Patent Document 1 and Patent Document 2 disclose techniques for holding a lid removed from a container. When removing a lid from a container, the operator's hands (including gloved hands) come into contact with the container, the lid, or a fastening member such as a bolt that secures the lid to the container.

If there is no danger in touching the container, lid, or fastening member, there is no problem in the worker's hand coming into contact with the container, lid, or fastening member. On the other hand, when working with current flowing through the transformer inside the container, it is dangerous to touch the container, the lid, or the fastening members. Of course, there is no danger if the work is carried out with the current flowing through the transformer cut off as in the past, but in this case, work to cut off the current is required. Therefore, it cannot be said that the work efficiency is high. Alternatively or additionally, assume that the insulating oil in the container contains harmful substances such as PCB (polychlorinated biphenyls). In this case, it is dangerous to touch the container, lid or fastening member. Of course, if you work while wearing gloves, the risk is low, but the risk of harmful substances reaching your skin through gaps between the gloves and your work clothes cannot be completely eliminated.

(Embodiment)
An example of the fastening section 7, lid member 8, and container 9 handled in the embodiment will be described with reference to FIGS. 1 and 2. 1 and 2 are schematic perspective views schematically showing the fastening section 7, the lid member 8, and the container 9. Note that FIG. 1 shows a state in which the lid member 8 is in the closed position (in other words, the closed state of the lid member), and FIG. 2 shows a state in which the lid member 8 is in the open position (in other words, the state in which the lid member is in the closed state). open state).

In the example shown in FIG. 1, the lid member 8 is arranged to cover the opening of the container 9. Further, the lid member 8 is fixed to the container 9 by a fastening portion 7. In the example shown in FIG. 1, the fastening part 7 has a base part 71 fixed to the container 9, an engaging part 72 that can engage with the upper surface of the lid member 8, and acts on the base part 71 and the engaging part 72. A fastening member 70 for fixing the lid member 8 to the container 9 is provided. The fastening member 70 is, for example, a bolt such as an eye bolt. In the example shown in FIG. 1 , the fastening section 7 includes a base 71 , an engaging section 72 , and a fastening member 70 . Alternatively, the fastening section 7 may be composed only of a fastening member such as a bolt. For example, assume that the flange of the container is provided with a screw hole and the lid member is provided with a through hole. In this case, the lid member is attached to the container by inserting the shaft of the bolt into the through hole of the lid member and engaging the male thread provided on the bolt shaft with the screw hole (female thread) of the flange. It is possible to fix it to

In the example shown in FIG. 1, the fastening member 70 includes a second engaging portion 700 that can engage with a first engaging portion 31 of a remote control member, which will be described later. The second engaging portion 700 is, for example, a receiving portion (for example, a through hole portion 700h) that can receive the first engaging portion 31.

In the example shown in FIG. 1, the number of fastening parts 7 (or fastening members 70) is four, including a first fastening member 70-1, a second fastening member 70-2, a third fastening member 70-3, The lid member 8 is fixed to the container 9 by the fourth fastening member 70-4. Alternatively, the number of fastening parts 7 (or fastening members 70) may be one, two, three, or five or more.

When opening the opening 90 of the container 9, the fastening member 70 is loosened, and then the lid member 8 is moved to the open position. FIG. 2 shows the state after the four fastening members 70 have been loosened and the lid member 8 has been moved to the open position. In the example shown in FIG. 2, the engaging portion 72 of the fastening portion 7 (more specifically, the engaging portion 72 corresponding to the first fastening member 70-1) is completely separated from the lid member 8. . Further, in the example shown in FIG. 2, the engaging portion 72 corresponding to the second fastening member 70-2 and the engaging portion 72 corresponding to the third fastening member 70-3 are in a semi-separated state from the lid member 8. , the engaging part 72 corresponding to the fourth fastening member 70-4 is completely separated from the lid member 8 (the engaging part 72 corresponding to the fourth fastening member 70-4 is located on the back side of the container 9). (not shown in Figure 2). Alternatively, the engaging portions 72 corresponding to all the fastening members 70 may be completely separated from the lid member 8. Note that the semi-disengaged state means a state in which the engaging portion 72 is not engaged with the top surface of the lid member 8 but is located directly above the lid member 8, and the fully disengaged state is This means that the engaging portion 72 is not directly above the lid member 8.

A case is assumed in which insulating oil (or insulating oil and a transformer) is housed inside the container 9. In this case, when the lid member 8 is in the open state, it is possible to extract the insulating oil in the container 9 through the opening 90.

(First embodiment)
The remote control member 1 in the first embodiment will be described with reference to FIGS. 3 to 6. FIG. 3 is a schematic side view of the remote control member 1 in the first embodiment. FIG. 4 is a schematic plan view of the remote control member 1 in the first embodiment. FIG. 5 is a schematic perspective view of the remote control member 1 in the first embodiment. FIG. 6 is a diagram schematically showing how the fastening member 70 is loosened or tightened when the distal end portion 3 rotates relative to the base portion 2.

The remote control member 1 is a member used to loosen (or tighten) the fastening member 70. The fastening member 70 loosened (or loosened) by the remote control member 1 may be the fastening member 70 shown in FIGS. 1 and 2, or may be any other fastening member.

As shown in FIG. 3, the remote control member 1 includes a base 2 attached to the remote control rod MB and a tip 3.

In the example shown in FIG. 3, the base 2 of the remote control member 1 is removably attached to the remote control rod MB. Alternatively, the base 2 of the remote control member 1 may be non-removably attached to the remote control rod MB. A remote control tool 100 is configured by attaching the remote control member 1 to the remote control rod MB. The base 2 may be composed of one part or an assembly of a plurality of parts.

