Detailed Description
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 diagnosis apparatus according to embodiment 1 of the present invention. In the figure, a building 1 is provided with an elevator 2. The elevator 2 includes a hoistway 3, a car 4, a counterweight not shown, a hoisting machine 5, a suspension body 6, and an elevator control device 7.
The car 4 and the counterweight are suspended in the hoistway 3 by a suspension 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 in the ceiling portion of the hoistway 3. The hoisting machine 5 includes a drive sheave 8, a motor not shown, and a brake not shown. The motor rotates the drive sheave 8. The brake holds the drive sheave 8 in a stationary state 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 counterweight are raised and lowered in the hoistway 3 by the rotation of the drive sheave 8. The elevator control device 7 controls the operation of the car 4.
The building 1 is provided with a seismic detector 9 and a state detector 10. 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 corresponding to the state of the elevator apparatus. The signal from the seismic detector 9 and the signal from the state detector 10 are input to the diagnostic apparatus main body 11.
The soundness diagnostic device according to embodiment 1 includes a state detector 10 and a diagnostic device main body 11. The diagnostic device main body 11 diagnoses the soundness of the diagnostic object after the occurrence of the earthquake, the diagnostic object being at least one of the building 1 and the elevator 2, using the information from the state detector 10.
The diagnostic device main body 11 of embodiment 1 determines whether or not there is an abnormality that is an obstacle to restarting the automatic operation of the elevator 2 as soundness of a diagnostic target after an earthquake occurs.
The diagnostic apparatus main body 11 includes 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 a state of the elevator apparatus before occurrence of an earthquake.
The determination unit 14 compares a post-earthquake detection value, which is a state value indicating the state of the elevator apparatus after the occurrence of the earthquake, with a reference value to determine whether or not there is an abnormality in the diagnostic target after the occurrence of the earthquake.
The reference value is, for example, a state value before occurrence of an earthquake or a value obtained by adding an allowable value to the state value before occurrence of the earthquake. When the state value before the occurrence of the earthquake is set as the reference value, the determination unit 14 determines that there is an abnormality when the difference between the reference value and the post-earthquake detected value exceeds the allowable value. When a value obtained by adding an allowable value to the state value before the occurrence of an earthquake is used as a 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 time of acquiring the information from the state detector 10.
Fig. 2 is a flowchart showing the operation of the diagnostic device main body 11 of fig. 1. The diagnostic device main body 11 periodically executes the processing of fig. 2 in a set cycle. First, in step S1, the diagnostic device body 11 checks whether or not an earthquake of a set magnitude or more has been detected by the earthquake detector 9.
If an earthquake is not detected, the diagnostic device main body 11 acquires information from the state detector 10 in step S2. Then, the diagnostic device main body 11 updates the reference value in step S3, and ends the processing of this time.
When an earthquake is detected, the diagnostic device main body 11 confirms whether or not the shake has subsided from the information from the earthquake detector 9 in step S4. If the shaking has not subsided, the diagnostic apparatus main body 11 ends the processing of this time.
When the fluctuation has subsided, the diagnostic apparatus main body confirms whether or not the set time has elapsed in step S5. If the set time has not elapsed, the diagnostic device main body 11 ends the processing of this time.
When the set time has elapsed, the diagnostic device main body 11 acquires information from the state detector 10 in step S6. Then, the diagnostic device main body 11 determines whether or not there is an abnormality in the diagnostic object in step S7. Next, in step S8, the diagnostic device body 11 outputs the determination result to the elevator control device 7 and the remote management room, and ends the processing.
Fig. 3 is a block diagram illustrating an installation state of the state detector 10 of fig. 1. The elevator apparatus of embodiment 1 is a guide rail 21. The guide rail 21 is provided in the hoistway 3 in the vertical direction. In addition, the guide rail 21 guides the raising and lowering of the car 4 or the counterweight.
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 up-down direction. The lower end of the guide rail 21 is also separated from the bottom surface of the hoistway 3 in a normal state.
The state detector 10 of embodiment 1 detects the position of the lower end of the guide rail 21 in the vertical direction as the state of the elevator apparatus. That is, the state detector 10 of embodiment 1 is a displacement detector.
When the building 1 is deformed by an earthquake, for example, the hoistway wall 3a is deformed from the broken line state to the solid line state in fig. 3, the guide rail 21 is also deformed. The lower end of the guide rail 21 is displaced upward. The determination unit 14 compares the position of the lower end of the guide rail 21 with a reference value to determine whether or not there is an abnormality in the diagnostic target after the occurrence of an earthquake.
