Description

Lightning rod mounting bracket

technical field

The utility model relates to a device for installing a lightning rod on a power transmission line tower, in particular to a lightning rod mounting bracket. the

Background technique

The line-type zinc oxide lightning rod can protect the line insulator from flashover in the case of lightning strike. The zinc oxide lightning rod is applied to the transmission line, which can effectively prevent the line from tripping due to lightning strike and improve the reliability of the transmission line. The common method for installing line-type zinc oxide lightning rods on towers is to drill holes in the cross-arm angle steel of the tower, and then connect the lightning rod and its counting bracket to the cross-arm. It is necessary to drill several holes to install a lightning rod. The hole machine is inconvenient to operate and increases the risk of work. the

Contents of the invention

The purpose of this utility model is to provide a lightning rod mounting bracket for the above-mentioned deficiencies in the prior art, which has the advantages of light weight, portability, and quick installation, can improve work efficiency, and ensure the safety of high-altitude operations. the

The utility model is realized in this way: it includes two right-angled inner and outer brackets which are respectively composed of vertical splints and horizontal splints, and the corresponding positions of the vertical splints and the horizontal splints of the two inner and outer brackets are respectively provided with connection holes, and the outer brackets There is a mounting hole connected to the lightning rod counter bracket on the vertical splint of the outer bracket, and a downwardly protruding connecting plate is provided under the outer support, and a mounting hole connected to the lightning rod is opened on the connecting plate. When installing, place the inner and outer brackets on the right-angled inner and outer ends of the cross arm of the tower respectively, fix and clamp them with bolts, and then install lightning rods and counters on the brackets. The installation operation is very convenient. the

The utility model adopts a special bracket to be fixed on the cross arm of the pole tower, which is convenient and quick to install, can improve work efficiency, and ensure the safety of high-altitude operations, and the bracket has the advantages of light weight and portability. the
