Description

  The present invention relates to an elevator apparatus and a confinement rescue operation method that can efficiently and safely perform a confinement rescue operation (adjacent elevator rescue function) in an elevator apparatus.

  In particular, in a high-rise elevator, if the elevator stops for some reason while traveling near a skip floor without a hatch door and the restart becomes impossible, an elevator confinement occurs. In the confinement occurrence near the skip floor where there is no hatch door, a confinement rescue operation (adjacent elevator rescue function) is executed as a function for rescue.

  The confinement rescue operation (adjacent elevator rescue function) is to rescue an elevator car adjacent to a stopped elevator car by approaching the failure stop position and transferring passengers between the elevator cars. At this time, if there is a building beam in the vicinity of the failure stop position, it is not possible to transfer, so the elevator car that has stopped will be moved in the height direction to transfer at a height position without building beams. Considering passengers' anxiety, it is necessary to execute in a short time and safely.

  With respect to this point, in Patent Document 1, before entering these states, it is determined whether the automatic rescue operation of confinement by the car (adjacent elevator rescue function) can be used, and is displayed in advance, which is a waste of the automatic rescue operation. It is proposed to eliminate unnecessary time. Specifically, in Patent Document 1, it is possible to display whether or not a rescue car can be rescued or to rescue a stopped car based on the presence or absence of an obstacle such as a building beam at the stop position of the car that has been stopped and trapped. A technique for displaying the distance traveled to a position has been proposed, and the time required for rescue is shortened by informing in advance of a rescue method other than the rescue method using an adjacent car.

  However, it is difficult to smoothly move the car unless a skilled engineer has a certain degree of skill in releasing the brake, which is used as a means for moving the car that is stopped and confined to a position where it can be rescued. Especially when the car is stopped on the skip floor where there is no hatch door or emergency rescue exit, the distance to travel is increased by releasing the brake, and passengers confined in the car will be disengaged by the longer distance. You will feel a lot of ups and downs in the car. In addition, the passengers sometimes felt anxiety, distrust, and poor physical condition due to up and down shaking, and it was not possible to fully consider these.

  Therefore, the present invention provides an elevator apparatus and a confinement rescue operation method that can minimize anxiety and distrust of a confined passenger and can be realized by a simple method that does not depend on the skill level of a worker who is rescued. The purpose is to do.

  In order to solve the above-mentioned problem, in the present invention, “at least two or more elevators having a car on one end of a main rope suspended on a hoist equipped with a brake and a weight suspended on the other end are adjacent to each other. An elevator apparatus having an adjacent elevator rescue function that can be rescued by moving a passenger from an arranged and stopped first car to an adjacent second car, using the load of the stopped first car , A first means for estimating a moving direction when the brake of the first car is released, an estimated direction and a position avoiding an obstacle in a space between the adjacent first and second cars Is provided with a second means for moving the second car to the rescue position and waiting, and a third means for releasing the brake of the stopped first car and guiding it to the rescue position. Eleva features It is over device ".

  ADVANTAGE OF THE INVENTION According to this invention, the anxiety and distrust of the trapped passenger can be reduced, and it can be rescued by a simple technique that does not depend on the skill level of the worker who is rescued.

The figure which shows the outline | summary of a general confinement rescue operation (adjacent elevator rescue function).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 6 is a diagram showing an outline of a general confinement rescue operation (adjacent elevator rescue function). In FIG. 6, when the building 100 is a particularly high-rise building (8th floor in the example of FIG. 6), a skip floor FS (4th to 7th floor) without a hatch door may be set. When the elevator car CA of such a high-rise elevator is traveling near the skip floor FS without a hatch door, if the elevator stops for some reason and cannot be restarted, the passenger MA in the car CA is in the elevator. It is trapped and elevator confinement occurs.

  If this elevator stop occurs in the vicinity of a normal floor with hatch doors (in the example of Fig. 6, the first floor to the third floor, the eighth floor), there is a countermeasure to rescue from the nearest floor, but there is no hatch door In the case of the skip floor FS, the rescuer MB enters the car CB adjacent to the car CA from the first floor and heads for rescue. In this case, a confinement rescue operation (adjacent elevator rescue function) is provided as a function for rescue in the occurrence of confinement near the skip floor FS without the hatch door.

