Description

Technical Field

[0001] This utility model relates to the field of bridge monitoring technology, specifically to a cable force detection device for bridge engineering. Background Technology

[0002] With the advancement of science and technology, my country's infrastructure construction has entered an era of rapid development, especially in the field of bridge engineering. Cable-stayed bridges, as an important structural form of modern long-span bridges, are widely used. A cable-stayed bridge generally consists of cables, towers, and a bridge deck. Cables are typically steel cables, connected at one end to the top of the tower and at the other end to the bridge deck. The cables support the weight of the bridge deck and transfer that weight to the towers. Especially for large-scale public infrastructure structures such as cable-stayed bridges, wire-stayed bridges, and through-arch bridges, as well as large-span spatial structures like cable-stayed grid structures, monitoring their operational health is crucial because the cables support the weight of the bridge deck.

[0003] Currently, most cable tension testing machines use clamps that are directly fixed to the pulling end of the machine to hold the reinforcing bars. The inner dimensions of the clamps are matched to the dimensions of the reinforcing bars to ensure a tight grip on the ends. However, reinforcing bars come in different diameters, requiring the replacement of different clamps when testing them. This repeated disassembly and assembly is very inconvenient. Furthermore, current cable tension testing machines are relatively large, and personnel usually need to transport the reinforcing bars to a designated location for testing, making the operation cumbersome and unable to achieve on-site monitoring. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content
