() DEVICE FOR REMOVING WIRES WITH THE HELP OF AN AIRCRAFT Yu. P. Konyukhov

one

The invention relates to energy construction and can be used in the construction of transmission lines in areas difficult to pass for land transport.

The closest in technical essence to the present invention is a device for stretching wires using an aircraft, comprising means for fastening wires connected with an external suspension of an aircraft.

The wire securing means is a frame on which the wire drum is mounted. The wire with the free end is anchored on the ground and its rolling is carried out on the support cross bars while the helicopter is moving along the power line l.

A disadvantage of such a device is that it only allows one wire to be rolled out. In addition, depending on the mass of the drum with the wire, it requires the use of helicopters of a certain capacity.

The purpose of the invention is to increase productivity.

Claims (3)

This goal is achieved by the fact that in a device for stretching wires using an aircraft, comprising means for fastening wires connected to the external suspension of an aircraft, means for fastening wires are made in the form of a vertical rack fixed to it using braces and spaced from there is a transverse beam, the longitudinal axis of which is located in a plane perpendicular to the longitudinal axis of the vertical column, with elements for free covering the wire installed at the ends of the transverse beam And the vertical rack at equal distances from the ends of the transverse beams mounted elements for fixing poovoda. In addition, the transverse beam can be made with a threaded hole along its longitudinal axis, and each of the elements for free wire enveloping is made in the form of an eyelet with a threaded end that is located in the opening of the transverse beam. Moreover, each of the elements for fi xing the wire is made in the form of a roller with a brook installed in a hinged-and-swiveling holder mounted on a vertical stand. FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, side view. . The device comprises a vertical rack 1, with which it is connected via. braces 2 transverse beam 3. The longitudinal axis of the transverse beam is located in a plane perpendicular to the longitudinal axis of the vertical support. The lugs 4 are installed at the ends of the transverse beam, the threaded ends of which are located in the longitudinal threaded hole 5 of the transversal beam 3 Heads 6 lugs k are designed to receive the wire to be rolled out (shown in dotted lines). The lugs 4 can move on the thread relative to the transverse beam 3. On the vertical upright 1, the rollers 8 with the brook are installed at an equal distance from the ends of the transverse tank 3 in the articulated case 7. The device allows two wires or cables to be rolled at the same time. Wires or cables from reel mounted on the ground, having the ability to pivot with a braking relative to the transverse axis, pass through the holes in the head of the eyelet, wind up on the roller and the ends spliced to form a loop. The ears k are preset with a predetermined center distance. Wire rolling is carried out by moving the helicopter along the line directly into the unrolling rollers with the plate caught to the side bent, which reduces the effort to pull the wire and facilitates its orientation. The connection of the wires by the ends allows them to be evenly tensioned and to prevent clinging. In addition, such an arrangement of the role of cocks 6 on the vertical rack 1 increases the reliability of fixing the position of the entire structure. When rolling the roller 8, due to the swivel holder 7, they are in the optimum position, and the free slipping of the wire in the rollers allows to evenly distribute the load from the tension of the wires. An important advantage of the device in terms of yots is that it allows the expansion of wires and cables of a large cross section. To do this, their ends from the reels are connected to a cable of a smaller cross section, which is rolled out, after which a cable of a smaller cross section, placed in the unrolling rollers, is wound onto the drum at the end of the span, pulling the main cable or wire. The device thus reduces the rolling process to a fixed position of two wires or cables, tolerance technological deviations. Thus, it allows one wire to be rolled out, if its end is to be rolled over the rollers 8 and joined into a loop. Claim 1. Arrangement for stretching wires using an aircraft, comprising means for fastening wires connected to an external suspension of an aircraft, characterized in that, in order to increase productivity, means for fastening wires are made in the form of a vertical rack attached to it with the help of braces and a transverse beam separated from it, the longitudinal axis of which is located in a plane perpendicular to the axis of the vertical column, while at the ends of the transverse beam there is an electr cients for free enclose the wire, and the vertical rack at equal distances from the ends of the transverse beams mounted elements for fixing the wire. 2. Device POP.1, characterized in that the transverse beam is made with a threaded hole along its longitudinal axis, and each of the elements for free enveloping the wire is made in the form of an eyelet with a threaded end, which is located in the opening of the transverse beam. 3. The device according to claim 1, characterized in that each of the elements for fixing the guide is made in the form of rollers with a brook, mounted in a hinged-and-swiveling casing, mounted on a vertical stand.
