Definitions

  • the invention relates to a method for the maintenance of a Elevator, the elevator moving up from a pit up to a shaft head extending elevator shaft has, in which an elevator car is guided, and wherein several stops with shaft doors are provided.
  • EP-A-1 110 900 is a shaft safety system for the maintenance of an elevator that the Safety of a person during maintenance work in to ensure an elevator shaft.
  • the shaft safety system has a facility that automatically is activated when a shaft door is opened manually or is released for opening.
  • the facility is with a Control system for the cabin connected by the Activation is switched to a security mode that causes the cabin not to exceed a predetermined Position in the direction of the maintenance environment.
  • opening the bottom shaft door for maintenance of the the elevator pit arranged with the Activation of the device also includes a limit switch switched on, which prevents the cabin from under one certain level by that for an engine room required safety level is given, can drive. If the lower part of the cabin can be inspected or serviced , this can be done using the limit switch given level can be further reduced.
  • the shaft safety system described above is for Elevators designed without a machine room, but only the elevator drive arranged in the shaft pit and if necessary, a lower part of the cabin can be serviced can.
  • the object of the invention is therefore a method propose with which the entire elevator system is checked and can be serviced.
  • 1 denotes an elevator shaft, which extends from a shaft pit 2 to a shaft head 3 extends, and in which one of an elevator drive 4th driven elevator car 5 is guided.
  • the elevator points For example, four stops E1 to E4 and owns for example, no machine room, the elevator drive 4 and possibly associated control devices are housed in the shaft head 3.
  • shaft doors T1 to T4 are provided.
  • a maintenance person is referred to the Purpose of performing maintenance work on the cabin roof 7, or in the pit 2 (the dashed Representation of the maintenance person 6 should access them symbolize the shaft door T4 to the canopy 7).
  • a first and a second stop buffer (travel limiter) 8, 9 provided in a first and fourth maintenance position W1 or W4 into a movement of the elevator car 5 in the direction of shaft head 3 or shaft pit 2 Limiting position can be brought.
  • the displacement of the stop buffers 8, 9 into their limit position, as well as their return to the normal position is preferably carried out by means of an electrically controllable Actuator.
  • the corresponding control commands are through the elevator control depending on the current Maintenance operation situation generated.
  • the Position of the stop buffers 8, 9 is set by a switch monitors, and the release to move the elevator car to the next maintenance item is from Signals of these switches dependent. This position monitoring also allows a more economical version, in which the movement of the bump stops the maintenance person with the help of an outside of the Mechanism to be operated in the elevator shaft.
  • the maintenance items W1-W3 are selected so that the Maintenance person 6 easily climb or climb the canopy 7 can leave
  • 3 and 4 has two stops E11, E12 and, according to the example, also does not have one Machine room, with an elevator drive 14 and possibly associated control devices in a shaft head 13 of an elevator shaft 11 are accommodated.
  • On Canopy 17 of an elevator car 15 or a shaft pit 12 can be found at the stops E11, E12 Landing doors T11, T12 can be entered.
  • In elevator shaft 11 are for the same purpose as in Fig. 1 and 2 stop buffers 8, 9 provided in a first and third Maintenance position W11 or W13 in a limit position can be brought.
  • the elevator car 5, 15 in the maintenance operating mode moves automatically to a number of maintenance positions in a manner which is not described in any more detail, the maintenance being stopped while at the maintenance positions Canopy 7, 17 is carried out.
  • the maintenance person 6 remains on the cabin roof while traveling from maintenance position to maintenance position, the maintenance person 6 issuing the command to continue to the next maintenance position by means of a pushbutton (signal transmitter) 19 provided on the cabin roof.
  • the maintenance person When servicing the elevator according to the second method variant the same maintenance work is carried out as in the first method variant described above. In this case, however, the maintenance person leaves 6 after completion of the assigned to a maintenance item Maintenance work every time the canopy 7, after which the Elevator car automatically the next maintenance position starts up.
  • the maintenance person 6 goes, for example via a building staircase to which the current maintenance position corresponding shaft access where they canopy enters again.
  • the procedure concerning the fourth and last maintenance position, the pit maintenance position W4 corresponds to this second method variant essentially that of the first method variant, however, the maintenance person 6 goes after leaving the Canopy 7 in the third maintenance position W3 by the Landing door T2 via landing door T1 to shaft pit 2, while the elevator car 5 automatically to the pit maintenance position W4 is controlled.
  • Maintenance positions can be recognized by the elevator control system, for example, with the aid of a system with actuating skids 21 which can be freely displaced vertically in the shaft and a position signal transmitter (switch) 22 attached to the elevator car.
  • 5 shows such a system.
  • a system with position signal transmitters 23 slidably arranged in the shaft and an actuating skid 24 attached to the elevator car, as shown in FIG. 6, can also be implemented.
  • the double arrows in FIGS. 5 and 6 indicate the vertical adjustability of the actuating skids 21 or the position signal transmitter 23 for determining associated maintenance positions.
  • Maintenance positions are preferred, especially at Elevators with continuous detection of the car position, freely programmable.
  • the freely programmable entry of Maintenance positions can take place, for example, by that a maintenance item by the maintenance person with Help - usually on the roof of the elevator car 5 arranged - inspection control is started, whereupon with one only when the inspection control is switched on effective hand-operated signal generator 20, the elevator control is caused, the current position of the elevator car to register as a new maintenance item. With the same or another signal generator can automatically Approached maintenance position from the elevator control memory to be deleted.
  • Maintenance positions can also be fixed directly on the Elevator control available or connectable to it Input terminal can be programmed or deleted.
