Description

  Embodiments of the present invention relate to an emergency machine roomless elevator and an operation method of an emergency machine roomless elevator.

  Conventionally, a building exceeding a predetermined height is obliged to install an emergency elevator for use in firefighting operation in the event of a fire. This emergency elevator is normally used as a general elevator, but when a fire breaks out, the fire brigade uses it for emergency operation for fire fighting and rescue operations. Is provided. As one of the regulations, it was stipulated that an emergency elevator must have a machine room, but a machine roomless elevator that does not have a machine room was used as an emergency due to a partial revision of the Building Standard Law Enforcement Order. It became possible to apply as an elevator.

  When a machine roomless elevator is used as an emergency elevator, it is stipulated that the control panel must be installed at a position higher than the top floor level (the floor height of the top floor) in the hoistway. . This is to prevent water discharged for extinguishing the fire when the fire breaks out on the electronic parts of the control panel and failing to make emergency operation impossible.

<First Embodiment>
The configuration of the emergency machine roomless elevator according to the first embodiment of the present invention will be described with reference to FIG.

  The emergency machine roomless elevator 2 includes a hoisting machine 8 installed in a hoistway 6 (for example, near the top) of the building 4, a car 10 suspended from the hoisting machine 8, and a car 10. And a main control panel 16 connected via a tail cord 12 and a repeater 14. A central management room (also referred to as “disaster prevention center”) 18 is installed on the first floor, which is an evacuation floor. The monitoring panel 20 in the central management room 18 is provided with a monitoring display panel 22, an emergency call back button 24, an interphone 26, and a control panel changeover switch 28. The monitoring display panel 22 and the interphone 26 are devices originally installed in the monitoring panel 20 and are used for monitoring the building 4 and the car 10. The emergency recall button 24 is a button for recalling the car 10 to the first floor, which is an evacuation floor, in the event of a fire or the like. The control panel changeover switch 28 is a switch for switching between the main control panel 16 and an emergency control panel 30 described later by manual operation.

  The monitoring panel 20 in this embodiment is provided with an emergency control panel 30 that controls the operation of the car 10 in place of the main control panel 16 in the event of an emergency such as a fire. A switching device 32 is disposed in the vicinity of the monitoring panel 20. The emergency control panel 30 and the main control panel 16 are connected by a wiring 34 via a switching device 32. The emergency control panel 30 may be configured to be built in the monitoring panel 20. The switching device 32 may also be installed in the emergency control panel 30.

  In the car operation panel 36 installed in the car 10, a primary fire fighting operation switch (return switch) for starting emergency operation set in advance in the event of a fire and returning from emergency operation to normal operation. 38 and an intercom 40 are installed.

  In addition, an emergency call back button 42 is provided on the lowest floor (first floor), which is an evacuation floor, for returning the car 10 to the evacuation floor in an emergency.

  FIG. 2 shows the functional configuration of the main control panel 16 and the emergency control panel 30. The main control panel 16 includes an operation control unit 162 that controls the hoisting machine 8 during normal operation. The emergency control panel 30 includes an operation control unit 302 that controls the hoisting machine 8 during emergency operation. The operation control unit 162 and the operation control unit 302 are connected to each other via the switching device 32.

  A primary fire fighting operation signal, a return signal, and an emergency call return signal are input to the switching device 32. In addition, a control panel switching signal from the control panel switching switch 28 is input.

  The operation in the first embodiment will be described based on the flowchart of FIG. The switching device 32 monitors whether there is an emergency call back signal during normal operation (ST2) and whether there is a primary fire fighting operation signal (ST4, ST6). When the emergency call signal is input or the primary fire fighting operation signal is input (ST4YES, ST6YES), the switching device 32 executes a switching process from the main control panel 16 to the emergency control panel 30 (ST8). . Thereby, the emergency operation process by the emergency control panel 30 is executed from the normal operation by the main control unit 16.

