[0030] The embodiments for implementing this disclosure will be described with reference to the accompanying drawings. In the drawings, identical or equivalent parts are labeled with the same reference numerals, and repetitive descriptions are appropriately simplified or omitted. Furthermore, the scope of this disclosure is not limited to the following embodiments; any modifications to the constituent elements of the embodiments, or the omission of any constituent elements of the embodiments, are possible without departing from the spirit of this disclosure.

[0031] Implementation method 1.

[0032] Figure 1 This is a structural diagram of elevator 1 according to implementation method 1.

[0033] Elevator 1 is used in buildings with multiple floors. A shaft 2 is provided within the building. The shaft 2 is a long space extending vertically and spanning multiple floors. In this example, a machine room 3 is located above the shaft 2. The machine room 3 can also be located adjacent to the shaft 2 or in another location. Elevator 1 includes a traction machine 4, main ropes 5, a car 6, a counterweight 7, and a control panel 8.

[0034] The traction machine 4 is installed, for example, in a machine room 3. The traction machine 4 is a device that generates driving force. The traction machine 4 has a drive pulley 9 that rotates by the driving force generated by a motor (not shown).

[0035] The main rope 5 is wound around the drive sheave 9. The main rope 5 supports the load of the car 6 on one side of the drive sheave 9. The main rope 5 supports the load of the counterweight 7 on the other side of the drive sheave 9.

[0036] One of the car 6 and the counterweight 7 travels upward in the hoistway 2 by being wound up via the main rope 5 through the rotation of the drive sheave 9. Meanwhile, the other of the car 6 and the counterweight 7 travels downward in the hoistway 2. The car 6 is a device that transports passengers between multiple floors by traveling vertically within the hoistway 2. The weight of the counterweight 7 is set considering the balance between the load on the car 6 applied to both sides of the drive sheave 9 via the main rope 5 and the load on the counterweight 7.

[0037] The control panel 8 is installed, for example, in the machine room 3. The control panel 8 is a device that controls the operation of the elevator 1. For example, the control panel 8 controls the vertical movement of the car 6.

[0038] Next, use Figures 2 to 4 An example of the structure of control panel 8 will be given.

[0039] Figure 2 This is a top view of the control panel 8 in Embodiment 1.

[0040] The control panel 8 is, for example, rectangular in shape. The operator performing maintenance work on the control panel 8 faces, for example, the front surface of the control panel 8. The front-back direction is a direction within a horizontal plane perpendicular to the up-down direction. The left-right direction is a direction within a horizontal plane perpendicular to the front-back direction. The left-right direction is an example of the direction of the first axis. The front-back direction is an example of the direction of the second axis.

[0041] Figure 3 This is the front view of the control panel 8 in Implementation Method 1.

[0042] The control panel 8 is, for example, a rectangular parallelepiped shape with a longer vertical dimension. In this example, the control panel 8 can be separated into an upper control panel 10 and a lower control panel 11. The upper control panel 10 and the lower control panel 11 are each, for example, rectangular parallelepiped shapes. In this example, the left-right width of the upper control panel 10 is the same as the left-right width of the lower control panel 11. Furthermore, the front-back width of the upper control panel 10 is the same as the front-back width of the lower control panel 11.

[0043] Figure 4 This is a side view of the control panel 8 in Embodiment 1.

[0044] The upper control panel 10 and the lower control panel 11 are connected on their left and right sides by multiple screws 12. 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 can be a screw, bolt, or other type of screw. In this example, the upper control panel 10 and the lower control panel 11 are connected on their left and right sides by four screws 12 at the pad portions 13 respectively located on the left and right sides.

[0045] A portion of the screws 12 connecting the upper control panel 10 and the lower control panel 11 are located on the front side of a vertical plane V passing through the center of gravity G of the control panel 8 and with the front-to-back direction as the normal. Another portion of the screws 12 connecting the upper control panel 10 and the lower control panel 11 are located on the rear side of the vertical plane V. In this example, two screws 12 are provided on the front side of the vertical plane V on each of the left and right sides of the control panel 8. The two screws 12 on the front side of the vertical plane V are spaced apart vertically. In this example, two screws 12 are provided on the rear side of the vertical plane V on each of the left and right sides of the control panel 8. The two screws 12 on the rear side of the vertical plane V are spaced apart vertically. Each screw 12 secures the upper control panel 10 and the lower control panel 11 by fitting into corresponding fastening holes in the pad portion 13, etc., provided on the side of the control panel 8.

