Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a self-propelled electric wire (1) in which a come-along overhead electric line (1) is pushed and transferred by a self-propelled (1t) positioned at the rear in the advancing direction (1f). Regarding the ceremony come-along.

(Prior Art) FIG. 3 shows a partially sectional side view of an example of a conventional come-along. In the drawings, (2+) is an n-shaped come-along main body, and the inner surface (22) is partially tapered. (23) is a wedge; wedge (23)
has a two-part structure and is inserted into the inner surface of the come-along body (2), and as the insertion deepens, the wire gripping hole formed at the intersection of the wedges (23) shrinks and tightens the wire. . (24) is a pin, and the end of the cam mechanism (26) formed at the - end of the handle (25) in the protruding part (21') from the main body (21) is attached to the wedge (23). The handle (25) and the main body (21) are arranged so as to face the head end of the handle (25) and the main body (21).
are connected. The navigation mechanism (26) is the handle (25)
It is split into two forks at the tip, and the electric wire is configured to pass between them.

Therefore, the come-along main body (21) described in 1- is configured to be able to be opened and closed in a hinged manner, and when the main body (21) is opened,
By fitting the wire into the wire holding hole of the wedge (23) and closing the main body (21), the main body (21) is held by the wire and can slide over the wire. Here, attach II to one end of the handle (25).
When the attached tension wire is pulled with a winch or the like, the handle (25) rotates around the connecting pin (24'), and the end of the cam mechanism (26) formed at the end of the handle rotates. Push the end of the Ua part of (23) toward I with the electric wire in between 11
Push the tip (23) into the inner surface of the main body (2I), and
3) holds the wire stably.

(Problem to be solved) Although the wire is grasped by come-along at a position as far away as the steel tower, it is not possible to manually slide the wire along the wire to the (+'+) position. This is a dangerous job.Furthermore, the come-along is quite heavy, so there is a lot of friction between the wire and the wedge, and it requires a lot of effort.

Because of this, the electric wire is behind the direction of travel of the come-along.
- Position the self-propelled vehicle running at 1-, and use the self-propelled vehicle to back up the come-along, transport it to a predetermined position, and stop 1-
A method is being considered in which only self-propelled vehicles are collected and cordoned off.

However, as mentioned above, the come-along has ll'l/
Attach the tension wire attached to the attached handle to the ground 1. The tension line work is carried out using a winch or the like, but the dead weight of the tension wire and the tension semi-metal wheel through which the wire passes is applied to the come-along.

When the weight of the tension wire and semi-metal wheel is added to the come-along, the friction between the wedge of the come-along and the wire increases, and as a result, the pushing force of the self-propelled vehicle increases,
There is also the problem of damaging the electric wires.

(Means for solving problem +:, j) The present invention solves the problem described in 1-1,
This product provides a self-propelled come-along configured to leave its own weight on a self-propelled vehicle, and its features include a force l, a semi-gold wheel attached to the end of the handle attached to the body of the come-along, and There is an opening at the front of the lower part of the self-propelled vehicle for the tension wire to pass through [fits in part? The reason is that the device is configured so that it can be stored in a self-propelled vehicle via a special connection fitting.

(Embodiment) FIG. 1 is a partially cutaway external view of an embodiment of the self-propelled come-along of the present invention, and FIG. 2 is an explanatory diagram of a tensioning method using the self-propelled come-along of FIG. 1.

In the drawing, (1) is a come-along main body that can be opened and closed in a hinged manner, and has a tapered groove inside to insert a halved wedge, and an overhead wire (A) is inserted into the gripping hole.
By inserting the wedge through which the come-along body (1) is inserted into the tapered groove described in 1-, the come-along body (1) is held on the overhead electric wire (A) and can be slid onto the electric wire. (+-11 is a handle attached to the come-along main body (1), and conventionally, the tension wire passing through the semi-metal wheel for tension wire attached to the tip (+-2) of the handle was attached to the ground, etc.) The tensioning action is performed by pulling the wire with a winch or the like, but in the present invention, the tip (+-2) of the handle (+-1) is attached to the connecting metal fitting (
4) is fitted to the connecting pin (4-21), and in the state shown in the figure it is floating in the air without being pulled.
) is a lever inserted into the come-along body (+1) for attaching and detaching the wedge, and the wedge can be attached and detached by operating the wire rope 4 tied to the tip of the lever (f-3).

■ is a self-propelled vehicle located behind the come-along body (1) in the direction of travel (→ mark), and the power cable (8) (see Figure 2)
The overhead electric wire (A)-1- is self-propelled by the driving force supplied by the unit, and the come-along body (1) is moved by the push rod (2-1).
) to the specified position in the direction of the arrow.

There is a receiving part (2-2) with an opening at the front of the lower part of the self-propelled vehicle.
), and the head of the connecting hardware (4) is located in the part (2-2) of this receiver. This connecting hardware (4) has a U-shape and is attached to the head of the connecting pin (4-21 is connected to the semi-metal wheel through which the tension wire (6) (see Figure 2) passes). hook metal fittings etc.) and the above-mentioned handles (+-
1) is fitted with the tip (+-21). Therefore, in the state shown in the figure, all the weight of the tension wire (6) and semi-metal wheel (3) is connected via the connecting hardware (4). Since the vehicle is left in a self-propelled vehicle (■), these heavy fittings are not applied to the come-along body (1).

Next, the tension line 1-method using the self-propelled come-along r method of the present invention will be explained using FIG. Due to the driving force supplied by the power cable (8), the self-propelled vehicle is connected to the overhead power line (A).
J: , press the come-along main body (1), move it to a predetermined position on the overhead power line (A), and stop 1. do. After that, only the self-propelled vehicle ■ is reversed and recovered, but at this time, the head (4-1) of the connecting hardware (4) is attached to the bottom + l of the self-propelled vehicle ■.
The receiver provided on the ++ side comes off from the opening of the part (2-2), and with a force l, the handle (1-11) of the Arofugu body (1) and the semi-metal wheel (
The hook fitting (5) provided on the head of the connecting pin (4)
-21 via i+'! Connection 1 is connected, but the -force connection hardware (4) is in a loose state. This IJS 1! ! , the handle (+) is pulled by pulling the end of the tension wire (6);
-1) The force 1 on the come-along main body (1) side pushes the wedge into the mechanism, stably grips the overhead wire (A), and puts the wire in a prone state.

In addition, in FIG. 2, ω is the jump of the tension wire (6) i11. ．． O11 indicates the steel tower, GO the insulator, and 021 the metal car for the railway line.

(Effects of the Invention) According to the above-described self-propelled cut-along of the present invention, when the self-propelled vehicle runs while pressing the come-along main body, iRf and t of the tension wire and semi-gold 111 are deposited in the connecting hardware. This reduces the force 111 and the weight 111 of the along, and minimizes the friction between the wire and the wire, reducing the chance of scratches on the wire.
