Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary hardware for pole tower guy wires, in particular to a fixing device for a pole tower guy wire tail wire. Background Art

[0002] The guy wire is set up to stabilize the pole tower. The guy wire can balance the tension in all directions of the pole tower, so that it does not bend or fall, so as to ensure the safe operation of the lines or equipment on the pole tower. At present, when the pole towers in the power industry use steel stranded wire (LGJ) as the guy wire, the tail end of the guy wire is usually tied with a single strand of iron wire or aluminum wire by repeated manual winding. This is the most primitive method to fix the tail end of the guy wire. The advantages of this binding and fixing method are that it is easy to obtain materials and affordable; the disadvantages are that it is neither beautiful nor safe, the construction is laborious and laborious, and due to the differences in the construction technology of the operators, it cannot fully meet the requirements of technical standards and regulations.

[0003] In addition, as time goes by, the tie wires will be damaged to varying degrees or even lost. There are two main reasons: First, the galvanized coating of the iron tie wires is damaged during the binding process. The tie wires are exposed to the wild all year round and are affected by climate, environment, humidity and other factors. The tie wires will rust, corrode, break and other problems. Generally, after 3-5 years, the damaged tie wires need to be reinforced or replaced; second, the tie wires are only tied by winding the two ends together and tightening them, without any defense function, and are repeatedly damaged or even stolen.

[0004] As the binding wires are damaged, at the very least, it may cause the pole tower to tilt, endangering the safety of the lines or equipment on the pole tower. At worst, it may cause the pole tower to collapse, causing serious property losses to the country and endangering the lives of the people. Utility Model Content