The distal end portion 3 includes a first engaging portion 31 that can be engaged with a fastening member 70 (see FIG. 1). As the shape of the tip portion 3 (and the first engaging portion 31), any shape can be adopted as long as it can be freely engaged with and detached from the fastening member 70. The tip portion 3 may be composed of one part or an assembly of a plurality of parts.

As shown in FIG. 1, a case is assumed in which the central axis AT1 of the through-hole portion 700h (second engagement portion 700) of the fastening member 70 is parallel to the horizontal plane. In this case, in the example shown in FIG. 3, the first engaging part 31 can be inserted into the through hole 700h by moving the first engaging part 31 in the horizontal direction.

As shown in FIG. 5, the first engaging portion 31 may include a distal end swollen portion 31d and a narrowed portion 31n that is thinner than the distal end swollen portion 31d. When the first engaging portion 31 includes the tip bulging portion 31d and the constricted portion 31n, the first engaging portion 31 may unintentionally become the second engaging portion 700 (more specifically, the through hole part 700h). Note that it is preferable that a stepped portion 31s be provided between the tip bulging portion 31d and the constricted portion 31n.

In the example shown in FIG. 3, the distal end portion 3 is rotatably connected to the base portion 2 around the first axis AX1. The distal end portion 3 is rotatable 360 degrees around the first axis AX1 with respect to the base portion 2. Therefore, by operating the remote control rod MB, the entire tip portion 3 can be continuously rotated around the first axis AX1 to quickly loosen (or tighten) the fastening member 70.

In the example shown in FIG. 6, when N is an arbitrary natural number of 1 or more, the distal end 3 rotates around the first axis AX1 with respect to the base 2 in the first rotation direction R1 (for example, clockwise when viewed from above). direction), the fastening member 70 (second engaging portion 700) engaged with the tip portion 3 (first engaging portion 31) rotates around the axis AT2 of the fastening member 70 in the first rotation direction (for example, This results in N rotations (clockwise when viewed from above). In this manner, by rotating the distal end portion 3 with respect to the base portion 2 multiple times, the fastening member 70 can be quickly tightened. Conversely, when the tip 3 rotates N around the first axis AX1 relative to the base 2 in the second rotation direction R2 (for example, counterclockwise when viewed from above), the tip 3 (first engaging portion 31), the fastening member 70 (second engaging portion 700) engaged with the fastening member 70 rotates N around the axis AT2 of the fastening member 70 in the second rotation direction (for example, counterclockwise when viewed from above). . In this way, by rotating the distal end portion 3 with respect to the base portion 2 multiple times, the fastening member 70 can be quickly loosened.

Note that the axial direction of the first axis AX1 is a direction different from the extending direction D1 of the remote control rod MB attached to the base 2. Therefore, by pushing and pulling the remote control rod MB in a direction different from the axial direction of the first axis AX1, the tip portion 3 can be rotated relative to the base portion 2. Therefore, a worker located on the side of the fastening member 70 can easily operate the remote control rod MB. From the viewpoint of allowing a worker located on the side of the fastening member 70 to easily operate the remote control rod MB, the angle between the first axis AX1 and the extending direction of the remote control rod MB is as follows. For example, the angle is 45 degrees or more and 90 degrees or less, 60 degrees or more and 90 degrees or less, or 60 degrees or more and 80 degrees or less. The angle between the first axis AX1 and the extending direction of the remote control rod MB may be a fixed angle that cannot be changed as shown in FIG. 3, or a variable angle that can be adjusted. You can.

In the example shown in FIG. 6, the axial direction of the first axis AX1 is parallel to the axial direction of the fastening member 70 (extending direction of the axis AT2). Therefore, by rotating the tip portion 3 around the first axis AX1, the fastening member 70 smoothly rotates around the axis AT2.

In the example shown in FIG. 3, the tip portion 3 includes a first portion 32 extending in a direction away from the first axis AX1, an intermediate portion 33 continuous to the first portion 32, and a second portion 34 continuous to the intermediate portion 33. include. The second portion 34 extends from the intermediate portion 33 in a direction approaching the first axis AX1. The second portion 34 includes the first engaging portion 31 described above. Since the distal end portion 3 includes the first portion 32, the intermediate portion 33, and the second portion 34 extending in the opposite direction to the first portion 32, the distal end portion 3 has a substantially U-shape as a whole. (In other words, it has a hook shape). Therefore, when the distal end portion 3 rotates around the first axis AX1, the possibility that the distal end portion 3 will fall off from the second engaging portion 700 of the fastening member 70 is reduced.

In the example shown in FIG. 3, the entire first portion 32 is located above the fastening member 70. Therefore, when the tip portion 3 rotates around the first axis AX1, the first portion 32 does not interfere with the fastening member 70. The first portion 32 is configured by, for example, a plate extending in a direction perpendicular to the first axis AX1.

In the example shown in FIG. 3, the intermediate portion 33 disengages the distal end 3 from the second engaging portion 700 of the fastening member 70 when the distal end 3 rotates around the first axis AX1. It functions as an engagement/disengagement prevention part to prevent this. The intermediate portion 33 is configured, for example, by a plate member extending in a direction parallel to the first axis AX1.

In the example shown in FIG. 3 , the second portion 34 functions as the first engaging portion 31 . The second portion 34 is configured, for example, by a plate extending in a direction perpendicular to the first axis AX1.

