Definitions
- the present invention relates to a tensioning device for a governor rope for an elevator for applying tension to a governor rope that is moved together with a force.
- a tension wheel and a weight may be suspended from the governor rope in order to apply tension to the governor rope.
- the governor rope is wound around a tensioned vehicle and the weight is attached to the tensioned vehicle.
- a fixed member is attached to the car guide rail for guiding the lifting and lowering of the force by a rail clip.

At this time, the rotational directions of the governor sheave 13 and the tension wheel 23 are also repeatedly reversed as the governor rope 16 moves in the vertical direction.
- the tension wheel 23 can be prevented from being displaced upward, and a sudden decrease in the magnitude of the tension applied to the governor rope 16 can be prevented. Therefore, even when the car 3 swings up and down, the roll of the governor rope 16 can be prevented, and the lifting speed of the force 3 is controlled by the rotational speed of the governor sheave 13. Can be detected with high accuracy. In addition, for example, malfunction of the emergency stop device 15 or catching of the governor rope 16 on other devices can be prevented.
- the protruding pin 27 is arranged above the arm 22! Therefore, it is possible to arrange the protruding pin 27 between the support shaft 21 and the tensioning wheel 23 in the horizontal direction.
- the length of the arm 22 can be shortened. As a result, the material cost can be reduced and the space can be saved.
- the force projecting pin 27 may be disposed below the arm 22.
- the force projecting pin 27 may be disposed above the arm 22.
- the protruding pin 27 is arranged on the side farther from the tensioning wheel 23 than the support shaft 21 in the horizontal direction. Even in this case, when the arm 22 is rotated in the direction in which the tension wheel 23 is displaced upward, the distance between the projecting pin 27 and the arm 22 can be reduced, and the projecting By pushing the wedge 29 between the pin 27 and the arm 22, the upward displacement of the tensioning wheel 23 can be prevented. Further, the wedge 29 and the tension spring 34 increase in size because the displacement of the wedge 29 increases as the distance in the horizontal direction between the protruding pin 27 and the support shaft 21 increases. Therefore, in order to reduce the size, it is desirable to reduce the horizontal distance between the protruding pin 27 and the support shaft 21.
