[0029] Specifically, after the guardrail assembly 3 is installed at the opening 2 of the factory floor slab 1, the guardrail assembly 3 is in a state of isolating the opening 2, reducing the actual size of the guardrail to be built at the opening 2. During the process of pulling the two side guardrails 4, the guardrails 4 can be horizontally connected with the guide assembly 5 for quickly building the two side walls of the guardrail assembly 3. The two sets of guardrails 4 can also form a stable force support point with the guardrail assembly 3, so that the guardrail assembly 3 and the guardrails 4 on both sides are in an all-round anti-deformation structure.

[0030] The guardrail assembly 3 includes a main beam plate 31; for example, such as Figure 3 and Figure 4 As shown.

[0031] Positioning plates 32 are fixedly connected to both sides of the outer wall of the main beam plate 31 near the bottom. Both sets of positioning plates 32 have through holes, and bolts are installed in the through holes. One end of the bolts is fastened to the top of the factory floor slab 1. Several sets of internal threaded holes 33 are opened at the bottom of the main beam plate 31. The several sets of internal threaded holes 33 are equally spaced from the central axis of the main beam plate 31. Two sets of guide rollers 34 are attached to the bottom of the main beam plate 31, and screws for fastening to the internal threaded holes 33 are connected through the two sets of guide rollers 34.

Then push the protective plates 4 on both sides so that the insertion grooves 6 fit into the ends of the movable baffles 36 to quickly form a rectangular protective railing.

[0039] The working principle of the quick-assembly and disassembly protective railing device for factory construction edge openings proposed in this embodiment is as follows:

[0040] By using the two sets of guide rollers 34 at the bottom of the main beam plate 31, the main beam plate 31 can be horizontally rolled and attached to the top of the factory floor slab 1. At the same time, the main beam plate 31 can be transported to the position of the opening 2 by a single person. The main beam plate 31 is pushed horizontally so that the two sets of guide rollers 34 can be engaged with the two sides of the inner wall of the opening 2. Before the positioning plate 32 is installed with bolts, the main beam plate 31 can also stand upright on the top of the opening 2, reducing the installation difficulty for construction personnel.

[0041] After the two sets of positioning plates 32 are bolted to the top of the factory floor slab 1, the connection angle between the right angle rod 51 and the guide rod 55 is adjusted by the cooperation of the first hinge seat 52, the second hinge seat 53 and the linkage rod 54, so that the protective plates 4 on both sides can approach the limiting block 56 during the horizontal sliding connection on the guide rod 55, forming the two side walls of the guardrail.

[0042] By pulling the movable baffles 36 in the embedded grooves 35 on both sides, the movable baffles 36 are extended to both sides of the main beam plate 31 in a double-door manner to fill the connection between the main beam plate 31 and the protective plates 4 on both sides. Then, the protective plates 4 on both sides are pushed so that the insertion grooves 6 are fitted onto the ends of the movable baffles 36 to quickly form a rectangular protective railing.
