Wooden pole intersection tie-down

Abstract

The invention provides a binding device for wooden poles, which comprises a U-shaped metal frame, a steel wire rope and a steel wire rope fixing piece. The wooden rod binding device of the present invention uses a U-shaped metal frame as a supporting point, uses a steel wire rope as a winding tool, and finally uses a steel wire rope fixing part to lock the steel wire rope, so that various materials are combined into a binding system to complete the binding process. The wooden pole binding The device has completely changed the traditional iron wire binding method, successfully avoiding the dead knot of the iron wire binding in the prior art, and the breakage of the iron wire caused by excessive tightening force, thereby preventing the iron wire from being broken due to the fatigue strength limit of the binding or due to torsional force. The twisting of the ambassador caused the collapse of the spanning frame, which completely eliminated the safety hazard of the spanning frame collapse and ensured personal safety and the safe operation of the spanning object. After the successful development of this achievement, it was immediately put into the field and received unanimous praise from the construction personnel during the field use.

Description

technical field [0001] The invention relates to the technical field of power transmission line equipment, in particular to a binding device for wooden poles. Background technique [0002] During the wiring construction of transmission lines, it often crosses low-voltage lines, 10kV lines, 35kV lines, 110kV lines, 220kV lines and other live lines or communication lines, dirt roads, highways, railways, expressways, orchards, vegetable greenhouses, garden flowers, etc. Lower the span. In order to protect its normal operation during the spanning, we will build spanning frames of different heights and spans according to the different spanning objects. like figure 1 As shown, when erecting the spanning frame, each intersection needs to be bound with iron wire. But there are following two problems in iron wire binding. [0003] On the one hand, the iron wire must have a dead knot when binding, which is easy to cause the iron wire to break, and it is not easy to be found. The i...

AI Technical Summary

Problems solved by technology

The iron wire is bound and knotted, and when the torsion force exceeds the strength limit of the iron wire after tightening, it will cause the iron wire to break. The most terrible thing is the invisible break, which is not easy to be found. In this case, the spanning frame will cause a flat bar after being stressed Sliding down along the pole, the lashing will loosen, resulting in the collapse of the spanning frame, which will not only cause the object to be spanned to fail to operate normally, affect the power supply, but also may endanger personal safety and cause serious consequences

[0004] On the other hand, the cost of the iron wire used for erecting the spanning frame by the iron wire binding method is too high

During the wiring construction process, due to the large number of objects to be crossed, the amount of iron wire used is also relatively large. According to statistics, the smallest line construction company in Hebei costs as much as 182,560 yuan per year for the iron wire used to erect the spanning frame. It can be seen that the required quantity is large. , Invisibly increased the huge construction cost

Moreover, when the spanning frame is dismantled, the wooden poles and bamboo poles used can be reused, while the iron wires used for binding cannot be reused and can only be treated as waste products, resulting in a lot of waste of resources , which is not conducive to safeguarding the economic interests of power grid enterprises
