Description

  The present invention relates to an elevator restoration operation apparatus equipped with a three-level seismometer of a high sensor, a low sensor, and an ultra-low sensor, and an elevator earthquake restoration service providing system.

In general, elevator control operations during earthquakes are equipped with ultra-low detectors and low-sensor seismometers, and when the ultra-low sensor seismometers are operated, the car stops at the nearest floor and is low within a certain time. If the seismometer of the sensor does not operate, it is automatically restored and the elevator returns to normal operation.
If the seismometer of the low sensor operates within a certain period of time, it will be in a state where the elevator is stopped until it has been confirmed by a maintenance / inspection technician whether there is any damage to the elevator or whether there is any abnormality. .
The number of earthquakes and the number of seismometer operations are both increasing, with an average of about 8000 seismometers operating on average per year, after which the elevator is being restored.
According to the results of analyzing earthquake occurrence data from the data of the past three years, the number of property damage accidents caused by medium and small-scale earthquakes with seismic intensity 4 or less is only 1, and the incidence is 0.014. %, Which is an extremely low value. When this became a large-scale earthquake with a seismic intensity of 5 or more, the incidence was found to be significantly higher at 1.12%.
However, if an earthquake with a seismic intensity of about 4 occurs in a densely populated area, many elevator seismometers will operate, and maintenance and inspection specialists with maintenance contracts will go around for inspection. Become. Therefore, if the seismometer operates in a wide range, it will operate on the scale of several hundreds or thousands of units. Even if hundreds of professional engineers respond to the inspection and restoration of elevators. It takes time, and elevator users in buildings and condominiums will not be able to use the elevator until inspection or restoration is completed.
In general, an elevator maintenance company has a system in which the elevator and the maintenance company are connected by a telephone line, and the status of failure and seismometer operation can be received by the reception system of the maintenance company.

As a conventional technique, during a recovery operation of a medium-scale earthquake, a recovery manual operation is performed, and it is determined whether it is normal or not based on the time required for the manual operation, and the normal operation is performed (for example, patents) Reference 1).
Further, as another conventional technique, there is known a technique that performs an abnormality detection operation of a slow speed traveling when an earthquake detector is operated, and determines the presence or absence of an abnormality by detecting a collision attached to an upper part or a lower part of a car (for example, Patent Document 2 reference).
Furthermore, as another conventional technique, for an elevator that is stopped in the control operation at the time of an earthquake, abnormality detection by the sensor and pressure abnormality detection to the control cable are performed. If there is no problem, it is known that it recovers (for example, see Patent Document 3).

JP 2003-146552 A JP 2002-128408 A JP-A-6-247657

In the case of the conventional patent document 1, the mechanism for detecting earthquake anomalies is insufficient, and in the unlikely event that the counterweight is off, or the control cable is hooked on the hoistway device, the car and the counterbalance There was a risk of collision of weights or disconnection of the control cable.
Moreover, in the thing of patent document 2, when the mechanism of an earthquake abnormality detection is inadequate and a control cable should be caught by a hoistway apparatus by any chance, the disconnection accident of a control cable may generate | occur | produce. Yes, it takes a lot of time to restore the control cable.
Furthermore, the method described in Patent Document 3 is insufficient in the method for detecting an abnormality. Even if the control cable is hooked on the hoistway device, it cannot be detected because there is no change in the pulling pressure during the stop. For example, running and catching after a test operation of 1000 mm leads to disconnection of the control cable. In addition, the weight of the control cable changes depending on the length of lifting, and changes from several meters to the weight of the length of the lifting process, so it must be determined that there is an abnormality beyond that, If the control cable gets caught in the hoistway equipment, the sensor cannot be detected even if the control cable is pulled up with considerable force.

The present invention has been made to solve the above-described problems, and performs an earthquake recovery operation at an earthquake level where almost no equipment damage occurs during seismometer operation, and an earthquake level at which equipment damage is likely to occur. Alternatively, it is an object of the present invention to provide an elevator restoration operation device for an elevator that avoids restoration operation at an earthquake level where a problem is likely to occur in restoration operation.
In addition, if the earthquake recovery operation has been completed, report it to the reception center of the elevator maintenance company, and the maintenance engineer will not be able to perform the earthquake recovery operation, and will be able to travel efficiently to other elevators that require inspection. Provide a system for providing earthquake recovery services.

