Definitions

  • the invention relates to a friction wheel drive for lower belt trolleys, trolleys and the like. with a chassis which carries at least one set of rollers for the movable mounting of the chassis on a running rail and on which a friction wheel drive unit consisting of a drive motor, a gear and a driven friction wheel is mounted, the friction wheel of which can be brought into engagement with the outer surface of the lower flange of the running rail.
  • the approach dimension of the undercarriages or undercarriage combinations towed by such a friction wheel travel drive via a coupling rod is increased on one side by the length of the tractor including the coupling rod, a pantograph trolley frequently also being provided between the tractor and the undercarriage or undercarriage combination, which also runs on the running rail and by which a further increase in the starting dimension of the undercarriage or undercarriage combinations is required.
  • the friction wheel drive itself cannot accept loads and works as a pure tractor.
  • the approach dimension of the bottom flange trolley is also extended on one side by the - longitudinal dimensions of the carrier of the friction wheel drive unit and its wheel set assigned at the end; it will only be the length of the coupling rod otherwise present between the none Tra g load aufmonyden.Reibradfahrantrieb and the load-bearing Unterflanschlaufkatze saved. Since the carrier of the friction wheel drive unit of the friction drive is supported directly on a wheel set bearing block of the load-bearing bottom flange trolley, this friction drive is not universally applicable, but only usable for bottom flange trolleys or trolleys that have a special horizontal coupling axis for the carrier of the wheel set bearing block Have friction wheel drive.
  • the object of the invention is a universally usable friction wheel travel drive, which makes it possible to create lower belt trolleys, trolleys, lower belt drive combinations, which are characterized by an extremely small approach dimension, while at the same time ensuring a simple, reliable construction of the friction wheel travel drive.
  • the friction wheel travel drive mentioned at the outset is characterized according to the invention in that it is designed as a load-bearing friction wheel running gear which has devices for coupling a load or a load-bearing means.
  • the payload can be, for example, a hoist (electric hoist or hand hoist), while the payload can be picked up directly on the lifting device.
  • the devices for coupling a load or a load-carrying means can advantageously have a load-carrying bracket which is attached to two suspension points of the friction-wheel drive unit located on both sides of the friction wheel.
  • This load suspension bracket can be partially surrounded around the friction wheel, as is also possible that the load suspension bracket is detachably attached to the chassis.
  • the friction wheel travel drive can also be used as a pure tractor if the friction wheel vehicle has means for coupling at least one load-bearing single or multiple running gear mounted on the running rail.
  • These coupling means can be arranged so as to engage at least one suspension point of the friction wheel drive unit pivotably suspended on the chassis, it then being expedient that the load-bearing bracket mentioned is optionally interchangeable with a coupling rod.
  • the arrangement can be simple be made that on the friction wheel undercarriage at one end at least one load carrier designed for coupling a load or a load-carrying means is mounted, the other end is supported on a single or multiple drive or a drive combination mounted on the running rail.
  • the load carrier can be connected in an articulated manner to the friction wheel undercarriage and / or the undercarriage or undercarriage combination in order to be able to easily negotiate tight curves.
  • the friction wheel undercarriage carries at least one pantograph for the drive motor of the friction wheel, which can also be arranged directly on the undercarriage of the friction wheel undercarriage. This eliminates the need for a separate pantograph wagon, which in turn would increase the starting dimension of the friction wheel undercarriage.

  • the geared motor 15 is designed as a slip-on geared motor; its transmission output shaft 21 is plugged onto a correspondingly designed end of the shaft 18 of the friction wheel 17, wherein a spline connection or a spline connection indicated at 22 in FIG. 5 ensures a rotationally fixed coupling.
  • the gear 16 is otherwise screwed to the housing 20 via torque supports, one of which is shown at 23 in FIG. 5. After loosening this screw connection, it can easily be pulled off to the side.
  • a terminal box 24 for the electrical leads to the geared motor 15 is fastened to the housing 20 such that it remains easily accessible from the outside.
  • the friction wheel drive unit 14 is anchored via a presettable, releasable lock 25, which is designed in the form of a two-part standardized toggle lever tension lock (DIN 3132 to 3134).
  • a bearing block 27 (FIG. 3) is pivotally mounted on the supporting axis 12, to which an essentially U-shaped bearing bracket 28 is fastened by means of screws 29 (FIGS. 3, 4), to which an actuating lever is attached by means of an axis 30 31 of the tension lock 25 is pivotally mounted.

  • Individual spacers 41 can also be replaced by disc springs.
  • a hook 44 is screwed laterally at 45, which cooperates with the locking hook 34 in the manner shown in FIG. 3 in such a way that when the tension lock 25 is closed, the housing 20 via the bracket 35 on the end at 38 in the bearing block 27 guided bolt 37 is positively supported on the washers 41.
  • a spring catch 46 is provided on the locking lever 33, which protrudes into a corresponding opening 47 in the actuating lever 31 and is releasably latched to the edge thereof.
  • the number of washers 41 is selected such that, when the tension lock 25 is closed, the friction wheel 17 is pressed against the underside of the lower flange 5 of the running rail 6 with a predetermined contact pressure.
  • This presetting is already made during the manufacture of the friction wheel travel drive or when replacing a defective friction wheel 17, so that during the final assembly only the tension lock 25 needs to be closed without having to do so on site and place further adjustment or adjustment work would be necessary.
  • the friction wheel 17 can be released from the lower flange 5 of the running rail 6 by simply opening the tension lock 25 and thus made freely accessible, since when the tension lock 25 is released, the entire friction wheel drive unit 14 can be pivoted downward about the right supporting axis 12 in FIG. 1 . Disassembly of the friction wheel drive unit 14 is also possible without great effort; all that is required is to pull out the associated (FIG. 1) right supporting axis 12 laterally.
