Abstract
The utility model relates to the technical field of overhead transmission line equipment in power industry, in particular to a hinged connecting hardware of lead-alternated anti-waving spacing rod. The existing connecting hardware has rigid connection; when the transmission line waves, the tensile force, compressive force and distortional force generated between the lead-alternated spacing rod and the connecting hardware is extremely great so that a supporting frame used for connecting the hardware breaks, thus causing severe accidents such as tripping and shutdown of lines and broken leads, and the like. The technical scheme is characterized in that a pulling plate of the supporting frame is connected with an adjusting plate of the supporting frame; a connecting base of the adjusting plate of the supporting frame is hinged to a right-angled hanging plate; the other end of the right-angled hanging plate is hinged to a bowl-head hanging plate; and the bowl head of the other end of the bowl-head hanging plate is provided with a groove angle. The hinged connecting hardware utilizes the structure of hinge and bowl-head groove angle to release the distortional force generated by the alternated spacing rod and the connecting hardware in the waving process of the lead, and avoids damaging the alternated spacing rod and the connecting hardware due to the tension force, compressive force and distortional force.
Description
Technical field
The utility model relates to power industry overhead transmission line equipment technical field, and the anti-hinge type of waving inter-phase spacer of specifically a kind of lead connects gold utensil.
Background technology
The reason that transmission line is waved is multiple, as wind excitation, wire icing, line construction etc.When the condition of waving forms, conductor galloping will be done directed awave vibration, and the point on the conductive wire cross-section is being projected as ellipse perpendicular to the movement locus on the plane of lead trend; Because the lead of waving fluctuates greatly, and rock, a last very long, be created in the lead inter-phase spacer and connect drawing of gold utensil, the pressure active force is very big, because being rigidity, present widely used connection gold utensil connects, inter-phase spacer and connection gold utensil are when conductor galloping, root at conductor spacer middle part and connection gold utensil produces very big distortion power, the bracing frame that connects gold utensil is ruptured, the phase spacing ability of inter-phase spacer lead out of hand, cause the alternate tripping operation power failure of circuit or cause the burn lead, forget about it shaft tower, lead serious accident such as fracture, thus heavy economic losses caused.
Summary of the invention
The purpose of this utility model provides the anti-hinge type of waving inter-phase spacer of a kind of lead and connects gold utensil, has overcome the deficiencies in the prior art, has solved the flimsy problem of connection gold utensil of inter-phase spacer, has effectively guaranteed the normal operation of transmission line.
The technical solution of the utility model is: be made up of bracing frame adjustment plate, right angle link plate, socket-clevis eye, bracing frame arm-tie; Bracing frame is adjusted the plate middle part and is connected with Connection Block, and bracing frame is adjusted plate two ends connecting portion respectively one group of adjustment hole C; The bracing frame arm-tie passes adjustment hole with bracing frame adjustment plate by bolt and is connected; It is hinged that Connection Block and right angle link plate pass connecting hole A by bolt; It is hinged that the other end of right angle link plate and socket-clevis eye pass connecting hole B by bolt; The other end of socket-clevis eye is connected with the bowl head that has groove angle; But socket-clevis eye is the pincerlike plate by two foldings to assembly, and is equipped with lock(ing) bolt and pin; Connecting hole A is vertical mutually with the center line of connecting hole B.
The utility model has the advantages that: connect gold utensil when lead is waved, utilize articulated structure in Different Plane, to produce the anglec of rotation, the release lead to inter-phase spacer and the connection distortion power that gold utensil produced, is avoided inter-phase spacer and is connect the damage that gold utensil causes owing to tension, pressure, distortion power in the process of waving.
