Definitions

  • the present invention relates to an elevator apparatus allowing the deceleration of a car at a time of emergency braking to be adjusted.
  • the braking force of an electromagnetic brake is controlled at the time of emergency braking such that the deceleration of a car becomes equal to a predetermined value, based on a deceleration command value and a speed signal (for example, see Patent Document 1).
  • Patent Document 1 JP 07-157211 A
  • the present invention has been made to solve the above-mentioned problem, and it is therefore an object of the present invention to obtain an elevator apparatus allowing the car to be stopped more reliably even in the event of a malfunction in a brake control portion while suppressing the deceleration at the time of emergency braking.
  • An elevator apparatus includes: a car; and a brake device for stopping the car from running, in which the brake device has a brake control portion for controlling a braking force generated at a time of emergency braking to adjust a deceleration of the car; and a timer circuit for invalidating control of the braking force performed by the brake control portion after a lapse of a predetermined time from a moment when an emergency braking command is generated.
  • Fig. 1 is a schematic diagram showing an elevator apparatus according to Embodiment 1 which is part of the disclosure, but not part of the present invention.
  • a car 1 and a counterweight 2 are suspended within a hoistway by a main rope 3.
  • the car 1 and the counterweight 2 are raised/lowered within the hoistway due to a driving force of a hoisting machine 4.
  • the hoisting machine 4 has a drive sheave 5 around which the main rope 3 is looped, a motor 6 for rotating the drive sheave 5, a brake drum 7 as a brake rotational body that is rotated integrally with the drive sheave 5 as the car 1 runs, and a brake portion body 9 for braking rotation of the drive sheave 5.
  • the driving of the motor 6 is controlled by a drive control portion 10 as an operation control portion.
  • the brake portion body 9 has a brake shoe 15 that is brought into contact with and away from the brake drum 7, an armature 16 mounted on the first brake shoe 15, a braking spring 17 for pressing the brake shoe 15 against the brake drum 7, and a brake coil 18 disposed facing the armature 16 to generate an electromagnetic force for opening the brake shoe 15 away from the brake drum 7 against the braking spring 17.
  • a brake switch 22 and a timer switch 28 are connected in series between the brake coil 18 and a power supply 19. By opening at least one of the switches 22 and 28, the supply of a power to the brake coil 18 is shut off, so the brake shoe 15 is pressed against the brake drum 7 by the braking spring 17.
  • the timer switch 28 is normally closed. Accordingly, during normal operation, when the brake switch 22 is closed, the brake coil 18 is thereby supplied with a power, so the brake shoe 15 is opened away from the brake drum 7.
  • the turning ON/OFF of the brake switch 22 is controlled by a brake control portion 23.
  • the brake control portion 23 is constituted by a microcomputer having a calculation processing portion (a CPU), a storage portion (a ROM, a RAM, and the like), and signal input/output portions.
  • the brake control portion 23 When a brake actuation command (including a normal braking command and an emergency braking command) is generated, the brake control portion 23 opens the brake switch 22, and shuts off the supply of a current to the brake coil 18 to cause the brake portion body 9 to perform braking operation.
  • the brake control portion 23 closes the brake switch 22 to cancel a braking force of the brake portion body 9.
  • the brake actuation command and the -brake opening command are generated by an elevator control portion including the drive control portion 10, and then input to the brake control portion 23.
  • the brake control portion 23 estimates a deceleration (the absolute value of a negative acceleration) of the car 1 based on deceleration estimation information for estimating the deceleration of the car 1, and controls an electromagnetic force generated by the brake coil 18 (an open/closed state of the brake switch 22) such that the deceleration of the car 1 does not become excessively high or low.
  • the brake control portion 23 controls a pressing force with which the brake shoe 15 is pressed against the brake drum 7.
  • a hoisting machine rotation detector for detecting rotation of the motor 6, a car position detector provided on a speed governor, a return pulley rotation detector for detecting rotation of a return pulley around which the main rope 3 is looped, a weighing device for detecting a load within the car 1, a speedometer mounted on the car 1, an accelerometer mounted on the car 1, an axial torque meter for detecting an axial torque of the drive sheave 5, or the like.
  • the rotation detectors and the car position detector are encoders or resolvers.
  • the second brake switch 22 is a switch allowing the amount of the current supplied to the brake coil 18 to be adjusted, for example, an open/close switch capable of chopping or a slide switch for continuously changing a resistance value.
  • an open/close switch capable of chopping or a slide switch for continuously changing a resistance value for example, an open/close switch capable of chopping or a slide switch for continuously changing a resistance value.
  • the switch is slid to change the resistance value instead of being turned ON/OFF.
  • the timer switch 28 is opened in response to an opening command from a timer circuit 29.
  • the timer circuit 29 starts measuring (counting down) a time, and outputs the opening command to the timer switch 28 after the lapse of a predetermined time from a moment when the brake actuation command is generated. Accordingly, the control of the braking force of the brake portion body 9 performed by the brake control portion 23 is invalidated after the lapse of a predetermined time from a moment when an emergency braking command is generated.
  • a brake device in Embodiment 1 of the present invention has the brake portion body 9, the brake switch 22, the brake control portion 23, the timer switch 28, and the timer circuit 29.
  • the control of braking force performed by the brake control portion 23 is invalidated after the lapse of the predetermined time from the moment when the emergency braking command is generated. It is therefore possible to stop the car 1 more reliably even in the event of a malfunction in the brake control portion 23 while suppressing the deceleration of the car 1 at the time of emergency braking.
  • Fig. 2 is a schematic diagram showing an elevator apparatus according to Embodiment 2 which is part of the disclosure, but not part of the present invention.
  • a current limiter 27 and a changeover switch 27a are connected between the brake coil 18 and the power supply 19.
  • the current limiter 27 limits the current flowing through the brake coil 18.
  • Employed as the current limiter 27 is, for example, a resistor.
  • the changeover switch 27a makes a changeover between an operation of limiting a current from the power supply 19 by means of the current limiter 27 to supply the brake coil 18 with the limited current and an operation of supplying the brake coil 18 with the current from the power supply 19 without the intermediation of the current limiter 27.
  • the changeover switch 27a has normally been changed over to a circuit side from which the current limiter 27 is excluded. In this state, when a brake actuation command is generated, the changeover switch 27a is changed over to a circuit side including the current limiter 27. When the brake actuation command is canceled, the changeover switch 27a is returned to the circuit side from which the current limiter 27 is excluded.
  • Embodiment 2 of the present invention is identical to Embodiment 1 of the present invention in other configurational details and other operational details.
  • the current limiter 27 is employed to set an upper limit of the amount of the current supplied to the brake coil 18 which can be controlled by the brake control portion 23, so only part of a power-supply voltage is applied to the brake coil 18. Accordingly, it is possible to suitably limit the amount of the control of the brake portion body 9 performed by the brake control portion 23.

  • the brake portion body 9 is forced to perform braking operation regardless of a command from the brake control portion 23. That is, the forcible braking switch 26 invalidates the control of braking force performed by the brake control portion 23 in response to an external signal, thereby forcing the brake portion body 9 to generate a total braking force.
  • Embodiment 3 of the present invention is identical to Embodiment 2 of the present invention in other configurational details and other operational details.
  • the forcible braking switch 26 is provided between the brake coil 18 and the power supply 19. It is therefore possible to invalidate the control performed by the brake control portion 23 according to need and cause the brake portion body 9 to perform braking operation immediately.
