あった。SUMMARY OF THE INVENTION In the conventional elevator main index stop device as described above, passengers get on and off between cars and landings at normal times, dynamic load changes at the time of car acceleration and deceleration, and The load fluctuates due to, for example, a passenger jumping up mischief within the vehicle. The characteristics of the cleat spring 5 are set so that the slack detector 10 does not operate due to the expansion and contraction of the cleat spring 5 due to these load fluctuations, and the slack detector 10 operates reliably due to an abnormality such as the slack of the main rope 4. Need to be set. For this reason, if the spring constant of the cleat spring 5 is set to a small value, the loosening of the main rope 4 can be reliably detected.
There has been a problem that erroneous detection of the operation of the looseness detector 10 occurs due to a change in the load of the car predicted during normal operation.

といった誤差検出が増加することになる。[0007] If the spring constant of the cleat spring 5 is reduced, the amount of sinking of the car at the time of passenger getting on and off increases. For this reason, it is necessary to keep the sinking amount of the car within a predetermined value, which limits the reduction of the spring constant of the cleat spring 5. Further, in an elevator having a large load capacity and a heavy car weight, the number of main ropes 4 is generally large. Accordingly, since the spring constant of the cleat spring 5 increases, the amount of deflection of the cleat spring 5 decreases. When the amount of bending of the rope retaining spring 5 decreases, the displacement from the amount of bending in a normal state to the amount of bending in a state of loose rope becomes very small, and detection becomes impossible. In addition, since the displacement is very small, the displacement required to absorb the setting error of the slack detector cannot be secured, and the error of detection that the rope is detected as loose even in a normal state due to the setting error increases. .

れる。Although not shown in the drawing, in the case of a winding drum type elevator in which a counterweight is provided to reduce the size of the hoisting machine, the load caused by the car is small, so that the deflection of the cleat spring 5 during normal operation is reduced. Since the amount is small, false detection of the looseness detector 10 increases. In general, since a plurality of main ropes 4 are provided, in the case of a device configuration in which a slack detector 10 is provided for each main rope 4, the slack detector 10 for each main rope 4 is provided.
In order to secure the installation space, the degree of freedom of design is impaired.

However, since the amount of elongation of each main rope 4 differs due to aging, the looseness detector 10 of the main rope 4 having large elongation may operate even if there is no looseness, and erroneous detection may occur.

止め棒33に伝動される。The slack detector 37 operates by the protrusion of the rope stopper bar 33. Through the operation of the slack detector 37, the elevator is controlled when it is abnormal. The amount of protrusion of the cleat bar 33 when the rope retaining spring 5 is abnormally extended is increased by the enlarged transmission mechanism 28, that is, the rope wrapping mechanism by the 2: 1 roping in which the pulley 30 and the transmission cable 32 are arranged.
The amount of operation due to the expansion and contraction of the rope retaining spring 5 is doubled and transmitted to the cleat bar 33.

The amount of deflection of the cleat spring 5 due to the load fluctuation of the car predicted during normal operation is as follows.
It is enlarged and transmitted twice.

Since the amount of deflection of the cleat spring 5 for detecting the looseness of the main rope 4 is substantially doubled, the looseness detector 37
Operating accuracy is increased. Therefore, even if the spring constant of the cleat spring 5 is set to a small value, the looseness of the main rope 4 can be reliably detected, and erroneous detection in which the looseness detector 37 operates due to a predicted car load change during normal operation is generated. Can be prevented.

In this case, the characteristics of the cleat spring 5 can be easily set so that the looseness detector 37 operates reliably due to the abnormality. Therefore, it is possible to obtain a main index stopping device for an elevator, which can reduce the malfunction of the slackness detector 37 and can operate the elevator with high reliability.

る。Thus, when the main rope is abnormally elongated or loosened, the retaining spring is extended, the retaining member is abnormally lowered, and the operating plate is also lowered. Then, the slack detector operates via the operation of the expansion transmission mechanism due to the lowering of the operation plate. That is, the slack detector operates due to the abnormal lowering of the detent device due to the slack of the main rope or the like, that is, the amount of extension of the cleat spring is expanded and transmitted by the expansion transmission mechanism. As a result, the slack detector does not operate due to the expansion and contraction of the cleat spring due to the load fluctuation of the car predicted during normal operation,
The characteristics of the cleat spring can be easily set so that the slack detector operates reliably due to an abnormality such as slack of the main rope. Therefore, there is an effect that the malfunction of the slack detector is reduced and the operation of the elevator with high reliability is realized.

おける設計の自由度を向上する効果がある。Thus, when the main rope is abnormally elongated or loosened, the rope retaining spring is extended, the retaining member is abnormally lowered, and the operating plate is also lowered. Then, the slack detector operates via the operation of the expansion transmission mechanism due to the lowering of the operation plate. That is, the slack detector operates due to the abnormal lowering of the detent device due to the slack of the main rope or the like, that is, the amount of extension of the cleat spring is expanded and transmitted by the expansion transmission mechanism. This allows the slack detector not to operate due to the expansion and contraction of the rope retaining spring due to fluctuations in the car load predicted during normal operation, and the rope detector to operate reliably due to an abnormality such as loose main ropes. The characteristics of the stop spring can be easily set. Therefore, there is an effect that the malfunction of the slack detector is reduced and the operation of the elevator with high reliability is realized. Further, since the load detector connected to the transmission means is provided, the load detection function in the car and the abnormality detection function of the main rope can be easily arranged in a small space, and the effect of improving the design flexibility in a small car or the like can be improved. There is.
