(First embodiment)
The first embodiment will be described below with reference to FIGS.

  FIG. 1 discloses a state in which a control panel 1 as an example of an apparatus is installed on a concrete base 2. The foundation 2 is covered with a floor 3 shown in FIG. The floor 3 has pits 3a constituting a wiring space.

  As shown in FIGS. 1 and 2, the control panel 1 includes, for example, a box-shaped housing 4 that houses various electric devices and cables, and a channel base 5 for installation. The housing 4 has a square bottom plate 4a, and fixing holes 6 are formed in four corners of the bottom plate 4a.

  The channel base 5 is configured by combining a plurality of channel materials. Specifically, the channel base 5 is formed in a square frame shape having a pair of long sides 5a and 5b and a pair of short sides 5c and 5d, and has a size corresponding to the bottom plate 4a of the housing 4. doing.

  As shown in FIGS. 2 and 4, the channel base 5 has a top plate 8, a bottom plate 9, and side plates 10. The top plate 8 and the bottom plate 9 are arranged in parallel with each other in the height direction of the channel base 5. The side plate 10 stands up so as to straddle between the outer edge of the top plate 8 and the outer edge of the bottom plate 9.

  The top plate 8 of the channel base 5 is overlaid on the lower surface of the bottom plate 4 a of the housing 4. Communication holes 11 are formed in the four corners of the top plate 8 respectively. The communication hole 11 is provided at a position corresponding to the fixing hole 6 of the housing 4.

  As shown in FIG. 3, bolts 12 are inserted into the fixing holes 6 of the housing 4 from above the bottom plate 4a. The bolt 12 passes through the communication hole 11 from the fixing hole 6, and a nut 13 is screwed into the through end of the bolt 12. As a result, the housing 4 and the channel base 5 are joined together to form an integral structure.

  As shown in FIGS. 2 and 4, four first insertion holes 14 are formed in the bottom plate 9 of the channel base 5. Two first insertion holes 14 are formed at positions corresponding to the long sides 5 a and 5 b of the channel base 5 in the bottom plate 9. The two first insertion holes 14 positioned on the long sides 5 a and 5 b are separated from each other in the longitudinal direction of the channel base 5. Further, the two first insertion holes 14 positioned on one long side 5a and the two first insertion holes 14 positioned on the other long side 5b are in a direction in which the short sides 5c and 5d extend. Are separated from each other along.

  In the present embodiment, the housing 4 and the channel base 5 are integratedly manufactured in the same factory, so the positions of the fixing hole 6 of the housing 4, the communication hole 11 of the channel base 5, and the first insertion hole 14 are accurate. It has been established.

  As shown in FIGS. 1 and 2, a gantry 16 for installing the control panel 1 is installed on the foundation 2. The gantry 16 is located in the pit 3a and exposed on the floor 3 from the pit 3a. The gantry 16 includes four legs 17 and a frame 18. The legs 17 are fixed on the foundation 2 and support the frame 18.

  The frame 18 is an element for supporting the channel base 5 of the control panel 1 from below, and has a square frame-shaped installation surface 19. The installation surface 19 has a size corresponding to the bottom plate 9 of the channel base 5. Four second insertion holes 20 are formed in the installation surface 19. The second insertion hole 20 corresponds to the first insertion hole 14 of the channel base 5, and matches the first insertion hole 14 when the channel base 5 is placed on the installation surface 19. It has become.

  As best shown in FIG. 4, bolts 21 are inserted into the first insertion holes 14 from above the bottom plate 9. The bolt 21 passes through the second communication hole 20 from the first insertion hole 14, and a nut 22 is screwed into the through end of the bolt 21. As a result, the channel base 5 is fixed to the frame 18 of the gantry 16.

  By the way, when the control panel 1 is fixed to the frame 18 of the gantry 16, after the control panel 1 is carried to the side of the gantry 16, the control panel 1 is lifted and placed on the installation surface 19 of the frame 18. When the control panel 1 is placed at a fixed position on the installation surface 19, the first insertion hole 14 of the channel base 5 matches the second insertion hole 20 of the frame 18. Thereby, the bolt 21 can be passed from the first insertion hole 14 toward the second insertion hole 20.

