Description

Technical Field

[0001] This invention relates to the field of traffic guardrail technology, specifically a collision-resistant road traffic guardrail. Background Technology

[0002] Traffic barriers are traffic safety facilities installed on the outer side of road shoulders, traffic dividers, and pedestrian curbs. They absorb collision energy by deforming themselves or allowing vehicles to climb, thereby changing the direction of travel, preventing vehicles from going off the road or entering oncoming lanes, and minimizing injury to occupants.

[0003] Currently, when a vehicle collides with a guardrail, the impact force is only buffered by springs or airbags installed on one side of the guardrail. There is no structure to distribute the buffering force to other areas, resulting in a concentrated impact force and poor protective effect. The guardrail is easily damaged, and due to the poor buffering effect, the driver is more likely to suffer serious injuries. Therefore, a new type of road safety guardrail is needed to solve these technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a collision-proof road traffic guardrail.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a road traffic guardrail with anti-collision features, including a support plate, an anti-collision plate fixedly connected to the top of the support plate, a buffer box fixedly connected to the rear side of the anti-collision plate, and a buffer structure provided on the top of the support plate;

[0006] The buffer structure includes an arc-shaped absorber plate 1 fixed to the front side of the support plate. Arc-shaped absorber plates 2 are fixed to both the front and rear sides of the interior of the arc-shaped absorber plate 1, and the other end of each arc-shaped absorber plate 2 is fixed to the anti-collision plate. The part connecting the anti-collision plate and the buffer box has a common opening. A spring 1 is fixed to the inner side of the arc-shaped absorber plate 1, and the rear end of the spring 1 is fixed to the rear side of the interior of the buffer box. A connecting rod is fixed to the front end of the inner side of each arc-shaped absorber plate 2, and a pulley is rotatably connected to the rear end of each connecting rod. Triangular plates are slidably connected to both the front and rear ends of the rear side of the interior of the buffer box. Dampers are fixed to both the front and rear sides of the bottom of the interior of the buffer box, and the top end of each damper contacts the bottom end of the triangular plate.

[0007] Preferably, the top of the buffer tank is provided with a cooling mechanism, which includes a water tank fixed to the top of the buffer tank. A sliding plate is slidably connected to the top of the water tank. A side plate is fixed to the bottom of the sliding plate near the side of the arc-shaped absorption plate. Sliding holes are provided at both the front and rear ends of the buffer tank away from the anti-collision plate. An L-shaped plate is fixed to the side of the triangular plate away from the anti-collision plate, and the L-shaped plate passes through the sliding hole. An L-shaped plate is fixed to the top of the L-shaped plate, and the bottom of the L-shaped plate is fixed to the sliding plate. A set of cooling pipes is fixed to the side of the water tank near the anti-collision plate. A set of through holes is provided on the surface of the side plate.

[0008] Preferably, a fixing plate is fixedly connected to the bottom end of the support plate, and mounting holes are provided at the four corners of the top end of the fixing plate.

[0009] Preferably, reinforcing rods are fixedly connected to both the front and rear ends of the rear side of the anti-collision plate, and the bottom ends of the reinforcing rods are fixedly connected to the top end of the fixed plate.

[0010] Preferably, an inclined internally threaded pipe is fixedly connected to the top of the rear side of the water tank, and a sealing cap is threadedly connected to the top of the internally threaded pipe.

[0011] Preferably, a transparent observation box is fixedly connected to the rear side of the water tank, and the transparent observation box is in communication with the water tank.

[0012] Preferably, each of the triangular plates has a second spring fixedly connected to its bottom end, and the bottom end of each second spring is fixedly connected to the bottom end of the buffer box.