  The confinement rescue operation (adjacent elevator rescue function) is specifically performed as follows. First, the elevator car CB of the same type adjacent to the position of the elevator car CA that is stopped and trapped is moved, and the height position is synchronized by a photoelectric device (not shown) provided in the car CA and the car CB. Stop horizontally. This operation is performed by automatic operation, and the car CB can be automatically stopped after operation until the car CA stop position. After the height position synchronization, the rescuer MB in the car CB unlocks the emergency door 7B on the side of the car room of the car CB with a special key, and then opens the emergency door 7A of the car CA from the outside of the car CA. Unlocked, forms a passage between the car CA and the car CB, transfers to the car CA, and by these means, the passenger MA trapped in the car CA is moved to the car CB and rescued. Needless to say, the positions of the emergency doors in the car CA and the car CB are placed opposite to each other.

  The confinement rescue operation (adjacent elevator rescue function) is executed as described above and can safely rescue passengers in a short time. However, in the state where the position of the trapped car CA is stopped near the height position of the building beam 11 shown in FIG. 6, when the car CB is rescued, the building beam 11 of the building becomes an obstacle, and the car CA and the car CB It may be difficult for passengers to move between the two. In such a case, the confinement automatic rescue operation (adjacent elevator rescue function) by the adjacent elevator in the above-described content and procedure cannot be used, and the rescue time may be long.

  In this case, the car CA that has been stopped is moved to a height where the building beam 11 of the building does not interfere, and further measures are required to allow passengers to move between the car CA and the car CB. Consideration should be given to alleviate the anxiety given to passengers. There are many types of anxiety given to passengers, but it can be roughly classified into anxiety caused by a long rescue operation and anxiety caused by the car moving up and down. In the present invention, such anxiety is solved as much as possible, and an attempt is made to realize it by a simple method.

  FIG. 2 is a diagram illustrating an overall configuration of an elevator apparatus that performs an elevator confinement rescue operation (adjacent elevator rescue function).

  In the elevator apparatus of FIG. 2, the first elevator car CA in which the passenger MA is trapped due to a failure and the second elevator car CB on which the worker MB who is a rescue engineer rides are adjacent to each other. Are arranged. Since the two sets of elevator apparatuses have basically the same configuration, the first elevator side will be denoted by the symbol A, and the second elevator side will be denoted by the symbol B.

In the machine room M, hoisting machines 1A and 1B of the first elevator and the second elevator, control panels 2A and 2B, speed governors 3A and 3B, sensors 4A and 4B are installed. The rotational speed of 1B can be adjusted by the control panels 2A and 2B. Further, as will be described later, in the present invention, devices for electrically opening the brake are added to the control panels 2A and 2B, and the brake of the hoisting machine can be operated. When the car stops abnormally, the hoisting machine of this car is automatically braked to prevent movement from the position. The hoistway R has a main rope 5A, Cars CA and CB are suspended from one end of 5B, and suspension weights 9A and 9B are suspended from the other end. Further, governor ropes 6A and 6B are arranged between the governors 3A and 3B and the cars CA and CB. Between the car CA and the car CB in the hoistway R, obstacles such as building beams 11 are arranged at appropriate positions in the height direction.

  In the elevator car CA and the car CB, emergency doors 7A and 7B are arranged on the walls facing each other, and sensors 10A and 10B for irradiating, for example, infrared rays in the direction facing each other are installed. The sensors 10A and 10B are provided at the same height position of the car CA and the car CB, and are configured to sense the reflection of the infrared rays emitted from the car and transmit them to the control panels 2A and 2B as detection signals PA and PB. ing. Also, a plurality of sensors 10A and 10B are installed in the height direction of each car CA, CB, and it is preferable that the height position can be confirmed at least two places above and below the emergency doors 7A, 7B. . In FIG. 2, sensors are installed at two places above and below the emergency doors 7A and 7B. In other cars CA and CB, load detecting devices 8A and 8B in the car are installed. As will be described later, the determination of the position at which rescue is possible and the position at which rescue is impossible can be detected using sensors 10A, 10B installed in the car CA and the car CB, for example.

