Description
Technical field
The utility model relates to a kind of line lifter.
Background technology
At present, the instrument of replacing overhead ground wire wire clamp mainly is the 8# iron wire.With the 8# iron wire overhead ground wire and wire clamp hanging point place are coupled together during replacing.Through continuous winding 8# iron wire the overhead ground wire wire clamp is raised up, treat to carry out when its lifting reach a certain height the replacing of overhead ground wire wire clamp.But method poor reliability, the efficient of this replacing overhead ground wire wire clamp are low, easy damaged ground wire and poor stability.
The utility model content
Method poor reliability, the efficient of changing wire clamp at present are low in order to solve for the utility model, the problem of easy damaged ground wire and poor stability, and then a kind of overhead ground wire line lifter is provided.
The utility model is to address the above problem the technical scheme of taking to be: a kind of overhead ground wire line lifter of the utility model comprises threaded rod, swivel nut, deck, carry that line colludes and bearing pin; One end of threaded rod is with to carry the end that line colludes hinged through bearing pin; Threaded rod is threaded with swivel nut, and deck is at swivel nut and carry between line colludes, and an end of deck is provided with first open slot along the deck thickness direction; Threaded rod passes first open slot on the deck; Deck and threaded rod are slidingly connected, and the other end of deck is provided with second open slot along the Width of deck, and a side channel sidewall of second open slot is provided with screwed hole.
The beneficial effect of the utility model is:
1, adopt the method for traditional replacing overhead ground wire wire clamp, 1 operation personnel can only accomplish the replacing of the overhead ground wire wire clamp of 3 basic shaft towers in one day, about 35 minutes consuming time of the replacing of average every basic shaft tower overhead ground wire wire clamp; Adopt the line lifter of the utility model; 1 operation personnel can accomplish the replacing of the overhead ground wire wire clamp of 4 basic shaft towers in one day; About 20 minutes consuming time of the replacing of average every basic shaft tower overhead ground wire wire clamp, the operating efficiency of every day has improved 33%, and every basic shaft tower wire clamp replacing time has economized 43%.
2, owing to carry line and collude with the contact area of overhead ground wire greatlyyer, reduced damage to overhead ground wire than iron wire; Simultaneously, because the mechanical strength of deck and threaded rod all will be higher than the mechanical strength of iron wire, wire clamp is changed safe and reliable.
