Definitions

• the present invention relates to an elevator installation with a maintenance system and a method for maintenance of an elevator installation.
• hardware components for the definition of the maintenance intervals are divided into groups which either comprise hardware components with an approximately identical maintenance requirement or technically and / or spatially linked hardware components. For these different groups, different maintenance intervals are then stored as maintenance data in a memory area of the maintenance system on which can be accessed by an input or remote input device.
• the maintenance system can be part of the elevator control or a separate system, however, connected or connectable to the elevator control.
• the hardware components of the elevator combined in a maintenance group are to be called maintenance modules below.
• the elevator and customer-specific definition of these modules can take into account the wishes of the customer or the general conditions specified by the hardware component of the elevator system, so that optimized individual customer-specific and elevator-specific maintenance is possible with minimal maintenance.
• the modules are defined in such a way that hardware components with an approximately equal maintenance requirement are combined, maintenance-intensive and wear-prone hardware components of the elevator are subjected to maintenance more often than the hardware components in modules with a lower maintenance requirement.
• the hardware components of the elevator can of course also be selected in the maintenance modules according to other criteria.
• One criterion is e.g. B. a certain spatial link.
• Maintenance modules defined in this way can be used to achieve an organizationally streamlined maintenance service, which in turn leads to lower maintenance costs.
• a standard group of hardware components to be checked can be summarized in a basic module.
• Such a maintenance module could, for example, include all maintenance activities that can be recorded in a visual inspection of the elevator car, the elevator shaft, the control cabinet and the cables and pull cables.
• This basic module could also be used to check travel tolerances and to record the subjective condition of the elevator system.
• a basic module could z. B. can be stored as a basic maintenance module with a bimonthly interval in a memory area of the maintenance system. The hardware components and the associated maintenance work associated with the hardware components would then preferably be stored in this module together with the time for carrying out the maintenance work.
• a drive module d. H. a maintenance group which includes all lubrication, cleaning and testing work on hardware components of the drive, and furthermore a door module which comprises all hardware components and associated maintenance work related to the doors.
• a shaft module that contains all hardware components in the shaft, such as B. could include guide rails, ropes, switches, travel head guides, counterweight guides, safety gear, rope tensions and buffers, as well as the associated maintenance work, again lubrication, cleaning and testing.
• an electrical module would be conceivable that relates to the cleaning and testing of all the elevator's electrical units. While the basic module in the example above could be carried out at two-month intervals, the other maintenance modules, such as drive modules, door modules, shaft modules or electrical modules, would be carried out at larger intervals.
• the drive module can e.g. B. with every third basic module, the door module with every fourth basic module and the shaft module with every fifth basic module.
• the corresponding maintenance module After a maintenance module has been processed, the corresponding maintenance module is acknowledged or reset by an input device or by remote input. If this does not happen, there is Maintenance system after the predetermined maintenance time is exceeded, an alarm signal that can be routed, for example, via a long-distance line to a KONE maintenance center.
• the predetermined maintenance intervals are not rigid, but can be varied in an advantageous embodiment of the invention by sensors that check the state or the setting of different hardware components.
• several hardware components of the elevator can be equipped with sensors that provide information about the setting and / or wear of the hardware components to the control and / or the maintenance system. These signals can be used to push a maintenance interval of a group further forward or further back, depending on the individual state of the time-determining hardware component in the group or in the module.
• the date for the execution of a maintenance module can also be shifted by a "manual" entry if, for. B. an unscheduled maintenance service was carried out on certain hardware components.
• the maintenance system preferably merges the times of adjacent maintenance modules, so that no unnecessary travel costs arise with successive maintenance modules.
• the control and / or the maintenance system has a clock in order to carry out a time comparison between the current time and the time of a maintenance module to be carried out in connection with a comparator and to be able to generate an alarm signal when exceeded.
• a remote input device can also be used to coordinate the times for the maintenance modules with official inspection measures, for example the inspection work of a technical monitoring association.
• cleaning modules In addition to pure maintenance modules, in a very comfortable embodiment of the invention, hardware components in connection with the required cleaning work can also be combined in groups, so-called cleaning modules. These cleaning modules can be stored together with the maintenance modules with assigned times or time intervals in the storage unit of the maintenance system or the elevator control.

• These hardware components 14 of the elevator system have sensors that transmit signals about the state or the setting of the respective component to the central controller 12.
• the maintenance system further comprises two memory areas 16 and 18, with maintenance time data in association with groups (modules) of hardware components being recorded in the memory area 16, which groups, for example base module BM, door module TM and drive module AM, are precisely specified in memory area 18 (see also FIG . 2).
• three maintenance modules BM, TM and AM are stored with the associated maintenance time data assigned in the memory area 16.
• the maintenance work corresponding to the hardware components can also be stored in the memory area 18.
• the way in which the modules are combined in the storage areas 18 depends on individual customer requirements and the type of elevator installed.
• the time data 16 corresponding to the maintenance modules 18 can be changed via the sensor data by the hardware components 14 by means of the maintenance system in the elevator control system 12, but time data from different maintenance modules that are closely spaced in time are always replaced by an identical maintenance date in order to carry out maintenance work in a denser time Prevent sequence with the associated travel costs.
• the controller 12 and / or the maintenance system 13 also has an input device 22, a printer 24, a connection 26 for a remote data transmission network and a monitor 28.
• the maintenance system and the input and output devices 22, 24 and 28 can in principle also be in a maintenance center installed by the elevator operator, so that no input and output devices have to be provided on site.
• the input and Output device with the maintenance system may also be carried as a portable device by maintenance personnel.
• the central controller 12 or the maintenance system 13 After the customer and system-specific definition and input of the maintenance modules and the assigned maintenance time data in the memory areas 18 and 16, the central controller 12 or the maintenance system 13 checks the implementation of these maintenance modules by comparing them with the current system time, which is updated, for example, by a battery-backed radio clock can.
• This maintenance time data can be changed internally by signals from the hardware components 14.
• a message about the change in the maintenance data can, for example, be forwarded to a maintenance center via the remote transmission network 26, as can the entire module maintenance schedule, i. H. the content of the memory areas 16 and 18.
