Description

Technical Field

[0001] The utility model relates to the technical field of bridge cable tension monitoring, in particular to a bridge cable tension monitoring device. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient.

[0003] Among them, cable-stayed bridges are an important structural form of modern large-span bridges and are widely used in the field of bridge engineering. In the prior art, cable-stayed bridges generally include cables, bridge towers and bridge decks. The cables are generally steel cables, one end of which is connected to the top of the bridge tower and the other end is connected to the bridge deck. The cables support the weight of the bridge deck and transfer the weight to the bridge tower. Since the cables support the weight of the bridge deck, bridge cables are important bridge material components mainly used to bear the tension of some structures in bridge engineering. They are an important factor in ensuring the load-bearing capacity of bridges. Qualified bridge cables must be able to withstand strong traction. Therefore, when producing bridge cables, it is necessary to test the cable force that the cables can withstand.

[0004] The bridge cable tension monitoring device refers to a device for measuring the stress on the bridge cables. Because the cables are the main load-bearing components that directly transfer the weight of the main beam and bridge deck of the cable-stayed bridge to the tower, monitoring their stress status is essential. However, when using existing bridge cable tension monitoring equipment, the adaptation size of the equipment is constant and can only be used for cables of specific sizes. In addition, the tension measurement range is fixed and the tension range cannot be adjusted, which affects the use effect and performance. Utility Model Content
