[0033] More specifically, when the equipment is damaged by impact, the guardrail can be replaced. The bolts on the fixing plate 9 are removed, the fixing plate 9 is taken off, exposing the mounting groove 7. The insert plate 8 is removed from the mounting groove 7, allowing the insert plate 8, along with the support rod 5, to leave the buffer frame 2. The bolts connecting the buffer frame 2 and the connecting plate 10 are removed, allowing the buffer frame 2 to be removed. Alternatively, the bolts in the middle of the connecting plate 10 are removed, separating the connecting plate 10 from the connecting block 11, allowing the buffer frame 2 to be removed. The above steps are repeated in reverse to assemble the guardrail equipment for replacing the guardrail structure. Through the combined structure, the equipment is divided into three main parts: the guardrail frame 1, the buffer frame 2, and the support rod 5. Depending on the specific damage to the equipment during impact, only the damaged specific structure needs to be replaced; the entire equipment does not need to be replaced.
[0034] Please see Figure 1 and Figure 2 As one implementation method for preventing climbing: the upper end of the buffer frame 2 is provided with a rotating groove 12, and a rotating shaft 13 is fixedly connected to the rotating groove 12. The axis of the rotating shaft 13 is flush with the outer end face of the buffer frame 2. A contact roller 14 is provided on the rotating shaft 13, and the contact roller 14 cooperates with the rotating groove 12.
[0035] Specifically, the contact roller 14 is positioned on the upper end of the buffer frame 2 by means of the rotating shaft 13. The rotational setting allows the outer end of the contact roller 14 to fit more closely with the rotating groove 12, reducing the gap between the contact roller 14 and the buffer frame. If someone wants to climb the guardrail, they need to rely on the uppermost end of the buffer frame 2 as a support point. When the climber comes into contact with the contact roller 14, the contact roller 14 will rotate along the rotating shaft 13 due to the force, thereby causing the climber's hand to detach from the contact roller 14 and lose its leverage point, thus avoiding the dangerous climbing behavior.
[0036] Please see Figure 3 As a further embodiment of the support rod: the support rod 5 includes an extension rod 15 and a rotating rod 16. The extension rod 15 is disposed at both ends of the rotating rod 16 and connected to the mounting plate 8. The rotating rod 16 cooperates with the buffer bucket 6 and is disposed on the outside of the buffer frame 2.
[0037] Specifically, the extension rod 15 supports the rotating rod 16 to extend out of the buffer frame, supporting the buffer tank 6 to contact the external vehicle, thus preventing the vehicle from directly impacting the buffer frame 2 during an impact. The impact is borne sequentially by the support rod 5 and the buffer frame.
[0038] Please see Figures 1-3 As a further embodiment of the buffer bucket: the outer end of the buffer bucket 6 is provided with a buffer sleeve 17.
[0039] Specifically, the buffer barrel 6 is protected by the buffer sleeve 17 to avoid damage due to external factors, and when a vehicle collides, the buffer barrel 6 is in contact with the vehicle through the buffer sleeve 17, further providing buffering capacity and reducing damage caused by impact.
[0040] Please refer to Figures 3-5 As a further embodiment of the buffer frame, a pressing rod 18 is arranged inside the buffer frame 2, one end of the pressing rod 18 is provided with a supporting slide rod 19, and a sliding opening 20 is formed in the guardrail frame 1, and the supporting slide rod 19 is in sliding fit with the sliding opening 20.
[0041] Specifically, the supporting slide rod 19 is connected with the sliding opening 20 through the pressing rod 18, and the supporting effect is provided by the supporting slide rod 19 to reduce the burden of the damper 3 on the buffer frame 2. When a vehicle collides, the buffer frame 2 will move along the supporting slide rod 19, and the movement is stable through the cooperation of the supporting slide rod 19 and the sliding opening 20. With the movement of the supporting slide rod 19, the pressing rod 18 will be in contact with the guardrail frame 1 to form a limiting structure, preventing the buffer frame 2 from moving continuously and reducing the damage to the damper 3.
[0042] Please refer to Figures 3-5 As a further embodiment of the supporting slide rod, a secondary spring 21 is arranged on the supporting slide rod 19, the secondary spring 21 is sleeved on the supporting slide rod 19 and cooperates with the buffer frame 2 and the guardrail frame 1, and a buffer ring 22 is arranged on the pressing rod 18.
[0043] Specifically, the secondary spring 21 further provides buffering effect when the supporting slide rod 19 moves to absorb the impact of the collision, and the pressing rod 18 is in contact with the guardrail frame 1 through the buffer ring 22 to further provide buffering effect and reduce damage caused by impact.
[0044] Please refer to Figures 1-2 As a further embodiment of the buffer frame, a connecting slot 23 is formed in the side end of the buffer frame 2, a connecting strip 24 is arranged in the connecting slot 23, and a fixing bolt 25 is arranged at both ends of the connecting strip 24. The fixing bolt 25 is in detachable cooperation with the connecting strip 24, and one end is detachably connected with the connecting slot 23 through the fixing bolt 25.
