Definitions

  • the invention relates to a device for reducing or canceling the bending moment in one or more masts of a movable hoist, in particular a shelf conveyor, the chassis of which runs on stationary roadways.
  • Masts from, for example, shelf-mounted conveyors are subjected to bending as a result of the eccentrically acting load force.
  • a dynamic bending moment component which results from vehicle accelerations, is added to this static bending moment component.
  • step at the mast connection, d. H. in the area of the transition to the chassis relatively high bending moments.
  • the invention is therefore based on the object of providing a device of the type mentioned at the beginning which keeps the deformation caused by constant or changing load low and in a simple and inexpensive manner and reduces or eliminates the proportion of bending moment resulting from vehicle accelerations.
  • This object is achieved in that at least two oppositely S-shaped flexurally elastic tension members such as ropes, chains or the like are available, each over two deflection rollers attached to the hoist at the top and bottom are guided with axes oriented transversely to the direction of travel and are each attached to opposite sides of the mast or masts, fixed, rigid structures provided at the ends of the hoist travel path, and that between the ends of the tension members and the rigid structures are connected to clamping devices.
  • the proposed device moves the mast arrangement parallel to itself when moving the hoist and prevents movement from the vertical position.
  • the solution is also simple and cheap. If the tension members are pre-tensioned accordingly, it also makes it possible to use hoists in which the mast is articulated to the drive beam or which can be moved on a wheel.
  • the invention is shown schematically using the exemplary embodiment of a rack conveyor, the figure showing a side view of the rack conveyor and the parallel guide means.
  • the rigid, non-telescopic mast of a shelf conveyor the lower end of which is rigidly connected to a chassis beam 2.
  • Wheels 3 are arranged on the chassis support 2 in the known manner, by means of which the rack conveyor is supported on rails 4 at the bottom of the bearing.
  • a load carrier 5 is raised and lowered in a known manner, the base plate 6 carries a telescopic table or the like.
  • the upper end of the mast can be guided on an upper guide rail 14 by means of horizontal rollers.
  • two deflection rollers 7a, 8a of the same height are rotatably mounted, the horizontal axes of which are directed transversely to the upper guide rail 14 and thus also transversely to the running rails 4.
  • two rotatable deflection rollers 7b, 8b of the same height or substantially the same height are attached to the lower end of the rack conveyor, the axes of which lie transversely to the running rails 4.
  • the mast 1 is guided in parallel by two ropes 9, 10, one end of which is attached at 11 to a corresponding part of the bearing structure at the end of the rack conveyor travel path.
  • the ropes 9, 10 first run parallel to the upper guide rail up to the upper guide rollers 7a, 8a from the attachment points 11, then, since they are deflected by the guide rollers 7a, 8a, essentially downwards to the lower ones Deflection rollers 7b, 8b are guided, around which they are deflected by essentially 90 ° with the opposite deflection direction as in the deflection rollers 7a, 8a. Finally, the ropes 9, 10 run parallel to the running rails 4 to the left and right up to the rack conveyor chassis ends, where they are each attached to a horizontal tensioning device, such as spring 12 or the like, the other end of which is attached to 13 is fixed to a fixed element attached to the bearing base.
  • the preload of the springs can be chosen so high that slack rope is avoided with the greatest operational rope force.
  • the mast 1 can be connected in an articulated manner to the driving beam 2, which is not shown further.
