Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision guardrails, in particular to an anti-collision guardrail for bridges with a fast disassembly and assembly function. Background Technique

[0002] The bridge anti-collision guardrail is an important facility for protecting bridges, passing vehicles and pedestrians. Its main function is to prevent vehicles from rushing out of the bridge deck when out of control, falling into the water or hitting the bridge body, causing harm to the bridge itself and the passengers in the vehicle.

[0003] As disclosed in a Chinese patent: A bridge safety guardrail, publication number: CN221480550U. By setting an elastic telescopic mechanism and an anti-collision buffer beam on the traditional bridge guardrail column, multiple buffering can be effectively realized, thereby absorbing the kinetic energy generated by vehicle collision; by arranging multiple layers of buffer fillers in the inner cavity of the anti-collision buffer beam, the first buffer for the collided vehicle can be realized; by setting the surface of the anti-collision buffer beam facing the inner side of the bridge as an arc surface, the stiffness of the anti-collision buffer beam can be increased, and at the same time, secondary injury to the passengers in the vehicle caused by sharp corners can be avoided.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following technical problems: The above device connects the anti-collision beam through a bolt assembly. To ensure the firmness of the installation connection, the bolts are usually tightened tightly. When the anti-collision beam needs to be disassembled and repaired regularly or replaced after an accident, the anti-collision beam connected by bolts takes more time and effort to disassemble, increasing the maintenance cost and time. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides an anti-collision guardrail for bridges with a fast disassembly and assembly function, and solves the technical problem that the above device connects the anti-collision beam through a bolt assembly. To ensure the firmness of the installation connection, the bolts are usually tightened tightly. When the anti-collision beam needs to be disassembled and repaired regularly or replaced after an accident, the anti-collision beam connected by bolts takes more time and effort to disassemble, increasing the maintenance cost and time.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model is realized through the following technical solutions:

[0009] An anti-collision guardrail for bridges with a quick disassembly and assembly function, including columns. A mounting seat is slidably connected inside the columns. An anti-collision buffer beam is sleeved on the outer surface of the mounting seat. A threaded rod is threadedly connected inside the mounting seat. A round rod is fixedly connected inside the threaded rod. A retaining ring is sleeved inside the anti-collision buffer beam. The round rod is clamped inside the retaining ring. A through groove is opened inside the retaining ring. The round rod and the through groove are adapted to each other. A positioning mechanism is fixedly connected to the outer surface of the mounting seat. The positioning mechanism includes a positioning plate, and the positioning plate is fixedly connected to the outer surface of the mounting seat.

[0010] Preferably: A connecting plate is slidably connected to one side of the inside of the column close to the anti-collision buffer beam.

[0011] Preferably: A buffer spring is sleeved inside the column.

[0012] Preferably: A connecting block is fixedly connected to the outer surface of the column.

[0013] Preferably: A chute is opened inside the column and the connecting block. A slider is fixedly connected to the outer surface of the connecting plate.

[0014] Preferably: A pneumatic spring is fixedly connected to the outer surface of the connecting block.

[0015] (III) Beneficial effects

[0016] First, when it is necessary to remove the mounting seat for inspection or replace the anti-collision buffer beam after a collision, turn the threaded rod to make the round rod slide towards one end of the retaining ring. After the round rod slides out of the retaining ring, manually turn the through groove by ninety degrees. At this time, the through groove and the round rod are in the same vertical direction. Then pull the retaining ring outwards to remove it. The anti-collision buffer beam loses the limit clamping of the retaining ring, and then the anti-collision buffer beam can be pulled out horizontally. The operation is simple and convenient, without the need to carry additional tools for disassembly, which is beneficial to improving the speed and convenience of disassembly and assembly.

[0017] Second, when a collision accident occurs, the anti-collision buffer beam squeezes the mounting seat to slide, and is buffered by the buffer spring during the sliding process. When the anti-collision buffer beam slides, it drives the connecting plate to slide synchronously towards one end of the connecting block by squeezing the retaining ring and the threaded rod. During the sliding process of the connecting plate, the pneumatic spring further absorbs the impact energy, improving the multi-stage nature of the buffer. And the pneumatic spring can provide a gradually increasing damping force instead of a sudden reaction force, thereby reducing the rebound situation after the collision and reducing the risk of injury.

