Description

[Technical Field]

[0001] The present disclosure relates to an assisted high-altitude inspection device equipped with measuring equipment. [Background technology]

[0002] For example, a bridge 100, such as that shown in FIG. 1, is inspected periodically or irregularly for its maintenance. During inspection of the bridge 100, the exterior of almost the entire bridge 100 may be inspected. However, some areas are difficult to inspect, such as the lower part 102a (inspected area indicated by the bold line) of the main girder 102 supporting the deck 101 of the bridge 100, and the outer surface (inspected area) 103a of drainage pipes and cables. For such difficult-to-inspect areas, a pole camera with a high-resolution camera attached to the tip of a pole may be used as an alternative to close-up visual inspection. When using a pole camera, a worker on the ground holds the bottom of the pole and adjusts the camera's position by manipulating the pole from the ground so that the area to be inspected is within the camera's field of view. Images are then captured by the camera, and the bridge 100 can be inspected based on the captured images.

[0003] Furthermore, for example, Patent Document 1 discloses a measuring instrument movement assistance device in which a lift generating unit is connected to the top of a support rod that is operated by an operator from the ground. A measuring instrument can be attached to the lift generating unit. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6949071 Summary of the Invention [Problem to be solved by the invention]

[0005] As in Patent Document 1, by connecting a lift generating unit to the top of the support rod, the lift generated by the lift generating unit acts as an upward force on the measuring instrument, i.e., the camera, and this upward force acts as an auxiliary force, thereby reducing the burden on the worker when working.

[0006] However, in Patent Document 1, since the measuring equipment is attached to the lift generating unit, during inspection, not only the measuring equipment but also the lift generating unit must be moved close to the inspected part. In this case, the lift generating unit has multiple rotors arranged horizontally, and therefore has a large body that extends horizontally. As a result, the lift generating unit may interfere with the inspected part, reducing the degree of freedom in positioning the measuring equipment during inspection and potentially reducing the accuracy of the inspection.

[0007] Furthermore, for example, when capturing an image of a portion of the bridge 100 with a camera, it is necessary to maintain a constant distance between the camera and the portion of the bridge 100 being inspected. In other words, the camera's field of view becomes wider as the camera moves farther away from the portion being inspected, and conversely, becomes narrower as the camera moves closer to the portion being inspected. If the camera's field of view becomes wider or narrower, the imaging range of the captured image will differ for each image, which may make it difficult to make a judgment based on a predetermined standard. For example, if a crack on the surface of the bridge 100 is captured in an image, if the imaging range of the image is not constant, it may be impossible to objectively obtain the width and length of the crack, which may ultimately reduce the accuracy of the inspection. This is also true for measuring devices other than cameras.

[0008] The present disclosure has been made in consideration of such points, and its purpose is to improve the accuracy of inspection by assisting inspection of high altitudes using measuring equipment with a lift generating unit, while maintaining a constant positional relationship between the inspected part and the measuring equipment. [Means for solving the problem]

[0009] In order to achieve the above object, one aspect of the present disclosure can be premised on an assisted high-altitude inspection device equipped with a measuring device such as a camera. The assisted type refers to a device that can assist an operator during inspection.

[0010] The assisted high-altitude inspection device includes a pole that extends in the vertical direction and on which the measuring equipment is attached, a lift generating unit that has rotating wings and is attached to the middle part of the pole in the vertical direction, and a distance setting member that is fixed to the top of the pole, protrudes in a direction intersecting the axis of the pole, contacts the part to be inspected, and sets the distance between the measuring equipment and the part to be inspected to a predetermined distance.

[0011] With this configuration, when using a measuring instrument to inspect a high-altitude inspection target such as a bridge, the lifting force of the lift generating unit acts as an auxiliary force when positioning the measuring instrument at the desired high-altitude position, reducing the burden on the worker. During inspection using the measuring instrument, the lift generating unit is located below and away from the measuring instrument, so when the measuring instrument is brought close to the inspection target, the lift generating unit is less likely to interfere with the inspection target. This increases the degree of freedom in positioning the measuring instrument.

