Description

  Embodiments described herein relate generally to an elevator with a floor adjustment function.

  Elevators usually have an automatic recovery operation function during an earthquake. This automatic restoration operation function at the time of an earthquake performs a diagnostic operation to check whether an abnormality caused by the earthquake has occurred in the elevator after the earthquake has occurred, and it is confirmed that no abnormality has occurred. This is a function to restart the elevator.

  Specifically, the above-described diagnostic operation confirms whether or not an abnormality caused by the earthquake has occurred in the elevator by executing the following processing.

  First, after an earthquake occurs, the elevator is operated at a low speed between the lowermost floor and the uppermost floor to execute a process for confirming whether or not an abnormality has occurred in the hoistway equipment. Subsequently, the elevator is stopped at each floor at the rated speed, and the door is opened and closed to execute a process for confirming whether or not an abnormality has occurred in the door.

  And if it is confirmed as a result of performing the above-mentioned diagnostic driving | operation that abnormality has not generate | occur | produced in an elevator, an elevator will be restarted by the automatic restoration operation function at the time of an earthquake. As a result, it is possible to restart the elevator even if the maintenance staff does not go to the site, and it is possible to shorten the time until the elevator is restarted.

  By the way, in addition to a “single deck elevator” composed of a single car, there is an elevator called an “elevator with a floor adjustment function (eg, a double deck elevator)”. This elevator with an inter-floor adjustment function is an elevator that can be transported in large quantities by constructing a car in at least two stages, and is mainly used as a vertical means of transportation in a building such as a skyscraper.

  Here, if the automatic restoration operation function at the time of an earthquake is installed in an elevator with a floor adjustment function, when each car is sequentially stopped on each floor during diagnostic operation, it will be stopped redundantly on the same floor, resulting in wasted time. Will take.

  The problem to be solved by the present invention is to provide an elevator with a floor adjustment function that can reduce the time required for diagnostic operation for automatic restoration and restore it as soon as possible.

  An elevator with a floor adjustment function according to an embodiment includes a car frame in which at least two car rooms are connected in the vertical direction, and the distance between the car rooms of the car frame can be adjusted. When the operation operation control means for controlling the operation operation of the vehicle and the operation operation control means are switched to the diagnosis operation for sequentially stopping the respective car rooms on each floor, the respective car rooms do not stop on the same floor. And a diagnostic operation means for controlling the operation of the car frame.

FIG. 5 is a diagram illustrating an example of an operation when an abnormality occurs in the car door of the elevator with a floor adjustment function according to the embodiment.

  Hereinafter, an embodiment will be described with reference to the drawings.

  Drawing 1 is a figure showing the composition of the elevator with a floor adjustment function concerning one embodiment. Here, a double deck elevator having two cabs (hereinafter, the upper tier is referred to as the upper cab and the lower tier is referred to as the lower cab) 2 and 3 will be described as an example.

  A main rope 13 is wound around the hoisting machine 11 via a deflecting sheave 12 or the like. By driving the hoisting machine 11, the car frame 1 moves up and down in the hoistway via the main rope 13. An upper car 2 and a lower car 3 are connected to the car frame 1 via ball screws 5a, 5b, 6a, 6b so as to be movable in the vertical direction. These ball screws 5a, 5b, 6a and 6b are supported by the upper beam 1a and the intermediate beam 7, and move the upper car 2 and the lower car 3 in the vertical direction by driving the motors 4a and 4b, respectively.

  Further, the car frame 1 is equipped with a floor adjustment control device 20 and a door control device (not shown). These devices are connected to an elevator control device 10 installed in a machine room or the like of a building via a tail cord 14 wired to a car lower duct 15.

  The floor adjustment control device 20 drives the motors 4 a and 4 b in accordance with instructions from the elevator control device 10 to adjust the distance between the upper car 2 and the lower car 3.

  The elevator control device 10 is a so-called “control panel” and performs overall control of the elevator such as drive control of the hoisting machine 11. The elevator control device 10 outputs, for example, a control operation signal or the like to the floor adjustment control device 20.

  The control operation signal is output when switching from normal operation to control operation, such as when an earthquake is detected by the earthquake detector 16.

  Such a signal is given to the floor adjustment control device 20 via the tail cord 14. The floor adjustment control device 20 includes a replaceable memory device 30 including, for example, an EEPROM, a memory card, or a USB memory.

  The memory device 30 is usually provided with an inter-story length table for the control destination floor, an operation speed table for the departure floor and the destination floor, and the like.

  As shown in FIG. 1, the elevator control device 10 further includes a diagnostic operation unit 10A.

  The diagnostic operation unit 10A controls the operation of the car frame 1 during the diagnostic operation that is executed based on the earthquake automatic recovery operation function that is mounted on the elevator.

  Here, before describing the detailed functions of the diagnostic operation unit 10A, the diagnostic operation will be described.