Specific embodiments

[0024] In the embodiment of the present application, by providing an anti-collision guardrail for bridges with a quick disassembly and assembly function, the above-mentioned device effectively solves the problem that the anti-collision beam is connected by a bolt assembly. To ensure the firmness of the installation connection, the bolts are usually tightened tightly. When the anti-collision beam needs to be disassembled and repaired regularly or replaced after an accident, the anti-collision beam connected by bolts takes more time and effort to disassemble, increasing the maintenance cost and time. When the mounting seat needs to be disassembled and inspected or the anti-collision buffer beam needs to be replaced after a collision, the threaded rod is rotated, so that the round rod slides towards the retaining ring end. After the round rod slides out from the retaining ring, the through slot is manually rotated by 90 degrees. At this time, the through slot and the round rod are in the same vertical direction. Then, the retaining ring is pulled outwards. The anti-collision buffer beam loses the limit clamping of the retaining ring, and then the anti-collision buffer beam can be pulled out horizontally. The operation is simple and convenient, and there is no need to carry additional tools for disassembly, which is beneficial to improving the speed and convenience of disassembly and assembly.

[0025] Embodiment

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problem that when the above-mentioned device connects the anti-collision beam through the bolt assembly, in order to ensure the firmness of the installation connection, the bolts are usually screwed tightly. When the anti-collision beam needs to be disassembled and repaired regularly or replaced after an accident, the anti-collision beam connected by bolts takes more time and effort to disassemble during disassembly, increasing the maintenance cost and time. The general idea is as follows: An anti-collision guardrail for a bridge with a quick disassembly and assembly function includes a column 11. An installation seat 12 is slidably connected inside the column 11. An anti-collision buffer beam 13 is sleeved on the outer surface of the installation seat 12. A threaded rod 14 is threadedly connected inside the installation seat 12. A round rod 15 is fixedly connected inside the threaded rod 14. A retaining ring 16 is sleeved inside the anti-collision buffer beam 13. The round rod 15 is clamped inside the retaining ring 16. A through groove 17 is formed inside the retaining ring 16. The round rod 15 and the through groove 17 are adapted to each other. When it is necessary to remove the installation seat 12 for inspection or replace the anti-collision buffer beam 13 after a collision, the threaded rod 14 is screwed, so that the round rod 15 slides towards one end of the retaining ring 16. After the round rod 15 slides out of the retaining ring 16, the through groove 17 is manually screwed 90 degrees. At this time, the through groove 17 and the round rod 15 are in the same vertical direction. Then, the retaining ring 16 is pulled outwards. The anti-collision buffer beam 13 loses the limiting clamping of the retaining ring 16, and the anti-collision buffer beam 13 can be pulled out horizontally. The operation is simple and convenient, and there is no need to carry extra tools for disassembly, which is beneficial to improving the speed and convenience of disassembly and assembly.

[0027] A positioning mechanism is fixedly connected to the outer surface of the installation seat 12. The positioning mechanism includes a positioning plate 18. The positioning plate 18 is fixedly connected to the outer surface of the installation seat 12. The anti-collision buffer beam 13 is sleeved on the inner surface of the positioning plate 18. A connecting plate 19 is slidably connected to one side of the column 11 close to the anti-collision buffer beam 13. The threaded rod 14 is rotatably connected inside the connecting plate 19. A buffer spring 21 is sleeved inside the column 11. The buffer spring 21 is sleeved on the outer surface of the installation seat 12. A connecting block 22 is fixedly connected to the outer surface of the column 11. When the two columns 11 are installed on the bridge, the connecting plate 19 installed between the two columns 11 is used to connect and support them. By installing the connecting plate 19 on the positioning plate 18, when a collision occurs, the collision object contacts the anti-collision buffer beam 13, and the installation seat 12 is squeezed to slide towards one end of the connecting block 22 during the collision process. During the sliding process, the buffer spring 21 absorbs energy, reducing the probability of secondary injury to personnel.

