a clamping element.
BACKGROUND OF THE INVENTION
To achieve a sufficient quality of coke, the coking coals are compacted by means of free-falling compacting rods in a form provided therefor, and then placed into the coke ovens in the shape of a compacted cake of coal. During the charging of the coke oven the compacting rods must be retained in their upper limits of travel so that the compacted cake of coal can be removed from the form. Until now, the retention of the raised stamping rods was accomplished by eccentrically journaled segment disks which are arrayed rotatably about a horizontal axle and lie against the compacting rods due to their own weight. By appropriate counterrotation of the shafts carrying the segment disks, the compacting rods are then released again, in order to be raised rhytmically and released for free fall by means of known devices. In the known compacting rod retainers, the transfer of the pressure force is effected by the line contact between the compacting rod which is usually equipped with a friction lining and the segment disks. The transferrable pressure force is thus limited, so that for ovens higher than 6 m, and the longer compacting rods necessitated thereby, the likewise higher weight of the compacting rods cannot be retained securely by the pressure force of the segment disks.
OBJECT OF THE INVENTION
It is an object of the invention to provide a compacting rod retainer which makes a reliable operation possible with the heavier compacting rods provided for taller ovens.
SUMMARY OF THE INVENTION
In the present invention, the object is achieved in that the clamping element is formed as a bushing surrounding the shaft eccentrically, to which a carrier is slidably engaged with an associated clamping wedge provided thereon and cooperating with a web of the compacting rod, the clamping wedge being secured against unwanted clamping.
By means of the implementation of the compacting rod retainer according to the invention, it is possible to exert high pressure forces upon the web of the compacting rod via the carrier and clamping wedge even with small rotational motions of the shaft. Thereby it is to be emphasized, and is advantageous, that the transfer of forces is effected by area pressure, so that the compacting rod retainers, with less wear, will fix significantly heavier compacting rods in their upper end position when the coal cake is placed into the coke oven. The carrier engages the bushing and is fixed against rotation, and as already mentined above, can be shifted by means of very small rotations of the shaft so that the clamping element engaging the web of the compacting rod can be immobilized, or retracted whereby the compacting rod can again be released for free fall.
In order to assure an effective wedge seat, it is provided according to the invention that the carrier is arranged so as to form an upwardly open angle with the web of the compacting rod. Thus the clamping wedge during the several motions to be effected by it always drops automatically into the wedge seat, so that an always constant and high transfer of forces upon the web of the compacting rod is assured. The removal of the compacting rod can be effected without separate loosening, that is without a separate control of the lifting device. Thus the entire lifting device construction is much simpler. Suitably, the effectiveness of the compacting rod retainers is further increased in that the inclined surfaces at the cooperating sides of the carrier and clamping wedge are formed so as to secure a self-locking action. By suitable correct selection of the wedge angle or the inclined surfaces, the advantageous self-locking of the system is assured.
