Description

Technical Field

[0001] The present application relates to the technical field of corrugated beam guardrails, and in particular to a low-consumption, anti-collision corrugated beam guardrail. Background Art

[0002] The corrugated beam guardrail is a guardrail beam with a corrugated cross section, usually made by stamping or bending steel plates. Due to its corrugated cross section, it has good collision resistance and energy absorption. The guardrail with a corrugated beam structure is not easily destroyed, and at the same time it can provide good protection for vehicles and drivers and passengers.

[0003] The purpose of a corrugated beam guardrail mentioned in the existing Chinese public patent (authorization announcement number: CN212223704U) is to place a buffer block and a corrugated steel guardrail plate to slide. When a vehicle hits the corrugated beam guardrail, the buffer block first contacts the vehicle and slides close to the column under the impact force of the vehicle. When the buffer block slides to be flush with the highest point of the curved surface of the corrugated steel guardrail plate, the vehicle will contact the corrugated steel guardrail plate and impact the corrugated steel guardrail plate. When the vehicle directly contacts the corrugated steel guardrail plate, the buffer block first buffers the impact of the vehicle, so that after the vehicle contacts the corrugated steel guardrail plate, the impact force becomes smaller, thereby protecting the corrugated steel guardrail plate.

[0004] When the existing corrugated beam guardrail is impacted, most of them are able to absorb the collision by deforming the corrugated beam, thus protecting the vehicle and the driver and passengers. However, when the impact force is large, the impact force may be transmitted to the column, which may cause the column to tilt and fall, causing the corrugated beam guardrail to lose its support and protection function as a whole, increasing the risk of injury to the vehicle and passengers.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a low-consumption, anti-collision corrugated beam guardrail.

[0034] Reference Figures 1 to 3 A low-consumption, anti-collision corrugated beam guardrail comprises two columns 1, one side of the columns 1 on both sides is fixedly connected with a fixed block 2, one side of the fixed block 2 is provided with a fixed plate 3, both sides of the fixed plate 3 are fixedly connected with connecting blocks 4, and the end of the connecting block 4 away from the fixed plate 3 is provided with a corrugated beam guardrail body 5, the corrugated beam guardrail body 5 and the connecting block 4 are fixed by bolts 6, a buffer mechanism is provided on a side of the fixed plate 3 close to the fixed block 2, and a reinforcement mechanism is provided on a side of the column 1 away from the fixed block 2.

[0035] When protecting the road surface, first move the column 1 to a suitable position, then place the corrugated beam guardrail body 5 on one side of the fixed plate 3, and then threadably connect it to the corrugated beam guardrail body 5 through the connecting block 4, so that the corrugated beam guardrail body 5 is fixed on one side of the connecting block 4. When impacted, the corrugated beam guardrail body 5 deforms to absorb energy, thereby protecting the vehicle and the driver and passengers. By setting the column 1 to a hollow shape, while reducing material consumption, the impact resistance of the column 1 can also be improved. The impact of the corrugated beam guardrail body 5 can be buffered by the buffer mechanism, thereby protecting the corrugated beam guardrail body 5. The column 1 can be reinforced by the reinforcement mechanism to reduce the risk of the column 1 tilting or tipping over when impacted.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The reinforcement mechanism includes a rotating seat 7 fixedly connected to one side of the column 1, a telescopic cylinder 8 is rotatably connected inside the rotating seat 7, a telescopic rod 9 is slidably connected inside the telescopic cylinder 8, the bottom end of the telescopic rod 9 is rotatably connected to a base 10, a plurality of latch teeth 13 are equidistantly fixedly connected to the bottom of the base 10, and a reinforcement piece is arranged inside the base 10.

[0037] A second bolt 11 is slidably disposed inside the telescopic tube 8 , and a plurality of thread grooves 12 are equidistantly provided on one side of the telescopic rod 9 , and the second bolt 11 is threadedly connected to the thread groove 12 .

[0038] In addition, the reinforcement part includes a reinforcement groove opened inside the base 10, and the inner sides of the reinforcement groove are rotatably connected with a rotating shaft 14, the outer surface of the rotating shaft 14 is fixedly connected with a rotating plate 15, and the rotating plate 15 has a sliding hole 16 opened inside, and an insert rod 17 is slidably arranged inside the sliding hole 16, and the bottom end of the insert rod 17 is set to be conical.

