[0023] Refer to the figure, Figure 2 and Figure 3 As shown, a safety anti-fall device for bridge construction in road and bridge construction comprises an anti-fall frame 1, embedded frames 2 are arranged at both ends of the anti-fall frame 1, the embedded frames 2 are fixedly connected to the anti-fall frame 1 by bolts, an anti-fall steel net 3 is installed in the anti-fall frame 1, the four sides of the anti-fall steel net 3 are fixedly connected to the anti-fall frame 1, a top frame 4 is arranged on the upper end surface of the anti-fall frame 1, a rope net 5 is arranged in the top frame 4, and the rope net 5 is fixedly connected to the top frame 4 on all sides. By arranging embedded frames 2 at both ends of the anti-fall frame 1, it is only necessary to install the anti-fall frame 1 on the embedded frames 2 at both ends for stable use during installation. When disassembly is required, it can also be directly disassembled from the embedded frames 2, which is very convenient for assembly and disassembly. At the same time, by fixedly installing the anti-fall steel net 3 in the anti-fall frame 1, it is convenient to use the anti-fall steel net 3 as the anti-fall net bag at the bottom. By arranging a top frame 4 on the upper end surface of the anti-fall frame 1 and installing a rope net 5 in the top frame 4, it is ensured that the rope net 5 is stably arranged directly above the anti-fall steel net 3, and the rope net 5 is used as the anti-fall net bag at the top. In this way, when objects fall from the upper end, they can be first cached and received by the rope net 5, and then received for the second time by the anti-fall steel net 3 at the lower end, thereby increasing the safety and anti-fall effect during construction.
[0024] Reference Figure 2 and Figure 4As shown, the anti-fall frame 1 is a frame-shaped structure composed of two side plates 11 and two cross bars 12, and connection holes 111 are opened at both ends of the side plates 11. The anti-fall frame 1 structure is formed by the two side plates 11 and the two cross bars 12, which is convenient for stably installing the anti-fall steel net 3 through the anti-fall frame 1, and the connection holes 111 are set to facilitate the connection and fixation with the embedded frame 2 and the top frame 4.

A second matching hole 421 corresponding to the connection hole 111 is provided on the right-angle seat 42. The structural setting of the top frame 4 ensures that the main frame body 41 can be stably installed on the upper end surface of the anti-fall frame 1 through the right-angle seats 42 on the four corners, and at the same time, the second matching holes 421 are arranged to facilitate the connection and fixing with the anti-fall frame 1 by bolts.
[0027] Working principle: During the actual installation, the anti-fall frame can be directly placed on the pre-embedded frame, and then the top frame can be placed on the upper end surface of the anti-fall frame through the right-angle seat. After the connecting hole, the first matching hole and the second matching hole are aligned with each other, the three can be fixed to each other through bolts. In this way, the purpose of double protection can be achieved through the rope net and the anti-fall steel net, and when not in use, you only need to remove the bolts to remove the embedded frame and the top frame.
