Technical Field
[0001] This utility model belongs to the field of bridge construction safety technology, specifically relating to a safety protection device for ultra-high formwork support. Background Technology
[0002] Bridge construction is an extremely professional and complex process. In the series of procedures after the completion of the main bridge project, workers are often required to work frequently at the edge of the bridge. These tasks include, but are not limited to, the construction of crash barriers, the paving of the bridge deck, the installation of lighting and signs, as well as inspection and maintenance. This series of rigorous and complex high-altitude operations requires a lot of time and effort. Because the content is repetitive and tedious, and the time is long, workers are most likely to be distracted and have a reduced sense of safety. Being located at the edge of the bridge, it is the job with the highest risk of accidents.
[0003] In existing technical measures, workers typically use a safety rope to ensure their safety. One end of the rope is attached to an extended pre-embedded steel ring, and the other end is connected to the worker's safety harness. However, this method has obvious drawbacks: First, if a worker falls from a height, the tension of the safety rope may cause them to swing in the air like a swing, increasing the risk of injury from collision. Second, to ensure ease of movement for workers during construction, the safety rope is usually kept to a certain length. This means that workers can only be caught by the rope after falling a certain distance, by which time they may have already reached a considerable speed. Furthermore, the rope lacks elasticity, making it prone to strangulation injuries and breakage.
[0004] To mitigate this issue, some safety rope devices employ a locking design, similar in principle to a car seatbelt. When the falling speed becomes too high, centrifugal force triggers a locking mechanism to prevent further release of the rope. However, due to the complexity of the construction environment and the large range of movement of workers, sudden movements can cause the rope to extend too quickly, accidentally triggering the centrifugal mechanism and resulting in frequent activation of the safety device, thus impacting construction efficiency. Furthermore, if the centrifugal locking mechanism is only triggered when a worker falls to a certain speed, it could potentially cause strangulation injuries.
[0005] Therefore, a protective device is needed that allows construction workers to work at heights safely and conveniently. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a safety protection device for ultra-high formwork, which addresses the shortcomings of the prior art. The device has a simple structure and reasonable design. By setting a safety buckle and an adjustment box, workers can easily adjust the length of the safety belt extending from the adjustment box at any time and in a slow, short distance, thus expanding the workspace. It also eliminates the need for a retractor, avoiding accidental activation of the centrifugal mechanism, and offers high flexibility and timeliness. Furthermore, by adjusting the distance between the safety buckle and the rotation auxiliary component, the safety belt is prevented from drooping onto the construction platform and affecting workers, thus improving safety.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a safety protection device for ultra-high formwork support, including a safety buckle, a rotation auxiliary component and a safety belt. The safety buckle and the rotation auxiliary component are both passed through the first guide rail and the second guide rail. An adjustment box is provided on one end of the safety buckle located outside the second guide rail. One end of the safety belt is connected to a retractor, and the other end of the safety belt passes through the safety buckle, the rotation auxiliary component and the adjustment box in sequence and is connected to a safety ring. The upper and lower surfaces of the seat belt are evenly provided with a plurality of first elastic protrusions; The adjustment box is provided with two limiting plates, which are located on the upper and lower sides of the seat belt respectively. A plurality of second elastic protrusions are evenly provided on one side of the limiting plate, and the plurality of first elastic protrusions and the plurality of second elastic protrusions are interlocked. A support mechanism is provided on the other side of the limiting plate.
[0008] Furthermore, the first and second guide rails are horizontally erected on the ultra-high formwork support.
[0009] Furthermore, both the safety buckle and the rotation auxiliary component are provided with through holes in the middle for the seat belt to pass through, and the inner wall of the through holes is provided with a rubber wear-resistant layer.
[0010] Furthermore, the adjustment box has a first opening on the left and right sides for the seat belt to pass through, and a second opening on the left and right sides for the limiting plate to extend out. A Z-shaped folding plate for covering the second opening is connected to the side of the limiting plate away from the seat belt.
[0011] Furthermore, the support mechanism includes two hydraulic rods arranged in a scissor shape, an mounting plate is provided on the inner side wall of the adjustment box, a slide rail is provided on the limiting plate, the fixed end of the hydraulic rod is mounted on the mounting plate through a rotating support, and the telescopic end of the hydraulic rod is slidably mounted on the slide rail through a sliding support.
[0012] This utility model has the following advantages compared with the prior art: 1. This utility model is simple and quick to operate. By setting a safety buckle and adjustment box, it is easy for workers to adjust the length of the safety belt extending out of the adjustment box in a short distance according to their own action needs. No retractor is required for work, which is highly flexible and timely.
[0013] 2. By setting the first elastic protrusion and the second elastic protrusion to cooperate with each other, this utility model makes it easy to use the adjustment box to limit the safety belt with medium intensity. This allows workers to shorten or lengthen the safety belt slowly and over short distances at any time to adjust their activity space, while also avoiding the safety belt from being released too quickly due to sudden movements, thereby avoiding accidental activation of the centrifugal mechanism of the retractor.
[0014] 3. This utility model, by setting a slewing auxiliary component, facilitates the length of the safety belt located outside the extended retractor, increasing the worker's range of motion. The slewing auxiliary component is used to suspend the middle of the safety belt, and by adjusting the distance between the safety buckle and the slewing auxiliary component, the safety belt is prevented from drooping on the construction platform and affecting the worker, thus improving safety.
