  A pad 32 that is pressed against the bucket 101 or the arm metal 151 is attached to the distal end portion of the screw shaft 33, and a handle 36 is attached to the proximal end portion. The screw shaft 33 is screwed into a screw hole 35 provided in the support plate 40, and the handle 32 is rotated to move the pad 32 attached to the tip portion back and forth.

  The pad 32 has a disk shape with a flat front end surface. The pad 32 is fixed to the tip of the screw shaft 33 so as to be rotatable with respect to the screw shaft 33.

  The support plate 40 is made of a rectangular thick member, and is attached to the front surface of the locking body 12 so as to span the pair of left and right U-shaped members 13. The support plate 40 includes a screw hole 35 into which the screw shaft 33 is screwed at the center, and the screw shaft 33 is supported in a state of being screwed into the screw hole 35.

  The length of the support plate 40 is the same as the width of the locking body 12, and the support plate 40 has insertion holes through which mounting bolts 65 for fixing to the front surface of the locking body 12 are inserted on both sides. The insertion hole includes a long hole insertion hole 45 formed in the center portion, and an upper insertion hole 46 and a lower insertion hole 48 formed vertically so as to sandwich the long hole insertion hole 45. The upper insertion hole 46 is provided with a groove 47 communicating with the upper surface 42 of the support plate, and the lower insertion hole 48 is also provided with a groove 49 communicating with the lower surface 43 of the support plate.

  The long hole insertion hole 45 is formed in such a manner that through holes are provided at both ends, and the two through holes are connected to each other. The outer diameter of the through holes and the width of the central part are outside the sleeve 66 of the mounting bolt 65. It is set just slightly larger than the diameter. A length L2 connecting the center points of the through holes provided at both ends of the long hole insertion hole 45 is equal to or longer than the length L5 of the support plate displacement prevention plate 51. As a result, the support plate displacement prevention plate 51 can be attached to the upper or lower portion of the support plate 40 via the attachment bolt 65.

  The outer diameters of the upper insertion hole 46 and the lower insertion hole 48 are the same as the long hole insertion hole 45, and are only slightly larger than the outer diameter of the sleeve 66 of the mounting bolt 65. The widths of the groove 47 connected to the upper insertion hole 46 and the groove 49 connected to the lower insertion hole 48 are the same as the outer diameters of the upper insertion hole 46 and the lower insertion hole 48. The distance L3 from the upper surface 42 of the support plate of the upper insertion hole 46 and the distance L4 from the lower surface 43 of the support plate of the lower insertion hole 48 are the distances of the support plate prevention plate 51 of the locking holes 57 and 58 of the support plate prevention plate 51. It is set equal to the distance L6 from the lower surface 52.

  Each insertion hole is formed such that the interval between the left and right insertion holes matches the interval between the left and right mounting bolts 65 fixed to the locking body 12, and the support plate 40 is interposed via the mounting bolts 65. It is attached to the front surface of the locking body 12.

  As shown in FIG. 9, the support plate may be provided with guide plates 75 and 76 on both sides. The guide plate 50 shown in FIG. 9 is provided with guide plates 75 and 76 at regular intervals on both sides. The distance between the guide plates 75 and 76 is set so that the front leg portion 14 of the U-shaped member is fitted without a gap. Such a guide plate 50 has an effect that the position in the left-right direction is firmly determined and that the pair of left and right U-shaped members 13 are firmly connected.

  The support plate displacement prevention plate 51 is a member for preventing the support plate 40 from shifting in the height direction, and the support plate displacement prevention plate upper surface 56, the support plate upper surface 42, and the support plate via the mounting bolt 65. The upper surface 56 of the slip prevention plate and the lower surface 43 of the support plate are attached to the front surface of the locking body 12 so as to span the pair of left and right U-shaped members 13 so that there is no gap.

  The support plate displacement prevention plate 51 is made of a thick member in which the upper end portions of a rectangular shape are formed in an arc shape. The arc-shaped portions 56 at the upper end portions are formed so that the support plate displacement prevention plate 51 can rotate with the mounting bolt 65 as a starting point in a state where the mounting bolt 65 is fitted in the introduction groove portion 60 (see FIG. 8C). ).

