Definitions

  • Such a means of conveyance may be, for example, a lift or a lifting platform for loads or persons, for which usually very expensive drive system or devices are provided, which usually take up a relatively large amount of installation space.

At least two double-acting cylinders are provided for each support leg of the lifting platform, which are supported on structures of the support leg itself and thus allow only a gradual increase or decrease.

The same applies to the lifting device disclosed in GB 612 201 for a support leg of a buoyant lifting platform.
  • the system described here comprises a common arrangement of lifting jack and support leg, wherein for each support leg at least two double-acting cylinders are attached to the jacking platform, which are supported in unison on structures of the support leg itself and so an exclusively gradual increase or decrease by changing the height of the overall arrangement effect from jack and support leg.
  • the means of transport described above is characterized in that at least two oppositely moving linear drives are provided for the or each transport element, which alternately support each other at support points and thereby during their respective stroke a drive torque to the transport element in the sense of a substantially continuous Exercise movement of the transport element, wherein at any time at least one linear drive of a support point is supported.
  • Linear drives can be designed to be very narrow, so that, when arranged essentially parallel to the direction of movement of the transport elements, hardly any additional installation space is required. is needed, and moreover can be ensured with such a construction, a substantially continuous movement of the transport element, without disturbing in particular passenger transport stop phases.
  • a similar effect of achieving a steady and uniform movement of the means of transport despite transfer of the drive effect between two different linear drives can also be achieved by an alternative embodiment in which at least two counter-rotating linear actuators emanating from a common base element, which base element parallel over at least a third linear drive can be moved to the working stroke of opposing linear actuators.
  • the transport element is provided with the linear drive and possibly the locking mechanism, along a guide movable platform or cabin, for example, a lift, wherein the support points are provided along the path traveled by the transport element.
  • the transport element is a device for coupling a load to a crane, which device is connected to the linear drive via a train-loaded power transmission element.
  • the power transmission element ie, the steel cable, the chain, od.
  • Wound not wound on a drum, but possibly attracted or redirected by means of deflection or flaschenzugieri intermediate stages by the linear drive.
  • a particularly advantageous variant is characterized in that the linear drive moves along the tower and / or the jib of the crane.

  • the invention is not limited to such linear drives, so that at best also electrically operated worm drives or other types of linear drives can be used.

  • At least one locking mechanism may be present.
  • this support of the linear drive 3 can be held and secured in position at the respective support point 4 by the locking mechanism.
  • the locking mechanism When the locking mechanism is actuated, the respective supported linear drive 3 can not be released from the support point 4 and thus secures the means of transport 1 against falling.
  • the drive system of the transport means 1 is designed such that at least just before or when reaching the end position of the currently supported on a support point 4 linear drive 3 at least one far Linear actuator 3 is briefly moved in the same direction at the same speed, but with another support point 4 is brought into engagement.
  • a steady and uniform movement of the transport means 1 despite transfer of the drive effect between two different linear drives 3 can be achieved by an embodiment in which at least two counter-rotating linear actuators 3 emanating from a common base element, which in turn on the transport elements 1, i. the elevator car, the lifting platform, etc. is mounted. Shortly before or when reaching the end position of the currently supported on a support point 4 linear actuator 3, this base element is moved by means of another linear drive in the same direction as the currently supported and the transport means 1 driving linear drive 3. During this movement of the base member but is now also in the opposite direction, ie brought into the initial position for its working retracted linear drive with another support point 4 is engaged.
