Definitions
- the invention relates to a lifting device for lifting and lowering loads or heavy loads according to the preamble of claim 1.
- Lifting devices are used to raise and lower loads vertically in relation to a vertical direction. These can be operated both manually and motorized. In addition to manipulation in the vertical direction, such lifting devices usually also have the option of shifting in at least one transverse direction in order to be able to move loads in space. This can be done, for example, by rotating a boom of the lifting device and/or by moving it sideways.
- an otherwise stationary lifting device By combining it with a monorail, an otherwise stationary lifting device can also be moved along a structurally defined path. Arranged within a factory or on a factory premises or transhipment point, heavy loads such as loaded containers or entire vehicles can be moved safely.
- a lifting device was known in each case, which serves to lift and lower particularly heavy objects.
- Each of these lifting devices comprises two frame arrangements which are located one above the other in relation to a vertical direction and are in particular aligned or can be aligned parallel to one another.
- the lower frame assembly is suspended from the upper frame assembly via lifting and traction means in such a way that the lower frame assembly can be pulled up on the upper frame assembly by winding the lifting and traction means by means of a motorized lifting and lowering device, and by unwinding the lifting and traction means in relation to the upper frame assembly can be lowered.
- each of these lifting and traction means is deflected at least once in its extent. The deflection of the lifting-traction means takes place in such a way that a diagonal section of each lifting-tension means running inclined relative to the vertical direction crosses over with an immediately adjacent and oppositely inclined running diagonal section of another lifting-tension means.
- the present invention is therefore based on the object of further developing a generic lifting device in such a way that it enables at least limited active deflection control of its lower frame arrangement despite the use of the lifting traction means for lateral stabilization by means of deflection.
- the invention first proposes a course for each lifting and traction means in its own lifting and traction means level, with these lifting and traction means levels being oriented next to one another and parallel to one another.
- oblique traction means are provided, which in each case run in a side by side and parallel to each other and thereby oriented at right angles to the lifting traction means planes oblique traction means.
- the diagonal traction means can be wound up and unwound using a tensioning device.
- two directly adjacent oblique traction means are crossed with one another in such a way that the lower frame arrangement, opposite the upper frame arrangement, can be deflected in the first lateral direction and a second lateral direction, in particular running at right angles to the first lateral direction, transversely to the vertical direction is now also stabilized with respect to this second lateral direction in relation to the upper frame arrangement.
- the lifting and traction means both for transmitting the vertical forces resulting in particular from the absorption of a load between the frame assemblies and for stabilizing the lower frame assembly with respect to the first lateral direction, while the additional Serve oblique traction means of stabilization of the lower frame assembly with respect to the second lateral direction.
- the resulting advantage can be seen in the fact that the oblique traction means used for stabilization in relation to the second lateral direction can be controlled independently of the lifting traction means, so that the lower frame arrangement can be influenced at least to a limited extent if necessary.
- the lifting traction means are no longer switched in different directions steered, which increases their wear.
- the deflections themselves can also be made simpler for this purpose. With regard to the design of the lifting and traction means, they only have to be able to be deflected around one axis, which above all enables the use of belts and/or belts, which naturally have a greater width than their thickness.
- two lifting and pulling means can be deflected together on a deflection shaft located in the area of the upper frame arrangement to the lower frame arrangement.
- a common deflection shaft allows a deflection to be formed at any point on the upper frame assembly. The reason for this is that a deflection shaft only requires end bearings, between which it can also extend freely over greater distances.
- separate deflection rollers for example, each require their own storage, which always requires a corresponding proximity to the parts of the upper frame arrangement that are to be carried.
- each lifting and pulling means can be deflected towards the upper frame assembly at a deflection means located in the region of the lower frame assembly.
- a deflection means can preferably be a deflection roller.
- each of these lifting and traction means is connected to a men arrangement located deflection means is first deflected to a located in the region of the lower frame assembly deflection means and from there to a located in the region of the upper frame arrangement deflection shaft out.
- At least one of the deflection means can preferably be a deflection roller.
- Each lifting and pulling means can then preferably have at least one first vertical section extending between the deflection means located in the area of the upper frame arrangement and the deflection means located in the area of the lower frame arrangement, and at least one vertical section extending between the deflection means located in the area of the lower frame arrangement. tel and the deflection shaft located in the area of the upper frame assembly.
- the two vertical sections can enclose an angle of 0° to 4° between them.
- the respective lifting and traction means forms a loop-like shape, within which the lower frame arrangement can be supported via the respective deflection means.
- At least one of the deflection means mentioned can preferably be a deflection roller.
- each lifting-traction means can be fixed to the lower frame arrangement. End sections of the lifting-traction means opposite these free ends can then be coupled to a lifting shaft of the lifting/lowering device which can be rotated by a lifting drive.
- the lifting shaft is designed tet and set up that the lifting-traction at least partially around the lifting shaft around and can be unwound from this.
- each lifting and traction device can be fixed to the upper frame arrangement, while end sections of the lifting and traction devices opposite these free ends are connected to a lifting shaft of the lifting and lowering device that can be rotated by a lifting drive. Device are coupled.
- the lifting shaft is designed and set up in such a way that the lifting traction means can be wound up at least partially around the lifting shaft and can be unwound from it.
- the lifting and traction means are deflected together on a deflection shaft located in the area of the upper frame arrangement to the lifting shaft of the lifting/lowering device located in the area of the upper frame arrangement.
- the clamping device can have at least one clamping drive.
- This is coupled to at least one tensioning shaft, in which case at least two of the oblique traction means can then be wound up at least partially around the tensioning shaft and unwound from it.
- the tensioning drive can be mechanically independent of a lifting drive of the lifting/lowering device in order to enable the oblique traction means to be controlled separately from the lifting traction means.
- At least two tensioning shafts are provided around which at least two of the diagonal traction means can be wound up and unwound at least in part.
- these can be coupled at least indirectly either with their own or with a common tensioning drive.
- One tensioning drive per tensioning shaft has the advantage that these can be controlled separately from one another in order to manipulate the inclined traction means that are in contact with them.
- a common tensioning drive has the advantage that such a configuration requires fewer components and correspondingly less weight.
- the tensioning shafts can be coupled in a suitable manner to the one tensioning drive in a torque-transmitting manner, for example via at least one cardan shaft and/or a gear.
- the individual traction devices ie the lifting and/or inclined traction devices, can all be designed differently from one another or the same. All or at least individual traction means can thus preferably be a belt or strap or rope or a chain. Of course, combinations of these are also conceivable, which means, for example, the construction of an individual traction means from a belt and a rope. These can contain fibers made of metal and/or a plastic and/or a natural substance, for example, or be formed from at least one of these.
- the lifting device according to the invention has extremely advantageous properties with regard to the stability of the lower frame arrangement compared to the upper frame arrangement.
- the known tendency of such hanging constructions with regard to lateral deflections and/or rotational movements around a vertical direction is controlled according to the invention by deflecting the lifting and traction means that are necessary anyway in relation to a first lateral direction, while the additional diagonal traction means follow one of them allows independent control with respect to the transverse second side direction.