  In the elevator restoration operation device according to the present invention, the ultra-low sensor that operates when the first reference value is exceeded, and the low sensor that operates when the second reference value that is larger than the first reference value is exceeded. And a high sensor seismometer that operates when a third reference value that is greater than the second reference value is exceeded, and when the first reference value is exceeded, the ultra-low sensor operates to minimize the elevator car. When the floor is stopped and the second reference value is exceeded and less than the third reference value, the low sensor operates to perform an earthquake diagnosis operation in which the elevator abnormality is detected, and the elevator abnormality cannot be detected. In this case, the elevator is automatically restored.

  In addition, when the low sensor operates above the second reference value and below the third reference value, the elevator car is stopped on a specific floor such as the first floor or the lobby floor. An earthquake diagnosis operation is performed to detect an abnormality of the elevator, and when the abnormality of the elevator cannot be detected, the elevator is automatically restored.

  In the elevator restoration service providing system according to the present invention, the ultra-low sensor that operates when the first reference value is exceeded, and the elevator that operates when the second reference value that is larger than the first reference value is exceeded. A low sensor and a high sensor seismometer that operates when a third reference value greater than the second reference value is exceeded, and when the first reference value is exceeded, the ultra-low sensor operates and the elevator When the car is stopped at the nearest floor and the second reference value is exceeded and less than the third reference value, the low sensor operates to detect an elevator abnormality and perform an elevator diagnosis. If the elevator cannot be detected, the elevator is automatically restored, and if an elevator abnormality is detected, the elevator is automatically restored and the earthquake maintenance operation notifying message is sent to the elevator maintenance company and the third reference value is set. Beyond When the sensor is operating, one in which avoid the automatic recovery of the earthquake diagnosis operation and elevator, it is determined that the restoration work by a maintenance technician to send the earthquake recovery operation can not report to the elevator maintenance company.

According to the present invention, most elevators during seismometer operation are capable of seismic diagnosis operation, and most of the elevators are automatically diagnosed for abnormal conditions, and elevators that do not have problems can be automatically restored.
According to the present invention, elevator users of buildings and condominiums that are stopped on a specific floor such as the first floor or the lobby floor and can be restored are automatically checked after a few minutes after the earthquake, and the elevator is usually It can be used on the street.
On the other hand, in the case of an elevator maintenance company, when an earthquake occurs, the number of cases in which a seismometer operates and stops is quickly patrolled and restored, and the service to elevators that have truly failed due to the earthquake is drastically reduced. Can be done quickly.

In FIG. 1, when an earthquake occurs and the seismometer of the low sensor operates, the elevator stops at the nearest floor, and the door is closed and cannot be used. Usually, a maintenance / inspection engineer inspects the elevator to check whether there is an abnormality.
In general, a communication device 30 dedicated to a maintenance company is connected to the elevator control circuit 6, and information on seismometer operation such as failure information via a telephone line 31 is also included in the communication system 32 of the reception system 34 of the elevator maintenance company. To the receiving terminal 33. The reception system 34 of the elevator maintenance company has received this signal and the technical knowledge of maintenance / inspection based on the communication that the elevator and the user of the elevator building and the administrator have received the telephone contact. The person 35 is dispatched to the building. The present invention is intended to automate these.

In FIG. 2, an elevator car 1 is connected to a counterweight 3 by a main rope 2, and the main rope 2 is wound around a hoisting machine 4. The car 1 is connected to a control circuit 6 installed in a machine room or the like by a control cable 5 and includes an in-car interphone 7.
The seismometer according to the present invention includes an ultra-low sensor 21 having a return coil 20 that operates when a first reference value is exceeded, and a return coil 18 that operates when a second reference value greater than the first reference value is exceeded. And a three-stage seismometer with a high sensor 17 without a return coil that operates when a third reference value greater than the second reference value is exceeded. In a low-scale earthquake with a seismic intensity of 3 or less, the ultra-low sensor 21 operates. When the ultra-low sensor 21 operates, the elevator performs the nearest floor stop operation and operates the return coil 20 after a certain time. Then, the seismic control operation control 16 performs the operation to return to the normal operation.
Further, in a medium-scale earthquake with a seismic intensity of 4 or less, the low sensor 19 is in an operating range. When the low sensor 19 is operated, the mode is set to the earthquake recovery operation under the condition that the high sensor 17 is not operating. The earthquake operation control device 15 controls the earthquake restoration operation.
The earthquake control operation control device 16 and the earthquake restoration operation control device 15 are executed in the elevator control circuit 6. The elevator car 1 is provided with a cable catch detection device 45 and a counterweight collision detection switch 8. Further, the intercom 7 in the car is utilized when executing the abnormal sound detection function during an earthquake.
The earthquake operation control device 15 includes an earthquake operation state confirmation means 10, a sensor return circuit 11, a slow speed abnormality detection operation circuit 12, a manual speed abnormality detection operation circuit 13, and a high speed abnormality detection operation circuit 14.