[0012] Furthermore, by having the distance setting member come into contact with the part to be inspected, it is possible to maintain a predetermined distance between the measuring instrument and the part to be inspected during inspection. This allows inspections to be performed under the same conditions at all times, improving inspection accuracy.

[0013] The pole may have a structure that does not have any bending portions. For example, the pole may be arranged so as to vertically penetrate a central portion of the lift generating unit, which is surrounded by three or more rotors. In this case, the vertical middle portion of the pole and the central portion of the lift generating unit may be connected via an angle adjustment mechanism that is rotatable around a horizontal axis. With this configuration, the angle of the lift generating unit relative to the pole can be adjusted by rotating the lift generating unit around the horizontal axis. This improves the degree of freedom during inspection.

[0014] The assisted-type high-altitude inspection device may have a mounting part to which the measuring instrument is attached, a support part that supports the mounting part rotatably about an axis extending in a direction intersecting the pole relative to the upper part of the pole, and a drive part that rotates the mounting part about the axis relative to the support part. This forms a movable gimbal mechanism, so that by rotating the mounting part with the drive part, the angle of the measuring instrument can be easily changed to match the part to be inspected.

[0015] The distance setting member may have a base portion fixed to an upper portion of the pole and extending radially to both sides of the pole, a first protrusion portion protruding from one end of the base in a direction intersecting the axis of the pole, and a second protrusion portion protruding from the other end of the base in a direction intersecting the axis of the pole. The first protrusion portion and the second protrusion portion may protrude in the same direction. This allows the first protrusion portion and the second protrusion portion, which are separated from each other, to come into contact with the part to be inspected during inspection, thereby enabling stable positioning of the measuring instrument.

[0016] A first roller supported by a vertically extending spindle may be provided at the tip of the first protrusion. A second roller supported by a vertically extending spindle may be provided at the tip of the second protrusion. This allows the measuring instrument to be easily moved horizontally while keeping the first roller and second roller in contact with the inspected part.

[0017] The lift generating portion may have a protective member formed to surround the rotor. In this case, the first protrusion and the second protrusion may protrude outward from the protective member in a plan view. This allows the first protrusion and the second protrusion to come into contact with the inspection target before the protective member hits the inspection target, thereby preventing damage or deformation of the protective member. [Effects of the Invention]

[0018] As described above, inspection of high places using a measuring instrument can be assisted by the lift generating unit, while maintaining a constant positional relationship between the inspected part and the measuring instrument, thereby improving the accuracy of the inspection.

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0021] 2 to 5 show an assisted-type high-altitude inspection device 1 equipped with a measuring device according to an embodiment of the present invention. In this embodiment, the assisted-type high-altitude inspection device 1 equipped with a measuring device includes a camera 2 as a measuring device. The camera 2 is a high-resolution digital camera capable of capturing still images and video. Image data acquired by the camera 2 during inspection is stored in a storage medium (not shown). During inspection, the camera 2 may capture still images or video. During inspection, the camera 2 may continuously capture video, and after inspection, the presence or absence of an abnormality may be determined based on the acquired video. The image data captured by the camera 2 may also be transmitted to a worker on the ground so that the condition of the high altitude can be confirmed on the ground. The worker on the ground may also remotely operate the camera 2 and release the shutter of the camera 2 at a desired timing. The live view image acquired by the camera 2 may also be transferred to a controller C on the ground and displayed on a display screen (not shown) of the controller C.

[0022] The measuring device is not limited to the camera 2, but may be various other measuring devices such as a dimension measuring device, a surface roughness measuring device, a color measuring device, etc. When the measuring device is a camera 2, it can also be called an assisted high-altitude inspection device 1 equipped with a camera 2. In the following description, the assisted high-altitude inspection device 1 equipped with a measuring device will simply be called the assisted high-altitude inspection device 1.

