Description

  The present invention relates to an elevator inspection apparatus suitable for inspecting a situation in a hoistway of an elevator car after an earthquake occurs.

  In general, in order to protect the safety of users (passengers) in the event of an earthquake, an elevator is installed with an earthquake control operation device that stops the elevator (climbing operation of the car) when an earthquake shake is detected. When the seismometer installed in the machine room or tower detects a certain amount of shaking, this earthquake control operation device stops the elevator car at the nearest floor, opens the door, and evacuates to the stop floor. This ensures the safety of users. The earthquake detected by the control device during earthquakes is the initial tremor and the main tremor. When only the initial tremor is detected, the elevator operation (elevating and lowering the car) is automatically restored after a certain period of time. When the main motion of strong shaking is detected, the elevator operation is stopped, and then the elevator operation is not restored until a repair inspection is performed by a local inspection manager.

  The inspection manager can confirm that the elevator equipment is damaged or damaged visually at the site, operate the elevator, perform diagnostic operation, and restore the elevator if it can be confirmed that the elevator can be operated normally. For example, if the elevator does not operate normally due to the rope being disconnected or caught, or the guide rail is tilted, and if the cause cannot be identified, an inspection work for identifying the cause is required. However, it is difficult to confirm the state of the entire hoistway with the elevator stopped, and in particular, in the case of a high-rise elevator with a long hoistway, the confirmation work is extremely difficult.

  Therefore, even when the confirmation work is difficult in this way, a technique for inspecting the elevator has been proposed.For example, even when the car is stopped, such as during restoration work after an earthquake, Further, there is an “elevator inspection device” (see Patent Document 1) that can quickly inspect the entire length of the hoistway.

JP 2011-98806 A

  The technology according to Patent Document 1 described above is an inspection device having a configuration in which an imaging device that images the inside of a hoistway is connected to a drive device that moves a guide rail sandwiched between wheels, and performs an inspection for restoration after the occurrence of an earthquake. When carrying out, the drive device is moved along the guide rail, and the image in the hoistway is acquired and inspected by the imaging device. Since a drive unit that moves between wheels is used, if the guide rail itself becomes dislodged or tilted due to strong earthquake shaking, the drive unit will not move at the corresponding location, and inspection after the applicable location will occur. Cannot be performed, and the inspection cannot be continued over the entire length of the intended hoistway. There is a drawback that a high sex.

  In addition, when the guide rail itself has a problem of disengagement or tilting, the car can run because the car roller or shoe is in contact with the guide rail even if the elevator is operated. Similarly, even if the rope is disconnected or caught, the car cannot be run, and if it is forced to move, there is a high possibility that the elevator equipment will be damaged. It is safer not to move.

  In this way, in the situation where the guide rail itself has become disconnected or tilted, or the rope has come off or caught, a check inspection is carried out by the inspection manager to identify the cause on site. However, inspecting the inside of the hoistway with the elevator stopped is particularly difficult for high-rise elevators with a long hoistway, not only requiring much time to identify the cause, but also an aftershock occurred during inspection work In some cases, there is a risk that the elevator equipment will fall, so there is a problem with safety, and the time, mental, and physical burden on the inspection manager is extremely large.

  The present invention has been made to solve such problems, and its technical problem is that the elevator can be quickly and accurately placed in the hoistway regardless of the length of the hoistway even if the elevator stops and cannot move. It is providing the elevator inspection apparatus which can check the elevator apparatus in Easily.

In order to solve the above technical problem, the present invention is an elevator inspection device for inspecting elevator equipment in a hoistway in a state where an elevator car is stopped , and exists in the hoistway from itself. A distance measuring means for measuring a distance to an object that becomes an obstacle, and a function of keeping the distance to the object at a predetermined distance by moving itself in a horizontal direction based on distance information from the distance measuring means the a, a flight vehicle having a function to fly by raising or lowering the air of the hoistway without contacting to the object that becomes an obstacle including the elevator devices installed in the hoistway, Imaging means having a function of imaging the elevator apparatus attached to the flying means and installed in the hoistway.

