Definitions

  • This invention relates to an elevator apparatus in which the operation mode is switched to an on-car maintenance operation mode at the time of maintenance operation on the car and to a car movement regulating device used in the elevator apparatus and adapted to mechanically regulate the car movement during maintenance operation on the car.
  • Fig. 7 is a plan view showing the car movement regulating device of a conventional elevator apparatus disclosed, for example, in JP 2000-203774 A
  • Fig. 8 is a front view showing the car movement regulating device of Fig. 7.
  • a hoistway 1 in a hoistway 1, there are installed a pair of guide rails 3 for guiding the ascent and descent of a car 2.
  • Fixed to each guide rail 3 is a stationary plate 4 having an engagement hole 4a.
  • a bracket 6 is mounted to an upper beam 5 of the car 2.
  • a lock bar 7 is supported by the bracket 6.
  • the lock bar 7 is linearly reciprocated through manual operation between an engagement position (indicated by the broken line in the drawing) where its forward end portion is inserted into the engagement hole 4a and an accommodating position (indicated by the solid line in the drawing) where it is retracted to a position on the car 2.
  • An operating lever 8 for manually operating the lock bar 7 is mounted to the lock bar 7.
  • a retaining plate 9 for retaining the lock bar 7 at the engagement position and the accommodating position.
  • first and second grooves 9a and 9b are provided in the retaining plate 9 into which the operating lever 8 is inserted, respectively when the lock bar 7 is at the engagement position and at the accommodating position.
  • a limit switch 10 mounted to the bracket 6 is a limit switch 10 to be closed when the lock bar 7 is at the accommodating position.
  • An operating portion 10a of the limit switch 10 is operated by the rear end portion of the lock bar 7.
  • a hoist 11 for raising and lowering the car 2 is controlled by a control unit 12.
  • a control unit 12 there is provided a power circuit 13 for supplying power to the hoist 11.
  • the limit switch 10 is connected to the power circuit 13. When the limit switch 10 is closed, the power circuit 13 is in the ON state, and when the limit switch 10 is open, the power circuit 13 is in the OFF state.
  • the limit switch 10 only detects whether the lock bar 7 is at the accommodating position or not; it is impossible for it to detect whether the lock bar 7 has been appropriately moved to the engagement position, that is, whether the forward end portion of the lock bar 7 has been surely inserted into the engagement hole 4a. Further, it is impossible to detect that the forward end portion of the lock bar 7 is somewhere between the accommodating position and the engagement position. Thus, when the lock bar 7 is not at the accommodating position, it is only possible to perform a simple control to prevent the hoist 11 from being driven.
  • the hoist 11 can be driven with the lock bar 7 somewhere between the two positions, so that the lock bar 7 may interfere with an apparatus in the hoistway 1, thereby damaging the apparatus.

  • the operation mode is first switched to the on-car maintenance operation mode, and the car 22 is moved at low speed to a predetermined maintenance position. Thereafter, the arm 23 is rotated to the engagement position, and the hook portion 23a is engaged with the engagement hole 21a of the stationary plate 21, whereby the movement of the car 22 is regulated, and maintenance operation is performed on the car 22.

Normally, when the arm 23 is at the accommodating position, the second switch 27 is open, so that it is confirmed that the arm 23 is not at the engagement position, making it possible to operate the car 22 (step S4).
  • step S5 when it is detected that the arm 23 is at the engagement position although it has been detected that the arm 23 is at the accommodating position, it is determined that failure has occurred in the switch device 28, and an error detection signal is output (step S5).
  • both the first and second switches 26 and 27 are closed even if the arm 23 is at the accommodating position. In such a case, an error detection signal is output, and the switch device 28 is repaired or replaced by the operator.
