の先端に引上げロッド１３ａの上端が連結されている。Further, as shown in FIG. 4, a connecting portion 8a provided on the governor rope 8 and the tip of the aforementioned operating lever 9 are connected via a pin 10. The actuating lever 9 has a shaft 11 that is rotatably supported by the bracket 4a in a vertical plane.
is provided integrally with the A stop device 5 disposed below the operating lever 9 includes a pulling rod 1 whose upper end is connected to a lever 12 fixed to a shaft 11, as shown in the fifth jump.
3, a pair of steel wedge members 14 that are supported by this pulling rod 13 and can be held on a guide rail (not shown), and guide the wedge members 14 in a direction toward each other as these wedge members 14 rise. The guide device 15 includes a U-shaped spring steel member 16 that can apply force to the wedge members 14 in a direction in which they approach each other via the guide device 15. The other stopping device 5a has a similar configuration, and this stopping progress i5
4, a lever 12b is fixed to the shaft 11, a connecting rod 17 has one end connected to the tip of the lever 12b, and a tip connects to the other end of the connecting rod 17. a lever 18 supported by the bracket 1-42 so as to be rotatable in a vertical plane, and a lever 20 fixed to the shaft 19 via a shaft 19 on which the lever 18 is integrally provided.
The upper end of the pulling rod 13a is connected to the tip of the pulling rod 13a.

れる。Furthermore, an interlocking body that interlocks with the actuation lever 9, such as a rod 25, is connected to the tip of a lever 12a that is fixed to the shaft 11. A holding means, for example, the holding device 21, which is attached to the bracket 4a of the counterweight 4 and capable of holding one end of the rod 25, is fixed to a pair of plate members, such as the bracket 4a, capable of holding the end 25a of the rod 25. a movable plate 23 that is rotatably supported by the plate 22 at an end separated from the rod 25; and a force that applies an elastic force to the movable plate 23 in a direction toward the plate 22. For example, a coil spring 24 biases a spring force of about 200 to 300 kg. During normal operation, one end 25a of the rod 25 is held by the holding bag W21, and the operating lever 9 is held at a predetermined position shown in FIG.

。Since the rotation of the operating lever 9 is thus prevented,
The relative height relationship between the counterweight 4 and the connecting portion 8a of the governor rope 8 is kept constant, and therefore the lifting speed of the counterweight 4 and the moving speed of the governor rope 8 are equivalent. In addition, the above-mentioned stop device 5.5a, speed governor 6, tension wheel 7, governor rope 8, operating lever 9, bin 10, shaft 11°19, levers 12.12a, 12b,
18.20, the rod 17.degree. 25, and the holding device 21 constitute a conventional emergency stop device for an elevator.

板材２２、可動板材２３より離脱する。In such a conventional elevator emergency stop device, when the descending speed of the counterweight 4 exceeds a predetermined speed and reaches a dangerous state, the moving speed of the governor rope 8 equivalent to this descending speed is detected. The governor 6 catches the governor rope 8, and the governor rope 8 stops. On the other hand, the counterweight 4, which has a larger inertia than the governor rope 8, tries to continue descending, so a force is applied to the operating lever 9 to rotate it upward from the predetermined position shown in FIG. Rod 2 through 12a
5 is given a force to move to the right in FIG. and,
The end portion 25a of the rod 25 moves between the plate material 22 and the movable plate material 23 against the spring force of the coil spring 24, and is separated from the plate material 22 and the movable plate material 23.
このとき、作動レバー９は第４図の１点鎖線で示す位置
へ回動している。At this time, the operating lever 9 has rotated to the position shown by the dashed line in FIG.

４が徐々に制動され、停止するようになっている。Further, force is applied by the spring steel material 16 in a direction in which the wedge members 14 approach each other, and the wedge members 14 gradually pinch the guide rail. At the same time, the other pulling rod 13a with the stop value R5a also moves the shaft 11, the lever 12b, the connecting rod 17, and the lever 18.
, shaft 19, and lever 20, and the stop device 5a is similarly activated. As a result, the Kalancraate 4 is gradually braked and comes to a stop.

