[0033] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0034] Example: Figures 1 to 11 As shown, a safety protection device for high-altitude operations in building structures with H-shaped steel beams includes a top main board 1, a left clamping assembly 4 and a right clamping assembly 5. The top main board 1 is set on the upper end surface of the upper side flange plate of the H-shaped steel beam 6. The top main board 1 is provided with a vertical pole 2, and several lifeline threading coils 3 are arranged at intervals on the vertical pole 2.

[0035] The left clamping assembly 4 includes a clamping arm 13, a jaw 11, and a guide post 12. The clamping arm 13 includes a first connecting part 15 and a second connecting part 16. The second connecting part 16 is connected to the top main plate 1. The first connecting part 15 extends to the left and protrudes from the left side of the H-shaped steel beam 6. The right end of the second connecting part 16 is provided with a safety net fastening hole 18, which protrudes from the right side of the top main plate 1 and the H-shaped steel beam 6. The lower part of the first connecting part 15... A limiting protrusion 14 is provided on the right side of the end face. The limiting protrusion 14 abuts against the left end of the upper flange plate of the H-beam 6 and limits it. The upper end of the guide post 12 is connected to the left side of the first connecting part 15. The clamping bolt 9 passes downward through the middle of the first connecting part 15 and is threaded with the middle of the jaw 11. The left end of the jaw 11 slides along the guide post 12. When the clamping bolt 9 is tightened, the right end of the jaw 11 moves away from or is pressed against the lower end face of the upper flange plate of the H-beam 6.

[0036] The right clamping component 5 has the same structure as the left clamping component 4 and is symmetrical. The first connecting part 15 of the right clamping component 5 extends to the right and protrudes from the right side of the H-beam 6. The limiting protrusion 14 of the right clamping component 5 abuts against the right end of the upper flange plate of the H-beam 6 for limitation. The safety flat net tethering hole 18 of the right clamping component 5 protrudes from the left side of the top main plate 1 and the H-beam 6. When the clamping bolt 9 of the right clamping component 5 is tightened, the left end of the claw 11 of the right clamping component 5 moves away from or clamps the lower end surface of the upper flange plate of the H-beam 6.

[0037] Two limiting protrusions 14 abut against the two sides of the upper flange plate of the H-beam 6, and the top main plate 1 abuts against the upper end face of the upper flange plate of the H-beam 6. By tightening the two clamping bolts 9, the two clamping claws 11 can clamp the upper flange plate of the H-beam 6, thus realizing the fixation of the H-beam 6 by this utility model. The clamping of the clamping claws 11 can adapt to H-beams with flange plates of different thicknesses. The upright 2 is firmly welded and fixed to the top main plate 1. The lifeline threading coil 3 can be used to thread the lifeline. The right end of the left clamping component 4 and the left end of the right clamping component 5 are provided with safety flat net tethering holes 18. Through the cooperation of multiple structural components, the arrangement of safety flat nets on the entire construction work surface can be realized.

[0038] The top main plate 1 has two through-slots 21. The second connecting part 16 is a long strip-shaped structure. The second connecting parts 16 of the left clamping assembly 4 and the right clamping assembly 5 slide in a one-to-one correspondence with the two slots 21. Several adjusting screw holes 17 are arranged at intervals along the length of the second connecting part 16. The top main plate 1 has two fixing holes 19. One fixing hole 19 is bolted to any adjusting screw hole 17 on one of the second connecting parts 16, and the other fixing hole 19 is bolted to any adjusting screw hole 17 on another of the second connecting parts 16. By changing the adjusting screw holes 17 connected to the fixing holes 19, the distance between the two grippers 11 can be adjusted to accommodate H-beams 6 with different flange widths.

[0039] The top main plate 1 has two observation holes 20, which correspond one-to-one with two fixing holes 19. The observation holes 20 are located on the side of the fixing holes 19 facing the safety net fastening holes 18. The distance between the observation holes 20 and the fixing holes 19 is set according to the distance between two adjacent adjusting screw holes 17. The observation holes 20 are used to observe whether the position of the adjusting screw holes 17 is aligned.

[0040] The guide post 12 is a cylindrical component. One end of the gripper 11 is provided with an adapter hole 24, and the middle part of the gripper 11 is provided with a clamping screw hole 25. The lower end of the clamping bolt 9 is threaded into the clamping screw hole 25. The adapter hole 24 is axially slidingly engaged with the guide post 12 and circumferentially rotating. The first connecting part 15 is provided with an elongated arc hole 23 with one end open. The elongated arc hole 23 is coaxial with the corresponding guide post 12, and the radius of the elongated arc hole 23 is set according to the hole spacing of the adapter hole 24 and the clamping screw hole 25. When the gripper 11 is rotated, the cap end of the clamping bolt 9 rotates into or out of the corresponding elongated arc hole 23. With this configuration, before connecting the present invention to the H-beam 6, the two clamping jaws 11 can be rotated so that the opposite ends of the two clamping jaws 11 are far apart, making it easier for the two clamping jaws 11 to fall from both sides of the upper flange plate of the H-beam 6. When the top plate 1 is in contact with the upper flange plate of the H-beam 6, the two clamping jaws 11 can be rotated again so that the clamping bolts 9 are turned into the corresponding elongated arc holes 23. One end of the two clamping jaws 11 is rotated to the lower part of the upper flange plate of the H-beam 6. Tightening the clamping bolts 9 will allow the clamping jaws 11 to quickly clamp the upper flange plate of the H-beam 6.

[0041] The first connecting part 15 is provided with a column hole 22, and the guide post 12 passes through the column hole 22 upward and is connected to the upper baffle 8. The guide post 12 and the first connecting part 15 are configured as a rotatable connection structure, which facilitates the operation on the upper side of the protective device to rotate the corresponding gripper 11.

[0042] The upright 2 and the top main board 1 are connected by several triangular reinforcing plates 7.

[0043] By dividing several lifeline coils 3 into groups of two, and setting several groups of lifeline coils 3 vertically spaced 600mm apart, it is possible to arrange upper and lower layers of lifelines across the entire construction work surface.

[0044] The slide 21 is an inverted trapezoidal slide 21, and the cross-sectional profile of the second connecting part 16 is adapted to the cross-sectional profile of the slide 21.

[0045] The lower end of the guide post 12 is detachably connected to a lower end baffle 10. The outline of the lower end baffle 10 is larger than the diameter of the adapter hole 24. This design can prevent the gripper 11 from falling off.

[0046] The above embodiments are merely illustrative examples of the present utility model and do not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present utility model, they are all within the scope of protection of the present utility model.