  However, since the gantry 16 is assembled at a place different from the factory that produces the control panel 1 such as a work site where the control panel 1 is installed, a dimensional error is likely to occur in each part of the gantry 16. For this reason, the accuracy of the second insertion hole 20 formed in the installation surface 19 deteriorates, and when the control panel 1 is placed on the installation surface 19, the first insertion hole 14 and the second insertion hole 20. There may be a gap between the two.

  In the first embodiment, before the control panel 1 is placed on the installation surface 19 of the gantry 16, the first insertion hole 14, the second insertion hole 20, The work which investigates whether the gap has arisen between is implemented.

  5 to 8 show the installation jig 30 used in the first embodiment. The installation jig 30 includes a metal jig body 31. The jig body 31 has a pair of guide rails 32a and 32b. The guide rails 32a and 32b are configured by straight belt-like plates, and the cross-sectional shape in the direction orthogonal to the longitudinal direction is a trapezoid. The guide rails 32 a and 32 b are overlapped with each other in the thickness direction, and are connected to each other via a single screw 33 and a nut 34. The screw 33 passes through a central portion along the longitudinal direction of the guide rails 32 a and 32 b, and a nut 34 is screwed into a through end of the screw 33. The nut 34 is preferably fixed to one guide rail 32a by means such as welding.

  According to the present embodiment, the guide rails 32 a and 32 b are rotatable between the storage position and the use position with the screw 33 as the center. In the retracted position, the guide rails 32a and 32b overlap each other over the entire length, and the jig body 31 is formed into a single straight bar. At the use position, the guide rails 32a and 32b cross each other, and the jig body 31 is developed in an X shape. The crossing angle α between the guide rails 32a and 32b can be adjusted steplessly by loosening the screw 33. Further, the guide rails 32 a and 32 b can be fixed at an arbitrary rotation position by tightening the screw 33.

  As shown in FIG. 5, a pair of holders 36 is supported on the guide rails 32a and 32b. Since the holders 36 have a common configuration, one holder 36 supported by one guide rail 32a will be described as a representative.

  As shown in FIGS. 6 and 7, the holder 36 is configured by a square block, and a guide hole 37 through which the guide rail 32 a penetrates is formed at the center. For this reason, the holder 36 is supported by the guide rail 32a so that it can slide along the longitudinal direction of the guide rail 32a.

  Further, the pair of holders 36 supported by the guide rail 32a are distributed in the longitudinal direction of the guide rail 32a with the screw 33 interposed therebetween. Therefore, the pair of holders 36 can slide linearly in a direction approaching or moving away from the screw 33.

  The holder 36 has a first surface 38a and a second surface 38b located on the opposite side of the first surface 38a. The first surface 38 a and the second surface 38 b are flat surfaces parallel to the guide rail 32 a, respectively, and are positioned on both sides along the thickness direction of the holder 36.

  Furthermore, the holder 36 has a screw hole 39. One end of the screw hole 39 is opened in the second surface 38 b of the holder 36. The other end of the screw hole 39 is opened in the guide hole 37.

  A lock screw 40, which is an example of a lock member, is screwed into the screw hole 39. The distal end 40 a of the lock screw 40 faces the guide rail 32 a inside the screw hole 39. When the lock screw 40 is loosened, the tip 40a of the lock screw 40 is separated from the guide rail 32a, so that the holder 36 can be freely slid along the longitudinal direction of the guide rail 32a.

  When the lock screw 40 is tightened, the tip 40a of the lock screw 40 abuts against the guide rail 32a. Therefore, the free slide of the holder 36 with respect to the guide rail 32a is limited, and the holder 36 can be fixed to the guide rail 32a at an arbitrary position along the longitudinal direction of the guide rail 32a.

  As shown in FIGS. 6 and 7, the holder 36 has a conical first protrusion 42 and a conical second protrusion 43. The first protrusion 42 is inserted into the first insertion hole 14 formed in the channel base 5, and protrudes perpendicularly from the first surface 38 a of the holder 36. The maximum outer diameter of the first protrusion 42 is larger than the diameter of the first insertion hole 14.

  The second protrusion 43 is inserted into the second insertion hole 20 formed on the installation surface 19 of the gantry 16, and is directed from the second surface 38 b of the holder 36 to the side opposite to the first protrusion 42. Projecting coaxially. In other words, the first protrusion 42 and the second protrusion 43 are arranged coaxially with respect to the common axis O1 orthogonal to the guide rail 32a. The maximum outer diameter of the second protrusion 43 is larger than the diameter of the second insertion hole 20.

