Figures 3 and 4 are, for example, Utility Model Opening Showa 53-20767.
This figure shows a conventional elevator safety device disclosed in the publication. In the figure, 1 is a car, 2 is a guide shaft guided by a guide rail 3 set up in the hoistway, and 4 is the bottom of the car 1. 5 is a hydraulic jack installed on a jack stand 6 installed at the bottom of the hoistway, and the plunger 7
A sheave 8 is supported on the head. Reference numeral 9 denotes a main rope that is wound around the sheave 8. One end of this main rope 9 is connected to a rope stopper 10 attached to the jack stand 6, and the other end is connected to the above-mentioned rope stopper beam 4 with a spring 11 interposed therebetween. It is connected to the supported rope stopper rod 12. 13 is a switch operating plate provided on the rope tie rod 12, and 14 is a main rope slack detection switch provided on the rope tie beam 4.

れにより主索９が緩んだことが検出される。 Next, the operation will be explained. When the main rope 9 becomes loose, the rope stopper 12 moves downward due to its own weight and the weight of the main rope, so the switch operating plate 13 attached to the rope stopper 12 also moves downward and comes into contact with the slack detection switch 14. Then, the switch 14 is operated, thereby detecting that the main rope 9 has become loose.

Since the conventional main rope slack detection device is configured as described above, the through hole 4a of the rope tie rod 12 of the rope tie beam 4 is opened and closed by the rope tie rod 12 as the car 1 moves up and down.
Since the angle of the rope changes, a large hole is made so that the rope anchoring rod and the rope anchoring beam come into contact and bending stress due to the tension of the main rope 9 is not generated in the rope anchoring rod 12. Therefore, when the main rope 9 becomes loose, the rope stopper 12
Due to the bending and inclination of the main rope 9, the main cable 9 falls back and forth and left and right by the allowance between the hole 4a and the rod, causing the switch operation plate 13 and the switch 14 to be misaligned and no longer come into contact with each other. However, if the switch operating plate 13 is made larger in order to prevent the above-mentioned problem, there arises a problem that the switch operating plate comes into contact with another rope stopper provided adjacently while the car is being raised or lowered.

置を得ることを目的とする。 This invention was made in order to solve the above-mentioned problems, and even if the main rope becomes loose and the rope stopper bar moves downward, it prevents the rope from falling down, thereby adjusting the position of the switch operating plate and the switch. The object of the present invention is to obtain a main rope slack detection device that does not cause slippage.

In this invention, in order to achieve the above object, a hydraulic jack is installed on a jack stand installed in an elevator hoistway along the hoistway, and the head of the hydraulic jack is supported via a plunger that can be raised and lowered. The main rope is wound around a sheave wheel, one end of which is connected to a jack stand, and the other end is connected to a rope rod supported by a spring on the rope support beam of the car, and the rope is connected to the rope support beam. In a main rope slack detection device for a hydraulic elevator, which is equipped with a main rope slack detection switch on the top and a substantially circular switch operation plate on a rope stopper near the switch, the rope stopper is connected to the rope stopper when the large diameter slack of the rope stopper beam is removed. It is characterized in that it is configured to be inserted into the fitting hole and held therein, and also to prevent the rope stopper rod to which the switch operating plate is attached from falling down by passing the rope stopper rod to which the switch operating plate is attached through the insertion guide hole of the guide plate attached to the rope stopper beam. That is.

とができる。 The main rope slack detection device of the present invention is constructed as described above, and when the main rope 9 becomes slack, the switch operation plate 13 moves downward together with the rope stopper bar 12. At this time, even if the rope stopper rod 12 tries to fall down due to bending of the main rope 9, etc., the fall is restricted to a certain angle by the insertion guide hole 15a of the guide plate 15. Therefore, in advance, the rope stopper 12
If the size of the switch operation plate 13 is determined so that the switch 14 operates when the main rope falls down at the maximum angle, the slack of the main rope 9 can be reliably detected without the switch operation part 13 and the switch 14 being misaligned. be able to.

As described above, according to the present invention, by providing the guide plate on the rope tie beam to restrict the fall of the rope tie rod, when the main rope becomes loose, the switch operation plate and the switch do not shift in position. Looseness of cables can be detected reliably. Further, since the size of the switch operating plate is determined to be an appropriate size, there is an effect that the switch operating plate and the rope stopper rod do not come into contact with each other during raising and lowering of the car.
