The beneficial effect is that the wire overhead winding device is a hollow steel column covered with epoxy Composed of resin, the quality is far smaller than that of existing insulators.

In order to achieve the above purpose, the utility model provides the following technical solutions: a portable wire winding device for overhead lines in power grids, including a hollow column, the end plate of the hollow column and the top plate are connected by fastening bolts, and the top plate is set There is a lightning protection column, the surface of the hollow column is provided with a cap plate, and a double wire slot is provided between the cap plate and the cap plate, bolt holes are provided on the bottom plate and the backing plate of the hollow column, and the bottom plate, the backing plate It is connected with the cross arm by fastening bolts. There is a wire hole between the end plate and the top plate. A drainage column is arranged inside the lightning protection column, and the drainage column and the steel column are grooved. The inside of the hollow column A reinforcing rod is provided.

Preferably, the cross arm is fixed between the bottom plate and the backing plate.

Preferably, the cap plate is made of epoxy resin material, and the distance between the cap plates is 80mm.

Preferably, an arc striking rod is installed between the end plate and the top plate.

Preferably, the hollow column is made of stainless steel components.

Compared with the prior art, the beneficial effect of the utility model is: the equipment is easy to install, and the lightning protection column is installed on the fixed plate, so that the insulator has a certain protection ability for the surrounding electric wires in thunderstorm weather, and the hollow column There is a reinforcing rod inside, which greatly improves the mechanical strength of the insulator, and the surface of the hollow column is covered with epoxy resin, replacing the traditional ceramic or tempered glass, and the huge column enhances the cold and heat resistance of the insulator performance, corrosion resistance and lightning strike resistance, and greatly reduce the weight of the insulator.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1 and Fig. 2, an embodiment provided by the utility model: a portable wire winding device for overhead lines of electric power grid, comprising a hollow column 11, the end plate 8 and the top plate 2 of the hollow column 11 are fastened Bolts 7 are connected, and the top plate 2 is provided with a lightning protection column 1, the surface of the hollow column 11 is provided with a cap plate 3, and a double wire groove 4 is provided between the cap plate 3 and the cap plate 3, the bottom plate 5 of the hollow column 11 and the pad Bolt holes are provided on the plates 10, and the bottom plate 5, the backing plate 10 and the cross arm 6 are connected by fastening bolts 7, the end plate 8 and the top plate 2 are provided with wire holes 12, and the interior of the lightning protection column 1 is provided with drainage The column 13, and the groove connection between the drainage column 13 and the steel column 14, the hollow column 11 is provided with a reinforcing rod 15, the cross arm 6 is fixed between the bottom plate 5 and the backing plate 10, the cap plate 3 is made of epoxy resin material, And the distance between the cap plate 3 and the cap plate 3 is 80 mm, an arc striker 9 is installed between the end plate 8 and the top plate 2, the hollow column 11 is made of stainless steel components, and the surface of the hollow column 11 is covered with an epoxy resin surface layer , enhance the cold and heat resistance, corrosion resistance and lightning strike resistance of the insulator, and reduce the weight of the insulator.

Working principle: When in use, the insulators should be checked first when the insulators are installed, and to ensure that the insulators used are qualified products, the staff will carry the insulators to the upper end of the tower, and insert the main body under the bottom plate 5 of the hollow column 11 into the In the through hole of the cross arm 6, align the screw holes on the backing plate 10 with the screw holes on the bottom plate 5 and the cross arm 6, install it on the cross arm 6 with fastening bolts 7, and pad the bolts There is an anti-drop gasket. If the overhead wire is a single strand, it can be seen that the wire is placed in the wire hole 12 between the top plate 2 and the end plate 8. In thunderstorm weather, the lightning protection column 1 can attract the lightning that lands on the side of the wire. , the lightning current can flow through the tower through the diversion column 13 and the hollow column 11, and then conduct to the ground to protect the wires. If the wires guided by the insulator are multi-strand, the wires can be wound around the cap plate 3 and the cap plate In the double wire groove 4 between 3, can prevent that wire is blown away from tower by wind.
