[0025] See also Figures 1 to 7 , the figure shows the preferred structure of the edge protection device in this embodiment. As shown in the figure, the edge protection device includes: a frame 1, a first protection mechanism 2 and a second protection mechanism 3. Among them, the frame 1 is provided with a penetration channel 4, and the size and shape of the penetration channel 4 can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. For example: the penetration channel 4 can be circular or rectangular. When the penetration channel 4 is rectangular, the frame 1 forms a rectangular frame.

[0026] The frame 1 is used to be detachably arranged at the building entrance 5. Specifically, the frame 1 is detachably connected to the building facade 6 at the building entrance 5, so that the frame 1 is relatively fixed to the building entrance 5. Preferably, the frame 1 is connected to the building facade 6 at the building entrance 5 by bolts, which is simple to operate and easy to implement.

[0027] When the cross section of the building opening 5 is rectangular, the through passage 4 is rectangular, and the frame 1 is a rectangular frame. At this time, connecting plates 7 are provided on opposite sides of the rectangular frame. The two connecting plates 7 are arranged oppositely and parallel to each other. The two connecting plates 7 are perpendicular to the frame 1, and the two connecting plates 7 extend to the inner side of the frame 1 (that is, the inside of the building opening 5). The two connecting plates 7 correspond to the building facades 6 on both sides of the building opening 5 one by one. Each connecting plate 7 is attached to the building facade 6 on the corresponding side of the building opening 5 and connected by expansion bolts 8. Specifically, each connecting plate 7 is arranged along its height direction ( Figure 4 A plurality of openings 71 are provided in the direction from top to bottom as shown, and each opening 71 is used to pass an expansion bolt 8. The height direction of the connecting plate 7 is consistent with the height direction of the frame 1, that is, Figure 2 Preferably, the frame 1 and the two connecting plates 7 are integrally formed.

[0028] The first protection mechanism 2 is arranged in the penetration channel 4, and is used to block the staff or equipment, and the blocking is primary protection.

[0029] The second protection mechanism 3 is arranged at the penetration passage 4, and the second protection mechanism 3 is placed on one side of the first protection mechanism 2, specifically, the second protection mechanism 3 is placed outside the first protection mechanism 2, that is, the second protection mechanism 3 is placed outside the frame 1, and the outside of the frame 1 is the outside of the building opening 5. The second protection mechanism 3 is used to buffer, block and receive the staff or equipment.

[0030] It can be seen that in this embodiment, the frame 1 is placed at the building entrance 5, the first protective mechanism 2 is arranged in the through channel 4 of the frame 1 to block the staff or equipment, and the second protective mechanism 3 is placed on one side of the first protective mechanism 2. When the staff or equipment rushes out from the first protective mechanism 2, the second protective mechanism 3 can buffer and block the staff or equipment, and take over, thereby improving the protection effect, reducing the risk of falling, and solving the problem that the existing edge protection measures reduce the protection effect.

[0031] See also Figure 2 , Figure 4 , Figure 5 and Figure 7In the above embodiment, the first protective mechanism 2 includes: a plurality of guardrails 21. Among them, each guardrail 21 is arranged in parallel, and each guardrail 21 is arranged horizontally in the penetration channel 4, and each guardrail 21 is arranged at intervals in the penetration channel 4. Specifically, each guardrail 21 is arranged horizontally in the penetration channel 4. There is a preset gap between any two adjacent guardrails 21, and the preset gap can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. Each guardrail 21 is connected to the frame 1, and the connection can be a fixed connection, such as a welding connection, or a detachable connection, and this embodiment does not impose any restrictions on this. Preferably, each guardrail 21 is connected to the frame 1 by bolts.

