Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of extra -high voltage iron tower installation equipment, concretely relates to a kind of extra -high voltage iron tower high-strength steel triangular iron welding fixing device. BACKGROUND

[0002] Extra-high voltage iron tower is a high-rise structure for supporting extra-high voltage transmission line. Extra-high voltage transmission is a kind of efficient long-distance power transmission mode, and the voltage level is 1000 kV or above for alternating current or ±800 kV or above for direct current. The main function of the iron tower is to erect the transmission conductor at a certain height from the ground to avoid contact between the conductor and the ground objects, ensuring the safe and stable transmission of electric energy. Extra-high voltage iron tower is mainly made of steel. Because steel has high strength and good toughness, it can withstand large tensile force, pressure and bending force, etc. For example, commonly used Q345 and Q420 steel has high yield strength, which can ensure the structural stability of the iron tower under various complex load conditions (such as strong wind, icing, etc.). At the same time, steel also has the characteristics of good processability, which is convenient for manufacturing iron tower components of various shapes and specifications.

[0003] Extra-high voltage iron tower has a huge volume. The installation of iron tower components needs to be strictly in accordance with the design requirements to ensure the tight connection of components and the integrity of the overall structure of the iron tower. At the same time, the construction personnel need to consider the direction of the line, the topography, the surrounding environment and many other factors to adjust the connection mode of the components in local position. For the adjustment of these local components, the method of air welding is usually used for adjustment and fixation.

[0004] The size of the components of extra-high voltage iron tower is large. During air welding, it is difficult for a person to fix the component position while welding the component. Therefore, it is usually done by one person holding and fixing and the other person welding. During high-altitude operation, two people working close together are dangerous, so it is better to complete the air welding operation by one person.

[0005] In order to enable the operator to complete the air welding by one person in the high altitude, the utility model hopes to provide a kind of extra -high voltage iron tower high-strength steel triangular iron welding fixing device. CONTENT OF UTILITY MODEL
