Definitions

  • the invention relates to a device for protecting in an elevator shaft performing maintenance work Maintenance personnel, the maintenance work from the roof of a Executable elevator car in the elevator shaft and the maintenance staff when moving the Dangers posed on train cabins by shaft equipment is exposed.
  • a disadvantage of the known device is that the accessibility of the cabin roof at every shaft height is restricted, although a restriction is only on the top Floor area is necessary.
  • the invention seeks to remedy this.
  • the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and a protective device for in an elevator shaft To create maintenance personnel performing maintenance work, which is limited to the danger point.
  • the advantages achieved by the invention are in essential to see that the accessibility of the Cab roof only in the area of the danger point is restricted.
  • the cabin roof is fully accessible and for Maintenance work can be used.
  • Maintenance work for example, over the entire shaft height extending guide rails can only be carried out when the entire cabin roof is accessible.
  • shaft-side maintenance work on storey doors in the the rest of the roof area of the cabin roof stands for the installation of an emergency exit is available.
  • Fig. 1 shows a schematic representation of one in one Well head 1 of an elevator shaft 2 arranged stationary shaft equipment 3 with a protective shield 4.
  • One using a support frame 5 and a lower one is not shown yoke and an upper yoke 6 worn Elevator car 7 is delimited by means of reinforcement 2.1 Elevator shaft 2 movable.
  • the as stationary Shaft equipment 3 named drive unit 3 drives the Elevator car 7, the elevator car 7 for example with a not shown, by means of Drive unit 3 driven suspension cable with a not represented counterweight is connected.
  • the upper yoke 6 and / or the roof 8 of the elevator car 7 are from Maintenance personnel 9 accessible.
  • the vertical projection of the Drive unit 3 projects beyond the vertical projection of the Elevator car 7, the support frame 5 and the upper yoke 6.
  • the protective shield 4 prevents the maintenance personnel 9 between drive unit 3 and elevator car 7 or Support frame 5 or upper yoke 6 can get. at Actuation of the protective shield 4 becomes the elevator car 7 stopped.
  • Fig. 2 shows a spatial representation of the shaft head 1 the elevator car 7 standing on the top floor, wherein the elevator car 7 via a floor door 10 is achievable.
  • Guide rollers 11 arranged on the support frame the support frame 5 and thus the elevator car 7 along extending over the elevator shaft 2 Guide rails 12. With 13 are the guide rails of the called counterweight not shown.
  • a Traction sheave 14 of drive unit 3 does not drive this shown carrying rope.
  • the drive unit 3 is from a bracket 15 worn on the guide rails 12,13 is supported.
  • the protective shield 4 is on the console 15 pivotally arranged and shown in the normal position. A small swiveling movement of the protective shield 4 upwards stops the elevator car 7. So that the drive unit 3 is accessible at the bottom, the protective shield 4 can be swiveled downwards by about 90 °.
  • Shaft head 1 also as stationary shaft equipment applicable speed limiter 16 arranged.
  • FIG. 3 shows a top view and FIG. 4 shows a side view of the protective shield, which essentially consists of one on the Console 15 arranged housing 17 and a hood 18th consists.
  • a first is arranged on the housing 17 Limit switch 19 for monitoring the release position of the hood 18 and a second limit switch 20 for monitoring the Open position of the hood 18.
  • An arranged on the hood 18 Flag 21 actuates the first limit switch 19.
  • the second Limit switch 20 is arranged by one on the hood 18 Flag 22 operated.
  • the end position of the hood 18 is determined by an adjustable stop arranged on the housing 17 23 determines the path of a return 24 of the hood 18th limited.
  • the end position of the hood 18 is in Fig. 4 with EL designated.
  • the release position at which the first limit switch 19 is actuated is designated in Fig. 4 with AL, wherein the first limit switch 19 the safety circuit
  • the elevator system interrupts and thus the elevator car 7 shuts down.
  • the normal position is in Fig. 4 with NL
  • Open position is designated in Fig. 4 with OL.
  • the Swivel angle between the end position EL and the release position AL is with SW1
  • the swivel angle between the release position AL and the normal position NL is with SW2
  • the swivel angle between the normal position NL and the open position OL of the hood 18 is designated SW3.
  • FIG. 5 and 5a show a spatial representation of the Protective shield 4 in the open position.
  • the return 24 is one Opening 25 arranged through which when closing the hood 18 a retaining spring 26 occurs.
  • the Z-shaped Retaining spring 26 holds the hood 18 in the normal position NL and enables a hood movement up to the EL end position.
  • the end of the retaining spring 26 latching with the opening 25 can be released from the detent position under force be, with the hood 18 down to the open position is pivotable.
  • the hood 18 has in Guide rail area a recess 18.1 that the Pivoting the hood 18 allows.
  • FIG. 6 shows details of the protective shield 4 in Hinge area.
  • a hinge labeled 27 enables the swiveling movement of the hood 18.
  • the hinge 27 pivotally connects the hood 18 to the housing 17, which is arranged on the bracket 15 by means of screws 28.
  • the hinge 27 is at one end by means of screws 29 with the Housing 17 and the other end by means of screws 30 with the Hood 18 connected.
  • the protective shield 4 can also be used for other shaft equipment can be used as the drive unit 3.
  • the elevator motor with electrical energy supplying frequency converter or deflection rollers or Suspensions or other not the elevator car protruding parts are provided with a protective shield.
  • several shaft equipment parts with one Protective hood.
