In FIG. 1, a blocking member for blocking the counterclockwise rotation in a predetermined position, (16) is an operating piece that constitutes the detector-side end of the transmission arm (11), and the middle part is pivoted to the transmission arm (11). As a result, the coupling plate (9) side abuts against the lower surface of the transmission arm (11) to prevent the clockwise rotation in FIG. (1

A safety mechanism consisting of a bolt screwed into 1) and a push spring fitted between the bolt and the actuating piece (16) and the head of the bolt, and (18) is the pivot base (10). And an operation piece that is disposed so as to face the distal end portion of the operation piece (16) and that prevents displacement of the operation piece (16) due to clockwise rotation of the transmission arm (11) in FIG. 1 at a predetermined position. It is a deterrent.

検、修復の作業が減少する。In the elevator main rope device constructed as described above, the actuating piece (16) is pressed against the transmission arm (11) by the pushing spring of the safety mechanism (17). As a result, the operating piece (16) is held in a straight line with respect to the transmission arm (11) as shown in FIG. When the elastic body (7) is compressed by the overload of the car (2), the transmission arm (11) rotates counterclockwise in FIG. 1 and presses the first detector (14). .. Also,
When the elastic body (7) is overextended due to an abnormality such as breakage or loosening of the main rope (5), the transmission arm (11) is rotated clockwise in FIG. 1 and pressed by the second detector (15). To be done. Then, after the operation of the second detector (15), the transmission arm (11) further rotates,
The operating piece (16) is supported by the operating piece blocker (18). As a result, the operating piece (16) is refracted against the relatively small pressing force of the pressing spring of the safety mechanism (17), that is, the operating piece (16) is displaced relative to the transmission arm (11) and the state shown in FIG. Becomes Therefore,
The transmission arm (11) eliminates the support of large load when the elastic body (7) is over-extended, and is deformed to the lower part of the pivot stand (10), detector, etc.,
Damage will not occur, and inspection and repair work after the occurrence of an abnormality in the main rope (5) will be reduced.

後の点検、修復作業を簡略化する効果がある。As described above, according to the present invention, the elastic member supporting the main rope is engaged with one end of the elastic member, and the one end of the transmission arm is rotatably operated. An operating piece for pressing the device is provided, and the operating piece is always held at a predetermined position with respect to the transmission arm, and due to excessive displacement of the elastic body, the operating piece is supported by the operating piece blocker arranged on the fixed body. In this case, a safety mechanism that displaces the actuating piece relative to the transmission arm is provided, which eliminates the load support by the transmission arm when the elastic body is over-displaced, and inspects after the occurrence of an abnormality in the main rope. This has the effect of simplifying the repair work.