[0046] Handle holes 14 are provided on the left and right sides of the control panel 8. The handle holes 14 are located at positions including the vertical plane V. For example, the handle holes 14 are located in the pad portion 13. The handle holes 14 are designed so that operators can hook their hands when moving the control panel 8. The handle holes 14 are located among 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. Additionally, the two screws 12 on the rear side of the vertical plane V are positioned rearward of the handle holes 14.

[0047] During the replacement of control panel 8 and other maintenance work, sometimes personnel manually move control panel 8 in machine room 3 or similar locations. In this case, personnel can hook their hands onto handle hole 14 to move control panel 8, but due to the size, depth, or shape of handle hole 14, or the presence of nearby structures, protrusions, or other interfering objects, it is sometimes difficult to utilize handle hole 14. Additionally, there are cases where control panel 8 does not have handle hole 14. In such situations, personnel use... Figure 4 The transport tool 15 (not shown in the figure) is used to transport the control panel 8.

[0048] Figure 5 This is a top view of the transport tool 15 according to Embodiment 1.

[0049] The handling tool 15 includes a first mounting part 16, a second mounting part 17, and a connecting part 18. The handling tool 15 is mounted on one of the left or right sides of the control panel 8. The operator performing the handling operation mounts one handling tool 15 on each of the left and right sides of the control panel 8 to perform the handling operation.

[0050] The first mounting portion 16 and the second mounting portion 17 each have a mounting surface 19 that contacts the side of the control panel 8. Both the first mounting portion 16 and the second mounting portion 17 have portions that extend away from the mounting surface 19 in a left-right direction from the control panel 8. In this example, the first mounting portion 16 and the second mounting portion 17 are made of sheet metal bent into an L-shape, etc. The mounting surface 19 is the surface on one side of the crease of the sheet metal. In the first mounting portion 16 and the second mounting portion 17, the surface on the other side of the crease of the sheet metal extends away from the control panel 8 in a left-right direction. In this example, the edges of each of the first mounting portion 16 and the second mounting portion 17 are chamfered.

[0051] The connecting portion 18 connects the first mounting portion 16 and the second mounting portion 17. The connecting portion 18 is, for example, welded to the first mounting portion 16 and the second mounting portion 17. The connecting portion 18 is, for example, positioned between the first mounting portion 16 and the second mounting portion 17 at a location that extends from the side of the control panel 8 in the left-right direction. The connecting portion 18 includes a first handle 20. The first handle 20 is positioned at a location that extends from the side of the control panel 8 in the left-right direction. The first handle 20 is, for example, a portion of the connecting portion 18 that extends in the front-back direction between the first mounting portion 16 and the second mounting portion 17.

[0052] Figure 6 This is the front view of the transport tool 15 according to embodiment 1.

[0053] The connecting part 18 is, for example, a tube with a circular cross-section perpendicular to the length direction. The connecting part 18 can be hollow for the purpose of weight reduction or solid for the purpose of strength.

[0054] Figure 7 This is a side view of the transport tool 15 according to Embodiment 1.

[0055] In both the first mounting portion 16 and the second mounting portion 17, a mounting hole 21 is provided that penetrates the mounting surface 19. In this example, the mounting hole 21 is located at a position offset from the central axis A of the connecting portion 18 in the vertical direction. Furthermore, the mounting hole 21 is located at a position offset from the center of the mounting surface 19 in the vertical direction.

[0056] Next, use Figure 8 and Figure 9 An example of a transport method using the control panel 8 of the transport tool 15 will be explained.

[0057] Figure 8 This is a side view of the control panel 8 on which the handling tool 15 of Embodiment 1 is installed.

