Definitions

  • the invention relates to a device for the protection of in an elevator shaft maintenance operations exporting Maintenance personnel, with the maintenance of the roof of a executed elevator car in the elevator shaft and the maintenance staff in the process of Elevator cabin hazards arising from shaft equipment is exposed, with the trained as a protective shield Protective device in case of accident the elevator car shuts down.
  • a disadvantage of the known device is that the accessibility of the cabin roof at each shaft height is limited, although a restriction only in the top Floor area is necessary.
  • WO 01/58796 is a safety device become known, which consists essentially of a at the Manhole cover suspended detection plate consists of the underside of which an airbag is arranged.
  • the disadvantage of this device is the expensive Suspension of the detection plate on the shaft ceiling.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the task to avoid the disadvantages of the known device and a protective device for in a hoistway To provide maintenance work to maintenance executives which is limited to the danger spot.
  • the advantages achieved by the invention are in essential to see that the accessibility of the Cabin roof only in the area of the danger point is restricted. In the other cabin positions is the canopy, however, fully accessible and for Maintenance work available. This will be the from the Cab roof made maintenance work easier and can be done more efficiently. Maintenance work for example, over the entire shaft height extending guide rails can only be executed when the entire cabin roof is accessible. The same applies for shaft-side maintenance work on landing doors. in the the rest is the entire roof surface of the canopy for the installation of an emergency exit available.
  • Fig. 1 shows a schematic representation of a in a Shaft head 1 of a hoistway 2 arranged stationary shaft equipment 3 with a protective shield 4.
  • One by means of support frame 5 and a lower not shown yoke and an upper yoke 6 worn Elevator car 7 is demarcated 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, wherein the elevator car 7th for example, with a not shown, by means of Drive unit 3 driven suspension cable with a not connected counterweight is connected.
  • the upper yoke 6 and / or the roof 8 of the elevator car 7 are of Maintenance personnel 9 walkable.
  • the vertical projection of the Drive unit 3 projects beyond the vertical projection of Elevator car 7, the support frame 5 and the upper yoke. 6
  • the shield 4 prevents the maintenance personnel 9 between drive unit 3 and elevator car 7 or Support frame 5 or upper yoke 6 may be advised. at Operation of the shield 4, the elevator car 7th stopped.
  • Fig. 2 shows a spatial representation of the shaft head 1 with the top floor elevator car 7, wherein the elevator car 7 via a landing door 10th is reachable.
  • rollers 11 lead 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 not shown counterweight.
  • a Traction sheave 14 of the drive unit 3 does not drive this shown supporting rope.
  • the drive unit 3 is from a console 15 carried on the guide rails 12,13 is supported.
  • the shield 4 is on the console 15 pivotally mounted and shown in the normal position. A small pivoting movement of the shield 4 upwards sets the elevator car 7 still. So that the drive unit 3 is accessible at the bottom, the shield is 4 swivels downwards by about 90 °.
  • the Shaft head 1 also as stationary shaft equipment existing speed limiter 16 arranged.
  • Fig. 3 shows a plan view
  • Fig. 4 is a side view of the shield, which consists essentially of a on the Console 15 arranged housing 17 and a hood 18th consists.
  • a first Limit switch 19 for monitoring the release position of the hood 18th
  • a second limit switch 20 for monitoring the Open position of the hood 18.
  • One arranged on the hood 18 Flag 21 actuates the first limit switch 19.
  • the second Limit switch 20 is arranged by a on the hood 18 Flag 22 pressed.
  • the final position of the hood 18 is by means of a arranged on the housing 17, adjustable stop 23 determines the path of a return 24 of the hood 18th limited.
  • the end position of the hood 18 is shown 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 of Elevator system interrupts and thus the elevator car. 7 shuts down.
  • the normal position is shown in Fig. 4 with NL and the Open position is indicated in Fig. 4 with OL.
  • the Swing 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 labeled SW3.
  • FIGS. 5 and 5a show a spatial representation of the Shield 4 in open position.
  • a retaining spring 26 occurs in the return 24 in the return 24 in the return 24 .
  • the Z-shaped Retaining spring 26 holds the hood 18 in the normal position NL and allows a hood movement to the end position EL.
  • the with the opening 25 latching end of the retaining spring 26th can be released under force from the detent position be, with the hood 18 down to the open position is pivotable.
  • the hood 18 points in Guide rail area a recess 18.1, which the Pivoting the hood 18 allows.
  • FIG. 6 shows details of the shield 4 in Hinge area.
  • a designated 27 hinge allows the pivoting movement of the hood 18.
  • the hinge 27 connects the hood 18 pivotally connected to the housing 17, which is arranged by means of screws 28 on the console 15.
  • 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 shield 4 can also be used for other manhole equipment be used as the drive unit 3.
  • the elevator motor with electrical energy supplying frequency converters or pulleys or Suspensions or other not the elevator car Superior parts are provided with a protective shield.