  According to the structure of the building in FIG. 2, the area where the confinement rescue operation (adjacent elevator rescue function) can be realized is restricted by obstacles such as the building beam 11, and the rescue operation is possible in the area B. In region A, rescue operation cannot be performed.

  In the following description, the description will be made on the premise that equipment for confinement rescue operation (adjacent elevator rescue function) is provided in the control panels 2A, 2B, but in addition to the system permanently installed in the control panels 2A, 2B, You may carry in to a machine room as an apparatus installed separately at the time of emergency, and connect to control panel 2A, 2B and perform a confinement rescue operation (adjacent elevator rescue function). Although the control panel 2A controls the car CA and the control panel 2B controls the car CB, it is assumed here that each other's information is shared and a series of procedures are executed in cooperation with each other. . Further, it is assumed that monitor screens are appropriately installed on the control panels 2A and 2B so that various information including progress and progress can be provided to the worker.

  Through the above-described equipment configuration and the like, at least the detection signals PA and PB from the sensors 10A and 10B of the cars CA and CB and the load detection devices 8A and 8B in the cars CA and CB are provided to the control panels 2A and 2B on the stop car side. Detection signals WA and WB are input. The output is appropriately displayed on the monitor screen, and the release signal S is appropriately given to a brake release device that electrically releases the brake of the hoist 1A. As will be described later, the brake release signal S is preferably given by the operator from the control panel 2B side.

  3, 4, and 5 are diagrams illustrating a determination method for determining whether or not rescue is possible and determining a rescue position when it is impossible. This determination is to confirm and determine whether or not the building beam 11 of the building is an obstacle, and further, the nearest position where the moving distance is the shortest. This process is performed using the detection signals PA and PB by the sensors 10A and 10B through movement in a plurality of height positions shown in these drawings, for example.

  First, FIG. 3 assumes a case where the load WA detected by the load detection device 8A in the car CA is 50% or less in relation to the load of the counterweight 9A. Here, 50% means that the load of the car CA and the lifting weight 9A is equal, 50% or less means that the car CA is lighter, and 50% or more means that the car CA is heavier. ing.

  Therefore, as shown in the scene 30 of FIG. 3, when the brake of the hoist 1A is released, the car CA moves upward. Since it is obvious from the load WA detected by the load detection device 8A that the car CA will move upward due to the release of the brake, the car CB waits at the upper position of the car CA and the car CA approaches. Will wait. What should be a problem at this time is to minimize the travel distance of the car CA as much as possible and to relieve passengers' anxiety. In this case, the shortest rescue position is the nearest position. The rescue position is more desirable as the moving distance of the car CA becomes smaller, but the effect of the present invention can be obtained even if it is not necessarily minimum.

  Further, in the scene 30 of FIG. 3, in the height positional relationship between the car CA that has stopped and the car 1B that has moved from the first floor, the upper sensor 10AU of the car CA among the sensors 10A and 10B receives the building beam 11 from the reflected wave. None of the other sensors detect the building beam 11.

  In this state, in the process of moving the car CB upward as shown in the scene 31, the upper sensor 10BU of the car CB detects the building beam 11 from the reflected wave and further moves the car CB upward. The lower sensor 10BD of the car CB detects the building beam 11 from the reflected wave as shown in the scene 32, and the lower sensor 10BD of the car CB detects the building beam 11 from the reflected wave as shown in the scene 33. Disappear. In the present invention, the car CB is stopped at the position where the lower sensor 10BD of the car CB in the scene 33 no longer detects the building beam 11 from the reflected wave, and the car stops rising here. Wait for. This determines the travel distance of the car CA, which is L in the scene 33 in FIG. The moving distance of the car CA is the height direction distance between the lower sensor 10BD of the car CB and the lower sensor 10AD of the car CA in this state.

  FIG. 4 also assumes a case where the load WA detected by the load detection device 8A in the car CA is 50% or less in relation to the load of the suspension weight 9A. Therefore, as shown in the scene 40 of FIG. 4, when the brake of the hoist 1A is released, the car CA moves upward. Since it is obvious from the load WA detected by the load detection device 8A that the car CA will move upward due to the release of the brake, the car CB waits at the upper position of the car CA and the car CA approaches. Will wait.

