The drive unit 11 includes a drive motor 14, a drive belt 15, and a pair of link arms 16. The drive motor 14 is a device that generates a driving force for the opening operation of the pair of car door panels 10. The drive belt 15 and the pair of link arms 16 are portions that transmit the driving force generated by the drive motor 14. The drive belt 15 is, for example, an endless member wound around a pulley or the like attached to the rotation shaft of the drive motor 14. In this example, the drive belt 15 is wound so as to move downward to the opposite side in the left-right direction when moving to one side in the left-right direction in the upper side. One of the connecting arms 16 is attached to the left door panel. The other connecting arm 16 is mounted to the right door panel. One of the connection arms 16 is attached to the upper side of the drive belt 15. The other connecting arm 16 is attached to the lower side of the drive belt 15. As a result, the drive motor 14 rotates the rotary shaft, and the pair of car door panels 10 perform an opening operation.
The car door sill 12 is a portion that guides the opening operation of the pair of car door panels 10. The car door sill 12 is disposed at the lower end of the car doorway 8. The car door sill 12 is provided with a sill groove 17 for guiding the opening operation of the pair of car door panels 10. The sill groove 17 is a groove long in the left-right direction.
The door blade 13 is a plate-like member having a surface parallel to the vertical direction. The vane 13 is attached to one of the car door panels 10 so as to protrude from the hoistway 2 side toward the landing 3 side. The vane 13 is interlocked with the opening operation of the car door panel 10.
The elevator 1 is provided with a spot inspection system 18. The spot inspection system 18 is a system for performing spot inspection of the elevator 1. In this example, spot check system 18 is an internal system of elevator 1. Alternatively, spot check system 18 may be an external system of elevator 1. The spot inspection system 18 may be a system that is carried into the elevator 1 and applied at the time of spot inspection. In this case, the spot inspection system 18 may be a system that is removed from the elevator 1 after the spot inspection is completed. The spot inspection system 18 includes an imaging device 19 and a car-side block 20.
The imaging device 19 is a device that performs image capturing. The image captured by the imaging device 19 is a moving image, a still image, or the like. The imaging device 19 is disposed, for example, at the upper part of the car 6.
The car-side block 20 is a member attached to the car door 9. The car-side block 20 is attached to the car door 9 so as to protrude from the hoistway 2 side toward the landing 3 side. The car-side block 20 is interlocked with the opening operation of one of the car door panels 10. In this example, the car-side block 20 is mounted to the drive belt 15. Alternatively, the car-side block 20 may be attached to the connecting arm 16 connected to the car door panel 10 in conjunction with the opening operation.
Fig. 3 is a perspective view of the landing door 5 according to embodiment 1.
Fig. 3 shows a view of an arbitrary landing door 5. In this example, the landing doors 5 are similarly configured.
Each landing door 5 includes a pair of landing door plates 21, a link mechanism 22, a landing door sill 23, and a door lock 24.
The pair of landing door panels 21 are door panels that open and close at the landing entrance 4 of the floor corresponding to the landing door 5. One landing door panel 21 is provided on the left side when viewed from the hoistway 2 side. The other landing door panel 21 is provided on the right side when viewed from the hoistway 2 side. In the opening operation of the pair of landing door panels 21, the landing door panel 21 on the left side moves in parallel to the left side. In the opening operation of the pair of landing door panels 21, the landing door panel 21 on the right side moves in parallel to the right side. Here, the pair of landing door panels 21 are biased in the closing direction by a self-closing mechanism, not shown. Here, the self-closing mechanism applies a force to the pair of landing door panels 21 by using a passive mechanism using gravity, elastic force, or the like, for example.
When the car 6 stops at a stop position on any floor, each landing door plate 21 provided on the floor is opposed to any car door plate 10. At this time, the landing door plate 21 on the left side when viewed from the hoistway 2 side is opposed to the car door plate 10 on the left side when viewed from the inside of the car 6. The landing door plate 21 on the right side when viewed from the hoistway 2 side is opposed to the car door plate 10 on the right side when viewed from the inside of the car 6. Here, the stop position of each floor is a position of the car 6 where the floor height of the car 6 matches the floor height of the landing 3 of the floor.
