Abstract

PROBLEM TO BE SOLVED: To eliminate large swinging of a speed governor rope during earthquakes so as to prevent damage to a hoistway device disposed in a hoistway by suppressing a weight housed inside from being moved upward from its specified position with a stopper penetrating a connecting bar for connecting the weight to the lower end of the same in the upper plate of a box fixed on a hoistway floor. SOLUTION: A connecting bar 9a for suspending a weight 9 housed in a box-like stopper 20 fixed on a hoistway floor is put through a through-hole 20b created in the upper plate 20a of the stopper 20 and having a size for the penetration of the connecting bar 9a with play. Thus, when a tension sheave 8 is lifted, since the weight 9 is lifted more than a fixed height by the upper plate 20a, even if a speed governor rope 6 is largely swung by earthquakes, an attaching base 11 is prevented from being disconnected from a guide rail 10. Thus, the swing of the speed governor 6 is prevented from increasing more than a fixed size and damage of a hoistway device in the hoistway is prevented.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a side view showing a part of a cross section of an elevator according to the present invention. The same or corresponding parts as those of the conventional elevator shown in FIGS.
The description is omitted. In FIG. 1, the mounting base 11 is fixed to the guide rail 10 by sandwiching the guide rail 10 between a plate-shaped main body 11a and a conventional hook (not shown) which are the same as in the related art, and fastening the bolts 11c therethrough. ing. One end of the arm 12 is rotatably connected to the mounting base 11 by a shaft 12a, and can swing up and down. The tensioning wheel 8 is rotatably connected to a support shaft 8 a provided at the other end of the arm 12. The weight 9 is connected to and suspended from a lower end of a connecting rod 9a rotatably connected to the support shaft 8a.

The weight 9 is housed in a box-shaped stopper 20 fixed to the hoistway floor. The connecting rod 9 a hanging the weight 9 passes through a through hole 20 b formed in the upper plate 20 a of the stopper 20. Through hole 20b
Is sized to allow the connecting rod 9a to play freely. When the tensioner 8 is lifted upward, the weight 9 abuts on the upper plate 20a of the stopper 20. Other configurations are shown in FIGS.
Is the same as the conventional elevator shown in FIG.

In an elevator having such a configuration,
When the tensioner 8 is lifted upward, the weight 9 is
It will not be raised above a certain height by being blocked by a. Therefore, even if the governor rope 6 is greatly shaken by the earthquake, the mounting base 11 does not come off from the guide rail 10. Thereby, the swing of the governor rope 6 does not become larger than a certain value, and the hoistway equipment 13 in the hoistway 1 is not broken.

Embodiment 2 FIG. 2 is a side view, partly in section, showing another example of the elevator of the present invention. 2, in the present embodiment, a plate-shaped receiving plate 21 is provided in place of the weight 9 of the first embodiment. The receiving plate 21 is connected to the lower end of the connecting rod 9a and is housed in a box-shaped stopper 22 fixed to the hoistway floor. The connecting rod 9a passes through a through hole 22b formed in the upper plate 22a of the stopper 22. The stopper 22 has a thin wall and is not robust as compared with the stopper 20 of the first embodiment. Stopper 2
Inside 2, a spring 23, which is an elastic body, is disposed between the receiving plate 21 and the elevating road floor. The spring 23 has one end connected to the receiving plate 2.
1 and the other end is fixed to the ascending and descending floor, and extends between them. The spring 23 applies a constant tension to the governor rope 6 by its contracting force. Other configurations are the same as those of the first embodiment.

When the tension sheave 8 is lifted upward, the receiving plate 21 is blocked by the upper plate 22a of the stopper 22, so that the receiving plate 21 is not lifted above a certain height. And the spring 23
When the tensioner 8 is lifted upward, the receiving plate 21 is
A spring having an appropriate hardness is used so as not to collide with 2a.

In an elevator having such a configuration,
When the tension pulley 8 is pulled upward, the force of the spring 23 to contract gradually increases, so that the receiving plate 21 does not collide with the upper plate 22a of the stopper 22. Therefore, it is not necessary to further increase the strength of the stopper 22, and the cost can be reduced.

Embodiment 3 FIG. FIG. 3 is a side view, partly in section, showing another example of the elevator of the present invention. In FIG. 3, the receiving plate 21 is connected to the lower end of the connecting rod 9a and is housed in a box-shaped stopper 25 fixed to the hoistway floor. The connecting rod 9a penetrates a through hole 25b formed in the upper plate 25a of the stopper 25 as in the second embodiment. The spring 24, which is an elastic body, is
5 is contracted between the upper plate 25a and the receiving plate 21. The spring 24 extends through the connecting rod 9a and the upper plate 25a and the receiving plate 2
1, but not fixed to both. The spring 24 applies a constant tension to the governor rope 6 by its extending force. Other configurations are the same as those of the second embodiment.