  In the scene 40 in FIG. 4, all the sensors 10 </ b> A and 10 </ b> B do not detect the building beam 11 from the reflected wave in the height positional relationship between the stopped car CA and the car 1 </ b> B that has moved from the first floor. In this state, in the process of moving the car CB upward as shown in the scene 41, the upper sensor 10BU of the car CB detects the building beam 11 from the reflected wave and further moves the car CB upward. The lower sensor 10BD of the car CB detects the building beam 11 from the reflected wave as shown in the scene 42, and then the lower sensor 10BD of the car CB detects the building beam 11 from the reflected wave as shown in the scene 43. Disappear. In the present invention, the car CB is stopped at the position where the lower sensor 10BD of the car CB in the scene 43 no longer detects the building beam 11 from the reflected wave, and the car stops rising here. Wait for. This determines the travel distance of the car CA, which is L in the scene 43 of FIG. The moving distance of the car CA is the height direction distance between the lower sensor 10BD of the car CB and the lower sensor 10AD of the car CA in this state.

  3 shows a state in which the building beam 11 is detected in the initial determination, and FIG. 4 shows a state in which the building beam is not detected in the initial determination.

  FIG. 5 assumes a case where the load WA detected by the load detection device 8A in the car CA is 50% or more in relation to the load of the counterweight 9A. Therefore, as shown in the scene 50 of FIG. 5, when the brake of the hoisting machine 1A is released by the control panel 2A, the car CA moves downward. Since it is obvious from the load WA detected by the load detection device 8A that the car CA will move downward due to the release of the brake, the car CB stands by at the lower position of the car CA and the car CA approaches. I will wait for you.

  In the scene 50 of FIG. 5, all the sensors 10B do not detect the building beam 11 from the reflected wave in the height positional relationship between the stopped car CA and the car CB moved from the first floor. In this state, as shown in the scene 51, in the process of moving the car CB upward to bring it closer to the car CA, the upper sensor 10BU of the car CB detects the building beam 11 from the reflected wave and further moves upward. Give up and move down to find the nearest location. In this case, as shown in the scene 52, the car CB is stopped with the position where the upper sensor 10BU of the car CB stops detecting the building beam 11 from the reflected wave as the nearest position, and the stopped car descends here. Wait for This determines the travel distance of the car CA, which is L in the scene 52 of FIG. The moving distance of the car CA is the height direction distance between the lower sensor 10BD of the car CB and the lower sensor 10AD of the car CA in this state.

  According to the determination concept shown in FIGS. 3 to 5 above, the standby position direction of the rescue car is determined to be either up or down depending on the load of the stop car. Also, when waiting on the upper side, the nearest position is the point where the lower sensor of the rescue car no longer detects the building beam 11, and when waiting on the lower side, the nearest position is the upper sensor of the rescue car. Is a point where the building beam 11 is no longer detected. By determining the nearest position, the travel distance of the stop car is minimized.

  In this way, the presence or absence of an obstacle such as the building beam 11 is detected using the sensor signals PA and PB of the sensors 10A and 10B installed in the respective cars CA and CB. As shown in FIG. Is the rescueable position when the sensor signal 10B does not detect a certain distance. In the case where there is an obstacle such as the building beam 11 at the stop position of the car CA, the sensor signals PA and PB are temporarily blocked or the blocking is continued to identify the position where rescue is impossible.

  Also, as shown in FIG. 4, when there is an obstacle such as a building beam 11 between the top and bottom of the sensors 10 </ b> A and 10 </ b> B, the sensor 10 </ b> A of the car CA cannot detect the obstacle 11. However, the car CB operates in the upward direction from the lowest floor, and when the car CA is detected by the sensor 10B, the car CB is driven to a position where the upper and lower sensors are synchronized. Since the upper sensor of the car CB temporarily detects an obstacle such as the building beam 11, the car CB determines that it cannot be rescued at the stop position of the car CA and continues the ascending operation. After that, at the position where there is no building beam 11, the upper sensor passes without detecting an obstacle for a certain distance, and the lower sensor stops at the position where the obstacle is not detected. It is possible to stop the car CB at the nearest position of the cage CA.