[0023] The assisted high-altitude inspection device 1 is a device for assisting inspection work using a camera 2. The assisted high-altitude inspection device 1 is used, for example, when inspecting a bridge 100 as shown in FIG. 1. Objects that can be inspected with the assisted high-altitude inspection device 1 are not limited to the bridge 100, but can also include, for example, houses, buildings, factories, steel towers, electric wires, and pipes. By using the assisted high-altitude inspection device 1, these high places can be inspected without the worker having to climb up. A high place is, for example, 2 meters or more, or 3 meters or more, and is a place located at a height that cannot be visually inspected by a worker on the ground.

[0024] The assisted high-altitude inspection device 1 has a pole 3 that extends in the vertical direction and to which a camera 2 is attached, a lift generating unit 4 that is attached to the vertical middle of the pole 3, and a distance setting member 5 that is fixed to the top of the pole 3. The lift generating unit 4 and the distance setting member 5 can also be removed from the pole 3. The camera 2 can also be removed from the pole 3. This allows the assisted high-altitude inspection device 1 to be made compact when transporting.

[0025] In Figures 2 to 4, the axis of the pole 3 extends vertically. The length of the pole 3 is not particularly limited and can be, for example, approximately 10 m. The pole 3 may be composed of a single rod extending linearly, or may be composed of multiple rods connected linearly. For example, the weight of the pole 3 can be reduced by using hollow rods. When connecting multiple rods to form the pole 3, multiple hollow rods of different diameters are prepared, with the smaller diameter rods accommodated inside the larger diameter rods. When in use, the smaller diameter rods are advanced from the larger diameter rods and their ends fastened and fixed to each other to form a long pole 3. On the other hand, as shown in Figure 6, when not in use, the ends of the smaller diameter rods are released from the fastening of the ends of the larger diameter rods, and the smaller diameter rods are accommodated inside the larger diameter rods, thereby shortening the pole 3. In this way, three or more hollow rods of different diameters can also be connected. That is, by configuring the pole 3 with a plurality of rods, it is possible to make the pole 3 extendable. Furthermore, by making the pole 3 extendable, it is also possible to adjust the length of the pole 3.

[0026] The pole 3 itself is not provided with a folding or bending mechanism. Therefore, the pole 3 cannot be folded or bent at the middle part in the axial direction. Because the pole 3 has such a non-folding and non-bending structure, the structure of the pole 3 can be simplified.

[0027] The lift generating unit 4 can be configured, for example, as an unmanned aerial vehicle, a drone, or the like. As shown in FIG. 5, the lift generating unit 4 has four rotors 40, an airframe 41, and a protective member 42. The four rotors 40 are arranged to surround the central portion of the lift generating unit 4 in a plan view and are positioned at approximately the same height. A main body 41a is provided in the central portion of the airframe 41 surrounded by the four rotors 40. A line that passes through the central portion of the main body 41a in a plan view and extends in the vertical direction is defined as the center line of the main body 41a. A through-hole 41c that penetrates in the vertical direction is formed in the central portion of the main body 41a.

[0028] Four arms 41b are provided on the main body 41a. The four arms 41b extend radially from the main body 41a and are positioned at equal intervals of 90° around the circumferential direction of the center line of the main body 41a. A motor 41d for driving the rotor 40 to rotate is attached to the tip of each arm 41b. The rotor 40 is fixed to the output shaft of the motor 41d.

[0029] The main body 41a is equipped with a control unit (including a microcomputer, etc.) for controlling the motor 41d, and a circuit board (not shown) on which various sensors (including an acceleration sensor, an atmospheric pressure sensor, a GPS sensor, etc.) are mounted. As shown in FIG. 2, the motor 41d is supplied with power from an external battery B. The external battery B can be carried by, for example, a ground worker. A power supply line B1 extending from the external battery B is connected to the control board of the main body 41a. Note that instead of or in addition to the external battery B, a battery (not shown) may be mounted on the aircraft 41.

[0030] The main body 41a is also equipped with a communication module (not shown) capable of communicating with a controller C operated by a ground worker. The operating state of the controller C is converted into a predetermined control signal and transmitted to the communication module of the main body 41a. Based on the control signal received by the communication module, the control unit controls each motor 41d, allowing the four rotors 40 to generate lift, enabling, for example, hovering or flight at a predetermined speed. Control of the magnitude of the lift generated by the four rotors 40 and control of the direction of travel of the lift generating unit 4 can be performed based on conventionally known control methods.