The first portion 32, the intermediate portion 33, and the second portion 34 may be formed by bending a single plate. In this case, since the first portion 32, the intermediate portion 33, and the second portion 34 are integrally formed, the strength of the tip portion 3 can be increased, and the manufacturing cost of the tip portion 3 can be reduced. Ru.

As shown in FIG. 3, the magnet 330 may be disposed on the intermediate portion 33 (more specifically, on the surface 33a of the intermediate portion 33 on the side farther from the first axis AX1). In this case, when the posture of the remote control member 1 is changed so that the first axis AX1 is parallel to the horizontal direction, the tip portion 3 rotates around the first axis AX1 due to its own weight, and the surface 33a and the magnet 330 are moved downward. facing. Therefore, the remote control member 1 (or the remote control tool 100) can be used as a magnetic material pulling member (or a magnetic material pulling tool). For example, FIG. 2 shows a state in which the engaging portion 72 corresponding to the first fastening member 70-1 is detached from the lid member 8. As shown in FIG. When the intermediate portion 33 includes a magnet 330, after returning the lid member 8 to the closed position, the remote control member 1 is pulled upward while the magnet 330 is attracted to the engaging portion 72, which is a magnetic material. This allows the engaging portion 72 to be pulled up above the lid member 8 (see the state shown in FIG. 1).

In the example shown in FIG. 3, the base 2 includes a remote control rod attachment part 21 to which the remote control rod MB is attached, and a tip end attachment part 22 extending from the remote operation rod attachment part 21 toward the distal end. The tip portion 3 is attached to the tip attachment portion 22 . In the example shown in FIG. 3 , the tip attachment portion 22 includes a first tip attachment portion 221 and a second tip attachment portion 222 .

The tip attachment portion first portion 221 is attached to the remote control rod attachment portion 21 via an arbitrary fastening member 24 (for example, a bolt BL and a nut Nu). The first portion 221 of the tip attachment portion is made of, for example, a plate material, and the normal line of the main surface 221a of the plate material is, for example, perpendicular to the first axis AX1.

The second portion 222 of the tip attachment portion is attached to the tip portion 3 via an arbitrary connecting member 25 (eg, bolt BL and nut Nu). The connecting member 25 connects the base 2 (more specifically, the second portion 222 of the tip attachment portion) and the tip 3 so that the tip 3 can rotate relative to the base 2. The second portion 222 of the tip attachment portion is made of, for example, a plate material, and the normal line of the main surface 222a of the plate material is, for example, parallel to the first axis AX1. Note that the second tip attachment portion 222 and the first tip attachment portion 221 may be formed by bending one plate material. In this case, since the second portion 222 of the tip attachment portion and the first portion 221 of the tip attachment portion are integrally formed, the strength of the tip attachment portion 22 can be increased, and the tip attachment portion 221 is integrally formed. The manufacturing cost of the section 22 is reduced.

In the example shown in FIG. 4, the longitudinal center axis AT3 of the second portion 222 of the tip attachment portion 222 and the longitudinal center axis AT4 of the remote control rod attachment portion 21 are eccentrically arranged with respect to each other in plan view. Therefore, when the operator looks at the tip portion 3, the remote control rod mounting portion 21 and the remote control rod MB are unlikely to get in the way.

In the example shown in FIG. 3, when maintaining the posture of the remote control member 1 such that the axial direction of the first axis AX1 is along the vertical direction, the central axis of the remote control rod attachment part 21 of the base 2 is Alternatively, it extends in a direction that is inclined upward in a range of greater than 0 degrees and less than 45 degrees with respect to the horizontal plane. In particular, when the central axis of the remote control rod attachment part 21 of the base 2 extends in a direction that is inclined upward, the fastening member 70 located below the operator's hand can be connected to the remote control member 1 (or When operating the fastening member 70 using the remote control tool 100), the operator can operate the fastening member 70 in a comfortable posture. Note that even if the angle formed between the horizontal plane (or the first axis AX1) and the central axis of the remote control rod attachment part 21 cannot be changed, the angle can be changed (in other words, the angle can be adjusted). It may be.

(Second embodiment)
The tool set SE1 in the second embodiment will be described with reference to FIGS. 7 to 9. FIG. 7 is a schematic side view schematically showing the tool set SE1 in the second embodiment. FIG. 8 is a schematic side view schematically showing the torque wrench 4 included in the tool set SE1. FIG. 9 is a schematic perspective view schematically showing the torque wrench 4 included in the tool set SE1.

In the example shown in FIG. 7, the tool set SE1 in the second embodiment includes a remote control member 1 and a torque wrench 4. As the remote control member 1 in the second embodiment, for example, the remote control member 1 in the first embodiment can be adopted. Since the remote control member 1 has already been explained in the first embodiment, repeated explanation of the remote control member 1 will be omitted.

In the example shown in FIG. 8, the torque wrench 4 includes a wrench base 41 attached to the remote control rod MB2, and a wrench tip 42 rotatably connected to the wrench base 41. The wrench tip portion 42 is rotatable relative to the wrench base portion 41 around the second axis AX2.

In the example shown in FIG. 8, the wrench base 41 of the torque wrench 4 is removably attached to the remote control rod MB2. Alternatively, the wrench base 41 of the torque wrench 4 may be irremovably attached to the remote control rod MB2. A remote control tool 200 is configured by attaching the torque wrench 4 to the remote control rod MB2. Wrench base 41 may be constructed from one piece or an assembly of multiple parts.