Here, the conditions of the elevator earthquake recovery operation will be described first.
The purpose of the elevator earthquake restoration operation according to the present invention is to automatically restore a level where there is usually almost no damage to the elevator equipment due to the earthquake in the occurrence of an earthquake of medium and low scale.
When the sensitivity of the seismometer is very low, for example, seismic intensity is 3 or less, if the seismometer with low sensitivity does not operate even in the present situation, it will be automatically restored after a certain time.
As mentioned above, the inventor analyzed the data of 129 earthquakes registered in the information system from the data for the past three years. The fact is that there is only one out of thousands, and the rate of occurrence is as low as 0.014%, and if this is a large earthquake with a seismic intensity of 5 or more, the rate of occurrence is 1.12%. The fact that the fact that it is extremely high was obtained as knowledge can be a very important factor in aiming at the efficiency of the earthquake recovery operation of elevators and the early restoration of elevators in areas where buildings are crowded.
Therefore, in the present invention, the level of the seismometer is set to three levels. That is, if the current low-sensing seismometer does not operate, there is almost no problem with the ultra-low detector 21 whose level of the seismometer is automatically restored after a certain time and the automatic restoration operation. Low sensor 19 of seismometer level (for example seismic intensity of 4 or less) and seismometer level higher than that, high sensitivity that is likely to cause abnormalities and likely to cause problems in automatic recovery operation There are three stages of the high detector 17 (for example, seismic intensity 5 or more). For highly sensitive seismic levels, it will be an inspection area where specialists for maintenance and inspection are dispatched.

Next, the configuration of each device for minimizing device damage due to an earthquake will be described.
As a condition for the restoration operation at the time of the earthquake, the elevator car at the time of the earthquake is conditional on being stopped on a specific floor such as the first floor or the lobby floor, for example. Elevator cars normally stand by on a specific floor such as the first floor or lobby floor if no user calls are made, and most of them stop at a specific floor when the frequency of use by the user is low. It is common.
Therefore, the structure of a guide rail for minimizing equipment damage when an earthquake occurs will be described.
FIG. 3 shows a structure for supporting an elevator car guide rail or a counterweight guide rail. A rail bracket 51 is fixed to the hoistway wall 50 with anchor bolts, and the elevator car or counterweight guide rail is used. 53 and 54 are fixed by a rail clip 52.
Here, the fact that the car is stopped on a specific floor such as the first floor or the lobby floor, which is the above condition, is a condition for earthquake recovery operation, so that the car stops on the first floor or the specific floor such as the lobby floor. The number of rail brackets 51 and rail clips 52 attached to the car guide rail 53 in the vicinity of the elevator car 1 is increased as compared with other parts. This reinforces the strength of the car guide rail near the specific floor. Similarly, the number of rail brackets 51 and rail clips 52 to which the counterweight guide rails 54 are fixed in the vicinity of the counterweight 3 stopped near the top floor of the hoistway is increased more than the other portions. This reinforces the strength of the counterweight guide rail 54 near the top floor of the hoistway.
Furthermore, in the vicinity of the elevator car 1 stopped on a specific floor such as the first floor or lobby floor, the car guide rail 53 itself and / or the counterweight 3 stopped near the top floor of the hoistway. The balance weight guide rail 54 itself may be made of a material having a higher bending strength than other guide rails, such as a stainless steel material or a stainless alloy, to increase the strength.

Next, a governor rope support device for minimizing equipment damage due to an earthquake will be described.
As shown in FIGS. 4 and 5, a ring portion through which the governor rope 62 is inserted so that the governor rope 62 attached to the side surface of the elevator car 1 does not cross or catch in the middle of the hoistway. A plurality of governor rope guides 60 comprising 60a and support arms 60b for attaching to the hoistway or the like are attached so as to be substantially equidistant in the vertical direction of the hoistway. In this governor rope guide 60, the method of inserting and supporting the governor rope 62 located on the side close to the side wall of the hoistway is effective in preventing the governor rope from being caught. In the figure, 61 is a governor-carrying wheel provided at the lower part of the hoistway.