In such a soundness diagnosis apparatus, a state detector 10 that detects the state of the elevator equipment is provided in the elevator 2. Then, the soundness of the diagnostic object after the occurrence of the earthquake is diagnosed using the information from the state detector 10. Therefore, the soundness of the object to be diagnosed after the occurrence of the earthquake can be diagnosed with a compact configuration.
The diagnostic device body 11 compares the post-earthquake state value with a reference value to determine whether or not there is an abnormality in the diagnostic target after the occurrence of an earthquake. Therefore, the soundness of the diagnostic object after the occurrence of the earthquake can be diagnosed more accurately.
The diagnostic device body 11 periodically acquires information from the state detector 10 and periodically updates the reference value. Therefore, the temporal change can be removed, and the damage due to the earthquake can be estimated more accurately.
The state detector 10 is a displacement detector that detects the position of the lower end of the guide rail 21. Therefore, the structure can be further compact.
In addition, a mechanical switch operated by displacement of the lower end of the guide rail 21 may also be used as the state detector 10.
Further, the lower end of the guide rail 21 may be lowered by contraction due to an earthquake of the building 1. Therefore, the reference value in the case where the lower end of the guide rail 21 is lowered may be set.
Further, the positions of the lower ends of the two or more guide rails 21 may be detected using two or more state detectors 10.
In the above example, the reference value and the post-earthquake detection value are compared, but the change amount of the state value within the set time may be compared with the change amount threshold value, and it may be determined that there is an abnormality when the change amount exceeds the change amount threshold value.
Embodiment 2.
Next, fig. 4 is a configuration diagram showing a main part of the soundness diagnosis apparatus according to embodiment 2 of the present invention. The elevator apparatus of embodiment 2 is a governor rope tension pulley 23. The governor rope tension pulley 23 is provided at a lower portion of the hoistway 3.
The governor rope tension sheave 23 is guided by a tension sheave guide device, not shown, and is movable in the vertical direction. Further, the movement of the governor rope tension sheave 23 in the horizontal direction is restricted by the tension sheave guide device.
A speed limiter 24 is provided in an upper portion of the hoistway 3. Governor 24 has a governor sheave 25. A governor rope 26 is wound around the governor sheave 25 and the governor rope tension sheave 23. The governor rope 26 is annularly arranged in the hoistway 3.
The state detector 27 of embodiment 2 detects the position of the governor rope tension pulley 23 in the vertical direction as the state of the elevator equipment. That is, the state detector 27 of embodiment 2 is a displacement detector.
When building 1 is deformed by an earthquake, for example, and hoistway 3 is deformed as shown in fig. 4, governor 24 is horizontally displaced from the position of the broken line to the position of the solid line. This displaces the governor rope tension pulley 23 upward. The determination unit 14 compares the position of the governor rope tension pulley 23 with a reference value, and determines whether or not there is an abnormality in the diagnostic target after the occurrence of an earthquake. Other structures and operations are the same as those of embodiment 1.
In such a soundness diagnosis apparatus, soundness of a diagnosis target after an earthquake occurs can be diagnosed with a compact configuration.
The soundness of the subject of diagnosis after the occurrence of the earthquake is diagnosed based on the amount of rise of the governor rope tension sheave 23 corresponding to the deformation of the building 1. Therefore, the structure can be further compact.
Further, a mechanical switch operated by displacement of the governor rope tension sheave 23 may be used as the state detector 27.
In addition, the time damper rope tensioner 23 may extremely descend due to contraction of the building 1 caused by an earthquake. Therefore, the reference value in the case where the governor rope tension sheave 23 is lowered may be set.
In the above example, the reference value and the post-earthquake detection value are compared, but the change amount of the state value within the set time may be compared with the change amount threshold value, and it may be determined that there is an abnormality when the change amount exceeds the change amount threshold value.
Next, fig. 5 is a configuration diagram showing a main part of a soundness diagnosis apparatus according to embodiment 3 of the present invention. The elevator apparatus of embodiment 3 is the guide rail bracket 22. In embodiment 3, a plurality of state detectors 28 are used. Each state detector 28 is provided to the corresponding rail bracket 22.
Each state detector 28 of embodiment 3 detects deformation of the corresponding guide rail bracket 22 as the state of the elevator apparatus. That is, each state detector 28 of embodiment 3 is a deformation detector. Examples of the strain detector include a strain gauge.
