Definitions

  • Fig. 2 is a perspective view explaining an operational mechanism of the emergency-stop device 5 according to Embodiment 1 of the invention
  • Fig. 3 is a right side view of Fig. 1 representing the emergency-stop device 5.
  • the operation lever 6 is a long-length (rectangular) member, and a lift-up rod 24 extending in a direction that the car moves up and down is attached to one end of the operation lever 6, while an upper pivot axis 11 is fixed in a parallel direction to the other end thereof.
  • the governor rope 7 is an endless rope wound around a governor sheave (unillustrated) of a governor arranged in a top portion of the hoistway, and around a governor tension pulley arranged near a lower pit, and, when the governor detects abnormality in a descending speed of the car 2, the governor holds the governor rope 7 to stop its circulation. That is, when the car 2 moves in the up-and-down direction, the governor rope 7 moves with the car 2, and the governor sheave rotates in response to the movement of the car 2; however, when a rotation speed of the governor sheave, in the downward direction becomes excessive, the governor holds the governor rope 7.
  • the operation lever 6 is operated by displacement of the car 2 toward the governor rope 7 due to the governor rope 7 being held by the governor.
  • Each of the lower wedges 16 is arranged between each of the lower guides 17 and the car guide rail 1.
  • Each of the lower wedges 16 is guided along the lower guides 17 in a direction to contact the car guide rail 1 due to relative displacement in the upward direction with respect to the emergency-stop mounting frame 10, while guided along the lower guides 17 in a direction to depart from the car guide rail 1 due to relative displacement in the downward direction with respect to the emergency-stop mounting frame 10.
  • Each of the lower wedges 16 is arranged to face each other sandwiching the car guide rail 1 therebetween, and slides on the car guide rail 1 to brake the car 2.
