Description

Technical Field

[0001] This utility model relates to the technical field of railway guardrail steel structure, specifically a railway guardrail steel structure that is easy to assemble. Background Technology

[0002] Railway guardrail steel structures are important facilities specifically designed for safety protection along railway lines. Typically made of high-strength steel, they are sturdy and durable. Their scientifically designed structure effectively prevents runaway trains or pedestrians from entering, ensuring the safety and smooth operation of railway transportation. These guardrails not only have strong load-bearing capacity but can also adapt to various complex geographical environments, providing a reliable safety barrier whether on gentle plains or rugged mountains. Furthermore, railway guardrail steel structures possess excellent corrosion resistance and a long service life, reducing maintenance costs and making them an indispensable part of modern railway infrastructure.

[0003] The easily assembled railway fence steel structure adopts a modular design concept, breaking down the fence into standardized unit components, such as posts, beams, and connectors. These components are prefabricated in the factory, and during on-site installation, the various units can be quickly and securely assembled using simple bolts or clips. This greatly shortens the construction cycle and reduces installation difficulty, making it particularly suitable for emergency repairs or scenarios requiring frequent disassembly and relocation. Its structural design ensures sufficient strength and protection while also taking into account convenience, making the laying and maintenance of railway fences more efficient and flexible.

[0004] However, existing easily assembled railway guardrail steel structures, especially those using traditional fixed connections, require the guardrail length to be adjusted by replacing standard sections of different lengths. Furthermore, it's difficult to ensure perfectly synchronized movement of the support rods on both sides, which can easily lead to twisting or tilting after adjustment. Additionally, the guardrail's ability to resist deformation and maintain structural stability significantly decreases when facing lateral impacts from trains or strong winds, increasing the risk of damage or failure. Moreover, the guardrail has poor impact cushioning and lacks additional pre-tensioning to enhance the overall structural rigidity in static conditions. To address these issues, an easily assembled railway guardrail steel structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a railway guardrail steel structure that is easy to assemble, which solves the problems in the prior art of not being able to accurately and stably adjust the guardrail length, not being able to provide additional support, and not being able to resist eccentric loads.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily assembled railway guardrail steel structure, comprising two support rods, each support rod having a fixed plate fixedly connected to both ends on one side; a lead screw penetrating and rotatably connected to one side of each fixed plate on one side, the lead screw penetrating and rotatably connected to the support rod; a rotating rod penetrating and rotatably connected to the top and bottom of the inner wall of each support rod on one side, the rotating rod being fixedly connected to the lead screw; a synchronous pulley penetrating and fixedly connected to one end of the outer ring of each rotating rod; a synchronous belt being provided between the synchronous pulleys; and a synchronous belt being provided at the bottom of the rotating rod. A worm gear is fixedly connected to the other end of the outer ring of the moving rod. A transmission rod is rotatably connected to one end of the fixed plate on one side. A worm is fixedly connected to one end of the transmission rod, and the worm meshes with the worm gear. Nut pairs are threadedly connected to the outer ring of the lead screw, and the nut pairs are slidably connected to the other fixed plate. Bearing rods are fixedly connected to all four sides of the other side of the fixed plate on one side, and the bearing rods are slidably connected to the other fixed plate. An adjustment component is provided at the top of the bottom fixed plate, and a disassembly component is provided at the bottom of the support rod.

[0007] By adopting the above technical solution and through the linkage between the above structures, the guardrail can maintain a stable length after adjustment and will not easily change in length due to external forces, thus improving the reliability of the guardrail.

[0008] As a further description of the above technical solution: the adjustment component includes a connecting rod, which is rotatably connected to the top of the bottom fixed plate. One end of the connecting rod is slidably connected to a slide rod, which is rotatably connected to the top fixed plate. Each connecting rod has a first spring inside it, and one end of the first spring is fixedly connected to the slide rod.

[0009] By adopting the above technical solution, the linkage between the above components can provide additional support during the adjustment process, preventing the guardrail from deforming excessively during adjustment. At the same time, when the guardrail is subjected to external force, the spring can play a buffering role, further improving the guardrail's impact resistance.

[0010] As a further description of the above technical solution: the disassembly assembly includes a connecting block, which is fixedly connected to the bottom of the support rod, and a base is slidably connected through the bottom of the connecting block.