  Further, a plurality of scales 44 are provided on the outer peripheral surface of the second protrusion 43. The scale 44 indicates the amount of insertion of the second protrusion 43 with respect to the second insertion hole 20. The scales 44 are arranged at equal intervals in the axial direction of the second protrusions 43 and are continuous in the circumferential direction of the second protrusions 43.

  FIG. 8 discloses a specific example of the scale 44 marked on the outer peripheral surface of the second protrusion 43. According to the present embodiment, the scale 44 corresponds to the diameter of the bolt 21 that is passed through the second insertion hole 20. Specifically, the scale 44 includes first to seventh scales 44a, 44b, 44c, 44d, 44e, 44f, and 44g corresponding to the seven types of bolts 21 from M12 to M24. For example, the first scale 44 a corresponds to the bolt 21 whose screw name is M12 and is positioned at the tip of the second protrusion 43. The seventh scale 44g corresponds to the bolt 21 whose screw name is M24, and is located in the vicinity of the root of the second protrusion 43. For this reason, the diameter of the second protrusion 43 increases as the first scale 44a progresses to the seventh scale 44g.

  Further, the first to seventh scales 44a to 44f are displayed in different colors. For example, when the outer peripheral surface of the second protrusion 43 is a silver color peculiar to metal, as shown in FIG. 8, the first scale 44a is brown, the second scale 44b is blue, the third scale 44c is white, The 4th scale 44d is yellow, the 5th scale 44e is green, the 6th scale 44f is black, and the 7th scale 44g is red.

  In this embodiment, the scale 44 is provided on the outer peripheral surface of the second protrusion 43, but the scale indicating the amount of insertion of the first protrusion 42 into the first insertion hole 14 is provided on the outer peripheral surface of the first protrusion 42. May be.

  Next, a method of using the installation jig 30 will be described with reference to FIGS.

  The control panel 1 carried to the side of the gantry 16 is lifted, and the first insertion hole 14 of the channel base 5 is exposed to the lower side of the control panel 1.

  In this state, the screw 33 of the jig body 31 is loosened to expand the guide rails 32a and 32b in an X shape, and the lock screws 40 of the four holders 36 are loosened to fix the holder 36 to the guide rails 32a and 32b. Is released.

  Next, the installation jig 30 is directed to the lower surface of the bottom plate 9 of the channel base 5, and the first protrusions 42 of the four holders 36 are equally inserted into the first insertion holes 14 of the channel base 5. As described above, the crossing angle α of the guide rails 32a and 32b and the position of the holder 36 with respect to the guide rails 32a and 32b are adjusted.

  After confirming that the first protrusions 42 of the four holders 36 are evenly inserted into the first insertion holes 14 of the channel base 5, the screws 33 are tightened to rotate the guide rails 32a and 32b relatively. Restrict. Further, the lock screw 40 of each holder 36 is tightened to fix the position of the holder 36 relative to the guide rails 32a and 32b.

  As a result, the first protrusion 42 of the installation jig 30 is fixed at a position that matches the first insertion hole 14 of the channel base 5, and the positional relationship of the first insertion hole 14 with the installation jig 30 is fixed. Remembered.

  Next, the installation jig 30 is removed from the channel base 5 and transferred to the installation surface 19 of the gantry 16. That is, as shown in FIG. 9, the installation jig 30 is placed on the installation surface 19, and the second protrusions 43 of the four holders 36 are opened in the installation surface 19. Insert them individually.

  At this time, if the second insertion holes 20 of the gantry 16 are accurately aligned with the first insertion holes 14 of the channel base 5, as shown in FIG. C1 and the center line C2 of the second insertion hole 20 coincide with each other. As a result, it can be seen that the four second protrusions 43 equally enter the four second insertion holes 20 and the position of the second insertion hole 20 is appropriate.

  On the other hand, if the position of the second insertion hole 20 is inappropriate, the center line C1 of at least one second protrusion 43 and the center line C2 of at least one second insertion hole 20 are shown in FIG. A gap g along the radial direction of the second insertion hole 20 occurs between For this reason, before the second protrusion 43 is inserted into the second insertion hole 20 to a predetermined depth, the outer peripheral surface of the second protrusion 43 contacts the opening edge of the second insertion hole 20, Insertion of the second protrusion 43 into the insertion hole 20 is prevented. The amount of the displacement g of the second insertion hole 20 can be generally grasped by reading the scale 44 on the outer peripheral surface of the second protrusion 43 that matches the opening edge of the second insertion hole 20.

