Definitions
- the invention relates to an elevator with at least one compensating means, which is arranged between an elevator car and a counterweight and serves to balance the weight of a suspension element, wherein the compensating means is guided by means of a guide device and a linear part, a loop part and a curved part and wherein the loop portion and the curved portion together have a parabola-like shape.
- a means for balancing the weight of a support means is provided.
- the suspension element is guided over a traction sheave, which in turn can be driven by means of an elevator drive.
- an elevator car is arranged and at the other end of the support means a counterweight is arranged.
- the elevator car and the counterweight can be moved in opposite directions by means of the suspension element in an elevator shaft, the elevator car serving floors.

- a compensating means is provided, which is arranged at one end at the bottom of the elevator car and at the other end at the bottom of the counterweight. For example, if the carrier length on the counterweight side is large, the compensating means length is small on the counterweight side and large on the cabin side. The weight shift on the part of the support means is compensated by the counteracting compensation means or
- the drive torque, the braking torque and traction on the traction sheave can be optimized.

- the compensating means thereby has between the counterweight and the first guide means on a first linear part and between the
- Elevator car and the second guide means on a second linear part Between the two linear parts forms a semicircular loop. Learns that
- the loop apex moves up and then down again.
- a sensor is provided which monitors the upper tolerable deflection of the loop vertex.
- Another sensor is provided outside (below) the loop. If the loop releases the sensor, the elevator system is shut down.
- a disadvantage of the known device is that the elevator system is stopped even with small loop movements.
- the proposed device solves the problem of avoiding the disadvantages of the known device and to provide a monitoring that is more tolerant of deflections of a compensating means and still ensures the safety of the elevator system.
- loop movements turn off the elevator system only when the loop movements for the
- Compensating and for the shaft equipment assume a potential with destructive power. After the shutdown of the elevator system, the elevator car and the counterweight has inertia due to a caster. The proposed device takes account of this caster without causing damage immediately after the shutdown.
- the proposed device is suitable for a compensating means with a linear part, preferably on the counterweight side, and a bent part, preferably on the
- Cabin side A guide device arranged, for example, below the travel path of the counterweight and centrically to counterweight guide rails guides and dampens the compensating means, in particular on the counterweight side. Between the guide device and the elevator car, the compensating means assumes a parabolic-like shape with a loop part and a weakly curved part.
- the loop part increasingly diminishes and moves ever closer to the guide device.
- a comparable state can occur even with strong vibrations in the compensating means. Without timely shutdown of the elevator system at least the guide device would be damaged.
- the proposed device is based on

- the support means 5 is guided over a traction sheave 6 and a deflection roller 7, wherein the traction sheave 6 is part of a arranged in a machine room 8 drive 6.1.
- An elevator installation 1 without an engine room 8, in which the drive is arranged in the elevator shaft 4, is also possible.
- a 1: 1 support means guide is shown.
- Other support means guides are also possible.
- the elevator car 2 stands on a top floor 9, while the counterweight 3 is above a shaft pit 10. In this situation, the elevator car 2 and the counterweight 3, the support means 5 on the cabin side is short and on the
- a guide device 12 which is the
- Compensating means 11 leads in particular on the counterweight side and attenuates vibration. Between the counterweight 3 and the guide device 12 forms the
- Compensation means 11 linear or has a linear part 11.1.
- Guide device 12 and the elevator car 2 takes the compensation means 11 a parabolic-like shape with a loop portion 11.2 and a slightly curved portion 11.3.
- FIG. 2 shows a side view of the guide device 12 and a monitoring device 13 with a detection region 13.8 for the compensating means 11 during normal operation.
- the detection range 13.8 is selected so that tolerances of the device and the assembly and structural deviations are taken into account.
- the compensating means 11 is guided by means of the guide device 12, for example by means of a roller guide.
- the course of the compensating means 11 is, as explained above, from the counterweight 3 to Guide device 12 linear and parabolic from the guide device 12 to the elevator car 2.
- a console 16,17 is arranged for the monitoring device 13 each.
- FIG. 3 shows a top view of the guide device 12 and the monitoring device 13 for the compensating means 11 during normal operation. From the counterweight 3 to the guide device 12, the compensating means extends in a first, through the guide rails 14, 15 of the
- Guide means 12 consists for example of four, the compensating means 11 enclosing rollers 12.1. From console 16 to console 17, a line 13.1 is stretched, which penetrates a second, spanned by the compensating means 11 level E2 approximately at right angles and is arranged above the loop portion 11.2.
- the line 13.1 is, for example, rope-like
- the leash 13.1 can also penetrate the second plane E2 obliquely, if the counterweight 3 is arranged off-center or in a shaft corner.
- FIG. 3 further levels E2.1 and E2.2 are shown, which are each spanned by a compensating means for the case that two compensation means 11 are provided between the elevator car 2 and the counterweight 3.
- the line 13.1 also penetrates the second planes E2.1, E2.2 obliquely and can be actuated simultaneously by one or both compensating means 11.
- the line 13.1 is fastened to the second bracket 17 and resiliently mounted on the first bracket 16 in the line longitudinal axis, wherein at a caused by the loop portion 11.2 deflection of the line 13.1, a cam 13.2 is moved in the line longitudinal axis.
