ANCHOR BRACKET FOR FASTENING ANCHOR CLAMPS OF SELF-CARRYING ISOLATED WIRES OF ELECTRIC TRANSMISSION AIR LINES

The utility model relates to the field of electric power industry, in particular, to anchor brackets for fastening anchor clamps of self-supporting insulated wires of overhead power transmission lines.

Known anchor bracket, which is a profile body with a base in the form of a flat plate, made with the possibility of mounting to a support and ending in the upper part with a single-footed eye with an element for attaching an anchor clamp, and the element for attaching an anchor clamp is made in the form of an opening for accommodating the thimble of the anchor cable clamp and having a circular arc in the upper part [1].

The main drawback of this technical solution is the structural complexity of both the anchor bracket and the anchor clamp itself, which significantly limits its industrial use on overhead power lines.

The closest technical solution to the proposed one is the anchor bracket for fastening the anchor clamps of self-supporting insulated wires of overhead power lines, made in the form of a single structure containing a rectangular base with an internal slot for the mounting tape and at least one hole for the fastening element of the anchor bracket to the wall of the building, as well as a rectangular flat working part connected at an angle to the base with a hole for attaching at least one black clamp, and the hole for mounting the anchor clamp in the working part is L-shaped, where its vertical part is placed in the center of the working part parallel to its side sides, and the horizontal part is made in the form of a slot in the direction from the side of the working part to the central part of the hole [ 2].

In this closest analogue with respect to the proposed angle between the planes of the base and the working part of the anchor bracket is 60 ° and this value is not optimal in certain cases, since the point of suspension of the wire on the anchor bracket relative to the input equipment to the subscriber can be located as above and below.

The applicant set a specific goal, namely to develop an anchor bracket for fastening the anchor clamps of self-supporting insulated wires of overhead power lines, characterized by the versatility of practical use for a wide range of possible options for hanging the wire on the anchor bracket relative to the input equipment to the subscriber (it is possible to produce various modifications of the anchor bracket with different angles of wire suspension). This positive technical result was achieved due to the combination of essential structural features of the anchor bracket for fastening the anchor clamps of self-supporting insulated wires of overhead power lines and made in accordance with the present utility model and given in the following formula: “anchor bracket for fastening the anchor clamps of self-supporting insulated wires of overhead power lines made in the form of a single structure containing a rectangular base with an inner surface a thread for the mounting tape and at least one hole for the fastening element of the anchor bracket to the wall of the building, as well as a rectangular flat working part connected at an angle to the base with a hole for attaching at least one anchor clip, the hole for attaching the anchor the clamp in the working part is made L-shaped, where its vertical part is placed in the center of the working part parallel to its lateral sides, and the horizontal part is made in the form of a slot in the direction from the side of the working part to the central part of the hole; when the wire suspension point is located relative to the subscriber input equipment below the anchor bracket, the angle between the base planes and the rectangular flat working part is selected from a maximum value of 59 ° to angle values less than 59 °, and when the wire suspension point is located relative to the subscriber input equipment above the anchor bracket, the angle between the planes of the base and the rectangular flat working part is selected from a minimum value of 61 ° to angle values greater than 61 °. "

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows an anchor bracket for fixing anchor clamps of self-supporting insulated wires of overhead power lines, made in accordance with this utility model, isometric view; in FIG. 2 is a schematic view of the attachment of the anchor bracket of FIG. 1 to the wall of the building at an angle of deviation of its working part from 59 °; in FIG. 3 is a schematic view of the attachment of the anchor bracket of FIG. 1 when the angle of deviation of its working part from 61 °.

The inventive anchor bracket for fastening the anchor clamps of self-supporting insulated wires of overhead power lines is made in the form of a single structure, which contains a rectangular base 1 with an internal slot 2 for a mounting tape (not shown) and a hole 3 for an element for attaching an anchor bracket to a building wall. A rectangular flat working part 4 is connected to the base 1 at an angle, having a L-shaped hole 5, intended for fastening one or more anchor clamps. The L-shaped hole 5 has a vertical part 6 located in the center of the working part 4 parallel to its lateral sides 7, 8, and a horizontal part 9 made in the form of a slot in the direction from the side 8 of the working part 4 to the central part of the hole 5.

When the suspension point of the wires relative to the input equipment of the subscriber is lower than the anchor bracket, the angle between the planes of the base and the rectangular flat working part is selected from a maximum value of 59 ° to angle values less than 59 ° (Fig. 2). When the suspension point of the wires relative to the input equipment of the subscriber is higher than the anchor bracket, the angle between the planes of the base and the rectangular flat working part is selected from a minimum value of 61 ° to angle values greater than 61 ° (Fig. 3).

The proposed anchor bracket is a universal design from the point of view of its widespread use at electric power facilities of various functional purposes, namely, it provides fastening of self-supporting insulated wires of overhead power lines regardless of the height at which the point of suspension of wires is located relative to the input equipment to the subscriber, due to release of modifications with different angles of arrangement of the working part 4 relative to the base 1.
