It should be noted that the first tower and the second tower are only used for distinguishing two different power towers, and should not be understood as referring to a specific power tower.
The method for replacing a lead wire according to the present invention will now be described. The lead replacing method comprises the following steps:
a traction lantern ring is hung on the old lead at the first tower pole, and the traction lantern ring slides to the second tower pole along the old lead under the driving of a driving device; the traction lantern ring is fixedly connected with one end of a lead rope, and the lead rope is brought to the second tower pole from the first tower pole;

and removing the old lead from the first tower pole and the second tower pole, and replacing the old lead with a new lead.
When the method is used for replacing the lead, constructors need to climb to the upper ends of the first tower pole and the second tower pole so as to remove the old lead from the tower poles and fix the new lead between the tower poles, and the method mainly comprises the following steps:
firstly, a driving device is used for driving a traction lantern ring, and a lead wire rope is arranged between a first tower pole and a second tower pole; two ends of the lead rope can be temporarily fixed on the first tower pole and the second tower pole or not fixed;
then fixing one end of a new wire with one end of a lead rope, pulling the other end of the lead rope, and arranging the new wire between the first tower pole and the second tower pole by means of a bearing lantern ring;
and after the laying is finished, the old lead is dismantled, and the new lead and related accessories are installed on the tower pole to finish the lead replacement.
When the traction lantern ring is hung on the old lead, the old lead is arranged in the traction lantern ring in a penetrating way; the traction lantern ring is naturally hung on the old guide wire through gravity; the traction lantern ring is provided with a closable opening for the old lead to pass through; the hanging mode of the bearing lantern ring and the traction lantern ring is the same as that of the old lead.
Because of the particularity of the operation field, the driving force of the driving device is limited, and the weight of the traction lantern ring and the lead rope is light, the traction lantern ring can slide from the first tower pole to the second tower pole through the driving device; the traction lantern ring is in sliding friction with the old lead when sliding along the old lead, and the surface of the traction lantern ring is provided with a protective layer to prevent the old lead from being damaged; the bearing lantern ring has strong bearing capacity and is generally in rolling connection with the old lead when sliding along the old lead; therefore, although the new lead is fixed on the bearing lantern ring, the positive pressure on the old lead is larger, the rolling friction is formed between the bearing lantern ring and the old lead, and the bearing lantern ring can smoothly slide along the old lead.
Compared with the prior art, the lead replacing method provided by the invention has the beneficial effects that: the lead rope with light weight is arranged between the two tower poles by using the driving device and the traction lantern ring, and then the new lead with larger weight is arranged between the tower poles by using the lead rope and the bearing lantern ring, so that the lead replacing task is completed; when the lead is replaced, a constructor only needs to operate at the tower pole without erecting construction equipment below the lead, so that a large amount of manpower and material resources are saved, and the operation risk is reduced; the method can be used for efficiently and quickly replacing the lead.

When the traction lantern ring drives the lead rope to slide from the first tower pole to the second tower pole, a constructor at the first tower pole needs to pay off the lead rope and ensures that the lead rope has certain tension; if the distance between the first tower pole and the second tower pole is long, the construction personnel can hardly tighten the lead rope, the lead rope can greatly hang, and the lead rope can not be brought to the second tower pole; the above problems can be solved by providing a plurality of traction collars.
During construction, a first traction lantern ring is hung on an old lead, and one end of a lead rope is fixed on the first traction lantern ring; then starting a driving device to enable the first traction lantern ring to drive the lead rope to slide towards the second tower pole; continuously arranging traction lantern rings on the old lead according to the situation, and arranging the traction lantern rings at intervals along the length direction of the old lead, wherein the interval between two adjacent traction lantern rings is 80-100 cm under the general situation; the traction lantern ring is connected with the old lead in a sliding way and is fixedly connected with the lead rope, namely, a fixed point is arranged on the lead rope every 80-100 cm and is fixedly connected with the corresponding traction lantern ring; thus, when the first traction lantern ring reaches the second tower pole, a plurality of traction lantern rings are distributed along the length direction of the old lead, and the traction lantern rings are approximately evenly distributed. The lead wire is fixedly supported by a plurality of traction lantern rings, so that the lead wire does not hang greatly.
As a specific implementation manner of the embodiment of the present invention, the number of the load-bearing rings is plural, and the first load-bearing ring is fixedly connected to one end of the lead rope and one end of the new lead; the rest of the bearing lantern rings are arranged in a way that in the first tower pole, the rest of the bearing lantern rings are sequentially hung on the old lead at intervals in the sliding process of the first bearing lantern ring along the old lead, and the next bearing lantern ring is connected with the previous bearing lantern ring through a connecting piece; in the process of hooking the rest of the bearing lantern rings, the new lead is placed in the bearing lantern rings, so that the new lead is lapped in the bearing lantern rings; and after the bearing lantern ring is laid, the position of the bearing lantern ring along the length direction of the old lead is fixed.
Similar to the problem of the previous embodiment, when the distance between the first tower and the second tower is large, the new wire will hang down to a large extent when being brought from the first tower to the second tower by means of the load-bearing collar and the pull cord; and the new wire is typically heavier, further increasing the magnitude of the overhang. The problem of new wire overhang is solved by providing a plurality of load-bearing loops.
When a new lead is brought to a second tower pole from a first tower pole, a first bearing lantern ring is hung on the old lead at the first tower pole, and one end of a lead rope at the first tower pole is fixedly connected with the bearing lantern ring, so that the first bearing lantern ring can be pulled by the lead rope; meanwhile, one end of the new lead is fixedly connected with the first bearing lantern ring, so that the first bearing lantern ring can pull the new lead to move to the second tower pole; pulling a lead rope at the second tower pole, wherein the first traction lantern ring slides along the old conductor under the pulling of the lead rope, and the traction lantern ring is continuously arranged on the old conductor in the process according to the situation; the old lead and the new lead are simultaneously arranged in the bearing lantern ring in a penetrating way, the upper part of the bearing lantern ring is contacted with the old lead and hung on the old lead, and the new lead is lapped on the lower part of the bearing lantern ring; the front bearing lantern ring is connected with the rear bearing lantern ring through a connecting piece, so that the front bearing lantern ring can drive the rear bearing lantern ring to move towards the second tower rod; the bearing lantern ring is in rolling connection with the old lead, and the friction force between the bearing lantern ring and the old lead is small; when the first bearing lantern ring reaches the second tower pole, a plurality of bearing lantern rings are arranged at intervals along the length direction of the old lead and are approximately uniformly distributed, and the new lead penetrates through and is lapped in all the bearing lantern rings. The length of the new lead below the old lead in the air is longer and longer along with the movement of the bearing sleeve to the second tower pole; however, each time a new lead is added, a corresponding bearing lantern ring is hung on the old lead to bear the new lead, so that the new lead cannot hang greatly even if the distance between the first tower pole and the second tower pole is longer.