In the example shown in FIG. 8, the wrench base 41 of the torque wrench 4 includes a mounting portion 411 for attaching to the remote control rod MB2 and a connecting portion 412 for connecting to the wrench tip 42. In the example shown in FIG. 8, the attachment part 411 and the connection part 412 are fixed to each other so that the angle can be adjusted. In other words, the torque wrench 4 includes the angle adjustment mechanism AM, and the mounting portion 411 and the connection portion 412 are connected via the angle adjustment mechanism AM. Note that the angle adjustment mechanism AM may be omitted. When the angle adjustment mechanism AM is omitted, the angle formed between the mounting portion 411 and the connecting portion 412 is, for example, a fixed angle in the range of 0 degrees or more and 45 degrees or less.

The wrench tip portion 42 of the torque wrench 4 includes an engaging portion 421 that can engage with the fastening member 70 (see FIG. 1). Any shape can be adopted as the shape of the wrench tip portion 42 (and the engaging portion 421) as long as it can be freely engaged with and detached from the fastening member 70. Wrench tip 42 may be constructed from one piece or an assembly of multiple parts.

As shown in FIG. 1, it is assumed that the head of the fastening member 70 extends vertically upward. In this case, in the example shown in FIG. 8, the engaging part 421 can be engaged with the head of the fastening member 70 by moving the engaging part 421 vertically downward.

Assume that the fastening member 70 is tightened using the torque wrench 4. In the example shown in FIG. 8, when the torque required to tighten the fastening member 70 is less than the threshold value TH, when the wrench base 41 is rotated in the first rotation direction R1 around the second axis AX2, the wrench tip 42 is rotated. It rotates integrally with the wrench base 41 around the second axis AX2 in the first rotation direction R1. When the wrench tip 42 rotates in the first rotational direction, the fastening member 70 also rotates in the first rotational direction. In this way, the fastening member 70 is tightened. Note that the first rotation direction is, for example, a clockwise direction when viewed from above.

In the example shown in FIG. 8, when the torque required to tighten the fastening member 70 is equal to or higher than the threshold value TH, when the wrench base 41 is rotated in the first rotation direction R1 around the second axis AX2, the torque wrench 4 makes a noise. (For example, a "clack" sound), more specifically, a sound is generated that indicates that the tightening torque has reached the threshold value TH. Therefore, the operator can understand from the sound produced by the torque wrench 4 that the tightening torque has reached the threshold value TH, and can stop the tightening operation in response to the generation of the sound. In this way, the tightening torque of the fastening member 70 becomes the set torque corresponding to the threshold value TH.

It is preferable that the wrench base 41 (more specifically, the connection part 412) includes a threshold value operation part 415 that changes the above-mentioned threshold value TH. In the example shown in FIG. 8, the threshold value operation section 415 is a threshold value adjustment knob. For example, rotating the threshold adjustment knob clockwise increases (or decreases) the threshold TH, and rotating the threshold adjustment knob counterclockwise decreases (or increases) the threshold TH.

In the example shown in FIG. 8, the wrench base portion 41 (more specifically, the connecting portion 412) includes a threshold value indicating portion 417 that indicates the above-mentioned threshold value TH. For example, when the threshold value adjustment knob is rotated clockwise, the threshold value TH displayed on the threshold value indicator 417 is changed from "28Nm" to "30Nm" (or "44Nm"); When rotated, the threshold value TH displayed on the threshold value indicator 417 is changed from "44 Nm" to "30 Nm" (or "28 Nm").

Note that the change of the threshold value TH by the threshold value operation unit 415 may be configured to be performed in stages, or may be configured to be performed continuously.

The second embodiment has the same effects as the first embodiment. In addition, the tool set SE1 in the second embodiment includes a torque wrench 4. Therefore, it is possible to set the tightening torque of the fastening member 70 to a desired setting torque. More specifically, after quickly tightening the fastening member 70 using the remote control member 1, the torque wrench 4 is engaged with the fastening member 70 to further tighten the fastening member 70. In this way, the tightening torque of the fastening member 70 becomes the desired set torque.

Note that it is also possible to tighten the fastening member 70 using only the torque wrench 4 without using the remote control member 1. However, since tightening with the torque wrench 4 is generally performed by swinging motion of the torque wrench, it is difficult to quickly tighten the fastening member 70 in the initial stage of tightening. In addition, when tightening (or loosening) the fastening member 70 using only the torque wrench 4 without using the remote control member 1, the fastening member 70 follows the swinging motion of the torque wrench 4. (the rotation of the fastening member 70 in the tightening direction and the rotation of the fastening member 70 in the loosening direction may be repeated). On the other hand, since the tool set SE1 in the second embodiment includes the remote control member 1 and the torque wrench 4, it is possible to quickly loosen (or tighten) the fastening member 70 and tighten the fastening member 70. It is possible to simultaneously set the torque to a desired setting torque.

A remote control bar MB is attached to the remote control member 1 included in the tool set SE1 in the second embodiment, and another remote control bar MB2 is attached to the torque wrench 4 included in the tool set SE1. Good too. Alternatively, the remote control rod may not be attached to at least one of the remote control member 1 and the torque wrench 4. In this case, for example, the remote control rod MB may be attached to the remote control member 1 when the remote control member 1 is used, and the remote control rod MB2 may be attached to the torque wrench 4 when the torque wrench 4 is used. Further, the remote control rod MB attached to the remote control member 1 and the remote control rod MB2 attached to the torque wrench 4 may be the same remote control rod or may be different remote control rods. .

