With respect to the terms and units of the present invention. The term "comprises" and any variations thereof in the description and claims of this invention and the related art are intended to cover non-exclusive inclusions.

Referring to fig. 1 to 5, the protective net comprises an anti-falling net 2 and a fixed shaft 1, wherein one side of the fixed shaft 1 is connected with the anti-falling net 2, and the other side is used for being connected with a scaffold; the above-mentioned fixed shaft 1 is provided with an electromagnet 3, which electromagnet 3 is located on the side intended for connection to the scaffolding.

Through adopting this protection network, will be provided with 1 one side subsides of fixed axle of electro-magnet 3 to the scaffold frame during the use, with 1 direct absorption of fixed axle on the scaffold frame, then through other modes, fix fixed axle 1 on the scaffold frame like bolt fastening, ligature or round pin key etc. can fix a position fast like this, and is very convenient during the installation.

The electromagnet 3 is arranged in the fixed shaft 1. Compared with the electromagnet 3 externally arranged on the outer wall of the fixed shaft 1, the electromagnet 3 internally arranged in the fixed shaft 1 can better protect the electromagnet 3 and can also prevent the electromagnet 3 from interfering with the connection of other components. The stationary shaft 1 may be tubular or solid.

The fixed shaft 1 is provided with a fixed shaft screw 4, the fixed shaft screw 4 is connected with a connecting plate 6 through a spring 5, and the connecting plate 6 is fixedly connected with the anti-falling net 2. The connection plate 6 and the anti-falling net 2 can be fixedly connected by a magnetic buckle 10 and the like.

Two connecting plate screws 7 are arranged on the connecting plate 6, and the two connecting plate screws 7 are connected with the fixed shaft screws 4 through springs 5. At least two connecting plate screws 7 of the connecting plate 6 are connected with the fixed shaft screws 4, so that the orientation of the connecting plate 6 can be well kept or restored to a fixed position besides the improvement of the connection strength.

The protective net comprises two layers of anti-falling nets 2. Here at least two layers of anti-drop nets 2 to improve the safety of the structure. The upper side and the lower side of the fixed shaft 1 are provided with fixed shaft screws 4. This facilitates the arrangement of multiple layers of the anti-drop net 2.

The fixed shaft screw 4 is sleeved with a fixed rubber ring 8, one end of the spring 5 is provided with a lantern ring, the lantern ring is sleeved outside the fixed rubber ring 8, the spring 5 and the fixed shaft screw 4 can be connected more reliably through the fixed rubber ring 8, meanwhile, the excessive abrasion of the joint of the fixed shaft screw 4 and the spring 5 is prevented, and the service life of the spring 5 and the fixed shaft screw 4 is prolonged.

One side of the fixing shaft 1, which is used for being connected with a scaffold, is provided with a fixing hook 9, and the fixing hook 9 is used for being clamped with the scaffold, so that the fixing shaft is more firmly fixed with the scaffold. The fixed hook 9 comprises a fixed part 901 with an open loop structure, one end of the fixed part 901 is connected with the fixed shaft 1, the other end is hinged with a movable part 902, and the movable part 902 is folded with the fixed part 901 to enable the fixed hook 9 to form a closed loop structure. The movable portion 902 is connected to the movable portion 902 by a fastening bolt 11 at an end hinged to the fixed portion 901. The fixing hook 9 may be connected to the fixing shaft 1 by welding or bolts.

When the fixing device is used, the electromagnet 3 is electrified at first, the fixing shaft 1 is preliminarily adsorbed on the scaffold, the fixing hook 9 is lapped with the scaffold, and the bolt is screwed down, so that the structure is safer and firmer. The double-layer anti-falling net 2 is adopted, and falling objects can be received, so that the safety is improved; the spring 5 (high-strength spring 5) is used as a main link structure of the fixed shaft 1 and the anti-falling net 2, so that the shock resistance of the anti-falling safety protection device is improved, the personal safety of carelessly falling constructors can be protected, and the falling construction tools can be protected from being damaged. The arrangement of the fixed rubber ring 8 can tightly combine the spring 5 with the fixed shaft screw 4 and the connecting plate screw 7, and can also play a role in protecting the spring 5 from being damaged by pulling and rusting. The connecting plate 6 is connected with the anti-falling net 2 through the magnetic buckles 10, so that the connection between the connecting plate 6 and the anti-falling net 2 is safe, tight and convenient to detach, the anti-falling nets 2 with different lengths can be utilized in places with different requirements, and resources required by the fixing shaft 1 are saved. In areas where longer or shorter anti-fall nets 2 are required, the anti-fall nets 2 can be separated from the connecting plate 6 by simply disengaging the magnetic clasps 10 using magnets to couple other anti-fall nets 2 of a suitable length. In the process of disassembling the invention, the fixing shaft 1 and the protective net can be safely disassembled from the scaffold only by disassembling the fastening bolt 11 on the fixing hook 9 and powering off the electromagnet 3 to eliminate the magnetic force.

The protection network of this embodiment ensures the personal safety of bridge constructor strides line, prevents that construction article from dropping, influences the normal operation of below circuit. This protection network is convenient for install and dismantle, reduces the manpower consumption.

The contents of the present invention have been explained above. Those of ordinary skill in the art will be able to implement the invention based on these descriptions. Based on the above-mentioned contents of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.
