    Means of transport for loads or persons
    The invention relates to a means of transport for loads or persons, with at least one transport element for the persons and / or loads or for coupling the load, as well as a drive system for the transport element.
    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.
    It was the object of the present invention to provide a means of transport with a smaller footprint.
    To solve this problem, the transport means described above is characterized in that the or each transport element is provided with at least one linear drive, which indirectly or directly exerts a drive torque on the means of transport in at least one working direction. Linear drives can be made very narrow, so that when installed substantially parallel to the direction of movement of the transport elements little additional space is consumed.
    According to a first embodiment of the invention, at least one linear drive and at least one locking mechanism is provided for the or each transport element, wherein the linear drive is supported on support points and during the working stroke exerts a drive torque on the transport element, and wherein the locking mechanism between individual working strokes with support points in engagement can be brought. About the linear drive, the transport element, i. the lift cabin or the lifting platform, gradually raised or lowered. For the time of retraction of the linear drive in the starting position of a new working stroke, the transport element is secured by the locking mechanism, which is released during the working stroke.
    In a further development of this embodiment, 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 exert a drive torque on the transport element during its working stroke, wherein at least one linear drive of a support point is supported at any time. With such a construction, a substantially continuous movement of the transport element, without disturbing in particular passenger transport stop phases, can be ensured.
    Preferably, it is provided that 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, the support points are provided along the traversed by the transport element path.
    Another embodiment of the invention provides that 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. In this embodiment, the power transmission element, i. the steel cable, the chain, od. The like., Not wound up on a drum, but optionally attracted or diminished by diverters or flaschenzugartige intermediate stages by the linear drive.
    In this case, a particularly advantageous variant is characterized in that the linear drive moves along the tower and / or the jib of the crane.
    As a linear drive for a conveyor according to the invention can advantageously be provided fluidic cylinder or electric linear actuators. However, 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.
    In the following description, the invention will be explained with reference to the attached drawings with reference to some Ausführungsbetspiele.
    1 shows a schematic representation of a lift cabin as a conveyor according to the invention with two lateral linear drives, and FIG. 2 is a similar view in which worm drives are used as an alternative.
    An elevator car 1 or lifting platform as a means of transport for persons and / or loads is movable along a vertical or even mixed vertical / horizontal guide 2, which can be designed as a rail, mast, etc. The or each conveyor 1 is provided with two linear drives 3, which are mounted on the conveyor 1 and apply the driving force for raising or lowering the car 1. Thus, a liquid, uniform movement of the car 1 is possible without disturbing stop phases between the individual working strokes of the linear drives 3, since the linear drives 3 can be alternately supported on the support points 4 along the guide 2, wherein at any time at least one linear drive 3 on a support point is supported and thus ensures safety.
    If only one linear drive 3 is provided, it is additionally necessary to provide at least one locking mechanism. About the linear actuator 3, the transport element 1 is then gradually raised or lowered, with the transport element 1 is held and secured by the locking mechanism between the individual working strokes. at
    KH-3383 AT 3 actuated locking mechanism, which may be formed for example by a laterally extending working cylinder, which can be preferably engaged with at least one of the not used by the linear drive 3 support point 4, is the retraction of the drive 3 in the starting position for a new Working stroke possible. Of course, separate arrangements of support points 4 can be provided for the drive and the backup.
    In Fig. 1 3 hydraulic cylinders with extendable piston rods are exemplified as linear actuators, wherein at the end of the piston rod an arrangement is provided which allows temporary support at a support point 4, for example, an automatically actuated pawl, a fluidic Arbeitszyiinder od. Like. As linear actuators In addition to the above-mentioned hydraulic cylinders and other fluidic working cylinders, electrical or other types of linear drives can also be used.
    For example, FIG. 2 shows an embodiment according to the invention with two worm drives which are connected to the transport element 1. Over at least part of the height of the elevator car 1, two threaded spindles 5 extend parallel to the guides 2 on the outside thereof. Supporting points 4 are provided on these guides, which engage in the thread of the threaded spindles 5.
    Upon rotation of the threaded spindles 5, a driving force between the support points 4 and the transport element 1 is generated, which can advantageously be adjusted by the pitch of the threaded spindle 5 to the intended load of the transport element 1. In order to keep the components of the drive force not serving the drive of the transport element 1 as low as possible, the ends of the support parts engaging in the threaded spindles 5 can be provided with friction-reducing devices, for example rollers, roller or ball bearings, corresponding friction-reducing coatings or the like ,
    The drive (not shown), by which the threaded spindles 5 are rotated, may be a conventional drive, preferably an electric motor.
    Yet another embodiment of the invention provides that the transport element is a device for coupling a load to a crane. Thus, in the context of the subject invention, a crane hook or similar device on cranes, hoists od. Like. Considered as a transport element, which hook or which device to the coupling of a load on the crane and serve in their movement through the drive system of the crane and the coupled load is transported. Usually, the said hoists are provided with train-loaded power transmission elements to which the load hangs. According to the invention, this power transmission element, i. • ·
    KH-3383 AT 4 a steel cord, a chain, od. Dg!., Not by means of a driven drum off or wound, but is optionally tightened or redirected by diverters or flaschenzugartige intermediate stages by the linear drive in a substantially straight line. Dabet moves the linear actuator advantageously along the tower and / or the boom of the crane or hoist.
