[0010] The embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals, and redundant explanations are appropriately simplified or omitted. Note that the subject matter of the present disclosure is not limited to the following embodiments, and any component of the embodiments may be modified or omitted within the scope of the gist of the present disclosure.

[0011] Embodiment 1 FIG. 1 is a configuration diagram of an elevator 1 according to the first embodiment.

[0012] The elevator 1 is applied to a building having multiple floors. A hoistway 2 is provided in the building. The hoistway 2 is a vertically long space spanning multiple floors. In this example, a machine room 3 is provided above the hoistway 2. The machine room 3 may be located adjacent to the hoistway 2 or in another location. The elevator 1 includes a hoisting machine 4, a main rope 5, a car 6, a counterweight 7, and a control panel 8.

[0013] The hoisting machine 4 is provided, for example, in the machine room 3. The hoisting machine 4 is a device that generates driving force. The hoisting machine 4 includes a drive sheave 9 that rotates by driving force generated by a motor (not shown).

[0014] The main ropes 5 are wound around the drive sheave 9. The main ropes 5 support the load of the car 6 on one side of the drive sheave 9. The main ropes 5 support the load of the counterweight 7 on the other side of the drive sheave 9.

[0015] One of the car 6 and counterweight 7 travels upward in the hoistway 2 so as to be wound up via the main rope 5 by the rotation of the drive sheave 9. At this time, the other of the car 6 and counterweight 7 travels downward in the hoistway 2. The car 6 is a device that transports passengers and others on board between multiple floors by traveling up and down the hoistway 2. The weight of the counterweight 7 is set in consideration of the balance between the load of the car 6 and the load of the counterweight 7 applied via the main rope 5 on both sides of the drive sheave 9.

[0016] The control panel 8 is provided in, for example, the machine room 3. The control panel 8 is a device that controls the operation of the elevator 1. The control panel 8 controls, for example, the up and down travel of the car 6.

[0017] Next, an example of the configuration of the control panel 8 will be described with reference to FIGS.

[0018] FIG. 2 is a top view of the control panel 8 according to the first embodiment.

[0019] The control panel 8 has, for example, a rectangular parallelepiped shape. A worker performing maintenance work on the control panel 8 faces, for example, the front of the control panel 8. The front-to-rear direction is a direction in a horizontal plane perpendicular to the up-down direction. The left-to-right direction is a direction perpendicular to the front-to-rear direction among directions perpendicular to the horizontal plane. The left-to-right direction is an example of the direction of the first axis. The front-to-rear direction is an example of the direction of the second axis.

[0020] FIG. 3 is a front view of the control panel 8 according to the first embodiment.

[0021] The control panel 8 has, for example, a rectangular parallelepiped shape that is long in the vertical direction. In this example, the control panel 8 can be separated into an upper control panel 10 and a lower control panel 11. Each of the upper control panel 10 and the lower control panel 11 has, for example, a rectangular parallelepiped shape. In this example, the width of the upper control panel 10 in the left-right direction is the same as the width of the lower control panel 11 in the left-right direction. In addition, the width of the upper control panel 10 in the front-to-rear direction is the same as the width of the lower control panel 11 in the front-to-rear direction.

[0022] FIG. 4 is a side view of the control panel 8 according to the first embodiment.

[0023] The upper control panel 10 and the lower control panel 11 are connected by a plurality of screws 12 on each of their left and right sides. One of the left and right sides of the control panel 8 is an example of a first side. The other of the left and right sides of the control panel 8 is an example of a second side. Each screw 12 may be a screw, a bolt, or other type of screw. The upper control panel 10 and the lower control panel 11 in this example are connected by four screws 12 on each of their left and right sides at washer portions 13 provided on each of their left and right sides.