  The diagnostic operation is a driving operation that is executed to check whether an abnormality caused by the earthquake detected by the earthquake detector 16 has occurred in the elevator. Specifically, first, after an earthquake occurs, the elevator is operated at a low speed between the lowermost floor and the uppermost floor. Thereby, it can be confirmed whether abnormality has generate | occur | produced in the hoistway apparatus. Subsequently, when it is confirmed that no abnormality has occurred in the hoistway equipment, the elevator is stopped at each floor at the rated speed, and the door is opened and closed. Thereby, it is possible to confirm whether or not an abnormality has occurred in the door (hold door / car door). In other words, the diagnostic operation is an operation that is executed to confirm the abnormality of the hoistway equipment and the abnormality of the door caused by the earthquake. As a result of executing this diagnostic operation, if it is confirmed that no abnormality has occurred, the operation operation switched from the normal operation to the control operation based on the above-described control operation signal is switched again from the control operation to the normal operation. be able to.

  The diagnostic operation unit 10A has a function of controlling the operation of the car frame 1 during the aforementioned diagnostic operation.

  Specifically, when the diagnostic operation unit 10A sequentially stops the upper car 2 and the lower car 3 on each floor in order to confirm an abnormality of the door, the upper car 2 and the lower car 3 overlap on the same floor. The operation of the car frame 1 is controlled so as not to stop.

  Further, the diagnostic operation unit 10A instructs the floor adjustment control device 20 to perform the floor adjustment when the upper car 2 and the lower car 3 are sequentially stopped on each floor in order to check the door abnormality. .

  In the normal operation, the floor adjustment is performed when the car frame 1 approaches the destination floor and decelerates. In the diagnosis operation, the upper car 2 and the lower car 3 are sequentially stopped on each floor, that is, the upper car. Since the destination floors of the second car 3 and the lower car 3 are determined in advance, the inter-story adjustment is performed when the car frame 1 is accelerated.

  Further, when there is a non-stop floor that does not stop during normal operation, the diagnostic operation unit 10A skips the non-stop floor during the diagnosis operation and sequentially stops the upper car 2 and the lower car 3 on each floor. Controls the operation of

  Next, an example of the operation of the elevator with a floor adjustment function having the above-described configuration when an earthquake occurs will be described with reference to the flowchart of FIG.

  First, when an earthquake of a predetermined level or more is detected by the earthquake detector 16 (YES in step S1), the elevator control device 10 generates a control operation signal for switching from normal operation to control operation. Output for. When the floor adjustment control device 20 receives the control operation signal input from the elevator control device 10, it controls the operation of the car frame 1 so as to move the car frame 1 from the current position to the nearest floor. At this time, the floor adjustment control device 20 moves the car frame 1 to the nearest floor while adjusting the floor of the upper car 2 and the lower car 3 (step S2).

  After the process of step S2, the passengers who are in the upper car 2 and the lower car 3 get off to the nearest floors.

  Subsequently, the elevator control device 10 determines whether or not a predetermined time has elapsed since the occurrence of the earthquake (step S3).

  If the predetermined time has elapsed (YES in step S3), the diagnostic operation unit 10A included in the elevator control device 10 performs a diagnostic operation. Specifically, first, the diagnostic operation unit 10A performs the operation of the car frame 1 so as to move the car frame 1 from the nearest floor moved by the process of step S2 described above to the lowest floor (or the top floor). Control (step S4).

  Subsequently, the diagnostic operation unit 10A operates the car frame 1 at a low speed so as to reciprocate at least once between the lowermost floor and the uppermost floor (step S5). Thereby, it is confirmed whether or not an abnormality has occurred in the hoistway device.

  Next, as a result of the processing in step S5, the diagnostic operation unit 10A determines whether or not an abnormality has occurred in the hoistway device (step S6). If a device abnormality has occurred (YES in step S6), the diagnostic operation unit 10A notifies the maintenance staff or operator resident in the remote monitoring center or the like that an abnormality has occurred in the hoistway device, The diagnostic operation in the elevator with the floor adjustment function is terminated.

  When no device abnormality has occurred (NO in step S6), the diagnostic operation unit 10A sequentially stops the upper car 2 and the lower car 3 on each floor, and opens and closes the door. At this time, the diagnostic operation unit 10A controls the operation of the car frame 1 so that the upper car 2 and the lower car 3 do not stop on the same floor, and sequentially stops the upper car 2 and the lower car 3 on each floor. (Step S7).

  Subsequently, as a result of the process in step S7, the diagnostic operation unit 10A determines whether or not an abnormality has occurred in the door (hold door / car door) (step S8). If a door abnormality has occurred (YES in step S8), the diagnostic operation unit 10A notifies the maintenance staff or operator resident in the remote monitoring center or the like that a door abnormality has occurred, and End diagnostic operation in the elevator with adjustment function.

  When the door abnormality has not occurred (NO in step S8), the diagnostic operation unit 10A switches the operation of the car frame 1 to the normal operation (step S9), and terminates the operation in the elevator with the floor adjustment function.

  When there is a non-stop floor, the diagnostic operation unit 10A controls the operation of the car frame 1 so that the non-stop floor is skipped and the upper car 2 and the lower car 3 are sequentially stopped on each floor.

  According to the embodiment described above, by the configuration including the diagnostic operation unit 10A capable of controlling the car frame 1 so that the upper car 2 and the lower car 3 do not stop on the same floor at the time of the diagnostic operation, The time required for diagnostic operation for automatic restoration can be shortened and the elevator can be restored as soon as possible.

  Here, the details of the above-described effects will be described with reference to FIGS.