[0013] Beneficial effects:

[0014] Compared with existing technologies, this crash barrier for road traffic has the following advantages:

[0015] I. This invention uses a pair of arc-shaped absorber plates to initially buffer the impact force. When the first arc-shaped absorber plate deforms, the first spring is compressed, further buffering the impact force. Then, when the second arc-shaped absorber plate is impacted, it deforms, thus absorbing and buffering the impact force. After the second arc-shaped absorber plate is impacted, its front end bends and deforms backward, the connecting rod moves backward, and the connecting rod drives the pulley to move backward. The pulley presses against the triangular plate, and the triangular plate slides downward, pressing against the damper. At this time, the impact force is dispersed downward, and the damper buffers the impact force. Therefore, this structure is conducive to multiple buffering and dispersion of the impact force, greatly improving the buffering effect of the guardrail, preventing the guardrail from being damaged, and the good buffering performance helps to reduce the injury to the driver.

[0016] II. Upon impact, the present invention causes the triangular plate to move downwards, which in turn causes the L-shaped plate one to slide downwards within the sliding hole. The L-shaped plate one then causes the L-shaped plate two to move downwards, which in turn causes the sliding plate to move downwards. The sliding plate then causes the side plate to move downwards simultaneously. As the side plate moves downwards, the through hole gradually aligns with the cooling pipe. At this time, the cold water inside the water tank enters the cooling pipe through the through hole and is then sprayed onto the impacted area. Furthermore, due to the sliding plate sliding down, the cold water is squeezed, causing it to spray out of the cooling pipe quickly. This accelerates the flow rate of the cold water, thereby helping to cool the impacted area and preventing spontaneous combustion caused by the impact. Attached Figure Description

[0023] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0024] like Figures 1-5As shown, a crash barrier for road traffic includes a support plate 1, with a crash barrier 2 fixedly connected to the top of the support plate 1. A fixing plate 6 is fixedly connected to the bottom of the support plate 1, and mounting holes 7 are provided at the four corners of the top of the fixing plate 6. The design of the mounting holes 7 facilitates the fixing of the barrier. Reinforcing rods 8 are fixedly connected to both the front and rear ends of the rear side of the crash barrier 2, and the bottom ends of the reinforcing rods 8 are fixedly connected to the top of the fixing plate 6. The reinforcing rods 8 help to enhance the load-bearing capacity of the barrier. A buffer box 3 is fixedly connected to the rear side of the crash barrier 2, and a buffer structure 4 is provided on the top of the support plate 1.

[0025] The buffer structure 4 includes an arc-shaped absorber plate 40 fixed to the front of the support plate 1. Arc-shaped absorber plates 41 are fixed to both the front and rear sides of the arc-shaped absorber plate 40, and the other end of each arc-shaped absorber plate 41 is fixed to the anti-collision plate 2. The connection between the anti-collision plate 2 and the buffer box 3 has a common opening 42. A spring 43 is fixed to the inner side of the arc-shaped absorber plate 40, and the rear end of the spring 43 is fixed to the rear side of the buffer box 3. A connecting rod 44 is fixed to the front end of the inner side of each arc-shaped absorber plate 41, and a pulley 45 is rotatably connected to the rear end of each connecting rod 44. Triangular plates 46 are slidably connected to both the front and rear ends of the rear side of the buffer box 3. A spring 12 is fixed to the bottom end of each triangular plate 46, and the bottom end of each spring 12 is fixed to the bottom end of the buffer box 3. The spring 12 further enhances the buffering and energy absorption function and, after impact, can cooperate with the damper 47 to return the triangular plate 46 to its original position. Dampers 47 are fixed to both the front and rear sides of the bottom of the buffer box 3, and the top of each damper 47 is in contact with the bottom of the triangular plate 46.

[0026] During operation, the first arc-shaped absorber plate 40 is impacted first, and it buffers the impact force. The first arc-shaped absorber plate 40 deforms, compressing the first spring 43, which further buffers the impact force. Then, the two second arc-shaped absorber plates 41 are impacted and deform, absorbing and buffering the impact force. After impact, the front end of the second arc-shaped absorber plate 41 bends backward, causing the connecting rod 44 to move backward. The connecting rod 44 drives the pulley 45 to move backward, and the pulley 45 compresses the triangular plate 46. The triangular plate 46 slides downward and compresses the damper 47, dispersing the impact force downward. The damper 47 further buffers the impact force. This structure effectively provides multiple buffers and disperses the impact force, greatly improving the buffering effect of the guardrail, preventing damage, and reducing driver injury due to its excellent buffering properties.

