A car position adjustment drive device 11 is placed, and the car position adjustment drive device 11 is provided with a car position adjustment drive sheave 11a. The car position adjusting rope 12 which is a cord-like body is wound around two upper car pulleys 9a and 9b which are fixed to the upper beam 2a via the elastic body 13 and attached to the lower part of the upper car 9. The upper car 9 is suspended and is wound around the car position adjustment drive sheave 11 a of the car position adjustment drive device 11. Thereafter, the car position adjusting rope 12 is wound around two lower car pulleys 10a and 10b attached to the lower part of the lower car 10 to suspend the lower car 10, and the other end is attached to the intermediate beam 2d via the elastic body 14. Fixed.

  The double deck elevator constructed in this manner is such that the car position adjustment drive device 11 is driven by the control device 8 to rotate the car position adjustment drive sheave 11a, and the car is adjusted by the rotation of the car position adjustment drive sheave 11a. Within the frame 2, the upper car 9 and the lower car 10 are driven upside down. As shown in FIG. 1, when the car frame 2 is on the upper floor, the distance between the landing floors is H1, and accordingly, the distance between the upper car 9 and the lower car 10 is adjusted to the dimension H1, In the case of the lower floor, the interval between the landing floors changes to H2, and accordingly, the interval between the upper car 9 and the lower car 10 can be changed to H2.

  As shown in FIG. 2, the inspection device 15 according to the first embodiment includes a beam member 15a fixed to a predetermined height position of the guide rail G, and supported by the beam member 15a. A scaffold plate 15b that can be opposed to the upper beam 2a and a handrail member 15c provided on the scaffold plate 15b are provided. Further, two inspection devices 15 are provided so as to sandwich the car frame 2 and are arranged on each of the paired guide rails G, and the beam member 15a and the scaffolding plate 15b of each inspection device 15 are guides. The rail G is disposed on the side opposite to the cage frame.

  As shown in FIGS. 3 and 4, the scaffold plate 15b is folded and stored in a position where it does not interfere with the car frame 2 when not in use, and is pulled out and bridged between the upper beam 2a at the time of inspection. A movable transition plate 15d is provided. Further, the crossover plate 15d is provided with a movable handrail member 15e that is folded when not in use and pulled out in conjunction with the use of the crossover plate 15d.

  In the first embodiment, when inspecting the car equipment installed in the car frame 2, for example, two workers get on the car frame 2, move the car frame 2 in the maintenance mode, and move downward. The scaffold plate 15b of the inspection device 15 that is positioned and the upper beam 2a of the car frame 2 are set as opposing positions. In this state, as shown in FIGS. 3 and 6, the movable bridge plate 15d is pulled out and bridged between the scaffold plate 15b and the upper beam 2a, and at least one operator is located below the inspection device 15. Change to. At this time, as shown in FIG. 5, the movable portion 15c1 of the handrail member 15c is flipped up to allow the passage plate 15d to pass, and in conjunction with the use of the passage plate 15d, as shown in FIG. The member 15e is pulled out, and safety is ensured when the worker passes the crossing plate 15d. From the inspection device 15 located below, the worker inspects, for example, the car position adjustment rope 12 that is hung around to drive the upper car 9 and the lower car 10. After the worker returns to the car frame 2, the car frame 2 is further raised, and the scaffold plate 15 b of the inspection device 15 located above and the upper beam 2 a of the car frame 2 are set to be opposed positions. In this state, the movable bridge plate 15d is pulled out, bridged between the scaffold plate 15b and the upper beam 2a, and one worker moves to the inspection device 15 located above. From this state, the car frame 2 is further raised by another worker, the inspection device 15 positioned above and the car position adjustment drive device 11 installed above the car frame 2 are opposed to each other, and the inspection device positioned above. From 15, the worker inspects the car position adjustment drive device 11. In this manner, the car equipment installed in the car frame 2 is inspected sequentially while moving the car frame 2 and using the inspection device 15.

  According to the first embodiment, the inspection of the car equipment of the double deck elevator is performed using the dedicated inspection table 15 provided in the hoistway 1, whereby the work can be performed safely and efficiently. In particular, since the beam member 15a is fixed to the guide rail G standing on the hoistway 1, it is easy to install the inspection device 15 at a desired height position, and the working range in the vertical direction is small. Appropriately respond to inspection work on large double deck elevators.

  Further, the guide rail G to which the beam member 15a is fixed is provided in advance in the double deck elevator and has a strength to support the inspection device 15, thereby adding a special support member. Thus, the inspection device can be provided without any problems, and therefore the cost can be reduced. Further, the scaffold plate 15b is provided with a movable bridge plate 15d that is folded when not in use and stored in a position where it does not interfere with the car frame 2, and is pulled out and bridged between the upper beam 2a at the time of inspection. Therefore, it is possible to easily go back and forth between the inspection device 15 and the car frame 2.

  Furthermore, since the beam member 15a and the scaffolding plate 15b are disposed on the side opposite to the cage frame of the guide rail G, the inspection device 15 can be disposed without hindering the raising and lowering of the cage frame 2. In addition, a movable handrail member 15e is provided on the transition plate 15d, so that the worker can safely go back and forth between the inspection device 15 and the car frame 2. Further, since the beam member 15a is attached to the guide rail G via the rail clip 15f, the beam member 15a is detachable. Therefore, the inspection device 15 can be attached or detached as necessary, or the height position thereof can be adjusted. Change is relatively easy.
