[0021] Exemplarily, the connecting member 30 may be a hanging ring. Of course, the connecting member 30 may also be a rectangular frame.

[0022] Furthermore, in the present embodiment, the connecting frame 10 includes a limiting rod 11, a first vertical rod 12 and a second vertical rod 13. The first vertical rod 12 and the second vertical rod 13 are arranged opposite to each other. One end of the limiting rod 11 passes through the outer peripheral wall of the first vertical rod 12 and is connected to the outer peripheral wall of the second vertical rod 13. A first fastening screw 121 is arranged on the outer peripheral wall near the top end of the first vertical rod 12, and the first fastening screw 121 is threadedly connected to the first vertical rod 12. A second fastening screw 131 is arranged on the outer peripheral wall near the top end of the second vertical rod 13, and the second fastening screw 131 is threadedly connected to the second vertical rod 13.

[0023] by Figure 1Taking the illustrated orientation as an example, the first upright pole 12 is located on the right side, and the second upright pole 13 is located on the left side.

[0024] Specifically, the first fastening screw 121 and the second fastening screw 131 are arranged opposite to each other, and the first vertical rod 12, the limiting rod 11 and the second vertical rod 13 are sequentially connected to form a rectangular frame with an open upper end.

[0025] The center line of the connecting rod 31 is perpendicular to the center line of the limiting rod 11 .

[0026] During use, the first vertical pole 12 and the second vertical pole 13 are symmetrically clamped on both sides of the beam 3 or column, and the connecting frame 10 is fixed to the beam 3 or column by screwing the first fastening screw 121 and the second fastening screw 131, and then the safety rope is fixed to the connecting piece 30.

[0027] It should be noted that, refer to Figure 3 During use, two aerial work fixing devices 1 can also be used. The two aerial work fixing devices 1 are respectively fixed at the two ends of the same beam 3, or between two beams 3, and are connected in the middle by a steel wire rope 2 to form a safety lifeline.

[0028] Continue to refer to Figure 1 and Figure 2 In this embodiment, the tightening assembly 20 includes a connecting disk 21, a first tightening unit 22 and a second tightening unit 23. The connecting disk 21 is located in the connecting frame 10. The first tightening unit 22 is rotatably connected to the connecting disk 21. The opposite ends of the first tightening unit 22 are rotatably connected to the first vertical rod 12 and the second vertical rod 13 respectively; the second tightening unit 23 is rotatably connected to the connecting disk 21. The opposite ends of the second tightening unit 23 are rotatably connected to the first vertical rod 12 and the second vertical rod 13 respectively. The first tightening unit 22 and the second tightening unit 23 are arranged at an interval; the connecting member 30 is connected to the connecting disk 21 through a connecting rod 31.

[0029] Among them, one end of the first tightening unit 22 is rotatably connected to the first upright pole 12 through a first connecting shaft, the other end of the first tightening unit 22 is rotatably connected to the second upright pole 13 through a second connecting shaft, one end of the second tightening unit 23 is rotatably connected to the first upright pole 12 through a first rotating shaft, and the other end of the second tightening unit 23 is rotatably connected to the second upright pole 13 through a second rotating shaft.

[0030] Specifically, the center position of the first tightening unit 22 is rotatably connected to the connecting disk 21 , and the center position of the second tightening unit 23 is rotatably connected to the connecting disk 21 .

[0031] In this embodiment, the first tightening unit 22 includes a horizontal state and a tightening state. When the first tightening unit 22 is in the horizontal state, the total length of the first tightening unit 22 is the same as the total length of the limiting rod 11; when the first tightening unit 22 is in the tightening state, the first tightening unit 22 is bent; by setting that when the first tightening unit 22 is in the horizontal state, the total length of the first tightening unit 22 is the same as the total length of the limiting rod 11, it is ensured that after the connecting frame 10 is fixed on the beam 3 or the column, the first vertical rod 12 and the second vertical rod 13 are in a parallel state, and the limiting rod 11 and the first tightening unit 22 are in a parallel state.

[0032] When the first tightening unit 22 is in a horizontal state, the center line of the first vertical rod 12 is parallel to the center line of the second vertical rod 13 , and the center line of the first vertical rod 12 and the center line of the second vertical rod 13 are both perpendicular to the center line of the limiting rod 11 .

[0033] When the first tightening unit 22 is in the tightening state, the distance between the fixed end of the first vertical rod 12 and the top end of the second vertical rod 13 is reduced.

