Definitions
- the present invention relates to a device and a method for monitoring at least one suspension element in an elevator installation.
- a test current can be applied to the tension members.
- a current flow or a current, a voltage, an electrical resistance or an electrical conductivity is measured. On the basis of a size measured in this way, it is possible to conclude that the tension members of the suspension element are intact.
- the publication DE 3934654 AI discloses such a device or such a method for determining a state of the tension members of a belt-like suspension means. Based on a circuit in which all the tension members of the suspension element are connected in series, it can be determined in a simple manner whether at least one of the tension members is interrupted or not.
- an elevator system is first proposed with a suspension, wherein the support means comprises a plurality of parallel in a common plane juxtaposed electrically conductive tension members, which are electrically isolated from each other, and which are surrounded by a common jacket. In this case, all the tension members of the suspension element in a circuit are electrically interconnected.
- This circuit comprises a current or voltage source and a measuring device.
- the measuring device is arranged between a first group of tension members and a second group of tension members, so that electric current first flows from the current or voltage source through the first group of tension members, then through the measuring unit and finally through the second group of tension members back to Current or voltage source flows.
- the tension members of the first group of tension members and / or the tension members of the second group of tension members are interconnected in series.
- This device has the advantage that various states of the suspension element can be reliably detected by such an arrangement of a circuit. First, it can be determined whether one or more of the tension members of the suspension element are interrupted. The measuring device can determine in a simple manner, whether substantially current flows through the circuit or whether substantially no current flows through the circuit.
- each tensile member of the first group is directly adjacent only by tensile members of the second group, and each tensile member of the second group is directly adjacent only by tensile members of the first group.
- the proposed device in addition to detecting an electrical Contact of directly adjacent tension members can also be detected if two non-adjacent tensile carriers of different groups of tension members are electrically connected to each other via a further electrically conductive element. This can occur, for example, when the jacket of the suspension element is damaged, and the two not directly adjacent tension members of different groups of tension members are guided at the damaged point via an electrically conductive pulley, for example a deflection pulley on the counterweight. Also in this case, the circuit is shortened so to speak, so that on the measuring device in a simple manner, a significant drop in the current or the voltage can be determined.
- this device Since in the proposed device, no precise values must be determined by the measuring device, this device is very robust against disturbing influences such as temperature fluctuations, electromagnetic radiation, movements of the suspension means and the like. A change in state of the suspension element results in a marked change in the current intensity or the voltage or the electrical resistance in the measuring device. Thus, it only has to be determined whether a determined value is above or below a predefined limit value.
- the first group of tension members and the second group of tension members comprise the same number of tension members.
- the measuring device is designed as a current measuring device or as a voltage measuring device. Depending on whether a current or a voltage source is used, a current measuring device or a voltage measuring device can be selected as the measuring device.
- the current or voltage source is designed to generate an alternating current or a direct current.
- the circuit further comprises an isolation monitor.
- an isolation monitor This has the advantage that thereby a further state of the support means can be monitored.
- a ground fault may occur to a grounded object in the elevator installation.
- an exposed tensile beam or a protruding the wire make electrical contact to a drive pulley or a Umlenkpulli.
- the insulation monitor can now easily determine whether such a ground fault exists or not.
- each tension member is electrically connected to one another at a first end of the suspension element.
- two tension members are electrically connected to the current or voltage source at a second end of the suspension element, two further tension members are electrically connected to the measuring device, and any further tension members are electrically connected to each other in pairs.
- a method for monitoring at least one support means in an elevator system wherein the support means comprises a plurality of parallel in a common plane juxtaposed electrically conductive tension members, which are electrically isolated from each other, and which are surrounded by a common jacket ,
- the method comprising the steps of: passing a test current through a first set of tension members; Passing the test current through the second group of tension members; and determining a characteristic of the test current by means of a measuring device, wherein the test current is passed through the measuring device after it is passed through the first group of tension members, and before it is passed through the second group of tension members.
- This method offers the advantage that different states of the suspension element can be determined in a simple manner. Thus it can be determined with a very high reliability whether one of the tension members is interrupted and whether there is an electrical contact between two adjacent tension members. In both cases, a current intensity or a voltage at the measuring device changes markedly. Thus, it is not necessary to determine exact values with the measuring device. This makes the process more robust against disturbing influences such as temperature fluctuations, electromagnetic radiation, movements of the suspension element and the like.
