Description

Technical Field

[0001] The invention belongs to the technical field of anti-fall protection nets, and in particular relates to an assembled anti-fall double-layer protection net for super-high towers. Background Art

[0002] When conducting high-altitude operations such as inspection and maintenance on super-high towers such as power towers and communication base station towers, in order to minimize the risk of people falling and effectively catch fallen equipment parts, an anti-fall protection net is installed on the tower body. The protection net can effectively intercept people who fall accidentally and prevent them from falling directly to the ground and causing serious casualties.

[0003] The current anti-fall net is generally set up in a single layer. When the single-layer net is subjected to a large impact force, it is more prone to deformation and breakage. At the same time, the structure of the single-layer net is relatively simple. When intercepting falling objects, it can provide fewer buffer layers and space, and cannot convert and dissipate the kinetic energy of the fall well, which reduces the use intensity of the protective net. On the other hand, there are certain problems with the adaptive adjustment of the protective net. During the construction of the tower group, the cross-section of the tower changes with the height of the tower, so the shape and hanging points of the protective net also need to be changed accordingly. The fixed-size protective net solution can no longer meet the construction needs. When the protective net moves down and up, the outer hanging points are at a high altitude. If they rely on manual adjustment, the risk is extremely high. In serious cases, it may cause casualties and threaten life safety.

[0004] Therefore, an assembled double-layer anti-fall protection net for super-high towers with stronger impact resistance, more buffering layers and a larger protection range is urgently needed. Summary of the Invention

[0029] Example 1:

[0030] In this embodiment, an assembled double-layer anti-fall protection net for a super high tower is provided. Figures 1 to 6As shown, it includes an outer net 1, an inner net 2 and a side net 3. The outer net 1, the inner net 2 and the side net 3 are all nylon rope protection nets. The inner net 2 is arranged above the outer net 1 to form a double-layer protection structure. Hanging rings 28 are provided on the outer sides of the four corners of the outer net 1 so that the outer net 1 can be hung on the tower body of the super-high tower. Buffer devices are connected between the four corners of the inner net 2 and the outer net 1. The buffer devices can initially reduce the impact when the inner net 2 is impacted to avoid the impact directly acting on the outer net 1. Cross bars 4 are provided on both side ends of the outer net 1. Both ends of the cross bar 4 are provided with an opening adjustment mechanism. Side nets 3 are provided between two adjacent opening adjustment mechanisms. The opening adjustment mechanism is used to open the side net 3 to expand the protection area. The inner side of the side net 3 is connected to the outer net 1, and the outer ends of the side net 3 are connected to the adjustment ends of the opening adjustment mechanism.

[0031] By adopting this structure, by setting the above-mentioned outer net 1 and inner net 2, the above-mentioned inner net 2 is installed above the above-mentioned outer net 1 through the above-mentioned buffer device, which can more strongly absorb falling objects and provide more buffering layers, thereby improving the protective strength of the protective net, and then the above-mentioned side net 3 is expanded to different degrees through the above-mentioned opening adjustment mechanism, thereby increasing the anti-fall protection range of the protective net and improving the protection effect.

[0032] As a specific implementation of this embodiment, Figure 3 As shown, the buffer device includes a buffer cylinder 5, a first fixing ring 6, a second fixing ring 7, a first connecting rope 8 and a second connecting rope 9. Specifically, the four corners of the inner net 2 are fixed with the first fixing ring 6, and the four corners of the inner wall of the outer net 1 are fixed with the first connecting rope 8. One end of the buffer cylinder 5 is provided with a ring 10, and a buffer mechanism is provided inside the buffer cylinder 5. The second fixing ring 7 is connected in series between the first connecting rope 8 and the ring 10. The ring 10 is provided with an assembly mechanism for separating the second fixing ring 7. The second fixing ring 7 and the ring 10 can be quickly untied by the assembly mechanism so as to perform separate maintenance on the inner net 2 and the outer net 1. One end of the second connecting rope 9 is fixed on the first fixing ring 6, and the other end of the second connecting rope 9 is connected to the buffer mechanism inside the buffer cylinder 5. The impact force exerted on the inner net 2 is transmitted to the buffer cylinder 5 through the second connecting rope 9, and is buffered by the buffer mechanism inside the buffer cylinder 5, thereby avoiding the impact force from directly acting on the outer net 1.

[0033] In this embodiment, Figure 5As shown, the buffer mechanism includes a push plate 11 and a guide plate 12. The inner wall of the buffer cylinder 5 is provided with a fixed rod 13. The middle part of the push plate 11 is rotatably sleeved on the fixed rod 13. The other end of the buffer cylinder 5 is provided with a hole. The second connecting rope 9 is inserted into the buffer cylinder 5 through the hole and is fixedly connected to the lower end of the push plate 11. The impulse can drive the push plate 11 to rotate around the fixed rod 13 through the second connecting rope 9. The inner wall of the buffer cylinder 5 is fixedly provided with a connecting plate 14. The connecting plate 14 is located above the hole. One end of the guide plate 12 is rotatably connected to the connecting plate 14 through a pin 15, and the guide plate 12 can rotate around the pin 15. A strip hole is provided on the guide plate 12, and a pull rod 16 is fixed to the upper end of the push plate 11. The pull rod 16 slides through the strip hole, and a buffer spring 17 is provided between the pull rod 16 and the end wall of the strip hole. When the inner net 2 is impacted, the push plate 11 and the guide plate 12 can swing back and forth under the action of the buffer spring 17, thereby gradually buffering the impact and avoiding direct impact on the outer net 1.

