Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.
[0025] To solve the above problems, Figure 1 As shown, the embodiment of the utility model provides a scaffolding anti-fall structure, comprising an outer support frame 1 and a connecting device 2, wherein the bottom of the outer support frame 1 is fixedly connected to the scaffolding, and the connecting device 2 is slidably arranged on the outer support frame 1; Figure 2 As shown, the connecting device 2 includes a sliding module 3, a rotating module 4 and a buffer module 5; the upper part of the sliding module 3 is slidably connected to the outer support frame 1, the bottom of the sliding module 3 is rotatably connected to the top of the rotating module 4, and the top of the buffer module 5 is rotatably connected to the bottom of the rotating module 4, as shown in FIG. Figure 5 As shown, the buffer module 5 includes a buffer connecting tube 12, a buffer unit 13 and a buffer connecting buckle 14; the top of the buffer connecting tube 12 is rotatably connected to the bottom of the rotating module 4, the buffer unit 13 is slidably arranged in the buffer connecting tube 12, and the top of the buffer connecting buckle 14 is fixedly connected to the bottom of the buffer unit 13.
[0026] It should be noted that the outer support frame 1 is used to support the connecting device 2, and the connecting device 2 can be connected to the workers through a safety belt to prevent the workers from accidentally falling out of the scaffolding and getting injured. The sliding module 3 in the connecting device 2 can slide on the outer support frame 1, thereby driving the rotating module 4 to move horizontally, so that it can flexibly adapt to the horizontal movement needs of the workers on the scaffolding, which does not hinder normal construction operations and can follow the position changes of the workers in real time to ensure that the safety protection is always effective, greatly improving the convenience and safety of the operation. The rotating module 4 can adapt to the rotation of the buffer module 5 during rotation, so that the connecting device 2 can achieve the purpose of preventing workers from accidentally falling out of the scaffolding, and can also adapt to the displacement of workers during construction, thereby reducing the obstruction of workers during construction. When the worker accidentally falls, the buffer module 5 can absorb a large amount of impact energy through the compression deformation of the buffer spring of the buffer unit 13, thereby reducing the direct harm to the worker caused by the fall.
[0027] In one embodiment of the utility model, the buffer connecting cylinder 12 includes a connecting cylinder body, a connecting cylinder arc top and a connecting cylinder slide groove, the connecting cylinder arc top is opened at the top of the connecting cylinder body, and the connecting cylinder slide groove is opened inside the connecting cylinder.
[0028] It should be noted that the connecting cylinder body, as a component of the buffer module 5, can withstand the compression or release energy generated by the buffer spring, and has a strong and durable effect. The arc top of the connecting cylinder can avoid interference with the rotating column 9 when the buffer connecting cylinder 12 rotates. The connecting cylinder slide groove can position the up and down sliding of the buffer positioning rod. The precise guidance of the buffer positioning rod by the connecting cylinder slide groove ensures that the buffer unit 13 can move smoothly according to the predetermined trajectory when it is hit by a fall, thereby realizing the orderly progress of the buffer process. This not only can more effectively absorb the fall energy, but also can reduce unnecessary lateral deviation or shaking, thereby improving safety.
[0029] In one embodiment of the utility model, the buffer unit 13 includes a buffer blocking block, a buffer positioning rod and a buffer spring; the buffer blocking block is slidably arranged in the connecting tube slide groove, the bottom of the buffer blocking block is fixedly connected to the top of the buffer positioning rod, and the buffer spring is sleeved on the buffer positioning rod.
[0030] It should be noted that the buffer spring in the buffer unit 13 can be compressed and deformed when the worker falls, effectively absorbing and dispersing the impact force of the fall, thereby greatly reducing direct damage to the worker's body. The buffer blocking block is slidably arranged in the slide groove of the connecting tube and is connected to the buffer positioning rod, thereby limiting the range of movement of the buffer positioning rod, making the energy absorption process more orderly and controllable. The buffer positioning rod not only serves as a connecting bridge between the blocking block and the buffer spring, but also enhances the structural stability of the entire buffer unit 13. The fixed connection design ensures that under extreme impact force, the components can still maintain a good connection state, thereby improving the overall reliability.
[0031] In one embodiment of the present utility model, the top of the buffer spring contacts the bottom of the buffer blocking block, and the bottom of the buffer spring contacts the bottom of the connecting tube slide groove.
