Description

Technical Field

[0001] This invention relates to the field of bridge construction safety protection technology, specifically a bridge construction safety protection and isolation device. Background Technology

[0002] Bridge construction safety is a crucial aspect of all types of engineering construction, directly impacting not only the lives of construction workers but also the daily travel safety of surrounding residents. Construction safety is a broad and in-depth concept, encompassing not only direct safety risk control at the work site but also efficient safety management capabilities, occupational health care for construction workers, and a civilized construction environment. To ensure the smooth progress of construction activities, a series of effective measures must be taken to prevent and control potential safety hazards. During construction, setting up safety isolation devices is a key step in protecting the construction site and preventing unauthorized personnel or vehicles from entering. These isolation devices aim to clearly define the construction area, effectively isolating construction activities from the external environment and reducing the occurrence of accidents.

[0003] However, traditional safety protection and isolation devices for bridge construction, such as guardrails, barriers, and cones, while providing some degree of isolation, often neglect human-centered and safety considerations in their design. When construction workers or people in the vicinity accidentally fall or collide with these isolation devices, the lack of necessary cushioning mechanisms means that direct, rigid impacts can easily lead to bodily injuries, ranging from minor abrasions to fractures or even more serious consequences. Therefore, we propose a new type of safety protection and isolation device for bridge construction. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a bridge construction safety protection and isolation device that solves the problem that traditional bridge construction safety protection and isolation devices, such as guardrails, isolation fences, and cones, lack necessary buffering mechanisms, which can easily lead to injuries to construction workers or people in the surrounding area when they accidentally fall or are hit.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bridge construction safety protection and isolation device, comprising a bracket and a base fixedly installed at the bottom of the bracket, a splicing groove fixedly installed on one side of the bracket, a splicing block that mates with the splicing groove fixedly installed on the other side of the bracket, and an elastic mechanism provided on the inner side of the bracket.

[0006] The elastic mechanism includes a mounting component, a first elastic component, and a second elastic component.

[0007] The mounting assembly includes several mounting rods fixedly mounted inside the bracket. One end of each mounting rod is fixedly mounted with a mounting ring. Several base columns are fixedly mounted on the inner circular surface of the mounting ring. A collar coaxial with the mounting ring is fixedly mounted on the end of each base column away from the mounting ring.

[0008] The first elastic component includes a telescopic spring fixedly installed on the outer circular surface of the base column. One end of the telescopic spring is fixedly installed with a slider that is slidably connected to the base column. The top of the slider is rotatably connected with an inclined rod. The end of the inclined rod away from the slider is rotatably connected with a linkage frame. A linkage ring is fixedly installed on the outer side of the linkage frame. An elastic mesh is fixedly installed on the inner circular surface of the linkage ring. A fluorescent coating is provided on the outer side of the linkage ring.

[0009] The second elastic component includes a guide post fixedly installed on the linkage frame and passing through the mounting ring and the collar. Several unit airbags are fixedly installed on the outer circular surface of the guide post, and an anti-detachment block is fixedly installed at the end of the guide post away from the linkage frame.

[0010] The second elastic component also includes an airbag limiting disc that is fixedly mounted on the collar and slidably connected to the guide post.

[0011] Preferably, ground nails are movably installed at the four corners of the base, wherein the ground nails are made of stainless steel.

[0012] Preferably, the elastic mesh is made of several stainless steel wires interwoven together, wherein the elastic mesh as a whole is convex in an arc shape.

[0013] Preferably, the inner cavities of the plurality of unit airbags are interconnected, wherein the plurality of unit airbags are fixedly installed between the linkage frame and the airbag limiting plate.

[0014] Preferably, the anti-detachment block is hexagonal prism in shape, wherein the volume of the anti-detachment block is larger than the volume of the collar.

[0015] Preferably, the linkage frame is composed of a linkage disc and several linkage support rods, wherein the several linkage support rods are evenly fixedly installed on the outer circular surface of the linkage disc.

[0016] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0017] 1. This invention significantly improves the ergonomics and safety of the device by incorporating an elastic net. This elastic net is woven from several interlaced stainless steel wires, forming an arc-shaped convex shape with excellent elasticity and cushioning properties. When construction workers or nearby personnel accidentally fall or collide with the device, the elastic net can immediately undergo elastic deformation, absorbing and reducing most of the impact force, thus providing initial and effective protection for the impacted person. This design avoids the direct rigid collision injuries caused by the lack of a cushioning mechanism in traditional isolation devices, greatly reducing the risk of personnel injury.

