Definitions
- the invention relates to a scissor lifting device with at least two pairs by one Pivot axis connected scissor members, the pivot axis between the respective End sections of the scissor links is arranged, and with a drive for erecting and lowering the scissor members by means of a traction device.
- Such a scissor lifting device is the subject of DE 100 24 075 A1, for example.
- the traction means the distance between the upper or lower ends the scissor links changed.
- the traction means with one end of one of the scissor links and by means of a deflection roller at an upper end of the other scissor link connected to the drive and thus retractable.
- the traction means acts on an expansion body, that in the lowered rest position of the scissor lifting device near the lower one End of a scissor link between this and the overlying upper end of the other Scissor link lies.
- the traction means is not wound up by means of the drive, but has one of them Loop closed end section so as to prevent the traction device from sliding off.
- a disadvantage of such scissor lifting devices is their lifting height of an expansion body is varied so that the lever ratios in the lowered rest position differ significantly from the raised working position.
- the one for change The forces required for the lifting height differ in the two extreme positions by a multiple. In practice, this leads to signs of wear. It will also large drive power required. It is also necessary to move the To influence the spreading body with the help of a complex control such that the lifting speed between the extreme positions is almost constant, at least is not subject to undesirably high fluctuations.
- US Pat. No. 4,858,888 also discloses a scissor lifting device in which the free end of the support arm is guided by an angled guide arm, which is also articulated to the first scissor link.
- the invention has for its object to provide a way to a scissor lifting device of the type mentioned at the outset in such a way that the operations required Drive power is significantly reduced. Furthermore, the scissor lifting device should be low Effort to be adapted to different purposes.
- the scissor lift device has at least one coupling bridge with two by means of a joint pivotably arranged struts, each with one Scissor link are pivotally connected, the coupling bridge a pulley for the traction device defined on the scissor lifting device.
- the coupling bridge is included the pulley, so that by applying the tensile force the distance and thereby at the same time the lifting height can be changed with little effort. Because of this Realizable favorable leverage ratios become the peak load to be applied by the drive, especially when lifting from the lowered rest position, significantly reduced. This also results in significantly less wear, because the deflection the traction device is only subject to very low friction losses. Furthermore, it shows that due to the changed force application an almost constant ratio between the Differential length of the traction device and the difference in lifting height can be realized, which the Control effort is significantly reduced.
- the scissor lift device also allows easy adaptation to different application conditions, by using larger ones Load requirements only the traction device must be replaced. Cumbersome new designs can be avoided in many cases.
- the free end of the traction device can be fixed on the swivel axis.
- a special one practical embodiment of the present invention is also achieved by that the scissor lifting device is arranged on both sides of the pivot axis Has coupling bridge, the first coupling bridge with at least one deflection roller and the second coupling bridge is equipped with a fixation for the traction means. hereby is a considerably more uniform force transmission into the scissor links by the two opposite coupling bridges reached by means of the respective push struts and thereby increases operational safety and, at the same time, stresses individual push struts reduced.
- a particularly advantageous development is also realized in that the pivot axis and the coupling bridges in a common, in particular horizontal, plane are arranged. This achieves a uniform stroke movement and at the same time Fluctuations in the required drive power between the extreme positions of the scissor lifting device reduced.
- the tracks which are in particular guided parallel to one another, could be in a common in particular by the plane determined by the pivot axis.
- the deflection of the traction means takes place even when it is stationary outside the scissor lift device positioned drive for the traction mechanism only in one level.
- the resulting load on the traction device as well as wear and tear are significantly reduced.
- An embodiment of the invention has also proven to be particularly advantageous Scissor lifting device in which the push struts have a matching distance between have the coupling bridge and the respectively associated scissor link. hereby the orientation of the coupling bridge, unlike the principle of parallel program guidance, is unaffected from the room position depending on the lifting height. The path of the Traction means is therefore constant over the entire lifting height.
- the traction means can for example be a plastic or wire rope, a chain or a wedge or Toothed belt must be executed.
- an embodiment is particularly practical which the traction means is designed at least in sections as a webbing.
- the webbing combines high flexibility and tensile strength and also requires no lubricants. Furthermore, the webbing can be used and permitted without disturbing operating noises a flat overall height.
- a particularly versatile embodiment of the invention is also achieved by that the scissor lifting device by means of further paired scissor links is modularly expandable. This allows double or tandem constructions with little effort be realized, which are operated by a single common traction can be. A control effort required for one according to the prior art synchronous movement is therefore no longer necessary. If several traction devices are used, can, according to a further advantageous embodiment, in particular by means of a common drive can be actuated.
- Another particularly promising embodiment of the present invention is achieved in that the two coupling bridges by means of one to adapt to different Lifting heights of continuously variable guide elements connected to each other are.
- This guide element which is in particular telescopic, is limited the relative mobility of the two coupling bridges to one another to only one degree of freedom, so that only the distance between the two coupling bridges is variable. The orientation the coupling bridges are therefore immutable.
- the guide element as a damper or emergency actuator is carried out, in the event of a sudden strain relief, an unintentional lowering to avoid the lifting device.
- a hydraulic cylinder equipped guide element damping Load changes.
- the drive can be arranged spatially separated from the scissor lifting device. However, an embodiment is also particularly compact if the drive is on the coupling bridge in one determined by the joints of the push struts and the swivel axis Level is arranged. Several drives can each be assigned to a coupling bridge and be arranged opposite each other.
- Scissor lift device reached when the drive with a winding drum for the Traction means is connected, which is determined in particular by the number of windings Coil diameter determined as a function of the material thickness of the traction device is that a constant rotation speed of the winding drum leads to a constant change in the Lifting height of the scissor lifting device leads to a uniform one without speed control To realize stroke movement.

- the coupling bridges 14, 15 by a guide element acting as a damper, in particular realized by a cylinder 24 connected so that load changes do not lead to undesirably high peak loads.
