Abstract

The invention provides a drive device for a double deck elevator, capable of reducing the elongation of a rope in a simple configuration without requiring a special device. In the double deck elevator having an upper car 2 and a lower car 3 which are vertically movable in a car frame 1 in the counter directions, the rope-like body 44 of a drive means 41 for driving the upper car 2 and the lower car 3 has a wire rope 44a within a range which is brought into contact with a sheave 41a and pulleys 42, 43 and an auxiliary rope-like body such as a band steel 44b which is less elongated by a load and positioned within a range which is not brought into contact with the sheave 41a and the pulleys 42, 43.

Description

technical field [0001] The invention relates to a drive device for a double-deck elevator with two elevator cars, one upper and the lower, inside the car frame. Background technique [0002] In general, a double-deck elevator with two elevator cars up and down in the car frame is configured such that a drive device is arranged on the upper part of the upper car, and the sling is wound around the drive unit and placed on the upper car. Between the pulleys below the car and between the drive unit and the pulleys arranged under the car of the lower car, so that the upper car and the lower car are driven by the drive unit. [0003] In the above-mentioned double-deck elevator, when the load changes due to passengers getting into the elevator car or loading of goods, the amount of expansion and contraction of the sling varies as in a general elevator. In addition, the sling will be stretched after long-term use, so it is necessary to periodically adjust the length of the sling or...