The diagnostic device main body 11 compares the sum of the deformation amounts detected by all the state detectors 28 with a reference value to determine the presence or absence of an abnormality. The diagnostic device main body 11 may determine the presence or absence of an abnormality by comparing the maximum value of the deformation amounts detected by all the state detectors 28 with a reference value. Other structures and operations are the same as those of embodiment 1.
In such a soundness diagnosis apparatus, soundness of a diagnosis target after an earthquake occurs can be diagnosed with a compact configuration.
Further, since the presence or absence of an abnormality of the diagnostic object is determined based on the amount of deformation of the rail bracket 22, the configuration can be further made compact.
Further, by providing the state detector 28 in two or more of the rail brackets 22, diagnosis with higher accuracy can be performed.
The state detector 28 provided in the guide rail brackets 22 is not particularly limited.
Next, fig. 6 is a configuration diagram showing a main part of a soundness diagnosis apparatus according to embodiment 4 of the present invention. The elevator apparatus according to embodiment 4 is a car 4 as an elevating body.
The state detector 29 according to embodiment 4 is provided at the top of the hoistway 3. Further, the state detector 29 of embodiment 4 detects the position of the car 4 in the horizontal direction as the state of the elevator apparatus. As the state detector 29 of embodiment 4, an optical detector, for example, an imaging device is used.
After the earthquake occurs, the car 4 stops. The diagnosis device main body 11 of embodiment 4 acquires the position information of the car 4 in the vertical direction from the elevator 2 after the occurrence of the earthquake.
The acquired position information is, for example, a signal from a car position detector provided in the hoisting machine 5. In this case, the diagnosis device main body 11 calculates the position of the car 4 in the vertical direction based on the signal from the car position detector. The diagnostic device main body 11 may directly acquire the position information of the car 4 in the vertical direction from the elevator control device 7.
The diagnostic device main body 11 stores a reference value for each position of the car 4 in the vertical direction. The diagnostic apparatus main body 11 diagnoses the soundness of the diagnostic object after the occurrence of the earthquake based on the information and the position information from the state detector 29. That is, the diagnosis device body 11 compares the post-earthquake detected value with a reference value corresponding to the stop position of the car 4 to determine whether or not there is an abnormality.
When the building 1 is deformed by an earthquake and the hoistway 3 is deformed, the position of the car 4 in the horizontal direction as viewed from the state detector 29 is deviated from the position before the earthquake. The determination unit 14 compares the position of the car 4 in the horizontal direction with a reference value to determine the presence or absence of an abnormality. Other structures and operations are the same as those of embodiment 1.
In such a soundness diagnosis apparatus, soundness of a diagnosis target after an earthquake occurs can be diagnosed with a compact configuration.
Further, the position of the car 4 in the horizontal direction is detected by an optical detector, whereby the soundness of the diagnosis target after the occurrence of the earthquake is diagnosed. Therefore, the structure can be further compact.
In addition, the soundness of the diagnosis target after the occurrence of the earthquake is diagnosed in consideration of the position of the car 4 in the vertical direction. Therefore, more accurate diagnosis can be performed.
In embodiment 4, the state detector 29 is provided at the top of the hoistway 3, but may be provided at the bottom, or may be provided at both the top and the bottom.
The lifting body for detecting the position in the horizontal direction by the state detector 29 may be a counterweight.
The elevator equipment for detecting the position in the horizontal direction by the state detector 29 may not be a vertically movable body.
In embodiments 1 to 4, the diagnostic device body 11 automatically sets a reference value corresponding to a state value indicating a state of the elevator apparatus before the occurrence of the earthquake. However, the reference value may be a threshold value of a state value set manually.
Next, fig. 7 is a configuration diagram showing a main part of a soundness diagnosis apparatus according to embodiment 5 of the present invention. The elevator apparatus according to embodiment 5 is a hoistway 3.
The state detector 30 of embodiment 5 detects the amount of deformation of the hoistway 3 in the horizontal direction as the state of the elevator equipment. The state detector 30 includes a rope 31 to be detected, a detector main body 32, and a weight 33.
The rope 31 to be detected vertically hangs from the top of the hoistway 3 into the hoistway 3. The weight 33 is connected to the lower end of the rope 31 to be detected. The detector main body 32 detects a change in the horizontal distance from the hoistway wall 3a to the detected rope 31.
