Description

(L5203J

The present invention relates to a device for fastening overhead line wires on insulators or the like by means of binding wire.

The invention consists in that in a correspondingly slotted and in its interior tube parts provided with grooved inserts one also provided with grooves and one Eccentrically arranged, conical nose-bearing insert can be swiveled and pulled out is provided, with the overhead wire introduced through the slot in the pipe part, the binding wire placed around the insulating cap or the like is wound up by turning the nose.

In the drawing, the subject matter of the invention is shown, for example, namely show Fig. X and 2 the handle in different directions, Fig. 3 and 4 the insert piece as well in different views, Fig. 5 the device before the insertion of the conductor wire, Fig. 6 shows the device during the insertion of the wire, Fig. 7 the device after insertion of the wire before use, Figs. 8 and 9 the device during use in side and front view.

The device consists of a handle (Fig. I, 2) and the replaceable insert located in it (Fig. 3, 4). The handle is a lengthwise slit tube α, which has an attachment δ at one end, which is provided with two bores c, d with nut threads to accommodate two handles e, f (Fig. 8) '. The slot of the tube α of the handle is kept wider than the possibly largest line cross-section to be tensioned. Inside the handle, two inserts g, h provided with grooves on the inside are fastened by screws i, j, k, I opposite the slot in the tube α. The insert g protrudes from the tube α . The inserts g, h are exchangeable in accordance with the respective tensioned line cross-sections of the overhead line wire.

The removable and exchangeable insert is located in the handle (Fig. 3, 4). The insert consists of the two parts n, 0, which are connected to one another by the rod m. Both parts η, ο are provided with longitudinal grooves fi, q in accordance with the tensioned line cross-sections of the overhead line wire δ.

The part η of the insert carries a conical nose in a bore or bearing made parallel to its longitudinal axis,

which is secured against falling out by the pin s. The nose ν can be rotated about its axis, so it acts at the same time as a roller and is arranged eccentrically in the part η of the insert.

Before use, fasten the slot inserts g, h corresponding to the cross-section of the overhead wire t in the handle (Fig. I, 2) by means of the screws i, j, k, I and insert the corresponding cross-section of the wire to be wrapped into the tube α Insert (fig. 3, 4). This is achieved by placing the insert on the handle in such a way that the groove insert g falls into the slot (groove) q of the insert part 0 , and then pushes the entire insert (Fig. 3, 4) into the handle so far until the part of the insert carrying the conical nose r rests against the free end of the handle. ao Fig. 5 shows the handle with the half-inserted or half-extended insert. Equipping the handle with the inserts g, h and as corresponding to the wire cross-sections to be clamped enables the device to be used for all possible overhead line cross-sections.

Overhead line wires are fastened to insulators as follows: The binding wire u (Fig. 8) is placed around the neck of the insulator as when fastening with pliers and both ends are bent back over the line. Now pull the insert (Fig. 3, 4) out of the handle until it can be turned (Fig. 5) and turn it until its groove inserts g, h with the slot in the tube α of the handle (Fig. 2) match. The device is now placed on the wire (Fig. 6) in such a way that the insert part carrying the conical nose r comes to rest against the insulator and the wire t in the grooves p, q of the two insert parts. The handle is then turned until the slot insert g corresponds to the slot fi of the insert part η and the insert is now pushed back into the handle (Fig. 7). The device is now attached to the line and rotatable on it.

Now you grasp the binding wire with the device in such a way that it is wedged between the conical nose or roller r and the line t , put it back a little over the nose r and now turn the device on the line with the handles e, f, by simultaneously applying pressure in the direction against the isolator. The binding wire u is now wound or rolled onto the line t by the conical nose r , with the formation of this nose r as a roller avoiding greater friction losses and damage such as stalling or twisting the wire or rope. After fastening the collar on one side of the insulator, pull the insert back out of the handle until it can be twisted and turn it until its slots f, q coincide with the slot α of the tubular part of the handle. The line is now free, the device is removed and attached to the line on the other side of the isotator. The collar is made in the manner just described, whereupon the device is removed.

As a result of this handling of the device, the use of any pliers device is avoided and are therefore damage to the line by stalling or twisting, as is the case with the previously customary fastening with the Forceps are inevitable, completely excluded.

As a result of the conical design of the nose r acting as a roller, a likewise conical gap is formed between the line wire t and nose r , which allows the use of different binding wire thicknesses within certain limits.
