[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: an I-beam column lifeline anti-fall device, comprising an I-beam column 1, a high-strength L-shaped metal sheet 2, a high-strength inner screw barrel 12, a spring push plate 8 and a welding plate 3, wherein two high-strength L-shaped metal sheets 2 are provided, and the two high-strength L-shaped metal sheets 2 are symmetrically attached to the front and rear positions of the I-beam column 1, and two welding plates 3 are provided, and the two welding plates 3 are respectively welded to the left ends of the inner sides of the two high-strength L-shaped metal sheets 2, and the side surfaces of the two welding plates 3 are screwed with reinforcing bolts 4 through threads, and the right ends of the two reinforcing bolts 4 are longitudinally fixed with anti-slip clips 5, and the two high-strength L-shaped metal sheets 2 are provided with Anti-skid groove 6, multiple return springs 7 are installed in the two anti-skid grooves 6, two spring push plates 8 are longitudinally installed on the inner side of the multiple return springs 7, and anti-skid push plates 9 are fixed on the inner side of the two spring push plates 8. The second high-strength threaded rod 14 is fixed at the upper and lower positions of the right end of the front high-strength L-shaped metal sheet 2, and the first high-strength threaded rod 13 is fixed at the upper and lower positions of the right end of the rear high-strength L-shaped metal sheet 2. Two high-strength inner screw barrels 12 are provided. This design solves the problem that part of the lifeline is to fix the support with a steel pipe on the steel beam by multiple bolts, but it takes a lot of time to tighten the bolts during installation, and the work efficiency is low.

[0020] As the first embodiment of the utility model: the right ends of the two anti-skid clips 5 are tightly against the right side of the inside of the I-beam column 1. By adding two anti-skid clips 5 tightly against the right side of the inside of the I-beam column 1, the I-beam column 1 can be tightly attached to the two high-strength L-shaped metal sheets 2. Two anti-skid push plates 9 are tightly against the right sides of the front and rear ends of the I-beam column 1 respectively, and the multiple reset springs 7 are all in a semi-compressed state. The added multiple reset springs 7 can push the two anti-skid push plates 9 to tightly against the front and rear ends of the I-beam column 1 through the two spring push plates 8.

[0021] The front ends of the two high-strength inner screw barrels 12 are screwed into the two second high-strength threaded rods 14 through threads, and the rear ends of the two high-strength inner screw barrels 12 are screwed into the two first high-strength threaded rods 13 through threads. The front ends of the two high-strength inner screw barrels 12 are left-handed threads, and the rear ends of the two high-strength inner screw barrels 12 are right-handed threads. The two second high-strength threaded rods 14 are both left-handed threads, and the two first high-strength threaded rods 13 are both right-handed threads. By adding the two high-strength inner screw barrels 12 with left-handed threads as the front ends, and right-handed threads as the rear ends, the two second high-strength threaded rods 14 are both left-handed threads, and the two first high-strength threaded rods 13 are both right-handed threads, when the two first high-strength threaded rods 13 rotate, the two first high-strength threaded rods 13 and the second high-strength threaded rods 14 can be mobilized to move toward each other or in opposite directions, thereby driving the two high-strength L-shaped metal sheets 2 to move toward each other or in opposite directions. The right ends of the two high-strength L-shaped metal sheets 2 are welded with welding sheets 10, and the right ends of the two welding sheets 10 are provided with safety lifelines 11, and the safety lifelines 11 are made of galvanized steel wire ropes. The added safety lifelines 11 facilitate the hanging of safety belts.

[0022] As the second embodiment of the utility model: when the device needs to be installed and used, the two high-strength L-shaped metal sheets 2 are put on the right side of the I-beam column 1, and then the two reinforcing bolts 4 are tightened with an external wrench, so that the two anti-slip clips 5 are tightly against the right side of the inside of the I-beam column 1, so that the I-beam column 1 and the two high-strength L-shaped metal sheets 2 can be fixed together, and then the two high-strength inner screw barrels 12 are tightened in the same direction and at the same speed with an external wrench. Since the two first high-strength threaded rods 13 and the two second high-strength threaded rods 14 have opposite thread rotation directions, the two first high-strength threaded rods 13 and the two second high-strength threaded rods 14 can be moved toward each other until the two anti-slip push plates 9 are fixed to the right side of the front and rear ends of the I-beam column 1, and the multiple reset springs 7 are forced to be in a semi-compressed state, so that the two high-strength L-shaped metal sheets 2 can be installed and fixed, so that the safety belt can be hung at the safety lifeline 11 later.
