Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a high-strength, corrosion-resistant and anti-collision guardrail. Background Art

[0002] Crash barriers are important safety features installed along the edges of bridges. Typically made of high-strength steel, concrete, or composite materials, they are durable and impact-resistant. They are designed to prevent vehicles from accidentally running off the bridge, protecting both the vehicle and its passengers.

[0003] Existing anti-collision guardrails are generally installed by welding or fixed connections. However, once part of the guardrail is damaged due to factors such as vehicle collision or long-term corrosion, it is difficult to disassemble the damaged part, so it is difficult to replace it in time. This will have an adverse effect on the overall structural stability of the guardrail, thereby shortening the service life of the guardrail and ultimately affecting the normal use of the anti-collision guardrail.

[0004] Therefore, there is an urgent need to improve high-strength corrosion-resistant anti-collision guardrails to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a high-strength, corrosion-resistant, and anti-collision guardrail. By moving the four sliders, the spring is compressed, and the block at the bottom end of the guardrail is inserted into the position between the two clamping columns. When the block is in place, the spring rebounds to make the clamping column clamp the block, thereby enabling the guardrail and the lower crossbeam to be quickly assembled and disassembled, facilitating the later maintenance and replacement of the guardrail, and effectively ensuring the stability of the guardrail during use. Even under the action of external forces such as vehicle collisions, it can ensure that the guardrail will not easily loosen or fall off, thereby effectively exerting the protective role of the anti-collision guardrail.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0007] A high-strength, corrosion-resistant, and anti-collision guardrail comprises two upright posts, an upper crossbeam is provided between the two upright posts, a lower crossbeam is provided below the upper crossbeam, a guardrail is provided between the upper crossbeam and the lower crossbeam, and the lower crossbeam is provided with a plurality of evenly distributed mounting grooves, wherein mounting components are provided inside the mounting grooves;

[0008] The cam is secured to the interior of the frame with a secure connection to the guide rails, and the cam has a latching mechanism which engages with the latching mechanism and engages with the guide rails to engage with the latching mechanism.

[0009] Preferably, a first fixing bolt is provided below the lower cross beam, and one end of the first fixing bolt passes through the lower cross beam and the mounting groove and is threadedly connected to the bottom end of the mounting frame.

[0010] Preferably, a fixing plate is fixedly mounted on the upper end of the guardrail, and a second fixing bolt is provided on the fixing plate.

[0011] Preferably, the upper cross beam is provided with a plurality of evenly distributed slots, the slots corresponding to the fixing plate, and one end of the second fixing bolt passes through the fixing plate and is threadedly connected to the inner bottom surface of the slot.

[0012] Preferably, the outer side of the guardrail is coated with anti-corrosion paint.

[0013] Preferably, a reinforcing rib is fixedly installed inside the guardrail, a buffer is provided on the outside of the reinforcing rib, and the buffer is arranged inside the guardrail.

[0014] Preferably, a plurality of evenly distributed fastening bolts are fixedly mounted on the bottom ends of the two columns.

[0015] The utility model has at least the following beneficial effects:

[0016] 1. The utility model moves four sliders, the spring is compressed, and the block at the bottom end of the guardrail is inserted into the position between the two clamping columns. When the block is in place, the spring rebounds to make the clamping column clamp the block, thereby realizing the rapid assembly and disassembly of the guardrail and the lower crossbeam, facilitating the later maintenance and replacement of the guardrail, and effectively ensuring the stability of the guardrail during use. Even under the action of external forces such as vehicle collisions, it can ensure that the guardrail will not loosen or fall off easily, thereby effectively playing the protective role of the anti-collision guardrail.

[0017] 2. The anti-corrosion paint applied on the outside of the guardrail of the utility model protects the guardrail from erosion by the external environment and prolongs the service life of the guardrail. The reinforcing ribs inside the guardrail enhance the overall strength of the guardrail, making it less likely to deform and damage when subjected to external forces such as vehicle collisions. A buffer is also provided on the outside of the reinforcing rib, which is polyurethane foam. When a vehicle hits the guardrail, the polyurethane foam can absorb and disperse the impact force, reduce the degree of damage to the vehicle and the guardrail caused by the collision, and thus improve the reliability and safety of the anti-collision guardrail.

DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figure 1-Figure 5As shown, the high-strength, corrosion-resistant, and anti-collision guardrail provided in this embodiment includes two columns 1, an upper crossbeam 2 is provided between the two columns 1, a lower crossbeam 3 is provided below the upper crossbeam 2, a guardrail 4 is provided between the upper crossbeam 2 and the lower crossbeam 3, and a plurality of evenly distributed mounting grooves 5 are opened on the lower crossbeam 3, and a mounting assembly 6 is provided inside the mounting groove 5;

[0027] The mounting assembly 6 includes a mounting frame 601, and a plurality of evenly distributed sliding holes 602 are provided on the mounting frame 601 and the mounting slot 5, and a guide rod 603 is fixedly installed inside the mounting frame 601, and a symmetrically distributed sliding ring 604 is slidably connected to the guide rod 603, and a clamping column 605 is fixedly installed on the upper end of the sliding ring 604, and a slider 606 is fixedly installed on both ends of the clamping column 605, and the end of the slider 606 away from the clamping column 605 passes through the sliding hole 602 and extends to one side of the sliding hole 602, and the slider 606 is slidably connected to the sliding hole 602, and a slot block 607 is fixedly installed on one side of the clamping column 605, and a spring 608 is provided on one side of the slot block 607, one end of the spring 608 is fixedly connected to the inner bottom surface of the slot block 607, and the other end of the spring 608 is fixedly connected to the inner side wall of the mounting frame 601, and a clamping block 609 is provided on the adjacent side of the two clamping columns 605, and the clamping block 609 is connected to the two When the locking block 609 is fully inserted into the corresponding position between the two locking columns 605, the rebound force of the spring 608 pushes the locking column 605 to reset, so that the locking column 605 is stuck to the locking block 609, thereby realizing the rapid assembly and disassembly of the guardrail 4 and the lower crossbeam 3, facilitating the later maintenance and replacement of the guardrail 4, and effectively ensuring the stability of the guardrail 4 during use. Even under the action of external forces such as vehicle collisions, it can ensure that the guardrail 4 will not easily loosen or fall off, thereby effectively playing the protective role of the anti-collision guardrail.

