AI Technical Summary
Technical Problem
Existing escalator systems with multiple units driven by a single motor face challenges in flexible transport capacity adjustment and inefficient travel paths due to escalators rotating in the same direction and requiring passengers to change directions between floors.
Method used
A rotary switching device with a differential gear mechanism allows left and right shafts to rotate in the same or opposite directions, using a housing that moves axially to engage or disengage gears, enabling flexible switching between ascending and descending escalators.
Benefits of technology
Enables efficient travel paths with minimal distance changes between floors by allowing escalators to switch between ascending and descending modes, enhancing flexibility and reducing travel distance.

Abstract
The present invention provides a rotation switching device in which the left and right shafts can rotate in the same direction and in opposite directions. [Solution] A rotation switching device is provided, comprising a differential gear, a columnar housing containing it, a shaft to which a differential side gear is attached, a frame supporting the shaft, an external gear provided between the differential side gear and the end of the housing on the shaft, and an internal gear provided on one end of the housing that meshes with the external gear, wherein the housing moves left and right in the direction of the shaft by a movement function, causing the external gear and internal gear to disengage and the differential pinion gear and differential side gear to mesh and rotate, and the external gear and internal gear to mesh and the differential pinion gear disengage and rotate, causing the left and right shafts to rotate in the same direction and opposite directions.