[0024] Some of the multiple screws 12 connecting the upper control panel 10 and the lower control panel 11 are provided on the front side of a vertical plane V that passes through the center of gravity G of the control panel 8 and whose normal is the front-to-back direction. Other parts of the multiple screws 12 connecting the upper control panel 10 and the lower control panel 11 are provided on the rear side of the vertical plane V. On each of the left and right side surfaces of the control panel 8 in this example, two screws 12 are provided on the front side of the vertical plane V. The two screws 12 on the front side of the vertical plane V are spaced apart in the vertical direction. On each of the left and right side surfaces of the control panel 8 in this example, two screws 12 are provided on the rear side of the vertical plane V. The two screws 12 on the rear side of the vertical plane V are spaced apart in the vertical direction. Each screw 12 fastens and connects the upper control panel 10 and the lower control panel 11 in a corresponding fastening hole provided in a washer portion 13 or the like on the side surface of the control panel 8.

[0025] Handle holes 14 are provided on each of the left and right side surfaces of the control panel 8. The handle holes 14 are provided at positions including the vertical plane V. The handle holes 14 are provided, for example, in the washer portions 13. The handle holes 14 are holes that allow workers to hold on to them when transporting the control panel 8. The handle holes 14 are provided between a plurality of screws 12. In this example, the two screws 12 on the front side of the vertical plane V are positioned forward of the handle holes 14. Furthermore, the two screws 12 on the rear side of the vertical plane V are positioned rearward of the handle holes 14.

[0026] When replacing the control panel 8 or performing other maintenance work, a worker may manually carry the control panel 8 in the machine room 3 or the like. In this case, the worker may carry the control panel 8 by placing his / her hands in the handle holes 14; however, it may be difficult to use the handle holes 14 due to the size, depth, or shape of the handle holes 14, or the presence of structures, protrusions, or other obstructions near the handle holes 14. Also, there may be cases where the control panel 8 does not have handle holes 14. In such cases, the worker carries the control panel 8 using a carrier 15 (not shown in FIG. 4 ).

[0027] FIG. 5 is a top view of the carrier 15 according to the first embodiment.

[0028] The carrier 15 includes a first attachment portion 16, a second attachment portion 17, and a connection portion 18. The carrier 15 is attached to one of the left and right sides of the control panel 8. The worker performing the transporting work attaches one carrier 15 to each of the left and right sides of the control panel 8, and performs the transporting work of the control panel 8.

[0029] Each of the first mounting portion 16 and the second mounting portion 17 has a mounting surface 19 that contacts a side surface of the control panel 8. The first mounting portion 16 and the second mounting portion 17 have a portion that extends away from the mounting surface 19 in the left-right direction of the control panel 8. In this example, the first mounting portion 16 and the second mounting portion 17 are, for example, a plate material bent into an L shape. The mounting surface 19 is a surface on one side of the fold of the plate material. In the first mounting portion 16 and the second mounting portion 17, the surface on the other side of the fold of the plate material extends away from the control panel 8 in the left-right direction. In this example, the edges of each of the first mounting portion 16 and the second mounting portion 17 are chamfered.

[0030] The connection portion 18 is a portion that connects the first mounting portion 16 and the second mounting portion 17. The connection portion 18 is, for example, welded to the first mounting portion 16 and the second mounting portion 17. The connection portion 18 is, for example, provided between the first mounting portion 16 and the second mounting portion 17 at a position spaced apart from the side surface of the control panel 8 in the left-right direction. The connection portion 18 includes a first handle 20. The first handle 20 is provided at a position spaced apart from the side surface of the control panel 8 in the left-right direction. The first handle 20 is, for example, a portion of the connection portion 18 that extends in the front-rear direction between the first mounting portion 16 and the second mounting portion 17.

[0031] FIG. 6 is a front view of the carrier 15 according to the first embodiment.

[0032] The connecting portion 18 is, for example, a pipe material having a circular cross section perpendicular to the longitudinal direction. The connecting portion 18 may be hollow, for example, to reduce weight, or may be solid, for strength.

[0033] FIG. 7 is a side view of the carrier 15 according to the first embodiment.

[0034] The first mounting portion 16 and the second mounting portion 17 are provided with mounting holes 21 that penetrate the mounting surface 19. In this example, the mounting holes 21 are provided at positions that are offset in the vertical direction with respect to the central axis A of the connection portion 18. The mounting holes 21 are also provided at positions that are offset in the vertical direction from the center of the mounting surface 19.

[0035] Next, an example of a method for transporting the control panel 8 using the carrier 15 will be described with reference to FIGS. FIG. 8 is a side view of control panel 8 to which carrier 15 according to the first embodiment is attached.

