Definitions
- the invention relates to a link chain as a conveyor chain, in particular for a bucket elevator or the like, consisting of at least two strands of individual link plates arranged parallel to one another, the individual link plates being connected to one another by means of chain bolts arranged transversely to the link plane such that each chain strand consists of alternately arranged inner link plates and outer link plates there is and each chain pin carries an inner link and an outer link of both chain strands, with a bushing carrying the respective inner link of both chain strands being arranged on the chain pin to support the inner link, and at least one additional link between two adjacent chain pins on the outside of the associated outer link of a chain strand is arranged, which is supported at one end on one chain pin and abuts the adjacent chain pin at its other end.
- the invention is therefore based on the object of establishing a simply constructed and efficient possibility of determining a chain elongation which exceeds the permissible dimension for a link chain of the type mentioned at the outset.
- the basic idea of the invention is that the additional plate is designed as a test plate to visualize a chain elongation that has occurred, by its other end resting against the adjacent chain pin under a positive connection and with a certain increase in the spacing of the chain bolts from one another due to the chain lengthening pivoted from the longitudinal axis of the chain strand while canceling this form-fitting connection around the other chain pin.
- the invention is associated with the advantage that the additional arrangement of a test bottle does not require any particularly considerable outlay, in particular no outlay in terms of measurement technology for the detection of chain elongation with a possibly complicated structure.
- DE-OS 28 11 240 describes an additional link designed as a chain lock for securing a carrier carrying a driver and to be inserted into the link chain, which is attached at one end to a chain pin and with its free end encloses the associated adjacent chain pin in a form-fitting manner ; a release of this end of the additional link, which is not inseparably connected to the chain bolts, is not provided and contradicts the safety function assigned to the additional link.
- the additional tab already provided in DE-AS 10 04 545 is intended to secure the hinge pins that support them against rotation and the rollers that are seated on the hinge pins against axial displacement;
- the additional link known from DE 34 19 981 AI is intended to allow a displacement of the chain pins connected to it and a functional link carried by the chain link transverse to the longitudinal axis of the chain strand, while the additional link disclosed in DE-OS 18 03 068 for Reinforcement of the holder of conveyor cups is provided.
- DE 33 47 340 AI shows on the lateral ends of the axially projecting axially projecting chain pins reinforced locking tabs that allow opening of the chain strand and thus a simple change in chain length.
- all previously known additional plates have no relation to the determination of a chain elongation that has occurred.
- the test bottle has at its end opposite the bearing a partially surrounding the associated chain pin, one-sided open recess, the extent of the mutual axial overlap of the recess and chain pin corresponds to the permissible chain elongation, so that when the permissible chain elongation, the connection of the recess with the chain pin is removed and the test bottle is moved away from the longitudinal axis of the associated chain strand.
- test bottles are arranged distributed over the chain strand of a link chain.
- a test station associated with the link chain can be provided according to one exemplary embodiment of the invention, for example in the form of a light barrier or a mechanical button.
- a test station associated with the link chain can be provided according to one exemplary embodiment of the invention, for example in the form of a light barrier or a mechanical button.
- an embodiment of the invention is shown, which is described below. Show it:
- Fig. 2 shows the test bottle arranged between two adjacent chain bolts in a side view.
- the link chain shown in FIG. 1 consists of two parallel chain strands 10, each chain strand being formed by alternately arranged inner link plates 12 and outer link plates 11.
- the chain bolts 13 provided for connecting the respective inner and outer plates of both chain strands 10 each have an inner plate 12 and an outer plate 11 of both chain strands 10, a bushing 14 carrying the respective inner plate 12 of both chain strands 10 being arranged on the chain pin 13 for mounting the inner plates 12 is.
- the outer plates 11 and the inner plates 12 of at least one chain strand 10 are provided with holding plates 15 for connecting cups, for example, when using a plate chain in the context of a bucket elevator.
- test flap 16 is placed on the outside of a chain strand 10 onto the chain pins 13, which have a greater axial extent, the design of which can be seen in detail in FIG. 2.
- the test bottle 16 is supported with a bearing bore 17 on the one chain pin 13, and the test bottle 16 has at its other end a recess 18 which is open on one side and with which the test bottle 16 partially engages around the associated chain pin 13 to produce a positive connection .
- the overlap defined by the gripping in the axial direction of the test bottle and designated by the reference numeral 19 corresponds to the permissible chain elongation, which means that if the link chain is elongated beyond the extent of the overlap 19, this positive connection is canceled and the test bottle 16 - at least in the case of a horizontally extending link chain - assumes the position shown in broken lines in FIG. 2, in which the test bottle deviates from the direction of the chain strand 10, so that this different position of the test bottle can be detected by means of a suitable test station, for example in the form of a light barrier or a feeler device. If the test station detects such a deviating position, it can be easily recognized that the chain elongation has exceeded the permissible level.
