Description

  The present invention relates to an elevator lifting / lowering device for lifting / lowering an elevator on which an automobile stored by an elevator parking device is placed between a floor of an entrance / exit and a floor of a parking room.

The elevator type parking device has an elevator for placing a car and raising and lowering it in the central part of the parking building between the entrance / exit and a plurality of parking room floors stacked for storing the car. I have. There is one using a plurality of wire ropes as one of means for raising and lowering the elevator. The space occupied by the lifting device deployed in the machine room on the top floor for raising and lowering the elevator by wire rope is also the size of the space to secure the parking room or reduce the scale of the entire parking building as much as possible. It is desirable to make it as small as possible.

  Furthermore, one end of the wire rope is locked to the elevator side, and the other end is locked to the counterweight side. The intermediate portion is wound around a drive sheave for driving the elevator up and down, and the elevator And a plurality of baffle sheaves that are rotatable in the vertical and horizontal directions to guide the wire rope to the counterweight and the drive sheave.

However, as the number of deflecting sheaves for guiding the wire rope increases, bending fatigue increases due to an increase in the number of times the wire rope moves up and down the elevator with the drive sheave. Increase to shorten the life of wire rope. In addition, since the magnitude of the bending stress changes due to the diameter of the deflecting sheave, it is desirable that the diameter of the deflecting sheave is large.
