Description

[Detailed Description of the Invention] Technical Field The present invention relates to a wire extending tool used to extend an electric wire through a metal wheel suspended from a steel tower. The present invention relates to a wire drawing tool that connects electric wires and prevents untwisting of electric wires.

BACKGROUND TECHNOLOGY Conventionally, as shown in FIG. The middle part of the bendable connecting yoke 6 that connects the wire 1 and the electric wire 2 is formed so that the front side fits into the groove of the metal wheel 4 and the rear side is formed so that the connecting yoke 3 can be fitted. There was one in which a bendable counterweight 5 for preventing untwisting of electric wires was connected so as to be rotatable in the front and rear direction. However, when extending the line through a metal wheel 4 suspended from an angle steel tower (a steel tower at a position where the direction of the electric line changes), the wire 1 is placed on the metal wheel 4 at an angle within a horizontal plane. As a result, the suspended metal wheel 4 is inevitably tilted as shown in Fig. 2, and as a result, when the wire drawing tool passes the tilted metal wheel 4, it is not affected by its own weight. There was a defect in that the counterweight 5, which was hanging down a lot, collided with the metal wheel 4 and damaged the metal wheel 4, and the counterweight 5 itself was also damaged.

In order to eliminate the above-mentioned defect, as shown in FIG.
A pair of direction correction links 7 formed in a dogleg shape and bendably connected to each other are rotatably articulated, and
A wire drawing tool has been proposed in which a counterweight 5t is suspended from the vicinity of the joint between the connecting yoke 6 and the direction correction link 7 so as to be rotatable in the front and rear directions. However, when the direction correction link 7, which fits into the groove of the metal wheel 4 and moves forward from this state, it pulls the metal wheel 4 forward, and the direction correction link 7 At the same time as it passed the car 4, the metal car 4, which had been pulled forward, returned to the rear.
As a result, the metal wheel 4 and the counterweight 5 collide.Since the hanging distance of the metal wheel 4 corresponding to the moxibustion of the insulator is about 2 to 7 meters, the impact force of the metal wheel 4 due to rotation is extremely large. There was a flaw in that.

In addition, conventionally, as shown in Fig. 4, for the connecting yoke B,
An adapter 8 made of an elastic material such as hard rubber whose lower surface gradually expands toward the rear so as to fit into the groove of the metal wheel 4 is attached to the front side of the connection between the connection yoke 3 and the counterweight 5. A wire drawing tool has been proposed, but this tool cannot fit into the groove of the metal wheel 4 because the tab 8 does not have sufficient bendability. The posture control action for adjusting the counterweight 5 to the position is also insufficient, and in this improperly fitted state, there is a risk that an unnatural force will act locally on the adapter 8, causing damage to the adapter 8. there were.

Furthermore, when using a conventional adapter 8, there is a risk that the connecting yoke 6 and the adapter 8 may rotate relative to each other. 6 moves, the counterweight 5 does not correspond to the groove of the metal wheel 4, and there is a risk that the attitude control effect will be further deteriorated. Moreover, since the adapter 8 must be prepared separately, a wire drawing tool that uses this adapter 8 has to be manufactured.

There was a defect in that the assembly was uneven.

In addition, the wire drawing tool that suspends two counterweights 5 at a distance in order to reliably prevent untwisting of the wires 2 has the disadvantage that the wire drawing tool becomes longer and heavier, making it inconvenient to handle. friend. Furthermore, when the front counterweight 5 passed the metal wheel 4, the same counterweight 5 pulled the metal wheel 4 forward, and as the counterweight 5 passed the metal wheel 4, it moved forward. There was a defect in that the metal wheel 4 returned to the rear, and as a result, the metal wheel 4 and the rear counterweight collided, causing damage to the metal wheel 4 and the counterweight. When two counterweights are suspended, in order to prevent the metal wheel 4 from colliding with the rear counterweight, if the two counterweights are further spaced apart, the wire drawing tool as a whole becomes longer and weighs less. The drawback was that it was heavy and inconvenient to handle, and the cost was high.

The invention was made in order to eliminate the above-mentioned defects, and its purpose was to connect a first attitude control connector located in front of a counterweight that fits into a groove of a connecting yoke and a metal wheel with a plurality of connector elements. In addition to being connected in series so that they can be bent vertically, the lower surface of the connector for controlling the same posture is formed so that it gradually fits into the groove of the metal wheel, and the rear end of the connecting yoke is By connecting a second attitude control connector that is substantially similar to the first attitude control connector in the opposite direction, as the first attitude control connector moves on the metal wheel, the metal wheel is moved. The counterweight fully conforms to the groove of the metal wheel and performs posture control so that it can smoothly pass through the metal wheel without colliding with the metal wheel and counterweight. It is possible to prevent damage to the weight, and it is easier to handle than conventional wire drawing tools, eliminating the need to assemble bulky parts, and furthermore, To provide a wire drawing tool which reliably prevents untwisting and is cheaper than a wire drawing tool in which two counterweights are suspended.

Next, the operation of the embodiment configured as described above will be explained.

