DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0019] As Figures 1-3 shown, a portable gate detection safety guardrail provided by an embodiment of the present utility model includes a first vertical frame 1 and a second vertical frame 2. A scissor mechanism 4 is hinged between the first vertical frame 1 and the second vertical frame 2. A protective net 7 is arranged on one side of the scissor mechanism 4. A main beam rear flange 5 is arranged on one side of the first vertical frame 1 and the second vertical frame 2. A connecting mechanism 3 adapted to the main beam rear flange 5 is arranged at the bottoms of the first vertical frame 1 and the second vertical frame 2. Both the first vertical frame 1 and the second vertical frame 2 include vertical rods 8. Cross bars 6 are welded to the bottoms of the vertical rods 8. Both ends of the protective net 7 are fixed to the two cross bars 6 respectively.

[0020] Specifically, in this embodiment, it includes a first vertical frame 1 and a second vertical frame 2. The first vertical frame 1 and the second vertical frame 2 are symmetrically arranged. A scissor mechanism 4 is hinged between the first vertical frame 1 and the second vertical frame 2. The scissor mechanism 4 can be telescoped. A protective net 7 is arranged on one side of the scissor mechanism 4. The protective net 7 is perpendicular to the plane where the scissor mechanism 4 is located. A main beam rear flange 5 is arranged on one side of the first vertical frame 1 and the second vertical frame 2. The main beam rear flange 5 is a partial structure of the main beam of the gate. A connecting mechanism 3 adapted to the main beam rear flange 5 is arranged at the bottoms of the first vertical frame 1 and the second vertical frame 2. The connecting mechanism 3 plays a role in connecting the first vertical frame 1 and the second vertical frame 2 to the main beam rear flange 5, preventing the first vertical frame 1 and the second vertical frame 2 from detaching from the main beam rear flange 5. Both the first vertical frame 1 and the second vertical frame 2 include vertical rods 8. Cross bars 6 are welded to the bottoms of the vertical rods 8. The arrangement of the cross bars 6 makes it so that the vertical rods 8 do not easily interfere with the cross bars 6 during the activities of the staff due to the widened distance between the main beams. Both ends of the protective net 7 are fixed to the two cross bars 6 respectively. The cross bars 6 on the first vertical frame 1 and the second vertical frame 2 play a role in fixing the protective net 7.

[0021] A portable gate detection safety guardrail provided by the present utility model is connected to the main beam rear flange 5 through the connecting mechanism 3, so that the scissor mechanism 4 and the protective net 7 between the first vertical frame 1 and the second vertical frame 2 can play a protective role for the staff, thereby making the staff safer when detecting the gate. At the same time, the scissor mechanism 4 between the first vertical frame 1 and the second vertical frame 2 can be folded, reducing the overall occupied volume, and thus facilitating the staff to carry.

[0022] In another embodiment provided by the present utility model, a second sliding sleeve 17 is sleeved outside the vertical rod 8. The second sliding sleeve 17 can move outside the vertical rod 8. The free end of the scissors mechanism 4 is hinged to the second sliding sleeve 17, making the scissors mechanism 4 more stable when unfolding or folding, and making the connection between the scissors mechanism 4 and the vertical rod 8 more firm. One outer wall of the second sliding sleeve 17 is threadedly connected with a second locking bolt 18. By slidingly connecting the second sliding sleeve 17 with the vertical rod 8 and fixing the second sliding sleeve 17 to the vertical rod 8 through the second locking bolt 18, the scissors mechanism 4 can be fixed after unfolding, so that the protective net 7 can maintain the unfolded state, making the safety guardrail more reliable when in use.

[0023] In another embodiment provided by the present utility model, the connecting mechanism 3 includes a bottom rod 9. The top end of the bottom rod 9 is welded to the cross bar 6. The bottom rod 9 is located at one end of the cross bar 6 away from the vertical rod 8 and is below the vertical rod 8. A fixed stop rod 15 is welded to the bottom end of the bottom rod 9; a first sliding sleeve 10 is sleeved outside the bottom rod 9. A movable stop rod 13 is welded to one outer wall of the first sliding sleeve 10; a nut 11 is welded to one outer wall of the first sliding sleeve 10, and a first locking bolt 12 is threadedly connected inside the nut 11. By providing the fixed stop rod 15, the movable stop rod 13 and the first locking bolt 12, the rear flange 5 of the main beam is clamped by the fixed stop rod 15 and the movable stop rod 13, and then the fixed stop rod 15 is fixed by the first locking bolt 12. There is no need to drill holes in the rear flange 5 of the main beam, nor to damage the structure of the rear flange 5 of the main beam, making it more convenient to connect the safety guardrail to the rear flange 5 of the main beam; a first roller 14 is rotatably connected to one outer wall of the fixed stop rod 15 close to the bottom rod 9, and a second roller 16 is rotatably connected to one outer wall of the movable stop rod close to the bottom rod 9. The first roller 14 and the second roller 16 make it smoother to move the safety guardrail on the rear flange 5 of the main beam.

[0024] Working principle: When in use, first place the rear flange 5 of the main beam between the movable stop rod 13 and the fixed stop rod 15, then drive the movable stop rod 13 to move downward through the first sliding sleeve 10, making the movable stop rod 13 and the fixed stop rod 15 approach each other, and then fix the first sliding sleeve 10 to the bottom rod 9 through the first locking bolt 12. Then pull the first upright 1 and the second upright 2 apart to fully unfold the protective net 7. At this time, the scissors mechanism 4 also unfolds. Then fix the second sliding sleeve 17 to the vertical rod 8 through the second locking bolt 18 to fix the distance between the first upright 1 and the second upright 2. At this time, the staff can stand on the rear flange 5 of the main beam to detect and maintain the gate, making the scissors mechanism 4 and the protective net 7 play a protective role for the staff, thus effectively ensuring the safety of the staff.

[0025] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
