Detailed implementation mode

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] Embodiment 1

[0029] As Figures 1-4 shown, a safety net includes a vehicle body 1 and a winding shaft 2 vertically and rotatably connected to the vehicle body 1. A safety net 3 is wound around the winding shaft 2. Limit strips 4 are installed at both the upper and lower ends of the safety net 3 along the length direction of the safety net 3. At least one support rod 5 (the number of support rods 5 is two in this embodiment) is installed on the safety net 3. Two limit bayonets 6 for the two limit strips 4 to move therein are installed on the support rod 5. Walking wheels 7 for walking are installed at the bottom of the vehicle body 1, and the walking wheels 7 are in transmission connection with the winding shaft 2;

[0030] In this embodiment, the number of walking wheels 7 is four and they are distributed in a rectangle. A coaxial first bevel gear 8 is installed on one of the walking wheels 7, and a coaxial second bevel gear 9 is installed at the bottom of the winding shaft 2. The first bevel gear 8 and the second bevel gear 9 are meshed, and the rotation of the walking wheels 7 drives the winding shaft 2 to wind, without manual rotation of the winding shaft 2 for winding and without external force drive; in this embodiment, the two coaxial walking wheels 7 are connected, and the first bevel gear 8 is installed on the shaft of one of the walking wheels 7;

[0031] In order to facilitate the storage of the support rod 5, a U-shaped storage rack is vertically installed on the vehicle body 1. The winding shaft 2 is located inside the storage rack. A partition rod 10 is installed on one side of the opening of the storage rack. An L-shaped placement rack 11 is installed outside the side of the storage rack where the partition rod 10 is installed. The placement rack 11 is L-shaped in top view and is fixedly connected to the storage rack. The placement rack 11 is used to place the support rod 5; the partition rod 10 is used to extend between the safety net 3 and the support rod 5 to separate the middle parts of the two. The setting of the partition rod 10 can facilitate the winding of the safety net 3 around the winding shaft 2 and the support rod 5 located in the placement rack 11. The partition rod 10 can prevent the support rod 5 from being wound around the winding shaft 2 along with the safety net 3 during the winding process;

[0032] In this embodiment, the length direction of the partition rod 10 is parallel to that of the limiting strip 4, and the partition rod 10 is located between the two limiting strips 4.

[0033] Working principle: When the staff needs to use the enclosure net 3 for enclosure, first place the support rod 5 far from the winding shaft 2 on the ground, and then move the vehicle body 1. During the movement of the vehicle body 1, the traveling wheels 7 rotate synchronously to make the winding shaft 2 release the wound enclosure net 3. According to the interval requirements of the support rods 5, place the next support rod 5 on the ground after the vehicle body 1 moves to a certain position, and so on. The setting of the limiting strip 4 can enable the support rod 5 to effectively support the enclosure net 3, and the vehicle body 1 serves as the final support; when collecting the enclosure net 3, by pushing the vehicle body 1 back, the traveling wheels 7 rotate to drive the winding shaft 2 to rotate to wind up the enclosure net 3. When the vehicle body 1 moves to one side of the support rod 5, the staff takes the support rod 5 off the ground and puts it into the placement rack 11, and continues to push the vehicle body 1 to move to the next support rod 5, and so on, to complete the winding of the enclosure net 3.

[0034] Combined with the above, the present application completes the retraction and deployment of the safety enclosure net 3 through the settings of the vehicle body 1, the winding shaft 2, the enclosure net 3, the limiting strip 4 and the support rod 5, without the need for the staff to transport separately and place them one by one, improving the placement and retraction efficiency of the safety enclosure net 3 and effectively solving the problem of low retraction and deployment efficiency of the current safety enclosure net 3.

[0035] Embodiment 2

[0036] As Figure 1 、 Figure 2 and Figure 4 shown, the structure of this embodiment is substantially the same as that of Embodiment 1. This embodiment is further optimized on the basis of Embodiment 2. In this embodiment, in order to facilitate transportation and prevent the support rod 5 from tipping over after being placed in the placement rack 11, a pin hole is provided on one side of the placement rack 11 corresponding to the partition rod 10, a positioning hole corresponding to the pin hole is provided on the partition rod 10, and a pin 12 passing through the pin hole and the positioning hole is installed on the placement rack 11. Through the settings of the pin hole, the positioning hole and the pin 12, the opening formed by the placement rack 11 and the partition rod 10 is blocked to prevent the support rod 5 from leaving the placement rack 11 during transportation or after the support rod 5 is placed in the placement rack 11.

[0037] Embodiment 3

[0038] As Figure 1 、 Figure 2 and Figure 5As shown in the figure, the structure of this embodiment is substantially the same as that of Embodiment 2. This embodiment is further optimized on the basis of Embodiment 2. In order to prevent one end of the enclosure net 3 far from the winding shaft 2 from leaving the support rod 5, limit balls 13 are installed at the ends of the two limit strips 4 far from the winding shaft 2. The volume of the limit ball 13 is larger than that of the limit bayonet 6. The support rod 5 is located between the limit ball 13 and the winding shaft 2. By providing the limit ball 13, it is prevented that the support rod 5 leaves the limit strip 4, so that the limit strip 4 is always located within the limit bayonet 6, and the support rod 5 is always located on the enclosure net 3.

[0039] In this embodiment, the support rod 5 is an umbrella-shaped fence support. By providing the umbrella-shaped fence support, the stability of the support rod 5 is improved, and a supporting force is provided for the enclosure net 3.

[0040] In order to facilitate the handling of the vehicle body 1, handles 14 are installed on both the vehicle body 1 and the placement rack 11.