  According to the elevator inspection apparatus of the present invention, the imaging means attached to the flying means that ascends or descends and flies in a contactless manner with an object including an elevator device in the hoistway where the car ascends and descends. Has a function to image the elevator equipment installed in the hoistway, so even if the elevator stops and cannot be moved due to the occurrence of a strong shaking earthquake, an inspection manager with local expertise performs inspection work for restoration When doing, if you refer to the imaging information taken by the imaging means while throwing the device into the hoistway and moving it up and down by the flight means, you can accurately grasp the status of the elevator equipment installed in the hoistway, As a result, the elevator equipment in the hoistway can be simply inspected quickly and accurately regardless of the length of the hoistway, and the elevator can be restored early.

  The elevator inspection apparatus according to the present invention will be described below in detail with reference to the drawings, with some examples.

  FIG. 1 is a perspective view illustrating a schematic structure of an elevator 1 to be inspected by an elevator inspection apparatus according to the present invention, with a main portion seen through. This elevator 1 moves up and down between a landing 4 (only the lowest floor is shown in FIG. 1) in which a car 3 is installed on each floor in a hoistway 2 provided in the building. 2 is provided with a pit 5, and a machine room 6 is provided above the hoistway 2. The car 3 moves up and down along a car guide rail 7 erected on the wall of the hoistway 2, and is moved by a main rope 13 through a hoisting machine 14 schematically showing a main body installed in the machine room 6. Similarly, the counterweight 8 attached to the hoistway 3 moves up and down along a weight guide rail 9 erected on the wall of the hoistway 2. The machine room 6 is provided with a control panel 12 for controlling the raising / lowering operation of the car 3, and a main rope 13 is hung on a hoisting machine 14 for raising and lowering the car 3. Is attached to the car 3 and the other end is attached to the counterweight 8.

Extending in the height direction in the hoistway 2.

  In the elevator 1, the car 3 is moved up and down by driving the hoisting machine 14, but a landing door (also referred to as an outer door) 10 provided in the landing 4 on each floor serves as an entrance for the passenger car 3. The landing door 10 engages with a car door (also referred to as an inner door) 11 of the car 3 when the car 3 is landed, and the user can get on and off the car 3 by opening and closing. Incidentally, the maintenance inspector can open the landing door 10 by the external opening means during the maintenance inspection work and inspect the inside of the hoistway 2. Even when the elevator is stopped and cannot be moved, the inspection door, which will be described later, is entered into the hoistway 2 by opening the landing door 10 when performing inspection work for restoration on site. Is possible. Such an inspection device is provided in the machine room 6 or pit 5 in the ceiling of the hoistway 2 so that the inspection can be started immediately after a strong earthquake occurs and the elevator stops even if the inspection manager does not bring the device. It is preferable to permanently install it on the floor, or to permanently install it on or under the car in the car 3. For example, when the inspection device is installed in the machine room 6, an inspection hole may be drilled in the floor of the machine room 6, and the inspection hole may be inserted into the hoistway 2. In any case, the inspection device is applicable to not only the elevator 1 when the car 3 is one system as described in FIG. 1 but also a multi-system elevator where a plurality of cars 3 are arranged in parallel. Is possible.

  FIG. 2 is a perspective view showing a part of the basic configuration of the elevator inspection apparatus 20 according to the first embodiment. FIG. 3 is an external view of the inspection device 20 as viewed from the top direction, showing the positional relationship between the car guide rail 7 and the main rope 13 in the hoistway 2 during flight. This inspection device 20 is for inspecting elevator equipment in the hoistway 2 in a state where the elevator car 3 is stopped. Even if a strong shaking earthquake occurs and the elevator stops and cannot be moved, When an inspection manager with specialized technology at the site conducts inspection work for restoration, after confirming the position where the car 3 is stopped, the landing door 10 on the appropriate floor is opened and the inspection device 20 is connected to the hoistway. It is possible to check the state of the elevator equipment in the hoistway 2 by entering the vehicle 2 and starting the flight of the inspection device 20.