[0011] By adopting the above technical solution, the installed connecting block can support and fix the required fixing rod, and the installed base can place the overall structure in the designated position.

[0012] As a further description of the above technical solution: both sides of one end of the connecting block are slidably connected with a fixing rod, and the fixing rod is fixedly connected to the base. Both ends of the outer ring of the fixing rod are fitted with a second spring.

[0013] By adopting the above technical solution, the installed fixing rod can support and fix the required second spring, thereby driving the connecting block to slide on the base.

[0014] As a further description of the above technical solution: a slider is slidably connected through one side of the base, and a third spring is uniformly distributed inside the slider.

[0015] By adopting the above technical solution, the required third spring can be connected and fixed by the installed slider.

[0016] As a further description of the above technical solution: one end of each of the third springs is fixedly connected to a positioning rod, and the positioning rod is slidably connected to the slider.

[0017] By adopting the above technical solution, the installed positioning rod can be driven by a third spring, thereby allowing the positioning rod to slide within the slider.

[0018] As a further description of the above technical solution: the top side of the base is provided with sliding grooves at both ends, and the sliding grooves are in contact with the positioning rod.

[0019] By adopting the above technical solution, the positioning rod can be driven into the slider through the groove, thereby compressing the third spring.

[0020] As a further description of the above technical solution: the other end of the transmission rod is slidably connected to a rocker arm.

[0021] By adopting the above technical solution, the installed rocker arm allows the transmission rod to rotate on the support rod.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model provides an easy-to-assemble railway guardrail steel structure. Firstly, through the linkage between the transmission rod, worm gear, lead screw, rotating rod, worm wheel, synchronous pulley, synchronous belt, nut pair, connecting rod, sliding rod and first spring, the length of the guardrail can be finely adjusted according to actual needs, and the adjustment process of the two support rods is more coordinated and consistent. At the same time, it can provide additional support, enhance the overall load-bearing capacity of the guardrail, and thus further enhance the stability and safety of the guardrail.

[0024] This utility model provides an easy-to-assemble railway guardrail steel structure. Through the linkage between the fixed rod, the second spring, the connecting block, the slider, the slide groove, the third spring, and the positioning rod, it can prevent the impact force from being transmitted along the entire guardrail chain, avoiding damage to a wider area of ​​the guardrail. It also makes the guardrail system more adaptable to impact forces of different sizes and directions, and helps to distribute stress more evenly when subjected to force, avoiding stress concentration that could lead to localized damage.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figure 1 , Figure 2 and Figure 5This utility model discloses an easily assembled railway guardrail steel structure, comprising two support rods 1, which can support the required equipment. Both ends of one side of the support rod 1 are fixedly connected to a fixing plate 5, which can support and fix the required components and structures. The bottom of the connecting block 18 is slidably connected to a base 19, which can place the overall structure in a designated position. The other end of the transmission rod 2 is slidably connected to a rocker arm 3, which allows the transmission rod 2 to rotate on the support rod 1.

[0035] Reference Figure 2 and Figure 3 One side of the fixed plate 5 is rotatably connected to a lead screw 6, which is rotatably connected to the support rod 1. The top and bottom of the inner wall of the support rod 1 are rotatably connected to a rotating rod 7, which is fixedly connected to the lead screw 6. One end of the outer ring of the rotating rod 7 is rotatably connected to a synchronous pulley 9, and a synchronous belt 10 is provided between the synchronous pulleys 9. The other end of the outer ring of the bottom rotating rod 7 is rotatably connected to a worm gear 8. One end of the fixed plate 5 is rotatably connected to a transmission rod 2. One end of the transmission rod 2 is fixedly connected to a worm gear 4, which meshes with a worm wheel 8. The outer ring of the lead screw 6 is threaded with a nut assembly 11, which penetrates and slides through the other side of the fixed plate 5. Rotation of the transmission rod 2 causes the worm gear 4 to drive the worm wheel 8 to rotate on the support rod 1, thereby causing the bottom rotating rod 7 to rotate on the support rod 1. This causes the bottom synchronous pulley 9 to rotate on the support rod 1. Subsequently, through the transmission of the synchronous belt 10, the lead screw 6 rotates synchronously on the fixed plate 5, thus causing the nut assembly 11 to rotate. The support rods 1 slide on the fixed plate 5, ensuring the synchronization of the two support rods 1 during the adjustment process and avoiding deformation or damage to the guardrail due to asynchrony. Bearing rods 12 are fixedly connected to the other side of the fixed plate 5, and each bearing rod 12 is slidably connected to the other fixed plate 5. Adjustment components are provided at the top of the bottom fixed plate 5, and disassembly components are provided at the bottom of the support rods 1. The adjustment components include connecting rods 13, which are rotatably connected to the top of the bottom fixed plate 5. One end of each connecting rod 13 is slidably connected to a sliding rod 14, which is rotatably connected to the top fixed plate 5. Each connecting rod 13 has a first spring 15 inside, and one end of each first spring 15 is fixedly connected to the sliding rod 14. Through the sliding of the fixed plate 5 and the rotation of the sliding rod 14 and connecting rod 13, the sliding rod 14 slides on the connecting rod 13. Then, through the rebound of the first spring 15, the first spring 15 can act as a buffer when the guardrail is subjected to external force, further improving the guardrail's impact resistance.