。By the way, in the conventional elevator emergency stop device as described above, in order to push up the movable plate 23 against a spring force of about 200 to 300 kg, a large amount of human power of at least about 50 kg is applied using tools such as spanners and levers. Also, while maintaining this state, the plate material 22.2
When inserting the end portion 25a of the rod 25 between the two holes, there is a problem in that it is dangerous and extremely difficult for a second worker to insert the end portion 25a of the rod 25 between the two holes.
本発明はこのような従来技術における実情に濫みてなさ

A return means, for example, a jig 30, is provided for returning the rod 25, which has been detached from the holding device 21 with the rotation of the operating lever 9 shown in the figure, to a predetermined state in which the holding device 21 holds it. As shown in FIG. 2, the heath 31 of this jig 30 has a U-shaped cross section, and is installed so as to sandwich the plate 22 of the holding device 21. A plate 31a, an upper plate 31b disposed above the plate material 22, a lower plate 31a thereof, and a plate plate 31.
It consists of a vertical plate 31C that connects b. and,
The fixing bolt 32 and the push-up bolt 33 are screwed into the upper plate 31b, and the tip of the fixing bolt 32 presses the upper surface of the plate 22, thereby fixing the base 31 to the plate 22.

手段が治具３０に備えられている。Further, a guide plate 34 capable of guiding the end portion 25a of the rod 25 is attached to the upper surface of the portion of the lower plate 31a that protrudes from the plate material 22 toward the right in FIG. This guide plate 3
4 has a thickness similar to that of the plate 22 near the plate 22, and is formed so that the thickness decreases as it protrudes from the plate 22, and the end 2 of the rod 25
The length of the guide plate 34 is set so that the end 25a of the rod 25 is located on the inclined surface 35 of the guide plate 34 when the rod 5a is separated from the plate 22 and the movable plate 23. Note that the rotating plate 23 is attached to the pin 3 at the left end in FIG.
6, and these plates 22 and movable plate 23 are connected to the end 25 of the rod 25 at the right end in FIG.
It is possible to hold a. Further, the base 31 and the push-up bolt 33 constitute an actuating means that is attached to the plate 22 and the movable plate 23 and separates the movable plate 23 from the plate 22 against the spring force of the coil spring 24. The jig 30 is provided.

In order to return to the state in which the end portion 25a of the rod 25 is held between the movable plate members 23, the operator must push the jig 3o -1-
The push-up bolt 33 is rotated to raise the push-up bolt 33 such that the distance between the plate member 22 and the movable plate member 23 at a predetermined position becomes larger than the height dimension of the end portion 25a of the rod 25. Next, the operating lever 9 is returned to the predetermined position, and the rod 2 located on the inclined surface 35 of the guide plate 34 is
5 along this inclined surface 35,
It is arranged at a predetermined position between the plate material 23 and the movable plate material 24, and the push-up bolt 33 is tightened until the head is separated from the lower surface of the movable plate material 23.

行なうことができる。Further, the end portion 25a of the rod 25 is connected to the plate material 2 of the holding device 21.
2. Even if it detaches from the movable plate 23, it will remain on the slope 35 of the guide plate 34 of the jig 30, so the end 25a of the rod 25 is slid on the slope 35 to remove the plate 22 and the movable plate 23. It is possible to move up to a certain point, and the return work can be performed relatively easily.
なお、この実施例では、復帰作業を迅速に行なうため、
常時、治具３０を保持装置２１に装着するようにしたが
、この常時装着の代わりに、必要に応じ、治具３０を保
持装置２１に適宜着脱することもできる。In addition, in this embodiment, in order to perform the recovery work quickly,
Although the jig 30 is always attached to the holding device 21, instead of being always attached, the jig 30 can be attached to and detached from the holding device 21 as needed.