[0036] In a work location such as the machine room 3, a worker attaches the carrier 15 to the control panel 8 to be transported. The worker attaches two carriers 15 to the left and right side surfaces of the control panel 8.

[0037] First, the worker removes the screw 12 located in front of a vertical plane V including the center of gravity G of the control panel 8 on one of the left and right sides of the control panel 8. In this example, the worker removes the upper screw 12 of the two screws 12 located in front of the vertical plane V. The removed screw 12 and the fastening hole in which the screw 12 was attached are examples of a first screw and a first fastening hole. The worker also removes the screw 12 located behind the vertical plane V on the same side of the control panel 8. In this example, the worker removes the upper screw 12 of the two screws 12 located behind the vertical plane V. The removed screw 12 and the fastening hole in which the screw 12 was attached are examples of a second screw and a second fastening hole. The lower screws 12 on both sides of the vertical plane V remain attached as they are.

[0038] Next, the worker places the mounting surfaces 19 of the first and second mounting portions 16 and 17 of the carrier 15 against the side of the control panel 8 from which the screws 12 were removed. The first and second mounting portions 16 and 17 of the carrier 15 are shaped so as not to interfere with the lower screws 12 that remain. The worker aligns the mounting holes 21 of the carrier 15 with the two fastening holes from which the screws 12 were removed. For example, if it is difficult to align the mounting holes 21 and the fastening holes because the upper end of the first or second mounting portion 16 or 17 extends beyond the upper edge of the washer portion 13, the worker may flip the carrier 15 over. Because the mounting holes 21 are positioned vertically offset from the center of the mounting surface 19, flipping the carrier 15 over may prevent interference.

[0039] Next, the worker fastens the removed screws 12 into the mounting holes 21 of the first mounting portion 16 of the carrier 15 and the fastening holes of the control panel 8, thereby attaching the first mounting portion 16 of the carrier 15 to the side of the control panel 8. The worker also fastens the removed screws 12 into the mounting holes 21 of the second mounting portion 17 of the carrier 15 and the fastening holes of the control panel 8, thereby attaching the second mounting portion 17 of the carrier 15 to the side of the control panel 8. In this manner, the worker attaches the carrier 15 to one side of the control panel 8. Similarly, the worker attaches another carrier 15 to the other side of the control panel 8. Note that if the removed screws 12 are compatible with each other, screws 12 may be installed in the removed fastening holes and other fastening holes.

[0040] The removal of the screws 12 and the installation of the carriers 15 may be performed sequentially on the left and right sides of the control panel 8, or the screws 12 may be removed on both the left and right sides, and then the carriers 15 may be installed on both the left and right sides.

[0041] FIG. 9 is a top view of control panel 8 to which carrier 15 according to the first embodiment is attached.

[0042] The workers lift the control panel 8 by holding the first handles 20 of the carrier 15 attached to the left and right sides. In this example, the control panel 8 is lifted by two workers from both the left and right sides. The control panel 8 is transported to the work site while being lifted by the workers. Thereafter, the control panel 8 is placed at the installation site.

[0043] Thereafter, the worker removes the two screws 12 that were used to attach the carrier 15. The worker removes the carriers 15 from the left and right side surfaces of the control panel 8. The worker fastens the two removed screws 12 into their original fastening holes in the control panel 8. Note that if the removed screws 12 are compatible with each other, the screws 12 may be installed in the removed fastening holes and other fastening holes.

[0044] As described above, the carrier 15 according to the first embodiment is used to transport the control panel 8 of the elevator 1, which has a plurality of screws 12 on each of its two side surfaces, e.g., in the left-right direction. The carrier 15 includes a first mounting portion 16, a second mounting portion 17, and a connection portion 18. The first mounting portion 16 is attached to the side surface of the control panel 8 using a screw 12 provided on one side of a vertical plane V that passes through the center of gravity G of the control panel 8 and is perpendicular to the front-to-rear direction, at the position of a fastening hole where the screw 12 was provided. The second mounting portion 17 is attached to the side surface of the control panel 8 using a screw 12 provided on the other side of the vertical plane V, at the position of a fastening hole where the screw 12 was provided. The connection portion 18 connects the first mounting portion 16 and the second mounting portion 17. The connection portion 18 has a first handle 20 located at a position separated from the side surface of the control panel 8 in the left-to-right direction. With this configuration, it is possible to add gripping points to the control panel 8, which is a large, heavy object, using existing fastening holes and screws 12, making it easier to transport the control panel 8 manually, even in a small space such as a machine room 3. This reduces the workload on workers and improves the workability of the transport work. In addition, because the carrier 15 is attached to the control panel 8 using existing fastening holes and screws 12, no processing of the control panel 8 is required.

