Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1.
FIG. 1 is a configuration diagram showing a soundness diagnostic apparatus according to the first embodiment of the present invention. In the figure, an elevator 2 is installed in the building 1. The elevator 2 includes a hoistway 3, a car 4, a balance weight (not shown), a hoisting machine 5, a suspension body 6, and an elevator control device 7.

The car 4 and the balance weight are suspended in the hoistway 3 by the suspension body 6. As the suspension body 6, a plurality of ropes or a plurality of belts are used.

The hoisting machine 5 is installed in a machine room provided above the hoistway 3 or at the top of the hoistway 3. Further, the hoisting machine 5 has a drive sheave 8, a motor (not shown), and a brake (not shown). The motor rotates the drive sheave 8. The brake keeps the drive sheave 8 stationary or brakes the rotation of the drive sheave 8.

The suspension body 6 is wound around the drive sheave 8. The car 4 and the balance weight move up and down in the hoistway 3 by rotating the drive sheave 8. The elevator control device 7 controls the operation of the car 4.

An earthquake detector 9 and a state detector 10 are installed in the building 1. The state detector 10 is provided in the elevator 2. Further, the state detector 10 detects the state of the elevator equipment included in the elevator 2. That is, the state detector 10 generates a signal according to the state of the elevator equipment. The signal from the earthquake detector 9 and the signal from the state detector 10 are input to the diagnostic device main body 11.

The soundness diagnostic device of the first embodiment includes a state detector 10 and a diagnostic device main body 11. The diagnostic device main body 11 diagnoses the soundness of the building 1 and the elevator 2 after an earthquake, which is at least one of the buildings 1 and the elevator 2, by using the information from the state detector 10.

The diagnostic device main body 11 of the first embodiment determines whether or not there is an abnormality that hinders the restart of the automatic operation of the elevator 2 as the soundness of the diagnosis target after the occurrence of the earthquake.

Further, the diagnostic apparatus main body 11 has an acquisition unit 12, a storage unit 13, a determination unit 14, and a timer 15 as functional blocks. The acquisition unit 12 periodically acquires information from the state detector 10. The storage unit 13 stores a reference value corresponding to a state value indicating the state of the elevator equipment before the occurrence of the earthquake.

The determination unit 14 determines whether or not there is an abnormality in the diagnosis target after the occurrence of the earthquake by comparing the post-earthquake detection value, which is a state value indicating the state of the elevator equipment after the occurrence of the earthquake, with the reference value.

The reference value is, for example, a state value before the occurrence of an earthquake or a value obtained by adding an allowable value to the state value before the occurrence of an earthquake. When the state value before the occurrence of an earthquake is used as the reference value, the determination unit 14 determines that there is an abnormality when the difference between the reference value and the detected value after the earthquake exceeds the permissible value. When the value obtained by adding the permissible value to the state value before the occurrence of the earthquake is used as the reference value, the determination unit 14 determines that there is an abnormality when the detected value after the earthquake exceeds the reference value.

The storage unit 13 periodically updates the reference value at the timing of acquiring the information from the state detector 10.

FIG. 2 is a flowchart showing the operation of the diagnostic apparatus main body 11 of FIG. The diagnostic device main body 11 periodically executes the process of FIG. 2 at a set cycle. First, in step S1, the diagnostic apparatus main body 11 confirms whether or not an earthquake having a seismic intensity equal to or higher than the set seismic intensity is detected by the earthquake detector 9.

When no earthquake is detected, the diagnostic device main body 11 acquires the information from the state detector 10 in step S2. Then, in step S3, the diagnostic apparatus main body 11 updates the reference value and ends the process of that time.

When an earthquake is detected, the diagnostic device main body 11 confirms in step S4 whether or not the shaking has subsided based on the information from the earthquake detector 9. If the shaking has not subsided, the diagnostic device main body 11 ends the process at that time.

When the shaking has subsided, the diagnostic device main body 11 confirms in step S5 whether or not the set time has elapsed. If the set time has not elapsed, the diagnostic device main body 11 ends the process at that time.

When the set time has elapsed, the diagnostic apparatus main body 11 acquires the information from the state detector 10 in step S6. Then, in step S7, the diagnostic apparatus main body 11 determines whether or not there is an abnormality in the diagnosis target. Subsequently, in step S8, the diagnostic device main body 11 outputs the determination result to the elevator control device 7 and the remote control room, and ends the process.

FIG. 3 is a configuration diagram showing an installation state of the state detector 10 of FIG. The elevator equipment of the first embodiment is a guide rail 21. The guide rail 21 is installed in the hoistway 3 along the vertical direction. Further, the guide rail 21 guides the raising and lowering of the car 4 or the balance weight.

