Description

Technical Field

[0001] This utility model relates to the field of traffic safety engineering, and in particular to a high-performance anti-collision guardrail for municipal engineering. Background Technology

[0002] Crash barriers for municipal engineering are safety protection facilities used in urban roads, bridges, highways and other traffic infrastructure. Their main function is to reduce vehicle crossing and collisions when vehicles lose control or are involved in traffic accidents, thereby protecting the safety of drivers and passengers and reducing the losses caused by accidents.

[0003] In existing municipal engineering projects, most commonly used crash barriers rely on the strength and rigidity of the barrier materials themselves to absorb and resist the energy generated during vehicle collisions. However, this traditional barrier design has some drawbacks. For example, these materials may not be able to effectively absorb enough energy under extreme collision conditions, thus failing to adequately protect the safety of drivers and passengers. In addition, these materials may not be corrosion-resistant, leading to reduced durability of the barriers in harsh environments. Furthermore, existing barriers are often continuous structures, meaning that when a section is damaged, the entire damaged section needs to be replaced due to the interconnected design. This repair method is not only time-consuming and labor-intensive but also increases repair costs and traffic disruption time. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies that rely solely on materials for impact protection and require the entire railing to be replaced when a section is damaged. The proposed high-performance impact protection railing for municipal engineering uses a delay component to diffuse the impact force to both sides of the device when the railing is hit, so that the impact force is mitigated and then transferred to the ground, enabling the railing to withstand greater impact force than existing railings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance anti-collision guardrail for municipal engineering, comprising a base, a top box fixedly connected to the top of the base, a circular tube fixedly connected to the inner wall of the top box, a delay component provided on the inner wall of the circular tube, the circular tube being connected to a connecting rod through the delay component, a connecting block rotatably connected to the outer wall of the connecting rod, a cover fixedly connected to the outer wall of the connecting block, the cover being used to cover the outer wall of the top box, a connecting box fixedly connected to the right end of the base, a locking component provided on the inner wall of the connecting box, and the connecting box being connected to a connecting box through the locking component.

[0006] Furthermore, the delay component includes a first compression spring fixedly connected to the bottom end of the inner wall of the circular tube, a first pressure ring fixedly connected to the top end of the first compression spring, the outer wall of the first pressure ring slidably connected to the inner wall of the circular tube, a bottom rod fixedly connected to the top end of the first pressure ring, and a connecting rod fixedly connected to the top end of the bottom rod.

[0007] Furthermore, a rotator is rotatably connected to the outer wall of the connecting rod, and a pulley is rotatably connected to the bottom end of the rotator. The bottom end of the pulley slides on the top of the inner wall of the top box.

[0008] Furthermore, a sliding rod is fixedly connected to the four corners of the bottom end of the cover, and a bottom tube is slidably connected to the inner wall of the sliding rod. The bottom end of the bottom tube is fixedly connected to the top of the inner wall of the top box.

[0009] Furthermore, the locking assembly includes a second compression spring slidably connected to the inner wall of the connecting box, an insert rod fixedly connected to the inner wall of the second compression spring, and a second pressure ring fixedly connected to the outer wall of the insert rod, the second pressure ring being used to compress the second compression spring.

[0010] Furthermore, a connector is fixedly connected to the outer wall of the connecting box, and the front end of the insertion rod passes through the connector.

[0011] Furthermore, a connecting box is fixedly connected to the left end of the base, and a locking block is fixedly connected to the outer wall of the connecting box. A slot is provided on the inner wall of the locking block for inserting a plug rod. The locking blocks have slots on both sides of the inner wall for engaging connectors.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, when a vehicle impacts the cover, the cover moves towards the top box, causing it to move downward against the connecting block. This causes some of the force to slide to both sides through the pulleys on the rotator, reducing the impact force. Then, some of the force impacts the first compression spring and dissipates, allowing the guardrail to withstand a greater impact force than existing guardrails.

[0014] In this invention, a connecting box on a guardrail is aligned with a connecting box, and then moved downwards so that the connector is inserted into the slot on the card block, causing the insertion rod to slide backwards. Then, when the connector has slid to the bottom, the insertion rod is aligned with the slot on the card block, and the second compression spring rebounds to insert the insertion rod into the slot. This allows for quick replacement of damaged guardrail sections, greatly improving the practicality of the device. Attached Figure Description

[0021] 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.

[0022] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a high-performance anti-collision guardrail for municipal engineering, comprising a base 1, a top box 2 fixedly connected to the top of the base 1, a circular tube 16 fixedly connected to the inner wall of the top box 2, a delay component 9 provided on the inner wall of the circular tube 16, and the circular tube 16 connected to a connecting rod 13 through the delay component 9. The delay component 9 includes a first compression spring 19 fixedly connected to the bottom end of the inner wall of the circular tube 16, a first pressure ring 18 fixedly connected to the top of the first compression spring 19, the outer wall of the first pressure ring 18 slidably connected to the inner wall of the circular tube 16, and a first pressure ring 18 fixedly connected to the top of the first pressure ring 18. A base rod 17 is fixedly connected to a connecting rod 13 at its top end. A rotatable actuator 14 is rotatably connected to the outer wall of the connecting rod 13. A pulley 15 is rotatably connected to the bottom end of the rotatable actuator 14. The bottom end of the pulley 15 slides on the top end of the inner wall of the top box 2. A connecting block 12 is rotatably connected to the outer wall of the connecting rod 13. A cover shell 8 is fixedly connected to the outer wall of the connecting block 12. The cover shell 8 is used to cover the outer wall of the top box 2. A sliding rod 10 is fixedly connected to the four corners of the bottom end of the cover shell 8. A bottom tube 11 is slidably connected to the inner wall of the sliding rod 10. The bottom end of the bottom tube 11 is fixedly connected to the top end of the inner wall of the top box 2.