- the tension members of this first group when passing the test current through the first group of tension members, are each spaced apart by a tension member of the second group of tension members, and when passing the test flow through the second group of tension members, the tension members of this second group are respectively spaced apart by a tension member of the first group of tension members.
- the tension members of the first group of tension members and / or the tension members of the second group of tension members are connected in series during the conduction of the test current through the first and second groups of tension members.
- test current is passed through all the tensile carriers of the suspension element.
- an alternating current or a direct current or an electrical signal is conducted through the tension members during the conduction of the test current.
- a voltage or a current intensity or a signal property is determined.
- the method comprises the step: checking the circuit consisting of at least the first group of tension members and the second group of tension members for ground fault.
- a suspension in an elevator system can be used in different types of elevator systems.
- elevator systems with or without shaft, with or without counterweight, or even elevator systems with different gear ratios can be used.
- each suspension element in an elevator installation which comprises a plurality of electrically conductive tension members, which are surrounded by a common insulating jacket, can be monitored with the method disclosed here or with the device disclosed here.
- Figure 1 shows an exemplary embodiment of an elevator system
- Figure 2 shows an exemplary embodiment of a support means
- Figure 3 shows an exemplary embodiment of a support means with a monitoring device.
- the elevator installation 40 illustrated schematically and by way of example in FIG. 1 includes an elevator cage 41, a counterweight 42 and a suspension element 1 and a traction sheave 43 with associated drive motor 44.
- the traction sheave 43 drives the suspension element 1 and thus moves the elevator cage 41 and counterweight 42 counter to one another ,
- the drive motor 44 is controlled by an elevator control 45.
- the cabin 41 is designed to receive people or goods and to transport between floors of a building. Cabin 41 and counterweight 42 are guided along guides (not shown). In the example, the cabin 41 and the counterweight 42 are each suspended on support rollers 46.
- the suspension element 1 is fastened to a first suspension element fastening device 47, and then guided first around the support roller 46 of the counterweight 42.
- the suspension element 1 is placed over the traction sheave 43, guided around the carrier roller 46 of the cabin 41, and finally connected by a second suspension element fastening device 47 to a fixed point.
- the wrap factor is 2 to 1.
- a loose end 1.1 of the suspension element 1 is provided with a Needlesssensvomchtung 2 for temporary or permanent electrical contacting of the tension members and thus for monitoring the support means 1.
- such a contacting device 2 is arranged at both ends 1.1 of the suspension element 1.
- the Tragstoffenden 1.1 are no longer burdened by the tensile force in the suspension element 1, as this tensile force is already passed through the suspension means fastening devices 47 into the building.
- the contacting devices 2 are thus arranged in a non-overrun area of the suspension element 1 and outside the loaded area of the suspension element 1.
- the Kunststoff musclessvomchtung 2 is connected at one end of the support means 1.1 with a monitoring device 3.
- the monitoring device 3 comprises a current or a voltage source and a measuring device.
- the monitoring device 3 is also connected to the elevator control 45.
- This connection can be designed, for example, as a parallel relay or as a bus system.
- a signal or a measured value can be transmitted from the monitoring device 3 to the elevator control 45 in order to take into account the state of the suspension element 1 as determined by the monitoring device 3 in a control of the elevator 40.
- the elevator installation 40 shown in FIG. 1 is exemplary. Other capping factors and arrangements, such as counterbalanced lift systems, are possible.
- the Kunststofftechniksvomchtung 2 for contacting the support means 1 is then arranged according to the placement of the support means fixing devices 47.
- FIG. 2 shows a section of an exemplary embodiment of a suspension element 1.
- the support means 1 comprises a plurality of parallel electrically in a common plane juxtaposed electrically conductive tension members, which are surrounded by a common electrically insulating jacket.
- the jacket 6 can be pierced or removed, for example, or the tension members 5 can also be electrically contacted on the face side by a contacting device 2.
- contact elements can be attached to the tension members 5, which can then be connected in a simple manner with themaschineticiansvomchtung 2.
- the suspension element 1 is equipped with longitudinal ribs on a traction side.
- the suspension element 1 can also be designed differently, for example without longitudinal ribs, or with a different number or a different arrangement of the tension members 5. It is essential for the invention that the tension members 5 are designed to be electrically conductive ,
- FIG. 3 shows an exemplary embodiment of a suspension element 1 with contacting devices 2 and a monitoring device 3.