[0015] In summary, this utility model has a simple structure and reasonable design. By setting a safety buckle and adjustment box, it is convenient for workers to adjust the length of the safety belt extending out of the adjustment box at any time and at a slow speed and short distance, which expands the working space. Moreover, it does not require a retractor to work, avoiding accidental activation of the centrifugal mechanism, and has strong flexibility and timeliness. By adjusting the distance between the safety buckle and the rotation auxiliary component, it prevents the safety belt from falling on the construction platform and affecting the workers, thus improving safety.

Detailed Implementation
[0022] like Figures 1 to 4 As shown, this utility model includes a safety buckle 3, a rotation auxiliary component 4, and a safety belt 5. The safety buckle 3 and the rotation auxiliary component 4 are both mounted on the first guide rail 1 and the second guide rail 2. An adjustment box 7 is provided on one end of the safety buckle 3 located outside the second guide rail 2. One end of the safety belt 5 is connected to the retractor, and the other end of the safety belt 5 passes through the safety buckle 3, the rotation auxiliary component 4, and the adjustment box 7 in sequence and is connected to the safety ring on the worker's body.
[0023] The upper and lower surfaces of the seat belt 5 are evenly provided with a plurality of first elastic protrusions 6.
[0024] The adjustment box 7 is provided with two limiting plates 8, which are located on the upper and lower sides of the seat belt 5 respectively. A plurality of second elastic protrusions 9 are evenly provided on one side of the limiting plate 8, and a plurality of first elastic protrusions 6 and a plurality of second elastic protrusions 9 are interlocked. A support mechanism is provided on the other side of the limiting plate 8.
[0025] In this embodiment, the first guide rail 1 and the second guide rail 2 are horizontally erected on the ultra-high formwork support frame, which facilitates a dual stabilizing effect.
[0026] In actual use, by setting up safety buckle 3 and adjustment box 7, workers can easily adjust the length of the safety belt 5 extending out of the adjustment box 7 by a short distance according to their own action needs, without the need for a retractor, which is highly flexible and timely.
[0027] It should be noted that by setting the first elastic protrusion 6 and the second elastic protrusion 9 to cooperate with each other, it is convenient to use the adjustment box 7 to limit the safety belt 5 with moderate strength. This allows workers to shorten or lengthen the safety belt 5 slowly and by short distance at any time to adjust their activity space, while also avoiding the safety belt 5 from being released too quickly due to sudden movements, thereby avoiding accidental activation of the centrifugal mechanism of the retractor.
[0028] In actual use, by setting the slewing auxiliary component 4, the length of the safety belt 5 located outside the extended retractor is facilitated, increasing the range of motion for workers. The middle part of the safety belt 5 is lifted by the slewing auxiliary component 4, and then the distance between the safety buckle 3 and the slewing auxiliary component 4 is adjusted to prevent the safety belt 5 from falling on the construction platform and affecting workers, thus improving safety.
[0029] It should be noted that the safety buckle 3 and the rotation auxiliary component 4 are both symmetrical plate structures. The two plate structures are fastened and clamped on the first guide rail 1 and the second guide rail 2 by bolts to achieve connection. The position can be adjusted by tightening the bolts when needed.
[0030] In this embodiment, both the safety buckle 3 and the rotation auxiliary component 4 are provided with through holes for the safety belt 5 to pass through, and the inner wall of the through holes is provided with a rubber wear-resistant layer.
[0031] In actual use, by setting a rubber wear-resistant layer, it is easy to increase the resistance of the seat belt 5 in the safety buckle 3 and the rotation auxiliary component 4, thereby realizing the mobility of the seat belt 5 and avoiding the safety hazards caused by the rapid stretching or tightening of the seat belt 5.
[0032] It should be noted that the rubber wear layer is a rubber wear pad.
[0033] In this embodiment, the adjustment box 7 has a first opening on the left and right sides for the seat belt 5 to pass through, and a second opening on the left and right sides for the limiting plate 8 to extend out. A Z-shaped folding plate 15 for covering the second opening is connected to the side of the limiting plate 8 away from the seat belt 5.
[0034] In actual use, the Z-shaped folding plate 15 can fold as the limiting plate 8 moves up and down, which not only allows the limiting plate 8 to move within the second opening, but also seals the second opening between the limiting plate 8 and the side wall of the adjustment box 7 at all times, preventing a large amount of particulate matter from the external environment from entering the adjustment box 7 and affecting its use.
[0035] It should be noted that the left-right direction of the adjustment box 7 is the same as the extension direction of the second guide rail 2.
[0036] like Figure 4 As shown, in this embodiment, the support mechanism includes two hydraulic rods 10 arranged in a scissor shape, an mounting plate 11 is provided on the inner side wall of the adjustment box 7, and a slide rail 13 is provided on the limiting plate 8. The fixed end of the hydraulic rod 10 is mounted on the mounting plate 11 through a rotating support 12, and the telescopic end of the hydraulic rod 10 is slidably mounted on the slide rail 13 through a sliding support 14.
[0037] In actual use, the fixed end of the hydraulic rod 10 is rotatably mounted on the rotating support 12, and the telescopic end of the hydraulic rod 10 is rotatably mounted on the sliding support 14. When the telescopic end of the hydraulic rod 10 extends, the two sliding supports 14 move closer to each other along the slide rail 13, and drive the limiting plate 8 to move closer to the safety belt 5 until the first elastic protrusion 6 and the second elastic protrusion 9 engage, thereby limiting the safety belt 5. When the telescopic end of the hydraulic rod 10 retracts, the two sliding supports 14 move further away from each other along the slide rail 13, and drive the limiting plate 8 to move further away from the safety belt 5 until the first elastic protrusion 6 and the second elastic protrusion 9 separate, thereby canceling the limitation on the safety belt 5. At this time, the worker can pull the safety belt 5.
[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