[0034] Furthermore, in the present embodiment, the first tightening unit 22 comprises a first rotating rod 221 and a second rotating rod 222, one end of the first rotating rod 221 is rotatably connected to the first vertical rod 12, the other end of the first rotating rod 221 is rotatably connected to the connecting disk 21, one end of the second rotating rod 222 is rotatably connected to the second vertical rod 13, the other end of the second rotating rod 222 is rotatably connected to the connecting disk 21, the first rotating rod 221 and the second rotating rod 222 are arranged opposite to each other, and the first rotating rod 221 and the second rotating rod 222 are arranged at an interval; when the connecting member 30 is subjected to a downward pulling force, the connecting member 30 pulls the connecting disk 21 through the connecting rod 31, so that the end of the first rotating rod 221 away from the first vertical rod 12 rotates counterclockwise, and the end of the second rotating rod 222 away from the second vertical rod 13 rotates clockwise, so that the distance between the end of the first rotating rod 221 away from the connecting disk 21 and the end of the second rotating rod 222 away from the connecting disk 21 is reduced.

[0035] Specifically, a predicted angle is arranged between the first rotating rod 221 and the second rotating rod 222 .

[0036] Furthermore, in the present embodiment, the second tightening unit 23 comprises a first connecting rod 231 and a second connecting rod 232, one end of the first connecting rod 231 is rotatably connected to the first vertical rod 12, the other end of the first connecting rod 231 is rotatably connected to the connecting disk 21, one end of the second connecting rod 232 is rotatably connected to the second vertical rod 13, the other end of the second connecting rod 232 is rotatably connected to the connecting disk 21, the first connecting rod 231 and the second connecting rod 232 are arranged opposite to each other, the first connecting rod 231 and the second connecting rod 232 are arranged at an interval, and a preset angle is clamped between the first connecting rod 231 and the second connecting rod 232; when the connecting member 30 is subjected to a downward pulling force, the connecting member 30 pulls the connecting disk 21 through the connecting rod 31, so that the end of the first connecting rod 231 away from the first vertical rod 12 rotates counterclockwise, and the end of the second connecting rod 232 away from the second vertical rod 13 rotates clockwise, so that the preset angle clamped between the first connecting rod 231 and the second connecting rod 232 increases.

[0037] By setting the limit rod 11, it can be ensured that the downward pulling force is too large at the moment of a person falling, so as to prevent the first connecting rod 231 and the second connecting rod 232 from being pulled horizontally by the instantaneous pulling force, thereby avoiding the risk of the entire aerial work fixing device 1 being pulled off.

[0038] The use process of the aerial work fixing device 1 provided in this embodiment is as follows: the first vertical pole 12 and the second vertical pole 13 are symmetrically clamped on both sides of the beam 3 or column, and the connecting frame 10 is fixed to the beam 3 or column by screwing the first fastening screw 121 and the second fastening screw 131, and then the safety rope is fixed to the connecting piece 30. When the person with the safety rope falls, the connecting piece 30 is subjected to a downward pulling force, and the connecting piece 30 pulls the connecting plate 21 through the connecting rod 31, so that the end of the first rotating rod 221 away from the first vertical rod 12 rotates counterclockwise, and the end of the second rotating rod 222 away from the second vertical rod 13 rotates clockwise, the end of the first connecting rod 231 away from the first vertical rod 12 rotates counterclockwise, and the end of the second connecting rod 232 away from the second vertical rod 13 rotates clockwise, so that the distance between the end of the first rotating rod 221 away from the connecting plate 21 and the end of the second rotating rod 222 away from the connecting plate 21 is reduced, and the preset angle clamped between the first connecting rod 231 and the second connecting rod 232 is increased, so that the open end of the connecting frame 10 is tightened, thereby increasing the friction between the first fastening screw 121 and the second fastening screw 131 and the surface of the beam 3 or the column.

[0039] The aerial work fixing device 1 provided in the present application includes a connecting frame 10, a tightening assembly 20 and a connecting piece 30; the connecting frame 10 is used to be clamped on a beam 3 or a column, the tightening assembly 20 is rotatably arranged on the connecting frame 10, the tightening assembly 20 is arranged close to the bottom end of the connecting frame 10, the tightening assembly 20 can rotate relative to the connecting frame 10, the connecting piece 30 is connected to the tightening assembly 20 through a connecting rod 31, and the connecting piece 30 is used to be connected to a safety rope; when the connecting piece 30 is subjected to a downward pulling force, the connecting piece 30 pulls the tightening assembly 20 to rotate through the connecting rod 31, so that the top end of the connecting frame 10 is tightened, thereby increasing the friction between the connecting frame 10 and the beam 3 or the column; compared with the use of a movable scaffold, the safety of the construction workers is guaranteed, and at the same time, the construction efficiency is improved.