Further, the guide rail 21 is held by a plurality of rail brackets 22. The rail brackets 22 are fixed to the hoistway wall 3a at intervals in the vertical direction. Further, the lower end of the guide rail 21 is separated from the bottom surface of the hoistway 3 even in a normal state.

The state detector 10 of the first embodiment detects the position of the lower end of the guide rail 21 in the vertical direction as the state of the elevator equipment. That is, the state detector 10 of the first embodiment is a displacement detector.

When the building 1 is deformed by the earthquake, for example, when the hoistway wall 3a is deformed from the state of the broken line in FIG. 3 to the state of the solid line, the guide rail 21 is also deformed. Then, the lower end of the guide rail 21 is displaced upward. The determination unit 14 determines whether or not there is an abnormality in the diagnosis target after the occurrence of an earthquake by comparing the position of the lower end of the guide rail 21 with the reference value.

In such a soundness diagnosis device, a state detector 10 for detecting the state of the elevator equipment is provided in the elevator 2. Then, using the information from the state detector 10, the soundness of the diagnosis target after the occurrence of the earthquake is diagnosed. Therefore, with a compact configuration, it is possible to diagnose the soundness of the diagnosis target after an earthquake.

Further, the diagnostic device main body 11 determines whether or not there is an abnormality in the diagnosis target after the occurrence of the earthquake by comparing the post-earthquake state value with the reference value. Therefore, it is possible to more accurately diagnose the soundness of the diagnosis target after the occurrence of an earthquake.

Further, the diagnostic apparatus main body 11 periodically acquires information from the state detector 10 and periodically updates the reference value. Therefore, it is possible to eliminate changes over time and estimate the damage caused by the earthquake more accurately.

Further, the state detector 10 is a displacement detector that detects the position of the lower end of the guide rail 21. Therefore, the configuration can be further made compact.

As the state detector 10, a mechanical switch operated by displacement of the lower end of the guide rail 21 may be used.

Further, the lower end of the guide rail 21 may be lowered due to the shrinkage of the building 1 due to the earthquake. Therefore, a reference value may be set when the lower end of the guide rail 21 is lowered.

Further, two or more state detectors 10 may be used to detect the positions of the lower ends of the two or more guide rails 21.

Further, in the above example, the reference value and the post-earthquake detection value are compared, but the amount of change in the state value within the set time is compared with the amount of change threshold, and when the amount of change exceeds the amount of change threshold, an abnormality occurs. It may be determined that there is.

Embodiment 2.
Next, FIG. 4 is a configuration diagram showing a main part of the soundness diagnosis device according to the second embodiment of the present invention. The elevator equipment of the second embodiment is a speed governor rope tensioning vehicle 23. The governor rope tensioning vehicle 23 is provided at the lower part of the hoistway 3.

Further, the speed governor rope tensioning wheel 23 can be moved in the vertical direction by being guided by a tensioning wheel guide device (not shown). Further, the movement of the speed governor rope tensioning wheel 23 in the horizontal direction is regulated by the tensioning wheel guide device.

A speed governor 24 is installed above the hoistway 3. The governor 24 has a governor sheave 25. The governor rope 26 is wound around the governor sheave 25 and the governor rope tensioning vehicle 23. The speed governor rope 26 is arranged in an annular shape in the hoistway 3.

The governor rope 26 is connected to the car 4. As a result, when the car 4 travels, the speed governor sheave 25 rotates at a speed corresponding to the traveling speed of the car 4.

The state detector 27 of the second embodiment detects the vertical position of the speed governor rope tensioning wheel 23 as the state of the elevator equipment. That is, the state detector 27 of the second embodiment is a displacement detector.

When the building 1 is deformed by the earthquake and the hoistway 3 is deformed as shown in FIG. 4, for example, the speed governor 24 is displaced in the horizontal direction from the position of the broken line to the position of the solid line. As a result, the governor rope tensioning wheel 23 is displaced upward. The determination unit 14 compares the position of the governor rope tensioning vehicle 23 with the reference value, and determines whether or not there is an abnormality in the diagnosis target after the occurrence of the earthquake. Other configurations and operations are the same as those in the first embodiment.

Even with such a soundness diagnosis device, it is possible to diagnose the soundness of the diagnosis target after an earthquake with a compact configuration.

In addition, the soundness of the diagnosis target after the occurrence of an earthquake is diagnosed from the amount of lift of the governor rope tensioning vehicle 23 according to the deformation of the building 1. Therefore, the configuration can be further made compact.

As the state detector 27, a mechanical switch operated by the displacement of the governor rope tensioning wheel 23 may be used.

In addition, the speed governor rope tensioning vehicle 23 may extremely descend due to the shrinkage of the building 1 due to the earthquake. Therefore, a reference value may be set when the governor rope tensioning vehicle 23 descends.