[0045] Furthermore, the first mounting portion 16 and the second mounting portion 17 do not interfere with other screws 12 that are used when attaching the carrier 15 to the control panel 8. This minimizes the need for work such as removing the screws 12, making it less likely that the workability of the transportation work will be reduced. Furthermore, workers will be able to attach the carrier 15 to the control panel 8 while leaving the other screws 12 attached. Therefore, even if the control panel 8 can be separated into an upper control panel 10 and a lower control panel 11, for example, and are connected with multiple screws 12, the strength of the control panel 8 can be maintained during transportation.

[0046] Furthermore, when handle holes 14 are provided on the side of control panel 8, first mounting portion 16 is attached to one side of handle hole 14 in the front-to-rear direction, and second mounting portion 17 is attached to the other side of handle hole 14 in the front-to-rear direction. Even if it is difficult to use handle holes 14 in control panel 8 due to the shape of handle hole 14 or the presence of an obstructing object nearby, carrier 15 can be used to add a gripping point to control panel 8, thereby further improving the workability of transport work. Furthermore, carrier 15 is positioned so as to straddle handle hole 14, so that the range before and after the position of handle hole 14, including its position, can be gripped. This increases the degree of freedom in the gripping position and gripping posture, and further improves the workability of transport work.

[0047] The elevator 1 to which the control panel 8 transported using the transport device 15 is applied is not limited to a 1:1 roping elevator. Also, the elevator 1 to which the control panel 8 transported using the transport device 15 is applied is not limited to a traction elevator, but may be a hydraulic or other type of elevator.

[0048] FIG. 10 is a side view of a main part of a first modified example of the carrier 15 according to the first embodiment.

[0049] Instead of the mounting holes 21, the first mounting portion 16 and the second mounting portion 17 of the carrier 15 may be provided with potbelly holes 22 or the like. The potbelly holes 22 may be, for example, elongated holes or circular holes with a diameter larger than the width of the elongated holes. The diameter of the circular hole portion of the potbelly holes 22 is larger than the diameter of the heads of the screws 12 on the control panel 8. The width of the elongated hole portion of the potbelly holes 22 is smaller than the diameter of the heads of the screws 12 and larger than the diameter of the threaded portions of the screws 12. The elongated hole portion of the potbelly holes 22 is positioned below the circular hole portion. By providing the potbelly holes 22 in this manner, a worker can attach the carrier 15 to the control panel 8 without completely removing the screws 12 from the control panel 8. Furthermore, because the elongated hole portion of the potbelly holes 22 faces downward, the screws 12 engage in the elongated hole portion when the control panel 8 is lifted, thereby more stably connecting the carrier 15 and the control panel 8.

[0050] FIG. 11 is a side view of a main part of a second modified example of the carrier 15 according to the first embodiment.

[0051] Notches 23 may be provided in place of the mounting holes 21 in the first mounting portion 16 and the second mounting portion 17 of the carrier 15. The width of the notches 23 is smaller than the diameter of the heads of the screws 12 and larger than the diameter of the threaded portions of the screws 12. The notches 23 are provided to extend downward from the upper edges of the first mounting portion 16 and the second mounting portion 17. By providing the notches 23 in this manner, a worker can attach the carrier 15 to the control panel 8 without completely removing the screws 12 from the control panel 8.

[0052] FIG. 12 is a top view of a third modified example of the carrier 15 according to the first embodiment.