[0045] Specifically, when installing the guardrail device, the connecting strip 24 is installed in the connecting slot 23 of the adjacent buffer frame through the cooperation of the connecting strip 24 and the connecting slot 23, and is fixed by the fixing bolt 25, so that the adjacent buffer frames are integrated. When an impact occurs, the impact is absorbed by the replaced buffer structure to reduce the damage caused by the impact.
[0046] Please refer to Figure 4 As a further embodiment of the guardrail frame, a cross reinforcing frame 26 is arranged in the guardrail frame 1.
[0047] Specifically, the structure strength of the guardrail frame 1 is improved by the cross reinforcement frame 26, so that the guardrail frame 1 has stronger support capacity and is less likely to be damaged.
[0048] In summary, the overall device has the following advantages when in use (or running):
[0049] The basic structure of the guardrail is formed by the cooperation of multiple guardrail frames 1, which protects the two ends of the bridge. The buffer frame 2 is arranged on the guardrail frame 1. When a vehicle hits the guardrail, the buffer frame is in contact with the vehicle through the buffer barrel 6 under the support of the guardrail frame 1, and receives the impact of the vehicle. Under the transmission of the support rod 5, the rotating rod 16 is supported by the extension rod 15, and the buffer barrel 6 is supported by the buffer sleeve 17 and the vehicle outside, so as to avoid the direct impact of the vehicle on the buffer frame 2. The buffer frame 2 receives the impact in turn through the support rod 5 and the buffer frame, and moves in the direction of the guardrail frame 1, so that the damper 3 is retracted to provide space for the movement of the buffer frame, and the buffer spring 4 supports the buffer frame 2 to absorb the impact force received by the buffer frame 2, thereby providing a buffer effect to absorb the impact generated by the vehicle impact. In addition, the buffer sleeve 17 also absorbs part of the impact, and through the connection of the abutting rod 18, the support slide rod 19 cooperates with the sliding port 20 to provide support effect through the support slide rod 19, thereby reducing the burden of the buffer frame 2 on the damper 3. When the buffer frame 2 is hit, it will move along the support slide rod 19, and through the cooperation of the support slide rod 19 and the sliding port 20, the movement is stable. In addition, with the movement of the support slide rod 19, the secondary spring 21 further provides a buffer effect to absorb the impact when the vehicle hits. When the abutting rod 18 is in contact with the guardrail frame 1 through the buffer ring 22, a limiting structure is formed to further absorb the impact and prevent the buffer frame 2 from moving continuously, thereby reducing the damage to the damper 3. In addition, the buffer barrel 6 can rotate along the support rod 5 after being in contact with the vehicle, thereby guiding the direction of the vehicle and making the vehicle gradually deviate from the normal driving direction. The cooperation of the two reduces the impact damage of the guardrail and prevents the vehicle from breaking through the guardrail and out of the bridge.
[0050] When the equipment is damaged by impact, the guardrail can be replaced. Remove the bolts on the fixing plate 9, remove the fixing plate 9 to expose the mounting groove 7, remove the insert plate 8 from the mounting groove 7, so that the insert plate 8 and the support rod 5 are separated from the buffer frame 2. Remove the bolts at the connection between the buffer frame 2 and the connecting plate 10 to remove the buffer frame 2. Alternatively, remove the bolts in the middle part of the connecting plate 10 to separate the connecting plate 10 from the connecting block 11. The buffer frame 2 can also be removed. Repeat the above steps in reverse to assemble the guardrail equipment for replacing the guardrail structure. The equipment is divided into three main parts by the combined structure: guardrail frame 1, buffer frame 2 and support rod 5. Depending on the specific damage to the equipment when it is impacted, only the damaged specific structure needs to be replaced, and the entire equipment does not need to be replaced.
[0051] In addition, during the assembly of the guardrail equipment, the connecting strip 24 is inserted into the connecting groove 23 of the adjacent buffer frame through the cooperation of the connecting strip 24 and the connecting groove 23, and is fixed by the fixing bolt 25, thereby forming the adjacent buffer frames into a whole. When subjected to impact, the replacement buffer structure absorbs the impact and reduces the damage of the impact. When the guardrail equipment is used to protect the bridge, the cross reinforcement frame 26 will further improve the structural strength of the guardrail frame 1, making the guardrail frame 1 have a stronger support capacity and reducing the damage to the guardrail frame 1. With the support of the rotating shaft 13, the contact roller 14 is set on the upper end of the buffer frame 2. Through the rotation setting, the outer end of the contact roller 14 fits more closely with the rotating groove 12, reducing the gap between the contact roller 14 and the buffer frame. If someone wants to climb the guardrail equipment, they need to rely on the uppermost end of the buffer frame 2 as a support point. When the climber comes into contact with the contact roller 14, the contact roller 14 will rotate along the rotating shaft 13 under the force, thereby causing the climber's hand to leave the contact roller 14 and lose the point of leverage, thus avoiding the dangerous behavior of climbing.
[0052] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