[0058] In work areas such as computer room 3, the operators install the handling tools 15 on the control panel 8 to be moved. The operators install two handling tools 15 on the left and right sides of the control panel 8.

[0059] First, the operator removes the screws 12 on the left and right sides of the control panel 8, which are located forward of the vertical plane V containing the center of gravity G of the control panel 8. In this example, the operator removes the upper screw 12 of the two screws 12 located forward of the vertical plane V. The removed screw 12 and the fastening hole for installing the screw 12 are examples of the first screw and the first fastening hole. Next, the operator removes the screws 12 on the same side of the control panel 8, which are located backward of the vertical plane V. In this example, the operator removes the upper screw 12 of the two screws 12 located backward of the vertical plane V. The removed screw 12 and the fastening hole for installing the screw 12 are examples of the second screw and the second fastening hole. On both sides of the vertical plane V, the lower screws 12 remain installed.

[0060] Next, the operator brings the mounting surfaces 19 of the first mounting portion 16 and the second mounting portion 17 of the handling tool 15 into contact with the side of the control panel 8 from which the screws 12 have been removed. Furthermore, the first mounting portion 16 and the second mounting portion 17 of the handling tool 15 are shaped to avoid interference with any remaining screws 12 on the lower side. The operator aligns the mounting hole 21 of the handling tool 15 with the two fastening holes from which the screws 12 have been removed. For example, if the upper end of the first mounting portion 16 or the second mounting portion 17 protrudes from the upper edge of the pad portion 13, making alignment of the mounting hole 21 and the fastening holes difficult, the operator can also reverse the orientation of the handling tool 15. Since the mounting hole 21 is located offset from the center of the mounting surface 19 in the vertical direction, interference can sometimes be avoided by reversing the orientation of the handling tool 15.

[0061] Next, the operator installs the first mounting portion 16 of the transport tool 15 onto the side of the control panel 8 by tightening the removed screws 12 into the mounting holes 21 of the first mounting portion 16 of the transport tool 15 and the fastening holes of the control panel 8. Similarly, the operator installs the second mounting portion 17 of the transport tool 15 onto the side of the control panel 8 by tightening the removed screws 12 into the mounting holes 21 of the second mounting portion 17 of the transport tool 15 and the fastening holes of the control panel 8. Thus, the operator installs the transport tool 15 on one side of the control panel 8. Likewise, the operator installs other transport tools 15 on the other side of the control panel 8. Furthermore, if the removed screws 12 are interchangeable, they can also be installed in fastening holes other than the removed fastening holes.

[0062] In addition, the removal of screws 12 and the installation of handling tools 15 can be carried out on the left and right sides of the control panel 8 in sequence, or the handling tools 15 can be installed on the left and right sides after the screws 12 are removed from the left and right sides.

[0063] Figure 9 This is a top view of the control panel 8 on which the handling tool 15 of embodiment 1 is installed.

[0064] The operator holds the first handle 20 of the handling tool 15 installed on the left and right sides and lifts the control panel 8. In this example, two operators lift the control panel 8 from the left and right sides. The control panel 8 is moved around the work site while being lifted by the operators. Then, the control panel 8 is placed at the installation location.

[0065] Then, the operator removes the two screws 12 from which the handling tool 15 is installed. The operator removes the handling tool 15 from the left and right sides of the control panel 8. The operator then tightens the two removed screws 12 into the original fastening holes of the control panel 8. Alternatively, if the removed screws 12 are interchangeable, they can be installed in fastening holes other than the removed fastening holes.

[0066] As described above, the handling tool 15 of Embodiment 1 is used to handle the control panel 8 of an elevator 1, which has multiple screws 12 on its sides in the left-right direction and other directions. The handling tool 15 includes a first mounting part 16, a second mounting part 17, and a connecting part 18. The first mounting part 16 is located on the side of the control panel 8 and is installed in the fastening hole of a screw 12 located 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-back direction. The second mounting part 17 is located on the side of the control panel 8 and is installed in the fastening hole of a screw 12 located on the other side of the vertical plane V. The connecting part 18 connects the first mounting part 16 and the second mounting part 17. The connecting part 18 has a first handle 20 located at a position away from the side of the control panel 8 in the left-right direction. With this structure, the existing fastening holes and screws 12 on the control panel 8, which is a large and heavy object, can be used to add a gripping part, so that the control panel 8 can be easily moved manually even in a small space such as the machine room 3. Therefore, it can reduce the workload of operators and further improve the operability of handling operations. In addition, the handling tool 15 is mounted on the control panel 8 using existing fastening holes and screws 12, so there is no need to process the control panel 8.