The linkage mechanism 22 is a portion that links the pair of landing door panels 21. The linkage mechanism 22 is disposed above the landing doorway 4. The link mechanism 22 includes a link rope 25. The link rope 25 is, for example, a rope wound around pulleys or the like disposed on the left and right sides of the landing door 5. In this example, the link rope 25 is wound so as to move to the opposite side in the left-right direction from the lower side when moving to the one side in the left-right direction. One landing door panel 21 is attached to the upper side of the link rope 25. The other landing door panel 21 is attached to the lower side of the link rope 25. Thus, when one landing door panel 21 receives an external force to perform an opening operation, the other landing door 5 is interlocked with the opening operation by the interlock rope 25. Here, the landing door panel 21 that is opened by an external force is the landing door panel 21 on the driving side. The landing door panel 21 that performs an opening operation in conjunction with the driving-side landing door panel 21 is the driven-side landing door panel 21. The drive-side landing door panel 21 is an example of the 1 st landing door panel. The landing door panel 21 on the driven side is an example of a 2 nd landing door panel. The 1 st car door panel is a car door panel 10 that faces the 1 st landing door panel of any floor when the car 6 is stopped at the stop position of that floor. The 2 nd car door panel is a car door panel 10 that faces the 2 nd landing door panel of any floor when the car 6 is stopped at the stop position of that floor.
The landing door sill 23 is a portion that guides the opening motion of the pair of landing door panels 21. The landing sill 23 is disposed at the lower end of the landing doorway 4. The landing door sill 23 is provided with a sill groove 17 for guiding the opening operation of the pair of landing door panels 21. The sill groove 17 is a groove long in the left-right direction.
The door lock 24 is a part of the opening operation of the landing door plate 21 on the lock drive side. The door lock 24 includes a buckle 26, a hook 27, and a drive roller 28. A buckle 26 is fixed above the landing door panel 21. The hooks 27 are mounted to the landing door panel 21 on the driving side. When the car 6 is not at the stop position of the floor corresponding to the landing door 5, the hook 27 is hooked to the buckle 26. Thereby, the door lock 24 mechanically locks the opening operation of the landing door panel 21 on the driving side. The driving roller 28 is a portion to which an external force is applied to open the landing door panel 21. The drive roller 28 faces a surface parallel to the vertical direction of the vane 13 of the car door 9 when the car 6 stops at a stop position of a floor corresponding to the landing door 5.
The spot inspection system 18 includes a landing side block 29.
The landing side block 29 is a member attached to the landing door 5. The landing side block 29 is attached to the landing door 5 so as to protrude from the landing 3 side toward the hoistway 2 side. The landing side block 29 links the opening operation of the landing door plate 21 on the driven side.
Fig. 4 is a plan view of the elevator 1 according to embodiment 1.
Fig. 4 shows a view of the car 6 when it is stopped at a stop position on an arbitrary floor.
At this time, the vane 13 of the car door 9 is opposed to the drive roller 28 of the landing door 5. In normal operation, when the pair of car door panels 10 performs an opening operation, the vane 13 of the car door 9 contacts the drive roller 28 from the inner side in the lateral direction. When the door knife 13 is in contact with the drive roller 28, the hook 27 of the door lock 24 is disengaged from the catch 26. Thereby, the lock of the opening operation of the drive-side landing door panel 21 is released. Thereafter, the vane 13 of the car door 9 applies an external force to the landing door plate 21 on the driving side via the driving roller 28. The landing door plate 21 on the driving side is opened by an external force received from the vane 13 of the car door 9. At this time, the driven landing door panel 21 is opened by the link mechanism 22 in conjunction with the driving landing door panel 21.
The landing side block 29 protrudes toward the car 6 side. The terminal of the landing side block 29 on the car 6 side is disposed closer to the car 6 side than the terminal of the car side block 20 on the landing 3 side. In this example, the end of the landing side block 29 on the car 6 side protrudes toward the car 6 side to the same extent as the drive roller 28. The end of the car-side block 20 on the landing 3 side protrudes toward the landing 3 side to the same extent as the door blade 13. The landing side block 29 is disposed on the outer side in the lateral direction than the car side block 20.
Fig. 5 is an enlarged view of a main part of the elevator 1 according to embodiment 1.
Fig. 5 shows a diagram of the car door sill 12 and the landing door sill 23 at an arbitrary floor when the car 6 stops at the floor.
The car door sill 12 has a notch 30. The notch 30 of the car door sill 12 is provided at the following positions: when the car 6 passes through the floor provided with the landing door 5, the landing side block 29 provided to the landing door 5 passes through this position.