[0032] Each guardrail 21 is arranged from the bottom to the top of the through-channel 4, and there is a preset distance between the topmost guardrail 21 and the top of the through-channel 4. Figure 4 The upper part shown) corresponds to the top of the frame 1 ( Figure 4 The upper part shown in FIG. 4 also corresponds to the top of the building opening 5. The bottom of the through passage 4 ( Figure 4 The lower part shown) corresponds to the bottom of the frame 1 ( Figure 4 The lower part shown in the figure also corresponds to the bottom of the building opening 5. The guardrails 21 are arranged in sequence from the bottom to the top of the through-passage 4. However, the guardrails 21 do not fill the entire through-passage 4, and the overall height of all the guardrails 21 is less than the height of the through-passage 4. The preset distance between the topmost guardrail 21 and the top of the through-passage 4 can be determined according to actual conditions, and this embodiment does not impose any limitation on this.

[0033] It can be seen that in this embodiment, by arranging a plurality of guardrails 21 in the penetration channel 4, each guardrail 21 provides primary protection for the staff or equipment, and can block the staff or equipment, thereby improving the protection effect.

[0034] See also Figures 1 to 7 In the above embodiments, the second protective mechanism 3 includes: a net bag 31, a roller 32 and an adjustment mechanism. Among them, two mounting plates 9 are protruding from the bottom of the frame 1. Specifically, each mounting plate 9 extends from the bottom of the frame 1 to the outside of the frame 1. The two mounting plates 9 are arranged in parallel, and there is a preset distance between the two mounting plates 9. The preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. The two mounting plates 9 are perpendicular to the frame 1. Preferably, the two mounting plates 9 are integrally formed with the frame 1. In addition, the two mounting plates 9 and the two connecting plates 7 are respectively placed on both sides of the frame 1. More preferably, the frame 1, the two connecting plates 7 and the two mounting plates 9 are all integrally formed.

[0035] The roller shaft 32 is rotatably disposed between the two mounting plates 9 so that the roller shaft 32 can rotate freely.

[0036] The adjusting mechanism is disposed on the roller shaft 32 , and is used to adjust the rotation resistance of the roller shaft 32 .

[0037] The net bag 31 has a preset flexibility and a preset strength, and the preset flexibility and the preset strength can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. One end of the net bag 31 is open, and the other parts of the net bag 31 are in a closed state, that is, the net bag 31 is in a bag shape as a whole, and the net bag 31 has only one open end 311. The open end 311 of the net bag 31 is detachably connected to the frame 1, and the open end 311 of the net bag 31 blocks the penetration channel 4, that is, the net bag 31 blocks the penetration channel 4 as a whole, so that the interior of the net bag 31 is connected to the penetration channel 4, so that the staff or equipment rushing out of the penetration channel 4 can directly fall into the net bag 31.

[0038] The bottom 312 of the net bag 31 is in a straight line shape and is wound around the roller 32. Specifically, after the opening end 311 of the net bag 31 is mounted on the frame 1, the net bag 31 is in a naturally drooping state as a whole. The bottom 312 of the net bag 31 refers to the part of the net bag 31 located at the bottom when it is in a naturally drooping state, that is, the bottom 312 of the net bag 31. The bottom 312 of the net bag 31 is in a straight line shape, which is convenient for winding around the roller 32, and the rotation of the roller 32 can wind and tighten the net bag 31. After the net bag 31 is wound around the roller 32, the adjustment mechanism adjusts the rotational resistance of the roller 32 so that the net bag 31 can remain wound around the roller 32, that is, the net bag 31 is in a stored state. However, when the staff or equipment rushes out of the guardrail 21 and falls into the net bag 31, the bottom of the net bag 31 can rotate relative to the roller 32, so that the net bag 31 is in an open state. The net bag 31 receives the staff or equipment and plays a role in buffering and blocking the staff or equipment.

[0039] Preferably, each mounting plate 9 is provided with a mounting hole 91, and the two ends of the roller shaft 32 correspond to the mounting holes 91 on the two mounting plates 9 one by one, and each end of the roller shaft 32 can be rotatably inserted into the corresponding mounting hole 91, so that the roller shaft 32 can rotate freely in the two mounting holes 91. In addition, the two ends of the roller shaft 32 are placed outside the corresponding mounting plate 9, that is, both ends of the roller shaft 32 extend out of the mounting plate 9.