[0036] Reference Figure 4 and Figure 5The disassembly assembly includes a connecting block 18, which is fixedly connected to the bottom of the support rod 1. A fixing rod 16 is slidably connected to both sides of one end of the connecting block 18, and the fixing rod 16 is fixedly connected to the base 19. A second spring 17 is sleeved on both ends of the outer ring of the fixing rod 16. By sliding the connecting block 18 on the base 19, the connecting block 18 slides on the fixing rod 16, thus compressing the second spring 17, providing a certain buffering effect and reducing the direct impact on the guardrail itself and the foundation below. A fixing rod 16 is slidably connected to both sides of one side of the base 19. The sliding connection includes a slider 20, and each slider 20 has a uniformly distributed third spring 22 inside. One end of each third spring 22 is fixedly connected to a positioning rod 23, and the positioning rod 23 is slidably connected to the slider 20. Both ends of the top side of the base 19 are provided with sliding grooves 21, and the sliding grooves 21 contact the positioning rods 23. By squeezing the positioning rods 23 through the sliding grooves 21, the positioning rods 23 slide into the slider 20, thereby squeezing the third springs 22 and causing the slider 20 to slide out of the base 19, thus reducing maintenance time and the impact on railway operations.

[0037] Working principle: A specified number of bases 19 are placed in a designated position. By allowing the positioning rod 23 to slide into the slider 20, the third spring 22 is compressed, causing the slider 20 to slide into the base 19. Subsequently, the rebound of the third spring 22 causes the positioning rod 23 to slide out of the slider 20 and into the groove 21, thus fixing and limiting two adjacent bases 19. Then, by sliding the support rod 1, the connecting block 18 slides on the base 19, causing the connecting block 18 to slide on the fixing rod 16, thereby compressing the second spring 17. The rebound of the second spring 17 provides a certain buffering capacity for the support rod 1. Subsequently, when the force on the support rod 1 or the base 19 is too large, the base 19 will slide, causing the groove 21 to compress the positioning rod 23, causing the positioning rod 23 to slide into the slider 20, thereby compressing the third spring 22, thus fixing and limiting the position of the base 19. Block 20 separates, thus separating the base 19 or support rod 1, which is subjected to greater force, from other guardrails. Then, through the rotation of transmission rod 2, worm 4 rotates on support rod 1. Subsequently, through the meshing connection between worm 4 and worm wheel 8, worm wheel 8 drives bottom rotating rod 7 to rotate on support rod 1, thereby causing bottom synchronous pulley 9 to rotate on support rod 1. Then, through the transmission of synchronous belt 10, top synchronous pulley 9 rotates synchronously, thereby causing top rotating rod 7 to rotate synchronously on support rod 1, thereby causing lead screw 6 to rotate synchronously on fixed plate 5, thereby driving nut pair 11 to slide on fixed plate 5 and being limited by bearing rod 12. Subsequently, through the mutual separation of fixed plates 5, connecting rod 13 and slide rod 14 rotate on fixed plate 5, thereby causing slide rod 14 to slide on connecting rod 13, and through the rebound of first spring 15, additional support force is provided to fixed plate 5.