[0027] The top of the buffer tank 3 is equipped with a cooling mechanism 5, which includes a water tank 51 fixedly attached to the top of the buffer tank 3. An inclined internally threaded pipe 9 is fixedly attached to the top rear side of the water tank 51, and a sealing cap 10 is threadedly connected to the top of the internally threaded pipe 9. The design of the internally threaded pipe 9 facilitates the addition of cold water to the water tank 51, and the sealing cap 10 seals the water tank 51. A transparent observation box 11 is fixedly attached to the rear side of the water tank 51 and is connected to the water tank 51. When adding cold water, the water is stopped after the cold water enters the transparent observation box 11. The top of the water tank 51 is slidably connected to a sliding plate 52. The bottom of the sliding plate 52 is fixed to a side plate 53 near the side of the arc-shaped absorption plate 40. The buffer box 3 has sliding holes 54 at both ends on the side away from the anti-collision plate 2. The side of the triangular plate 46 away from the anti-collision plate 2 is fixed to an L-shaped plate 55, and the L-shaped plate 55 passes through the sliding hole 54. The top of the L-shaped plate 55 is fixed to an L-shaped plate 56, and the bottom of the L-shaped plate 56 is fixed to the sliding plate 52. A set of cooling pipes 57 is fixed to the side of the water tank 51 near the anti-collision plate 2. A set of through holes 58 is opened on the surface of the side plate 53.

[0028] During operation, upon impact, the triangular plate 46 moves downward, causing the L-shaped plate 55 to slide downward within the sliding hole 54. The L-shaped plate 55 then causes the L-shaped plate 56 to move downward, which in turn causes the sliding plate 52 to move downward. The sliding plate 52 then causes the side plate 53 to move downward simultaneously. As the side plate 53 moves downward, the through hole 58 gradually aligns with the cooling pipe 57. At this point, the cold water inside the water tank 51 enters the cooling pipe 57 through the through hole 58 and is then sprayed onto the impacted area. Furthermore, due to the sliding plate 52 sliding down, it compresses the cold water, causing it to spray out of the cooling pipe 57 rapidly. This accelerates the flow of the cold water, thus helping to cool the impacted area and preventing spontaneous combustion caused by the impact.

[0029] Working principle: The arc-shaped absorber plate 40 is impacted first, and it buffers the impact force. The arc-shaped absorber plate 40 deforms, compressing the spring 43, which further buffers the impact force. Then, the two arc-shaped absorber plates 41 are impacted and deform, absorbing and buffering the impact force. After impact, the front end of the arc-shaped absorber plate 41 bends backward, causing the connecting rod 44 to move backward. The connecting rod 44 drives the pulley 45 to move backward, and the pulley 45 compresses the triangular plate 46. The triangular plate 46 slides downward and compresses the damper 47. At this time, the impact force is dispersed downward, and the damper 47 buffers the impact force. This structure effectively provides multiple buffering and dispersion of the impact force, greatly improving the buffering effect of the guardrail, preventing damage to the guardrail, and its good buffering properties help reduce the injury to the driver.

[0030] Upon impact, the triangular plate 46 moves downward, causing the L-shaped plate 55 to slide downward within the sliding hole 54. The L-shaped plate 55 then causes the L-shaped plate 56 to move downward, which in turn causes the sliding plate 52 to move downward. The sliding plate 52 then causes the side plate 53 to move downward simultaneously. As the side plate 53 moves downward, the through hole 58 gradually aligns with the cooling pipe 57. At this point, the cold water inside the water tank 51 enters the cooling pipe 57 through the through hole 58 and is then sprayed onto the impacted area. Furthermore, due to the sliding plate 52 sliding down, it compresses the cold water, causing it to spray out of the cooling pipe 57 rapidly. This accelerates the flow of the cold water, thus helping to cool the impacted area and preventing spontaneous combustion caused by the impact.
