[0002] With the continuous development of bridge construction technology, the stability and ease of installation of temporary cable trays, as an important supporting structure in the construction process, have received increasing attention. Traditional methods for fixing temporary cable tray supports typically involve welding or bolting, but these methods suffer from low installation efficiency, difficulty in adjustment, and inconvenience in disassembly. To address these issues, various adjustable locking devices have emerged on the market for connecting and fixing the supporting components of temporary cable trays. However, existing locking devices still have shortcomings in terms of adjustment accuracy, structural stability, and the reliability of the connection with the supporting components. For example, some locking devices struggle to precisely control the distance between the screws during adjustment, easily leading to loosening or detachment. Furthermore, when connecting existing devices to trusses or columns, the design of the connecting seats is often relatively simple, making it difficult to adapt to the diverse needs of different construction scenarios. In addition, the implementation of anti-detachment structures in existing technologies is limited, failing to effectively prevent the separation of critical components and affecting the overall safety of use. Therefore, developing a locking device with a reasonable structure, convenient adjustment, and reliable connection has become a current research hotspot in the field to meet the higher requirements for temporary cable tray support in bridge construction.
