  Hereinafter, embodiments of the present invention will be described using the drawings.

  1 to 4 are diagrams showing the configuration of the photographing instrument in the present embodiment. 1 and 3 show the photographing instrument with the background plate closed, and FIGS. 2 and 4 show the photographing instrument with the background plate open.

  The photographing instrument in the present embodiment is a photographing instrument for photographing the suspension line 100 at a high place by attaching the camera 30 to the tip of the long operation rod 20. The tip of the photographing apparatus includes a camera installation stand 11, a hanging line holding unit 12, a background plate 13, a hinge 14 for attaching the background plate 13 so that it can be opened and closed, a background plate lock 15, a hanging line detection unit 16, and a background plate lock 15. A lock holding unit 17 that holds the suspension wire detection unit 16 so as to be movable up and down, a frame 18 to which the above-described units are attached, and an attachment unit 19 for attaching the frame 18 to the operation rod 20 are provided.

  The camera mount 11 is a mount, which is disposed at the top of the frame 18, for setting the camera 30 downward (in the direction of the operation rod 20).

  The hanging wire holding portion 12 is a pair of arm arms extended from the frame 18 and disposed below the camera mount 11 (on the side of the operation rod 20). When photographing the drag line 100, as shown in FIGS. 2 and 4, the drag line 100 is held inside the apex of each of the arms. In a state in which the holding unit 12 holds the hanging line 100, the camera 30 captures an image of the holding unit 100 between the holding units 12. The suspension line holding unit 12 may have any shape as long as the suspension line 100 can be fixed so as not to move during photographing. The distance between the camera installation base 11 and the suspension line holding unit 12 may be changed in accordance with the focus of the camera 30 to be installed. For example, the position of the camera installation stand 11 can be changed.

  The background plate 13 is a plate that is disposed below the suspension line holding unit 12 and serves as a background of the suspension line 100 during photographing. The background plate 13 is disposed so as to be perpendicular to the viewing direction of the camera 30 (longitudinal direction of the operation rod 20). The background plate 13 is attached to the frame 18 by a hinge 14 at one side, and is rotatable about the one side to which the hinge 14 is attached. Here, a state in which the background plate 13 is perpendicular to the frame 18 (the operation rod 20) is referred to as a state in which the background plate is open, and a state in which the background plate 13 is parallel to the frame 18 (not necessarily completely parallel). It is said that the background plate is closed. The background plate 13 functions in the open state as the background of the suspension line 100 during shooting.

  The background plate lock 15 is a locking portion that is movable up and down and can be fixed in a state in which the background plate 13 is closed. When the background plate lock 15 is raised in a state where the background plate 13 shown in FIGS. 1 and 3 is closed, the background plate 13 is opened by its own weight as shown in FIGS.

  The suspension line detection unit 16 is an arm that is connected to the background plate lock 15 and extends from the frame 18. The hanging line detection unit 16 and the background plate lock 15 move integrally. When the suspension line 100 is held by the suspension line holding unit 12, the suspension line detection unit 16 is pushed up by the suspension line 100. When the suspension line detector 16 is pushed up, the background plate lock 15 also moves upward, so that the background plate lock 15 is released and the background plate 13 is opened.

  The frame 18 is a frame to which the above-described components are attached. The frame 18 has an opening at the center, and it can be confirmed from either side of the frame 18 that the drop line 100 approaches the drop line holding portion 12.

  The attachment portion 19 is a member for attaching the frame 18 to the tip of the operation rod 20. It is good to have a mechanism that can be attached and detached with one touch. The mounting portion 19 has an inclined surface on the side of the wire holding portion 12. The slope of the attachment portion 19 functions as a guide when the suspension wire 100 is hooked on the suspension wire holding portion 12.

  The operating rod 20 is a long rod for attaching the above-mentioned tip. The operating rod 20 only needs to have a length sufficient for the tip to reach the anchor 100 and a sufficient strength to support the tip. The operating rod 20 may be of a swing-out type or a plug-in type.

  Next, a photographing method using the photographing instrument of the present embodiment will be described.

  First, the camera 30 is installed on the camera installation table 11, the background plate 13 is locked in a closed state, and the tip is fixed to the operation rod 20. Extend the operating rod 20 with the tip attached to the required length (up to 6.5 m).

  Then, the operating rod 20 (slightly below the attachment portion 19) is applied to the suspension line 100, and the operation rod 20 is lowered until the suspension wire 100 stops at the suspension wire holding portion 12. When lowering the operating rod 20, the operating rod 20 is put on the suspension line 100 so that the operating rod 20 is brought into contact with the suspension line 100 and the operating rod 20 is lowered. When the suspension line 100 gets over the attachment part 19, the slope of the attachment part 19 serves as a guide for the suspension line 100, so that the suspension line 100 is not caught by the attachment part 19.

  When the operating rod 20 is continuously lowered, the suspension line 100 gets over the closed background plate 13 (the back surface of the background plate 13) and pushes up the suspension line detection unit 16. When the suspension line detection unit 16 is pushed up to the suspension line holding unit 12, the background plate lock 15 is released and the background plate 13 is opened. After that, the hanging wire 100 stops at the hanging wire holding portion 12.

  The operator starts photographing with the camera 30 while the suspension line holding unit 12 holds the suspension line 100. The camera 30 is operated wirelessly. The image captured by the camera 30 may be transmitted to the terminal of the worker.