  Although there is no direct association between the shift amount g of the second insertion hole 20 and the scale 44, for example, it is defined on the assumption that the diameter of the second insertion hole 20 uses a bolt 21 with M21. In this case, if the brown first scale 44a is located in the vicinity of the opening edge of the second insertion hole 20, it can be intuitively determined that the shift amount g is small.

  In the present embodiment, the first to seventh graduations 44a to 44g are displayed in different colors. For example, a screw designation is imprinted near the first to seventh graduations 44a to 44g without color coding. May be. However, by color-coding the first to seventh scales 44a to 44g, the relative positional relationship between the first to seventh scales 44a to 44g and the second insertion hole 20 can be recognized at a glance. . Therefore, there is an advantage that it is possible to easily confirm whether or not the position of the second insertion hole 20 is inappropriate even in a work environment with poor visibility.

  When it is determined by the installation jig 30 that the second insertion hole 20 is displaced from the normal position, the installation jig 30 is removed from the installation surface 19 of the gantry 16 and opened on the installation surface 19. The operation of correcting the opening shape of the two insertion holes 20 is executed.

  After the correction of the second insertion hole 20 is completed, the channel base 5 of the control panel 1 is placed on the installation surface 19 of the gantry 16, and the first insertion hole 14 of the channel base 5 and the second of the gantry 16 are placed. The insertion hole 20 is matched.

  Subsequently, the bolt 21 is inserted from the first insertion hole 14 toward the second insertion hole 20, and the nut 22 is screwed into the insertion end of the bolt 21. Thereby, the control panel 1 is fixed on the gantry 16, and the installation work of the control panel 1 is completed.

  After the installation jig 30 is used, the lock screw 40 is loosened and all the holders 36 are removed from the guide rails 32a and 32b. Further, the screw 33 is loosened to release the fixing of the guide rails 32a and 32b, and the guide rails 32a and 32b are rotated to the overlapping storage position over the entire length.

  According to the installation jig 30 of the first embodiment, the first protrusions 42 are evenly inserted into the first insertion holes 14 of the channel base 5 so that the position of the first insertion hole 14 is for installation. It can be stored in the jig 30. The installation jig 30 storing the position of the first insertion hole 14 is moved from the channel base 5 to the gantry 16 and the second protrusion 43 is inserted into the second insertion hole 20 of the gantry 16. Based on the mutual positional relationship between the projection 43 and the second insertion hole 20, it can be determined whether or not the second insertion hole 20 is displaced from the fixed position.

  For this reason, when the second insertion hole 20 is displaced from the fixed position, the second insertion hole 20 is corrected before the channel base 5 of the control panel 1 is overlaid on the installation surface 19 of the gantry 16. Can be migrated.

  Therefore, by placing the channel base 5 of the control panel 1 on the installation surface 19 of the gantry 16 after the correction of the second insertion hole 20, the first insertion hole 14 and the second insertion hole 20 are integrated with each other. Matches reliably in each operation. As a result, the troublesome work of temporarily removing the control panel 1 from the gantry 16 and correcting the position of the second insertion hole 20 is not required. Therefore, the workability when fixing the control panel 1 on the gantry 16 is remarkably improved, and the installation work of the control panel 1 can be performed efficiently.

  Furthermore, the installation jig 30 of the first embodiment can fold the jig body 31 by removing the holder 36 from the guide rails 32a and 32b so that the guide rails 32a and 32b overlap over the entire length. . For this reason, the installation jig 30 can be easily carried to the work site, and the usability is improved. In addition, there is an advantage that a large storage space is not required when storing the installation jig 30.

(Second Embodiment)
12 and 13 disclose an installation jig 50 according to the second embodiment.

  The second embodiment is different from the first embodiment in the configuration of the jig main body 51 of the installation jig 50. The configuration other than the jig body 51 is basically the same as that of the first embodiment. Therefore, in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 12, the jig main body 51 has three guide rails 52a, 52b, and 52c. The guide rails 52a, 52b, and 52c are formed of straight belt-like plates, and the cross-sectional shape in the direction orthogonal to the longitudinal direction is a trapezoid.