(Third embodiment)
The tool set SE2 in the third embodiment will be described with reference to FIGS. 10 to 17. FIG. 10 is a schematic side view schematically showing the tool set SE2 in the third embodiment. FIG. 11 is a diagram schematically showing a state in which the support member 52 of the open state maintenance tool 5 is in a support position that supports the load acting on the lid member 8. As shown in FIG. FIG. 12 is a diagram schematically showing a state in which the support member 52 of the open state maintaining tool 5 is in an unsupported position away from the support portion 91 of the container 9. FIG. 13 is a schematic side view schematically showing the open state maintaining tool 5 included in the tool set SE2. FIG. 14 is a schematic perspective view schematically showing the open state maintaining tool 5 included in the tool set SE2. FIG. 15 is a schematic side view schematically showing an example of the base member 6. As shown in FIG. FIG. 16 is a schematic plan view schematically showing an example of the base member 6. As shown in FIG. FIG. 17 is a schematic perspective view schematically showing an example of the base member 6. As shown in FIG.

In the example shown in FIG. 10, the tool set SE2 in the third embodiment includes a remote control member 1 and an open state maintenance tool 5. As the remote control member 1 in the third embodiment, for example, the remote control member 1 in the first embodiment can be adopted. Since the remote control member 1 has already been explained in the first embodiment, repeated explanation of the remote control member 1 will be omitted.

As shown in FIG. 11, the open state maintaining tool 5 is a tool that maintains the lid member 8 fixed to the container 9 by a fastening member in the open state. Note that in FIGS. 11 and 12, illustrations of fastening members are omitted.

In the example shown in FIG. 11, the open state maintaining tool 5 includes a lid member holding part 51 and a support member 52 connected to the lid member holding part 51. The lid member holding portion 51 is rotatable about the third axis AX3 with respect to the support member 52.

The lid member holding part 51 includes a magnet 510 that is attracted to the lid member 8. The magnet 510 is preferably attracted to the outer upper surface 8u of the lid member 8 or the outer side surface 8s of the lid member 8. In this case, even if a solution such as insulating oil is attached to the inner surface of the lid member 8, there is a low possibility that the solution will adhere to the lid member holding portion 51.

The support member 52 has a function of supporting the load (for example, gravity) acting on the lid member 8. In the example shown in FIGS. 11 and 12, the support member 52 is placed in a support position (a support position) where it contacts the support part 91 (support part for supporting the support member 52) of the container 9 and supports the load acting on the lid member 8. (see FIG. 11) and an unsupported position (see FIG. 12) where it is spaced apart from the support portion 91 of the container 9.

In the example shown in FIG. 11, the container 9 includes the support section 91, but the container 9 and the support section 91 may be separate bodies. For example, a base member 6 (see FIG. 15) functioning as a support may be attached to the container 9. In this case, the support member 52 can be changed in position between a support position in which it contacts the base member 6 and supports the load acting on the lid member 8 and a non-support position in which it is separated from the base member 6.

In the example shown in FIG. 11, the support member 52 includes a first portion 521 connected to the lid member holding portion 51 and extending in at least the first direction, and a second portion 521 extending in the second direction from the first portion 521. portion 522. Further, the angle α between the extending direction (first direction) of the first portion 521 and the extending direction (second direction) of the second portion 522 is, for example, 45 degrees or more and less than 90 degrees, and 60 degrees. The angle is greater than or equal to 90 degrees, or greater than or equal to 60 degrees and less than 85 degrees. In this case, when the support member 52 is placed on the support portion 91 (or the base member 6), the possibility that the support member 52 and the container 9 will interfere is reduced. Note that, as shown in FIG. 11, when the open state maintaining tool 5 maintains the lid member 8 in the open state, the support member 52 (more specifically, the second portion 522 of the support member 52) is preferably arranged so as to approach the container 9 as it goes downward. In the example shown in FIG. 11, the support member 52 has an inverted substantially L-shape when viewed from the side. Alternatively, the support member 52 may have a substantially U-shape when viewed from the side. Even when the support member 52 is approximately U-shaped in side view, the support member 52 and the container 9 may interfere with each other when the support member 52 is placed on the support portion 91 (or the base member 6). The possibility of

An example of the open state maintaining tool 5 will be described in further detail with reference to FIGS. 13 and 14.

In the example shown in FIG. 13, the lid member holder 51 includes a first magnet 510a that is attracted to the top surface of the lid member 8, and a second magnet 510b that is attracted to the side surface of the lid member 8. The angle between the lid member attraction surface S1 of the first magnet 510a and the lid member attraction surface S2 of the second magnet 510b is, for example, 90 degrees. The first magnet 510a and the second magnet 510b are attached to a magnet mount 513 (for example, an L-shaped member having an L-shaped cross section). Note that if the magnetic force of the first magnet 510a is sufficiently strong, the second magnet 510b may be omitted. Even in this case, it is preferable that the lid member holding part 51 includes an L-shaped member (more specifically, an L-shaped magnet fixture 513). Due to the presence of the L-shaped member, the positional relationship between the lid member holding portion 51 and the lid member 8 is maintained appropriately.

The lid member holding portion 51 includes a holding portion side connecting portion 515 connected to the supporting member 52. The holding part side connection part 515 is, for example, a bracket, and the magnet attachment 513 is attached to the holding part side connection part 515.

In the example shown in FIG. 14, the support member 52 (more specifically, the first portion 521) is connected to the third portion with respect to the lid member holding portion 51 (more specifically, the holding portion side connection portion 515). It is connected to be rotatable around the axis AX3. Since the lid member holding portion 51 is rotatable relative to the support member 52 around the third axis AX3, the inclination angle of the lid member holding portion 51 can be changed in accordance with the lifting of the lid member 8. It becomes possible to follow the inclination angle of the lid member 8.

