Description

A fixture for installing color signs of transmission lines

technical field

The invention relates to a fixture for installing color signs of power transmission lines, and belongs to the technical field of power line safety technology engineering.

Background technique

In order to prevent mistaken registration of electric lines in multi-circuit lines or electrodes in DC lines on the same tower, it is required that each base tower should be provided with identification marks (ie color codes, identification marks, etc.) and dual names. Because the transmission line is exposed in the wild and exposed to wind and rain for a long time, it is easy to cause mechanical fatigue of the bolts fixing the color plate, causing the color plate to break off or the bolt hole of the color plate to be rusted and broken, so that the color plate falls from a high place, causing personnel Injury or property loss; How to improve the firmness of the color label fixing and reduce damage has become a topic that is often discussed.

The installation method of the current color signage is installed as a line accessory, and a specially processed clip is used to connect the cross-arm tower material, and a φ12 bolt is used to fix the color signage on the clip. This installation method has the following disadvantages:

One is that the long-term mechanical fatigue at the bolt position of the fixed color plate is caused by the vibration of the wind, causing the color plate to break off or the bolt hole of the color plate to be corroded and broken, and the defect rate is high;

The second is that the color sign falls from a high place, which may hurt the safety of pedestrians below;

The third is that there is no line color label at the crossarm of the power line, which may cause the possibility of mistakenly boarding the line.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a simple and reliable structure, easy to use and install, strong firmness, can save the cost of use, and greatly improve the installation fixture of the color sign of the transmission line.

The object of the present invention is accomplished through the following technical proposals. A fixture for installing color signs of power transmission lines mainly includes a cross-shaped plane clip body fixed on the cross-arm tower material of power transmission lines and capable of clamping color signs. The two lateral ends of the clamp body are respectively provided with a clamp hook that is bent forward to clamp the color label; the back of the clamp body is equipped with a fixed clamp block that is clamped to the cross-arm tower material with bolts and nuts.

The cross-shaped plane clip body is formed by connecting two strip-shaped plates, wherein the two ends of the transverse strip-shaped plates are respectively provided with clip hooks; the lower end of the vertical strip-shaped plates is also provided with clips. Hook to form a clamping structure for placing color labels on three sides.

The upper and lower ends of the vertical strip plate are respectively provided with bolt holes, in which there is at least one first set of bolts and nuts that can fix the clamping block for clamping the cross-arm tower material on the clamp body; and The first set of bolts and nuts pass through the color label, and the color label is fastened on the clip body with the first set of bolts and nuts.

The fixed clamping block is composed of two upper and lower strips bent into an angular bracket, and the two ends of the angular bracket are respectively provided with through holes, wherein each corner is close to the back of the vertical strip, and Make the through holes correspond to the bolt holes at both ends of the vertical strip plate, while the other corner of the angle bracket is arranged adjacently, and after aligning the corresponding through holes, a second set of bolts and bolts for fixing are specially arranged. nuts.

The through holes at both ends of the angular bracket are slot-shaped holes for adjustable alignment.

The fixture described in the present invention bears force at four points and is evenly stressed, avoiding the long-term mechanical fatigue at the position of the color plate bolt due to the vibration caused by the wind, which causes the rust, fracture, and fall-off of the color plate bolt hole; it has a simple and reliable structure, It is easy to use and install, strong in firmness, can save the cost of use, and greatly improves the safety of use.
