A roller 40 is provided on the outer side surface so as to be rotatable in contact with both side surfaces at the base of the blade portion 2a, and the guide 35 is smoothly moved along the guide rail 2 by the contact between the shoe 38 and the rollers 39, 40 and the blade portion 2a. To move to. A connecting plate 41 is rotatably attached to the outer surface of the case 36 via a pin 42. The guide 35 is fitted from the top of the guide rail 2 to the blade 2a before the pulley device 7 is attached to the guide rail 2.

  In the case of this embodiment, the lifting rope 16 of the lifting machine 14 is fed out and the shackle 17 at the tip thereof is lowered to a predetermined level, and a rope hitch 18 as an elevator article is used by using the hook 19 on the shackle 17. Are connected to a part of the rope hitch 18 via a pin 43 so as to be rotatable. The connecting plate 41 is preferably defined at a position below the connecting portion by the hook 19 and sufficiently away from the connecting portion.

  In this state, the lifting machine 14 is driven to retract the lifting rope 16 and the rope hitch 18 is pulled up. When the rope hitch 18 is lifted by driving the lifting machine 14, the guide 35 is lifted along the guide rail 2 integrally with the rope hitch 18. Then, the lateral movement of the rope hitch 18 is restricted by the guide 35, and therefore the rope hitch 18 is lifted up to the vicinity of the top of the hoistway 1 stably and safely by suppressing the swinging of the rope hitch 18 while it is rising. can do.

  FIG. 7 shows a fourth embodiment. In this embodiment, the pulley device 7 is installed on the top of the guide rail 2 via the jack bolt device 23 as in the case of the second embodiment. The pulley device 7 of this embodiment has a structure in which only one pulley 11a is provided at the end on one end side and only the shaft member 9 is provided on the end on the other end side.

  Then, a lifting rope 16 of the lifting machine 14 is wound around the pulley 11a, and a tip end portion of the lifting rope 16 is locked to the shaft member 9, and the pulley 11a and the shaft member 9 of the lifting rope 16 are engaged. Is suspended in a U shape, and a moving pulley device 45 is provided in the U shape. The moving pulley device 45 is configured by rotatably attaching pulleys 47 a and 47 b to both ends of a horizontally long plate material 46. The U-shaped lifting rope 16 passes under the pulleys 47 a and 47 b of the moving pulley device 45, and the moving pulley device 45 is horizontally supported by the lifting rope 16. A storage box 49 is suspended through a hanging tool 48.

  In the case of this embodiment, the lifting machine 14 is driven, the lifting rope 16 is fed out, the moving pulley device 45 is pulled down to a predetermined level position, and a relatively small elevator article is placed in the storage box 49 at that position. 50 is stored. Then, the lifting machine 14 is driven and the lifting rope 16 is retracted. By this pulling-in, the movable pulley device 45 rises together with the storage box 49 while maintaining a horizontal state, and the elevator article 50 in the storage box 49 is lifted up to the top of the hoistway 1. Therefore, the elevator article 50 can be taken out from the storage box 49 and installed at a predetermined installation position near the top of the hoistway 1.

  FIG. 8 shows a fifth embodiment. In this embodiment, a pulley device is provided at the top of each of a pair of adjacent guide rails, for example, a guide rail 52a for a car and a guide rail 52b for a counterweight. 7 is installed. The lifting machine 14 is connected to a bracket 53 that supports one guide rail 52a, and the lifting rope 16 of the lifting machine 14 is passed through the pulleys 11a and 11b of the pulley device 7 installed on the one guide rail 52a. Further, it is passed through the pulleys 11a and 11b of the pulley device 7 installed on the other guide rail 52b, and the end on the tip side is locked to the bracket 54 that supports the other guide rail 52b.

  A lifting rope 16 in a section extending between one pulley device 7 and the other pulley device 7 is suspended in a U shape, and for example, a beam 60 as an elevator article is supported on the U shape. A pulley 60 is rotatably attached to both ends of the beam 60 as an elevator article, and the U-shaped lifting rope 16 is hung on the pulley 62 to support the beam 60. .

  When the beam 60 as an elevator article is lifted and installed on the top of the hoistway 1, the beam 60 is attached to the lifting rope 16 via the pulley 62 as described above, and the lifting machine 14 is driven in this state. The lifting rope 16 is retracted and the beam 60 is raised. When the beam 60 reaches a position at a predetermined level, the lifting machine 14 is stopped, the beam 60 is installed at a predetermined installation position, and the lifting rope 16 is removed from the pulley 62 of the beam 60.

  Also in this case, since the pulley device 7 is attached to the tops of the guide rails 52a and 52b, the beam 60 is lifted up to a position at a close distance of the ceiling surface 1a of the hoistway 1 and installed at a predetermined installation position. be able to.

  As a means for installing the pulley device on the top of the guide rail, in addition to using a rail clip, an insertion hole is previously formed in the guide rail, a bolt as a fastener is passed through the insertion hole, and the bolt is It is also possible to fasten and fix the pulley device to the guide rail.

  Further, the pulley apparatus can be provided not only on the top of the guide rail, but also on the inner wall surface of the hoistway, for example, so that the pulley apparatus can be used for lifting and attaching a hold-a product.