In the example shown in FIG. 14, a gripped portion 526 that can be gripped by a gripping portion of a remote control tool is provided on the upper portion of the support member 52. More specifically, the support member 52 includes a gripped portion 526 above the third axis AX3. In the example shown in FIG. 14, the gripped portion 526 is constituted by a rod-shaped member parallel to the third axis AX3. By lifting the gripped portion 526 upward using a remote control tool, it is possible to lift the lid member 8 held by the lid member holding portion 51 upward.

In the example shown in FIG. 14, the first portion 521 of the support member 52 includes two plate members 521p, and the two plate members 521p are connected to each other via a connecting member CB. Then, the connecting member CB functions as the gripped portion 526.

In the example shown in FIG. 14, the plate material 521p is an L-shaped plate material, but the shape of the plate material 521p is not limited to the L-shape.

In the example shown in FIG. 14, the second portion 522 of the support member 52 is non-rotatably connected to the first portion 521 via the second connecting member CB2. The second portion 522 includes an upper end 522u connected to the second connecting member CB2, and a lower end 522b supported by a base member 6, etc., which will be described later.

In the example shown in FIG. 14, a gripped part 527 that can be gripped by a gripping part of a remote control tool is arranged on the lower part of the support member 52 (more specifically, the second part 522 of the support member 52). ing. In the example shown in FIG. 14, the gripped portion 527 includes a rod-shaped member 527b and a bracket 527a (for example, a U-shaped bracket) that attaches the rod-shaped member 527b to the second portion 522. By lifting the grasped portion 527 upward using a remote control tool, it is possible to lift the lid member 8 held by the lid member holding portion 51 upward. The bracket 527a is attached to the shaft member 520 that constitutes the support member 52.

In the state shown in FIG. 14, the longitudinal direction of the rod-shaped member 527b extends substantially vertically. However, in the example shown in FIG. 14, the gripped portion 527 is rotatably attached to the shaft member 520 (more specifically, rotatably around a pin member extending in a substantially horizontal direction). Therefore, the worker can change the posture of the gripped portion 527, in other words, the extending direction of the rod-shaped member 527b, depending on his/her standing position. Since the posture of the gripped part 527 can be changed, even if there are restrictions on the worker's standing position, the operator can change the posture of the gripped part 527 as appropriate, and then use the holding part of the remote control tool. The lid member 8 can be lifted by gripping the gripped portion 527. Furthermore, the gripped part 526 is arranged at the upper part of the open state maintenance tool 5, and the gripped part 527 is arranged at the lower part of the open state maintenance tool 5. Therefore, even if there are obstacles around the container 9 and the lid member 8, any one of the plurality of grasped parts can be selected to avoid the obstacle and the selected grasped part can be grasped. The gripping part can be lifted using the gripping part of the remote control tool.

In the example shown in FIG. 14, a first supported portion 522c that is supported in contact with a base member 6, etc., which will be described later, is arranged at a lower end 522b of the supporting member 52 (more specifically, the second portion 522). ing. The first supported portion 522c is, for example, a rod-shaped member B1 that protrudes perpendicularly to the shaft member 520 that constitutes the second portion 522. In the example shown in FIG. 14, two rod-shaped members B1 protrude from the shaft member 520 toward the outside of the shaft member 520.

In the example shown in FIG. 14, a second supported portion 522d that is contacted and supported by a base member 6, etc., which will be described later, is arranged at a lower end 522b of the supporting member 52 (more specifically, the second portion 522). ing. The second supported portion 522d is, for example, a rod-shaped member B2 that protrudes perpendicularly to the shaft member 520 that constitutes the second portion 522. In the example shown in FIG. 14, two rod-shaped members B2 protrude from the shaft member 520 toward the outside of the shaft member 520.

In the example shown in FIG. 14, the support member 52 includes a first supported part 522c and a second supported part 522d arranged above the first supported part 522c. Therefore, by selecting one of the first supported part 522c and the second supported part 522d and placing it on the base member 6, the inclination angle of the lid member 8, in other words, can be adjusted. It becomes possible to adjust the opening height between the lid member 8 and the container 9. For example, the opening height when the first supported part 522c is supported in contact with the base member 6 is greater than the opening height when the second supported part 522d is supported in contact with the base member 6.

(Base member 6)
Next, an example of the base member 6 attached to the container 9 will be described with reference to FIGS. 15 to 17.

In the example shown in FIG. 15, the base member 6 includes an attachment part 61 that is attached to the container 9, and a support part 62 that supports the open state maintenance tool 5 (more specifically, the support member 52 of the open state maintenance tool). Equipped with. The base member 6 may include a gripped portion 63 that can be gripped by a gripping portion of a remote control tool.

In the example shown in FIG. 16, the attachment part 61 includes a first magnet 610a that is attracted to a first region of the side wall of the container 9, and a second magnet 610b that is attracted to a second region of the side wall of the container 9. . The angle between the container attraction surface S3 of the first magnet 610a and the container attraction surface S4 of the second magnet 610b is, for example, 120 degrees or more and less than 180 degrees. The angle formed between the container suction surface S3 and the container suction surface S4 is set to correspond to the curvature of the outer surface of the container 9. In the example shown in FIG. 16, the angle between the container suction surface S3 and the container suction surface S4 cannot be changed, but the angle between the container suction surface S3 and the container suction surface S4 can be changed. It may be. In other words, the first magnet holding part that holds the first magnet 610a and the second magnet holding part that holds the second magnet 610b may be connected via a variable angle mechanism such as a hinge. Further, although FIG. 16 shows an example in which the attachment portion 61 includes a first magnet 610a and a second magnet 610b, the attachment portion 61 includes in addition to the first magnet 610a and the second magnet 610b. , a third magnet may be provided. In this case, the magnet holder that holds the first magnet 610a, the second magnet 610b, and the third magnet may have two hinge axes like a three-sided mirror.

