Description

  The present invention is detachably attached to a spacer that holds a distance between a pair of overhead wires installed in parallel, and allows a suspension device moving along the pair of overhead wires to pass over the spacer and pass. The present invention relates to an airborne passage guide and an airborne passage guide assembly.

  Maintenance and inspection of transmission lines, re-working, etc. may be carried out by suspending an air hoist from a pair of overhead wires that are stretched in parallel between steel towers and moving the air hoist along the wires. is there. A pair of overhead wires that suspend such a hoister is provided with a spacer to prevent contact between the overhead wires due to vibration or the like, and one end of the pair of overhead wires is gripped at one end of the spacer. The other of the pair of overhead wires is gripped on the other end side so that the distance between the two overhead wires is maintained. However, since the spacer installed between the pair of overhead wires becomes an obstacle to the wheels of the scorpioner that moves along the pair of overhead wires, it enables the wheels of the scorpioner to get over and move. An airborne passage guide has been devised.

  FIG. 13 shows a conventionally known astronaut passage guide (spacer passage spacer filler) 100. 13 is attached to a position adjacent to the spacer 101 on the overhead electric wire 103 on the front side (before passing through the spacer 101) in the movement direction of the wheel 102 of the suspender relative to the spacer 101. The hoist wheel 102 is formed in a truncated cone shape that can lift the overhead wire 103 from the overhead electric wire 103 to the upper surface position of the spacer 101. In addition, the air hoist passage guide 100 forms a wire receiving hole 105 for receiving the overhead wire 103 by connecting the half piece 100a and the half piece 100b with a hinge 104, and the spacer 101 is attached to the spacer 101 with a fastening tool (not shown). It is attached to the overhead electric wire 103 at an adjacent position (see Patent Document 1).

Japanese Utility Model Publication No. 58-179821

  However, since the conventional pedestrian passage guide tool 100 shown in FIG. 13 is formed of metal or hard plastic, it rubs against the overhead wire 103 when it is attached to or detached from the overhead wire 103, and the wheel 102 of the suspender 102 There is a possibility that the overhead electric wire 103 is rubbed by receiving a load or an impact acting when passing, and the overhead electric wire 103 may be damaged. In addition, since the conventional hoistor passing guide 100 shown in FIG. 13 is attached only to the overhead electric wire 103 before passing through the spacer, the wheel 102 after passing through the spacer is attached to the overhead electric wire 103 from the upper surface of the spacer 101. It falls down and an impact load acts on the overhead electric wire 103, and the overhead electric wire 103 is easily damaged. In such a case, it is conceivable to attach the airborne passage guide 100 to the overhead electric wire 103 before passing through the spacer and to the overhead electric wire 103 after passing through the spacer. This deteriorates the work efficiency of maintenance / inspection of the overhead electric wire 103.

  Therefore, the present invention provides a guide for passing through an air hoist that does not cause damage to the overhead electric wire during attachment / detachment to / from the overhead electric wire and passes through the wheel of the air hoist, and that does not deteriorate the work efficiency of maintenance / inspection of the overhead electric wire. Provided are a tool and a suitcase passing tool assembly.

The present invention relates to a hoist 4 that is detachably attached from above to a spacer 3 that keeps a distance between a pair of overhead wires 2 and 2 installed in parallel, and moves along the pair of overhead wires 2 and 2. The present invention relates to a pedestrian passage guide 1 that allows a wheel 5 to pass over a spacer 3.
The present embodiment of the present embodiment of the present invention is shown in FIG.
A first wheel guide portion 12 for gradually increasing the height position of the wheel 5 from the overhead wire 2 as the wheel 5 approaches the spacer 3, and guiding the wheel 5 along the overhead wire 2;
A second wheel guide portion 14 for gradually reducing the height position of the wheel 5 from the overhead wire 2 as the wheel 5 moves away from the spacer 3, and guiding the wheel 5 along the overhead wire 2;
Located between the first wheel guide portion 12 and the second wheel guide portion 14, the wheel 5 is smoothly moved along the overhead wire 2 from the first wheel guide portion 12 to the second wheel guide portion 14. And an intermediate wheel guide portion 13 that enables the wheel 5 to get over the spacer 3 along the overhead electric wire 2.
In the present embodiment, the first wheel guide part 12, the intermediate wheel guide part 13, and the second wheel guide part 14 are integrally formed of rubber.

  Since the present embodiment of the present invention is made of rubber and can be easily deformed by the action and impact of external force, it is a conventional metal or hard plastic suspender. Compared to the passage guide, even if the overhead wire is rubbed with the spacer during attachment / detachment to the spacer or when an impact or vibration is applied, the overhead wire is not damaged.