Now, as shown in FIG. 5, when the wire drawing tool 62 moves in the direction of arrow P and approaches the wire wheel 17 suspended from the angle steel tower, 12 is placed on the metal wheel 17 at an angle in horizontal pronation, the suspended metal wheel 4 is inclined with respect to the counterweight 26, as shown in FIG. Wire drawing tool 62
moves forward, and the first attitude control connector 11 moves to the metal wheel 1.
7, the first posture control connector 11, which can be bent only in the vertical direction, wraps around the metal wheel 17, and the lower side of the connector 11 gradually fits into the groove of the metal wheel 17. . As a result, the first attitude control connector 1-1 is
While the connector 11 moves to the point tm shown in the figure, the connector 11 gradually moves in the direction of the arrow in FIG. At the same time, the counterweight 26 is also rotated integrally, and the counterweight 23
corresponds to the groove of the metal wheel 17.

When the wire drawing tool 62 moves further forward, No. 10.11
As shown in the figure, the counterweight 26 rides on the groove of the metal wheel 17 while rotating rearward about the pin 19, and the connecting element 15 at the rearmost end of the first attitude control connector 11 moves backward on the metal wheel 17. It fits perfectly into the groove of No. 17. At this time,
Since the bendable counterweight 23 is covered with an elastic body 26 such as rubber, the collision with the metal wheel 17 is alleviated, and the rattling in the left and right direction is reduced, so that it does not fit into the groove of the metal wheel 17. The Vc beam can be raised smoothly. In addition, since the @ side of the counterweight 26 is formed to fit the ura of the metal wheel 17, the connector 11 for the first posture ma
The relative transition of the metal wheel 17 from to the counterweight 26 is performed smoothly.

The connecting yoke 2DK is fitted so as to be continuous with the lower surface of the metal wheel 17 and moves on the metal wheel 17. Even in this state, since the lower surface of the counterweight 26 fits perfectly into the groove of the metal wheel 17, untwisting of the electric wires 61 is prevented.

When the wire drawing tool 62 moves further forward, the metal wheel 17 smoothly moves relatively from the counterweight 26 to the second posture control connector 27, and at the same time the counterweight 26 rotates downward around the pin 19, As shown in FIG. 14, the curved counterweight 26 has an elastic body 26
The restoring force straightens it and suspends it again, but the counterweight 26 twists the wire back! 2nd posture control connector 2 until vertically suspended to prevent ll to the maximum
The lower side surface of the front end of the wire 7 fits snugly into the groove of the metal wheel 17 to reliably prevent the wire 61 from untwisting.

Furthermore, as the second posture control connector 27 moves forward from the position shown in FIG. 14, the connector 27 is gradually rotated in the direction opposite to the arrow direction in FIG. 9, and the counterweight 26 is also rotated. It is rotated gracefully and suspended vertically.

In the embodiment of the present invention, the attitude control connector 11 located in front of the connection yoke 20 and the counterweight 26 is configured by connecting a plurality of connector elements 15 in series so as to be bendable in the vertical direction. The lower surface of the connector 11 is formed to gradually fit into the groove of the metal wheel 17, and the counterweight 26 is formed to be bendable, and the front surface is formed to fit into the groove of the metal wheel 17. Since the entire body is covered with an elastic body 26 such as rubber, as the first attitude control connector 11 passes over the metal wheel 17, it fits well into the groove of the metal wheel 17, and the counter and weight 23
The posture control action is reliably performed so that the metal wheel 17 corresponds to the groove of the metal wheel 17, and as a result, the counterweight 26 passes smoothly over the metal wheel 17, and damage to the metal wheel 17 and the counterweight 23 is prevented.

Further, in the embodiment of the present invention, a second attitude control connector half 27, which is substantially similar to the first attitude control connector 11, is connected to the rear end of the connecting yoke 20 in the opposite direction to the first attitude control connector 11. Even during and immediately after the counterweight 26 passes over the metal wheel 17, untwisting 9 of the electric wire 31 is reliably prevented.

Moreover, since the embodiment of the present invention is configured as described above, the entire wire drawing tool is shorter and the M amount is lighter than the conventional wire drawing tool in which all two counterweights are suspended, making it easier to handle. It is easy and inexpensive.

In addition, in the uninvented embodiment, only one counterweight 26 is suspended, so two counterweights are suspended as in the conventional example.
In the case of full suspension, the defect that the metal wheel collides with the rear counterweight as described above, causing damage to the metal wheel and counterweight, has been completely eliminated.

It should be noted that the invention is not limited to the above-mentioned embodiments. For example, the p1 counterweight 23 with arbitrarily changed number of connector elements 15 configured in the 1.2 posture control connector 11.27 may be integrated. It is also possible to make arbitrary changes, such as forming a different shape, without departing from the spirit of the invention.

Effects As detailed above, the wire drawing tool of the present invention reliably performs bias control so that the counterweight corresponds to the groove of the metal wheel, and as a result, the wire drawing tool can move the metal wheel without collision between the metal wheel and the counterweight. It can pass through smoothly to prevent damage to the wire wheel and counterweight, and it is easier to handle than conventional wire drawing tools, eliminating the need to assemble extra parts. In addition, it is possible to reliably prevent untwisting of electric wires installed with only one counterweight, and compared to wire stretching tools, it is possible to suspend two counterweights.