  More specifically, the inspection device 20 includes an elevator device (for example, a car guide rail 7 and a main rope as shown in FIG. 3) installed in the hoistway 2 in the air in the hoistway 2 where the car 3 moves up and down. 13) Flying means 22 having a function of flying up and down without contact with respect to an object including obstacles, and a platform 35 serving as a base of the flying means 22 and installed in the hoistway 2 And imaging means 21 having a function of imaging the elevator equipment. Here, the platform 35 of the flying means 22 has a substantially cross-shaped appearance that does not include a closed space inside. The imaging means 21 attached to the center of the substantially cross-shaped platform 35 is a hoistway. The whole inside of 2 can be imaged.

  Among these, the flying means 22 avoids an object that becomes an obstacle in the hoistway 2 and can fly in a non-contact manner from itself to the object that becomes an obstacle in the hoistway 2. Distance measuring means for measuring the distance is provided. This distance measuring means can also be used by the imaging means 21. In such a case, a laser scanner, a time-of-flight distance image sensor, a three-dimensional image is obtained in order to obtain imaging information of a three-dimensional arrangement of elevator equipment in the hoistway 2. Any one of the cameras can be applied. Further, since the platform 35 serving as the base of the above-described flying means 22 does not include a space closed inside, the distance measuring means moves the apparatus along the guide rail 7 for the car, the guide rail 9 for the weight, and the tail cord shown schematically. In addition to being able to move up and down, when these rails come off, or when a situation occurs in which the main rope 13, the governor rope 15, and the tail cord are caught by the elevator equipment in the hoistway 2, It is possible to continue the ascending / descending flight by leaving the obstacle. Incidentally, as an object to be an obstacle, for example, a wall including the landing door 10, a floor of the machine room 6 that becomes the ceiling of the hoistway 2, a pit 5 that becomes the floor of the hoistway 2, a car 3, and a counterweight 8. , Main rope 13, governor rope 15, cage guide rail 7, weight guide rail 9 and the like.

  Further, the flying unit 22 includes a recording unit 27 that records imaging information captured by the imaging unit 21, a communication unit 28 having a transmission function that transmits imaging information recorded in the recording unit 27 to the outside, and a recording unit 27. In addition to performing control of recording or reading operation of imaging information and transmission operation of imaging information to the outside via the communication unit 28, control of receiving a driving command to the flight driving unit, and flight driving based on the driving command And a control unit 32 that performs drive control to the unit. The recording unit 27 records imaging information so that the inspection result can be reviewed in detail after the inspection is completed. The communication unit 28 provides imaging information to the inspection manager in real time so that the situation image in the hoistway 2 can be confirmed. The control unit 32 allows the inspection manager to appropriately perform the inspection and easily check the inspection result without dispatching a specialized engineer separately.

  In addition, the flying means 22 includes rotating blades 30a and 30b attached to the rotation shafts of motors 29a, 29b, 29c and 29d as flight driving units provided at the ends in the four directions of the substantially cross-shaped platform 35, respectively. , 30c, 30d, and an annular contact protection portion is provided on the outermost periphery of each rotary blade 30a, 30b, 30c, 30d. This annular contact protector prevents the rotating blades 30a, 30b, 30c, 30d from stopping immediately even when the wall of the hoistway 2 or the elevator equipment touches the rotating blades 30a, 30b, 30c, 30d. The purpose is to prevent the posture of the inspection device 20 (platform 35) from collapsing.

The detailed configuration will be described in detail with reference to FIG. 2. The flying means 22 includes motors 29 a, 29 b, 29 c, and 29 d arranged at the ends in the four directions of a substantially cross-shaped platform 35, and their rotation shafts. Are equipped with rotating blades 30a, 30b, 30c, and 30d, and the motors 35a, 29b, 29c, and 29d are rotated to generate a downward airflow generated by the rotating blades 30a, 30b, 30c, and 30d. You can fly in the air and fly. That is, in the flight section 22, a motor 29a, 29 b, 29c, it is possible to raise the platform 35 vertically Increasing the rotational speed of the 29d, it is possible to lower the plat- home 35 by lowering. The annular contact protector provided on the outermost periphery of each rotary blade 30a, 30b, 30c, 30d is assumed to be a wall of the hoistway 2 or an elevator in the hoistway 2 while the rotary vanes 30a, 30b, 30c, 30d are rotating. This is for the purpose of preventing the contact point from stopping immediately when the device is in contact with the device, and the posture of the platform 35 from collapsing, and for protecting the contact of the rotating blades 30a, 30b, 30c, 30d in the rotating state. work.

