Definitions

  • the present invention relates to a method and a device for detecting damage in a suspension element with at least one tension member for an elevator installation.
  • Elevator systems typically have at least one car that can be moved between floors.
  • the car is generally moved along an elevator shaft with the aid of a rope-like or belt-like suspension element.
  • a counterweight can be provided which is also suspended from such a support means that the counterweight moves in the opposite direction to the cabin.
  • the suspension element In the course of the operation of the elevator system, the suspension element is repeatedly bent and / or flexed, for example by repeated deflection on deflection rollers or the traction sheave, and is thus heavily mechanically loaded.
  • damage or wear within the suspension element In order to be able to reliably prevent tearing or breaking of the suspension element due to such mechanical loads and a possibly associated fall of the car or the counterweight, damage or wear within the suspension element must be reliably detected in good time.
  • the suspension element can be, for example, a belt, a rope or the like.
  • the suspension element normally has a plurality of electrically conductive metal tension members and an electrically insulating jacket, which normally consists of a plastic material or a polymer, which encompasses tension members from the outside and can protect them against corrosion or mechanical wear.
  • a determination or monitoring of an electrical resistance or an electrical conductivity of a suspension element or tension member was recognized in principle as a possibility of detecting damage in the suspension element.
  • WO 2014130029 A1 describes a method for detecting damage in a suspension element of an elevator system, in which at least part of the suspension element is exposed to an electrical alternating voltage and an electrical impedance is measured in this part of the suspension element, which can be used to infer damage states in the belt or rope.
  • WO201230332 discloses a monitoring system for a support means, the monitoring system comprising a circuit and a resistance circuit in order to be able to couple to the support means.
  • the resistor circuit has a first and a second group of resistors, the second group of resistors being configured to be able to provide a reference voltage.
  • a comparator can compare a voltage across a resistor with the reference voltage and consequently generate an output signal.
  • the circuit monitors an effective resistance of the suspension element with regard to the output signal
  • the invention is based on the object of being able to monitor a suspension element of an elevator system, which has at least one electrically conductive tension member, in a simple and safe manner.
  • this object is achieved by a method with the features of claim 1 or a device with the features of claim 11.
  • the invention is based on the idea of detecting damage within a suspension element with the aid of its signal transmission capability.
  • damage which could occur in the form of cracks or breaks in the suspension element, for example, is usually associated with a change in the signal transmission capability within the suspension element caused by the damage.
  • a / D converter an electrical analog signal can be converted into an electrical digital signal with a certain time discretization (sampling) or period duration.
  • a digital signal converted in this way oscillates between two different ones Signal levels or logic levels, a high level and a low level, with a set constant signal frequency, the high and the low level usually being represented by a logic function of a logic one "1" or a logic zero "0".
  • An electrical digital signal can thus be encoded as a binary number so that its quantization can be specified in bits.
  • a method for detecting damage or defects in a suspension element with at least one tension member for an elevator installation is specified.
  • the suspension element can be, for example, a belt, a rope or the like.
  • the tension member consists of an electrically conductive material such as steel or another metal.
  • At least one electrical digital input signal is generated by a pulse generator.
  • the digital input signal can represent at least a first binary number.
  • a so-called binary number means that it is represented by one or more logical ones and / or logical zeros and thus consists exclusively of the number "1" and / or "0".
  • the digital input signal can be assigned to the at least one tension member so that this tension member can be checked by means of the digital input signal or the first binary number.
  • the digital input signal is fed to the tension member.
  • the digital input signal After the digital input signal has passed through the tension member, it is detected as a digital output signal, e.g. by means of a detector, the digital output signal also representing at least a second binary number.
  • the pulse generator (9) and the detector (10) can be clocked or operated with the same frequency and period.
  • the second binary number is then compared with a desired binary number and / or directly with the first binary number, in particular compared in places or bits.
  • the binary nominal binary number can, for example, be specified as a constant value or it can be generated dynamically using a current digital input signal. Damage in the tension member is determined on the basis of an issued comparison result. If the second binary number deviates from the nominal binary number and / or from the first binary number, an error message is generated.
  • the error message can be in different forms and sent to a control device of the elevator system or to a monitoring center and / or maintenance center, that are removed from the elevator system.
  • this monitoring is carried out digitally in a simple manner, without having to measure fault-prone factors such as electrical resistances or voltages.
  • At least one analog electrical signal is generated by a signal source such as a voltage or current source, the signal source serving as a signal generator.
  • the analog electrical signal e.g. a current or a voltage
  • the level height and the pulse length of the pulse depend, for example, on the length, the diameter or the material of a tension member.
  • the signal source can be a direct voltage or direct current source, but also an alternating voltage or alternating current source.
  • the method according to the invention can advantageously be carried out for the tension member or members of the suspension element individually, in part, or all of them.
  • the tension members can be grouped into at least one group if the suspension element has two or more tension members. Then the method can also be carried out for the tension members of the group individually, in part, or all of them. In the case of two or more groups of tension members, this method can also be carried out either separately for a single group or for two or more groups at the same time.
  • the at least one group can have an identical or different number of tension members.
  • the total number of tension members of the suspension element corresponds to twice or more than a number of tension members in the group.
  • a belt is used in such a suspension element.
  • tension members are included as a core in a jacket of the belt.
  • a belt typically includes 12, 16, 20 or 24 tension members.
  • the first binary number is a four-digit binary number for all groups or Tension member.
  • the digital input signal is generated in such a way that the total number of digits or the number of bits of the first binary number is equal to or greater than the number of tension members of the suspension element or group.
  • a first binary number such as 0001, 000001 or 100010 can be formed if a group comprises only four tension members.
