DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figure 1-Figure 6As shown, a construction engineering protection net proposed in one embodiment of the present application includes:

[0027] Two columns 1, a mounting plate 2 is provided at the bottom of the column 1, and mounting holes 3 are provided at the four corners of the mounting plate 2. A protective net 4 is connected between the two columns 1. When installing the protective net, the two columns 1 are erected so that the mounting plate 2 is placed on the ground. The mounting plate 2 is fixed to the ground through the cooperation of anchor rods or bolts and the mounting holes 3, thereby fixing the two columns 1. The protective net 4 can effectively play the role of enclosure;

[0028] The rotating rod 5 and the sleeve 6, the rotating rod 5 is rotatably arranged between the two columns 1 and is located above the protection net 4, the sleeve 6 is coaxially sleeved on the rotating rod 5, both ends of the sleeve 6 are constructed with end plates and the end plates are fixedly connected to the rotating rod 5, the sleeve 6 has a larger diameter because its end plate is fixed to the rotating rod 5, and there is a larger interval between the sleeve 6 and the rotating rod 5, the sleeve 6 is a cylindrical structure, and its outer surface is relatively smooth, and it also has a larger diameter, when pedestrians climb, the outer surface of the sleeve 6 is smooth, and they cannot use their palms to grab and use leverage, and at the same time, the rotating rod 5 is rotatably connected to the column 1, as long as the pedestrian's hand touches the sleeve 6 to try to grab and use leverage, the rotating rod 5 drives the sleeve 6 to rotate synchronously, so that the pedestrian cannot grab and use leverage, and the pedestrian cannot climb over the protection net;

[0029] The overall structure of the device utilizes the rotation arrangement on the rotating rod 5 and the sleeve 6, utilizing both the smooth curvature of the sleeve 6 surface and the force rotation of the sleeve 6 to prevent pedestrians from climbing over the protective net, thereby improving the overall anti-climbing and anti-overtaking effect of the protective net.

[0030] like Figure 6As shown, in some embodiments, a plug-in slot 7 connected to the top is provided on one side of the column 1, and the plug-in slot 7 includes a connected arc-shaped slot 701 and a rectangular slot 702. A screw 8 is threadedly inserted on the column 1, and a threaded hole that is threadedly matched with the screw 8 is provided on the top of the column 1. A fixing plate 9 is movably sleeved on the screw 8, and an arched portion 10 that is plugged and matched with the rectangular slot 702 is provided at the end of the fixing plate 9. The end of the rotating rod 5 is rotatably inserted in the arc-shaped slot 701. Since the sleeve 6 has a large diameter, the protective net as a whole is not convenient for stacking and transportation. By providing the plug-in slot 7 and the fixed plate 9, the rotating rod 5 and the sleeve 6 can be detachably installed, which is convenient for separate placement and transportation. During installation, first Fix the two columns 1 to the ground, insert the two ends of the rotating rod 5 into the arc grooves 701 on the two columns 1 respectively, then sleeve the fixing plate 9 on the screw 8, thread the screw 8 into the column 1, and then tighten the screw 8, so that the arched portion 10 at the end of the fixing plate 9 is inserted into the rectangular groove 702. The cooperation between the arched portion 10 and the arc groove 701 can limit the rotating rod 5 without affecting the normal rotation of the rotating rod 5. It should be noted that bearing wheels are sleeved at both ends of the rotating rod 5, and the bearing wheels are rotatably inserted in the arc groove 701 to reduce the friction between the rotating rod 5 and the inner wall of the arc groove 701 or the arched portion 10, so that the sleeve 6 can rotate more smoothly when it is subjected to stress, so as to ensure the anti-climbing and overturning effect.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, a slide groove 11 connected to the arc groove 701 is opened on one side of the column 1, and a connecting frame 12 is set on the outer side of the protective net 4. The connecting frame 12 is slidably inserted in the slide groove 11. Through the opened slide groove 11 and the set connecting frame 12, the protective net 4 and the column 1 can also be detachably connected, which is more convenient for transportation and transfer. When connection is required, the two ends of the connecting frame 12 are first inserted into the slide groove 11 from the plug-in grooves 7 on the two columns 1, and then the rotating rod 5 and the sleeve 6 are installed. The installation and disassembly are convenient, thereby improving practicality.

[0032] like Figure 3 As shown, in some embodiments, the cross-section of the slide groove 11 is constructed as a T-shape, and T-shaped blocks 13 are provided on opposite sides of the connecting frame 12, and the T-shaped blocks 13 are slidably inserted in the slide groove 11. By constructing the slide groove 11 as a T-shaped groove, a T-shaped block 13 that slides with the T-shaped groove is provided on the connecting frame 12. When the T-shaped block 13 is slidably inserted in the slide groove 11, the connection strength between the connecting frame 12 and the two columns 1 can be improved, and the resistance to lateral tensile stress between the three can be improved to ensure the overall strength of the protective net.

[0033] like Figure 3As shown, in some embodiments, a reinforcing frame 14 is provided in the connecting frame 12 and the reinforcing frame 14 is fixedly connected to the protective net 4. The reinforcing frame 14 is provided to improve the connection strength between the protective net 4 and the connecting frame 12, and also improve the impact resistance and impact strength of the protective net 4, thereby improving practicality.

[0034] like Figure 5 As shown, in some embodiments, a plurality of reinforcing rods 15 distributed in a ring shape are connected between the rotating rod 5 and the sleeve 6. The reinforcing rods 15 are provided to support and strengthen the sleeve 6 to prevent it from being easily crushed by force, ensure that it can rotate smoothly, and ensure the anti-climbing and overturning effect.

[0035] like Figure 5 As shown, in some embodiments, convex plates are constructed at both ends of the top of the connecting frame 12, and a supporting column 16 is rotatably arranged between the two convex plates. The supporting column 16 and the sleeve 6 are rollingly overlapped. Preferably, the number of the supporting columns 16 is two. By setting the supporting columns 16, it can be ensured that the sleeve 6 can rotate smoothly, and the gap between the sleeve 6 and the connecting frame 12 is reduced, thereby preventing pedestrians from inserting rods or other things into the gap to limit the rotation of the sleeve 6, so as to ensure the anti-climbing and overturning effect.

[0036] like Figure 1 and Figure 6 As shown, in some embodiments, the number of the plug-in slots 7 and the slide slots 11 are both two and are respectively distributed on the opposite sides of the column 1. By providing the plug-in slots 7 and the slide slots 11 on the opposite sides of the column 1, when the protective nets are connected over a long distance, two adjacent protective nets 4 can share one column 1, which not only reduces the number of columns 1 but also simplifies the installation steps.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