  When the primary fire fighting operation signal is not input and the emergency call signal is not input (ST12NO, ST14NO), the control by the emergency control panel 30 is shifted to the control by the main control panel 16, and the normal operation is executed. (ST16).

  As described above, according to the first embodiment, when a fire or the like occurs during normal operation and the emergency call back buttons 24 and 44 are operated and an emergency call back signal is input, or the primary fire fighting operation in the car 10 is performed. When the switch 38 is operated and a primary fire fighting operation signal is input, the switching device 32 switches the control from the main control panel 16 to the emergency control panel 30 installed in the central management room 18 to control the operation of the car 10. I did it. For this reason, the emergency operation of the car 10 can be executed even when the main control panel 16 is submerged in the fire fighting operation. For this reason, there is no restriction on the installation location of the main control panel 16 installed in the hoistway 6 such as above the uppermost floor level of the hoistway 6. Further, since the emergency control panel 30 is installed in the central management room 18, it is not damaged by flooding or the like due to fire fighting activities. In addition, information can be exchanged between the manager in the central control room 18 and the worker (firefighter) in the car 10 through the intercoms 26, 40, etc., enabling efficient emergency operation processing. Become.

Second Embodiment
The emergency control panel 30 according to the second embodiment performs operation direction control when a fire occurs. That is, it is controlled to operate at a speed lower than the normal speed in the direction of the fire occurrence floor and to operate at a speed higher than the normal speed in a direction away from the fire occurrence floor. Here, assuming that the normal speed is 90 m / min, for example, 45 m / min or less is set as the low speed operation. Further, for example, high speed operation is performed at 120 m / min or more.

  As shown in the flowchart of FIG. 4, the emergency control panel 30 obtains information on the fire occurrence floor (ST22). The information on the fire occurrence floor is based on a manual input of a manager in the central management room 18 or a fire alarm signal inputted from the fire occurrence site. Next, the emergency control panel 30 confirms the current position of the car 10 (ST24). When the fire occurrence floor and the current position of the car are confirmed, the current car driving direction is detected (ST26). If the driving direction is the direction of the fire floor, the car is driven at a low speed (ST28). If the direction is away from the direction of fire, the car is driven at high speed (ST30).

  As described above, according to the second embodiment, the same effects as those of the first embodiment are achieved, and the vehicle is operated at a lower speed than the normal speed in the direction of the fire occurrence floor, and is higher than the normal speed in the direction away from the fire occurrence floor. Because it is controlled so that it can be operated at a speed, evacuation and fire fighting activities can be performed quickly and safely.

<Third Embodiment (Safety Device Separation Function)>
At the time of secondary fire fighting operation, it is a mode that gives top priority to prevention of confinement by separating safety devices having functions not essential for emergency operation.

  In the third embodiment, not all safety devices are disconnected in the event of a fire, but even if an abnormality occurs, the car 10 is operated while in contact with the firefighters in the car 10. Only the safety device that has stopped the operation or only the safety device that is suspected of occurrence of a failure or the like is sequentially disconnected. This makes it possible to drive the car while effectively using the safety device as much as possible.

  As safety devices around the elevator door, (1) Passenger detection devices such as photoelectric devices (multi-optical axis door safety), (2) Mechanical door safety (safety shoe), (3) Door short circuit (door mechanism, etc.) Safety device). These safety devices around the door do not interfere with the secondary fire-fighting operation and may be separated.

  Other safety devices include (4) a load detection device, (5) an emergency rescue exit switch, (6) a safety circuit for an emergency stop switch in a car, and (7) an earthquake detector. These safety devices are not separated at a time, but the order of separation is set in advance so that they are sequentially removed from unnecessary safety devices. The disconnecting operation can be performed manually by a firefighter in the car, but as shown in FIG. 5, the safety device for automatically disconnecting the safety device in the emergency control panel 30 is cut off. This is possible by installing the separation portion 304. That is, the safety device of the main control panel 16 is automatically disconnected by remote operation from the emergency control panel 30 according to a preset separation program in the safety device separation unit 304.