[0067] Furthermore, the first mounting part 16 and the second mounting part 17 do not interfere with screws 12 other than those used when mounting the handling tool 15 to the control panel 8. Therefore, the removal of screws 12 is minimized, thus minimizing the ease of handling. Additionally, the operator can mount the handling tool 15 to the control panel 8 with other screws 12 in place. Therefore, even if the control panel 8 can be separated into an upper control panel 10 and a lower control panel 11, etc., and connected by multiple screws 12, handling can be performed while maintaining the strength of the control panel 8.

[0068] Furthermore, when a handle hole 14 is provided on the side of the control panel 8, the first mounting part 16 is mounted on the side further back and forth than the handle hole 14, and the second mounting part 17 is mounted on the other side further back and forth than the handle hole 14. Even when the handle hole 14 is difficult to use due to its shape or the presence of nearby interference, the handling tool 15 can be attached to the control panel 8 for gripping, thus further improving the workability of the handling operation. In addition, the handling tool 15 is arranged to span the handle hole 14, so it can grip the area in front of and behind the handle hole 14. Therefore, the degree of freedom in gripping position and gripping posture is increased, further improving the workability of the handling operation.

[0069] Furthermore, the elevator 1 using the control panel 8 for moving materials via the handling tool 15 is not limited to a 1:1 rope-winding elevator. Additionally, the elevator 1 using the control panel 8 for moving materials via the handling tool 15 is not limited to a traction elevator; it can also be a hydraulic elevator or other types of elevators.

[0070] Figure 10 This is a side view of the main part of a first variation of the transport tool 15 according to Embodiment 1.

[0071] In the first mounting portion 16 and the second mounting portion 17 of the handling tool 15, a keyhole-shaped hole 22 may be provided instead of a mounting hole 21. The keyhole-shaped hole 22 may consist of, for example, an elongated hole and a circular hole with a diameter larger than the width of the elongated hole. The diameter of the circular portion of the keyhole-shaped hole 22 is larger than the diameter of the head of the screw 12 on the control panel 8. The width of the elongated portion of the keyhole-shaped hole 22 is smaller than the diameter of the head of the screw 12, but larger than the diameter of the threaded portion of the screw 12. The elongated portion of the keyhole-shaped hole 22 extends downwards from the circular portion. By providing the keyhole-shaped hole 22 in this way, the operator can install the handling tool 15 onto the control panel 8 without completely removing the screw 12. Furthermore, since the elongated portion of the keyhole-shaped hole 22 faces downwards, the screw 12 is engaged in the elongated portion when the control panel 8 is lifted, making the connection between the handling tool 15 and the control panel 8 more stable.

[0072] Figure 11 This is a side view of the main part of a second variation of the transport tool 15 according to Embodiment 1.

[0073] In the first mounting portion 16 and the second mounting portion 17 of the handling tool 15, a notch 23 may be provided instead of a mounting hole 21. The width of the notch 23 is smaller than the diameter of the head of the screw 12 and larger than the diameter of the threaded portion of the screw 12. The notch 23 is provided such that it extends downward from the upper edge of the first mounting portion 16 and the second mounting portion 17. By providing the notch 23 in this way, the operator can install the handling tool 15 onto the control panel 8 without completely removing the screw 12 from the control panel 8.

[0074] Figure 12 This is a top view of a third variation of the transport tool 15 according to Embodiment 1.