[0028] Further, such as Figure 1-Figure 5 As shown, a first fixing bolt 7 is provided below the lower cross beam 3, one end of the first fixing bolt 7 passes through the lower cross beam 3 and the mounting groove 5 and is threadedly connected to the bottom end of the mounting frame 601, and the mounting frame 601 is fixed inside the mounting groove 5 by the first fixing bolt 7. When the guardrail 4 is subjected to external forces such as vehicle collision, the mounting frame 601 may be subjected to the impact force transmitted from the clamping column 605. The first fixing bolt 7 can effectively prevent the mounting frame 601 from loosening or displacement, and when the mounting frame 601 is damaged, the mounting frame 601 can be disassembled and repaired in time, thereby improving the maintenance convenience of the anti-collision guardrail.

[0029] Further, such as Figure 1-Figure 5 As shown, a fixing plate 8 is fixedly installed on the upper end of the guardrail 4, and a second fixing bolt 9 is provided on the fixing plate 8. A number of evenly distributed slots 10 are opened on the upper crossbeam 2, and the slots 10 correspond to the fixing plate 8, and one end of the second fixing bolt 9 passes through the fixing plate 8 and is threadedly connected with the inner bottom surface of the slot 10. During installation, the guardrail 4 is passed through the slot 10, and the block 609 at the bottom end of the guardrail 4 is abutted against the two clamping columns 605 on the mounting assembly 6. The fixing plate 8 at the upper end of the guardrail 4 is abutted against the slot 10, and then the fixing plate 8 is fixed to the slot 10 by the second fixing bolt 9. When subjected to external forces such as vehicle collisions, the impact force on the upper end of the guardrail 4 can be effectively transmitted to the upper crossbeam 2 through the fixing plate 8 and the second fixing bolt 9, thereby dispersing the force and avoiding loosening or displacement of the upper end of the guardrail 4, thereby ensuring the stability and reliability of the overall structure of the anti-collision guardrail, thereby improving the impact resistance of the anti-collision guardrail.

[0030] Further, such as Figure 1-Figure 5 As shown, the outer side of the guardrail 4 is coated with an anti-corrosion paint 11, and a reinforcing rib 12 is fixedly installed inside the guardrail 4. A buffer 13 is provided on the outer side of the reinforcing rib 12, and the buffer 13 is arranged inside the guardrail 4. The anti-corrosion paint 11 coated on the outer side of the guardrail 4 plays a role in protecting the guardrail 4 from erosion by the external environment and extending the service life of the guardrail 4. The reinforcing rib 12 inside the guardrail 4 enhances the overall strength of the guardrail 4, making it less likely to be deformed and damaged when subjected to external forces such as vehicle collisions, and a buffer 13 is also provided on the outer side of the reinforcing rib 12. The buffer 13 is polyurethane foam. When a vehicle hits the guardrail 4, the polyurethane foam can absorb and disperse the impact force, reduce the degree of damage to the vehicle and the guardrail 4 caused by the collision, thereby improving the reliability and safety of the anti-collision guardrail.

[0031] Further, such as Figure 1-Figure 5 As shown, the bottom ends of the two columns 1 are fixed with a number of evenly distributed fastening bolts 14, which can fix the columns 1 to the ground through the fastening bolts 14, ensuring that the columns 1 will not tilt or shift when subjected to external forces such as vehicle collisions. When a vehicle hits the guardrail, the column 1 can effectively transmit the impact force to the ground, reducing damage to other parts.

[0032] like Figure 1-Figure 5 As shown, the principle of the high-strength corrosion-resistant anti-collision guardrail provided in this embodiment is as follows:

[0033] When installing the guardrail, pass the guardrail 4 through the slot 10, move the four sliders 606, drive the slider 606 to move in the slide hole 602, compress the spring 608 on one side of the slot block 607, and make the slip ring 604 on the clamping column 605 slide along the guide rod 603, and align the clamping block 609 at the bottom end of the guardrail 4 with the position between the two clamping columns 605 and insert it. When the clamping block 609 completely enters the corresponding position between the two clamping columns 605, the rebound force of the spring 608 pushes the clamping column 605 to reset, so that the clamping column 605 clamps the clamping block 609, and the fixing plate 8 at the upper end of the guardrail 4 is against the slot 10, and then the fixing plate is fixed by the second fixing bolt 9. 8 is fixed on the slot 10, so that the guardrail 4 can be quickly assembled. The anti-corrosion coating 11 coated on the outside of the guardrail 4 plays a role in protecting the guardrail 4 from erosion by the external environment and extending the service life of the guardrail 4. The reinforcing ribs 12 inside the guardrail 4 enhance the overall strength of the guardrail 4, making it less likely to be deformed and damaged when subjected to external forces such as vehicle collisions, and a buffer member 13 is also provided on the outside of the reinforcing rib 12. The buffer member 13 is polyurethane foam. When a vehicle hits the guardrail 4, the polyurethane foam can absorb and disperse the impact force, reduce the degree of damage to the vehicle and the guardrail 4 caused by the collision, and thus can effectively play the protective role of the anti-collision guardrail.