[0031] In plan view, the protective member 42 has a frame shape that surrounds the four rotor blades 40. Inside the protective member 42, a connecting member 42a is provided that is connected to the tip end of each arm 41b.

[0032] As shown in Figures 7 to 10, the assisted high-altitude inspection device 1 further includes an angle adjustment mechanism 6 that connects the pole 3 and the lift generating unit 4 so that the angle can be adjusted. That is, the vertical middle portion of the pole 3 is arranged so as to vertically pass through a through-hole 41c (shown by virtual lines in Figures 8 and 9) in the body 41 of the lift generating unit 4. The through-hole 41c is located in the central portion of the lift generating unit 4 that is surrounded by three or more rotors 40.

[0033] The angle adjustment mechanism 6 includes a body-side frame member 60, a pole-side frame member 61, a fixing member 62 fixed to the top surface of the body 41, a first shaft 63, and a second shaft 64. A pair of fixing members 62 are provided to sandwich the opening of the through-hole 41c on the top surface of the body 60 in the width direction. The body-side frame member 60 is sized to allow the pole 3 to be inserted therein and is disposed between the pair of fixing members 62. Two first shafts 63 are provided corresponding to the pair of fixing members 62, and each is disposed to extend in a direction intersecting the axis A of the pole 3 (shown in FIG. 8, etc.). In this embodiment, as shown in FIGS. 8 and 9, when the top surface of the body 60 is horizontal and the axis A of the pole 3 is vertical, the orientation of the first shafts 63 is set so that the extension direction of the first shafts 63 and the axis A of the pole 3 are perpendicular to each other.

[0034] One end of each first shaft 63 is supported by the fixed member 62, and the other end is supported by the aircraft body frame member 60. One end of the first shaft 63 may be rotatable relative to the fixed member 62, or the other end of the first shaft 63 may be rotatable relative to the aircraft body frame member 60.

[0035] The pole-side frame member 61 is smaller than the aircraft-side frame member 60 and is arranged inside the aircraft-side frame member 60. The pole 3 can be inserted inside the pole-side frame member 61. The inner part of the pole-side frame member 61 is attached to the outer peripheral surface of the pole 3. The pole-side frame member 61 can be rotated around the axis A of the pole 3, and is fixed to the pole 3 when it has reached the desired rotation angle.

[0036] Two second axes 64 are also provided. In plan view, the second axes 64 extend in a direction perpendicular to the direction in which the first axes 63 extend. The first axes 63 and the second axes 64 are alternately arranged at 90° intervals around the circumferential direction of the pole 3. Therefore, the two first axes 63 are positioned on a first straight line L1 (shown in FIG. 10), and the two second axes 64 are positioned on a second straight line L2 that is perpendicular to the first straight line L1.

[0037] One end of each second shaft 64 is supported by the aircraft body frame member 60, and the other end is supported by the pole side frame member 61. One end of the second shaft 64 may be rotatable relative to the aircraft body frame member 60, or the other end of the second shaft 64 may be rotatable relative to the pole side frame member 61.

[0038] By providing the angle adjustment mechanism 6 configured as described above, the lift generating unit 4 can be rotated about the first axis 63 relative to the pole 3 to adjust the angle about the first axis 63, and the lift generating unit 4 can be rotated about the second axis 64 relative to the pole 3 to adjust the angle about the second axis 64. When adjusting the angle of the lift generating unit 4 relative to the pole 3, the angle may be adjusted only about the first axis 63, or only about the second axis 64. The angle adjustment mechanism 6 may be provided as needed, or may be omitted.

[0039] 11 and 12, the assisted high-altitude inspection device 1 further includes a gimbal mechanism 7. The gimbal mechanism 7 is a mechanism that supports the camera 2 on the pole 3 and enables the angle of the camera 2 to be adjusted.