  The length of the support plate displacement prevention plate 51 is the same as the width of the locking body 12, and the thickness of the support plate displacement prevention plate 51 is the same as the thickness of the support plate 40. Since a large load is not applied to the support plate displacement prevention plate 51, it can be formed using plastic.

  A handle 64 is provided at the lower front portion of the support plate displacement prevention plate 51. Furthermore, the support plate prevention plate 51 has locking holes 57 and 58 for locking a mounting bolt 65 for fixing to the front surface of the locking body 12 at the lower part of both sides.

  The locking hole 57 includes a hole 59 having the same size as the outer diameter of the sleeve 66 attached to the mounting bolt 65 and an L-shaped introduction groove 60 communicating with the hole 59. The width of the introduction groove 60 is slightly larger than the outer diameter of the sleeve 66, and the end faces the lower surface 52 of the support plate prevention plate 51. The introduction groove 60 is formed so that the mounting bolt 65 can be smoothly guided to the hole 59. The lateral length of the introduction groove portion 60 is set longer than the introduction groove portion 61 of the locking hole 58. When the support plate displacement prevention plate 51 is fully moved to the right side, the left end of the support plate displacement prevention plate 51 is It comes off from the mounting bolt 65 (see FIG. 8B).

  A small protrusion 62 is provided at the boundary between the introduction groove 60 and the hole 59 and is slightly narrowed. When the support plate displacement prevention plate 51 is pushed in by applying a little force to the attachment bolt 65 so as to get over the protrusion 62, the support plate displacement prevention plate 51 is firmly locked to the attachment bolt 65.

  The locking hole 58 includes a hole 59 having the same size as the outer diameter of the sleeve 66 attached to the attachment bolt 65 and a linear introduction groove 61 communicating with the hole 59. The width of the introduction groove 61 is slightly larger than the outer diameter of the sleeve 66, and the end faces the side surface 53 of the support plate prevention plate. A small protrusion 63 is provided at the boundary between the introduction groove 61 and the hole 59 and is slightly narrowed. When the support plate displacement prevention plate 51 is pushed in by applying a little force to the attachment bolt 65 so as to get over the protrusion 63, the support plate displacement prevention plate 51 is firmly locked to the attachment bolt 65.

  The mounting bolt 65 is for fixing the support plate 40 and the support plate displacement prevention plate 51 to the front surface of the locking body 12, and includes a sleeve 66, a bolt 67, a washer 70, and a nut 71. Three are installed on the left and right sides of the front surface of 12, respectively, for a total of six.

  The sleeve 66 is a thin metal cylinder that is only slightly longer than the thickness of the support plate 40 and the support plate displacement prevention plate 51. The position of the bolt head 68 is determined by the length of the sleeve 66. For this reason, there is only a slight gap between the bottom of the bolt head 68 and the front surface 41 of the support plate and the front surface 54 of the support plate displacement prevention plate.

  The bolt 67 is a hexagon socket head bolt with a flange, inserted into the sleeve 66, inserted into the through hole 20 provided in the front leg portion 14 of the U-shaped member, and screwed into the nut 71 embedded in the recess 21. To do. When the bolt 67 and the nut 71 are screwed together, the bolt 67 and the nut 71 are attracted to each other, the end portion of the sleeve 66 is locked to the front surface of the front leg portion 14 of the U-shaped member, and the washer 70 is Locked to the wall and fixed.

  The mounting bolts 65 on the front surface of the locking body 12 are mounted at the same height on the left and right, and the three mounting bolts 65 on one side are mounted at equal intervals. The mounting bolt 65 in the middle of the mounting bolts 65 is fitted into the long hole insertion hole 45 of the support plate, and either the upper insertion hole 46 or the lower insertion hole 48, the locking hole 57 of the support plate displacement prevention plate, The upper and lower mounting bolts 65 are attached to 58.

  As described above, there is only a slight gap between the bottom of the bolt head 68 and the front surface 41 of the support plate and the front surface 54 of the support plate slip prevention plate. Furthermore, since there is a slight gap between the sleeve 66 and the long hole insertion hole 45, the upper insertion hole 46, and the lower insertion hole 48, the mounting plate 65 is attached to the support plate 40 only after the gap. Can move.

  On the other hand, the support plate displacement prevention plate 51 cannot move up and down after the mounting bolts 65 are attached because the locking holes 57 and 58 and the sleeve 66 have the same outer diameter. After the support plate displacement prevention plate 51 is attached, the support plate 40 and the support plate displacement prevention plate 51 are in contact with each other without a gap, so that the support plate 40 cannot move in the vertical direction.