Next, the configuration of the control cable catch detection device for minimizing equipment damage due to an earthquake will be described.
It is necessary to detect whether or not the elevator control cable 5 is caught in equipment, protrusions, etc. in the hoistway during the abnormality detection operation during the earthquake recovery operation. For this purpose, a control cable catch detection device 45 as shown in FIGS. 6 and 7 is provided.
A cable catching detection arm 45 is fixed to the bottom of the elevator car frame 44, and is usually fixed in a vertical direction (car raising / lowering direction) by a tension spring 46. A ring portion 45 a through which the control cable 5 is inserted is provided at the lower end portion of the cable catch detection arm 45.
The control cable 5 is hung on a cable hanger 41 under a car, is bound and fixed by a cable clip 42, and the control cable 5 connected to the control circuit 6 side provided in the machine room or the like is connected to the cable catch detection arm. 45 is inserted through the ring portion 45a, hangs down, and further folded upward to be connected to a control circuit 6 provided in a machine room or the like.
Normally, even if the car 1 moves up and down in the vertical direction, the control cable 5 moves straight as it is, so that the cable catch detection arm 45 is fixed in a vertical state as shown in FIG. The control cable catch detection switch 40 provided at the bottom of the car frame 44 does not operate.
However, if the control cable 5 is caught by a hoistway device or projection 47 due to an earthquake, the cable catch detection arm 45 is tilted by the control cable 5 as shown in FIG. The control cable catching detection switch 40 is operated, and an abnormality of the control cable 5 is detected.

Next, the configuration of a counterweight collision detection switch for minimizing equipment damage due to an earthquake will be described.
Only when the elevator car 1 is stopped on the first floor or a specific floor such as the lobby floor and the counterweight is waiting on the top floor of the hoistway, the recovery operation in the event of an earthquake is started. However, it is necessary to detect whether or not the car 1 collides. For this purpose, a counterweight collision detection device as shown in FIGS. 9, 10, and 11 is provided.
A counterweight collision detection switch 8 is installed in the upper part of the elevator car 1 on the counterweight side. A collision detection bar 60 is attached to the counterweight collision detection switch 8 at a position away from the counterweight 3 at a predetermined interval. The collision detection bar 60 is always urged upward by a spring 61. When the collision detection bar 60 hits the counterweight 3 and falls down as shown by the arrow in FIG. 11, the counterweight collision detection switch 8 operates. ing. Thereby, the deviation of the counterweight 3 is detected abnormally.

Next, the abnormal sound detection device during the recovery operation will be described.
Enables sound pressure detection of the intercom 7 in the elevator car 1 during earthquake recovery operation, and detects abnormal sounds and collision sounds using the interphone 7 in the car, especially during abnormal detection operation during earthquake recovery. To detect anomalies caused by abnormal sounds.

