Abstract

Provided is a double-deck elevator wherein, when rope anchoring members from which a car positioned vertically in a car frame is suspended are moved by pressure-generating devices and rope elongation is corrected, a rope elongation correction amount is increased by providing raising bodies. This double-deck elevator is provided with a car frame (2), an upper car (12), a lower car (13), a car positioning adjustment drive device (11), and ropelike bodies (17), and is characterized in that one or both ends of each ropelike body (17): is suspended by anchoring members (26a, 26b); is attached to the car frame (2) via anchoring member moving devices (25a, 25b) that move the anchoring members (26a, 26b); and enable raising bodies (28), which support the bottom surfaces of the anchoring members (26a, 26b), to be attached to extension tips on the anchoring member moving devices (25a, 25b).

Description

technical field [0001] The invention relates to a double-deck elevator having a plurality of cars within a car frame. Background technique [0002] In a conventional double-deck elevator in which the upper and lower cars can move, a driving device is provided on the upper part of the car frame, pulleys are provided on the driving device, the lower car of the upper car, and the lower car, and Wind the sling around the pulley above. When a structure in which a sling is wound around a pulley is used, the length of the sling may become longer as the load changes, which may cause the floor position of the elevator car to change. Therefore, a method of correcting this has been proposed (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2007-331871 [0006] Summary of the invention [0007] The problem to be solved by the invention [0008] However, in the proposal discl...
