Description

Technical Field

[0001] The utility model relates to the technical field of power transmission iron tower reinforcement, in particular to a clamping type reinforcement device for a power transmission iron tower. Background Art

[0002] Transmission towers are an essential power supply device in people's lives. When reinforcing transmission towers, traditional reinforcement tools cannot be adjusted due to the deformation of the transmission towers during use, resulting in their inability to play their original reinforcement role. Although the reinforcement device in the prior art can adjust materials of different thicknesses, the clamps are easily loosened during use due to the screw fixing method, causing the clamps to fall off, which brings inconvenience to people.

[0003] A Chinese patent discloses a reinforcement device for a transmission tower structure (authorization announcement number CN221053338U). The patent technology combines a reinforcement mechanism with a locking mechanism. The setting of the locking mechanism can not only be quickly adjusted according to the thickness of the tower body, but also can stably clamp the tower body, thereby increasing the service life of the reinforcement mechanism and thus the service life of the tower body. The overall operation is simple and fast, and there is no need to worry about falling at the positioning position.

[0004] However, it has certain disadvantages: it still needs to rotate the threaded rod to fix the tower body, but the threaded rod is easy to vibrate due to external vibrations, thereby rotating, which in turn causes the fixation to become loose. Utility Model Content