[0040] The gimbal mechanism 7 has a mounting portion 70 to which the camera 2 serving as a measuring device is attached, a support portion 71 that supports the mounting portion 70, and a drive portion 72. The support portion 71 has a base portion 71a that extends in a direction perpendicular to the axis A of the pole 3, and extension portions 71b that extend upward from both ends of the base portion 71a. The base portion 71a is fixed to the mounting plate 3a of the pole 3 using a fixture (not shown) so as not to move.

[0041] The mounting part 70 has a first rod-shaped part 70a extending parallel to the base part 71a of the support part 71, and second rod-shaped parts 70b extending upward from both ends of the first rod-shaped part 70a. The camera 2 is fixed to the first rod-shaped part 70a. If necessary, a light 8 can also be attached to the mounting part 70. The light 8 is a member for irradiating the field of view of the camera 2 with light, and is supplied with power from an external battery B.

[0042] A shaft 70c is provided at the tip of the second rod-shaped portion 70b, and is rotatably supported relative to the tip of the extending portion 71b of the support portion 71. The shaft 70c extends in a direction intersecting with the axis A of the pole 3. As a result, the mounting portion 70 is supported rotatably around the shaft 70c, which extends in a direction intersecting with the axis A of the pole 3, relative to the upper portion of the pole 3.

[0043] The drive unit 72 has a motor 72a (shown only in FIG. 12 ) for rotating the shaft 70c. When the rotational force of the motor 72a of the drive unit 72 is transmitted to the shaft 70c, the second rod-shaped portion 70b and the first rod-shaped portion 70a, which are integrated with the shaft 70c, rotate around the center line of the shaft 70c. Because the camera 2 is fixed to the first rod-shaped portion 70a, the angle of the camera 2 can be adjusted by rotating the first rod-shaped portion 70a around the center line of the shaft 70c. The drive unit 72 is operated by a ground operator operating the controller C. For example, when an angle adjustment button or the like (not shown) provided on the controller C is operated, a control signal based on the direction and amount of operation is generated and transmitted to the communication module of the main body 41a. The control unit controls the drive unit 72 based on the control signal received by the communication module, thereby adjusting the angle of the camera 2 to any angle. The angle of the camera 2 can be adjusted while viewing the image captured by the camera 2.

[0044] The distance setting member 5 is a member for setting a predetermined distance between the camera 2 and an inspection target portion at a height (indicated by an imaginary line with symbol D in FIG. 5 ), and is provided at a position spaced above the lift generating unit 4. Specifically, as shown in FIGS. 13 and 14 , the distance setting member 5 has a base 50 fixed to the top of the pole 3 and extending radially to both sides of the pole 3, a first protrusion 51 protruding from one end of the base 50 in a direction intersecting with the axis A of the pole 3, and a second protrusion 52 protruding from the other end of the base 50 in a direction intersecting with the axis A of the pole 3. When the optical axis direction of the camera 2 is horizontal, the protruding directions of the first protrusion 51 and the second protrusion 52 are parallel to the optical axis direction of the camera 2, and are the same in this embodiment.

[0045] 5, the length of the base 50 is set shorter than the width dimension of the protective member 42, and both ends of the base 50 are positioned inside the protective member 42 in a plan view. In a plan view, the first protrusion 51 and the second protrusion 52 protrude outward from the protective member 42 and have the same length. The lengths of the first protrusion 51 and the second protrusion 52 may be configured to be adjustable.

[0046] A first roller 51b supported by a first support shaft 51a extending in the vertical direction is provided at the tip of the first protrusion 51. A second roller 52b supported by a second support shaft 52a extending in the vertical direction is provided at the tip of the second protrusion 52. The first roller 51b and the second roller 52b are parts that come into contact with the inspected portion D. With the first roller 51b and the second roller 52b in contact with the inspected portion D, the imaging conditions (optical magnification, focus, etc.) of the camera 2 are adjusted so that the field of view of the camera 2 falls within a predetermined range, and the lengths of the first protrusion 51 and the second protrusion 52 are adjusted to predetermined lengths.