  After the shooting of the hanging line 100, the operating rod 20 is folded.

  As described above, when shooting the drag line 100, the operating rod 20 is placed on the lifting wire 100 so that the lifting rod holding portion 12 is hooked on the lifting wire 100. Because it is good, it can handle the photographing instrument very stably.

  Next, modified examples of the photographing instrument of the present embodiment will be described.

  FIG. 5 is a schematic side view showing the configuration of Modification 1 of the photographing instrument of the present embodiment. The imaging device of the first modification locks the background plate 13 by magnetic force, using the background plate lock 15 of the imaging device of FIGS. 1 to 4 as a magnet. In order to attach the background plate 13 to the background plate lock 15, a magnet or metal is disposed at a position corresponding to the background plate lock 15 of the background plate 13, or the entire background plate 13 is made of metal. Also in the photographing instrument of Modification 1, when the suspension line detection unit 16 is pushed up, the background plate lock 15 is raised, the contact between the background plate lock 15 and the background plate 13 is released, and the background plate 13 is opened.

  Further, as shown in FIG. 5, when the string 21 is attached to the background plate 13 of the photographing instrument of the first modification, the operator can pull the string 21 to manually open the background plate 13. The length of the string 21 is about the maximum length (6.5 m) of the photographing instrument. The string 21 can be attached to the background plate 13 by, for example, an L-shaped fitting. When the background plate 13 is closed, the L-shaped bracket is drawn to the background plate lock 15.

  FIG. 6 is a schematic side view showing the configuration of Modification 2 of the photographing instrument of the present embodiment. The photographing instrument of the modified example 2 is the photographing instrument of FIGS. 1 to 4 from which the background plate lock 15, the hanging wire detection unit 16, and the lock holding unit 17 are removed. The background plate 13 is attached so as to be openable and closable similarly to the photographing instrument of FIGS.

  The operation rod 20 of the photographing instrument of the modified example 2 is put on the suspension line 100 and the operation rod 20 is lowered until the suspension line 100 stops at the suspension line holding unit 12. In the attachment portion 19, the slope serves as a guide for the suspension line 100, and the suspension line 100 easily gets over the attachment portion 19. Thereafter, the suspension line 100 comes into contact with the lower surface of the background board 13, but when the operating rod 20 is further lowered, the background board 13 is closed by being pushed by the suspension line 100. The hanging line 100 passes over the back surface of the closed background plate 13. When the suspension line 100 finishes passing through the background plate 13, the background plate 13 is opened again by its own weight. When the suspension line 100 stops at the suspension line holding unit 12, the suspension line 100 is photographed.

  As described above, the photographing instrument of the modified example 2 does not include the background plate lock 15 that locks the background plate 13 in the closed state. However, like the photographing instrument of FIGS. Since the background plate 13 is opened and closed simply by lowering the operating rod 20 by hitting, the suspension line 100 can be held by the suspension line holding unit 12 without the background plate 13 getting in the way.

  FIG. 7 is a schematic side view showing the configuration of Modification 3 of the photographing instrument of the present embodiment. The photographing instrument of Modification 3 is obtained by attaching a string 21 to the background plate 13 of the photographing instrument of Modification 2. A through hole was provided in the frame 18 at the attachment position of the string 21 when the background plate 13 was closed, and the string 21 was passed through the through hole. When the operator pulls the string 21, the background plate 13 is closed, and when the operator loosens the string 21, the background plate 13 opens.

  As another modification, the camera installation stand 11, the hanging wire holding portion 12, and the background plate 13 may be directly attached to the operating rod 20 without using the frame 18. For example, the suspension support 12 arranges a horizontal bar perpendicular to the operating bar 20 and attaches a pair of arms at a distance to the horizontal bar.

  As described above, according to the present embodiment, the camera installation base 11 for mounting the camera 30 with the downward direction as the imaging direction, and the suspension provided below the camera installation base 11 and holding the hanging wire 100 at the time of imaging The provision of the line holding unit 12 and the background plate 13 serving as the background of the hanging line 100 at the time of photographing eliminates the need for a flexible arm for installing a camera so as to photograph the hanging line from the side direction. A wide space in front of the camera can be secured, and handling of the photographing instrument during photographing becomes easy. Moreover, since the lens of the camera 30 faces downward, the anxiety of surrounding residents can be solved.

  According to the present embodiment, by rotatably attaching the background plate 13, the operating rod 20 is brought into contact with the drop wire 100 so that the drop rod holding portion 12 is hooked onto the drop wire 100. Since it is only necessary to lower the position, it is possible to handle the photographing instrument very stably.

  According to the present embodiment, the background plate 13 can be moved up and down in conjunction with the load line detection section 16 moving upward when the load line 100 approaches the load line holding section 12 and the load line detection section 16. The background plate 13 can be easily opened by providing the background plate lock 15 that locks in a closed state and releases the lock when the hanging wire detection unit 16 moves upward.

  According to the present embodiment, the camera installation base 11, the suspension line holding unit 12, and the frame 18 to which the background plate 13 is attached are provided, and the suspension line 100 becomes the suspension line holding unit by opening the center of the frame 18. It can be confirmed from either side of the frame 18 that it approaches the position 12. In addition, by making the frame 18 detachable from the operation rod 20, it is easy to carry the photographing instrument.