[0018] 2. This invention further enhances the device's buffering and force-dissipating capabilities by incorporating a first elastic component. As the impact force continues to be transmitted, the telescopic spring in the first elastic component is compressed, the slider slides outward along the base column, and simultaneously the diagonal rod expands outward, pushing the linkage frame backward. This series of actions works together to further weaken the impact force, providing greater protection for the impactor. This multi-stage buffering mechanism allows the device to more effectively disperse and absorb energy upon impact, thereby reducing potential injury to personnel.

[0019] 3. This invention achieves further absorption and dispersion of impact force by incorporating a second elastic component. When the linkage moves backward, the guide post in the second elastic component and several unit airbags fixedly installed on its outer circumference are compressed accordingly. The internal cavities of these unit airbags are interconnected, enabling them to collectively absorb and disperse the impact force, further reducing the injury suffered by the impactor.

[0020] 4. When the elastic net, telescopic spring, and unit airbag of this invention are compressed to a certain extent, they begin to recover and generate an outward force, gently pushing the impactor into the device, thereby reducing the risk of the impactor colliding with the device again due to inertia. This design not only improves the safety performance of the device, but also allows the device to return to its original state more quickly after being impacted, ready for the next use.

[0037] This invention provides a technical solution:

[0038] Please see Figures 1-6 A bridge construction safety protection and isolation device includes a bracket 1 and a base 2 fixedly installed at the bottom of the bracket 1. A splicing groove 3 is fixedly installed on one side of the bracket 1, and a splicing block 4 that cooperates with the splicing groove 3 is fixedly installed on the other side of the bracket 1. An elastic mechanism 5 is provided on the inner side of the bracket 1.

[0039] The elastic mechanism 5 includes an installation component 51, a first elastic component 52, and a second elastic component 53. Through the installation component 51, the first elastic component 52, and the second elastic component 53, multi-level buffering and stress relief functions are realized, effectively solving the problem that traditional isolation devices lack buffering mechanisms and are prone to causing personal injury.

[0040] The mounting assembly 51 includes several mounting rods 511 fixedly mounted inside the bracket 1. A mounting ring 512 is fixedly mounted at one end of each mounting rod 511. Several base columns 513 are fixedly mounted on the inner circular surface of the mounting ring 512. A collar 514 coaxial with the mounting ring 512 is fixedly mounted at the end of each base column 513 away from the mounting ring 512. Through the fixed mounting of the mounting rods 511, mounting ring 512, base columns 513 and collar 514, a stable support structure is provided for the first elastic component 52 and the second elastic component 53, ensuring that the entire elastic mechanism 5 can work stably when subjected to impact and effectively disperse the impact force.

[0041] The first elastic component 52 includes a telescopic spring 521 fixedly installed on the outer circular surface of the base column 513. One end of the telescopic spring 521 is fixedly installed with a slider 522 that is slidably connected to the base column 513. The top of the slider 522 is rotatably connected with a diagonal rod 523. The end of the diagonal rod 523 away from the slider 522 is rotatably connected with a linkage frame 524. A linkage ring 525 is fixedly installed on the outer side of the linkage frame 524. An elastic net 526 is fixedly installed on the inner circular surface of the linkage ring 525. A fluorescent coating 527 is provided on the outer side of the linkage ring 525. Through the linkage of the telescopic spring 521, slider 522, diagonal rod 523, linkage frame 524 and elastic net 526, a multi-level buffer structure is formed, which effectively absorbs and disperses the impact force. At the same time, the fluorescent coating 527 improves the visibility at night, thus enhancing the safety protection performance of the device.

[0042] The second elastic component 53 includes a guide post 531 fixedly mounted on the linkage frame 524 and passing through the mounting ring 512 and the shaft collar 515. Several unit airbags 532 are fixedly mounted on the outer circular surface of the guide post 531. An anti-detachment block 533 is fixedly mounted on the end of the guide post 531 away from the linkage frame 524. The unit airbags 532 on the guide post 531 further absorb and disperse the impact force, and the anti-detachment block 533 ensures that the guide post 531 will not fall off. Overall, the safety protection performance of the device is enhanced and the risk of impact injury is reduced.

[0043] The second elastic component 53 also includes an airbag limiting disk 534 that is fixedly mounted on the collar 515 and slidably connected to the guide post 531. By being fixedly mounted on the collar 515 and slidably connected to the guide post 531, it ensures that the unit airbag 532 can be stably compressed and the movement range of the guide post 531 is limited when it is impacted, thereby improving the safety and stability of the device.