Further, in the above example, the reference value and the post-earthquake detection value are compared, but the amount of change in the state value within the set time is compared with the amount of change threshold, and when the amount of change exceeds the amount of change threshold, an abnormality occurs. It may be determined that there is.

Embodiment 3.
Next, FIG. 5 is a configuration diagram showing a main part of the soundness diagnosis device according to the third embodiment of the present invention. The elevator equipment of the third embodiment is a rail bracket 22. Further, in the third embodiment, a plurality of state detectors 28 are used. Each state detector 28 is provided on the corresponding rail bracket 22.

Each state detector 28 of the third embodiment detects the deformation of the corresponding rail bracket 22 as the state of the elevator equipment. That is, each state detector 28 of the third embodiment is a deformation detector. Examples of the deformation detector include a strain gauge.

The diagnostic device main body 11 compares the total amount of deformations detected by all the state detectors 28 with the reference value to determine the presence or absence of an abnormality. Further, the diagnostic device main body 11 may determine the presence or absence of an abnormality by comparing the maximum value of the deformation amount detected by all the state detectors 28 with the reference value. Other configurations and operations are the same as those in the first embodiment.

Even with such a soundness diagnosis device, it is possible to diagnose the soundness of the diagnosis target after an earthquake with a compact configuration.

Further, since the presence or absence of an abnormality to be diagnosed is determined from the amount of deformation of the rail bracket 22, the configuration can be further made compact.

Further, by providing the state detector 28 on the two or more rail brackets 22, more accurate diagnosis can be performed.

The number of rail brackets 22 to which the state detector 28 is provided is not particularly limited.

Embodiment 4.
Next, FIG. 6 is a configuration diagram showing a main part of the soundness diagnosis device according to the fourth embodiment of the present invention. The elevator equipment of the fourth embodiment is a car 4 as an elevating body.

The state detector 29 of the fourth embodiment is installed at the top of the hoistway 3. Further, the state detector 29 of the fourth embodiment detects the horizontal position of the car 4 as the state of the elevator equipment. Further, as the state detector 29 of the fourth embodiment, an optical detector, for example, a camera is used.

After the earthquake, the car 4 has stopped. The diagnostic device main body 11 of the fourth embodiment acquires the vertical position information of the car 4 from the elevator 2 after the occurrence of the earthquake.

The position information to be acquired is, for example, a signal from a car position detector provided in the hoisting machine 5. In this case, the diagnostic device main body 11 calculates the vertical position of the car 4 based on the signal from the car position detector. Further, the diagnostic device main body 11 may directly acquire the vertical position information of the car 4 from the elevator control device 7.

The diagnostic device main body 11 stores a reference value for each position in the vertical direction of the car 4. Further, the diagnostic device main body 11 diagnoses the soundness of the diagnosis target after the occurrence of an earthquake based on the information from the state detector 29 and the position information. That is, the diagnostic device main body 11 determines the presence or absence of an abnormality by comparing the post-earthquake detection value with the reference value corresponding to the stop position of the car 4.

When the building 1 is deformed by the earthquake and the hoistway 3 is deformed, the horizontal position of the car 4 as seen from the state detector 29 deviates from the position before the earthquake. The determination unit 14 compares the horizontal position of the car 4 with the reference value to determine the presence or absence of an abnormality. Other configurations and operations are the same as those in the first embodiment.

Even with such a soundness diagnosis device, it is possible to diagnose the soundness of the diagnosis target after an earthquake with a compact configuration.

Further, by detecting the horizontal position of the car 4 with an optical detector, the soundness of the diagnosis target after the occurrence of an earthquake is diagnosed. Therefore, the configuration can be further made compact.

In addition, the soundness of the diagnosis target after the occurrence of an earthquake is diagnosed in consideration of the vertical position of the car 4. Therefore, more accurate diagnosis can be performed.

In the fourth embodiment, the state detector 29 is installed at the top of the hoistway 3, but it may be installed at the bottom or at both the top and the bottom.

Further, the elevating body that detects the position in the horizontal direction by the state detector 29 may be a balanced weight.

Further, the elevator equipment that detects the position in the horizontal direction by the state detector 29 does not have to be an elevating body.

Further, in the first to fourth embodiments, the diagnostic apparatus main body 11 automatically sets a reference value corresponding to a state value indicating the state of the elevator equipment before the occurrence of the earthquake. However, the reference value may be a threshold value of the state value set manually.

Embodiment 5.
Next, FIG. 7 is a configuration diagram showing a main part of the soundness diagnosis device according to the fifth embodiment of the present invention. The elevator equipment of the fifth embodiment is a hoistway 3.

The state detector 30 of the fifth embodiment detects the amount of deformation of the hoistway 3 in the horizontal direction as the state of the elevator equipment. Further, the state detector 30 has a rope to be detected 31, a detector main body 32, and a weight 33.

