Description

  The present invention relates to an elevator apparatus to which a fire fighting function is added to extinguish a fire in a building where an elevator is installed.

  In general, an elevator is installed in a building having a middle or high-rise building or higher. When a fire is detected in a building, etc., passengers in the elevator are evacuated and then moved to the bottom floor to stop secondary disasters.

  Regarding fire in an elevator pit, for example, a fire extinguishing device for a fire in an elevator pit has been proposed (see, for example, Patent Document 1). This is to cope with a pit fire by attaching a fire extinguisher to the lower part of the elevator car and injecting a fire extinguishing agent from an injection nozzle when the heat sensing part of the fire extinguisher main body senses heat.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same portions are denoted by the same reference numerals, and redundant description is omitted.

(First embodiment)
FIG. 1 is a schematic cross-sectional view showing a configuration example of an elevator apparatus according to an embodiment of the present invention. As shown in FIG. 1, an elevator has a hoisting machine 3 installed in a hoistway 2 in a building 1. A rope 7 is hung on the hoisting machine 3. One end of the rope 7 is attached to the car 4, and a counterweight 5 is suspended at the other end. The elevator car 4 is controlled to be able to stop at each landing 6.

  In the present embodiment, the reference floor of the building is a floor called a so-called main floor, and evacuation guidance is performed in an emergency. In addition, the lowest floor of the building is the lowest floor in the building and is the floor immediately after the pit floor of the hoistway 2. Further, the rescue floor is a floor where passengers get into the elevator in case of fire or the like. The evacuation floor refers to a floor from which passengers escape in the event of a fire or the like, and in many cases, the above-mentioned reference floor.

  As shown in FIG. 1, an opening 13 connected to the outside of the hoistway 2 is provided on the uppermost floor or the reference floor of the hoistway 2 of the building 1. At the lower part of the elevator car 4, a cylindrical member 9 for water supply for extinguishing the fire floor of the building 1, a connecting part 11 for connecting to a water discharge port of a fire engine outside the building, and the cylindrical member 9. Is stored in the storage box 8. The cylindrical member 9 is a so-called fire hose and is made of a material that can withstand water pressure during fire extinguishing. As for the diameter, 40 mm, 50 mm, and 65 mm are common. For example, it is possible to select a polyester fiber lined with a polyurethane resin and having a working pressure of 1.3 MPa and a diameter of 50 mm. The length is preferably substantially equal to the height of the hoistway 2. A part of the storage box 8 is formed with a fixed or rotary hose rack for hanging the tubular member 9.

  An injection port 12 is disposed on one end side of the cylindrical member 9. The injection port 12 is preferably a nozzle made of an aluminum alloy casting, for example. Or the spray outlet suitable for rod-shaped water discharge or direct water discharge may be sufficient.

  Since the cylindrical member 9, the connecting portion 11, and the driving device 10 are stored in the storage box 8, the elevator device can be discharged during a fire without being affected by the traveling of the elevator in cases other than a fire. .

  Drawing 2 is a mimetic diagram explaining the water discharge state using the elevator device at the time of a fire. As shown in FIG. 2, the cylindrical member 9 is deployed from the storage box 8 by the driving device 10 in the event of a fire. A connecting portion 11 attached to one end side of the tubular member 9 is connected to a water discharge port of a fire engine outside the building via the opening 13. The connecting operation of the connecting portion 11 is performed by a firefighter. It goes without saying that the firefighter may enter the pit from the opening 13 in connection operation depending on the shape or size of the opening 13. When the elevator moves to the fire floor 14, the landing door 18 is opened, and water is discharged to the fire floor 14 from the injection port 12 disposed on one end side of the tubular member 9.

  When the fire place is a place away from the elevator hall on the fire floor 14, the tubular member 9 is further deployed, and the fire outlet directs the injection port 12 to the fire at the fire site.

  FIG. 3 is a flowchart up to water discharge in the event of a fire. When a fire occurs, the elevator carrying the passenger from the rescue floor moves to the nearest safe floor and evacuates the passenger on the elevator (step S31). After evacuating passengers on the evacuation floor, the elevator moves to the lowest floor or the reference floor of the building 1 (step S32). When the elevator arrives at the lowest floor or the reference floor, the drive unit 10 installed in the storage box 8 below the car 4 is activated to connect the connecting portion 11 to be connected to the hose of the fire engine 15 from the storage box 8 to the hoistway. 2 (step S33).