[0023] Specifically, the installation team fixed the base 1 at the location requiring protection, ensuring its stability to withstand the impact from the guardrail. When the guardrail was impacted by a vehicle, the vehicle impacted the cover 8, causing it to move forward under the impact force. This pressure caused the cover 8 to apply pressure to the connecting block 12, which in turn moved the connecting rod 13 forward. The forward movement of the connecting rod 13 then pushed the bottom rod 17, causing it to slide with the first pressure ring 18 inside the round tube 16. The movement of the first pressure ring 18 then compressed the first compression spring 19, causing it to contract and thus mitigating some of the impact force. Simultaneously, most of the impact force was transmitted through the connecting rod 13 to the rotator 14 on its outer wall. After being compressed, the rotator 14 moved forward, causing the pulley 15 at its bottom end to move to both sides of the device, allowing the impact force to disperse to the upper and lower sides of the top box 2. Finally, this dispersed impact force was transmitted to the ground through the base 1 at the bottom of the top box 2, effectively dispersing and absorbing the collision energy and protecting the safety of the vehicle and its occupants.

[0024] Reference Figure 1 and Figure 4A connecting box 6 is fixedly connected to the right end of the base 1. A locking component 20 is provided on the inner wall of the connecting box 6. The connecting box 6 is connected to the connecting box 3 through the locking component 20. The locking component 20 includes a second compression spring 21 that is slidably connected to the inner wall of the connecting box 6. A plug rod 7 is fixedly connected to the inner wall of the second compression spring 21. A second pressure ring 22 is fixedly connected to the outer wall of the plug rod 7. The second pressure ring 22 is used to compress the second compression spring 21. A connector 23 is fixedly connected to the outer wall of the connecting box 6. The front end of the plug rod 7 passes through the connector 23. A connecting box 3 is fixedly connected to the left end of the base 1. A locking block 4 is fixedly connected to the outer wall of the connecting box 3. A slot 5 is opened on the inner wall of the locking block 4. The slot 5 is used to insert the plug rod 7. The locking grooves 24 are opened on both sides of the inner wall of the locking block 4. The locking grooves 24 are used to engage the connector 23.

[0025] Specifically, the construction team selects a suitable location for guardrail installation based on the design drawings and actual site conditions. They then retrieve prefabricated guardrail units from storage for assembly. The installers precisely align the connecting box 6 on the right side of one guardrail with the connecting box 3 on the left side of the adjacent guardrail. After ensuring the correct alignment of connecting box 6 and connecting box 3, they align the two sides of the connector 23 with the slots 24 on the fixed blocks 4 of the connecting box 6. The installers then press down on the connecting box 6 while simultaneously pulling the insert rod 7 backward, causing the second pressure ring 22 on its outer wall to move backward. As the second pressure ring 22 moves, it applies pressure to the second compression spring 21, compressing it. After the connector 23 smoothly passes through the slot 24 and engages with the block 4, the installers release their grip. This causes the second compression spring 21 to rebound, firmly inserting the front end of the insert rod 7 into the slot 5. To ensure a stable connection, the installers shake the connecting box 6. Once they confirm that the connecting box 6 is not loose, the installation is considered complete.

[0026] Working principle: First, take out the guardrail to be installed. Then, align the connecting box 6 on the right side of one guardrail with the connecting box 3 on the left side of the other guardrail. Next, ensure that both sides of the connector 23 are aligned with the slots 24 on the fixed blocks 4 on the connecting box 6. Then, press down on the connecting box 6. As the connector 23 slides down, pull the insert rod 7 backward to move the insert rod 7 backward. This causes the insert rod 7 to move backward along with the second pressure ring 22 on its outer wall. The movement of the second pressure ring 22 causes it to compress the second pressure spring 21. The connector 23 is then inserted into the block 4 through the slots 24. Release the pressure ring to allow the second pressure spring 21 to return to its original position. Insert the front end of the insert rod 7 into the slot 5. After inserting the bottom insert rod 7 into the corresponding slot 5, shake the connecting box 6. Once you confirm that the connecting box 6 cannot move, the installation is considered complete.

[0027] Then, by installing the base 1 at the location requiring protection, when the guardrail is impacted, the cover 8 is moved forward by the impact force, causing the cover 8 to press against the connecting block 12, causing the connecting block 12 to move forward with the connecting rod 13, and then the connecting rod 13 moves forward, causing the connecting rod 13 to push against the bottom rod 17 and move forward. Then, through the forward movement of the bottom rod 17, the bottom rod 17, along with the first pressure ring 18, slides inside the round tube 16, causing the first pressure ring 18 to press against the first pressure spring 19, causing the first pressure spring 19 to be compressed and contracted, relieving part of the force with the rebound force of the first pressure spring 19. Then, most of the force is transmitted through the connecting rod 13 to the rotator 14 on its outer wall, causing the rotator 14 to be pressed forward, causing the pulley 15 at the bottom of the rotator 14 to move to both sides of the device, causing the impact force to spread to the upper and lower sides of the top box 2, and then the spread impact force is transmitted to the ground through the base 1 at the bottom of the top box 2.

[0028] 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.
