TRACTION ELEVATOR ROPE MOVEMENT SENSOR SYSTEM

摘要

An elevator system constructed in accordance to one embodiment of the present disclosure includes an elevator car, a counterweight, a sheave assembly, a suspension rope, a compensation rope, a first optical sensor assembly and a controller. The suspension rope has a first suspension end coupled to the elevator car and a second suspension end coupled to the counterweight. The first compensation rope has a first compensation end coupled to the elevator car and a second compensation end coupled to the counterweight. The first optical sensor assembly can have a first optical sensor pair including a first emitter and a first receiver. The first emitter is configured to emit a first beam to be received by the first receiver. The first optical sensor pair is configured to detect interruption of the first beam by the first compensation rope. The controller controls movement of the elevator car based on the detected interruption.

主权项

1. An elevator system comprising:
an elevator car; a counterweight; a sheave assembly having a suspension sheave portion and a compensation sheave portion that guides the elevator car on a car side of the sheave assembly and guides the counterweight on a counterweight side of the sheave assembly; a suspension rope passing over and guided by the suspension sheave portion, the suspension rope having a first suspension end coupled to the elevator car on the car side and a second suspension end coupled to the counterweight on the counterweight side; a first compensation rope passing around the compensation sheave portion, the first compensation rope having a first compensation end coupled to the elevator car on the car side and a second compensation end coupled to the counterweight on the counterweight side; a first optical sensor assembly having a first optical sensor pair including a first emitter and a first receiver, the first emitter configured to emit a first beam to be received by the first receiver, the first optical sensor pair configured to detect interruption of the first beam by the first compensation rope; and a controller that controls movement of the elevator car based on the detected interruption.