[0032] It should be noted that this ensures that the impact force of the fall can be directly and quickly transmitted to the buffer spring through the buffer block without any unnecessary intermediate links, thereby improving the efficiency and immediacy of energy absorption. When a worker falls, the impact force is immediately absorbed by the buffer spring and converted into elastic potential energy, effectively reducing direct impact damage to the worker. The two ends of the buffer spring are in contact with the blocking block and the bottom of the slide respectively, so that the force can be evenly applied during the compression process, avoiding stress concentration and making the energy absorption process smoother and more uniform.
[0033] In one embodiment of the utility model, the buffer connecting buckle 14 includes a connecting buckle body, a connecting shaft and a connecting groove. The lower part of the buffer positioning rod passes through the connecting tube slide groove and is fixedly connected to the top of the connecting buckle body. The connecting groove is opened at the bottom of the connecting buckle body, and the connecting shaft is rotatably set in the connecting groove.
[0034] It should be noted that the fixed connection between the buffer positioning rod and the connecting buckle body ensures the stability of the force transmission path from the buffer unit 13 to the safety belt. The rotating setting of the connecting shaft in the connecting groove gives the buffer connecting buckle 14 a certain degree of rotation freedom, which means that during the worker's operation, even if the body rotates or tilts naturally, the connecting buckle can adjust the angle accordingly without affecting the normal function of the safety belt, thereby improving the comfort and safety during operation. The connecting shaft in the connecting buckle is connected to one end of the safety belt, making installation and disassembly simple and quick.
[0035] In one embodiment of the present invention, the outer support frame 1 includes a support frame body and a sliding groove; two sliding grooves are respectively opened on both sides of the support frame body.
[0036] It should be noted that the support frame body, as the basis of the entire anti-fall structure, provides sufficient strength and rigidity to support the weight of the connecting device 2 and other components. The sliding grooves on both sides provide a smooth and stable sliding track for the sliding module 3, which allows the connecting device 2 to slide freely along the support frame body to meet the needs of workers in different working positions, increases the flexibility and convenience of the operation, and also simplifies the installation and adjustment process. The presence of the sliding grooves enables the safety protection device to move smoothly with the workers when they move in different working areas, without the need to frequently unfasten and re-fasten it, which greatly reduces the time waste and safety hazards caused by adjusting the protective equipment, and improves the continuity and safety of the operation.
[0037] In one embodiment of the present invention, Figure 3 As shown, the sliding module 3 includes a sliding connection frame 6, a sliding wheel 7 and a sliding connection shaft 8; one end of the two sliding connection shafts 8 are respectively fixedly connected to the inner wall of the sliding connection frame 6, and the other ends of the two sliding connection shafts 8 are respectively rotatably connected to the center of the two sliding wheels 7, and the two sliding wheels 7 are respectively arranged in the two sliding grooves.
[0038] It should be noted that the sliding wheel 7 is embedded in the sliding groove, and with the low-friction design, the entire sliding module 3 can move smoothly along the slides on both sides of the support frame body, reducing the resistance and noise during the sliding process, and can remain smooth even under long-term use or heavy load conditions, thereby improving the comfort and efficiency of the operation. The two ends of the sliding connecting shaft 8 are respectively fixed to the inner wall of the sliding connecting frame 6 and the center of the sliding wheel 7, forming a stable support structure, enhancing the overall rigidity and load-bearing capacity of the sliding module 3, and ensuring that when workers are working, even in the face of sudden external force impacts, they can remain stable and reduce the risk of sliding derailment.
[0039] In one embodiment of the present invention, Figure 4 As shown, the rotating module 4 includes a rotating column 9, a rotating groove 10 and a rotating connecting shaft 11; the rotating groove 10 is opened at the upper part of the rotating column 9 and is rotatably connected to the bottom of the sliding connecting frame 6, and the rotating connecting shaft 11 passes through the upper part of the rotating column 9 and the buffer positioning rod respectively.
[0040] It should be noted that the rotating connection design between the rotating groove 10 and the bottom of the sliding connecting frame 6 enables the entire connecting device 2 to freely rotate in the horizontal direction according to the working needs of the workers, adapting to different working surfaces and working angles, greatly improving the working flexibility and comfort.
[0041] The rotating column 9 in the rotating module 4 must not only ensure the flexibility of rotation, but also have sufficient torsional strength to withstand various dynamic loads during operation, ensuring that it will not be twisted or damaged under frequent rotation and stress conditions, thereby improving the stability and safety of the entire system.
[0042] It should be noted that the above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