In the example shown in FIG. 17, the support section 62 includes a first support section 621 and a second support section 622. In the example shown in FIG. 17, the first support portion 621 extends in a direction parallel to the direction from the mounting surface 61a of the mounting portion 61 toward the surface 61b on the opposite side to the mounting surface 61a. Similarly, the second support portion 622 extends in a direction parallel to the direction from the mounting surface 61a toward the opposite surface 61b. A space SP is provided between the first support part 621 and the second support part 622, which can receive a part of the shaft member 520 of the support member 52 described above.

The upper surface 621u of the first support part 621 and the upper surface 622u of the second support part 622 are surfaces with which the supported part (622c or 622d) of the support member 52 comes into contact.

The base member 6 may include a stopper member 65 that restricts movement (more specifically, movement in the horizontal direction) of the supported portion of the support member 52. The stopper member 65 may include a first stopper member 65a and a second stopper member 65b. In the example shown in FIG. 17, the bolt inserted into the support portion 62 functions as the first stopper member 65a. Further, in the example shown in FIG. 17, a block-shaped member fixed to the support portion 62 functions as the second stopper member 65b.

In the example shown in FIG. 17, the lower part of the base member 6 is provided with a gripped part 63 that can be gripped by a gripper of a remote control tool. In the example shown in FIG. 17, the gripped portion 63 is constituted by a rod-shaped member 63b arranged substantially horizontally. The attachment portion 61 of the base member 6 is attached to the container 9 by moving the grasped portion 63 in a direction toward the container using a remote control tool. The rod-shaped member 63b is attached to the attachment portion 61 or the support portion 62 via a bracket 63a that constitutes a part of the gripped portion 63.

The third embodiment has the same effects as the first embodiment. In addition, the tool set SE2 in the third embodiment includes an open state maintaining tool 5. Therefore, after loosening the fastening member 70 that fastens the lid member 8 and the container 9, it is possible to maintain the open state of the lid member 8 by supporting the lid member 8 using the open state maintaining tool 5. It is possible. In particular, when the open state maintaining tool 5 includes the lid member holding portion 51 and the support member 52, it is possible to maintain the open state of the lid member 8 with a simple operation. More specifically, by simply holding the lid member 8 by the lid member holding part 51 and then placing the support member 52 on the support part 91 of the container 9 or the base member 6 attached to the container 9, It is possible to maintain the open state of the lid member 8.

Note that when the support member 52 is placed on the base member 6 attached to the container 9, the tool set SE2 in the third embodiment includes, in addition to the remote control member 1 and the open state maintenance tool 5. , a base member 6 may be included. Alternatively or additionally, the tool set SE2 in the third embodiment may include the torque wrench 4 described in the second embodiment.

In addition, when using a member different from the remote control member 1 in the first embodiment as a member for loosening the fastening member 70 that fastens the lid member 8 and the container 9, the open state maintaining tool 5 It does not have to be a set with member 1. In other words, the open state maintaining tool 5 may be sold separately.

(Fourth embodiment)
A method of handling the lid member 8 and container 9 in the fourth embodiment will be described with reference to FIG. 18. FIG. 18 is a flowchart showing an example of a method for handling the lid member 8 and container 9 in the fourth embodiment.

The method of handling the lid member 8 and the container 9 in the fourth embodiment includes loosening the fastening member 70 that fastens the lid member 8 and the container 9.

In a first step ST1, a remote control tool 100 including a remote control member 1 and a remote control rod MB connected to the remote control member 1 is prepared. The remote control member 1 is, for example, the remote control member 1 in the first embodiment.

In the second step ST2, the remote control member 1 is engaged with the fastening member 70 that fixes the lid member 8 to the container 9. The second step ST2 is performed by engaging the distal end portion 3 of the remote control member 1 with the fastening member 70. More specifically, the second step ST2 is performed by inserting the first engaging portion 31 of the distal end portion 3 of the remote control member 1 into the second engaging portion 700 of the fastening member 70.

In the third step ST3, the fastening member 70 is loosened using the remote control tool 100. The third step ST3 includes rotating the entire tip portion 3 of the remote control member 1 by 360 degrees or more around the first axis AX1 with respect to the base portion 2 of the remote control member 1. By rotating the tip portion 3 one or more rotations relative to the base portion 2, the fastening member 70 is quickly loosened. Note that if the fastening member 70 is strongly tightened, the fastening member 70 may be loosened using the torque wrench 4 before the first step ST1, if necessary.

Note that the axial direction of the first axis AX1 is a direction different from the extending direction of the remote control rod MB. Therefore, for example, by reciprocating the remote control rod MB in a direction different from the vertical direction, it is possible to quickly loosen the fastening member 70 extending in the vertical direction.

After the fastening member 70 is loosened, an open state maintaining step of maintaining the lid member 8 in the open state may be performed in the fourth step ST4.

The open state maintaining process is performed using the open state maintaining tool 5. The open state maintaining tool 5 is, for example, the open state maintaining tool 5 described in the third embodiment. The open state maintaining tool 5 includes a lid member holder 51 including a magnet 510 that is attracted to the lid member 8, and a support member 52 rotatably connected to the lid member holder 51.

