Abstract

FIELD: power line construction, specifically, installation of wire with use of two helicopters. SUBSTANCE: proposed process consists in preparation of wire for installation, in its laying on ground with subsequent attachment of one end of wire to external suspension of each helicopter taking part in operation. Climbing helicopters hoist ends of wire till the whole length of it is lifted from ground, helicopters draw together to safe distance, transport wire to place of installation. Then helicopters lower and fly in opposite directions from center to anchor supports gradually laying both branches of half-loop on ground till both ends of wire are brought to cables laid on ground of pulling mechanisms placed near supports beforehand. EFFECT: provision for accelerated installation of wire in extended spans. 2 dwg

Description

 The invention relates to energy construction, in particular to methods for mounting wire overhead lines (VL) power transmission using aircraft, mainly two helicopters.
 A known method of mounting the wire with two helicopters, namely, that the wire is hooked to the external suspension of the helicopters, lifted from the ground and transported to the installation site, where, after completion of the installation operations, the helicopters are uncoupled and the wire is finally tensioned (RF patent N 2091944, class H 02 G 1/02, 1996). The method provides the ability to install wire in difficult-to-pass over-ground spans of great length and eliminates wire contact with obstacles. However, this method does not have a high enough performance, since the mass of the wire being mounted does not exceed the carrying capacity of only one helicopter, at a relatively high cost of time due to the non-simultaneous start of two helicopters and its sequential completion.
 The closest in technical essence to the method of mounting the wire using two helicopters is also known, namely, that the wire is hooked to the external suspension of the helicopters, it is lifted and transported to the installation site, where, after the laying of the wire, the helicopters are uncoupled (US patent N 3042385, cl 258-1.2, 1959). This method allows you to block twice as large (compared with the previous method) spans, because the work is carried out with a double supply of wire, since both helicopters can pick up the amount of wire by weight equal to their carrying capacity. However, this method also has a low productivity. This is caused by a wire hooking scheme in which one end of the wire is left on the ground, the middle of the wire being mounted is attached to the first helicopter, and the other end of the wire is attached to the second helicopter. As a result, at the first stage, the layout of half the supply of wire is carried out only by the first helicopter, and the second helicopter at this time performs an auxiliary (unproductive) operation to transfer the other half of the supply of wire. After laying half of the wire, the first helicopter is disconnected from the middle of the wire, and the other half of the wire is laid by the second helicopter. Therefore, the installation process is stretched over time. At the same time, there are situations when it is necessary to quickly mount the entire supply of wire, hooked to the external suspensions of both helicopters.
 The objective of the present invention is to achieve a technical result, expressed in the possibility of accelerated installation of the wire in long spans.
 The essence of the invention lies in the fact that in the method of mounting the wire using two helicopters, in which the wire is hooked to the external suspension of the helicopters, it is picked up and transported to the installation site, where after it is laid, the helicopters are uncoupled, it is proposed to hook one of the ends of the wire to each helicopter unfolded on the ground, raise these ends with helicopters to form a half-loop, bring the helicopters closer to a safe distance and, keeping it, transport the wire, hover over the installation site, lower the helicopters push the lower half of the half-loop to the ground, then lay both branches of the half-loop by moving the helicopters above the installation site in opposite directions with a decrease, attach the ends of the wire to the cables of the traction mechanisms installed on both sides of the installation site, pre-tension the wires with these mechanisms and unload the external suspensions helicopters, unhook the ends of the wire from them, and then (after the helicopters have left) perform the final tension of the wire with traction mechanisms.
 In FIG. 1 - 2 show the sequence of operations.
Helicopters 1 and 2 take part in the implementation of the method. Previously, a wire is unwound from the drum at the training ground, its required quantity is measured, and its ends are prepared for installation: tension clamps are installed, bypass cables are pressed in, etc. Prepared wire 3 is laid out on the ground. When the helicopters 1 (position A 1 ) and 2 (position A 2 ) hang over it, the opposite ends of wire 3 are hooked to their external suspensions with locks 4 and 5, by climbing and converging the helicopters 1 (position B 1 ) and 2 (position B 2 ) lift the wire 3 from the ground to form a half-loop (see Fig. 1). In this case, the distance between the helicopters is set to minimum (based on the need to reduce the pulling forces from the side of wire 3 and thereby facilitating the control of the helicopters in flight), but sufficient to ensure flight safety (for example, at least one rotor diameter). Observing this distance between the helicopters, the wire 3 is transported to the installation site, for example, to the section of the overhead line between the anchor supports 6 and 7, also prepared for installation work. The preparation of supports 6 and 7 consists in securing the mounting rollers 8 and 9 on them, as well as in the installation of traction mechanisms 10 and 11 next to them, for example, winches, tractors with winches, etc. The cables 12 and 13 of these mechanisms are driven onto the rollers, respectively 8 and 9, they are released to the required length and their free ends are laid on the ground at a distance that ensures a safe reduction of the helicopters near the supports 6 and 7. After the helicopters 1 and 2 hang over the overhead line, they are brought to this position (positions B 1 and B 2, respectively ), in which the lower part of the half-loop is about water 3 will lie on the ground in the middle of the span between supports 6 and 7. If there are intermediate supports 14 in the anchor span (see FIG. 2), wire 3 is laid next to them. Then the helicopters are moved from the middle of the span in opposite directions with a decrease, gradually laying both branches of the half-loop on the ground. Moving the helicopter 1 to the support 6 (position G 1 ), and the helicopter 2 to the support 7 (position G 2 ), attach the ends of the wire 3 to the cables 12 and 13 of the traction mechanisms 10 and 11, respectively. Turning on the traction mechanisms 10 and 11, carry out the preliminary tension of the wire 3 to unload the external suspensions of both helicopters. In the presence of intermediate supports 14 raise the wire 3 to their traverse. After that, having opened the locks 4 and 5, the helicopters are uncoupled from wire 3 and they fly off to land. Then, the final tension of the wire 3 is carried out, it is pulled by the mechanisms 10 and 11 to its ends to the cross-arms of the supports 6 and 7, where they are attached to the garlands of insulators, bypass cables are fixed, etc.
 The proposed method provides accelerated installation of the wire. It is also possible to simultaneously install several wires in one flight, for example, three with a split phase, or three phases at once, three wires in each. In addition, this method can be used in emergency recovery work, for example, in the restoration of cable cars, suspension bridges, etc.