The firefighter connects the water discharge hose 16 of the fire truck 15 and the connecting portion 11 from the outside of the hoistway 2 (step S34). By reciprocating the car 4 by one reciprocation in the hoistway 2 by remote operation, the cylindrical member 9 stored in the storage box 8 is taken out to the hoistway 2 (step S35). Needless to say, when the cylindrical member 9 is smoothly deployed from the storage box 8, one reciprocation of the car 4 can be omitted.

  Next, the car 4 is moved to the fire floor 14 (step S36). The elevator car 4 is stopped at a position where the car 4 is above the landing position, the injection port 12 can be seen from the hall 6, and the car door 17 and the hall door 18 are opened synchronously. And the landing door 18 is opened (step S37). Thereafter, water is discharged from the fire engine 15 and discharged toward the elevator hall 6 through the tubular member 9 (step S38).

According to the present embodiment, the firefighter can discharge water to the fire floor 14 by remote operation without moving to the fire floor 14, so that the firefighter can avoid danger and extinguish the fire, and quickly extinguish the fired building. (2nd embodiment)
Next, a second embodiment will be described. Fig.4 (a) is a schematic diagram which shows the lower part of the passenger car of the elevator apparatus which concerns on 2nd Embodiment, and FIG.4 (b) has shown the external monitor arrange | positioned outside a building.

  By adopting such a configuration, the person in charge of fire fighting activities can accurately find the fire source by the external monitor 22, so that the direction of the injection port 12 can be correctly determined. Therefore, fire fighting is performed safely and smoothly.

(Third embodiment)
Next, a third embodiment will be described. FIG. 5A is a schematic diagram showing the lower part of the elevator car of the elevator apparatus according to the third embodiment, and FIG. 5B shows an external monitor arranged outside the building. In the third embodiment, a thermal sensor 23 such as an infrared sensor is attached in the vicinity of the injection port 12 installed under the elevator car 4 in order to detect heat on the elevator landing door 18 side. ing. A signal from the thermal sensor 23 is transferred to the external monitor 22.

  By adopting such a configuration, the person in charge of fire fighting activities can accurately confirm the source of the fire with the external monitor 22, so that the direction of the injection port 12 can be correctly determined. Therefore, fire fighting is performed safely and smoothly.

(Fourth embodiment)
Next, a fourth embodiment will be described. FIG. 6 is a schematic cross-sectional view showing a main part of an elevator apparatus according to the fourth embodiment. As shown in FIG. 6, a water tank 24 and a tubular member 25 connected to the water tank 24 are installed on the ceiling of the hoistway 2 of the building 1. A cylindrical member 9 and a pump 28 for extinguishing a fire in the building 1 are stored in the storage box 8 at the lower part of the elevator car 4. The tubular member 9 is normally folded, and in a fire, the tubular member 9 is expanded by the driving device 10. An injection port 12 is attached to the front end side of the pump 28. The connecting portion 11 for connecting to the tubular member 25 connected to the water storage tank 24 is fixed by a guide 26 attached to the side surface of the car 4, avoiding the counterweight 5 in the hoistway 2. Therefore, in a case other than a fire, the elevator apparatus is not affected when the elevator travels and can discharge water in the event of a fire.

  Next, in such a configuration, water discharge using an elevator apparatus at the time of fire will be described. FIG. 7 is a schematic diagram for explaining a water discharge state using the elevator apparatus at the time of a fire. At the time of a fire, the elevator car 4 is landed on the fire floor 14, the tubular member 25 connected to the water storage tank 24 is connected to the connecting portion 11, and the tubular member 9 is developed by the driving device 10, Is discharged to the fire site.

  FIG. 8 is a flowchart up to water discharge in the event of a fire. When a fire occurs, the elevator carrying the passenger from the rescue floor moves to the nearest safe floor and evacuates the passenger on the elevator (step S81). After evacuating passengers on the evacuation floor, the elevator moves to the top floor of the building 1 (step S82). When the elevator arrives at the top floor, the drive device 10 installed in the storage box 8 under the car is activated, and the connecting portion 11 is taken out from the storage box 8 to the hoistway 2 (step S83).

  Next, the tubular member 25 connected to the water storage tank 24 and the connecting portion 11 are connected (step S84). The car 4 is moved to the fire floor 14 by remote control (step S85). Next, the car door 17 is opened and the landing door 18 is opened (step S86). Thereafter, the pump 28 is started, water is supplied from the water storage tank 24, and water is discharged in the direction of the elevator hall 6 through the tubular member 9 (step S87).

  According to the present embodiment, since the firefighter can discharge water to the fire floor 14 only by remote operation without moving to the fire floor 14, early fire extinguishing is possible.