  In addition, in the present embodiment, the first wheel guide portion, the intermediate wheel guide portion, and the second wheel guide portion are integrally formed, and the front and rear of the spacer can be obtained by a single mounting operation to the spacer. As a result, it is possible to smoothly move over the spacer along the overhead wire. Installation work can be reduced and work efficiency such as maintenance and inspection of overhead wires can be improved.

(Aircraft Passing Guide)
FIG. 1 is a perspective view showing a usage state of a hoistor pass guide 1 according to an embodiment of the present invention. As shown in FIG. 1, a pair of overhead wires 2 and 2 are installed in parallel between steel towers (not shown), and spacers 3 are attached at predetermined intervals along the direction in which the overhead wires 2 extend. The distance between the two overhead wires 2 and 2 is maintained by 3. On the pair of overhead wires 2, 2, a hoist 4 on which an operator rides is suspended so as to move along the overhead wires 2, 2. The air hoist 4 has four wheels 5 that rotate and move on the overhead electric wires 2 and 2 positioned at the upper part, two are arranged on one and the other of the pair of the overhead electric wires 2 and 2, respectively. One of the overhead wires 2 and 2 and the other wheels 5 and 5 are connected by an axle 6 extending in a direction perpendicular to the overhead wires 2 and 2. The wheel 5 is formed with a concave groove 7 having an arc-shaped cross section along the outer periphery so that the wheel 5 can engage with the overhead electric wire 2 having a circular cross section (see FIG. 3). The concave groove 7 of the wheel 5 has a radius of curvature larger than the radius of the overhead wire 2 and is in contact with the outer peripheral surface of the overhead wire 2 with an arc.

  As shown in FIGS. 1 to 3, the spacer 3 includes a pair of wire gripping portions 8 and 8 that grip one and the other of the pair of overhead wires 2 and 2, and a connecting rod that connects the wire gripping portions 8 and 8. 10. The electric wire gripping portion 8 has a substantially rectangular parallelepiped shape, and has a wire insertion hole 11 through which the overhead electric wire 2 passes. Then, the spacer 3 is detachably attached to the spacer 3.

  As shown in FIGS. 1 to 4, the hoistor passing guide 1 is detachably attached to the spacer 3 (the electric wire gripping portion 8) from above and moves along the pair of overhead electric wires 2 and 2. The wheel 5 of the vessel 4 can pass over the spacer 3 (the electric wire gripping portion 8). The air hoist passage guide 1 includes a first wheel guide unit 12, an intermediate wheel guide unit 13, and a second wheel guide unit 14. Among these, the 1st wheel guide part 12 increases the height position of the wheel 5 from the overhead wire 2 gradually as the wheel 5 which moves on the overhead wire 2 approaches the spacer 3, and makes the wheel 5 along the overhead wire 2 along. It comes to guide you. In addition, the second wheel guide unit 14 gradually decreases the height position of the wheel 5 from the overhead wire 2 as the wheel 5 moves away from the spacer 3, and guides the wheel 5 along the overhead wire 2. . The intermediate wheel guide portion 13 is located between the first wheel guide portion 12 and the second wheel guide portion 14, and the shape of the upper surface 15 along the overhead electric wire 2 is formed in an upwardly convex arc shape. Is smoothly guided along the overhead electric wire 2 from the first wheel guide portion 12 to the second wheel guide portion 14, thereby enabling the wheel 5 to get over the spacer 3 while drawing an upward convex arc. And these 1st wheel guide parts 12, the intermediate wheel guide part 13, and the 2nd wheel guide part 14 are integrally formed with rubber | gum.

  Moreover, as shown in FIG.3 and FIG.4, when the 1st wheel guide part 12, the intermediate | middle wheel guide part 13, and the 2nd wheel guide part 14 cut | disconnect on the virtual plane orthogonal to the overhead electric wire 2, The shape of the upper surface 15 facing the outer peripheral surface (the peripheral surface of the groove 7) is an upwardly convex arc shape (see, in particular, FIG. 3, FIG. 4 (e), FIG. 4 (f)), and the outer peripheral surface of the wheel 5 The arcuate grooves 7 are engaged with the concave and convex portions. As shown in FIG. 3, the curvature radius of the upper surface 15 of the first wheel guide portion 12, the intermediate wheel guide portion 13, and the second wheel guide portion 14 is larger than the curvature radius of the concave groove 7 on the outer peripheral surface of the wheel 5. Is also getting smaller.

