SU1198629A1 - Device for fixing wire of aerial power line - Google Patents

Description

The invention can be used for rolling electrical wires with their subsequent fixing to the supports of power lines. The purpose of the invention is to simplify and reduce the cost of installation by fixing the boats and the cage with the rollers at the same time on the suspension. The clip with raskatochny rollers is located under the boat and has an opportunity to move in the vertical direction. After rolling the wires along the rollers with the upper fixed position of the clip, the cage is lowered with the unrolling rollers, and the wire lies at the bottom of the boat and is pressed against its bottom with swivel dies attached to the hanger. After that, the clip is removed. 6 Il.

The invention relates to power engineering and can be used when laying the electrical wires of overhead power lines, in particular for hanging and fixing the electrical wires to the supports of power lines.

The purpose of the invention is to simplify and reduce the cost of installation.

FIG. 1 shows a device for fixing the wire of an overhead transmission line ^ in FIG. 2, section A-A in FIG. 1rna of FIG. 3 and 4 a device control circuit using a telescopic boom with a safety gear; figure 5 - node I in figure 4; figure 6 - section bb in figure 5.

The device for fixing the wire 1 of the overhead power line includes a boat 3 mounted on the suspension 2. The suspension rollers 5 are connected with the possibility of vertical movement of the unrolling rollers 5, which are placed in a common cage 6. In the middle of the cage 6 between the rollers 5, sleeve 7 is inserted. The lower free end of the bracket 4 is provided with a pin 8, on. which through the sleeve put the clip 6 with raskatochnyh rollers

5. Bottom holder 6 is fixed with a nut 9, worn on a stud 8. The clamping elements are made in the form of two swivel dies 10 fixed in the upper part on a common horizontal axis 11 mounted in the suspension 2. The swivel dies 10 are fitted with guide lugs 12 mated with slots 13, which are made in the body of the boat 3.

The device works as follows.

After rolling and tensioning the wire 1, it must be shifted from the rollers 5 to the boat. To do this, turn the nut 9, which in this case is lowered along the threads of the stud 8. At the same time, the holder 6 is lowered with the roll rollers. Wire 1 lies on the bottom of the boat. The weight of the wire 1 is transmitted to the axis 11, as a result of which the dies 10, moving along the slots 13, turn to each other and firmly press the wire 1 to the bottom of the boat. ^ ^ Mu 6 with rollers 5 is removed from the device, it can be

repeatedly used for similar operations.

The proposed device for fixing the wires of an overhead power line can be mounted by a fitter. However, it is possible to control using a device mounted on a vehicle 14 with a telescopic boom 15, at the upper end of which there is a double fork catcher 16 with a swivel mechanism 17 and an allen key 18.

The vehicle 14 approaches the intermediate support and is installed under the device. The boom 15 is installed in a vertical position and with the help of an optical sight, located in the lower part of the boom, is aimed at the middle of the cage 6 with the rollers. The boom extends all the way to the fork catcher 16 into the holder 6.

At the same time, as a result of the centering of the safety gear 16, the allen key 18 of the turning mechanism 17 comes into connection with the nut 9. The engine of the turning mechanism is turned on, and the nut 9 is lowered along the thread of the stud 8 together with the yoke 6. Strela

³ θ is folded, and the clip with rollers is removed from the safety device and then used for similar operations.

The proposed device allows for a continuous transition from

35 removing the wire from the rollers to put it in the clamp and fasten it in the latter, which is done with one simple action - turning the nut. Thus, at the same time, the work of the assembler-steepleader or the operator of a land vehicle is considerably simplified and accelerated and, consequently, the installation process itself is accelerated and cheapened.