[0047] When the assisted high-altitude inspection device 1 is moved horizontally with the first roller 51b and the second roller 52b in contact with the inspected portion D, the first roller 51b and the second roller 52b roll on the inspected portion D. The first roller 51b and the second roller 52b may be omitted.

[0048] (High-altitude inspection method) Next, a method for performing high-altitude inspection work using the assisted high-altitude inspection device 1 configured as described above (high-altitude inspection method) will be described. First, as shown in FIGS. 2 to 4, the length of the pole 3 is adjusted to the desired length. Then, the camera 2 is attached to the mounting portion 70 of the gimbal mechanism 7. Then, the angle of the lift generating unit 4 relative to the pole 3 is adjusted using the angle adjustment mechanism 6. After the angle adjustment, the lift generating unit 4 is locked so that it does not move relative to the pole 3.

[0049] During inspection, a worker on the ground (first worker) holds the lower part of the pole 3. Another worker (second worker) operates the controller C to operate the lift generating unit 4. Lift is generated by the rotation of the rotors 40 of the lift generating unit 4, reducing the weight of the assisted high-altitude inspection device 1. The lift generating unit 4 generates lift to the extent that the assisted high-altitude inspection device 1 does not move upward more than necessary (to the extent that it does not fly). The magnitude of the lift generated by the lift generating unit 4 can be changed by operating the controller C. The lift generating unit 4 can also be made to generate a force that acts in a direction that moves the assisted high-altitude inspection device 1.

[0050] The first worker holding the lower part of the pole 3 moves the assisted high-altitude inspection device 1 to begin the inspection. As shown in FIG. 5, the assisted high-altitude inspection device 1 is moved so that the area to be inspected D is within the field of view of the camera 2, and the first roller 51b and the second roller 52b are brought into contact with the area to be inspected D. In this state, the camera 2 captures an image of the area to be inspected D. At this time, the lengths of the first protrusion 51 and the second protrusion 52 are adjusted to predetermined lengths, so that inspection can always be performed under the same conditions, improving the accuracy of the inspection.

[0051] Furthermore, the lifting force of the lift generating unit 4 acts as an auxiliary force when positioning the camera 2 at the desired high location, reducing the burden on the first worker holding the lower part of the pole 3. Furthermore, when inspecting with the camera 2, the lift generating unit 4 is located below and away from the camera 2, so when the camera 2 is brought close to the inspected part D, the lift generating unit 4 is less likely to interfere with the inspected part D. This increases the degree of freedom in the positioning of the camera 2.

[0052] The above-described embodiment is merely illustrative in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of equivalents of the claims are within the scope of the present invention. During inspection, the assisted high-altitude inspection device 1 may be moved vertically or diagonally. When moving the assisted high-altitude inspection device 1 vertically, the orientation of the first support shaft 51a and the second support shaft 52a may be changed so that the rotation direction of the first roller 51b and the second roller 52b is vertical. Specifically, the first support shaft 51a and the second support shaft 52a extend horizontally. When moving the assisted high-altitude inspection device 1 diagonally, the orientation of the first support shaft 51a and the second support shaft 52a may be changed so that the rotation direction of the first roller 51b and the second roller 52b is diagonal. In other words, the rotation direction of the first roller 51b and the second roller 52b may be around an axis extending vertically, around an axis extending horizontally, or around an inclined axis. The assisted type high-place inspection device 1 may be moved vertically or obliquely without changing the orientation of the first support shaft 51a and the second support shaft 52a.

[0053] When changing the orientation of the first support shaft 51a and the second support shaft 52a, the first protrusion 51 and the second protrusion 52 are removed from the base 50, rotated about the long axis so that the first support shaft 51a and the second support shaft 52a are oriented in the desired direction, and then attached to the base 50. Furthermore, the first roller 51b and the second roller 52b may be configured to rotate 360° about a horizontal rotation axis by, for example, a caster mechanism. [Industrial Applicability]

[0054] As described above, an assisted high-altitude inspection device equipped with a measuring instrument according to the present disclosure can be used, for example, when inspecting the exterior of a bridge or the like. [Explanation of symbols]
