Description

Technical Field

[0001] This utility model relates to the field of highway construction safety protection technology, and more specifically, to a collision-resistant highway construction guardrail. Background Technology

[0002] During highway construction, guardrails are an important safety facility. Installing guardrails around construction sections effectively prevents vehicles from accidentally entering the construction area, avoiding collisions with construction equipment and personnel, and reducing the probability of traffic accidents.

[0003] Patent CN212200180U discloses a guardrail for highway construction. It utilizes a buffer spring fitted onto a sleeve, with a crash barrier installed at the outer end of the sleeve. The buffer spring is located between the base plate and the crash barrier. Upon impact, it reduces the impact on the crash barrier, providing protection. Since the buffer spring connects to the base plate and the crash barrier at both ends, and the base plate is fixed to the post and then to the ground via a base, the base plate is fixed in place. Upon impact, the crash barrier moves to one side with the spring, creating a buffer. However, when the impact subsides, the crash barrier returns to its original position with the spring. Due to the elasticity of the spring, the crash barrier will sway back and forth for a period of time. Since the crash barrier itself has weight, this swaying may damage the sleeve. Utility Model Content

[0014] Furthermore, the sleeve plate is U-shaped, the groove in the middle of the sleeve plate is engaged with the back plate, and the connecting sections on both sides of the sleeve plate are detachably connected to the railing.

[0015] Furthermore, the top of the upper anti-collision plate is provided with a first connecting hole, which is adapted to the connecting hole of the upper connecting ear; the bottom end is provided with two spaced upper connecting sleeves, each of which is provided with a second connecting hole for rotatably connecting the elastic anti-collision plate.

[0016] The top end of the upper anti-collision plate is rotatably connected to the upper connecting lug via an upper screw, and the bottom end is rotatably connected to the elastic anti-collision plate via a middle screw.

[0017] Furthermore, the bottom end of the lower anti-collision plate is provided with a third connecting hole, which is adapted to the connecting hole of the lower connecting lug; the top end is provided with two spaced lower connecting sleeves, and the lower connecting sleeves are provided with a fourth connecting hole for rotatably connecting the elastic anti-collision plate.

[0021] Furthermore, reflective strips are affixed to the outer sides of the upper and lower anti-collision plates.

[0022] Furthermore, the width of the base plate is greater than the width of the back plate, and the width of the base plate is also greater than the width of the support plate.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

Both the upper and lower impact plates are rotatably connected to a flexible impact plate via two central screws. When impacted, the upper or lower impact plate rotates inward around the upper or lower screw, causing the flexible impact plate to tensile and deform, thus providing cushioning. The flexible impact plate is made of rubber, which has good elasticity and flexibility, effectively buffering impacts.

[0025] Furthermore, in each anti-collision unit, its outer frame is detachably mounted on the guardrail via a sleeve plate, making it easy to remove and replace if an anti-collision unit is damaged. Attached Figure Description

[0041] 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.

[0042] like Figures 1-3 As shown, this embodiment provides a crash-resistant highway construction guardrail, including guardrail panels 1 arranged at intervals and several crash protection units detachably installed on the guardrail panels 1, with each crash protection unit equally spaced. Each crash protection unit includes an outer frame 2, an upper crash protection plate 3, a lower crash protection plate 4, and an elastic crash protection plate 5. The outer frame 2 is installed on the guardrail panel 1 and is U-shaped. The outer frame 2 is detachably installed on the guardrail panel 1 via a sleeve plate 6. The two ends of the outer frame 2 are rotatably connected to the upper crash protection plate 3 and the lower crash protection plate 4, and the upper crash protection plate 3 and the lower crash protection plate 4 are rotatably connected to the elastic crash protection plate 5.

[0043] In this embodiment, as Figures 5-7 As shown, the outer frame 2 includes a base plate 21, a back plate 22, and a top plate 23. The base plate 21 has positioning holes 211 for fixing to the ground. The top of the back plate 22 is fixed to the top plate 23, and the free end of the top plate 23 is fixed with an upper connecting lug 24 for rotatably connecting to the upper anti-collision plate 3. The bottom of the back plate 22 is fixed to the base plate 21, and the free end of the base plate 21 is fixed with a lower connecting lug 25 for rotatably connecting to the lower anti-collision plate 4.

[0044] Specifically, the outer frame 2 is also provided with auxiliary anti-collision plates 26, which are arc-shaped and whose two ends are fixed to the side of the back plate 22 facing the upper connecting ear 24 and the lower connecting ear 25. The outer frame 2 is also provided with inclined support plates 27, one end of which is fixed to the back plate 22 and the other end is fixed to the upper connecting ear 24 or the lower connecting ear 25, which can further support the frame. The width of the bottom plate 21 is greater than the width of the back plate 22, and at the same time, the width of the bottom plate 21 is greater than the width of the support plate 27, which facilitates the fixing of the bottom plate 21 to the ground.