Further, the detector body 32 has a plurality of contact members 34. The contact members 34 are provided on the well wall 3a at intervals in the vertical direction. Each contact member 34 has a fixed portion 34a and an annular facing portion 34 b.
Each fixing portion 34a is fixed to the hoistway wall 3 a. Each of the opposing portions 34b surrounds the detection rope 31 and faces the detection rope 31.
Fig. 8 is a block diagram showing a main part of the state detector 30 of fig. 7. An annular 1 st contact portion 35 and an annular 2 nd contact portion 36 are provided on the inner peripheral surface of each of the opposing portions 34 b. The 1 st contact portion 35 and the 2 nd contact portion 36 are arranged at an interval from each other in the vertical direction. The 1 st contact portion 35 and the 2 nd contact portion 36 are made of a conductive material.
A conductor portion 37 is provided at a portion of the detection rope 31 facing the facing portion 34 b. When the conductor portion 37 comes into contact with the inner peripheral surface of the opposing portion 34b, a current flows between the 1 st contact portion 35 and the 2 nd contact portion 36, and a signal is transmitted to the diagnostic device main body 11.
The diagnostic device main body 11 diagnoses the soundness of the diagnostic object 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 after the occurrence of the earthquake. For example, when the diagnostic device body 11 detects that at least one of the contact members 34 has come into contact with the rope 31 to be detected, it is determined that an abnormality has occurred in the object to be diagnosed. Other structures and operations are the same as those of embodiment 1.
In such a soundness diagnosis apparatus, soundness of a diagnosis target after an earthquake occurs can be diagnosed 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 31 to be detected. Therefore, even when the building 1 is deformed in a complicated manner, the abnormality can be detected.
All the contact members 34 may be connected in series with the power supply, or may be connected in parallel.
The detector main body 32 may be a sensor that generates a signal corresponding to a horizontal distance from the rope 31 to be detected, instead of detecting contact with the rope 31 to be detected. In this case, the diagnostic device body 11 may perform the soundness diagnosis by comparing the post-earthquake detected value with the reference value, or may perform the soundness diagnosis by comparing the post-earthquake detected value with the state threshold value.
Next, fig. 9 is a configuration diagram showing a main part of a soundness diagnosis apparatus according to embodiment 6 of the present invention. The elevator apparatus according to embodiment 6 is a hoistway 3.
The state detector 38 according to embodiment 6 detects the amount of deformation of the hoistway 3 in the vertical direction as the state of the elevator apparatus. The state detector 38 includes a rope 39 to be detected, a plurality of pairs of guide members 40, and a detector main body 41.
The rope to be detected 39 extends vertically in the hoistway 3. The guide members 40 are disposed in the hoistway 3 at a vertical distance from each other. 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 39 to be detected is provided with a cutting portion 42. The cutting section 42 is a portion that is cut when the detected rope 39 undergoes elongation equal to or greater than a rope elongation threshold. The cutting portion 42 may be formed of a pair of magnets attracted to each other, for example. The cutting portion 42 may be configured by making a part of the rope 39 to be detected lower in tensile strength than the other parts.
The detector body 41 detects whether or not the cutting section 42 is cut. The detector body 41 detects that the rope 39 to be detected is elongated by a rope elongation threshold value or more by detecting the cutting of the cutting portion 42.
When the detection rope 39 is elongated by a rope elongation threshold value or more after the occurrence of an earthquake, the diagnostic device body 11 determines that an abnormality has occurred in the object to be diagnosed. Other structures and operations are the same as those of embodiment 1.
In such a soundness diagnosis apparatus, soundness of a diagnosis target after an earthquake occurs can be diagnosed with a compact configuration.
Further, the detector main body 41 detects the elongation of the rope 39 to be detected. Therefore, even when the building 1 is deformed in the vertical direction, the abnormality can be detected.
The detector main body 41 may be a sensor that generates a signal corresponding to the elongation of the detection rope 39, instead of detecting the cutting of the detection rope 39. In this case, the diagnostic device body 11 may perform the soundness diagnosis by comparing the post-earthquake detected value with the reference value, or may perform the soundness diagnosis by comparing the post-earthquake detected value with the state threshold value.
Note that the soundness diagnosis performed by the diagnostic device main bodies 11 according to embodiments 1 to 6 may be performed by manually inputting a command, regardless of the signal from the seismic detector 9.
In addition, the setting and updating of the reference values in embodiments 1 to 6 may be performed manually.
