Description

Technical Field

[0001] The utility model relates to the technical field of angle steel towers, in particular to an installation-free welding reinforced angle steel tower for power transmission. Background Art

[0002] A transmission tower is a support point for an overhead line. Installing one circuit on a transmission tower is a single-circuit transmission tower, and installing two circuits on a transmission tower is a double-circuit transmission tower. A single circuit means a circuit where a load has one power supply; a double circuit means a circuit where a load has two power supplies. Generally, enterprises with high requirements for power supply reliability or important substations in a region adopt double-circuit power supply, so that in case one power supply fails, the other power supply can continue to supply power. However, for general small and medium-sized users with low requirements for power supply reliability, single-power supply is often adopted.

[0003] Currently, when the existing angle steel towers are affected by strong winds, they are prone to shaking and collapse. However, the existing reinforcement structures generally require welding operations. Since the angle steel towers are relatively tall, it is difficult to carry welding equipment up, and there are also certain risks in welding at high altitudes. Therefore, an installation-free welding reinforced angle steel tower for power transmission is provided (specifically refer to the patent number: 202020497393.2), which includes a tower base, a tower body installed on the upper part of the tower base, and a tower tip installed on the upper part of the tower body. Tower arms a and tower arms b are provided on both sides of the tower tip, and at least four support components are connected between the tower arms a and tower arms b; it can effectively improve the wind resistance strength of the tower arms a and tower arms b, ensure the overall stability and improve the overall strength. At the same time, common bolt installation is adopted, eliminating the need for high-altitude welding operations, reducing the risk of high-altitude operations and improving the installation efficiency. The support components are used to support the tower arms b by the tower arms a, ensuring the stability of the tower arms b. At the same time, the force received by the tower arms a will be evenly dispersed to the tower body through the connecting steel frame. Compared with traditional angle steel towers, the device has stronger bearing capacity, better stability, is not prone to collapse, and has a high safety factor.

[0004] However, currently, most of the existing angle steel towers for power transmission adopt welding technology for installation and fixation, which not only increases the installation and fixation time of the device, but sometimes it is impossible to perform welding fixation in all directions, affecting the connection firmness and causing accidents. At the same time, some angle steel towers for power transmission are large in size, resulting in inconvenient full-time transportation work and poor practicability. Summary of the Utility Model