[0075] In the handling tool 15, the first mounting part 16, the second mounting part 17, and the connecting part 18 can also be separated from each other. In this example, the bolts 24 provided at both ends of the first handle 20 are passed through the holes provided in the first mounting part 16 and the second mounting part 17 respectively, and are tightened with nuts 25, thereby fixing the connecting part 18. The first mounting part 16, the second mounting part 17, and the connecting part 18 can be separated by removing the nuts 25. In addition, in the handling tool 15, the front-to-back spacing between the first mounting part 16 and the second mounting part 17 can be adjusted by adjusting the tightening position of the nuts 25. The handling tool 15 can be separated into multiple parts, thereby making the handling tool 15 easier to move and further improving the convenience for maintenance personnel. In addition, since the front-to-back spacing between the first mounting part 16 and the second mounting part 17 can be adjusted, a single type of handling tool 15 can be used to handle a wider variety of control panels 8 and the like.

[0076] Implementation method 2.

[0077] In Embodiment 2, the differences from the example disclosed in Embodiment 1 are described in particular detail. Any feature not described in Embodiment 2 may be used from the example disclosed in Embodiment 1.

[0078] Figure 13 This is a top view of the main part of the transport tool 15 in Embodiment 2.

[0079] The connecting portion 18 has extension handles 26 extending in the front-rear direction at both ends of the first handle 20. The extension handles 26 are rod-shaped components or the like, mounted on the outer sides of the first mounting portion 16 and the second mounting portion 17 in the front-rear direction. The extension handles 26 can be detached from the first handle 20, or they can be integrally formed with the first handle 20, the first mounting portion 16, and the second mounting portion 17. The extension handles 26 are connected, for example, by fastening to bolt portions 24, etc. The length of the connecting portion 18 including the extension handles 26 in the front-rear direction is longer than the width of the control panel 8 in the front-rear direction.

[0080] Figure 14 This is a top view of the control panel 8 on which the handling tool 15 of embodiment 2 is installed.

[0081] The operators hold the first handle 20 and the extension handle 26 of the handling tool 15 installed on the left and right sides, and lift the control panel 8. In this example, the control panel 8 is lifted by four operators, two on each side. The control panel 8 is moved around the work site while being lifted by the operators. Then, the control panel 8 is placed at the installation location.

[0082] In this way, by providing the extended handle 26, multiple operators can move the control panel 8 side by side from the same side in both left and right directions. As a result, even the heavy control panel 8 is easier to move.

[0083] Implementation method 3.

[0084] In Embodiment 3, the differences from the examples disclosed in Embodiment 1 or Embodiment 2 are described in particular detail. Regarding features not described in Embodiment 2, any feature from the examples disclosed in Embodiment 1 or Embodiment 2 may be used.

[0085] Figure 15 This is a top view of the main part of the transport tool 15 in embodiment 3.

[0086] The connecting portion 18 has second handles 27 at both ends of the first handle 20 in the front-rear direction. The second handles 27 are rod-shaped components, for example, bent into an L-shape, mounted on the outer side of the first mounting portion 16 and the second mounting portion 17 in the front-rear direction. The ends of the second handles 27 bend towards the control panel 8 in the left-right direction. The second handles 27 can be separated from the first handle 20, or they can be integrally provided with the first handle 20, the first mounting portion 16, and the second mounting portion 17. The second handles 27 are connected, for example, by fastening to bolt portions 24. The length of the connecting portion 18 including the second handles 27 in the front-rear direction is longer than the width of the control panel 8 in the front-rear direction. The length of the second handles 27 in the left-right direction is longer than the distance from the side of the control panel 8 where the handling tool 15 is mounted to the first handle 20. That is, the ends of the second handles 27 are positioned at the front or back of the front or back of the control panel 8.

[0087] Figure 16 This is a top view of the control panel 8 on which the handling tool 15 of embodiment 3 is installed.

[0088] The operators, holding the first handle 20 and the second handle 27 of the handling tool 15 installed on the left and right sides, lift the control panel 8. In this example, four operators, one from each of the four directions (front, back, left, and right), lift the control panel 8. The control panel 8 is then moved around the work site while being lifted by the operators. Finally, the control panel 8 is placed at its designated location.

[0089] In this way, by setting up a second handle 27, the control panel 8 can be moved by multiple workers surrounding it from all sides. As a result, even the heavy control panel 8 can be moved more easily and stably.
