Description
Technical Field
[0001] This utility model relates to the technical field of highway barrier facilities, and in particular to a flexible highway barrier device. Background Technology
[0002] Highways are closed road systems designed specifically for high-speed traffic. Their core features include full-line access control, lane separation, and central isolation. They aim to achieve efficient and safe vehicle passage by optimizing road conditions and traffic management. As a key component of the highway safety system, barrier devices exist because of the rigid requirements for accident prevention, risk control, and emergency response.
[0003] A search revealed that Chinese patent CN219653611U discloses a collision buffer device for highways. Traditional devices, due to their excessive grip, weaken the buffering effect on vehicles, reducing the protection for the vehicle and its occupants in the event of a traffic accident. This contradicts the original design purpose of protecting lives. Therefore, by installing a collision plate, upon impact, the plate is first cushioned by a strong spring. Simultaneously, the connecting rod and pressure plate move backward, compressing the air reservoir. This causes the air reservoir to supply air to the buffer cushion through an air pipe, rapidly expanding the cushion and applying a reverse thrust to the vehicle. Through the mutual cancellation of forces, the impact is reduced.
[0004] The aforementioned buffer devices utilize springs for cushioning, but since the springs are located on the outside and in contact with the external environment, they are easily covered by dust and impurities, which can corrode the springs and reduce their lifespan. Traditionally, when installing barriers on both sides of highways, some devices are simple curved plastic materials, which have a weak blocking effect. Other devices are rigid curved railings, which are made of hard materials. Although they are easy to stop when a vehicle is hit, the rigid railings are in contact with the vehicle and can easily cause damage due to the impact force. Furthermore, the railings can easily penetrate the vehicle's exterior and insert into the interior, potentially causing injury to people inside. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible barrier device for highways.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flexible barrier device for highways, comprising two hollow shells, wherein a buffer assembly is provided inside the hollow shells; The buffer assembly includes multiple limiting posts, which are fixedly connected to the inner wall of the hollow shell. A circular plate is fixedly connected to one end of each limiting post. A buffer block is slidably connected inside the hollow shell. The buffer block has multiple cylindrical holes inside. Multiple buffer springs are fixedly connected to one side of the buffer block. A rubber frame is provided on one side of the hollow shell, and a rubber pad is provided on one side of the buffer block.
[0007] As a further description of the above technical solution: The buffer springs are fixedly connected to one side of the inner wall of the hollow shell, the rubber pad has multiple friction grooves on one side, and the circular plate is slidably connected to the inside of the cylindrical hole.
[0008] As a further description of the above technical solution: Multiple fixing rings are fixedly connected to one side of the hollow shell, and multiple elastic ropes are arranged between two hollow shells. Both ends of the elastic ropes are fixedly connected to connecting rings, and the connecting rings are arranged inside the fixing rings.
[0009] As a further description of the above technical solution: One of the hollow shells is provided with a splicing component on one side, the splicing component including two insert frames, the two insert frames being fixedly connected to one side of the hollow shell.
[0010] As a further description of the above technical solution: Two insert blocks are fixedly connected to one side of the other hollow shell. Two insertion holes are opened inside the insert blocks. A U-shaped frame runs through the interior of the two insert frames. Two square grooves are opened on one side of the U-shaped frame.
[0011] As a further description of the above technical solution: A fixed shell is fixedly connected to the lower surface of one of the insert frames, a sliding plate is slidably connected inside the fixed shell, a U-shaped plate is provided on one side of the fixed shell, and multiple pull posts are fixedly connected between the U-shaped plate and the sliding plate, with the multiple pull posts slidably connected to one side of the fixed shell.
[0012] As a further description of the above technical solution: Multiple compression springs are fixedly connected between the sliding plate and one side of the inner wall of the fixed shell, and two blocks are fixedly connected to one side of the sliding plate.
[0013] This utility model has the following beneficial effects: 1. This utility model, through the setting of the buffer component, when the vehicle hits the hollow shell, the buffer block will retract into the hollow shell under the impact force, forming a buffer force. Combined with the elastic potential energy of the rubber frame and rubber pad, it helps to reduce the damage to the vehicle. At the same time, the friction texture helps to increase the friction between the vehicle and the rubber pad, which helps to decelerate the vehicle. In addition, the multiple interlaced elastic ropes help to stretch the elastic ropes into an arc shape when the vehicle hits the elastic ropes. Under the action of elasticity, the elastic ropes rebound after being stretched, which helps to absorb part of the impact force of the vehicle hitting the elastic ropes, thereby blocking and buffering.
[0014] 2. This utility model, through the setting of splicing components, utilizes the interlocking of the insert frame and the limiting of the U-shaped frame to facilitate the splicing of multiple blocking devices into a whole. This allows multiple spliced blocking devices to be subjected to force simultaneously when a vehicle collides with a single blocking device, thus dispersing the impact force and helping to increase the buffering and blocking effect on the vehicle.

[0017] 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.
