Definitions
- the present invention relates to an elevator apparatus in which slippage of a suspending body relative to a driving sheave can be detected and a car can be stopped.
- an activating signal is generated by a safety control device if a car speed that is detected by a speed sensor exceeds a threshold value.
- a friction brake is pressed against a guide rail to brake the car (see Patent Literature 2, for example).
- Document EP1 749 780 presents an elevator system wherein slippage of the rope is detected based on signals from a sensor detecting rotation of a hasting pulley and a sensor detecting the perennial speed of the rope.
- the present invention aims to solve the above problems and an object of the present invention is to provide an elevator apparatus that can suppress damage to a suspending body due to excessive slippage of the suspending body relative to a driving sheave, and that can also prevent cumulative damage to a suspending body due to minute slippage of the suspending body.
- an elevator apparatus including: a hoisting machine that has a driving sheave; a suspending body that is wound around the driving sheave; a car that is suspended by the suspending body, and that is raised and lowered by the hoisting machine; a safety gear that is mounted to the car, and that makes the car perform an emergency stop in response to an activating signal; a first speed detector that generates a signal that corresponds to a rotational speed of the hoisting machine; a second speed detector that generates a signal that corresponds to a running speed of the car; and a slippage monitoring apparatus that computes a slippage extent value that is a value that relates to extent of slippage of the suspending body relative to the driving sheave based on the signals from the first and second speed detectors, and stops the car at a predetermined floor using the hoisting machine if the slippage extent value exceeds a first threshold value, and activates the safety gear by the activating
- FIG 1 is a structural diagram that shows an elevator apparatus according to Embodiment 1 (not claimed).
- a hoisting machine 1 is disposed in an upper portion of a hoistway.
- the hoisting machine 1 has: an electric motor 2; a driving sheave 3 that is rotated by the electric motor 2; and a hoisting machine brake 4 that brakes rotation of the driving sheave 3.
- the driving sheave 3 is linked directly to a rotating shaft of the electric motor 2, and is rotated together with the rotor of the electric motor 2.
- the hoisting machine brake 4 holds the electric motor 2 and the driving sheave 3 in a stopped state when rotation thereof is stopped (static holding).
- a first speed detector 5 that generates a signal that corresponds to rotational speed of the hoisting machine 1, i.e., rotational speed of the driving sheave 3, is disposed on the hoisting machine 1.
- An encoder that is disposed on the rotating shaft of the electric motor 2 (a hoisting machine encoder), for example, can be used as the first speed detector 5.
- a deflecting sheave 6 is disposed in a vicinity of the hoisting machine 1.
- a suspending body 7 is wound around the driving sheave 3 and the deflecting sheave 6.
- the suspending body 7 includes a plurality of main ropes. Ropes that have circular cross sections, or a belt that has a flat cross section, for example, can be used as the main ropes.
- a car 8 is connected to a first end portion of the suspending body 7.
- a counterweight 9 is connected to a second end portion of the suspending body 7.
- the car 8 and the counterweight 9 are suspended inside the hoistway by the suspending body 7, and are raised and lowered by the hoisting machine 1.
- a pair of car guide rails 10 that guide raising and lowering of the car 8 and a pair of counterweight guide rails that guide raising and lowering of the counterweight 9 (not shown) are installed in the hoistway.
- a safety gear 11 that makes the car 8 perform an emergency stop by engaging with the car guide rails 10 is mounted to a lower portion of the car 8.
- the safety gear 11 has an emergency stopper driving portion 11 a for activating the safety gear 11 in response to an electric activating signal.
- An electromagnetic actuator for example, can be used as the emergency stopper driving portion 11a.
- a speed governor 12 is disposed in an upper portion of the hoistway.
- the speed governor 12 has a speed governor sheave 13 and a rope gripping apparatus 14.
- a speed governor rope 15 is wound around the speed governor sheave 13. Two end portions of the speed governor rope 15 are coupled to the safety gear 11 by means of a coupling rod 16.
- a lower end portion of the speed governor rope 15 is wound around a tension sheave 17 that is disposed in a lower portion of the hoistway.
- the speed governor rope 15 is cycled together with the raising and lowering of the car 8.
- the speed governor sheave 13 is thereby rotated at a speed that corresponds to the running speed of the car 8. If the running speed of the car 8 reaches a preset first overspeed, this is detected by the speed governor 12, and the car 8 is urgently stopped by the hoisting machine 1. At that point, passage of electric current to the electric motor 2 is interrupted and rotation of the electric motor 2 and the driving sheave 3 is also braked by friction from the hoisting machine brake 4.
- the running speed of the car 8 reaches a preset second overspeed (the second overspeed is greater than the first overspeed)
- this is detected by the speed governor 12, and the speed governor rope 15 is gripped by the rope gripping apparatus 14, stopping circulation of the speed governor rope 15.

- a second speed detector 18 that generates a signal that corresponds to rotational speed of the speed governor sheave 13, i.e., a signal that corresponds to the running speed of the car 8, is disposed on the speed governor 12.
- An encoder that is disposed on the rotating shaft of the speed governor sheave 13 (a speed governor encoder), for example, can be used as the second speed detector 18.
- the signals from the first and second speed detectors 5 and 18 are input into a safety gear actuating command apparatus 19 that constitutes a slippage monitoring apparatus. Based on the signals from the first and second speed detectors 5 and 18, the safety gear actuating command apparatus 19 computes a slippage extent value that is a value that relates to an extent of slippage of the suspending body 7 relative to the driving sheave 3. In Embodiment 1, the safety gear actuating command apparatus 19 computes slippage speed of the suspending body 7 relative to the driving sheave 3 as the slippage extent value.
- the safety gear actuating command apparatus 19 stops the car 8 at a predetermined floor using the hoisting machine 1 if the slippage speed of the suspending body 7 exceeds a first speed threshold value (a first threshold value). In addition, the safety gear actuating command apparatus 19 outputs an activating signal to the emergency stopper driving portion 11 a if the slippage speed of the suspending body 7 exceeds a second speed threshold value (a second threshold value) that is greater than the first speed threshold value.

- the slippage determining portion 21 compares the slippage speed that has been found by the slippage speed computing portion 20 with the first and second speed threshold values, and outputs commands to various kinds of safety system actuating portions 22 in response to the compared results and elevator operating conditions.

If an emergency stop signal has not been issued, determine whether or not the slippage speed exceeds the first speed threshold value Va (Step S2). If the slippage speed is less than or equal to the first speed threshold value Va, continue normal operation.
