The insulated pipe is mounted on the working at height equipment and moved up and down.

The disadvantage of this analogue is the high dependence of the stable position of the lifting lever on its method of placement and use, which can lead to gross violations of safety regulations when working on power lines, including towers at height.

Implementation of the utility model.

The prefabricated insulating traverse consists of vertical 1 and horizontal 2 rods made of insulating material. The horizontal rod 2 is mounted with a latch 3 from the end of the vertical rod 1, forming a T-shaped structure, while the horizontal rod 2 is mounted in a hole made in the latch 3, which, in turn, is mounted in a hole from the end face of the vertical rod 1. Ends The horizontal rod 2 is connected to the vertical rod 1 with the help of tie rods 4, while the ends of the tie rod 4 are mounted to the horizontal rod 2 with the help of horizontal clamps 5 and to the vertical rod 1 with the help of vertical clamp 6, made of dielectric material.

At least one insulating grip 7 is mounted on the horizontal rod 2 with a detachable connection.

At least two brackets are mounted on the vertical rod 1 with a detachable connection (not shown in the figures). The bracket is made in the form of a base plate 9 (see Fig. 3), connected by means of stiffeners 10 with an extension 11, made, as an option, from a hollow pipe, a clamp 12 is mounted on the opposite side of the extension 11 (see Fig. 4), made of half-rings with the possibility of placing the clamp around the vertical rod 1 and its sliding movement between the half-rings of the clamp 12 with the half-rings of the clamps 12 apart and fixing the position of the vertical rod 1 with the half-rings of the clamps 12 tightened. On the support plate 9 of the bracket, a belt 13 is mounted, containing a belt tensioner 14, made with the possibility of fastening with the help of the mentioned brackets of the traverse to the power line support.

To the opposite horizontal rod 2 end of the vertical rod 1 mounted holder 15, made in the form of a hook. Between said holder 15 and the upper bracket mounted chain hoist 16 containing a braking device (not shown in the figures). Said chain hoist 16 is detachably mounted to the holder 15 and the upper bracket using carabiners 17.

Capture 7 (see Fig. 5) is made in the form of a body 18, in the upper part of which retractable jaws 19 are mounted, while one of the jaws is mounted to the body in a hinge-spring way with the possibility of being captured into the gap between the jaws and released from the gap of the power line cable , for which a hole 20 is made in the movable sponge. In the lower part of the body 18 of the grip 7, a clamping semi-ring 8 is detachably mounted with the possibility of fixing the grip 7 on the horizontal rod 2.

All of the above-mentioned elements of the prefabricated traverse are covered with electrical insulating material, which allows working with voltages up to 10 kV.

Traverse prefabricated insulating use as follows.

The required number of grippers 7 is placed on the horizontal rod 2, equal to the number of lines on the electric support, and they are spread on the horizontal rod 2 at distances equal to the distances between the said lines on the support, and the grippers 7 are fixed on the horizontal rod 2 using clamping half rings 8.

The prefabricated insulating traverse is mounted to the support with brackets and fixed with belt tensioners 14. The clamps 12 are loosened and the horizontal rod 2 is raised with the help of the chain hoist 16 to the height of the power lines on the insulators. Upon reaching the grips 7 of the power lines, the converging jaws 19 are separated by, for example, an electrical insulating hook by the ring 20, the said lines fall into the gap between the converging jaws 19 and reduce the converging jaws 19. With further lifting of the traverse, the said lines are torn off from the insulators. The braking device of the chain hoist 16 ensures the retention of the traverse and its smooth lifting / lowering, as well as holding it at the required height. Clamps 12 are fixed and work is started on maintenance of the power line, for example, replacement or maintenance of insulators.

After completion of work, the clamps 12 are loosened and with the help of the chain hoist 16, the prefabricated insulating traverse is lowered together with the lines until the lines are placed on the insulators, after which, by spreading the converging jaws 19, the lines are released from the body 18 of the grippers 7 by the ring 20 and continue to lower the traverse.

The technical result - increasing the reliability of fastening the traverse to the support and reducing labor costs when performing work on overhead electric lines without disconnecting them from voltage, is achieved due to the fact that the traverse is held on the pole using brackets pressed to the support by belt tensioners 14, and to the traverse connected with clamps 12, while lifting and lowering the traverse is carried out with the help of a chain hoist 16, which simplifies and accelerates the lifting of the traverse using the efforts of one person. In addition, the implementation of at least a pair of brackets provides their alternate mounting / dismantling, which again allows one person to work. The sharing of brackets and chain hoist 16 minimizes external influences, such as a strong gust of wind, on the spatial position of the traverse. The use of clamps 12, made of half rings, as a locking mechanism, due to the fit of the entire inner surface of the half rings to the vertical rod 1, and the support plate 9 of the bracket, which allows the traverse to be fastened to all pole configurations through the use of a belt 13 with a belt tensioner 14, increases the reliability of fixing the position of the vertical rod 1. The use of an insulating grip 7, which allows you to fix and release the wire inside it from below without releasing the voltage, also reduces the complexity of maintaining power lines.

The connection of the traverse with the pillar support through the use of belt tensioners 14, as well as the movement of the traverse in a vertical position through the use of the chain hoist 16 can be carried out by one user, which leads to a reduction in labor costs when working on overhead electric lines.
