価になるという問題点もあった。In the conventional crane type linear motor elevator constructed as described above, since the counterweight 4 is moved up and down by the linear motor 5, it is possible to move up and down as compared with a hoisting machine. Although it is not necessary to provide the machine room 6 at the top of the road, the degree of freedom in the installation position of the machine room 6 is increased, but if the rescue operation device 8 during a power failure is used, the machine room 6 needs to be widened because the number of boards is increased. There was a problem. Further, the power source of the rescue operation device 8 during a power failure is generally the storage battery 13, but the storage battery 13 generates hydrogen (H 2 ) and oxygen (O 2 ) gas in proportion to the overcharge amount when charging. Since this gas becomes bubbles and stays between the electrodes of the storage battery 13, the effective contact area between the electrolytic solution and the electrodes decreases, and the apparent capacity of the storage battery 13 decreases.
Therefore, there is also a problem that rescue operation of the elevator at the time of power failure may be impossible. Furthermore, when the amount of overcharge increases, the generated gas goes out of the storage battery 13,
There is also a problem that it is necessary to provide a ventilation device 9 and the like in the machine room 6 in order to avoid an explosion due to hydrogen gas. Further, there is also a problem that the whole system becomes expensive because it is necessary to provide the power failure control cable 11 between the power failure rescue operation device 8 and the linear motor 5.

自由度が増している。In the figure, a power failure rescue operation device 8 similar to the conventional one is mounted on a counterweight 4 which is an elevating body.
As a result, the machine room 6 is narrowed by the power-saving rescue operation device 8 as compared with the conventional example, and the degree of freedom in its layout is increased.

行われ、エレベーターの安全性及び信頼性が向上する。In the linear motor elevator as described above, the storage battery 13 of the rescue operation device 8 during a power failure vibrates as the counterweight 4 moves up and down, and the air bubbles accumulated between the electrodes of the storage battery 13 being charged are removed. It This vibration is generated during each operation during the operation with the normal power source, and thus such removal of bubbles is repeated. Therefore, the apparent decrease in the capacity of the storage battery is prevented, the rescue operation at the time of power failure is more reliably performed, and the safety and reliability of the elevator are improved.

済的であり全体が安価になる。Further, by mounting the rescue operation device 8 at the time of power failure on the counterweight 4, the storage battery 13 is arranged in the hoistway, and the space volume around the storage battery 13 is larger than that in the machine room 6. The space around the storage battery 13 is enlarged, and the space around the storage battery 13 is spread over the entire building by opening and closing the hall doors.
The hydrogen gas (H 2 ) generated in 1 is sufficiently diffused. Therefore, the increase of the hydrogen gas concentration is prevented, and the ventilator 9 which is conventionally required can be omitted. Furthermore, by mounting the rescue operation device 8 at the time of power failure on the counterweight 4, the control cable 11 at the time of power failure can be omitted, so that it is extremely economical and the overall cost is low.

と同重量だけ軽くなっており経済的である。Generally, in a slip-type elevator, the counterweight side weight is set so as to be in balance with the car side weight when 45 to 50% of the rated load capacity is loaded on the car 3. Therefore, in the case of the conventional slip-line type linear motor elevator, although it depends on the weight of the linear motor 5, a considerable amount of the counterweight 4 is required. However, in the slippery linear motor elevator of the above-described embodiment, the weight of the counterweight 4 is larger than that of the conventional example in the rescue operation device 8 during a power failure.
It is the same weight as and is economical.

It suffices to mount the emergency rescue operation device 8 on the car 3,
The invention of claim 1 can be applied. Further, although the rope type (slave type) linear motor elevator is shown in the above embodiment, the invention of claim 1 can be applied to a low press linear motor elevator.

This has the effect of improving the flexibility of the layout of the machine room. In addition, since vibration is applied to the storage battery of the rescue operation device during a power failure, it is possible to prevent bubbles from accumulating between the electrodes of the storage battery, which can prevent an apparent decrease in the capacity of the storage battery. The rescue operation can be performed more reliably and the safety and reliability can be improved. Furthermore, since the space around the storage battery becomes wider, hydrogen gas is diffused,
It is also possible to omit the hydrogen gas countermeasure when charging the storage battery, and to omit the control cable during a power failure, and to reduce the cost as a whole.
