A governor rope 12 is looped around the upper pulley 10 and the lower pulley 11. Both ends of the governor rope 12 are connected to the car 1.

  • the safety controller 15 controls energization of the brake coil 21 to control the braking force of the brake device 7.
  • the safety controller 15 controls the braking force of the brake device 7 by intermittently applying the braking force of the brake device 7 so that a deceleration of the car 1 does not become excessively high when the car 1 is brought to an emergency stop.

  • the first safety circuit 23 includes at least one first safety switch 25 connected in series.
  • the first safety circuit 23 detects an abnormal state based on opening of the first safety switch 25 to generate a car stop command to the brake device 7. Specifically, when the at least one first safety switch 25 is opened while the car 1 is running, the brake contactor 22 is de-energized. As a result, the hoisting-machine motor 6 is de-energized and the brake coil 21 is also de-energized to bring the car 1 to a sudden stop.
  • a second safety circuit (auxiliary safety circuit) 24 is provided between the brake contactor 22 and the power supply so as to be in parallel to the first safety circuit 23.
  • the brake contactor 22 and the second safety circuit 24 are disconnected from each other at normal time.

  • the second safety circuit 24 detects the same type of abnormal state as that detected by the first safety circuit 23 based on opening of the second safety switch 26 to generate a car stop command to the brake device 7. At the normal time, however, the second safety circuit 24 is disconnected from the brake contactor 22 and placed in a standby state. Therefore, the car stop command is not transmitted to the brake contactor 22.
  • the first safety switch 25 and the second safety switch 26 corresponding thereto, specifically, the second safety switch 26 which has the same target to monitor, are always in the same open/closed state unless a failure occurs in the first and second safety switches.
  • Examples of the first safety switch 25 and the second safety switch 26 include an upper hoistway switch, a lower hoistway switch, a car door opening detection switch, a landing door opening detection switch, and an overspeed detection switch.
  • a safety circuit to be connected to the brake contactor 22 is switched between the first safety circuit 23 and the second safety circuit 24 by a switching device 27.
  • the switching device 27 includes an electromagnetic relay 28 and a semiconductor switch 29 which is an electric switch connected in series to the electric relay 28.
  • the electromagnetic relay 28 is provided between the first safety circuit 23 and the brake contactor 22, and between the second safety circuit 24 and the brake contactor 22, to selectively connect the first safety circuit 23 and the second safety circuit 24 to the brake contactor 22.
  • the semiconductor switch 29 energizes and de-energizes a coil of the electromagnetic relay 28.
  • the semiconductor switch 29 is controlled to be turned ON/OFF by a failure detecting section 30.
  • the failure detecting section 30 detects faulty opening which corresponds to opening of the first safety switch 25 due to a failure, based on the state of the first safety switch 25 and the state of the second safety switch 26. Specifically, the failure detecting section 30 compares the states of the first safety switch 25 and the second safety switch 26 (which have the same target to monitor), which are opened when the same type of abnormal state occurs, and detects a state in which the first safety switch 25 is opened while the second safety switch 26 is closed as the faulty opening.
  • the failure detecting section 30 is provided to the safety controller 15. Functions of the failure detecting section 30 are realized by the microcomputer or the logic circuit of the safety controller 15.
  • the switching device 27 connects the first safety circuit 23 to the brake contactor 22 and disconnects the second safety circuit 24 from the brake contactor 22.
  • the switching device 27 switches the circuit to be connected to the brake contactor 22 from the first safety circuit 23 to the second safety circuit 24.
  • a circuit switching time period T1 for switching between the first safety circuit 23 and the second safety circuit 24 by the switching device 27 is set shorter than a time period T2 from the opening of the first safety switch 25 to the actual start of a braking operation of the brake device 7 (T1 ⁇ T2).
  • T2 is generally about 50 to 100 milliseconds depending on the specifications of the brake contactor 22.
  • T1 is set so as to satisfy T1 ⁇ T2 in consideration of an error.
  • the electromagnetic relay 28 is selected based on an estimate value of a time period required for the detection performed by the failure detecting section 30 and operation specifications of the semiconductor switch 29.
  • the second safety circuit 24 is disconnected from the brake contactor 22, whereas the first safety circuit 23 is placed in a valid state. Then, when the at least one first safety switch 25 is opened due to some abnormality occurring in the elevator, the hoisting-machine motor 6 is de-energized and the brake coil 21 is also de-energized to bring the car 1 to a sudden stop.
  • the failure detecting section 30 always monitors whether or not the faulty opening of the first safety switch 25 occurs. Then, when the faulty opening is detected, the semiconductor switch 29 is turned OFF to de-energize the electromagnetic relay 28. In this manner, the circuit tobe connected to the brake contactor 22 is instantaneously switched from the first safety circuit 23 to the second safety circuit 24.
  • the elevator can travel without bringing the car 1 to a sudden stop even when the faulty opening of the first safety switch 25 is detected. Specifically, even when a failure occurs in the first safety circuit 23 which is in operation, the switching to the second safety circuit 24 which is in a standby state is instantaneously performed. Therefore, a safety travel can be performed without bringing the car 1 to a sudden stop.
  • the failure detecting section 30 compares the states of the first safety circuit 25 and the second safety circuit 26, which are opened when the same type of abnormal state occurs, and detects the state in which the first safety circuit 25 is opened while the second safety switch 26 is closed as the faulty opening. Therefore, the failure of the first safety circuit 23 can be detected with high accuracy.
  • the brake contactor 22 is de-energized so that the hoisting-machine motor 6 and the brake coil 21 are de-energized by a mechanical switch. Therefore, the car 1 can be more reliably stopped.
  • the semiconductor switch 29 is turned OFF.
  • the switching between the circuits can be performed at a high speed.
  • the operation of the elevator can be continued after the switching to the second safety circuit 24. However, it is preferred that the operation of the elevator be interrupted to perform inspection work after a maintenance center or the like is notified of the failure of the first safety circuit 23 and the car 1 is stopped at a predetermined floor.
  • the elevator may be operated while the second safety circuit 24 is operated only until the inspection work is started by a maintenance worker.
  • first safety switch 25 and the second safety switch 26 are not necessarily required to correspond to each other exactly on a one-to-one basis.
  • the number of the second safety switches 26 may be larger than that of the first safety switches 25.
  • the number of targets to be monitored by the second safety circuit 24 may be larger than that of targets to be monitored by the first safety circuit 23.
  • a part of the targets to be monitored may be allocated to the safety controller 15 at the normal time so as to be monitored.
  • a configuration of a safety circuit device for an elevator according to the second embodiment is basically the same as that of the first embodiment.
  • the switching device 27 connects the second safety circuit 24 to the brake contactor 22 and then disconnects the first safety circuit 23 from the brake contactor 22, as illustrated in FIG. 5 .
  • the switching device 27 performs switching between the first safety circuit 23 and the second safety circuit 24 so that the circuits are not simultaneously placed in a standby state.
  • the elevator can travel without bringing the car 1 to a sudden stop even when the faulty opening of the first safety switch 25 is detected.
  • the brake device 7 which brakes the rotation of the driving sheave 5 to brake the car 1 is described.