The rope to be detected 31 hangs vertically from the top of the hoistway 3 into the hoistway 3. The weight 33 is connected to the lower end of the rope to be detected 31. The detector main body 32 detects a change in the horizontal distance from the hoistway wall 3a to the rope to be detected 31.

Further, the detector main body 32 has a plurality of contact members 34. The contact members 34 are provided on the hoistway wall 3a at intervals in the vertical direction. Each contact member 34 has a fixing portion 34a and a ring-shaped facing portion 34b.

Each fixing portion 34a is fixed to the hoistway wall 3a. Each facing portion 34b surrounds the detected rope 31 and faces the detected rope 31.

FIG. 8 is a configuration diagram showing a main part of the state detector 30 of FIG. 7. A ring-shaped first contact portion 35 and a ring-shaped second contact portion 36 are provided on the inner peripheral surface of each of the facing portions 34b. The first contact portion 35 and the second contact portion 36 are arranged at intervals in the vertical direction. Further, the first contact portion 35 and the second contact portion 36 are made of a conductive material.

A conductor portion 37 is provided at a portion of the rope to be detected 31 facing the facing portion 34b. When the conductor portion 37 comes into contact with the inner peripheral surface of the facing portion 34b, a current flows between the first contact portion 35 and the second contact portion 36, and a signal is sent to the diagnostic apparatus main body 11.

After the occurrence of an earthquake, the diagnostic apparatus main body 11 diagnoses the soundness of the object to be diagnosed after the occurrence of the earthquake based on the contact state between the plurality of contact members 34 and the rope 31 to be detected. For example, when the diagnostic device main body 11 detects that at least one of the plurality of contact members 34 has come into contact with the rope to be detected 31, it determines that an abnormality has occurred in the diagnosis target. Other configurations and operations are the same as those in the first embodiment.

Even with such a soundness diagnosis device, it is possible to diagnose the soundness of the diagnosis target after an earthquake with a compact configuration.

Further, the detector main body 32 detects a change in the horizontal distance from the hoistway wall 3a to the rope to be detected 31. Therefore, even when the building 1 is deformed in a complicated manner, an abnormality can be detected.

All the contact members 34 may be connected in series or in parallel with the power supply.

Further, the detector main body 32 may be a sensor that does not detect contact with the rope to be detected 31 but generates a signal according to the horizontal distance to the rope to be detected 31. In this case, the diagnostic apparatus main body 11 may perform the soundness diagnosis by comparing the post-earthquake detection value and the reference value, or may perform the soundness diagnosis by comparing the post-earthquake detection value and the state threshold value.

Embodiment 6.
Next, FIG. 9 is a configuration diagram showing a main part of the soundness diagnosis device according to the sixth embodiment of the present invention. The elevator equipment of the sixth embodiment is a hoistway 3.

The rope to be detected 39 is vertically stretched in the hoistway 3. The guide members 40 are arranged in the hoistway 3 at intervals in the vertical direction. Further, each guide member 40 guides the rope 39 to be detected. Further, as each guide member 40, for example, a guide roller is used.

The rope to be detected 39 is provided with a cutting portion 42. The cut portion 42 is a portion that is cut when the rope to be detected 39 is stretched at a rope elongation threshold value or more. The cutting portion 42 can be composed of, for example, a pair of magnets that are attracted to each other. Further, the cut portion 42 can be configured by lowering the tensile strength of a part of the rope to be detected 39 to be lower than that of the other part.

The detector main body 41 detects the presence or absence of cutting of the cutting portion 42. Further, the detector main body 41 detects that the rope to be detected 39 is stretched at least the rope elongation threshold value by detecting the cutting of the cutting portion 42.

Further, the diagnostic device main body 11 determines that an abnormality has occurred in the diagnosis target when it is detected that the rope to be detected 39 is stretched at least the rope elongation threshold value after the occurrence of the earthquake. Other configurations and operations are the same as those in the first embodiment.

Even with such a soundness diagnosis device, it is possible to diagnose the soundness of the diagnosis target after an earthquake with a compact configuration.

Further, the detector main body 41 detects the elongation of the rope to be detected 39. Therefore, even when the building 1 is deformed in the vertical direction, an abnormality can be detected.

The detector main body 41 does not detect the disconnection of the rope to be detected 39, and may be a sensor that generates a signal according to the amount of elongation of the rope to be detected 39. In this case, the diagnostic apparatus main body 11 may perform the soundness diagnosis by comparing the post-earthquake detection value and the reference value, or may perform the soundness diagnosis by comparing the post-earthquake detection value and the state threshold value.

Further, the soundness diagnosis by the diagnostic device main body 11 of the first to sixth embodiments may be executed not by the signal from the earthquake detector 9 but by the input of a manual command.
