- the passive shoe 14 on the opposite side of the second shoe 13 has its braking surface 14a pressed against the guide rail 3, and the pressing force of the shoes on both sides raises the braking force. Stop one. Also, as in the case of abnormal acceleration in the downward direction, the guide rail 3 of the passive side shoe 14 is adjusted by adjusting the panel force setting of the spring 19 provided on the back surface 14 b of the passive side shoe 14. The deceleration of the elevator car 1 is adjusted by adjusting the pressing force of the elevator car 1.
- the pin 6 is passed through the long hole 12 c of the first shoe 12 and the long hole 5 c of the lever 5 and is fixed to the second shoe 13, so that the two Only one lever is required to drive one (show 1 and 2).
- the braking device of the first embodiment according to the first embodiment basically follows the structure in which only one shoe is movable similarly to the conventional braking device, and moves the movable-side shoe up and down.
- the number of parts is not significantly increased, and the structure is not complicated.
- a braking device that also operates can be obtained.
- productivity can be improved.
- FIG. 5 is a diagram illustrating a shape of a movable-side shoe of the braking device for an elevator according to the second embodiment.
- (A) is a diagram showing the positional relationship of the car when the elevator car is normally raised and lowered and when the braking device operates during abnormal downward acceleration, and the diagram on the left shows the car.
- the elevation view seen from the braking surface side is the side view of the show.
- (B) is a side view showing a positional relationship of the shoe in a state where the braking device is operated at the time of abnormal upward acceleration.
- the braking device for the elevator includes a bottom surface 18 of a storage groove 17 formed in the first shoe 12 and a rear surface of the second shoe 13. Roller 21 is interposed between .13b.
- Other configurations and operations are the same as those of the first embodiment, and therefore, the same or equivalent portions are denoted by the same reference numerals and description thereof will be omitted.
- the braking surface 1 is increased to increase the braking force of the shoe 13.
- the elevator braking apparatus can be operated not only at the time of abnormally increasing speed of the elevator in the downward direction but also at the time of abnormally increasing speed of the elevator. Therefore, for example, when the elevator weight is heavier than the elevator car due to the small number of passengers, and the elevator car abnormally accelerates upward due to a failure in the elevator equipment, the elevator is lifted. Since the evening basket can be stopped reliably, it is useful as an even more secure elevator.
- the braking device of the present invention suppresses an increase in the number of parts compared to the conventional braking device, and is capable of operating for abnormally increasing speed in both the up and down directions without complicating the structure. Therefore, it is useful as an elevator with improved productivity.