  In addition, the stop position of the car CB is a position where there is no obstacle such as the building beam 11, the load detection value immediately before the car CA stops, and the load in the car when the car is stopped are detected and matched. Detects the condition that has been removed, and automatically calculates the upper side or the lower side to determine. As a result, when the car CA is heavily loaded as shown in FIG. 5, the car CA descends when the brake is released. Therefore, the waiting position of the car CB is below the car CA and at the nearest position. Stop automatically. In the case of a stop failure related to a load sensor failure, the worker checks the actual direction of movement when the brake is released, determines whether the stop position of the car CB is correct, and inputs the determination to the brake electric release device. It is better to determine the continuation of the work.

  In addition, when the operation direction of the car CA is opposite to the expected direction from the load when the brake is released, it is necessary to correct the position of the car CB. Until the automatic adjustment of CB to the proper position is completed, the brake release cannot be performed.

  Also, in the event of a stop failure related to a brake failure, this function will allow the brakes to be opened electrically as long as both brakes do not become abnormal, but if an abnormality is detected in both brakes, In the same way as before, the brake is released by manual operation of the lever. In this case, when the car CA completes moving to the horizontal position of the car CB, the buzzer sounds and the car CA is moved to the rescueable position. It is desirable to have a function of notifying the worker B that the has moved.

  In the example of FIG. 3 and the like, the position where the car CA is stopped represents the positional relationship in which the rescue by the car CB is difficult because the building beam 11 of the building is present. In this state, the rescue operation by the car CB is not possible except for moving the car CA. Moreover, in the current general elevator, after the rescue operation is attempted in this state, the rescue operation becomes impossible, so that the rescue procedure is changed, which causes a longer rescue time.

  In the present invention described below with reference to the processing flowchart of FIG. 1, when rescue is possible, it has a function of notifying the rescuer that the rescue is possible in advance. In addition, if the position of the car CA cannot be rescued, in addition to being impossible, it is necessary to release the brake in addition to whether the car CA moves from the stop position of the car CA or the load in the car. Has a function of notifying the worker heading for rescue before the worker arrives.

  A flow chart showing an operation (control) procedure of the elevator apparatus according to the present invention is shown in FIG. This flow is basically configured by using a computer or the like in the control panels 2A and 2B, and the flow proceeds so as to include instruction information from some workers.

  In the first processing step S11 of the processing flow, after the occurrence of confinement, a request for automatic rescue operation is confirmed by, for example, an operation of a changeover switch by a worker who is rescued, and use of this function is started.

  In the next processing step S12, it is confirmed whether or not the stop position of the car CA is a rescueable position. This confirmation may be judged using detection signals from the sensors 10A and 10B of the cars CA and CB, or the height position detected by the position sensor 4A associated with the hoist 1A and the architectural design of the building 100. You may judge by comparing the height position of the building beam 11 described in the document etc.

  If it is a position that can be rescued, in the processing step S13, an automatic rescue operation is performed in which the car CB is moved to the same height position without moving the car CA, and rescue is performed by rescuing passengers by transferring between cars. Completed.

  In this invention, it concerns on the countermeasure especially when it is not a position which can be rescued. In the case where the position is not a rescueable position, the present invention first estimates the moving direction when the brake is released from the load WA of the car CA. The determination for this is processing steps S14 and S15. In processing step S14, when the load WA of the car CA is 50%, the processing proceeds to processing step S18. At this time, it is considered that the weights of the car CA and the suspension weight 9A are equal, and even if the brake is released, there is a possibility that the car CA does not move up and down.

  In process step S14, when the load WA of the car CA is not 50%, it is further confirmed in process step S15 whether or not the load WA of the car CA is 50% or more. When it is 50% or more, the process proceeds to processing step S17, and when it is 50% or less, the process proceeds to processing step S16.

  In process step S16, the car CB is moved to the nearest position above the car CA. In processing step S17, the car CB is moved to the nearest position below the car CA. Here, the nearest position is determined by the method using the detection signals from the sensors 10A and 10B of the cars CA and CB described with reference to FIGS. Alternatively, the nearest position may be determined by comparing the height position detected by the position sensor attached to the hoist 1 </ b> A and the height position of the building beam 11 on the structure of the building 100.

