Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a hanging wheel for angle use, and relates to a hanging wheel used for cable bends in cable extension work for power or communication cables. .

[Conventional technology and its problems]

In the part where the cable curves in the horizontal plane, the angle suspension wheel used conventionally has multiple rollers installed between two opposing frames, and the bridge part that connects the upper parts of the frames is connected to the suspension wheel arm. It was designed to be hung from the ceiling.

When a cable is passed over the rollers of the above-mentioned hanging wheel and the wire is extended while being bent in a horizontal plane, the hanging wheel is pulled toward the center of the curve and tilted, and the cable comes off the rollers. , there is a problem with contacting the inside of the frame.

Furthermore, when attempting to handle cables with a large radius of curvature, the frame itself becomes large in conventional cables, which increases the overall weight and makes it difficult to handle.

The purpose of this invention is to provide an angle suspension wheel that solves these problems.

[Means for solving problems]

In order to solve the above problems, this invention forms a metal wheel mounting bracket with a strip plate curved with a required radius of curvature, and attaches three or more metal wheels with rolls attached to an inverted U-shaped frame. at the required intervals,
The frame of the metal wheel attached to both ends of the metal wheel mounting bracket is provided with a hook projecting to the outside of the curve, and the metal wheel is attached to the metal wheel mounting bracket. It has a structure in which two hanging wire attachment fittings are attached to the metal fitting so as to protrude to the outside of the curve.

[Effect]

The above-mentioned angle suspension wheel is suitable for extending cables by bending them along the corners of orthogonal suspension wires.
Alternatively, it is used to extend the wire in a curved manner along the inside or outside of the pole using a metal wheel arm fixed to the pole. In the former case, hooks provided on the metal wheels at both ends and two hanging wire attachment fittings are engaged with and attached to the hanging wire. In the latter case, a metal wheel mounting bracket is attached to a metal wheel arm fixed to a utility pole.

In either case, the cable is guided by the rollers of each metal wheel, and is extended while curving in a horizontal plane according to the curvature of the metal wheel mounting bracket.

〔Example〕

FIG. 1 shows an angle suspension wheel according to an embodiment of this invention. This hanging wheel includes a metal wheel mounting bracket 1 made of a curved strip having a required radius of curvature,
It consists of four metal wheels 2 and two hanging wire attachment fittings 3.

As shown in FIG. 2, each metal wheel 2 has a roller 5 attached to an inverted U-shaped frame 4, and the frame 4 has a frame piece 7 supporting one end of a roller shaft 6 and a frame piece 7 supporting the other end. It is divided into supporting frame pieces 7' and integrally connected by butterfly bolts 8 and nuts 9, and a hook 10 is provided at the upper end of one frame piece 7.

Each of the above-mentioned metal wheels 2 has a frame piece 7,
Sandwich both sides of the metal wheel mounting bracket 1 with the ends of 7',
The roller 5 is positioned inside the curve and fixed by a wing bolt 8 and a nut 9.

The hanging wire attachment fitting 3 is made by stacking two upper and lower metal pieces 10', as shown in FIG.
Each metal piece 10' is bent in the middle so that a certain gap is created between the two, and a hanging wire clamping piece 11 is provided on the opposing surface of the tip of the metal piece 10'.
0' and 10' are fixed by butterfly bolts and nuts 12.

The above-mentioned hanging wire attachment fitting 3 is attached by bolts and nuts 13 close to the two metal wheels 2 attached to the center portion of the metal wheel attachment fitting 1.

Further, the metal wheel mounting bracket 1 has a mounting hole 14 formed between the metal wheels 2.

The angle hanging wheel of this invention has the above structure, and its operation will be explained next.

When installing this hanging wheel on the utility pole 15, the fourth
A metal wheel arm 16 as shown in the figures and FIG. 5 is used. This metal wheel arm 16 includes a mounting hardware 17 that is fixed around the utility pole 15, an arm 18 that is integrated with the mounting hardware 17, and a support hardware 1 that is fixed to the arm 18.
9. It consists of two stays 20, 20 attached to both ends of the support fitting 19.

As shown in Figure 4, the cable 2 is placed inside the utility pole 15.
1, when extending the line, place the telephone pole 15 so that it is located outside the curve of the metal wheel mounting bracket 1,
The metal wheel mounting bracket 1 is attached to the lower surfaces of the tips of the two stays 20 and the lower surface of the center of the arm 18 via spacers 22 and 23, respectively, using the aforementioned mounting hole 14. In this case, since the hanging wire attachment fitting 3 is not used, it is folded along the metal wheel attachment fitting 1.

In addition, as shown in FIG. 5, when extending the cable 21 to the outside of the utility pole 15, place the utility pole 15 so that it is located inside the curve of the metal wheel mounting bracket 1.
The bottom surface of the tips of the two stays 20, 20 and the arm 1
Attach to the bottom surface of the tip of 8.

In addition, as shown in Fig. 6, when attaching to the corners of the cross-shaped suspension wire 24, the metal wheels 24 at both ends
The hooks 10 are engaged with the hanging wires 24, respectively, and the hanging wire attachment fittings 3 are fixed to the hanging wires 24, thereby attaching the wires.

Cable 21 is attached to the hanging wire fittings installed as described above.
To insert it, insert it from the metal wheel 2 at one end to the metal wheel 2 at the other end in order.

〔effect〕

As mentioned above, in this invention, three or more metal wheels are attached to the metal wheel mounting bracket made of a curved strip, so even in the case of a curved road with a large radius of curvature, the entire hanging wheel can be weight can be reduced.

Moreover, since each metal wheel is attached so as to protrude inside the curve of the metal wheel mounting bracket, the tension of the cable is applied to the bottom of the groove of the roller of each metal wheel. Therefore, the cable will not come off the roller.

Furthermore, by attaching the metal wheel arm to a utility pole, it can be used for either an inner or outer loop, and when attached to a cross-suspension line, it can be directly attached using only the hanging bracket of this invention without using any other means. I can do it.
