[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] like Figure 1 As shown, a specific implementation of the safety net 2 provided in this embodiment includes: a support column 1, a safety net 2, a guide rail rope 3 and a guide structure. A plurality of support columns 1 are arranged in parallel and a safety net 2 is erected on the support columns 1, the two sides of the safety net 2 have guide rail ropes 3 arranged in parallel, and the support column 1 has a guide structure for supporting the guide rail rope 3;

[0040] The guide structure comprises a support member 4 and a blocking member 5 located on one side of the support member 4. The blocking member 5 is arranged on one side of the support member 4 close to the safety net 2. The blocking member 5 has a guiding surface at least in the direction of entry toward the safety net 2. The guiding surface is an inclined surface or an arc surface. That is to say, Figure 2 As shown, when the safety net 2 is installed, the safety net 2 slides along the direction indicated by the arrow from the first end toward the second end, so as to be laid between the support columns 1 arranged in parallel, and the blocking member 5 has an inclined surface or an arc-shaped surface at least in the direction toward the first end, so that when the safety net 2 moves along the direction indicated by the arrow, the safety net 2 can flip over the blocking member 5 along the inclined surface or the arc-shaped surface.

[0041] The safety net 2 provided in this embodiment is provided with a guide structure on several parallel support columns 1, and the guide structure has a support member 4 and a blocking member 5 located on one side of the support member 4, which is used to support the guide rope 3 and prevent the guide rope 3 from falling off. By pulling the guide rope 3 on the support member 4, the safety net 2 can be moved simultaneously with the guide rope 3, thereby facilitating the installation and disassembly of the safety net 2.

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, in the safety net 2 provided in this embodiment, the safety net 2 is connected to the guide rail rope 3 by a plurality of connecting ropes 6 arranged at intervals. In this way, the safety net 2 can be connected to the guide rail rope 3, so that the safety net 2 can be driven to move simultaneously with the movement of the guide rail rope 3.

[0043] Of course, the above description is not restrictive. In some alternative embodiments, the connecting rope 6 may not be provided between the safety net 2 and the guide rail rope 3, and the guide rail rope 3 may be directly passed through the safety net 2 or other connection forms.

[0044] like Figure 1 As shown, in the safety net 2 provided in this embodiment, the angle between the connecting rope 6 and the horizontal plane is less than 45°, that is, when the safety net 2 is moved, due to the gravity of the connecting rope 6, the connecting rope 6 is tilted downward at a certain angle, and the tilt angle at this time is less than 45°. In this way, the connecting rope 6 can easily bypass the blocking member 5 to achieve the movement of the safety net 2.

[0045] Of course, the above description is not restrictive. In some alternative embodiments, the inclination angle between the connecting rope 6 and the horizontal plane may not be limited, and the connecting rope 6 can be passed around the blocking member 5.

[0046] like Figure 2 , Figure 3As shown, in the safety net 2 provided in this embodiment, the guide rail rope 3 extends out of the safety net 2 toward at least one end. In this way, one end of the guide rail rope 3 is tied to the support column 1 on one side.

[0047] Of course, the above description is not restrictive. In some alternative embodiments, the guide rail rope 3 may not extend out of the safety net 2, but may be directly tied to the safety net 2 or use other connection forms.

[0048] like Figure 2 , Figure 3 As shown, in the safety net 2 provided in this embodiment, the guide rail rope 3 extends out of the safety net 2 toward both ends. In this way, both ends of the guide rail rope 3 are simultaneously tied and connected with the support columns 1 on both sides.

[0049] Of course, the above description is not restrictive. In some alternative embodiments, the guide rail rope 3 may not extend out of the safety net 2, but may be directly tied to the safety net 2 or use other connection forms.

[0050] like Figure 4 As shown, in the safety net 2 provided in this embodiment, the blocking member 5 is circular and rotatably arranged on one side of the support member 4. In this way, when the guide rope 3 pulls the safety net 2, the rotation of the blocking member 5 can drive the connecting rope 6 to move, thereby realizing the movement of the safety net 2.

[0051] Of course, the above description is not restrictive. In some alternative embodiments, the blocking member 5 may not be configured to rotate, and the connecting rope 6 may also bypass the blocking member 5.

[0052] like Figure 4 As shown, in the safety net 2 provided in this embodiment, the support member 4 is rotatably arranged on the support column 1. In this arrangement, when the guide rope 3 moves, the support member 4 rotates under the action of the dynamic friction force of the guide rope 3, thereby moving the safety net 2.

[0053] Of course, the above description is not restrictive. In some alternative embodiments, the support member 4 may not be configured to rotate, and the guide rail rope 3 only moves by sliding.

[0054] like Figure 3 , Figure 4 As shown, in the safety net 2 provided in this embodiment, the support member 4 and the blocking member 5 are both bearings. Such an arrangement can achieve fixation with the support column 1 and realize rotation of the support member 4 and the blocking member 5 at the same time.

[0055] Of course, the above description is not restrictive, and in some alternative embodiments, the support member 4 and the blocking member 5 may also be configured as other components such as pulleys.

[0056] like Figure 1 As shown, in the safety net 2 provided in this embodiment, the support column 1 is provided with a mounting shaft 8, the support member 4 and the blocking member 5 are sequentially mounted on the mounting shaft 8, the mounting shaft 8 has an external thread, and a fastening nut 7 is mounted on the mounting shaft 8 on the outer side of the blocking member 5. In this way, the support member 4 and the blocking member 5 can be mounted on the mounting shaft 8, and the support member 4 and the blocking member 5 can be fastened.

[0057] Of course, the above description is not restrictive, and in some alternative embodiments, the mounting shaft 8 may not be provided, and other connection forms such as screw fixation may be directly adopted.

[0058] like Figure 1 As shown, in the safety net 2 provided in this embodiment, the support column 1 is a vertically arranged steel column. Such an arrangement can achieve safety protection during the installation of the steel structure.

[0059] Of course, the above description is not restrictive, and in some alternative embodiments, the support column 1 may be a support column 1 made of other materials.

[0060] Directions:

[0061] like Figure 1 , Figure 2 As shown, when the safety net 2 needs to move in the direction indicated by the arrow, first untie the guide ropes 3 tied to the steel columns on both sides, and then pull the two guide ropes 3 on one side of the moving direction at the same time. The support member 4 rotates due to the dynamic friction force, and transmits the guide rope 3 in the moving direction. The connecting rope 6 connected to the guide rope 3 goes over the blocking member 5 to drive the safety net 2 to move in the same direction; after the safety net 2 moves to the specified position, the guide ropes 3 on both sides are tied to the steel columns again, and a complete movement of the safety net 2 is completed.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
