Double layer elevator and control method for double layer elevator

Abstract

Disclosed are a double layer elevator and a control method for the double layer elevator. The double layer elevator comprises at least two inner compartments arranged in an elevator compartment outer frame along the elevating direction in an elevating channel, a motor (10) lifting the elevator compartment outer frame (1), a hoist (4) and a compartment distance control device which regulate the distance between two inner compartments (3, 4) by moving at least one inner compartment, a compartment location detector (7) for detecting whether a compartment location diction plate is in opposite direction with compartment location detection plates (8) situated on locations corresponding to elevator lobbies on each story in the elevating channel, and a control device (12) for controlling the motion the double layer elevator. The control device controls the compartment distance control device according to predetermined distance to the inner compartment relative a target story, and stops the motor according to the state of the location detection plate detected by the compartment location detector so as to realize docking control.

Description

technical field [0001] The invention relates to a double-deck elevator and a control method for the double-deck elevator, in particular to a double-deck elevator and a control method for the double-deck elevator in which the stopping precision of the inner car is improved. Background technique [0002] As the prior art, for example, a double-deck elevator with a variable interval is disclosed in Patent Document 1, which can accurately detect whether the upper and lower cars are located in the respective elevator door opening and closing areas (for example, refer to the patent document 1). In the double-deck elevator disclosed in Patent Document 1, an elevator car outer frame position detection plate and an inner car position detection plate are arranged in the hoistway. In addition, an elevator car outer frame position detector that operates when facing the elevator car outer frame position detection plate is provided in the elevator car outer frame, and an elevator car out...

AI Technical Summary

Problems solved by technology

Therefore, the stopping positions of the upper and lower cars are equal, but it is difficult to improve the stopping accuracy of one of the upper and lower cars.

In addition, it is difficult to correct the height deviation between the floor and the elevator car caused by the expansion and contraction of the car support member when passengers enter and exit the elevator

In addition, the expansion and contraction of the car support members caused by passengers entering and exiting the elevator is particularly significant when the upper and lower cars are connected by ropes.