[0053] In the carrier 15, the first mounting portion 16, the second mounting portion 17, and the connecting portion 18 may be separable from one another. In this example, the connecting portion 18 is secured by passing bolts 24 provided at both ends of the first handle 20 through holes provided in the first mounting portion 16 and the second mounting portion 17 and fastening them with nuts 25. The first mounting portion 16, the second mounting portion 17, and the connecting portion 18 can be separated by removing the nuts 25. Furthermore, in the carrier 15, the front-to-rear distance between the first mounting portion 16 and the second mounting portion 17 can be adjusted by adjusting the fastening position of the nuts 25. Since the carrier 15 can be separated into multiple components, the carrier 15 becomes easier to transport and is more convenient for maintenance workers. Furthermore, because the front-to-rear distance between the first mounting portion 16 and the second mounting portion 17 is adjustable, a single type of carrier 15 can be used for control panels 8 with a wider variety of specifications.

[0054] Embodiment 2 In the second embodiment, differences from the example disclosed in the first embodiment will be described in particular detail. For features not described in the second embodiment, any of the features of the example disclosed in the first embodiment may be adopted.

[0055] FIG. 13 is a top view of the main part of a carrier 15 according to the second embodiment.

[0056] The connection part 18 has extension handles 26 extending in the front-rear direction at both ends of the first handle 20 in the front-rear direction. The extension handles 26 are rod-shaped members or the like that are attached to the outside of the first mounting part 16 and the second mounting part 17 in the front-rear direction. The extension handles 26 may be separable from the first handle 20 or the like, or may be provided integrally with the first handle 20 and the first mounting part 16 and the second mounting part 17. The extension handles 26 are connected, for example, by being fastened to the bolt part 24. The length of the connection part 18 in the front-rear direction, including the extension handles 26, is longer than the width of the control panel 8 in the front-rear direction.

[0057] FIG. 14 is a top view of control panel 8 to which carrier 15 according to the second embodiment is attached.

[0058] The workers lift the control panel 8 by holding the first handle 20 and the extension handle 26 of the carrier 15 attached to the left and right sides. In this example, the control panel 8 is lifted by a total of four workers, two on each side. The control panel 8 is transported to the work site while being lifted by the workers. The control panel 8 is then placed at the installation site.

[0059] In this way, by providing the extension handle 26, multiple workers can carry the control panel 8 side by side from the same left and right side. This makes it easier to carry even a heavy control panel 8.

[0060] Embodiment 3 In the third embodiment, differences from the examples disclosed in the first or second embodiment will be described in particular detail. For features not described in the second embodiment, any of the features of the examples disclosed in the first or second embodiment may be adopted.

[0061] FIG. 15 is a top view of the main part of a carrier 15 according to the third embodiment.

[0062] The connection portion 18 has second handles 27 at both ends of the first handle 20 in the front-rear direction. The second handles 27 are, for example, L-shaped rod-shaped members attached to the outer sides of the first mounting portion 16 and the second mounting portion 17 in the front-rear direction. The second handles 27 are bent at their front-rear direction ends toward the control panel 8 in the left-right direction. The second handles 27 may be separable from the first handle 20 or the like, or may be integral with the first handle 20 and the first and second mounting portions 16 and 17. The second handles 27 are connected, for example, by fastening to the bolt portions 24. The front-rear direction length of the connection portion 18 including the second handles 27 is longer than the front-rear direction width of the control panel 8. The left-right direction length of the second handle 27 is longer than the distance from the side of the control panel 8 to which the carrier 15 is attached to the first handle 20. That is, the tip of the second handle 27 is disposed in front of or behind the front or rear of the control panel 8.

[0063] FIG. 16 is a top view of a control panel 8 to which a carrier 15 according to the third embodiment is attached.

[0064] The workers lift the control panel 8 by holding the first handle 20 and the second handle 27 of the carrier 15 attached to the left and right sides. In this example, the control panel 8 is lifted by a total of four workers, one on each side (front, back, left, and right). The control panel 8 is transported to the work site while being lifted by the workers. The control panel 8 is then placed at the installation site.

[0065] In this way, by providing second handles 27, it becomes possible for multiple workers to carry control panel 8 by surrounding it from all sides. This makes it easier to carry even a heavy control panel 8 more stably. [Industrial Applicability]

[0066] The transporting device and transporting method according to the present disclosure can be applied to transporting elevator control panels. [Explanation of symbols]
