Description

  The present invention relates to an emergency rescue operation apparatus for an elevator that rescues a person left in an elevator hall during a fire after an earthquake.

  Conventionally, there has been proposed an evacuation operation of an elevator car when a fire occurs (see, for example, Patent Document 1). As soon as the fire alarms installed on each floor are activated, the passengers are immediately stopped driving, and the car stops only on the predetermined evacuation floor and the floor on which the fire alarm operates (hereinafter referred to as the fire floor). The evacuation operation is performed. Thereby, the person in a fire floor can be evacuated to an evacuation floor early, and can be rescued.

  On the other hand, when an earthquake occurs, the car is stopped at the nearest floor according to the elevator seismic design and construction guidelines, and then suspended. This is because it is determined that it is better not to move after that because there is a possibility that the building or the elevator equipment is damaged.

JP 58-52171 A (page 4-6)

  However, when an earthquake occurs, it is fully possible that a fire will occur after that, and early evacuation is required at that time. In particular, in hospitals and special elderly nursing facilities, it is difficult for people who have difficulty walking to evacuate using stairs, so the use of elevators is indispensable.

  Therefore, it is necessary to perform a rescue operation in the event of a fire after stopping the car on a predetermined floor by driving during an earthquake, but if the counterweight is off the rail due to the influence of the earthquake, for example, If you let it run, when the car passes the counterweight, the car may collide with the counterweight and cause damage.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an emergency rescue operation device for an elevator that can safely rescue a person left in the elevator hall during a fire after an earthquake. And

  The elevator rescue operation device for an elevator according to the present invention performs an earthquake operation that stops and stops the car on a predetermined floor based on the operation of the earthquake detector, and also operates the operation of the fire detector or the fire rescue operation switch. In the fire rescue operation apparatus of the elevator provided with the control means for performing the rescue operation based on the fire, the control means performs the fire rescue operation after stopping the car on the predetermined floor by the earthquake operation In this case, the fire rescue operation is performed on the floor where the cage does not pass the counterweight.

  This invention is based on the fact that when a fire is rescued during a fire after the car has been suspended on a predetermined floor by an earthquake operation, the rescue operation during a fire is performed on the floor in a range where the car is not mistaken for a counterweight. People who are left behind in the elevator hall during a later fire can be rescued safely.

  FIG. 1 is a hardware block diagram showing a configuration of an elevator fire rescue operation apparatus according to an embodiment of the present invention. The elevator rescue operation apparatus shown in FIG. 1 shows an example in which the control panel of the elevator is constituted by a microcomputer. The microcomputer 11 is controlled based on the input circuit 11a and the rescue operation program at the time of earthquake and fire. A CPU 11b as an operating control means, a memory 11c for storing a rescue operation program at the time of an earthquake and a fire, various data, and the like, and an output circuit 11d are provided.

  Here, the input circuit 11a is provided in the car destination button 1 installed in the car, the hall button 3 installed in the hall, the monitoring room or the landing on the evacuation floor, and immediately calls the car back to the evacuation floor. Rescue operation switch 5 in case of fire to respond to car calls and landing calls, seismic detector 6 which is provided in the machine room or hoistway and generates an output when it senses shaking of the building, car position to detect car position A signal from the detector 12 is input.

  In addition, the output circuit 11d is provided in the car or the hall, and is provided in the car 8 or the hall for the indicator 8 for displaying that an earthquake or a fire has occurred in the car or the elevator hall, and in the car or the elevator hall. Control to the alarm 9 for notifying the user that an earthquake or fire has occurred, the drive control device 10 for controlling the hoisting motor for running the car, or for controlling the door motor for opening and closing the door Send output.

  FIG. 2 is a functional block diagram of the microcomputer 11 shown in FIG. As shown in FIG. 2, the microcomputer 11 shown in FIG. 1 makes a car call registration means 2 for registering a car call when the car destination button 1 is operated and a hall call when the hall button 3 is operated. By using the hall call registration means 4 to be registered, the car call, the hall call, the fire rescue operation switch 5, the earthquake detector 6, and the car position detector 12, the car is run, stopped, the door is opened and closed, the indicator 8, the alarm. 9 and the control means 7 for controlling the drive control device 10. The control means 7 may include functions of the car call registration means 2 and the hall call registration means 4. The earthquake detector 6 outputs two types of detection levels to the control means 7, which are a first detection level, high gal (for example, 200 gal) and a second detection level, low gal (for example, 150 gal). Then, as will be described later, the control means 7 stops the elevator in the case of low gal, and after that, if high gal is not sensed, the fire rescue operation is enabled.

  FIG. 3 is a flowchart for explaining the control contents of the rescue operation at the time of earthquake and fire by the control means 7. The operation will be described below with reference to the flowchart shown in FIG. First, when an earthquake occurs and the earthquake detector 6 senses a shake (step S1), the control means 7 notifies the occurrence of the earthquake through the car 8 and the indicator 8 and the alarm 9 in the car, and the car is running. In that case, stop at the nearest floor (steps S2, S3). If it is stopped, the process proceeds to step S4 as it is and waits for 20 seconds to elapse after the door is opened (step S4).

  Next, if the earthquake sensor 6 senses high gal or if no fire has occurred, the door is closed and rested (steps S5 to S12). In this state, even if a predetermined time (for example, 30 minutes) elapses, the process ends if the fire rescue operation switch 5 is not turned ON (step S13 → end). On the other hand, if a fire occurs within the elapsed time and the manager turns on the rescue operation switch 5 at the time of fire, if the high gull is not sensed (when it is low gall), the indicator 8 in the car or the landing Then, the alarm 9 notifies the occurrence of a fire (steps S13 → S5, S6).

  Next, it shifts to the rescue operation at the time of the fire. At this time, if the car is a higher floor than the intermediate floor based on the detection signal from the car position detector 12, for example, a 4-story building, it is on the third to fourth floor When it is detected, the car call and the hall call on the upper floor (3rd to 4th floors) can be registered, and the evacuation floor is the uppermost floor (steps S7 → S8). Then, the car is slowed down and evacuation operation is performed in the upper floors (3 to 4 floors) (step S9). In this case, it is necessary to be able to evacuate from the 4th floor. For example, it is possible to evacuate through a slope, ladder car, heliport, passageway to the next building, etc.

  In step S7, when the car is on the lower floor, for example, the first or second floor, the car call and the landing call on the lower floor (1-2 floor) can be registered, and the evacuation floor is the first floor (the lowest floor or the entrance) Floor) (step S7 → S10). Then, the car is slowed down and evacuation operation is performed in the lower floor (step S11). That is, during a fire rescue operation after an earthquake, a fire rescue operation is performed on the floor in a range where the car is not mistaken for a counterweight.

  If there is no operation of the earthquake detector 6, normal operation is performed (step S1 → S14).

  After a car is suspended on the designated floor by driving during an earthquake, when performing a rescue operation in the event of a fire, by performing a rescue operation during a fire on a floor in a range where the cage does not pass the balance weight, A person who is left behind in the elevator hall can be rescued safely, and can be applied to an emergency rescue operation device for an elevator.

It is a hardware block diagram which shows the structure of the rescue operation apparatus at the time of the fire of the elevator which concerns on embodiment of this invention. It is a figure which shows the functional block of the microcomputer 11 of FIG. It is a flowchart explaining the control content of the rescue operation at the time of an earthquake and a fire by the control means 7 of FIG.