[0040] The adjustment mechanism may include: an adjustment column 35 and an adjustment nut 36. The first end of the roller shaft 32 is provided with the adjustment column 35, the outer wall of the second end of the roller shaft 32 is provided with a thread, and the second end of the roller shaft 32 is screwed with the adjustment nut 36. When adjusting, the adjustment column 35 is fixed, and then the adjustment nut 36 is screwed, and the adjustment nut 36 moves toward the corresponding mounting plate 9, thereby limiting the rotation of the roller shaft 32, and realizing the adjustment of the rotation resistance of the roller shaft 32.

[0041] Preferably, a washer is sleeved on the second end of the roller shaft 32 , and the washer is clamped between the adjusting nut 36 and the corresponding mounting plate 9 .

[0042] In specific implementation, the adjustment column 35 can be an outer hexagonal column, which can be matched with a wrench, so that the wrench can be used to fix the adjustment column 35. The adjustment nut 36 can be an outer hexagonal nut, and the rotation resistance of the roller shaft 32 can be adjusted by screwing the outer hexagonal nut.

[0043] There are many ways to detachably connect the opening end 311 of the net bag 31 to the frame 1. This embodiment only introduces one of them, but is not limited to this: the second protection mechanism 3 may also include a clamping piece 33 and a plurality of clamping screws 34. The shape of the clamping piece 33 matches the shape of the frame 1. Specifically, when the frame 1 is a rectangular frame, the clamping piece 33 is also a rectangular frame structure. The clamping piece 33 is provided with a plurality of through holes 331, and each through hole 331 is arranged at intervals.

[0044] The frame body 1 is provided with a plurality of threaded holes 11 , and each threaded hole 11 corresponds to each through hole 331 one-to-one, that is, the number and position of the threaded holes 11 correspond to the number and position of the through holes 331 one-to-one.

[0045] The opening end 311 of the net bag 31 has a preset hardness, which can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. The opening end 311 of the net bag 31 is provided with a plurality of clearance holes, each of which corresponds to each through hole 331 and also corresponds to each threaded hole 11. The opening end 311 of the net bag 31 is clamped between the frame 1 and the clamping sheet 33, and each clamping screw 34 is sequentially inserted into the corresponding through hole 331, the clearance hole, and is screwed to the threaded hole 11.

[0046] In specific implementation, when the frame 1 is a rectangular frame, the opening end 311 of the net bag 31 is rectangular, and the clamping piece 33 is also a rectangular frame structure, so that the opening end 311 of the net bag 31 is clamped between the frame 1 and the clamping piece 33.

[0047] It can be seen that in this embodiment, in a normal installation state, the net bag 31 is wound on the roller 32, and the roller 32 has a certain rotation resistance. When a staff member or equipment in the building rushes out from the guardrail 21 or turns over the guardrail 21, due to the impact force, the net bag 31 expands outward, and the staff member or equipment will enter the net bag 31 and fall, and the net bag 31 can successfully catch the staff member or equipment. Since the net bag 31 is long and its bottom is wound on the roller 32 with a certain rotation resistance, when the staff member or equipment impacts the net bag 31, the net bag 31 will drive the roller 32 to rotate, and the net bag 31 will open to receive the staff member or equipment, and the net bag 31 plays a role of buffering and blocking. Since the net bag 21 has a preset strength, the net bag 31 will not break. In this way, the net bag 31 can receive falling objects and maintain ventilation and lighting. The structure of the second protective mechanism 3 is simple and easy to implement.

[0048] In summary, in this embodiment, the frame 1 is placed at the building entrance 5, the first protective mechanism 2 is arranged in the through passage 4 of the frame 1 to block the staff or equipment, and the second protective mechanism 3 is placed on one side of the first protective mechanism 2. When the staff or equipment rushes out from the first protective mechanism 2, the second protective mechanism 3 can buffer and block the staff or equipment, and take over, thereby improving the protection effect and reducing the risk of falling.
