Description

Technical Field

[0001] This utility model relates to the field of transportation, and in particular to a road safety guardrail for transportation. Background Technology

[0002] An existing patent (publication number: CN218521680U) proposes a traffic collision safety guardrail, including a horizontal frame and uprights. A base box is fixedly connected to the bottom of each upright, and a weighted base is fixedly connected to the bottom of the base box. The uprights are hollow, and their bottoms communicate with the base box. A rotating disk is rotatably connected inside the base box, and a rotating column is fixedly connected to the upper part of the rotating disk. The rotating column is rotatably connected to the inner side of the uprights via a bearing. A torsion spring is provided between the bottom of the rotating disk and the inner side of the base box. Rotation slots are provided on both sides of the base box, and horizontal bars are fixedly connected to both sides of the rotating disk. However, the horizontal frame structure in this device is relatively fixed. When a section of the guardrail is damaged due to a collision, the entire horizontal frame needs to be replaced. It is not possible to quickly replace only the damaged section, increasing the guardrail maintenance cost and reducing its operational efficiency, thus presenting drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a dual buffer structure of anti-collision cylinders and anti-collision rings. This structure absorbs and buffers the impact force generated during vehicle collisions, reduces rigid contact between vehicles and guardrails, minimizes secondary injuries from traffic accidents, and allows for quick and individual replacement of damaged anti-collision cylinders, reducing maintenance costs and improving the operational efficiency of road safety barriers.

[0004] The objective of this utility model is achieved through the following technical solution: A road safety barrier includes a guardrail, a shaft, a crash cylinder, a locking block, a control rod, a rotating sleeve, and a drive gear. The guardrail has connecting ears on both sides, support legs at the bottom, and fixing plates on the support legs. The fixing plates are bolted to the ground. The lower side of the guardrail has a lower crossbar with multiple lower support sleeves. The upper side of the guardrail has an upper crossbar with multiple upper support sleeves on its lower side. The upper crossbar has an mounting groove that adapts to the mounting sleeves. The mounting sleeves connect to the mounting groove. The lower part of the mounting sleeve has a shaft that passes sequentially through the upper crossbar, upper support sleeves, crash cylinder, lower support sleeves, and lower crossbar. The crash cylinder rotates on the shaft. Multiple crash rings are connected to the outside of the crash cylinder, and reflective stickers are connected to the outside of the crash rings.

[0005] The upper crossbar of this utility model has multiple locking grooves on both sides, and the mounting sleeve has external through holes on both sides. The external through holes and locking grooves are adapted to the locking block. The outer end of the locking block is connected to the locking groove. The locking block passes through the mounting sleeve. The mounting sleeve has partitions on both sides. The inner side of the partitions is attached to the rotating sleeve. The rotating sleeve is connected to the control rod by screws. The screws are connected to the rotating sleeve and the control rod in sequence. Beneficial effects

[0006] When a vehicle collision occurs, the anti-collision cylinder converts the impact force into rotational kinetic energy by rotating around its axis, dispersing the local impact force. At the same time, multiple anti-collision rings on the outside of the anti-collision cylinder are made of elastic material, which can further absorb the collision energy and reduce the rigid contact between the vehicle and the guardrail. Furthermore, the reflective stickers added to the outside of the anti-collision rings can reflect light in both day and night environments, improving the visual warning effect of the guardrail on vehicles and reducing the accident rate at night and in severe weather, thus providing double protection for road traffic safety.

[0007] The meshing and linkage between the drive gear and driven gear of this utility model, in conjunction with the forward and reverse thread positioning between the control rod and the locking block, allows the locking blocks on both sides to move synchronously towards or away from each other by rotating the knob. The locking blocks are embedded in the locking groove, increasing the positioning fulcrum of the upper crossbar for the mounting bracket, thus ensuring stable support of the shaft. When the knob is rotated in the opposite direction to completely disengage the locking block from the locking groove, the shaft can be quickly pulled out of the guardrail by lifting it up, so that damaged anti-collision cylinders can be quickly replaced individually, avoiding the material waste caused by replacing the entire guardrail, shortening the guardrail maintenance time, and reducing operation and maintenance costs.

[0008] This utility model allows adjacent guardrails to be quickly spliced ​​together via connecting ears, adapting to different lengths of transportation roads, improving construction efficiency, reducing installation difficulty, and enabling quick locking and unlocking of the axle by rotating the knob. No special tools are required during the replacement and disassembly of the crash barrier, making operation convenient and improving the maintenance efficiency of traffic road crash barriers.

[0009] This utility model uses a dual buffer structure of anti-collision cylinder and anti-collision ring to absorb and buffer the impact force generated during vehicle collisions, reduce rigid contact between vehicles and guardrails, reduce secondary injuries from traffic accidents, and allow for quick and individual replacement of damaged anti-collision cylinders, reducing maintenance costs and improving the operation and maintenance efficiency of road guardrails.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A road safety guardrail includes a guardrail 01, a shaft 09, a crash cylinder 10, a locking block 15, a control rod 18, a rotating sleeve 19, and a drive gear 21. The guardrail 01 has connecting ears 02 on both sides, and a support leg 03 at its lower part. The support leg 03 has a fixing plate 04, which is bolted to the ground. The lower side of the guardrail 01 has a lower crossbar 06 with multiple lower support sleeves 08. The upper side of the guardrail 01 has an upper crossbar 05 with multiple upper support sleeves 07 on its lower side. The upper side of the upper crossbar 05 has a mounting groove 13 that adapts to the mounting sleeves 14, which are connected to the mounting groove 13. The lower part of the mounting sleeve 14 has a shaft 09 that passes through the upper crossbar in sequence. 05. Upper support sleeve 07, anti-collision cylinder 10, lower support sleeve 08, lower crossbar 06. The anti-collision cylinder 10 rotates on the shaft 09. Multiple anti-collision rings 11 are connected to the outside of the anti-collision cylinder 10. Reflective stickers 12 are connected to the outside of the anti-collision rings 11. When a vehicle collides, the anti-collision cylinder 10 converts the impact force into rotational kinetic energy by rotating around the shaft 09, dispersing the local impact force. At the same time, the multiple anti-collision rings 11 on the outside of the anti-collision cylinder 10 are made of elastic material, which can further absorb the collision energy and reduce the rigid contact between the vehicle and the guardrail. The reflective stickers 12 added to the outside of the anti-collision rings 11 can reflect light in both day and night environments, improve the visual warning effect of the guardrail on vehicles, reduce the accident rate at night and in bad weather, and provide double protection for the safety of traffic roads.