  The determination of the moving direction in the processing steps S14 and S15 is based on the assumption that when the load WA in the car CA is less than half of the load on the elevator, the brake is released according to the weight on the side of the suspension weight 9A. The car CA is taking advantage of the rise. Therefore, in the processing step S16, the car CB is controlled to automatically stop at a position above the stop position of the car CA and at a position closest to the position where there is no obstacle such as the building beam 11.

  Similarly, when the load WA in the car CA is more than half of the load weight of the elevator, it is utilized that the car CA is lowered when the brake is released due to the weight on the side of the suspension weight 9A. . Therefore, in the processing step S17, the car CB is controlled to automatically stop at the nearest position where there is no obstacle such as the building beam 11 below the stop position of the car CA.

  In order to move the car CA to the nearest position where the car CB stands by, in step S20, the car CA is electrically brake-released. Specifically, for example, the operator is informed in advance that the brake is required to be released, so the worker prepares to release the brake of the car CA in the machine room M, and the car CB is the nearest. After stopping at the position, the brake CA is released electrically.

  The electric brake release is performed only when a failure signal from the control panel 2A of the stopped car CA is transmitted to the control panel 2B of the car CB and there is a failure signal in the control panel 2B. It has a structure that can be operated from. The reason for this is that the state management and control of the two cars can be performed in one place, and the rescue operation is directly performed by the control panel 2A that may be involved in the cause of the stoppage failure of the car CA. There is also the implication of improving the reliability by eliminating.

  As a result, it is possible to apply an open current to the brake of the car CA from the control panel 2B of the car CB. For actual release, an electric signal is sent by operating a brake release push button, etc. Manipulate the current possible. Also, even when the brake release push button is pressed once, the release time does not flow beyond the upper limit set time, and if there is a mechanical malfunction of the brake release push button, or if the operation is incorrect Therefore, even when the brake release push button is continuously operated, safety is taken into consideration so that the brake release time does not exceed a certain value.

  In processing step S21, it is determined whether or not the direction (up or down) in which the car CA has moved by releasing the brake is the same as the direction determined from the load WA in processing steps S16 and S17. If they are the same, the process proceeds to processing step S22, and if they are not the same, the process proceeds to processing step S23.

  In the processing step S22, the car 10 is detected by the sensor 10B of the car CB to be synchronized with the result that the car CA is close to the horizontal position of the car CB as a result of intermittently releasing the brake by the push button for releasing the brake. The brake electric release is controlled to the position where the height position is the same). If it is confirmed that this has reached the same height position, the rescue operation is executed. When the car CB sensor 10B finally detects that the car CA is almost level with the car CB, the brake cannot be released even if the brake release button is pressed. Yes.

  If there is a difference in the direction of movement contrary to expectation, the car CB is moved to the nearest position in the direction in which the car CA actually moved in processing step S23. Since the subsequent operation is a repetition of the processing step S20 to the processing step S22, a detailed description is omitted.

  In the processing step S14, in the state where it is determined that it is 50% and it is estimated that the vehicle does not move in either the upper or lower direction even if the brake is released, the following processing is performed.

  When the load of the car CA is exactly half of the load, even if the brake is released, the car CA is in a state of neither rising nor lowering because it is suspended from the weights. In this case, the car CB stands by at the nearest rescue position where the operation direction due to the load is ignored from the stop position of the car CA (processing step S18). The operator is notified of whether to do this (processing step S34).

  Moreover, since the brake electric release time when the load is suspended is set longer than that when the load is unbalanced, the car can be moved by hand-running operation (processing step S25). Even in this case, if the brake release button is released, the electrical release of the brake will be cut off, so if the car accelerates during the turning operation, the operation of the brake release button will be interrupted. Can be released and the car can be stopped.

  When the car CB sensor detects the car CA and the car moves to the horizontal position, the brake release is forcibly cut off and the buzzer sounds to inform that the horizontal height of the car position is the same ( Processing step S26) makes it possible to match the stop position. In this way, the worker permits the brake release operation and presses it down, but by controlling the brake release almost automatically, the movement and stop position of the car CA should not change depending on the skill level of the worker. Is possible.