[0018] As attached Figure 1-7 As shown, one embodiment of this utility model is provided: a flexible barrier device for highways, comprising two hollow shells 1, with a buffer assembly disposed inside the hollow shell 1; The buffer assembly includes multiple limiting posts 2, which are fixedly connected to the inner wall of the hollow shell 1. One end of each limiting post 2 is fixedly connected to a circular plate 3 that matches the inner diameter of the cylindrical hole 5. A buffer block 4 that directly receives the impact force is slidably connected inside the hollow shell 1. The buffer block 4 has multiple cylindrical holes 5 inside. Multiple buffer springs 6 for absorbing the impact force are fixedly connected to one side of the buffer block 4. A rubber frame 7 for auxiliary buffering is provided on one side of the hollow shell 1. A rubber pad 8 is provided on one side of the buffer block 4. The rubber elastic potential energy of the rubber pad 8 facilitates further buffering and protection of the buffer block 4.
[0019] As attached Figure 3 As shown, multiple buffer springs 6 are fixedly connected to one side of the inner wall of the hollow shell 1, and the circular plate 3 is slidably connected inside the cylindrical hole 5. The circular plate 3 plays a limiting role for the buffer block 4.
[0020] As attached Figure 1 As shown, one side of the rubber pad 8 is provided with multiple friction patterns 9 to increase friction and reduce speed.
[0021] As attached Figure 4 As shown, a plurality of fixing rings 10 for mounting connecting rings 11 are fixedly connected to one side of the hollow shell 1. A plurality of elastic ropes 12 for buffering are arranged between the two hollow shells 1. The multiple elastic ropes 12 are staggered and the two ends of the elastic ropes 12 are fixedly connected to the connecting rings 11. The connecting rings 11 are located inside the fixing rings 10 and can move inside the fixing rings 10.
[0022] As attached Figure 2 As shown, a splicing assembly is provided on one side of one of the hollow shells 1. The splicing assembly includes two U-shaped insert frames 13, and holes for the U-shaped frame 16 to pass through are opened on both sides of the insert frames 13. The two insert frames 13 are fixedly connected to one side of one of the hollow shells 1, and two insert blocks 14 are fixedly connected to one side of the other hollow shell 1. The insert blocks 14 are spliced with the insert frames 13 to facilitate the splicing of two adjacent devices. The insert blocks 14 have two insertion holes 15 inside for the U-shaped frame 16 to pass through.
[0023] As attached Figure 6 As shown, a U-shaped frame 16 runs through the interior of the two insert frames 13, and two square slots 17 are provided on one side of the U-shaped frame 16. As attached Figure 7 As shown, a fixed shell 18 for protecting the internal structure is fixedly connected to the lower surface of one of the insert frames 13. One side of the fixed shell 18 has a slot for sliding the pull post 21, and the other side has a through slot for sliding the block 22. The interior of the fixed shell 18 is slidably connected to a sliding plate 19 for connecting the block 22 and the pull post 21. A U-shaped plate 20 for pulling is provided on one side of the fixed shell 18. Multiple pull posts 21 are fixedly connected between the U-shaped plate 20 and the sliding plate 19. Multiple pull posts 21 are slidably connected to one side of the fixed shell 18. Multiple compression springs 23 are fixedly connected between the sliding plate 19 and one side of the inner wall of the fixed shell 18. The compression springs 23 are sleeved on the outside of the pull post 21. Two blocks 22 for engaging with the square slot 17 are fixedly connected to one side of the sliding plate 19.
[0024] Working principle: When multiple parts of a single blocking device consisting of two hollow shells 1, a buffer block 4, and an elastic rope 12 are spliced together, the insert block 14 of another blocking device is first inserted into the insert frame 13. After it is fully inserted, the insertion hole 15 in the insert block 14 will be aligned with the hole in the insert frame 13. Then, the U-shaped plate 20 is pulled. With the connection of the pull column 21 and the sliding plate 19, the block 22 will be driven to slide into the interior of the fixed shell 18. At this time, the compression spring 23 will be compressed and deformed, so that the bottom of the bottom insert frame 13 is released from obstruction. After the U-shaped frame 16 is inserted through the hole and through the insertion hole 15, when the U-shaped frame 16 is fully inserted, the square groove 17 is positioned directly above the square block 22. Then, the U-shaped plate 20 is released, so that the block 22 can be pushed into the square groove 17 by the spring-loaded sliding plate 19 after being compressed by the multiple compression springs 23. This will lock the U-shaped frame 16 in place and fix it in place, thus facilitating the splicing. After splicing, the bottom of the hollow shell 1 can be fixed to both sides of the highway. When a vehicle hits the device, if it hits the elastic rope 12, the elastic rope 12 will deform under the force and be pushed out by the vehicle to form an arc shape. The vehicle will be squeezed by the interlaced elastic ropes 12 in stages. During the squeezing process, the vehicle will be wrapped around it, which will help to gradually reduce the impact force and stop the vehicle. After the elastic rope 12 deforms, it will rebound and push the vehicle back, which will help to pull back the out-of-control vehicle and gradually stabilize the vehicle. When a vehicle collides with the hollow shell 1, it will first come into contact with the rubber pad 8, and then squeeze the rubber pad 8 and then the buffer block 4, causing the buffer block 4 to slide inside the hollow shell 1. At the same time, the circular plate 3 will slide inside the cylindrical hole 5 when the buffer block 4 moves. Meanwhile, the buffer block 4 will squeeze the buffer spring 6 when it moves, and the buffer spring 6 will be compressed and deformed, and then rebound to push the buffer block 4 back, which helps to cushion the vehicle. When the vehicle comes into contact with the rubber pad 8, it will come into contact with the friction pattern 9, which increases the friction force and reduces the vehicle speed, further cushioning and protecting the vehicle.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