[0028] The vertical column 11 and the connecting block 22 are internally provided with sliding grooves 23. The outer surface of the connecting plate 19 is fixedly connected with a sliding block 24, and the sliding block 24 is slidably connected inside the sliding groove 23. The outer surface of the connecting block 22 is fixedly connected with a pneumatic spring 25, and the pneumatic spring 25 is fixedly connected to the outer surface of the connecting plate 19. When a collision accident occurs, the anti-collision buffer beam 13 squeezes the mounting seat 12 to slide, and is buffered by the buffer spring 21 during the sliding process. When the anti-collision buffer beam 13 slides, it drives the connecting plate 19 to slide synchronously towards one end of the connecting block 22 through the retaining ring 16 and the threaded rod 14 (the connecting plate 19 slides in the sliding groove 23 through the sliding block 24 and is integrally squeezed and slid during a collision accident to ensure the integrity of the whole and avoid the threaded rod 14 being squeezed and deformed during a collision due to the fixed installation of the connecting plate 19). During the sliding process of the connecting plate 19, the pneumatic spring 25 further absorbs the impact energy (the pneumatic spring 25 generates an elastic force through the gas enclosed inside. When an external force compresses the pneumatic spring 25, the internal gas is compressed to generate gas pressure, thereby providing a reverse thrust or supporting force. When the external force is released, the gas expands and the pneumatic spring 25 returns to its original state to achieve the functions of buffering and rebounding, which belongs to the prior art), improving the multi-stage nature of buffering. Moreover, the pneumatic spring 25 can provide a gradually increasing damping force instead of a sudden reaction force, thereby reducing the rebound situation after a collision and reducing the risk of injury.

[0029] Aiming at the problems existing in the prior art, the utility model provides an anti-collision guardrail for bridges with a quick disassembly and assembly function. When it is necessary to remove and inspect the mounting seat 12 or replace the anti-collision buffer beam 13 after a collision, the threaded rod 14 is rotated, so that the round rod 15 slides towards one end of the retaining ring 16. After the round rod 15 slides out of the retaining ring 16, the through groove 17 is manually rotated by 90 degrees. At this time, the through groove 17 and the round rod 15 are in the same vertical direction. Then, the retaining ring 16 is pulled outwards to be removed. The anti-collision buffer beam 13 loses the limiting clamping of the retaining ring 16, and the anti-collision buffer beam 13 can be horizontally pulled out. The operation is simple and convenient, without the need to carry external tools for disassembly, which is beneficial to improving the speed and convenience of disassembly and assembly.

[0030] Working principle:

[0031] In the first step, two vertical columns 11 are installed on the bridge and are connected and supported by the connecting plate 19 installed between the two vertical columns 11. By installing the connecting plate 19 on the positioning plate 18, when a collision occurs, the collision object contacts the anti-collision buffer beam 13, and during the collision process, the mounting seat 12 is squeezed to slide towards one end of the connecting block 22. During the sliding process, the buffer spring 21 absorbs the energy, reducing the probability of secondary injury to personnel.

[0032] Second step, when it is necessary to remove and inspect the mounting seat 12 or replace the anti-collision buffer beam 13 after a collision, turn the threaded rod 14 to make the round rod 15 slide towards the retaining ring 16. After the round rod 15 slides out of the retaining ring 16, manually turn the through groove 17 by 90 degrees. At this time, the through groove 17 and the round rod 15 are in the same vertical direction. Then pull the retaining ring 16 outwards. The anti-collision buffer beam 13 loses the limit clamping of the retaining ring 16, and then the anti-collision buffer beam 13 can be pulled out horizontally. The operation is simple and convenient, without the need to carry additional tools for disassembly, which is beneficial to improving the speed and convenience of disassembly and assembly. When a collision accident occurs, the anti-collision buffer beam 13 squeezes the mounting seat 12 to slide, and is buffered by the buffer spring 21 during the sliding process. When the anti-collision buffer beam 13 slides, it drives the connecting plate 19 to slide synchronously towards the connecting block 22 by squeezing the retaining ring 16 and the threaded rod 14 (the connecting plate 19 slides in the chute 23 through the slider 24 and is integrally squeezed and slid during a collision accident to ensure the integrity of the whole, and avoid the threaded rod 14 being squeezed and deformed during a collision due to the fixed installation of the connecting plate 19). During the sliding process of the connecting plate 19, the impact energy is further absorbed by the pneumatic spring 25 (the pneumatic spring 25 generates elastic force through the gas sealed inside. When an external force compresses the pneumatic spring 25, the internal gas is compressed to generate gas pressure, thereby providing a reverse thrust or supporting force. When the external force is released, the gas expands, causing the pneumatic spring 25 to return to its original state, realizing the functions of buffering and rebounding, which belongs to the prior art). This improves the multi-stage nature of buffering, and the pneumatic spring 25 can provide a gradually increasing damping force instead of a sudden reaction force, thereby reducing the rebound situation after a collision and reducing the risk of injury.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