In the open state maintaining step, firstly, the magnet 510 of the lid member holding portion 51 is attracted to the lid member 8 . The step of attracting the magnet 510 to the lid member 8 is performed, for example, by operating an arbitrary remote control tool attached to the gripped portion (526, 527) of the open state maintaining tool 5. Second, the support member 52 of the open state maintaining tool 5 is placed on the support portion 91 of the container 9 or the base member 6 attached to the container 9 . More specifically, the support member 52 is moved from a non-support position where it is separated from the support part 91 or the base member 6 to a support position where it contacts the support part 91 or the base member 6 and supports the load acting on the lid member 8. By doing so, the support member 52 is placed on the support portion 91 or the base member 6.

The step of placing the support member 52 on the support part 91 or the base member 6 is performed, for example, by operating an arbitrary remote control tool attached to the gripped part (526, 527) of the open state maintenance tool 5. Ru. By placing the support member 52 on the support portion 91 or the base member 6, the open state of the lid member 8 is maintained.

In the fourth step ST4, the lid member holding part 51 of the open state maintenance tool 5 is attached to the lid member 8, and the support member 52 of the open state maintenance tool 5 is attached to the support part 91 of the container 9 or the base member attached to the container 9. This can be done by placing it on the 6. Therefore, the workload on the operator when executing the fourth step ST4 is small.

In addition, when the support member 52 is mounted on the base member 6 attached to the container 9, the process of attaching the base member 6 to the container 9 is performed before execution of 4th step ST4. In the step of attaching the base member 6, for example, the gripped portion 63 of the base member 6 is gripped by a gripping portion of an arbitrary remote control tool, and the base member 6 is moved in a direction toward the container using the remote control tool. It is executed by When the base member 6 approaches the container 9, the magnet of the attachment portion 61 of the base member 6 is attracted to the container 9.

After execution of the fourth step ST4, the solution (for example, insulating oil) in the container 9 may be extracted in the fifth step ST5. Since the lid member 8 is maintained in the open state by the open state maintenance tool 5, the workload on the operator when performing the fifth step ST5 is small. Note that the solution can be extracted using any solution extractor such as a pipette. The extracted solution is tested using any testing equipment.

After performing the fifth step ST5, a lid closing step of moving the lid member 8 to the closed position may be performed in the sixth step ST6. In the lid closing step, the support member 52 of the open state maintenance tool 5 is moved from a support position where it contacts the support part 91 of the container 9 or the base member 6 attached to the container 9 to a non-removal step that separates the support member 52 from the support part 91 or the base member 6. The process includes a step of moving to a supporting position and a step of removing the lid member holding part 51 of the open state maintaining tool 5 from the lid member 8.

After execution of the sixth step ST6, a fastening step of fastening the lid member 8 and the container 9 using the fastening member 70 may be performed.

As shown in FIG. 2, a case is assumed in which the engaging portion 72 of the fastening portion 7 is completely separated from the lid member 8. In this case, the engaging part 72 is pulled up onto the lid member 8 using the magnet 330 disposed at the intermediate portion 33 of the tip 3 of the remote control member 1 . More specifically, first, the magnet 330 at the tip 3 of the remote control member 1 is attracted to the engaging portion 72 . Thereafter, the engaging portion 72 is pulled up onto the lid member 8 by operating the remote control bar MB connected to the remote control member 1 to pull the magnet 330 upward.

After the engaging portion 72 is pulled up onto the lid member 8, the remote control member 1 is engaged with the fastening member 70 in a seventh step ST7. The seventh step ST7 is performed by engaging the distal end portion 3 of the remote control member 1 with the fastening member 70. More specifically, the seventh step ST7 is performed by inserting the first engaging portion 31 of the distal end portion 3 of the remote control member 1 into the second engaging portion 700 of the fastening member 70.

In the eighth step ST8, the fastening member 70 is tightened using the remote control tool 100. The eighth step ST8 includes rotating the entire tip portion 3 of the remote control member 1 by 360 degrees or more around the first axis AX1 with respect to the base portion 2 of the remote control member 1. The fastening member 70 is quickly tightened by rotating the distal end portion 3 one or more revolutions relative to the base portion 2.

In the ninth step ST9, the remote control member 1 is removed from the fastening member 70. The ninth step ST9 is performed by separating the distal end portion 3 of the remote control member 1 from the fastening member 70.

In the tenth step ST10, the torque wrench 4 is engaged with the fastening member 70. The tenth step ST10 is performed by engaging the wrench tip 42 of the torque wrench 4 with the fastening member 70. More specifically, the tenth step ST10 is performed by placing the wrench tip 42 over the head of the fastening member 70.

In the eleventh step ST11, the fastening member 70 is tightened using the torque wrench 4. The eleventh step ST11 is executed, for example, by swinging the remote control rod MB2 connected to the torque wrench 4. By executing the eleventh step, the tightening torque of the fastening member 70 becomes the desired set torque.

It is clear that the present invention is not limited to the above embodiments, and that the embodiments can be modified or changed as appropriate within the scope of the technical idea of the present invention. Further, any component used in each embodiment can be combined with other embodiments, and it is also possible to omit any component in each embodiment.

For example, in the above-described embodiment, an example has been described in which the distal end portion 3 of the remote control member 1 is freely rotatable around the first axis AX1 with respect to the base portion 2 of the remote control member 1. Alternatively, the remote control member 1 is switchable between a rotatable state in which the distal end 3 can freely rotate relative to the base 2 and a locked state in which the distal end 3 cannot rotate relative to the base 2. Good too. In this case, the remote control member 1 in the rotatable state can be used to loosen (or tighten) the fastening member 70, while the remote control member 1 in the locked state can be used for other purposes.

Furthermore, in the embodiments described above, magnet 330, magnet 510, and magnet 610 are permanent magnets. However, at least one of magnet 330, magnet 510, and magnet 610 may be an electromagnet.