[0045] In this embodiment, as Figures 1-4 As shown, each outer frame 2 is detachably fixed to the railing 1 by a sleeve plate 6. Specifically, the sleeve plate 6 is U-shaped, with a groove 61 in the middle of the sleeve plate 6 engaging with the back plate 22, and connecting sections 62 on both sides of the sleeve plate 6 detachably connected to the railing 1. The connecting section 62 has a first fixing hole 621, and correspondingly, the railing 1 has a second fixing hole 11. Bolts are passed through the corresponding first fixing hole 621 and second fixing hole 11 to fit the sleeve plate 6 onto the railing 1. More specifically, the railing 1 also has threaded holes 12, and the corresponding back plate 22 also has threaded holes. Bolts are passed through the threaded holes of the railing 1 and the back plate 22 to further fix the outer frame 2 to the railing 1, increasing the overall structural strength.

[0046] In this embodiment, the top of the upper anti-collision plate 3 is provided with a first connecting hole 31, which is adapted to the connecting hole of the upper connecting lug 24. Two spaced-apart upper connecting sleeves 32 are provided at the bottom of the upper anti-collision plate 3. Each upper connecting sleeve 32 has a second connecting hole 33 for rotatably connecting the elastic anti-collision plate 5. The top of the upper anti-collision plate 3 is rotatably connected to the upper connecting lug 24 via an upper screw 7, and the bottom of the upper anti-collision plate 3 is rotatably connected to the elastic anti-collision plate 5 via a middle screw 8.

[0047] The bottom end of the lower anti-collision plate 4 has a third connecting hole 41, which is adapted to the connecting hole of the lower connecting lug 25; the top end of the lower anti-collision plate 4 has two spaced lower connecting sleeves 42, each with a fourth connecting hole 43 for rotatably connecting the elastic anti-collision plate 5. The bottom end of the lower anti-collision plate 4 is rotatably connected to the lower connecting lug 25 via the lower screw 9, and the top end is rotatably connected to the elastic anti-collision plate 6 via the middle screw 8.

[0048] The curved plate of the elastic anti-collision plate 5 is made of rubber. Both ends of the elastic anti-collision plate 5 are respectively provided with intermediate connecting sleeves 51. The upper intermediate connecting sleeve 51 is located between the two upper connecting sleeves 32 of the upper anti-collision plate 3, and the lower intermediate connecting sleeve 51 is located between the two lower connecting sleeves 42 of the lower anti-collision plate 4. The intermediate connecting sleeve 51 has a fifth connecting hole 52. When the upper anti-collision plate 3 or the lower anti-collision plate 4 is impacted, the upper screw 7 of the upper anti-collision plate 3 rotates axially inward, or the lower screw 9 of the lower anti-collision plate 4 rotates axially inward; under the rotation of the upper anti-collision plate 3 or the lower anti-collision plate 4, the elastic anti-collision plate 5 is stretched and deformed, such as... Figure 6 As shown, this provides a buffer against impact.

[0049] In this embodiment, reflective strips 10 are also affixed to the outer sides of the upper anti-collision plate 3 and the lower anti-collision plate 4, which can reflect light at night or in low visibility environments, serving as a warning.

[0050] The anti-collision highway construction guardrail provided in this embodiment is equipped with multiple anti-collision units for buffering and protection against impacts. In each anti-collision unit, its outer frame 2 is detachably mounted on the guardrail panel 1 via a sleeve plate 6, allowing for easy removal and replacement if any anti-collision unit is damaged.

[0051] The upper anti-collision plate 3 is rotatably connected to the upper connecting lug 24 of the outer frame 2 via the upper screw 7, and the lower anti-collision plate 4 is rotatably connected to the lower connecting lug 25 of the outer frame 2 via the lower screw 9. Simultaneously, the upper and lower anti-collision plates 3 and 4 are rotatably connected to the elastic anti-collision plate 5 via two middle screws 5. When a vehicle accidentally hits the guardrail, the upper anti-collision plate 3 or the lower anti-collision plate 4 will rotate inward around the upper screw 7 or the lower screw 9, causing the elastic anti-collision plate 5 to undergo tensile deformation, thus providing a buffering effect. After the impact, the elastic restoring force of the elastic anti-collision plate 5 will cause it to return to its initial position. The upper and lower anti-collision plates 3 and 4 are rotatably connected to the outer frame 2 and also rotatably connected to the elastic anti-collision plate 5. During an impact, the deformation of the elastic anti-collision plate 5 provides buffering. After the impact, the elastic restoring force of the elastic anti-collision plate 5 will cause it to slowly return to its initial position, reducing and preventing damage during the plate's reset process.

[0052] The elastic bumper 5 is made of rubber, which has good elasticity and flexibility, and can effectively buffer impacts. When the bumper is impacted, the elastic bumper cushions the impact through its own tensile deformation.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