Next, the operation flow of the elevator earthquake recovery operation will be described with reference to FIG.
In Step S1, it is determined in Step S2 whether the low sensor 19 is operating and the high sensor 17 is not operating in the seismic control operation control device 16. If this condition is not met in step S2, the restoration operation is stopped, and an earthquake restoration operation impossibility notification is transmitted to the elevator maintenance company reception system 34 in step S3 and terminated (S4).
In this case, since the seismometer of the low detector 19 is operating, the process proceeds to step S5, and the communication device 30 notifies the elevator maintenance company receiving system 34 of the earthquake detector operation notification.
Next, it progresses to step S6 and an earthquake restoration driving | operation is started. First, when the low detector 19 of the earthquake detector operates, the elevator control circuit 6 obtains data (earthquake recovery operation condition) on whether the operation state of the elevator is stopped on a specific floor such as the first floor or the lobby floor. The operation state confirmation means 10 at the time of earthquake confirms from the memory (step S7). If the car is stopped on a specific floor such as the first floor or the lobby floor in step S8, the return coil 20 is operated by returning the ultra-low sensor 21 in step S9. Next, in step S10, the return coil 18 is operated by the return of the low sensor 19. These return operations are performed by the sensor return circuit 11.
After the seismometers of the ultra-low sensor 21 and the low sensor 19 are restored, the car 1 is operated at a low speed by the slow speed abnormality detection operation circuit 12 at step S11, the slow speed abnormality detection operation is performed, and the up operation to the top floor is performed. Further down operation to the lowest floor is performed. Here, the slow speed operation is, for example, an elevator with a speed of 60 m / min and a speed of about 1/10 or about 5 m / min.
Then, in the next step S12, abnormal sound detection during traveling, control cable catch detection, and counterweight collision detection on the counterweight are carried out.
If an abnormality is detected in step S12, the process proceeds to step S3, the earthquake recovery operation is stopped, an earthquake recovery operation impossibility notification is transmitted to the elevator maintenance company reception system 34, and the process ends (step S4).
Returning to the first floor in the above step S11, the speed abnormality detection operation is completed, and if no abnormality is detected in step S12, the manual speed abnormality detection operation circuit 13 performs the manual speed abnormality detection operation in step S13. Similarly, up operation to the top floor and further down operation to the bottom floor are performed. The manual speed operation here refers to a speed of about 15 m / min which is set as a speed at the time of maintenance and inspection.
Then, in the next step S14, abnormal sound detection during traveling, control cable catch detection, and counterweight collision detection on the counterweight are carried out.
If an abnormality is detected in step S14, the process proceeds to step S3, the earthquake recovery operation is stopped, an earthquake recovery operation impossibility notification is transmitted to the elevator maintenance company reception system 34, and the process ends (step S4).
Furthermore, in the earthquake recovery operation, when the manual speed abnormality detection operation is completed and no abnormality is detected in step S14, the car 1 is subjected to the high speed abnormality detection operation circuit 14 in step S15, and similarly the top Run up to the floor and down to the lowest floor.
Then, in the next step S16, abnormal noise detection during traveling, control cable catch detection, and counterweight collision detection on the counterweight are carried out.
If an abnormality is detected in step S16, the process proceeds to step S3, the earthquake recovery operation is stopped, an earthquake recovery operation impossibility notification is transmitted to the elevator maintenance company reception system 34, and the process ends (step S4).
If no abnormality is detected in step S16, the process proceeds to step S17, where it is determined that no damage has been detected in the elevator, and the elevator is restored to normal operation. Thereafter, in step S18, an earthquake restoration notification is issued to the elevator maintenance company reception system 34 to inform the elevator that the earthquake restoration has been completed.
Thus, the elevator finishes the earthquake recovery operation (step S4).

As described above, according to the first embodiment, conventionally, in the occurrence of a medium-scale earthquake with a seismic intensity of about 4, it is possible to distinguish seismic intensity 4 or seismic intensity 6 even though there is almost no equipment abnormality. Because there is a case where there is an abnormality even with seismic intensity 4, the current seismometers of elevators require operation by maintenance and inspection specialists for seismometer operation exceeding ultra-low sensitivity. Automatic inspection can be performed. As a result, most of the elevators during the operation of the seismometer can be automatically inspected, and most of the elevators are automatically diagnosed for abnormal conditions, and elevators free from problems can be automatically restored.
In addition, according to the first embodiment, elevator users of buildings and condominiums that can be restored and stopped on a specific floor such as the first floor or lobby floor, have completed automatic inspection within a few minutes after the earthquake. Thus, the elevator can be used as usual.
On the other hand, in the case of an elevator maintenance company, when an earthquake occurs, the number of elevators that are stopped due to the operation of the seismometer has been reduced rapidly, and the number of elevators that have truly failed due to the earthquake has been drastically reduced. The service can be performed quickly.

Hangs down after leaving the cable clip 42 and is further folded back and connected to the control circuit 6 provided in the machine room or the like. The upper and lower ends of the cable catch detection arm 45 are rotatably fixed between the bottom of the elevator car frame 44 and the cable clip 42, and are usually fixed in a slightly inclined state as shown in the figure.
Normally, even if the car 1 moves up and down in the vertical direction, the control cable 5 moves straight as it is, so that the cable catch detection arm 45 is fixed in a slightly inclined state as shown in FIG. The control cable catching detection switch 40 provided at the center of the bottom of the car frame 44 does not operate.
However, if the control cable 5 is caught by a hoistway device or protrusion 47 due to an earthquake, the cable catch detection arm 45 is further pulled by the catch of the control cable 5 and further tilted to catch the control cable. The detection switch 40 is operated, and an abnormality of the control cable 5 is detected.