  Here, in order to reduce the weight of the platform 35 as much as possible, it is desirable to use polystyrene foam, lightweight resin, wood, or the like as a material. Further, when a downward air flow is generated to lift the platform 35 in the air, not only the rotation of the rotary blades 30a, 30b, 30c, 30 but also a gas such as compressed air or gas is jetted downward. May be. Further, the electric power for driving the motors 29a, 29b, 29c, 29d is supplied from the control unit 32 installed at the upper part of the central part of the platform 35 by the battery 34 installed at the lower part of the central part of the platform 35 in order to lower the center of gravity. Is supplied to the motors 29a, 29b, 29c, and 29d. However, if the battery 34 is small and light, it may be installed at a location other than the lower portion of the central portion of the platform 35.

  By the way, the flying means 22 has a function for keeping the flight posture horizontal, and an inclination detection for detecting the flight posture (tilt angle) is provided in the middle part of the arm portion in the four directions of the platform 35. Portions 31a, 31b, 31c and 31d are provided. The control unit 32 refers to the tilt information from the tilt detection units 31a, 31b, 31c, and 31d, and controls the driving power supplied from the battery 34 to the motors 29a, 29b, 29c, and 29d, thereby rotating the rotary blade 30a, The rotation of 30b, 30c, 30d is controlled, thereby keeping the platform 35 horizontal. For the inclination detectors 31a, 31b, 31c, 31d, for example, the inclination speed is calculated based on the result of detecting gravity using a multi-axis acceleration sensor, or the inclination speed is detected using a multi-axis gyro sensor. The case of making can be illustrated.

  The flying means 22 has a function of moving in the horizontal direction, and motors 29 a, 29 b, 29 c, 29 d provided at the ends in the four directions of the substantially cross-shaped platform 35 are connected to the platform 35. The angles of the rotation axes are provided so as to be variable, and the angle of the rotation axes is controlled by the control unit 32. Here, for example, if the control unit 32 changes to the same direction and the same angle of the motors 29a, 29b, 29c, 29d, the direction of the downward airflow due to the rotation of the rotary blades 30a, 30b, 30c, 30d can be changed. As a result, the platform 35 moves horizontally to the side where the rotating shaft is tilted while keeping the floating state, and when the movement is stopped, the angles of the rotating shafts of the motors 29a, 29b, 29c, 29d may be set to the vertical direction. The movement of the flying means 22 in the horizontal direction is not limited to the structure described here. For example, the flying means 22 is generated by another motor (illustrated) provided rotatably on the platform 35 and a rotary blade attached to the rotation shaft. Alternatively, the air flow may be performed by an air flow in the horizontal direction or the lateral direction, or may be performed by jetting a gas such as compressed air or gas in the horizontal direction or the lateral direction.

  Further, the flying means 22 has a function of flying up and down in a non-contact manner with respect to an object that is an obstacle including an elevator device installed in the hoistway 2. As a distance measuring means that measures the distance from itself to an object that becomes an obstacle present in the hoistway 2 by using, for example, ultrasonic waves, light, macro waves, etc. Detection units 33a, 33b, 33c, 33d, 33e, and 33f are provided, and the control unit 32 moves the platform 35 in the horizontal direction based on distance information from the proximity detection units 33a, 33b, 33c, and 33d. Based on the distance information from the proximity detectors 33e and 33f, the platform 35 is moved up and down.