[0044] Furthermore, ground nails are movably installed at the four corners of the base 2. These ground nails are made of stainless steel. By using stainless steel for the ground nails and movably installing them at the four corners of the base 2, the stability and durability of the device are enhanced, ensuring that the device can be stably installed in different environments, effectively isolating the construction area and preventing accidents.

[0045] Furthermore, the elastic net 526 is made of several stainless steel wires interwoven together. The elastic net 526 is generally convex in an arc shape. By using stainless steel wires to weave the elastic net 526 and making it convex in an arc shape, its elasticity and cushioning performance are enhanced, which can effectively absorb impact force and initially protect the impacted person. At the same time, the stainless steel material improves durability and safety.

[0046] Furthermore, the inner cavities of several unit airbags 532 are interconnected, and several unit airbags 532 are fixedly installed between the linkage frame 524 and the airbag limiting plate 534. Through the interconnection of the inner cavities of the unit airbags 532 and their installation between the linkage frame 524 and the airbag limiting plate 534, they can jointly absorb and disperse the impact force, enhance the protection effect, and at the same time ensure that the unit airbags 532 are evenly compressed, thereby improving the stability and reliability of the overall buffering performance.

[0047] Furthermore, the anti-detachment block 533 is hexagonal prism in shape, and its volume is larger than that of the collar 515. Because the anti-detachment block 533 is hexagonal prism and its volume is larger than that of the collar 515, it can be firmly installed at the end of the device to prevent the guide post 531 and the unit airbag 532 from falling off when impacted, thus ensuring the integrity and safety of the device structure.

[0048] Furthermore, the linkage frame 524 is composed of a linkage disc and several linkage rods, wherein the several linkage rods are evenly fixedly installed on the outer circular surface of the linkage disc. The linkage frame 524, composed of a linkage disc and evenly fixed linkage rods, enhances structural stability and ensures that when subjected to impact, the linkage frame 524 can stably transmit force to the first elastic component 52 and the second elastic component 53, thereby achieving effective multi-level buffer protection.

[0049] In practical use, the working principle of this invention is as follows:

[0050] When using this bridge construction safety protection isolation device, construction workers will first use the base 2 and the ground nails equipped on it to firmly install the device in the construction area of ​​the bridge. This installation process not only ensures the stability of the device, but also facilitates the subsequent flexible splicing of the device with the splicing slot 3 on one side of the bracket 1 and the splicing block 4 on the other side according to the actual needs of the construction length, thereby increasing or decreasing the number of devices to adapt to construction areas of different lengths.

[0051] It is worth mentioning that the surface of the device is also specially coated with a fluorescent coating 527. This fluorescent coating can emit a bright light at night or in low-light environments, which greatly improves the visibility and recognition of the device, ensuring that people walking or working at night can clearly see the construction area, effectively avoiding safety hazards caused by accidentally entering the construction area.

[0052] When construction workers or people in the vicinity accidentally fall or bump into these isolation devices, they will first come into contact with the elastic mesh 526, which is an arc-shaped protrusion. This specially shaped elastic mesh is made of several stainless steel wires woven together, and has good elasticity and cushioning properties. When a person hits it, the elastic mesh 526 will immediately undergo elastic deformation, thereby absorbing and reducing part of the impact force, providing initial protection to the person who is hit.

[0053] As the impact continues to be transmitted, the first elastic component 52 begins to function. The linkage 524 moves backward upon impact, during which the diagonal bar 523 expands outward, pushing the slider 522 to slide outward along the base column 513. Simultaneously, the telescopic spring 521 connecting the slider 522 and the base column 513 is compressed, further weakening the impact and providing more protection for the impactor.

[0054] During this process, the second elastic component 53 also functions simultaneously. The guide post 531 on the linkage frame 524 moves stably backward under the limiting action of the collar 514. Several unit airbags 532 fixedly installed on the outer circular surface of the guide post 531 are compressed accordingly. The inner cavities of these unit airbags are interconnected, which can jointly absorb and disperse the impact force, further reducing the injury to the impactor.

[0055] Furthermore, once the elastic net 526, the telescopic spring 521, and the unit airbag 532 are compressed to a certain extent, they begin to recover. This recovery process generates an outward force that gently pushes the impactor into the device, thereby reducing the risk of the impactor colliding with the device again due to inertia and further improving the safety performance of the device.

[0056] In summary, this bridge construction safety protection isolation device, through its unique design and ingenious mechanism, not only achieves flexible adaptation to construction areas of different lengths, but also provides eye-catching signs and reminders at night. More importantly, it can provide multi-level buffering and force dissipation when personnel accidentally collide with the device, thereby greatly reducing the potential risk of injury to personnel.

[0057] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