  The guide rails 52a, 52b, and 52c are overlapped with each other in the thickness direction, and a single screw 33 passes through a central portion along the longitudinal direction. Therefore, the guide rails 52a, 52b, and 52c are rotatable between the storage position and the use position around the screw 33. In the retracted position, the guide rails 52a, 52b, 52c overlap over the entire length, and the jig main body 51 becomes a single straight bar. In the use position, the guide rails 52a, 52b, and 52c are developed radially around the screw 33. The crossing angle α of the guide rails 52a, 52b, 52c can be adjusted steplessly by loosening the screw 33. Furthermore, the guide rails 52a, 52b, and 52c can be fixed at any rotational position by tightening the screws 33.

  As shown in FIG. 12, a pair of holders 36 are supported on the guide rails 52a, 52b, and 52c, respectively. The pair of holders 36 supported by the guide rail 52a are distributed to each other in the longitudinal direction of the guide rail 52a with the screw 33 interposed therebetween. The same applies to the holders 36 supported by the other guide rails 52b and 52c. Therefore, the holder 36 on each guide rail 52a, 52b, 52c can slide linearly in a direction approaching or moving away from the screw 33.

  According to the second embodiment, when the guide rails 52a, 52b, and 52c are deployed at the use positions, the distances from the screws 33 to the respective holders 36 are set to be equal to each other. The tips of the protrusions 42 and 43 can be disposed on a common circle C centered on the screw 33.

  Therefore, the installation jig 50 according to the second embodiment corresponds to, for example, the first insertion holes and the first insertion holes arranged at intervals in the circumferential direction on the bottom of a cylindrical tank. It can be used to check whether or not the position of the second insertion hole arranged on the ring-shaped frame is shifted.

  Furthermore, in the second embodiment, for example, by removing the holder 36 from one guide rail 52c, the same usage as the installation jig 30 of the first embodiment is possible.

(Third embodiment)
14 and 15 disclose an installation jig 60 according to the third embodiment.

  The installation jig 60 includes a jig body 61. The jig body 61 is configured by combining straight first to fourth guide rails 62a, 62b, 62c, and 62d in a cross-beam shape.

  Specifically, the first guide rail 62a and the third guide rail 62c are arranged in parallel with a space between each other. The second guide rail 62b and the fourth guide rail 62d are arranged parallel to each other at intervals along the direction orthogonal to the first and third guide rails 62a and 62c.

  As shown in FIG. 14, a portion where the first guide rail 62a and the second guide rail 62b intersect, a portion where the second guide rail 62b and the third guide rail 62c intersect, and a third guide rail The holder 63 is supported at a portion where 62c and the fourth guide rail 62d intersect and a portion where the fourth guide rail 62d and the first guide rail 62a intersect.

  Since the holders 63 have a common configuration, the holder 63 supported by a portion where the fourth guide rail 62d and the first guide rail 62a intersect will be described as a representative.

  As shown in FIG. 15, the holder 63 is configured by a square block. The holder 63 includes a first guide hole 64a through which the first guide rail 62a is slidably penetrated, and a second guide hole 64b through which the fourth guide rail 62d is slidably penetrated. The first guide hole 64 a and the second guide hole 64 b are orthogonal to each other and are separated from each other in the thickness direction of the holder 63.

  The holder 63 has a first surface 65a and a second surface 655b located on the opposite side of the first surface 65a. The first surface 65a and the second surface 65b are flat surfaces parallel to the first guide rail 62a and the fourth guide rail 62d, respectively, and are positioned on both sides along the thickness direction of the holder 63.

  As shown in FIG. 15, the holder 63 has a first screw hole 66 and a second screw hole 67. One end of the first screw hole 66 is opened in the first surface 65 a of the holder 63. The other end of the first screw hole 66 is opened to the first guide hole 64a. One end of the second screw hole 67 is opened in the second surface 65 b of the holder 63. The other end of the second screw hole 67 is opened to the second guide hole 64b.

  A first lock screw 68, which is an example of a lock member, is screwed into the first screw hole 66. The tip 68 a of the first lock screw 68 faces the first guide rail 62 a inside the first screw hole 66. A second lock screw 69, which is an example of a lock member, is screwed into the second screw hole 67. The distal end 69 a of the second lock screw 69 faces the fourth guide rail 62 d inside the second screw hole 67.

  When the first lock screw 68 is tightened, the tip 68a of the first lock screw 68 abuts on the first guide rail 62a, and the holder 63 is fixed to the first guide rail 62a.