[0019] Example 2: The upper crossbar 05 of this utility model has multiple locking grooves 16 on both sides, and the mounting sleeve 14 has external through holes 17 on both sides. The external through holes 17 and locking grooves 16 are adapted to the locking block 15. The outer end of the locking block 15 is connected to the locking groove 16 and passes through the mounting sleeve 14. The mounting sleeve 14 has partitions 28 on both sides. The inner side of the partitions 28 is fitted with a rotating sleeve 19. The rotating sleeve 19 is connected to the control rod 18 by screws 20. The screws 20 are connected to the rotating sleeve 19 and the control rod 18 in sequence. Adjacent guardrails 01 can be quickly spliced ​​through connecting ears 02 to adapt to different lengths of transportation road scenarios, improve construction efficiency, reduce installation difficulty, and the shaft 09 can be quickly locked and unlocked by rotating the knob 24. During the replacement and disassembly of the anti-collision cylinder 10, no special tools are required, making the operation convenient and improving the maintenance efficiency of the anti-collision guardrail of the transportation road.

[0020] Example 3: The control rod 18 of this invention passes sequentially through the partition 28 and the rotating sleeve 19. Both ends of the control rod 18 are threadedly connected to locking blocks 15. The rotating sleeve 19 has a driven gear 22 on its exterior, which meshes with a drive gear 21. The drive gear 21 is connected to the driven gear 22. The meshing and linkage between the drive gear 21 and the driven gear 22, along with the forward and reverse threaded positioning between the control rod 18 and the locking blocks 15, allows the locking blocks 15 on both sides to be synchronously driven by rotating the knob 24. The components can be displaced in opposite directions or away from each other, and the locking block 15 is embedded in the locking groove 16. The upper crossbar 05 provides a positioning fulcrum for the mounting sleeve 14 to ensure stable support for the shaft 09. When the reverse rotation knob 24 drives the locking block 15 to completely disengage from the locking groove 16, the shaft 09 can be quickly pulled out from the guardrail 01 by lifting it up. This allows for the rapid and individual replacement of some damaged anti-collision cylinders 10, avoiding material waste caused by replacing the entire guardrail, shortening guardrail maintenance time, and reducing operation and maintenance costs.

[0021] Example 4: The driven gear 22 of this utility model has a pad 27, which fits against the inner side of the cover plate 23. The pad 27 has a drive rod 26, which is connected to the inside of the bearing 25. The bearing 25 is connected to the outside of the cover plate 23. The outer side of the cover plate 23 is fitted with a knob 24, which is connected to the drive rod 26. The lower part of the cover plate 23 is connected to the mounting sleeve 14. This device absorbs and buffers the impact force generated during vehicle collision through the double buffer structure of the anti-collision cylinder 10 and the anti-collision ring 11, reducing the rigid contact between the vehicle and the guardrail, reducing secondary injuries in traffic accidents, and allowing for quick and individual replacement of damaged anti-collision cylinders 10, reducing maintenance costs and improving the operation and maintenance efficiency of road anti-collision guardrails.

[0022] Example 5: Installation steps: First, assemble the mounting sleeve 14 structure. Place the rotating sleeve 19 into the mounting sleeve 14, ensuring its outer surface aligns with the inner surface of the partition 28. Then, insert the control rod 18 through the external through hole 17 into the mounting sleeve 14, passing through the partition 28 and rotating sleeve 19 in sequence, and securing it to the rotating sleeve 19 with screws 20. Next, insert the locking block 15 through the external through hole 17 into the mounting sleeve 14 and place it around the control rod 18. Position the control rod 18 at both ends through positive and negative threads to the locking blocks 15 on both sides. Then, place the drive gear 21 and knob 24 on the inner and outer sides of the cover plate 23, respectively, ensuring the pad 27 aligns with the cover plate 23. Embed the drive rod 26 into the bearing 25 and secure it to the knob 24. Finally, install the cover plate 23. The mounting bracket 14 is positioned on the upper part, and the drive gear 21 and driven gear 22 are meshed together. After the mounting bracket 14 structure is assembled, the guardrail 01 structure is then assembled. First, the anti-collision cylinder 10 is placed inside the guardrail 01, and the upper and lower sides of the anti-collision cylinder 10 are respectively attached to the upper bracket 07 and the lower bracket 08. Then, the shaft 09 is passed through the upper crossbar 05, the upper bracket 07, the anti-collision cylinder 10, the lower bracket 08, and the lower crossbar 06 in sequence until the mounting bracket 14 is embedded in the mounting groove 13, and the locking block 15 is aligned with the locking groove 16. Then, the locking blocks 15 on both sides are moved to their embedded locking groove 16 by rotating the knob 24. Then, the rotating shaft is passed through the connecting ear 02 of the adjacent guardrail 01 to splice multiple sets of guardrail 01. Finally, the fixing plate 04 is fixed to the ground with bolts to complete the installation.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