  Further, as shown in FIGS. 1 to 4, the hoistor pass guide 1 has a spacer engaging recess 16 and a wire engaging recess 17. The spacer engaging recess 16 is configured such that when the airborne passage guide 1 is engaged with the spacer 3 (the electric wire gripping portion 8) from above, the direction along the overhead electric wire 2 is set. And the rotation of the airborne passage guide 1 with respect to the overhead wire 2 is stopped. The spacer engaging recess 16 includes an upper wall surface 18 that is placed on the spacer 3 (the electric wire gripping portion 8), and a pair of side walls 20 that are positioned so as to cross the overhead electric wire 2 and sandwich the spacer 3 (the electric wire gripping portion 8). A recess formed by 20 and so on. As shown in FIG. 4, the spacer engaging recess 16 has a shape in which the lower surface side is cut out in a square shape along the Y-axis direction (width direction). In addition, the wire engaging recess 17 is located on both sides along the overhead wire 2 with respect to the spacer engaging recess 16 and opens downward, and the spacer engaging recess 16 is formed in the spacer 3 (wire gripping portion 8). When being engaged from above, the overhead wire 2 is engaged from above. Further, as shown in FIGS. 3, 4 (e), and 4 (f), the electric wire engaging recess 17 is formed in an inverted U-shaped cross section so that the overhead electric wire 2 can be accommodated in the internal space. It is like that.

  As shown in FIG. 1 to FIG. 3, the hoistor passing guide 1 according to the present embodiment having the above-described configuration is attached to the spacer 3 (the electric wire gripping portion 8). By smoothly moving the wheel 5 along the upper surface 15 of the first wheel guide unit 12, the intermediate wheel guide unit 13, and the second wheel guide unit 14, the wheel 5 of the hoist 4 is aerial in front of the spacer 3. It is possible to move smoothly from the electric wire 2 to the overhead electric wire 2 behind the spacer 3 over the spacer 3 (electric wire gripping portion 8). And since this air hoist passage guide 1 is entirely formed of rubber, when guiding the movement of the wheel 5 of the air hoist 4, between the wheel 5 and the overhead electric wire 2 and the wheel 5 And the spacer 3 (electric wire gripping portion 8), and the impact and vibration transmitted through the wheel 5 can be flexibly deformed and absorbed.

  Further, the present embodiment of the present embodiment of the present embodiment of the present embodiment of the present invention is based on rubber, and can be easily deformed by the action of external force or impact. Compared to the present embodiment, the overhead electric wire 2 may be damaged even if it is rubbed with the overhead electric wire 2 at the time of attachment / detachment to the spacer 3 (electric wire gripping portion 8), impact or vibration.

  In addition, in the air hoist passage guide 1 according to the present embodiment, the first wheel guide portion 12, the intermediate wheel guide portion 13, and the second wheel guide portion 14 are integrally formed, and the spacer 3 (the electric wire gripping portion 8). The overhead wire 2 before and after the spacer 3 is covered by one mounting operation to the spacer 3 so that the wheel 5 of the hoist 4 can smoothly get over the spacer 3 (wire gripping portion 8) along the overhead wire 2. Therefore, compared with the conventional airborne passage guide 100, the number of man-hours for installing the airborne passage guide 1 can be reduced, and maintenance / inspection work of the overhead wire 2 using the airborne 4 can be reduced. Efficiency can be improved.

  In addition, since the air hoist passage guide 1 according to the present embodiment is entirely made of rubber, it is made of metal compared to the conventional metal or hard plastic air hoist passage guide 100. The wheel 5 is difficult to slip, and the wheel 5 can easily and reliably move over the spacer 3 (the electric wire gripping portion 8). As a result, the hoistor passing guide 1 according to the present embodiment reduces the burden on the operator who performs the maintenance / inspection of the overhead electric wire 2 on the hoistor 4 and improves work efficiency. Can do.

  In addition, since the hoistor passing guide 1 according to the present embodiment is entirely made of rubber, it can be flexibly deformed with respect to the overhead electric wires 2 having different sizes, and the overhead electric wires are placed in the electric wire engaging recesses 17. 2 can be accommodated. On the other hand, since the conventional air hoist passage guide 100 is made of metal or hard plastic, it must be prepared for each overhead electric wire 103 having a different size, which increases costs and provides a large storage space. Needed.

  In addition, since the air hoist passage guide 1 according to the present embodiment is entirely formed of rubber, even if it is dropped during attachment work to the spacer 3 (electric wire gripping portion 8) or the like, the lower level overhead electric wire 2 is less likely to be damaged, and the operator located below is less likely to be damaged. On the other hand, since the conventional air hoist passage guide 100 is entirely made of metal or hard plastic, there is a risk of damaging the lower overhead wire 103 if dropped during attachment to the spacer 101 or the like. Moreover, there is a risk of damaging a worker located below.