  As described above, according to the third embodiment, the same effects as those of the first and second embodiments can be obtained, safety devices unnecessary for emergency operation are separated, and emergency operation is efficiently performed while effectively utilizing the safety device. Can be executed automatically.

<Fourth embodiment>
≪Return process after fire fighting (safety check and main control panel 16 function check) ≫
When the fire extinguishing operation is completed and restored, it is necessary to return from the control by the emergency control panel 30 to the control by the main control panel 16. When the fire fighting operation is completed and the primary fire fighting operation switch (return switch) 38 is switched and a return signal is input to the switching device 32, the emergency control panel 30 executes a recovery process based on the return signal. In that case, it is not restored immediately to normal operation, but is restored after safety confirmation and function confirmation are completed.

  Therefore, as shown in FIG. 6, a recovery processing unit 306 is installed in the emergency control panel 30 in addition to the operation control unit 302 and the safety device separation unit 304.

  FIG. 7 is a flowchart showing a procedure of recovery processing in the recovery processing unit 306.

  In the recovery process, the operation of the suspended car is resumed. First, it is determined whether or not a predetermined time has elapsed after the end of the emergency operation (ST32, ST34). If the predetermined time has elapsed, it is checked whether a primary fire fighting operation signal or an emergency call signal is input (ST36). Further, it is checked whether or not the safety device has been operated (ST38). In addition, it is checked whether the car 10 is stopped other than the evacuation floor. If the primary fire fighting operation signal or emergency call signal is input, if the safety device is operating, or if the car 10 is stopped on the evacuation floor, the diagnostic operation is not started and the operation is stopped. The state is continued (ST42, ST44).

  Next, it is checked whether there is a user in the car 10 (ST46). When there is a user in the car 10, the operation suspension state is continued. When there is no user in the car 10, the diagnostic operation is started (ST46NO, ST48).

  In the diagnosis operation, first, a low-speed diagnosis operation is performed at a speed of 45 m / min or less (ST50). If no abnormality is detected in the low speed diagnosis operation, the high speed diagnosis operation is executed after the low speed diagnosis operation is completed (ST52 to ST56). If no abnormality is detected in the high-speed diagnosis operation, the door opening / closing diagnosis operation is executed after the high-speed diagnosis operation is completed (ST58 to ST62).

  If an abnormality is detected in the low-speed diagnosis operation, the high-speed diagnosis operation, or the door opening / closing diagnosis operation (ST52 YES, ST58 YES, ST64 YES), the diagnosis operation is stopped and the operation shifts to the operation stop state (ST66, ST68).

  If no abnormality is detected in the door opening / closing diagnostic operation, the diagnostic operation ends after the door opening / closing diagnostic operation ends (ST72), and a temporary recovery state is established (ST74).

  In step ST44, when the operation stop state is continued, in step ST68, when the diagnosis operation is stopped and the operation shifts to the operation stop state, this is notified to the monitoring panel 20 of the central control room, and a specialist engineer After being subjected to the inspection process, the main restoration is performed (ST76, ST78).

  As described above, according to the fourth embodiment, the same effects as those of the first to third embodiments can be obtained, and even if a return signal or the like is input, the normal operation is not immediately restored, and a diagnostic process such as a safety function is performed. Since recovery is performed after execution, reliable recovery processing becomes possible.

  If the main control panel 16 is defective as a result of the diagnosis process, the control panel changeover switch 28 switches to the emergency control panel 30 so that the emergency control panel 30 is used as a main control panel during normal operation. May be. If the main control panel 16 and the emergency control panel 30 have the same function, the main control panel 16 damaged by the fire extinguishing activity is removed and the emergency control panel 30 is installed in the hoistway 6. May be.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
