Problems solved by technology

In other words, there is a problem that it is difficult to ensure the necessary strength because a large and variable tensile force acts on the fixed part of the car position adjustment drive device.
In addition, when installing the driving device for adjusting the car position, it is necessary to fix it to the upper frame while making fine adjustments while the driving device for adjusting the car position is suspended. The problem of labor and time
In addition, since the upper limit position of the upper car when moving is limited by the lower end of the car position adjustment drive device, the height position of the lower part of the car position adjustment drive device to the height position of the lower part of the upper frame must be ensured. gaps, resulting in poor space utilization and resulting in increased weight

Abstract

The invention provides a double-deck elevator, wherein the installation position of a drive device for regulating the position of the elevator car is optimized. The double-deck elevator comprises a main frame (2) lifting in the elevating passage, an upper elevator car (8) arranged inside the main frame (2) capable of moving in a vertical direction, a lower elevator car (11) arranged inside the main frame (2) below the upper elevator car (8) capable of moving in a vertical direction and a drive device (13) for regulating the position of the elevator car arranged on the main frame (2) and equipped with a drive rope (13a) for regulating the position of the elevator car. The main frame (2) is formed by longitudinal frames (2a, 2b), an upper frame (2c), a middle frame (2d) and a lower frame (2e). The interval between the upper elevator car (8) and the lower elevator car (11) is adjusted by the up-down movement of the two elevator cars driven by an elevator car position adjusting rope (14). The drive device (13) for regulating the position of the elevator car is arranged above the upper frame (2c).

Description

technical field [0001] The invention relates to a double-deck elevator with upper and lower elevator cars in the main frame. Background technique [0002] As a prior art, for example, in Patent Document 1, a double-deck elevator in which the upper and lower elevator cars can move in the main frame is disclosed. The driving device is used, and the car position adjustment rope connected with the upper car and the lower car is wound on the car position adjustment driving sheave of the car position adjustment drive device, and the car position adjustment is passed through the car position adjustment. When the drive device is operated, the upper car and the lower car can be moved vertically by using the car position adjusting drive sheave and the car position adjusting rope to change the distance between them. [0003] Patent Document 1 Japanese Patent Application Laid-Open No. 2007-331871 (paragraph numbers 0008-0015, figure 1 ) [0004] However, in the above-mentioned conven...
