Description

Technical Field

[0001] The utility model relates to the technical field of iron tower anti-deformation structures, in particular to a load-resistant deformation steel structure of a high-low leg power transmission iron tower. Background Art

[0002] With the rapid development of the power industry, the safety, stability and economy of transmission towers, as the key supporting structure of the power system, have received increasing attention. Traditional transmission tower designs mostly adopt a unified structure, but under complex terrain and climatic conditions, this design is often difficult to meet actual needs. Especially in mountainous and hilly terrains, due to the difference in ground elevation, transmission towers need to adapt to different ground heights to ensure the stable suspension of transmission lines.

[0003] In order to adapt to the height difference of different ground, high and low leg transmission towers that can adapt to different terrain conditions and have excellent anti-deformation ability are developed. However, in actual use, due to the large terrain difference, the high and low leg towers may be installed in the process of bearing and installation. Due to uneven force or soil erosion, the overall load intensity of the transmission tower is increased, which may cause the transmission tower to deform and twist, and then tilt or collapse accidents. The overall anti-deformation bearing capacity is insufficient, and the safety hazard is relatively large. For this reason, we propose a high and low leg transmission tower load-resistant deformation steel structure to solve the above problems. Utility Model Content

The combination is a whole, and the integration increases the bearing strength. A tensile axis 8 is provided in the middle of the anti-deformation mounting frame 7, and the evenly distributed tensile inclined steel cables 9 play a tensile and anti-deformation role on the tower. The overall anti-deformation bearing capacity is strong, the structure is safe and stable, so that the device has the ability to resist deformation and load, the overall tensile strength of the tower body is relatively high, and the anti-deformation safety bearing performance is high.

[0031] Furthermore, the anti-deformation mounting frame 7 is cross-bolted to the tower support lower leg 3 and the tower support high leg 4, and the four ends of the top of the anti-deformation mounting frame 7 are provided with anti-deformation reinforcement rods 10, and the top ends of the four anti-deformation reinforcement rods 10 are respectively bolted to the tower support lower leg 3 and the tower support high leg 4;

[0032] The anti-deformation mounting frame 7 is cross-bolted to the tower support lower leg 3 and the tower support high leg 4, so that they are combined into a horizontal whole with good integrity.

Those skilled in the art can easily implement it. It belongs to the existing technology and will not be elaborated.

[0046] Working principle: By setting the legs of the transmission tower as the tower bearing low leg 3 and the tower bearing high leg 4, they are bolted to the low leg tower base 1 and the high leg tower base 2 respectively, and are respectively arranged above and below the terrain, the transmission tower can be stably installed under terrain conditions with high and low drop.

[0047] An anti-deformation mounting frame 7 is provided between the tower bearing lower leg 3 and the tower bearing high leg 4, which are cross-shaped and stably connected to form a horizontal whole with good integrity. A tensile axis 8 is provided in the middle of the anti-deformation mounting frame 7, and a plurality of groups of tensile inclined steel cables 9 are provided at both ends of the tensile axis 8, which play a role of anti-tensile bearing on the tower bearing lower leg 3 and the tower bearing high leg 4, and cooperate with the anti-deformation of the anti-deformation mounting frame 7 to play a role of anti-tensile deformation resistance. The overall anti-deformation bearing capacity is strong, and it is not easy to cause the overall deformation of the tower due to high load caused by terrain changes. The structure is safe and stable, so that the device has the ability to resist deformation and load resistance. The overall tensile strength of the tower body is high, and the anti-deformation safety bearing performance is high, which solves the problem that the existing high and low leg transmission towers may be deformed and twisted due to uneven force or soil erosion, and the problem of insufficient anti-deformation bearing capacity.