Landing sill 23 has a projection 31. The upper surface of the projection 31 is a flat surface. The shape of the protruding portion 31 of the landing door sill 23 is a shape that matches the notch 30 of the car door sill 12. When the car 6 stops at the stop position of the floor corresponding to the landing door 5, the protruding portion 31 of the landing door sill 23 blocks the notch 30 with a gap of such an extent that it does not come into contact with the edge of the notch 30 of the car door sill 12. Thereby, the opening to the hoistway 2 is closed when the car door 9 and the landing door 5 are opened.
Fig. 6 is a block diagram showing an example of the function of elevator 1 of embodiment 1.
The control panel 7 includes a control unit 32. The control unit 32 is a part that outputs a control command to the drive motor 14 of the car door 9, a traction machine, not shown, that drives the car 6, and the like. The control unit 32 outputs an opening command for opening the pair of car door panels 10 of the car door 9 to the drive motor 14 of the car door 9, for example.
The spot inspection system 18 includes a lock determination unit 33, a follow determination unit 34, and an estimation unit 35. In this example, the lock determination unit 33, the follow determination unit 34, and the estimation unit 35 are mounted on the control panel 7. Some or all of the lock determination unit 33, the follow determination unit 34, and the estimation unit 35 may be mounted on hardware outside the control panel 7.
The lock determination unit 33 is a unit that determines the state of locking of the door lock 24. The lock determination unit 33 determines the locked state from the image of the door lock 24 captured by the imaging device 19. The locked state includes, for example, information whether or not the lock has been made, whether or not the catch 26 and the hook 27 are in contact, whether or not the interval between the catch 26 and the hook 27 is in an appropriate range, or the like.
The follow-up determination unit 34 determines the follow-up of the opening command output from the control panel 7 by the door opening rate. The door opening rate is obtained by a sensor or the like provided in the car door 9, for example. The sensor provided to the car door 9 may be a sensor that detects the position of the door panel.
The estimating unit 35 is a part for estimating the abnormality occurrence site when an abnormality occurs in the spot inspection. The estimating unit 35 estimates the abnormality occurrence region using the determination results of the lock determining unit 33 and the follow-up determining unit 34.
The elevator 1 is provided with a communication device 36. The communication device 36 is connected to the spot inspection system 18 by wired communication, wireless communication, or the like so as to be able to accept input of a spot inspection result. The operator who performs the spot inspection operation of the elevator 1 holds the maintenance terminal 37. The maintenance terminal 37 is a removable information terminal. The maintenance terminal 37 is connected to the communication device 36, for example, by wireless communication, in such a manner that an operator can confirm the spot inspection result of the spot inspection system 18 through the communication device 36.
Next, an example of spot inspection by the spot inspection system 18 of the elevator 1 will be described with reference to fig. 7 to 9.
Fig. 7 is a side view of the car 6 of embodiment 1.
Fig. 8 is a diagram showing an example of an image captured by the imaging device 19 according to embodiment 1.
Fig. 9 is a table showing an example of the abnormality occurrence region estimation performed by the estimation unit 35 of embodiment 1.
Fig. 7 shows an example of the spot inspection of the landing door 5 performed at any floor.
The control unit 32 automatically moves the car 6 to a spot position of a floor where spot detection of the landing door 5 is performed. Here, the spot position of each floor is the position of the car 6 where the door lock 24 enters the range of the imaging device 19 of the spot system 18. The landing side block 29 is disposed at a position facing the car side block 20 in the lateral direction. Here, the vane 13 of the car door 9 and the drive roller 28 of the landing door 5 do not face each other when the car 6 is in the spot position.
The control section 32 inputs an opening instruction to the drive motor 14. At this time, the drive motor 14 transmits a drive force to the pair of car door panels 10 via the drive belt 15. Since the vane 13 and the drive roller 28 do not face each other, the car door panel 10 facing the landing door panel 21 on the drive side does not apply an external force to the landing door panel 21. On the other hand, since the car-side block 20 and the landing-side block 29 face each other, the car door panel 10 facing the driven-side landing door panel 21 applies an external force in the opening direction to the driven-side landing door panel 21 via the car-side block 20 and the landing-side block 29. At this time, the linkage mechanism 22 applies an external force in the opening direction to the landing door panel 21 on the driving side so as to link the landing door panel 21 on the driven side. Here, since the car 6 is not stopped at the stop position of the floor where the landing door 5 is provided, the door lock 24 mechanically locks the opening operation of the landing door plate 21 on the driving side. Therefore, when the lock mechanism is activated by the contact between the hook 27 and the hasp 26 of the door lock 24, and the pair of landing door panels 21 does not perform the opening operation irrespective of the input opening instruction, the spot check system 18 can determine that the landing door 5 is not abnormal.
