Problems solved by technology
However, the existing insulator replacement fixture is locked and connected by bolts and nuts, and the thickness of the fixture components is relatively thick.
Due to space constraints, the existing insulator replacement fixtures cannot replace this kind of flower-arranged insulator strings that are inserted every four

The invention discloses an insulator replacement fixture with a locking device. The insulator replacement fixture comprises a fixture and the locking device, wherein the fixture comprises a fixture main body and a fixture cover; the middle part of the fixture main body is in a circular arc form; lug plates are arranged at two ends of the circular arc; the fixture cover is the circular arc which is equal to the circular arc in the middle part of the fixture main body in diameter; a cavity is formed between the fixture main body and the fixture cover; a latch is arranged at one end of the fixture cover and is clamped on the fixture main body; the fixture cover is connected to the fixture main body through a bolt; the bolt is arranged on the latch part of the fixture cover; the locking device comprises a locking column; through holes are formed in the fixture main body and the fixture cover; and the locking column is arranged in the through holes. The fixture disclosed by the invention is simple in structure, simple and convenient to operate, high in practicability and wide in application range.
Description
technical field [0001] The invention relates to a high-voltage line equipment replacement tool, in particular to an insulator replacement jig with a locking device. Background technique [0002] Existing fixtures for replacing insulators usually consist of fixture components and shrink components. The front cover and rear cover of the clamp assembly are usually connected by hinges and bolts; when replacing the insulator, it is usually necessary to loosen the nut first, clamp the front cover and rear cover of the clamp on the insulator, and then lock the bolts. Fasten the insulators. However, limited by the shape of the clamp assembly, it is inconvenient for workers to perform loosening and locking operations on the clamp assembly. [0003] In addition, when the outdoor temperature is low, the transmission line is in need of anti-icing work, and most of the linear suspension insulator strings and the tension tower jumper insulator strings on the line are transformed into or...
