[0002] As a fundamental infrastructure, bridge engineering has been booming in recent years, with both its application scope and load-bearing capacity continuously increasing. Due to the unique nature of bridge construction locations, fall arrest devices are essential during construction. These devices not only provide better safety for personnel, preventing accidents caused by falls, but also protect against flying rocks and other materials, reducing the risk of injury to workers.

[0003] Chinese patent application number 202422427870.9 discloses a fall prevention device for long-span bridge construction, including a bridge structure, a connection and positioning mechanism, and a protective mechanism. The bridge structure has grooves along its length on both sides. The connection and positioning mechanism includes a connecting part movably installed within the groove and a positioning part fixed to the connecting part. The positioning part is located outside the groove and detachably fixedly connected to the bridge structure. The protective mechanism includes a protective part fixed to the positioning part and a snap-fit ​​part installed on the protective part. The snap-fit ​​parts are located on both sides of the protective part and are used to connect two adjacent protective parts. A buffer mechanism is located at the bottom of the protective part and fixedly connected to both the protective part and the positioning part, providing buffering for the protective part.

[0004] In actual bridge construction, the construction area varies in size. The protective width of the fall arrest device for large-span bridges is fixed and cannot be adjusted according to actual construction needs. Therefore, it is difficult to meet different protection requirements and its applicability is reduced. To address this, we propose a fall arrest safety construction device for bridges.
