Description

Technical Field

[0001] The invention belongs to the technical field of guardrails, and particularly relates to a high-strength impact-resistant traffic safety guardrail. Background Art

[0002] Traffic safety guardrails are protective facilities used at the edges of traffic roads, in the central isolation belts or in dangerous areas, aiming to prevent vehicles from colliding, rolling over or straying into dangerous areas and ensuring road traffic safety. According to different installation positions, traffic guardrails can be divided into highway guardrails, bridge guardrails, tunnel guardrails, etc. They are usually made of durable materials such as metal, plastic, and concrete, and have the characteristics of being strong and durable and impact-resistant. The design of traffic safety guardrails takes into account factors such as protection effect, visual recognition, and aesthetics. At the same time, they should also have characteristics such as rust prevention and corrosion resistance to meet the usage requirements under different climate conditions.

[0003] Conventional traffic guardrails are mainly composed of metal guardrails, which generally consist of horizontal guardrails and columns. When a collision occurs, the impact is mainly absorbed by the deformation of the horizontal guardrails themselves. However, the traditional guardrails have a limited range of lateral deformability, resulting in the breakage of the guardrails and the occurrence of safety accidents before the impact force is completely absorbed. At the same time, they cannot be automatically reset during minor collisions.

[0004] At the same time, traditional guardrails mainly rely on the columns at the bottom and the horizontal guardrails to absorb the impact force during impact absorption. The entire guardrail cannot be supported during the absorption process, resulting in the risk of the guardrail falling off and unable to adjust different support angles according to the impact force. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-strength impact-resistant traffic safety guardrail to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A high-strength impact-resistant traffic safety guardrail, including a guardrail assembly and bases arranged at equal distances at the bottom of the guardrail assembly. The guardrail assembly includes a guardrail body, which is hollow and internally installed with reinforcing ribs. A column is fixedly installed on the front side of the top of the base, and the top of the column is connected to the bottom of the guardrail body. Extension rails are installed at the rear ends of the bases. A longitudinal rail is fixedly installed in the middle of the top of the base, and a transverse rail is fixedly installed at the top of the longitudinal rail. Transverse guide blocks are movably clamped inside the transverse rails. The transverse guide blocks move back and forth relative to the longitudinal rail. A sharing frame is fixedly installed at the front end of the transverse guide block, and the front end of the sharing frame is connected to the rear end of the guardrail body. A buffer assembly is installed at the bottom of the transverse guide block, and a support assembly is installed at the rear end of the buffer assembly. The support assembly is movably clamped with the extension rail;

[0007] When the guardrail assembly is stressed, it drives the lateral guide block to displace backward and completes buffering under the action of the buffer assembly, and acts on the support assembly to complete the adjustment of the support angle.

[0008] During the installation of the device, the base needs to be installed between the base and the ground to ensure that the base is parallel to the ground, and at the same time maintain the parallel relationship between the guardrail assembly and the ground to complete the installation process of the guardrail.

[0009] As a further technical solution of the present invention, the buffer assembly includes a first fixed seat, one end of the first fixed seat is connected to the rear end of the lateral guide block, and the other end of the first fixed seat away from the lateral guide block is movably connected to a connecting rod through a rotating shaft, and the other end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0010] As a further technical solution of the present invention, longitudinal guide blocks are fixedly installed at the ends of the second fixed seats away from the connecting rods. The longitudinal guide blocks are movably clamped with the longitudinal guide rails, and the longitudinal guide blocks displace up and down relative to the longitudinal guide rails.

[0011] As a further technical solution of the present invention, the buffer assembly further includes an oil storage pipe. The bottom end of the oil storage pipe is connected to the top end of the base. Oil delivery pipes are fixedly communicated at the front positions near the bottom ends of the oil storage pipes. The ends of the oil delivery pipes away from the oil storage pipes are fixedly communicated with a temporary storage box.

[0012] As a further technical solution of the present invention, piston plates are movably sleeved inside the oil storage pipes. Piston rods are fixedly installed at the top ends of the piston plates. The top ends of the piston rods penetrate through the top ends of the oil storage pipes and are connected to the bottom ends of the longitudinal guide blocks. Limiting springs are movably sleeved on the outer sides of the piston rods. The upper and lower ends of the limiting springs are respectively connected to one end of the inner cavity of the oil storage pipe and the top end of the piston plate.

[0013] When the guardrail body is impacted, the guardrail body then displaces backward, driving the first fixed seat to displace backward. At this time, the connecting rod deflects obliquely downward and exerts a thrust on the longitudinal guide block. At this time, the longitudinal guide block descends, driving the piston rod and the piston plate to displace downward. At this time, the limiting spring is stretched, and the impact is absorbed through the stretching of the limiting spring to complete the absorption process of the impact force.