In the elevator having such a configuration,
Since there is no need to fix the spring 24 to the receiving plate 21 or the upper plate 25a, the spring 24 can be easily installed as compared with the second embodiment. In addition, costs can be reduced.

Embodiment 4 FIG. 4 is a side view, partly in section, showing another example of the elevator of the present invention. In this embodiment, a pulley switch 27 as a first detection switch is provided inside the stopper 25 in FIG. The receiving plate 21 moves up and down by a certain width inside the stopper 25 when the elevator is operating normally. Tension switch 27 is provided at a predetermined position above the upper limit of the normal operation.

When the receiving plate 21 moves upward, the tension switch 27 detects the position of the receiving plate 21 and turns on. The detection signal of the pullover switch 27 is sent to the control unit 30 of the elevator. Other configurations are the same as those of the third embodiment. When the elevator control unit 30 receives this signal, the elevator car 30
Stop the operation of. When the operation of the car 2 stops, the movement of the counterweight 14 suspended on the opposite side also stops. The control unit 30 constitutes first control means for stopping the operation of the car 2 based on the detection signal of the detection switch 27.

In an elevator having such a configuration,
When the receiving plate 21 moves above the upper limit of the normal operation, that is, when the governor rope 6 largely shakes due to the earthquake, the sway switch 27 detects this swing. Then, the elevation of the car 2 and the counterweight 14 is stopped. Therefore, even if the counterweight 14 deviates from the counterweight guide rail due to the earthquake, it is possible to prevent an accident in which the car 2 and the counterweight 14 collide, and to prevent the counterweight 14 from damaging the hoistway equipment 13. Can be reduced.

Embodiment 5 FIG. FIG. 5 is a schematic diagram of a control unit showing another example of the elevator of the present invention. This embodiment is the same as Embodiment 4 in the configuration of the elevator shown in FIG. That is, when the receiving plate 21 moves upward, the tension switch 27 detects the position.
Then, a detection signal of the pulley switch 27 is input to the control unit 40 as a pulley signal 31. When the overhaul signal 31 is input, the CPU 32 outputs a stop command 33 to the car 2. Then, the operation of the car 2 is stopped. The above is the same as the fourth embodiment.

However, in the present embodiment,
When the tension switch 27 is turned off and the detection signal changes from presence to absence, the return timer 34 starts counting. Then, after the return timer 34 counts a predetermined number, the CPU 32 checks whether or not the car call signal 35 is present. If the car call signal 35 is present, the CPU 32 outputs the slow speed signal 36 to the corresponding car 2 and Slowly drive to the next floor. That is, if a predetermined time has elapsed after the tension switch 27 has been turned off, it is determined that the earthquake has been shaken. If a passenger is in the car 2 at that time, the passenger is allowed to travel to the nearest floor at a very low speed, and To release. The control unit 40 has a return timer 18, and when the return timer 18 counts a predetermined number, confirms the presence or absence of the car call signal 35, and if the car call signal 35 is present, the corresponding car is slowed down. It constitutes second control means for traveling to the nearest floor by traveling.

In an elevator having such a configuration,
When the governor rope 6 is largely shaken by the earthquake, the shake is detected by the tension switch 27, and the operation of the car 2 is stopped. Thereafter, when the shaking of the earthquake has subsided, if there is a mushroom call signal, that is, if a passenger is on the car 2, the car 2 is run at a very low speed to the nearest floor to release the passenger. Therefore, passengers are not left in the car 2.

Embodiment 6 FIG. FIG. 6 is a side view, partly in section, showing another example of the elevator of the present invention. In the present embodiment, a drop-off switch 38 as a second detection switch is provided below the stopper 25. The drop-off switch 38 is provided adjacent to the hoistway floor, and
Is removed from the connecting rod 9a and falls below the stopper 25, this is detected. The detection signal of the dropout switch 38 is transmitted to the control unit 50. When receiving the detection signal, the control unit 50 stops the operation of the car 2. Other configurations are the same as those of the fourth embodiment. Control unit 50
Constitutes third control means for stopping the operation of the car 2 based on the detection signal of the drop-off switch 38 which is the second detection switch.

If the governor rope 6 is greatly shaken by the earthquake and the force causes the receiving plate 21 to be disengaged from the connecting rod 9a, it is dangerous to continue the operation of the car 2 as it is. In the elevator according to the present embodiment, when the receiving plate 21 comes off the connecting rod 9a, the operation of the car 2 is stopped. Therefore, the tremor of the earthquake is very large.
Can be secured even when the vehicle is disengaged from the connecting rod 9a.

The present embodiment can be applied to the case where a spring is extended between the receiving plate and the elevating subgrade as in the second embodiment. In this case, the dropout switch 38 is
What is necessary is just to provide in the predetermined position located when 1 comes off from the connection rod 9a.
