In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-4 As shown, the utility model provides a bridge construction anti-fall device, including a support frame 1 and a clamping assembly 2. The support frame 1 is a long rectangular frame. A winding roller 3 is arranged inside the support frame 1. Two groups of winding rollers 3 are symmetrically arranged. A protective net 4 is wound on the winding roller 3. The winding tail end of the protective net 4 is connected to a side plate 5. A slot 6 is opened on the opposite side wall of the support frame 1. Both ends of the slot 6 are hinged with a connecting rod 7. The end of the connecting rod 7 away from the support frame 1 is hinged with a connecting rod 2 8. One end of the second link 8 away from the first link 7 is hinged to the side plate 5, the first link 7 is a convex rod, and the second link 8 is a concave rod. The convex end of the first link 7 is hinged to the concave end of the second link 8. The winding roller 3 winds up the protective net 4, and controls the side plate 5 to move toward the support frame 1 through the first link 7 and the second link 8. When the protective net 4 is wound up, the side plates 5 on both sides are also blocked on both sides of the support frame 1, thereby reducing the overall volume, facilitating its storage and carrying, and improving the flexibility of the device.

[0023] like Figure 2 and 3 As shown, two groups of self-locking motors 9 are arranged, and the two groups of self-locking motors 9 are arranged corresponding to the two groups of winding rollers 3, and the output end of the self-locking motor 9 passes through the side wall of the supporting frame 1 and is connected to the corresponding winding roller 3, and the self-locking motor 9 drives the winding roller 3 to rotate and retract the protective net 4.

[0024] like Figure 1-3As shown in the figure, the clamping assembly 2 includes a clamping support plate 10, an adjusting screw 11 and an upper clamping plate 12. Anti-slip cushions are provided on the peripheries of the clamping support plate 10 and the upper clamping plate 12. The clamping support plate 10 is a U-shaped bracket. The adjusting screw 11 is threadedly fitted through the top wall of the clamping support plate 10. The upper clamping plate 12 is installed at the bottom end of the adjusting screw 11. The clamping support plate 10 is installed at the bottom of the construction bridge. By rotating the adjusting screw 11, the adjusting screw 11 drives the upper clamping plate 12 to move towards the bottom of the clamping support plate 10 under the action of screw drive, so as to clamp at the bottom support of the construction bridge.

[0025] As Figure 1-3 shown in the figure, multiple groups of clamping assemblies 2 are respectively installed on the front and rear outer walls of the support frame 1 and the outer wall of the side plate 5. When the anti-falling device needs to be used, it is convenient to perform clamping installation from multiple sides, and the stability is better.

[0026] During specific use, the clamping support plate 10 is installed at the bottom of the construction bridge. By rotating the adjusting screw 11, the adjusting screw 11 drives the upper clamping plate 12 to move towards the bottom of the clamping support plate 10 under the action of screw drive, so as to clamp at the bottom support of the construction bridge. Then, the self-locking motor 9 is started. The self-locking motor 9 drives the winding roller 3 to rotate, and the protective net 4 on the winding roller 3 is unreeled. At the same time, the side plate 5 is pulled, and through the cooperation of the first connecting rod 7 and the second connecting rod 8, the movement of the side plate 5 is adjusted, and the protective net 4 is extended to a suitable length for use. Then, the clamping assembly 2 on the side plate 5 is also clamped and fixed, and the protective net 4 provides anti-falling protection.
