Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

Embodiment 1：

Referring to shown in Fig. 1-3 and 5, the utility model embodiment 1 discloses a kind of tower bar with reinforced cross-arm, including Tower bar ontology 5 and the reinforced cross-arm being fixedly arranged on the tower bar ontology 5, the reinforced cross-arm include angle steel cross bar 1, positioning Ring 2 and reinforcement structure, the positioning ring 2 is sheathed on the angle steel cross bar 1 and is fixedly connected with the angle steel cross bar 1, described It includes connecting the angle that a circle is provided on the outer peripheral surface of positioning ring 2 for placing the groove a of steel wire cable, the reinforcement structure The stiffening plate 3 of two right-angle sides of the place section that steel cross bar 1 is connect with the positioning ring 2, wherein the stiffening plate 3 and institute State the intensive aspect for being collectively formed that section is triangular form after angle steel cross bar 1 connects.

Preferably, the inner ring of the positioning ring 2 is installed with strengthening rib strip 6, the strengthening rib strip 6 and the angle steel cross bar 1 Right-angle surface be fixedly connected.The intensity of positioning ring 2 can be increased by increasing strengthening rib strip 6.

Preferably, the surface of the groove a on the positioning ring 2 forms texture structure by embossing processing, alternatively, described fixed The surface of groove a on the ring 2 of position is coated with anti-skid wearable coating.By the way that texture structure and anti-skid wearable coating is arranged all on groove It is the frictional force for increasing positioning ring and steel wire loop, avoids having skidded phenomenon in tow.

When replacing insulator, steel wire loop is placed in positioning ring 2, the lifting tools such as cucurbit are connected by steel wire loop To hang down old insulator, new insulator is hung on.Positioning ring 2 is arranged can be to avoid the direct of angle steel cross bar 1 and steel wire loop Contact, thus steel wire loop is prevented to be cut, to reduce dangerous hidden danger.Groove on positioning ring 2 can further fix steel Cord set, prevents the movement of steel wire loop, and then increases stability.Stiffening plate 3, which is arranged, can increase the intensity of cross-arm, prevent It bends, fracture when only lifting by crane insulator, to improve safety.