[0034] As an optimization, a limiting ring 18 is sleeved on the end of the above-mentioned pull rod 16, and the above-mentioned limiting ring 18 and the push plate 11 are respectively arranged on both sides of the above-mentioned guide plate 12. The above-mentioned push plate 11 swings under the force, driving the above-mentioned pull rod 16 to slide in the above-mentioned strip hole, so that the above-mentioned guide plate 12 swings with the above-mentioned pin shaft 15 as the center, and the sliding above-mentioned pull rod 16 is subjected to the force of the above-mentioned buffer spring 17, thereby neutralizing and buffering the impact on the above-mentioned inner net 2.

[0035] In this embodiment, Figure 6 As shown, the above-mentioned assembly mechanism includes two symmetrically arranged clamping plates 19, an opening 20 is provided on one side of the above-mentioned ring 10, and a rotating rod 21 is rotatably passed through one end of the above-mentioned ring 10 close to the opening 20, and a protruding column 22 is provided on the outer wall of the other end of the above-mentioned ring 10 close to the opening 20. The above-mentioned rotating rod 21 is sleeved with a torsion spring, and one end of the two above-mentioned clamping plates 19 is fixedly sleeved on the two ends of the above-mentioned rotating rod 21, and the other end of the above-mentioned clamping plate 19 is provided with a clamping groove 23 that cooperates with the above-mentioned protruding column 22. The force of the torsion spring forces the clamping groove 23 on the above-mentioned clamping plate 19 to be tightly clamped with the above-mentioned protruding column 22, thereby blocking the above-mentioned opening 20 and preventing the above-mentioned second fixing ring 7 from detaching from the above-mentioned ring 10 during use.

[0036] In this embodiment, Figure 4As shown, the above-mentioned opening adjustment mechanism includes a connecting ring 24, an internally threaded sleeve 25 and an adjusting screw 26 threadedly connected to the above-mentioned internally threaded sleeve 25. One end of the above-mentioned internally threaded sleeve 25 is fixedly connected to the above-mentioned cross bar 4, and the above-mentioned adjusting screw 26 extends from the other end of the above-mentioned internally threaded sleeve 25. The end of the above-mentioned adjusting screw 26 that extends out is provided with a top ring 27, and the above-mentioned top ring 27 is mounted on the above-mentioned adjusting screw 26 through a universal head. When the above-mentioned adjusting screw 26 is adjusted, the above-mentioned top ring 27 will not rotate with the above-mentioned adjusting screw 26, thereby preventing the above-mentioned side net 3 from being entangled. One end of the above-mentioned connecting ring 24 is sleeved with the above-mentioned top ring 27, and the other end of the above-mentioned connecting ring 24 is sleeved with the outer end of the above-mentioned side net 3. By adjusting the above-mentioned adjusting screw 26 to extend and retract along the above-mentioned internally threaded sleeve 25, the above-mentioned top ring 27 is pushed, and the above-mentioned side net 3 between two adjacent connecting rings 24 is pulled and slowly opened, thereby completing the adjustment of the protection range of the above-mentioned side net 3.

[0037] After the assembled anti-fall double-layer protective net for super high towers is assembled, it is installed on the tower body of the super high tower through the above-mentioned hanging ring 28. When an object falls, the falling object first contacts the above-mentioned inner net 2. At this time, the above-mentioned second connecting ropes 9 at the four corners of the above-mentioned inner net 2 pull the above-mentioned push plate 11 inside the buffer tube 5, so that the above-mentioned push plate 11 rotates around the above-mentioned fixed rod 13, and at the same time drives the above-mentioned pull rod 16 to slide in the above-mentioned strip hole. At this time, the above-mentioned pull rod 16 pulls the above-mentioned buffer spring 17, and the elastic force of the above-mentioned buffer spring 17 pulls back to preliminarily offset the impact. While the above-mentioned push plate 11 rotates, the above-mentioned guide plate 12 is pushed, and then swings through the rotation cooperation of the above-mentioned pin shaft 15 and the connecting plate 14, ensuring that the above-mentioned buffer spring 17 can be stably pulled. When the falling object contacts the above-mentioned inner net 2 and drives the buffer mechanism inside the above-mentioned buffer tube 5 for buffering, it contacts the above-mentioned outer net 1, and the impact is finally converted and offset by the above-mentioned outer net 1, thereby improving the impact strength and service life of the protective net.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
