    专利说明:

    The present invention relates to a cable pulling device, in particular brochure pulling system for a stage or the like., Wherein a plurality of each having at least one rope having cable drums is coupled to a common drive means via a common drive shaft.
    Such Seilzugeinrichtungen be used for example in conjunction with stages or the like., Where they serve for a movement of brochures, individual pieces, stage components and the like. In particular in the vertical direction. For this purpose, rollers or cable drums are usually arranged above the stage on a so-called lacing floor essentially at fixed positions, via which optionally a plurality of cables run, wherein a plurality of such cable drums are coupled to a common drive device via a common drive shaft, thus also larger dimensions and / or to move objects of greater weight. With regard to such known cable pulling devices, for example, DE-Al 87 14 758, DE-Al 26 49 370, DE-Al 24 00 848 or DE-U 79 14 707 referenced. A disadvantage of these known embodiments of Seilzugeinrichtungen is in particular the fact that essentially the individual cable drums, which determine the point of departure or the position of such a rope to be provided at predetermined positions and provided between individual cable drums drive shaft not only for transmitting a drive movement of a common drive device is used, but is usually also fixed to a corresponding holder or guide and thus also used to support possibly high bearing forces or stresses.
    The present invention aims to eliminate the disadvantages of the known prior art, in particular with regard to a substantially fixed positioning of individual cable drums and to further develop a cable pulling device, in particular in adaptation to different local
    Conditions an adaptation of the positioning of individual cable drums at conveniently simplified storage is possible.
    To solve these objects, a cable pull device of the type mentioned is essentially characterized in that the drive shaft has a profile deviating from a circular profile, which cooperates with a correspondingly complementary profiling of the cable drums and / or the drive means. Characterized in that according to the invention, both the drive shaft and the cable drums and the drive device are each formed with a profile differing from a circular profile, a simple power transmission can be provided by the deviating from a circular profile profile, for example, by a simple plug-in system. In contrast, in embodiments according to the known state of the art with a circular drive shaft, a complex bearing of the drive shaft was required both in the cable drum and in the drive device for a proper transmission of the forces. By providing such a simple and reliable coupling by a profile deviating from a circular profile, an adaptation to optionally different positions or possibly also subsequent adjustments of a cable drum can moreover be carried out simply and reliably in accordance with local conditions, since, for example, when using modular elements the drive shaft on-site adaptation to possibly different requirements is possible. When forming the drive shaft over the entire length with a profile deviating from a circular profile, a desired positioning of a cable drum can be achieved by simply cutting to length a drive shaft or a subregion thereof. For a particularly simple and reliable coupling between a drive shaft and a cable drum and / or drive device and to provide easy to produce profiles is proposed according to a preferred embodiment, that the profile of a regular profile, such as a square, hexagonal or octagonal profile is formed , For a simple and reliable coupling between a cable drum and the profile of the drive shaft deviating from a circular profile, it is proposed according to a further preferred embodiment that the cable drums are formed on at least one end region with a support or flange oriented substantially normal to the drive shaft, in which the complementary to the profile of the drive shaft profiling is provided. This makes it possible in a simple manner to provide a torque transmission via the drive shaft with simple coupling with a cable drum or the drive device, optionally existing cable drums or drive means in a simple manner by providing such a support or flange in adaptation to a drive shaft according to the invention can be adapted or retrofitted from a circular profile profile. For the inventively possible and easily deployable modular design of the cable pulling device according to the invention is also proposed that the drive shaft is formed by a plurality of coupled to the respective cable drums or rod-like elements, as corresponds to a further preferred embodiment of the cable pulling device according to the invention. Such rod-like elements can, as already mentioned above, be provided according to the local conditions with a suitable length or cut to desired lengths directly on site for positioning the drive device and / or cable drums to be coupled thereto. • ·· ·

    As already stated above, in addition to a fixed positioning of individual cable drums and an often complex torque transmission by providing circular profiles for the drive shaft in existing systems often disadvantageous that the drive shafts must be made correspondingly massive, there in addition to a torque transmission for driving the individual To be coupled to cable drums also by the storage of the drive shaft to a bracket or a scaffold also possibly large stresses and loads must be absorbed by the drive shaft or its sub-elements. In order to relieve the drive shaft provided according to the invention, it is proposed according to a further preferred embodiment that the cable drums are in particular displaceably mounted in or on a holder or guide. In this way, the individual elements of the drive shaft or the entire drive shaft can be made correspondingly simpler and lighter or less massive, since the inclusion of the loads or the stresses occurring by an optionally high weight, the moving elements occurring on the on or in a holder or guide mounted cable drums are received, while on the arranged between individual cable drums and the drive means drive shaft only a transmission of torque for the movement of the cable drums is required. For a further adaptation of the positioning of the individual cable drums according to the invention for the entire cable pull device beyond preferably provided that the cable drums are slidably mounted in or on the holder or guide.
    To maintain a constant rope departure or Abwickelpunkts of the rope during a movement of the cable drums is proposed according to a further preferred embodiment that the cable drums are slidably mounted in accordance with a winding or unwinding of the individual ropes in or on the holder or guide. Thus, a fixed or fixed rope departure point can be provided independently of the delivered rope length, wherein a plurality of coupled to a common drive shaft cable drums are moved according to evenly in accordance with their up or Abwickelbewegung on or along the holder or guide. For a simple and reliable coupling of the multi-element drive shaft with the drive device is proposed according to a further preferred embodiment that the drive shaft or a rod-like element thereof or a cable drum is coupled or coupled to the drive means.
    In addition to substantially rectilinear Seilzugeinrichtungen deviating geometric configuration or positioning of individual cable drums are required in accordance with local requirements may require a straight or aligned alignment of the drive shaft and the cable drums to be coupled to it. In this connection, it is proposed according to a further preferred embodiment of the cable pull device according to the invention that at least one articulated connection between two mutually adjacent cable drums in the drive shaft or a rod-like element thereof is provided or integrated. By such a hinge connection can thus, for example, arcuate
    Provide arrangements of a cable attachment or angled embodiments. For such, deviating from a straight-line arrangement of positioning or arrangements is also provided that the drive shaft or rod-like elements thereof is or are formed by a propeller shaft, as corresponds to a further preferred embodiment of the cable pulling device according to the invention.
    According to local conditions, the drive device may be provided at different positions and along the extension of the drive shaft and the cooperating cable drum. In this connection, it is proposed according to a preferred embodiment that the drive device is arranged at one end of the cable pull device or between two adjacent cable drums.
    In addition to an invention preferably proposed movement of individual rope drums either as a function of the Aufoder Abwickelbewegung or the movement of the entire cable pulling device beyond the cable pulling device can be mounted on or in a holder or guide slidably or movably, as corresponds to a further preferred embodiment. Such additional degrees of freedom according to the requirements different positioning of the entire cable pulling device are provided, which can be integrated for example as a climbing train in a truss system by an inventively additionally provided displaceable or movable storage of the cable pulling device, which is for example fixed to a ceiling of a stage , In addition to such a vertical mobility can also be provided in addition by a corresponding arrangement of brackets or guides optionally also a significant horizontal mobility of the entire cable pulling device available.