[0039] When supporting the column 1, the telescopic cylinder 8 is rotated to a suitable angle, and then the telescopic rod 9 is slid inside the telescopic cylinder 8. The movement of the telescopic rod 9 will drive the base 10 to move downward, so that the base 10 contacts the ground. The base 10, the telescopic rod 9 and the telescopic cylinder 8 are used to support the column 1, thereby improving the stability of the column 1 when it is impacted and reducing the risk of overturning of the column 1. The firmly supported column 1 can better resist external impacts, so that the guardrail can effectively play a protective role and reduce the risk of injury to vehicles and passengers. When dealing with different road conditions, the position of the telescopic rod 9 can be fixed by passing the bolt 2 11 through the telescopic cylinder 8 and threading it with the threaded groove 12 on the telescopic rod 9, thereby improving the flexibility and applicability of fixing the column 1. When the base 10 contacts the road surface, the rotating plate 15 is rotated out, and then the insertion rod 17 is placed in the rotating plate 15, and then the insertion rod 17 is hit so that the insertion rod 17 is inserted into the ground, thereby increasing the grounding depth of the base 10 and further improving the support effect on the column 1.

[0040] Reference Figure 4 A vertical plate 18 is fixedly connected to the top of the base 10, a threaded rod 19 is threadedly connected to the inner thread of the vertical plate 18, a handle is threadedly connected to the top of the threaded rod 19, an end of the threaded rod 19 away from the handle passes through the vertical plate 18 and is rotatably connected to a resistance plate 20, a through hole 27 is opened at the top of the base 10, and the resistance plate 20 and the through hole 27 are slidably arranged.

[0041] The bottom of the abutment plate 20 is fixedly connected with a metal plate 21 , and a surface of the metal plate 21 close to the rotating plate 15 is configured as a rough metal surface.

[0042] In addition, an auxiliary rod 22 is fixedly connected to the top of the abutment plate 20 . The top of the auxiliary rod 22 passes through the vertical plate 18 . The auxiliary rod 22 is slidably connected to the vertical plate 18 .

[0043] During transportation, the threaded rod 19 is driven to move by rotating the handle, and the movement of the threaded rod 19 causes the contact plate 20 to pass through the through hole 27 to contact and fix the rotating plate 15, thereby reducing the risk of the rotating plate 15 being damaged due to collision with other objects during transportation. When the contact plate 20 is close to the rotating plate 15, the friction between the contact plate 20 and the rotating plate 15 is increased by the metal plate 21, thereby improving the fixing effect of the rotating plate 15. When the contact plate 20 moves, the auxiliary rod 22 provides the contact plate 20 with an additional support point, so that the contact plate 20 remains stable when moving.

[0044] Reference Figure 2 and Figure 3 The buffer mechanism includes a slider 23 fixedly connected to one side of the fixed plate 3, a slide groove 24 is provided inside the fixed block 2, the slider 23 is slidably connected to the slide groove 24, a buffer block 25 is provided inside the slide groove 24, and reinforcement blocks 26 are fixedly connected to both ends of the fixed plate 3, and the end of the reinforcement block 26 away from the fixed plate 3 is fixedly connected to the corrugated beam guardrail body 5.

[0045] When the corrugated beam guardrail body 5 collides, the corrugated beam drives the connecting block 4 to move, the connecting block 4 drives the fixing plate 3 to move, and the fixing plate 3 drives the slider 23 to enter the interior of the slide groove 24, so that the slider 23 contacts the buffer block 25. The buffer block 25 is made of polyurethane and has a high energy absorption capacity, which can effectively reduce the impact force during the collision, so that the impact force becomes smaller after the vehicle contacts the corrugated beam guardrail body 5, thereby protecting the corrugated beam guardrail body 5.

[0046] Working principle: Move the column 1 to a suitable position, then place the corrugated beam guardrail body 5 on one side of the fixed plate 3, and then threadably connect it to the corrugated beam guardrail body 5 through the connecting block 4, so that the corrugated beam guardrail body 5 is fixed on one side of the connecting block 4. When impacted, the corrugated beam guardrail body 5 is deformed to absorb energy, thereby protecting the vehicle and the driver and passengers. Turn the telescopic cylinder 8 to a suitable angle, and then slide the telescopic rod 9 inside the telescopic cylinder 8. The movement of the telescopic rod 9 will drive the base 10 to move downward, so that the base 10 contacts the ground. The column 1 is supported by the base 10, the telescopic rod 9 and the telescopic cylinder 8, thereby improving the stability of the column 1 when impacted. By passing the bolt 11 through the telescopic cylinder 8 and threadably connecting it to the threaded groove 12 on the telescopic rod 9, the position of the telescopic rod 9 can be fixed, thereby improving the flexibility and applicability of fixing the column 1.

[0047] Turning the handle drives the threaded rod 19 to move, and the movement of the threaded rod 19 allows the abutment plate 20 to pass through the through hole 27 to abut and fix the rotating plate 15, thereby reducing the risk of the rotating plate 15 being damaged due to collision with other objects during transportation. When the corrugated beam guardrail body 5 collides, the corrugated beam drives the connecting block 4 to move, the connecting block 4 drives the fixed plate 3 to move, and the fixed plate 3 drives the slider 23 to enter the interior of the slide groove 24, so that the slider 23 abuts against the buffer block 25. The buffer block 25 is made of polyurethane and has a high energy absorption capacity, thereby reducing the impact force of the collision.