Fig. 8 shows an example of an image of the door lock 24 captured by the imaging device 19.
The lock determination unit 33 measures gap sizes G1 and G2 between the hook 27 and the buckle 26, for example, from an image captured by the imaging device 19. The lock determination unit 33 determines the locked state based on the measured gap sizes G1 and G2. The lock determination unit 33 determines that the lock mechanism is activated by the contact between the hook 27 and the buckle 26, for example, when at least one of the measured gap sizes is 0.
Fig. 9 shows an example of the determination performed by the spot check system 18.
The fact that the lock mechanism is activated due to the contact between the catch 26 and the hook 27 is determined based on the state of locking determined by the lock determination unit 33. When the pair of landing door panels 21 does not perform the opening operation irrespective of the opening instruction, the door opening rate determined by the follow-up determination unit 34 is determined based on whether or not the door opening rate follows the opening instruction. Therefore, when the lock determination unit 33 determines that the hook 27 is in contact with the hook 26 and the follow-up determination unit 34 determines that the door opening rate does not follow the open command, the spot check system 18 determines that there is no failure site.
On the other hand, when the lock determination unit 33 determines that the hook 27 is in contact with the hook 26 and the follow determination unit 34 determines that the door opening rate follows the open command, the estimation unit 35 estimates that there is an abnormality in the drive motor 14 or the link mechanism 22.
When the lock determination unit 33 determines that the hook 27 is not in contact with the hook 26 and the follow determination unit 34 determines that the door opening rate does not follow the open command, the estimation unit 35 estimates that there is an abnormality in the linkage mechanism 22, the car-side block 20, the landing-side block 29, or the door lock 24. For example, when there is an abnormality in the door lock 24, the hook 27 is not hooked to the buckle 26, and an abnormality occurs in the link mechanism 22, such an abnormality may occur.
When the lock determination unit 33 determines that the hook 27 is not in contact with the hook 26 and the follow determination unit 34 determines that the door opening rate follows the open command, the estimation unit 35 estimates that there is an abnormality in the car-side block 20, the landing-side block 29, or the door lock 24. For example, when the door lock 24 is abnormal, the hook 27 is not hooked to the buckle 26, and the link mechanism 22 is normal, such an abnormality may occur.
Further, in the case where the lock determination unit 33 determines that the hook 27 and the buckle 26 are in contact before the opening command is output to the drive motor 14, the estimation unit 35 estimates that there is an abnormality in the sill groove 17 or the door lock 24. Such an abnormality may occur, for example, when foreign matter is present in the sill groove 17 and the hook 26 and the hook 27 are always in contact.
As described above, the elevator 1 including the spot inspection system 18 of embodiment 1 includes the car door 9 and the landing door 5. The car door 9 is provided at a car doorway 8 of the car 6. The car door 9 includes a pair of car door panels 10 and a drive motor 14. The drive motor 14 generates a drive force for opening the pair of car door panels 10 in response to the input opening command. The landing door 5 is provided at the landing entrance 4 of the landing 3 of the corresponding floor. The landing door 5 includes a landing door plate 21 on the driving side, a landing door plate 21 on the driven side, and a door lock 24. The landing door plate 21 on the driving side faces one of the car door plates 10 when the car 6 is stopped at the stop position of the corresponding floor, and is interlocked with the opening operation of the car door plate 10. The driven landing door plate 21 is opposed to the other car door plate 10 when the car 6 is stopped at the stop position of the corresponding floor, and is interlocked with the opening operation of the driving landing door plate 21. The door lock 24 is provided on the landing door plate 21 on the driving side. The door lock 24 locks the opening operation of the landing door plate 21 on the drive side when the car 6 is not in the stop position. The spot inspection system 18 of the elevator 1 includes a car-side block 20, a lock determination unit 33, a landing-side block 29, and a follow determination unit 34. The car-side block 20 is provided at the car door 9 so as to protrude from the hoistway 2 side toward the landing 3 side. The car-side block 20 is interlocked with the opening operation of one of the car door panels 10 facing the hall door panel 21 on the driven side. The lock determination unit 33 determines the state of locking of the door lock 24 when the car 6 is located at a different spot position from the stop position of the floor corresponding to the landing door 5. The landing side block 29 is provided at the landing door 5 so as to protrude from the landing 3 side toward the hoistway 2 side. The landing side block 29 is linked with the landing door plate 21 on the driven side. The landing side block 29 is arranged at the following positions: when the car 6 is located at the spot inspection position, if the car-side block 20 is interlocked with the opening operation of the car door panel 10, a force in the direction of opening the landing door panel 21 on the driven side is received from the car-side block 20 at this position. The follow-up determination unit 34 determines whether or not the opening operation of the pair of car door panels 10 follows the opening command.
