AI Technical Summary

Problems solved by technology

Static loading, metal friction and similar influences on the carrier strip can change the magnetic currents and thus have a negative effect on the detection of the carrier and especially the traction carrier, which primarily transmits longitudinal forces
Relatively small magnetic currents are generated for thin traction carriers, which are difficult to detect reliably or accurately
Detection by measuring magnetic current is not possible if the traction carrier is made of non-metallic material

Embodiment Construction

[0052] The elevator system according to the embodiment of the present invention has Figure 2 to Figure 7 The carrier means 2 shown in detail in various embodiments is implemented in the form of a carrier belt with at least one traction carrier 2.1 for transmitting longitudinal forces, which is arranged in a carrier belt body 2.2 made of synthetic material.

[0053] Such as figure 1 As shown, the carrier belt 2 is fixed firmly (inertially) at the first fastening point 5.1, wherein an elastic suspension, represented by a spring, can be provided to compensate for load impacts. From there, the carrier 2 is guided around a first deflector wheel 6 on which the counterweight 3 is suspended. The carrier is guided from the first deflecting wheel via at least one drive wheel 7 to the two further deflecting wheels 6' and is fastened with its other end firmly to the second fastening point 5.2. The elevator car 1 is fixed on the above-mentioned other reversing wheels 6'. The carrier me...

Abstract

The invention relates to an elevator system having an elevator cabin (1), a load carrier (2) for holding and / or moving the elevator cabin (1), and a detector device (8.1, 8.2, 8.3) for detecting a condition of the load carrier (2), the detector device (8.1, 8.2, 8.3) having an ultrasonic emitter (8.1) for generating and coupling ultrasonic waves (8) into the load carrier (2) and for generating ultrasonic waves (8) in the load carrier (2), and an ultrasonic receiver (8.2) for detecting ultrasonic waves (8, 8') of the load carrier (2).

Description

technical field [0001] The invention relates to an elevator system with an elevator car, a carrying mechanism and a detection device for detecting the state of the carrying mechanism, and also relates to a method for detecting the state. Background technique [0002] The elevator car is moved, ie raised and lowered, in the elevator shaft or along separate guides by force transmission mechanisms. Therefore, in order to reduce the necessary lifting force, the weight of the elevator car can be partially balanced by a counterweight, which is connected to the elevator car by means of a connecting mechanism. The force transmission mechanism and the connection mechanism can be formed separately. Preferably, however, the traction force for raising and lowering the elevator car is transmitted via the same transmission mechanism, via which the elevator car is also connected to the counterweight. Not only such special force transmission or connection means but also such transmission ...
