Definitions
- the invention relates to a scissor lift table with one between one
- Such a scissor lift table for lifting and lowering loads is specified in DE 90 05 566 U 1.
- a load-bearing platform is raised or lowered by means of two scissors 30 arranged laterally parallel to one another by opening and closing the scissor legs.
- the scissors are opened and closed by means of a lifting carriage or lifting carriage, which is moved back and forth between the lateral longitudinal struts of a base unit.
- the pallet truck has sloping on its top Lift curves, which interact with rollers arranged in the area of the scissors axis for lifting and lowering the platform.
- the lifting carriage is moved by a drive via a threaded spindle.
- a spindle is a precision part and usually runs in a spindle nut with ball bearings.
- Such a spindle drive is relatively expensive and also sensitive to transverse forces and vibrations, so that the run can be disturbed and the spindle drive can be damaged.
- the invention has for its object to provide a scissor lifting table of the type mentioned, with which a reliable, controlled lifting movement is achieved.
- the drive can be used to drive a stationary drum directed parallel to the scissors axis, with which at least one band-shaped traction means placed around it and coupled to the pallet truck can be moved, and that the band-shaped traction means for opening the scissors by pulling the Pallet truck in the direction of the scissors axis can be wound onto the drum by means of the drive and can be unwound from the drum in the opposite direction away from the scissors axis by the movement force of the pallet truck in order to close the scissors.
- One construction variant is that the lifting truck is arranged on the side of the scissors axis facing away from the drum, another one that the lifting truck is arranged on the side of the scissors axis facing the drum and the traction means is guided over a deflection roller.
- the lifting movement can be influenced in the desired manner in that the lifting carriage is guided over lifting curves arranged on lower leg sections of one pair of legs or on upper leg sections of the other pair of legs or on the leg sections of both pairs of legs.
- a constant lifting load can also be achieved in this way, the tensile load in the band-shaped traction means remaining constant in all lifting positions.
- the stroke curves are adjustable and / or interchangeable.
- drum is arranged on a lower fixed pivot axis of one pair of legs or outside the same. If the fixed swivel axis is used for drum storage, additional bearing elements are saved. On the other hand, an arrangement outside the pivot axis can be favorable for maintenance or the belt guidance under certain circumstances. 5
- the measure that the drive has a frequency-controlled electric motor results in a favorable drive control, with both high lifting speeds and very precise stroke positioning being achieved.
- the drive has a braking device for controlled lowering of the carrier.
- a further safety factor is that a safety gear against uncontrolled lowering is provided.
- the figure shows a side view of a scissor lift table with a platform or a carrying device for receiving a load.
- the carrying device has lateral supports 10 on which the upper ends of a first and a second pair of legs 1, 2 are articulated. The left leg ends of the second
- Pair of legs 2 are mounted, for example, on a fixed pivot axis, while the right leg ends of the first pair of legs 1 are displaceable in the carriers 10 on rollers or journals and are pivotably mounted, as is known per se.
- the lower leg ends are mounted in side rails 11 of a base unit, the left lower leg ends of the first pair of legs 1 being slidably mounted on a fixed pivot axis and the right lower leg ends of the second pair of legs 2 or on rollers and being pivoted on the rail 11.
- the two pairs of legs 1, 2 are pivotally connected to each other on a scissors axis 6.
- a lifting truck 3 is mounted displaceably or displaceably between the mutually facing sides of the first and second pair of legs 1, 2, wherein between the edges of the pair of legs 1 , 2 suitable lifting curves 8, 9 are arranged to influence the movement or the lifting load, on which the lifting truck 3 is guided.
- the pallet truck 3 is pulled towards the scissors axis 6 by means of one or more adjacent drawstrings 4 for lifting the carrying device or opening the scissors, the drawstring or 4 being pulled by means of a drum arranged with respect to the pallet truck 3 on the other side of the scissors axis 6 5 are wound, which is coupled to a drive 1 2.
- the lifting truck 3 moves away from the scissor axis 6 under the load of the scissor lifting table, the drawstrings 4 unwinding from the drum 5.
- the drive 1 2 or a transmission of the same can act as a braking device or an additional braking device can be provided.
- the lifting carriage 3 can also be arranged on the same side with respect to the scissor axis 6 as the drum 5 mounted parallel to the scissor axis 6. In this case there is one on the side of the scissor axis 6 facing away from the drum 5 or the lifting carriage 3 To provide pulley.
- the drive 1 2 preferably has a frequency-controlled electric motor, with which both high lifting speeds and highly precise stroke positioning gen can be reached.
- the start-up and the movement sequences can be programmed by means of a corresponding control device, and in particular the start phase and the end phase of the movements can also be programmed for a smooth start and stop.
- the drum 5 can be mounted on the fixed pivot axis 7 or separately from it.
- a catching device that is effective in the case of a rapid downward movement is advantageous.