  In addition, the light emitting part 24a and the light receiving part 24h, the light emitting part 24c and the light receiving part 24b, the light emitting part 24e and the light receiving part 24d, the light emitting part 24g and the light receiving part are located at opposite positions at the end portions in the four directions of the substantially cross-shaped platform 35. 24f is provided, the light from the light emitting part 24a is incident on the light receiving part 24b and received, the light from the light emitting part 24c is incident on the light receiving part 24d and received, and the light from the light emitting part 24e is incident on the light receiving part 24f. The light from the light emitting unit 24g enters the light receiving unit 24h and is received. For example, referring to FIG. 3, when the light beam 40a from the light emitting unit 24a is blocked by the main rope 13 or the light beam 40c from the light emitting unit 24d is blocked by the car guide rail 7, the light emitting unit 24c that is not shielded from light. Compared with the light receiving unit 24d that receives the light beam 40b from the light receiving unit 24h and the light receiving unit 24h that receives the light beam 40d from the light emitting unit 24g, the amount of light received by the light receiving units 24b and 24f is greatly attenuated. It can be determined that the rope 13 and the guide rail 7 for the car are approached. Therefore, the control unit 32 performs movement control to avoid the flight state, or performs control to raise and lower the platform 35 in a state along the main rope 13 and the car guide rail 7 while maintaining the state. It becomes possible.

  On the other hand, the imaging means 21 attached to the upper part of the central part of the platform 35 with the control unit 32 and the recording unit 27 interposed therebetween is a video camera or a digital camera that captures an obstacle object including the elevator device in the hoistway 2. The imaging unit 23 using a camera or the like, the illumination unit 25 using a lamp or a light emitting diode (LED) that illuminates the imaging field of view of the imaging unit 23 in the hoistway 2, and the imaging unit 23 and the illumination unit 25 are rotated with respect to the platform 35. And a pan head 26 that is movably installed. Imaging information captured by the imaging unit 23 (image data if the image processing function is provided) is recorded by the recording unit 27 under the control of the control unit 32, and then read from the recording unit 27 and stored on the platform 35. An image is displayed on a display screen of a portable terminal having an image receiving function carried by an inspection manager via a communication unit 28 by a wireless communication device equipped with an antenna mounted on a battery 34 at a lower center portion. The

  As a result, the inspection manager can check the state of the car guide rail 7 and the weight guide rail 9 erected on the wall surface of the hoistway 2, the state of the car 3 and the counterweight 8, the main rope 13 and the governor. In addition to the rope 15, the state of the tail cord shown schematically is confirmed, for example, the guide rail 7 for the car is detached or bent, the rail 3 is removed from the car 3 or the counterweight 8, and the main rope 13 or the tail cord in the hoistway 2. It can be confirmed from the image whether or not a situation that hinders the traveling of the car 3 of the elevator 1 has occurred, such as being caught on the elevator equipment. In particular, since it is possible to confirm while raising and lowering the inspection device 20 by the flying means 22, even the long hoistway 1 can be simply and accurately determined. At this time, when the flying means 22 detects an object that becomes an obstacle in the hoistway 2, it has a function of automatically avoiding and flying in a non-contact manner, so that the main rope 13 and the tail cord are caught. Even in such a situation, the inspection can be automatically avoided and the inspection can be continued.

  When the inspection work for restoration in the hoistway 2 by the inspection device 20 is completed, the inspection manager collects the inspection device 20 by hand with the inspection device levitated at a predetermined position, or on the car 3 or the pit 5. Landing at a predetermined position, collecting it, and storing it in a predetermined place to prepare for the next inspection work. Thereafter, it is also possible to confirm the imaging information recorded in the recording unit 27 again and to perform detailed inspection confirmation.

  In the elevator inspection device 20 according to the first embodiment, the elevator 3 is attached to the flying means 22 that flies up or down in a contactless manner with an object including an elevator device in the hoistway 2 where the car 3 moves up and down. The image capturing means 21 has a function to image the elevator equipment installed in the hoistway 2 so that even if the elevator stops and cannot be moved due to the occurrence of a strong shaking earthquake, the inspection manager with expertise in the field is restored When the inspection work for the vehicle is performed, the apparatus is inserted into the hoistway 2 and moved up and down by the flying means 22 while referring to the imaging information taken by the imaging means 21, the elevator equipment installed in the hoistway 2 The situation can be grasped accurately. As a result, regardless of the length of the hoistway 2, the elevator equipment in the hoistway 2 can be simply inspected quickly and accurately, and the elevator can be restored early.

