Definitions
- the invention relates to an elevator with a highly eccentric to a support means set in a loose roll 2: 1 suspended car and with a drive formed at least from a motor, a traction sheave and a brake.
- a highly eccentrically suspended in so-called backpack suspension car is for example from EP 0706969 Bl, EP 1 024 105 AI, WO 99/33 742 AI, and JP 2000-7253, DE 195 46 590 C2 and DE 100 64 850 C2, A known.
- Carriages in rear suspension have the great advantage that they are accessible from three sides and are therefore very variable in buildings to be retrofitted with elevators.
- JP 2000-7253 and DE 100 64 850 C2 cabin and counter load are hung in a 1: 1 suspension pulley over a in the upper part of the shaft between an adjacent shaft wall and the car rear wall or the vertical extension of this area, by guiding the ropes over a traction sheave and struck directly on the car and on the counter load.
- This requires a powerful gearless drive.
- the cable guide is carried out so that from an upper rope stop the rope runs down, reverses on a permanently installed on the car deflection pulley, on the traction sheave again is guided downwards, reverses on a roller fixedly mounted on the counterweight and finally attached to the second end in the shaft head on a second cable stop.
- a 2: 1 suspension is realized, which in principle allows to use smaller, high-speed, gearless drives with an available half torque compared to a 1: 1 suspension.
- Such drives because the torque of a motor is proportional to the square of its diameter, can be accommodated more easily in a machine roomless shaft due to the smaller diameter of the drive.
- the invention is based on the object, starting from a 2: 1 suspension for baggage-driven cars, to offer an engine room-less installation of a gearless elevator drive for different cases of cramped shaft conditions.
- FIG. 1 shows schematically a first arrangement without a drive train in a drive shaft in an elevator shaft
- FIG. 2 is a schematic view of a further machine roomless arrangement of a drive in an elevator shaft
- FIG. 3 is a schematic view of a third arrangement without a drive train in a lift shaft.
- a support means set 2 fastened at both ends in the upper region of an elevator shaft 1 successively wraps around a counter-load deflection roller 4, a drive pulley 5 of the drive, an input pulley 6 of the drive arranged parallel to the axis of the drive pulley 5, again the traction sheave 5 and the counter pulley 6 of the drive and one attached to a support frame 7 for a car 8 in backpack suspension elevator pulley 9.
- the drive 5, 6 is formed of a non-visible gearless motor, a coaxial with the motor shaft or on a common shaft traction sheave 5, a brake device, not shown, which operates on the engine and / or the traction sheave 5, and the counter-disc 6 ,
- the motor is regulated with the aid of a frequency converter and, in normal operation, also takes over the braking and stopping of the elevator car 8.
- the counter disk 6 also serves as a deflection disk for the support means set 2 with respect to its guidance in the direction of the car deflection roller 9.
- the carrier or carriers for the drive 5, 6 are not shown in detail. They can rest on the guide rails 10 or in the masonry of the elevator shaft 1.
- a separate engine room is omitted by the drive 5, 6 is arranged with the traction sheave 5 and the counter disk 6 in the shaft head of the elevator shaft 1. If an engine room above the shaft head is present, of course, the drive 5, 6 are installed in this same way.
- the car 8 is fixedly connected to the support frame 7, which is guided in the guide rails 10 in the elevator shaft 1.
- the guide rails 10 are fastened in the example to an adjacent wall 12 of the elevator shaft.
- Parallel to the counter-load 3 is guided on the guide rails 10 in the elevator shaft 1. This is shown in plan view, with the discs 5, 6 and pulleys 4, 9 are not shown in the plan view to improve.
- Fig. 2 differs from Fig. 1 in that the drive 5, 6 is arranged steeper at an angle ⁇ and the car guide pulley 9 is not mounted above, but below the car 8 on the support frame 7.
- the car 8 in the elevator shaft can likewise be raised again, as in FIG. 1, up to a permissible minimum distance between the shaft ceiling and the car ceiling.
- the car deflecting roller 9 does not protrude in an advantageous manner to under the support frame 7, whereby no obstruction occurs when driving up to the buffers on the shaft bottom.
- the car deflecting roller 7 is rotated analogously to the counter-load deflection roller 4 in this embodiment.
- Fig. 3 the steep arrangement of traction sheave 5 and counter-disc 6 (angle ⁇ corresponding to FIG. 2) is maintained, but also the car-deflecting roller 9 is fixed to the top of the support frame 7 as shown in FIG. Unlike in Fig. 1 and Fig. 2, however, two pairs of guide rails are provided, namely a pair of guide rails 10 for the support frame 7 and a pair of guide rails 11 for a cross-sectionally approximately square counter load 3.
- the support frame 7 is in the space between the Guide rails 10, 11 pushed in, whereby the distance between the adjacent wall 12 of the elevator shaft 1 and the rear wall of the car 8 can be reduced to the space for the counterweight 3.
- the arrangement according to FIG. 3 is consequently particularly suitable for very narrow elevator shafts 1.
