Problems solved by technology

However, the cost of the power storage device is higher than that of the arrival floor device during a power outage. In order to prevent the elderly from being stranded on high floors as described above, if the power storage device is installed separately for a plurality of numbered equipment, the cost will become very high.

no. 1 Embodiment approach

[0019] First, the first embodiment of the present invention will be described.

[0020] figure 1 It is a figure which shows the outline of the structure of the elevator of the 1st Embodiment of this invention. In addition, in the first embodiment, only two numbering devices are illustrated for description.

[0021] in figure 1 In the illustrated example, a is attached to the end of the symbol of the constituent element of the No. 1 elevator (No. 1 numbering device), and n is attached to the end of the symbol of the constituent element of the elevators after the No. 2 elevator (No. 2 numbering device). Hereinafter, in the case of a generic name, the description will be given with numbers omitting these characters.

[0022] Each numbered device of the elevator includes as a drive system: a commercial power source 1; a rectifier 2 that converts the AC voltage of the commercial power source 1 into a DC voltage; a smoothing capacitor 3 that smoothes the ripple of the DC voltage; and...

no. 2 Embodiment approach

[0073] Hereinafter, the second embodiment of the present invention will be described. In addition, in the elevator structure of the following embodiments, and figure 1 The description of the same part is shown.

[0074] Figure 4 It is a figure which shows the outline of the structure of the elevator of the 2nd Embodiment of this invention.

[0075] Such as Figure 4 As shown, in the elevator of the second embodiment of the present invention, compared with the first embodiment, the car 9 of each numbering device is provided with an announcement device 18 as a reporting unit connected to the control circuit 12.

[0076] The broadcasting device 18 of each numbering device has a built-in storage device for storing broadcasting sound information. In this storage device, voice information for notifying the passengers in the car 9 that the normal operation has been resumed and voice information for guidance at the time of arrival at the floor during a power outage are stored. The voic...

no. 3 Embodiment approach

[0084] Hereinafter, the third embodiment of the present invention will be described.

[0085] Figure 6 It is a figure which shows the outline of the structure of the elevator of the 3rd Embodiment of this invention.

[0086] Such as Figure 6 As shown, the elevator of the third embodiment of the present invention, compared with the first embodiment, includes one rescue operation circuit 19 connected to the group management control device 22 and the control circuit 12 of each numbered device.

[0087] The rescue operation circuit 19 instructs the control circuit 12 of the numbering device whose normal operation has resumed to perform call registration of the floor reached by the car 9 of the numbering device that has been operated at the time of power outage.

[0088] Figure 7 It is a flowchart showing an example of the control operation performed by the elevator of the third embodiment of the present invention.

[0089] In this embodiment, the processing of steps S1 to S3 descr...

Abstract

The invention provides a lift having a power circuit (2, 3, 4, 6, 12) respectively arranged for the plurality of numbering equipment and normally lifting the car (10) by commercial power supply; an electrical storage device (21) for storing electric energy; a power failure detecting device (14) for detecting the power failure of the commercial power supply; a first electric energy supply portion (41) for supplying the electric energy stored in the electrical storage device to the power circuit of the special numbering equipment when the power failure detecting device detects the power failure; a normally running restarting controlling portion (51) for normally running the car of the special numbering equipment when the first electric energy supply portion supplies; a second electric energy supply portion (42) for supplying the electric energy stored in the electrical storage device to the power circuit of the numbering equipment of the floor which the special numbering equipment does not arrive; a power failure running portion (13) for lifting the car of the special numbering equipment at the speed lower than the normal speed to arrive to the nearest floor when the second electric energy supply portion supplies.

Description

Technical field [0001] The present invention relates to an elevator having an operation function during a power outage. Background technique [0002] Conventionally, if a power outage occurs, the elevator car loses power, and the car brakes and stops urgently. Because of this situation, for example, there is a means to include a self-generating device in a building-side facility. However, because it requires a lot of cost to use this method, it is generally used instead of a self-generating device, and a floor-arrival device with a built-in storage battery is used. [0003] This floor-arrival device during a power outage is a device that operates on a battery during a power outage to make the car stopped due to a power outage run at a low speed to the nearest floor, and to rescue passengers from the car through this operation. This floor-arrival device at the time of a power outage is attached, for example, to each elevator. In addition, for example, as disclosed in Japanese Pate...