  FIG. 4 is an external view showing the basic configuration of the elevator inspection apparatus 20a according to the second embodiment of the present invention from the upper surface direction. Compared with the inspection device 20 of the first embodiment, the inspection device 20a has a substantially Y-shaped appearance that does not include a space in which the platform 35a of the flying means 22 is closed, and the end of the platform 35a in three directions. The difference is that the flying means 22 similar to that of the first embodiment is provided in the part, and the imaging means 21 is provided in the central part. The imaging unit 23 in the imaging unit 21 here is not an optical imaging unit such as the video camera or the digital camera exemplified in the first embodiment. For example, the hoistway 2 emits laser light in a fan shape in the horizontal direction. Distance measuring means such as a laser scanner that calculates the distance by measuring the round trip time of the reflected light reflected by the wall surface of the elevator and the elevator equipment, or the pulsed light is emitted and reflected by the wall surface of the hoistway 2 and the elevator equipment. It is possible to use a time-of-flight distance image sensor that measures the round trip time of the reflected light and calculates a distance, or a three-dimensional camera that performs stereoscopic viewing with two cameras. Since these devices function as distance measuring means for measuring the distance to an object that becomes an obstacle in the hoistway 2, their functions can be provided without providing proximity detection units at three end portions of the platform 35 a. Can be substituted. In any case, in the inspection device 20a according to the second embodiment, the control unit 32 can control the horizontal position of the platform 35a based on the distance information from the distance measuring unit, and can display the distance information in a three-dimensional manner. Therefore, as in the case of the first embodiment, the situation of the elevator equipment installed in the hoistway 2 can be accurately grasped, and as a result, the hoistway 2 can be raised and lowered quickly and accurately regardless of the length of the hoistway 2. The elevator equipment in the road 2 can be easily inspected and the elevator 1 can be restored early.

  FIG. 5 is an external view showing the basic configuration of the elevator inspection apparatus 20b according to the second embodiment of the present invention from the upper surface direction. Compared to the inspection device 20 of the first embodiment, the inspection device 20b has a substantially U-shaped external shape that does not include a space in which the platform 35b of the flying means 22 is closed, and the end and corners of the platform 35b. The flight means 22 similar to that of the first embodiment is provided at the corner, and the imaging means 21 is provided at the center of the column portion. Further, the inspection device 20b here is installed in advance by the inspection manager on the ceiling of the hoistway 2 which is the floor of the machine room 6, the pit 5 which becomes the floor of the hoistway 2, and the upper or lower portion of the outer wall of the car 3. A setting is made so that the elevator apparatus in the hoistway 2 is automatically inspected when a strong earthquake occurs and the elevator 1 stops. In this way, since the inspection manager can complete the inspection work when arriving at the site where the elevator 1 is installed, the hoistway 2 can be referred to by referring to the imaging information recorded in the recording unit 27. By confirming the state of the elevator equipment, the elevator 1 can be restored more quickly.

  FIG. 6 is an external view showing the basic configuration of the elevator inspection apparatus 20c according to the third embodiment of the present invention from the upper surface direction. Compared with the inspection device 20 of the first embodiment, the inspection device 20c has a substantially C-shaped external shape that does not include a space in which the platform 35c of the flying means 22 is closed. The difference is that the flying means 22 similar to that of the first embodiment is provided at a location where the parts face each other, and the imaging means 21 is provided at an intermediate location. Further, the inspection device 20c here transmits the imaging information recorded in the recording unit 27 at a remote monitoring base schematically illustrated via a communication line schematically illustrated via the communication unit 28 under the control of the control unit 32. The control of the control unit 32 is controlled via the communication line via the communication line to send a command for confirming the inspection or to remotely control the flight state of the inspection device 20c from a remote monitoring base. This is what we do. If it is such a setting, unlike the case of Example 1-Example 3, it is not necessary for an inspection manager to go to the installation place of the elevator 1, and inspection check can be performed at a monitoring base, and according to an inspection result. Furthermore, the elevator 1 can be restored quickly.
