SAFETY APPARATUS FOR AN ELEVATOR APPARATUS AND A DRIVE APPARATUS THEREOF

摘要

A safety apparatus for elevator apparatuses which can move a cab via a drive including a monitoring unit for monitoring at least one of the drive and/or the motor regulation system of the drive, a safety device having at least two sensors, which can be switched between at least two switching states depending on a state, in particular a closing state. In order to be able to reduce operating costs, at least one of the safety device and the monitoring unit includes a controller, which is designed to identify the respective switching states of the sensors, and to transmit at least one of data and monitoring signals to the monitoring unit.

1. A safety apparatus for an elevator apparatus which can move a cab via a drive, comprising:
a monitoring unit for monitoring at least one of the drive and a motor regulation system of the drive, a safety device having at least two sensors that are switched between at least two switching states depending on a state of the elevator apparatus, wherein at least one of the safety device and the monitoring unit comprises a controller that identifies the respective switching states of the sensors, and transmits at least one of data and monitoring signals to the monitoring unit, wherein at least one of the sensors comprises a contact link and a contact receptacle for receiving the contact link, which contact link and contact receptacle are arranged such that the closing state of an elevator door can be determined by connection of the contact receptacle and the contact link, wherein the sensor is in the form of an optical sensor comprising a transmitter for transmitting an optical signal and a receiver for receiving the optical signal, and wherein the transmitter and the receiver are arranged on the contact receptacle, and the contact link comprises at least one transmission element for transmitting the optical signal.
