SU1488904A1 - Method of laying out wires along electric power transmission lines - Google Patents

Description

The invention relates to power engineering and can be used in the construction of overhead power lines. The goal is to increase productivity by enabling the layout of wires with the help of an aircraft. The wires 1 rolled out on the ground platform are doubled, the roller 2 and the sling 3 are fixed, the tension clamps 4 are attached to the ends of the wires 1 and the weight 5 is attached with an additional

by sling 7. Then, through roller 2, ”wires 1 are fastened to the suspension 8 of the helicopter 9, which moves the wires .1 to support 6. Cords of wires 1 are fixed to support 6, after which the helicopter 9

flies to the next support, pulling the wires 1. The method provides an increase in the productivity of work due to the possibility of the layout of several wires at once. 2 Il.

The invention relates to energy, in particular to methods of laying wires along overhead power lines for the subsequent installation of wires on supports, as well as ropes 15 aerial cableways using an aircraft mainly in difficult conditions.

The purpose of the invention is to improve performance by providing 20 possibilities of the layout of the wires using an aircraft.

FIG. 1 Shows the preparation of three wires for layout along

overhead power line in the proposed method; in fig. 2 'diagram of the method of the layout of three wires simultaneously using an aircraft along an overhead transmission line, made by the proposed method.

The layout of the wires is as follows.

The wire (wires) 1 is rolled out on a nano-land platform (not shown), then it is bent twice and a roller 2 with a sling 3 is installed at the point of inflection so that the wires 1 bend around roller 2. The ends of each of the wires 1 are pressed together with tension clamps 4, then equip with a load 5 of a non-engaging form, which is fixed by one condom directly to the tension clamps 4, and the other end to wires 1 so that its length of wires 1 1 is poor and equal to the height of support 6 of the transmission line. In the place of attachment of cargo 5 to the wires 1, an additional sling 7 is attached. After that, the roller 2s 50 is attached by a sling 3. they attach to the external hanger 8 of the helicopter 9, then the helicopter 9 transports the wires 1 to the place of the beginning of the layout at the support 6, decreases, laying the ends of the wires 1 55 together with the load 5 on the ground in close proximity to the support 6.

The ends of the wires 1, provided with an additional line 7, are disconnected from

cargo 5 and attached with this line to the support 6. Then the helicopter 9 pulls the wires 1 to the separation of cargo 5 from the ground and moves with a decrease along the power line to the next support, producing the layout of the wires 1. At the end of the layout roller 2 is unhooked from the external suspension 8 and free it from wires 1. A free segment (supply) of wires 1 at the first support 6 is necessary for lifting the ends of the wires 1. on a support for their further installation on it.

I

The proposed method allows the layout of both one and several wires simultaneously.

The proposed method of layout of wires provides compared with the known ability to install wires on overhead power lines in difficult conditions and in mountainous areas with large differences in height, and also improves the performance of work on the layout of wires due to the simultaneous layout of several wires.

Claims (1)

Claim The method of arranging the wires along the overhead power lines, which consists in rolling, cutting the wire into measured areas on the ground platform and pressing the ends of the wire sections with tension clamps, characterized in that, in order to improve performance by allowing the layout of the wires using an aircraft, each dimensional the wire sections on the ground platform are doubled; a roller with a sling is installed at the point of inflection; both ends of the wire section are fixed to the load, one end of which is so as to leave free a segment length equal to the height of the support 1488904 6 lines, in the place of attachment of this end to the cargo, attach an additional line to anchor the end of the wire section at the beginning of the layout, attach the roller to the external suspension of the aircraft, after transporting the wire section to the support with a rear line from the load, attach the additional line to the support, carry out further movement of the aircraft with a decrease, spreading the wire section along the power line to the next support, then disconnect the roller from the external hanger
