Definitions

  • the invention relates to an elevator installation with a lubricating device for a suspension element, and a method for lubricating a suspension element in an elevator installation.
  • Suspension elements in elevator installations are usually relubricated manually by service personnel.
  • the support means is handled by hand with lubricant with a rag or the like.
  • the quality of such relubrication depends on the reliability and individual skills of the service person.
  • an application of such a lubricating device as a device permanently installed in the elevator installation has the disadvantage that the amount of lubricant can not or can not be controlled sufficiently well.
  • too much lubricant on the support means can lead to traction losses on the traction sheave or even soiled brake shoes of the braking device, which can affect both a safety of the elevator system.
  • An object of the present invention is to provide an elevator system with a suspension means which is lubricated in a reliable and cost-effective manner.
  • an elevator installation with a cabin and with a suspension element wherein the cabin is at least partially supported by the suspension element.
  • a lubricating device is arranged at the suspension means, wherein an activity of the lubricating device is dependent on at least one operating parameter of the elevator installation.
  • Such an arrangement initially has the advantage that the lubricating device is permanently arranged in the elevator installation, so that a service effort by the service personnel is reduced.
  • the lubrication of the suspension means is not dependent on the reliability of the service personnel to the same extent.
  • Another advantage of such an arrangement is that an optimal amount of lubricant can be used by the dependence of the lubrication of the support means of a use parameter of the elevator system. This prevents excessive lubrication as well as too little lubrication, which has a positive effect on the service life of the suspension element. It also prevents traction losses on the traction sheave or brake force losses due to contamination of the brake system due to excessive lubrication.
  • the lubricating device is arranged in the vicinity of a traction sheave or in the vicinity of a deflection roller in the suspension element.
  • a plurality of lubricating devices are arranged in the elevator installation such that the largest possible area of an entire length of the suspension element can be detected by the lubricating devices.
  • a lubricating device may be disposed near the counterweight diverting pulley, and a lubricating device may be disposed near a cabin diverting pulley.
  • the lubricating device is arranged decoupled relative to the support means.
  • the lubricating device is only in the activity of Lubricating device coupled to the support means.
  • Such a coupled arrangement of the lubricating device has the advantage that an unscheduled lubrication of the suspension element can be prevented, and that at the same time abrasion problems of the suspension element can be prevented by the lubricating device.
  • the lubricating device is coupled to the support means only when the lubricating device is active, it is possible to ensure that quantities of lubricant which are not unforeseen arrive outside the activity times of the lubricating device against the suspension element.
  • the lubricating device comprises an annular nozzle.
  • the activity of the lubricating device is dependent on at least one operating parameter of the elevator installation.
  • a usage parameter of the elevator installation is selected, which is related to wear of the suspension element. This ensures that the suspension element is relubricated according to the prevailing wear conditions.
  • a number of trips of the car is used as the usage parameter. It can be used as a parameter, for example, an absolute number of trips, or even a number of trips in a time interval.
  • This has the advantage that frequently used elevator systems are relubricated more frequently than infrequently used elevator systems. As a result, the use of the elevator system corresponding lubrication of the support means can be ensured. Since a number of trips are already detected by control of the elevator for other purposes, no additional effort needs to be made to determine this usage parameter.
  • a range of trips of the car in the elevator installation is used as the usage parameter.
  • a drive of the cabin over an entire height of the elevator installation can have a different effect on the activity of the lubricating device than a drive of the cabin over only one floor.
  • a usage parameter is used, which is already detected by a control of the elevator for other purposes. Thus, no time-consuming and expensive new detection devices must be installed.
  • a slip of the suspension element on the traction sheave is used as the use parameter.
  • This usage parameter also relates to a detection device which is usually already present in elevator systems. This results in no additional costs in the detection of this use parameter.
  • a temperature measured in the elevator installation is used as the use parameter.
  • the use parameters mentioned here by way of example can be used both individually and in combination with one another.
  • a number of trips may be used as a trigger of the activity of the lubricator, and a certain amount of slip of the suspension on the traction sheave may be used as a signal to inactivate the lubricator.
  • several usage parameters can be offset against each other in order to achieve a more precise lubrication of the suspension element.
  • areas and numbers of trips can be combined with one another in order to be able to sufficiently lubricate particularly stressed suspension element areas. It goes without saying that a variety of other usage parameters in the context of this invention can be used for the control of the lubricating device.
  • a method for lubricating a suspension in an elevator system comprising a car and a support means, wherein the car is at least partially supported by the support means.
  • the method comprises the steps of: detecting at least one usage parameter of the elevator installation; and activating a lubrication device arranged on the suspension element as a function of the detected usage parameter.
  • the lubricating device is coupled with the activation of the support means.
  • the method further comprises the step of decoupling the lubricating device with the suspension element as a function of the detected usage parameter.
  • the coupling or decoupling of the lubricating device with the support means is controlled by a signal control.
  • This has the advantage that the lubricating device is coupled to the support means, for example, only when a corresponding control signal originates from an elevator control to the lubricating device.
  • a lubricant quantity and / or a lubrication interval duration of the detected use parameter are adjusted. This has the advantage that lubrication of the suspension can be done very targeted.
  • lubricating devices with a constant amount of lubricant can be used as well as lubricating devices with a variable amount of lubricant flowing out.
  • a lubricant composition when activating the lubricating device, is adapted to the detected usage parameter.
  • the suspension element can be relubricated with different lubricants depending on the situation. For example, at a low temperature, a different lubricant may be used than at a high temperature in the elevator installation.
  • FIG. 1 schematically illustrated lift system 40 includes an elevator car 41, a counterweight 42 and a support means 1 and a traction sheave 43 with associated drive motor 44.
  • the traction sheave 43 drives the support means 1 and thus moves the elevator car 41 and the counterweight 42 gegentechnisch.
  • the drive motor 44 is controlled by an elevator control 45.
  • the cabin 41 is designed to accommodate persons and 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 car 41 and the counterweight 42 are each suspended from pulleys 46.
  • the support means 1 is fastened to a first support means fastening device 47, and then first guided around the deflection roller 46 of the counterweight 42.
  • the suspension element 1 is placed over the traction sheave 43, guided around the deflection roller 46 of the cabin 41 and finally connected by a second suspension means fastening device 47 with a fixed point.
  • the wrap factor is 2: 1.
  • a lubricating device 6 is arranged at the suspension element 1.
  • the lubricating device 6 is also connected to the elevator control 45.
  • an activity of the lubricating device 6 in dependence on use parameters, which are processed by the elevator control 45, take place. For example, a number of trips of the car 41 can be used as the usage parameter.
  • the suspension element 1 is relubricated after a thousand journeys of the cabin 41 in a lubricating operation, in which the cabin 41 is moved over a total passable height of the elevator installation 40.
  • the elevator installation 40 shown in FIG. 1 is exemplary. Other capping factors and arrangements, such as counterbalanced lift systems, are also possible. In addition, other arrangements of the lubricating device 6 in the elevator system are possible.