  As described above, the mounting bolt 65 restricts the movement of the support plate 40 and the support plate displacement prevention plate 51 in the vertical and horizontal directions and the front and rear directions without completely fixing the locking body 12. Therefore, the support plate displacement prevention plate 51 can be attached to and detached from the locking body 12 with the attachment bolts 65 attached. If the support plate displacement prevention plate 51 is removed, the support bolts 65 are attached and supported. The plate 40 can be slid up and down.

  A method of using the insulating rod support 1 will be described. When attaching the insulating rod support 1 to the bucket 101 of an aerial work vehicle, the support plate shift prevention plate 51 is set upward and the support plate 40 is set downward as shown in FIGS. As a result, the position of the pad 32 is lowered, and the pad 32 can be pressed against the peripheral wall surface 103 which is not the flange portion 102 of the bucket. This method of use is the same as the conventional insulating rod support 201.

  When the insulating rod support 1 is attached to the brace 151, the support plate displacement prevention plate 51 is set downward and the support plate 40 is set upward as shown in FIGS. As a result, the position of the pad 32 is raised, and the pad 32 can be firmly pressed against the arm metal 151 and is firmly fixed.

  A procedure for changing the position of the support plate 40 will be described with reference to FIG. From the state in which the support plate displacement prevention plate 51 is set downward and the support plate 40 is set upward (FIG. 8A), the support plate displacement prevention plate 51 is changed upward (FIG. 8F). )) Is an example.

  The support plate displacement prevention plate 51 is moved fully to the right side (FIG. 8B). Since the support plate displacement prevention plate 51 is not completely fixed by the mounting bolt 65 as described above, the support plate displacement prevention plate 51 can be moved to the right without removing the attachment bolt 65.

  When the support plate displacement prevention plate 51 is moved fully to the right, the left end 53 of the support plate displacement prevention plate 51 is detached from the mounting bolt 65. In this state, the left end 53 of the support plate displacement prevention plate 51 is lowered downward, and the support plate displacement prevention plate 51 is rotated by rotating the support plate displacement prevention plate 51 from the right mounting bolt 65 (FIG. 8C). It can be removed (FIG. 8D).

  When the support plate 40 is pushed downward with the support plate displacement prevention plate 51 removed, it is easily lowered. This is because, like the support plate displacement prevention plate 51, the mounting bolt head 68 is not in contact with the front surface 41 of the support plate 40, and the support plate 40 is not completely fixed by the mounting bolt 65.

  After the support plate 40 is fully lowered (FIG. 8 (E)), the support plate displacement prevention plate 51 may be attached above the support plate 40 (FIG. 8 (F)). The attachment procedure of the support plate displacement prevention plate 51 may be performed in the reverse order of the removal.

  Since the insulating rod support 1 composed of the above can be used in a place other than the bucket 101 of an aerial work vehicle, it is restricted to the movement of the bucket 101 by using it attached to the armrest 151 mounted. Disappears. Since it can be used even when working at a place where an aerial work vehicle cannot be used, labor for gripping an electric wire or the like by a pole worker is also reduced. Moreover, by attaching a temporary arm metal to the utility pole, the work range on the pole is increased, and the operator's fatigue is reduced.

  As described above, since the insulating rod support 1 can change the position of the pad according to the form of the attached tool, it can be firmly fixed to the attached tool. In addition, the pad position can be changed easily and reliably by changing the arrangement of the support plate that supports the pad so that it can move forward and backward and the support plate displacement prevention plate that prevents the pad from shifting. it can. Further, when the arrangement of the support plate and the support plate displacement prevention plate is changed, the change can be made without removing the mounting screw, so that the workability is excellent and the usability is very good.

  The present invention is not limited to the above-described embodiment, and can be changed and used without changing the gist. Moreover, in the said embodiment, although the insulation rod support tool 1 which can be attached to the bucket 101 of an aerial work vehicle and the arm bracket 151 mounted on the utility pole was shown, a to-be-attached tool is limited to a bucket and an arm bracket. It is not a thing, but can be used by attaching to machines, instruments, tools, etc. The tool fixture according to the present invention is not limited to the insulating rod support, and may be another tool fixture.