According to this configuration, the coordinated spot inspection of the pair of landing door plates 21 of the landing door 5, the spot inspection of the door lock 24, the spot inspection of the drive motor 14 of the car door 9, and the spot inspection of the linkage of the drive belt 15 and the pair of car door plates 10 are performed simultaneously. Further, since spot inspection is performed by the force applied by the drive motor 14 of the car door 9, the manual work of the operator can be reduced. Thus, the spot inspection efficiency is not easily lowered. In addition, remote spot inspection is made possible. Further, by attaching the car-side block 20 to the connecting arm, the addition of components can be suppressed by using existing components.
The spot inspection system 18 further includes an imaging device 19. The imaging device 19 is provided in the car 6. The imaging device 19 images the door lock 24 when the car 6 is at the spot position. The lock determination unit 33 determines the state of locking of the door lock 24 based on the image captured by the imaging device 19.
With this configuration, the measurement work for measuring the gap between the hook 26 and the hook 27 by the operator is not required. Thus, the spot inspection efficiency is less likely to be lowered.
The spot inspection system 18 further includes an estimating unit 35. The estimating unit 35 estimates the abnormality occurrence region based on the determination result of the lock determining unit 33 and the determination result of the follow-up determining unit 34.
According to such a configuration, when an abnormality occurs, the operator can easily grasp the site where the abnormality occurs, and therefore the work efficiency of the maintenance work becomes higher.
In the elevator 1, the car door 9 includes a car door sill 12 that guides the opening and closing of the pair of car door panels 10. The car door sill 12 is provided with a notch 30 through which the landing side block 29 passes when the car 6 passes through the floor corresponding to the landing door 5. The landing door 5 has a landing door sill 23 that guides the opening and closing of a pair of landing door panels 21. The landing door sill 23 is provided with a projection 31 that blocks the notch 30 when the car 6 is stopped at the stop position.
In addition, a notch 30 may be provided in the landing door sill 23 through which the car side block 20 passes when the car 6 passes through the floor corresponding to the landing door 5. At this time, the car door sill 12 is provided with a projection 31 that blocks the notch 30 when the car 6 is stopped at the stop position.
According to this configuration, the elevator 1 can perform normal operation with the landing side block 29 and the car side block 20 attached by the notch 30 provided in the car door sill 12 or the landing door sill 23. Therefore, the post-operation of the spot inspection operation becomes simple. Therefore, the work efficiency of the maintenance work becomes higher.
The control panel 7 of the elevator 1 stops the car 6 at the checking position.
This allows the position of the car 6 to be automatically aligned with the spot inspection position, and thus the maintenance work becomes more efficient.
Next, an example of the hardware configuration of the elevator 1 will be described with reference to fig. 10.
Fig. 10 is a hardware configuration diagram of a main part of elevator 1 according to embodiment 1.
The functions of the elevator 1 including the spot check system 18 can be implemented by a processing circuit. The processing circuit is provided with at least one processor 100a and at least one memory 100b. The processing circuit may include the processor 100a and the memory 100b, or may include at least one dedicated hardware 200 instead of these.
In the case where the processing circuit is provided with a processor 100a and a memory 100b, the functions of the elevator 1 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 100b. The processor 100a reads out and executes a program stored in the memory 100b to realize the functions of the elevator 1.
The processor 100a is also called a CPU (Central Processing Unit: central processing unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 100b is configured by a nonvolatile or volatile semiconductor memory such as a RAM (random access memory), a ROM (read only memory), a flash memory, an EPROM (erasable programmable read only memory), an EEPROM (electrically erasable programmable read only memory), or the like.
In the case of processing circuitry provided with dedicated hardware 200, the processing circuitry is implemented, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.
The functions of the elevator 1 can be implemented by means of a processing circuit, respectively. Alternatively, the functions of the elevator 1 may be realized collectively by a processing circuit. Regarding the functions of the elevator 1, one part may also be implemented by means of dedicated hardware 200 and the other part by means of software or firmware. Thus, the processing circuit implements the functions of the elevator 1 by means of dedicated hardware 200, software, firmware or a combination thereof.
