  3 and 4 are side views showing a state in the hoistway when an elevator installation operation is performed using a conventional work floor device (including the one described in Patent Document 1).

  3 and 4, 16 is a weight rail for guiding the lifting and lowering of the counterweight 17 (not shown in FIGS. 3 and 4). FIG. 3 shows a state in which the worker rides on the cab working floor 19 and performs the centering work of the weight rail 16 at a position (height) slightly away from the bottom surface of the hoistway 7. If the position (height) is some distance away from the bottom surface of the hoistway 7, the centering operation of the weight rail 16 can be performed without any problem even if a conventional work floor device is used.

  However, when the centering work of the weight rail 16 installed at the lowermost part of the hoistway 7 is performed, for example, when the first and second stage weight rails 16 are centered from the bottom, in the conventional work floor device, the car Since the position of the floor surface of the room work floor 19 is too high (the position where the centering operation is performed is too low), the operation cannot be performed. Moreover, even if an operator descends to the bottom surface of the hoistway 7, the work position is too high and the centering work of the weight rail 16 cannot be performed. For this reason, conventionally, a temporary scaffold 20 is assembled from the bottom surface of the hoistway 7, and the worker rides on the scaffold 20 and performs centering of the first and second stages (see FIG. 4). However, such a method has a problem that it takes time to assemble and disassemble the temporary scaffolding 20 and the working efficiency is greatly reduced. Further, a place for temporarily storing the scaffold 20 (various members constituting the scaffold 20) is also required.

  Further, in some installation methods, the weight rail 16 is centered after the elevator counterweight 17 and the work floor device are suspended in a fishing bottle type in the hoistway 7. In such a case, there is a problem that the counterweight 17 and the operator overlap in the vicinity of the intermediate portion of the hoistway 7 and the rail bracket 18 for fixing the weight rail 16 cannot be disposed at an appropriate position.

  FIG. 5 is a side view showing a state in the hoistway when an elevator installation work is performed using a conventional work floor device. The counterweight 17 is the same height as the worker on the cab room work floor 19. This shows the state of being arranged. In the state shown in FIG. 5, the counterweight 17 is in the way, and the operator cannot determine the position of the weight rail 16 and fix the rail bracket 18 at that position (height). For this reason, the worker raises or lowers the cab working floor 19 from the state shown in FIG. 5 to shift the position of the counterweight 17 and installs the rail bracket 18 at a position where it does not overlap with the counterweight 17. In such a case, the installation accuracy of the weight rail 16 may be deteriorated.

The present invention has been made to solve the above-described problems, and an object thereof is to provide an elevator work floor device capable of greatly improving the work efficiency when the elevator is installed. It is to be.
Another object of the present invention is to provide an elevator work floor device that can accurately install the weight rail even when the weight rail is centered after the counterweight is suspended in the hoistway. Is to provide.
