  BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a guide rail holding device for an elevator according to the present invention and an elevator including the same will be described below with reference to the drawings.

(Elevator 100)
As shown in FIGS. 1 and 2, in the elevator 100, a hoisting machine 200 is installed below the hoistway.

  One end of the main rope 220 wound around the drive sheave 210 of the hoisting machine 200 is fixed in the hoistway via the first car sheave 232 and the second car sheave 233 attached to the car 230 There is.

  The other end of the main rope 220 is fixed in the hoistway via a counterweight sheave 241 attached to the counterweight 240.

  When the drive sheave 210 is rotationally driven by the motor (not shown) of the hoisting machine 200, the main rope 220 travels accordingly. Then, the car 230 on which the first car sheave 232 and the second car sheave 233 are attached is guided by the car guide rail 300a to move up and down in the hoistway.

  Similarly, as the main rope 220 travels, the counterweight 240 to which the counterweight sheave 241 is attached is guided by the counterweight guide rail 300b to ascend and descend in the hoistway.

  The traveling direction of the main rope 220 is changed by the first sheave 211 and the second sheave 212.

  The elevator 100 is provided with a governor 400 that mechanically detects that the elevation speed of the car 230 exceeds a predetermined speed. An endless governor rope 600 is wound around the governor sheave 410 of the speed governor 400 and the tension sheave 500 located below the governor sheave 410.

  The governor rope 600 is stretched in tension in parallel with the main rope 220 by a tension sheave 500. A part of the governor rope 600 is fixed to a safety lever 250 for operating a safety gear 231 provided on the side of the car 230.

  Therefore, the governor rope 600 travels at the same speed as the car 230 in synchronization with the elevation of the car 230. At this time, the speed governor 400 detects the rotational speed of the governor sheave 410, which is rotated at the same speed as the traveling speed of the governor rope 600, so that the speed exceeding of the cage 230 is detected.

  When the elevator speed of the car 230 reaches a first speed exceeding the rated speed (predetermined speed), a motor (not shown) constituting the hoisting machine 200 of the main rope 220 is braked.

  If the car 230 does not stop even if the motor (not shown) is braked, a movable second grip (not shown) by the trip lever (not shown) of the governor sheave 410 is reached when the second speed exceeds the first speed. The support is released, and the traveling of the governor rope 600 is stopped by the movable grip.

  Then, the safety locking lever 250 fixed to the governor rope 600 is pulled up relatively by the governor rope 600 and pulled up relatively. As a result, the safety gear 231 operates.

  If the car 230 does not stop even when the safety gear 231 is activated, the car 230 collides with the first oil buffer 700a, which is the oil buffer 700 disposed below. The first oil buffer 700 a absorbs the impact of the cage 230 and stops the cage 230.

  A second oil buffer 700 b, which is an oil buffer 700, is disposed below the counterweight 240. When the counterweight 240 falls, the second oil buffer 700 b absorbs the impact due to the drop of the counterweight 240 and stops the counterweight 240.
