Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a gold wheel used for crossing an overhead line such as a communication cable.

<Prior Art> In order to lay communication cables and the like in the air, as shown in FIG. 6 (A), utility poles 1 are constructed at predetermined intervals, and fixing brackets 2 are provided on the upper side surfaces of them. Cable 3
The method of fixing is common.

Therefore, in the past, as shown in FIG. 6 (B), the tip of the cable 3 or the rope (towline) 4 connected to it is
Etc. are inserted into a pulley 5 (corresponding to a gold wheel according to the present invention) temporarily fixed to a utility pole 1 by a worker using a crotch tool 6 which is inserted from the ground, and after extending over a plurality of utility poles 1, Finally the sixth
It was fixed by the fixing metal fitting 2 shown in FIG.

Further, as shown in FIG. 7, the pulley 5 has a support arm 8 for rotatably supporting the wheel 7 formed in a bifurcated closed type to prevent the cable 3 from falling off. The support arm 8 is further divided into left and right parts and joined by screws 9 so that the cable 3 can be taken out when necessary. Reference numeral 10 in FIG. 7 denotes a hook-shaped portion attached to one half of the support arm 8, and the pulley 5 is temporarily fixed to the electric pole 1 via the hook-shaped portion 10.

<Problems to be solved by the invention> By the way, recently, a series of work such as the installation of the fixing metal fitting 2 and the fixing of the cable 3 to the fixing metal fitting 2 has been conventionally performed by manual work at a dangerous height. However, there is a strong demand for remote control on the ground, and various measures have been taken, but the conventional pulley 5 has the following problems.

(1) Since there is only one wheel 7, the position of the cable 3 mounted on it is not fixed and remote operation is difficult.

(2) Since there is only one hook-shaped portion 10, the entire pulley 5 swings and the position of the cable 3 cannot be determined, making remote operation difficult.

(3) When taking out the cable 3 from the closed type support arm 8, the screw 9 must be removed to open the support arm 8, which is not suitable for remote operation.

(4) If the temporary fixing bolt of the hook-shaped portion 10 and the mounting bolt of the fixing metal fitting 2 are used in common, the pulley 5 becomes an obstacle and it is difficult to fix the cable 3 to the fixing metal fitting 2 and remote control is difficult.

Therefore, an object of the present invention is to provide an optimal gold wheel to remotely control the crossing work.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention is a gold wheel used when temporarily placing it on an upper portion of a support of an overhead track, and can be temporarily fixed to the upper portion of the support. The supporting member has leg rods attached to both ends of the base rod, and a wheel pivotably supported on the same side face of the ends of the leg rods to support an overhead line along the base rod. It is characterized in that a recess is formed on the side of the rod opposite to the wheel for transferring the overhead line from both wheels to the upper side of the support.

<Operation> According to the configuration described above, the position of the overhead line is determined by the two wheels, while the recesses in both leg plates facilitate the transfer of the overhead line by remote control from the ground.

<Embodiment> An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a gold wheel 20 according to the present invention includes a support member 21 and two wheels 22, 23 supported by the support member 21.
Consists of

The support member 21 hangs leg rods 24 and 24 from both front and rear ends of a base rod 23 that can be temporarily fixed to the upper portion of a telephone pole 1 (see FIGS. 6 (A) and (B)) as a support. A recess 25 protruding leftward in a U-shape is formed at an intermediate portion in the vertical direction of the two leg rods 24, 24.

On the other hand, each of the wheels 22 and 22 is pivotally supported on the right side surface of the lower end of each of the leg rods 24 and 24 so as to support the cable 3 as an aerial line along the base rod 23. is there.

And the above-mentioned recess 25 connects the cable 3 to both wheels 22,2.
2 It is large enough to be transferred from the top to the upper side of the utility pole 1 which will be described later. Further, in the illustrated example, two fixing holes 26 for temporarily fixing to the upper side of the electric pole 1 are provided in the front-rear intermediate portion of the base rod portion 23.

It should be noted that the cable 3 is provided with an elongated cut 27 at the connecting portion between the large-diameter main wire 3a and the small-diameter support wire 3b by another cutting tool.
Are formed in the longitudinal direction. In addition, this cable 3 uses the manipulator arm 6A from the ground to both wheels of the gold wheel 20.
It is installed on 22,22.

Next, the procedure of the intermediary work using the gold wheel 20 according to the present invention will be described with reference to FIGS.

First, an L-shaped fixing metal fitting 2A for fixing the cable 3 is attached to the upper part of the electric pole 1 in advance. As shown in FIG. 3, the fixing metal fitting 2A is divided into half and screwed.
It is fastened with a nut 33 to a mounting bolt 32 of a metal fitting mounting band 31 joined by 30. The metal fitting band 31 and the fixing metal fitting 2A are attached to the telephone pole 1 by an intermediary work robot or the like (not shown) that is remotely operated from the ground.

Next, the gold wheel 20 is temporarily fixed to the mounting bolt 32. That is, after the fixing hole 26 of the base rod portion 23 is fitted into the mounting bolt 32, the nut 34 is used to prevent it from coming off. This work is also performed by the above-mentioned crossover work robot.

After this, as shown in FIG. 2 (A), connect the cable 3 to the gold wheel 20.
It is temporarily placed on the wheel 22 of the vehicle by operating the manipulator arm 6A from the ground and extends over a plurality of utility poles 1.

Next, as shown in FIG. 2 (B), after the cable 3 is floated above the wheel 22 by operating the crotch tool 6 from the ground,
Using the recess 25, as shown in FIG. 2 (C), the cable 3
Hook the support wire 3b of the above to the fixing metal fitting 2A to fix it. That is,
The fixing metal fitting 2A is inserted into the notch 27 of the cable 3.

In this way, in the present embodiment, the cable 3 can be quickly and smoothly transferred from above the wheels 22 and 22 to the fixing metal fitting 2A using the recess 25 as a working space. The recess 25 is not U-shaped as in the illustrated example, but the leg rod 24 may be simply curved.

Next, FIGS. 4 and 5 show another embodiment of the present invention.

FIG. 4 shows an L-shaped stopper plate 3 on the right side edge of the lower ends of both leg rods 24, 24.
5, 35 are attached, and FIG. 5 shows an example in which the cable guide groove 22a of the wheel 22 is formed deeper than the diameter of the cable 3 to prevent the cable 3 from falling off.

<Effects of the Invention> As described above, according to the present invention, it is possible to avoid the work of people at a high place, and to safely and efficiently operate an overhead line such as a communication cable from the ground by remotely controlling the upper part of a support such as a utility pole. Can be laid on.