  • the first binary number has at least one first special digit.
  • This first special position can be filled with a number "1", for example, but also possible with a number "0".
  • the first special places of all first binary numbers can be positioned differently from one another and, in particular, offset from one another.
  • the first binary numbers can thus represent or show different tension members in a group or in the suspension element.
  • the first binary number has only a first special position at which there is either a digit “1” or “0”.
  • the first binary number such as 0001, 0010, 0100 or 1000 can be formed if a group includes, for example, four tension members.
  • the order of the digit "1" in the first binary numbers can also correspond to an order of the tension members of the group.
  • a first binary number the binary number of digits of which is more than the number of tension members of the group or of the suspension element, can also have a corresponding number of first special positions, at least one of which can determine an individual tension member.
  • the first special positions can be filled with digits "1" and / or "0" as required.
  • the second binary numbers can add up to one another.
  • a sum resulting therefrom is evaluated to determine damage in a tension member or the tension members in a group by comparing the sum with the stored nominal binary number and / or with the first binary number.
  • the detection method for a group or for the suspension element can even be carried out only once, so that all tension members of the group or of the suspension element are already detected or checked. If every first binary number only has a first special position with a digit "1" and these positions are offset from one another, and only in all other binary positions of the first binary number Digit "0", a resulting sum of all first binary numbers should have a number of digits "1" equal to the total number of the tension members tested. That means a normal condition of the suspension element.
  • the resulting sum is therefore to be defined as a special value if the first and / or the second binary number have a different period duration or different numbers of digits. That is, if the total has a different number of digits "1" or is a special value, this means that the suspension element is in a faulty state. Depending on how many and which binary points, where there is no digit "1", it can be evaluated how many and which or which tension members are damaged.
  • the first binary number has at least one second special position which can represent or show a specific group, a binary value remaining unchanged at the second special position.
  • the second special position can also be generated separately from the first binary number, i.e. the second special position can be represented by an independent binary number that represents a specific group.
  • the electrical digital input signal can represent at least one first binary number.
  • the input signal can be applied to a first connection of the tension member.
  • the device has a detector for detecting an electrical digital output signal, wherein the output signal can also represent at least one second binary number.
  • the digital output signal is considered to be a digital input signal transmitted from the first connection through the tension member to the second connection.
  • the device also has a processor for comparing, in particular for comparing digit by digit or bit by bit, the second binary number with a nominal binary number and / or directly with the first binary number.
  • the processor can evaluate an output comparison result.
  • the device also has an error message for generating an error message if the second binary number deviates from the first binary number and / or from the nominal binary number.
  • the device can be connected to at least one signal source such as a voltage source and / or a current source, wherein the signal source can generate an analog electrical signal.
  • a signal source such as a voltage source and / or a current source, wherein the signal source can generate an analog electrical signal.
  • the desired binary number can advantageously be specified as a constant value or can be generated dynamically by the processor on the basis of the current digital input signal.
  • the pulse generator and the detector can be operated or clocked with the same frequency and period duration, so that a synchronization between the two devices or between the signal transmission and reception occurs.
  • the method and the device are event-controlled, manually and / or automatically carried out or activated when the elevator system is out of operation, for example in a maintenance or installation state, or in a waiting period (standby).
  • An event can be triggered both externally, for example by a user input or a technical value, and by the device itself (for example change notifications).
  • An electrical contact point at which the suspension element or its tension member can be electrically contacted for measurement can be, for example, any deflection roller, wherein the deflection roller can be a deflection roller fixedly arranged in the elevator shaft or also one of the deflection rollers of the counterweight or the elevator car .
  • the contact point can therefore be a sliding contact or a contact point which is arranged, for example, at a short distance from the suspension element.
  • This contact can be any part of the elevator system that the suspension element is guided past.
  • An example of this is a so-called retainer, i.e. a derailment protection system, which deflection pulleys usually have.
  • support rollers of the counterweight or the elevator car and, in principle, the traction sheave as well as metallic shaft components can also be considered.
  • the contact point can be a metallic surface that is coated, for example, with a highly conductive material such as copper or brass.
  • Brush contacts for example in the form of carbon fiber brushes, copper brushes or the like, can also be used.
  • the use of brushes has the advantage that the brushes nestle against a surface of the suspension element, i.e. they follow a contoured or shaped surface exactly, so that the entire surface is covered.
  • the contact point is conductive and can advantageously be grounded - if the monitoring device is operated with direct current - or a voltage can be applied to the contact point - if the monitoring device is operated with alternating current - and basically a contact to the conductive part or the conductive parts of a suspension element is possible if this conductive part of the suspension element comes into contact with this contact point.
  • This last-mentioned contact between the contact point, for example the pulley, and the conductive part or parts of the suspension element can arise, if, for example, individual tension members break and subsequently pierce through the sheath. These broken tension members graze along the contact point and thus establish electrical contact during the contact time.
  • an interruption in a tension member, a transverse or short circuit between tension members or damage to the sheathing or piercing of individual tension members can be determined.

  • An analog electrical signal 6 is generated by a signal source such as a direct voltage or direct current source 16.
  • a pulse generator 9 then enables analog signals to be converted into digital signals.
  • the analog electrical signal 6, for example an appropriate current or an appropriate voltage is converted into a digital electrical input signal 4 or in the form of a first binary number 4B.
  • the pulse generator 9 can be an A / D converter or generate an adjustable basic cycle for pulse trains, ie adjustable pulse group train periods.
  • the pulse generator 9 can possibly be designed as a pulse width modulator (PWM) so that the input signal 4 can also be generated in the form of a pulse sequence and the pulse amplitude or signal level or the pulse width as required can be set flexibly.