[0014] By utilizing the cooperation between the transverse guide rail and the transverse guide block, and the cooperation between the transverse guide block and the buffer assembly, when the guardrail body is impacted, the impact force can be conducted to the buffer assembly and the transverse impact force can be converted into a longitudinal pressure. The impact force is absorbed through the action of the buffer assembly, and the longitudinal space is fully utilized to absorb the impact, reducing the fracture gap of the guardrail caused by the impact and improving safety.

[0015] As a further technical solution of the present invention, the interior of the temporary storage box is free of hydraulic oil in the initial state, the interior of the oil storage pipe is filled with hydraulic oil, and when the lateral guide block moves, the hydraulic oil inside the oil storage pipe is pressed into the interior of the temporary storage box.

[0016] When the piston plate moves downward, the hydraulic oil located inside the oil storage pipe is subjected to pressure accordingly. Under the action of the pressure, the hydraulic oil inside the oil storage pipe enters the interior of the temporary storage box through the oil delivery pipe and is temporarily stored inside the temporary storage box. When the external impact disappears, the hydraulic oil automatically flows back into the interior of the oil storage pipe due to gravity and drives the piston plate and the piston rod to move upward. At this time, the buffer assembly automatically resets and applies a forward thrust to the lateral guide block, prompting the guardrail body to reset and completing the automatic reset under slight deformation.

[0017] By utilizing the cooperation among the lateral guide block, the buffer assembly and the temporary storage box, the guardrail can absorb the impact force received while buffering through the buffer assembly and realize temporary storage through the transfer of hydraulic oil. At the same time, when the external impact force disappears, the buffer assembly and the lateral guide block are automatically reset by the reset of the hydraulic oil to apply a force to the guardrail body, realizing the automatic reset of the guardrail body after slight deformation, reducing the maintenance difficulty and improving the practicability of the device.

[0018] As a further technical solution of the present invention, the support assembly includes a third fixed seat, the front end of the third fixed seat is connected to the rear end of the longitudinal guide block, and the ends of the third fixed seat away from the longitudinal guide block are all movably connected with support rods through rotating shafts, and the ends of the support rods away from the third fixed seat are all movably connected with fourth fixed seats through rotating shafts.

[0019] As a further technical solution of the present invention, adjusting blocks are fixedly installed at the bottom ends of the fourth fixed seats, the adjusting blocks are movably clamped with the extension guide rails, the adjusting blocks move back and forth relative to the extension guide rails, and auxiliary support seats are installed on both the left and right sides of the fourth fixed seats.

[0020] As a further technical solution of the present invention, when the lateral guide block moves backward, the longitudinal guide block descends and drives the auxiliary support seat to move backward to complete the adjustment of the support angle.

[0021] At the same time, when the longitudinal guide block moves downward, the third fixed seat moves downward accordingly and drives the support rod to deflect backward. At this time, a thrust can be applied to the adjusting block and drive the adjusting block to move relative to the extension guide rail. At this time, the auxiliary support seats at both ends of the adjusting block move backward, and the support angle of the device is adjusted accordingly to complete the follow-up adjustment of the support angle.

[0022] By utilizing the cooperation between the buffer component and the support component, that is, while the device buffer is achieved through the buffer component, the adjustment process of the support angle can be automatically completed through the support component. The entire adjustment process can be automatically completed. When the device is subjected to a small impact, the entire guardrail can be assisted in supporting through the change of the support angle, reducing the risk of the guardrail falling off and improving safety.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) By utilizing the cooperation between the horizontal guide rail and the horizontal guide block, and the cooperation between the horizontal guide block and the buffer component, when the guardrail body is impacted, the impact force can be transmitted to the buffer component and the horizontal impact force can be transformed into a longitudinal pressure. The impact force is absorbed through the action of the buffer component, and the longitudinal space is fully utilized to absorb the impact, reducing the fracture gap of the guardrail caused by the impact and improving safety.

[0025] (2) By utilizing the cooperation between the horizontal guide block, the buffer component and the temporary storage box, while the guardrail is buffered by the buffer component, the impact force received can be absorbed and temporarily stored through the transfer of hydraulic oil. At the same time, when the external impact force disappears, the buffer component and the horizontal guide block are automatically reset by the reset of the hydraulic oil to apply a force to the guardrail body, realizing the automatic reset of the guardrail body after a small deformation, reducing the maintenance difficulty and improving the practicability of the device.

[0026] (3) By utilizing the cooperation between the buffer component and the support component, that is, while the device buffer is achieved through the buffer component, the adjustment process of the support angle can be automatically completed through the support component. The entire adjustment process can be automatically completed. When the device is subjected to a small impact, the entire guardrail can be assisted in supporting through the change of the support angle, reducing the risk of the guardrail falling off and improving safety.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1 to 7 shown, in the embodiment of the present invention, a high-strength impact-resistant traffic safety guardrail includes a guardrail component 1 and a base 2 arranged at equal distances at the bottom end of the guardrail component 1. The guardrail component 1 includes a guardrail body 101, the guardrail body 101 is hollow and internally installed with a reinforcing rib 102. The front side of the top end of the base 2 is fixedly installed with a column 4, the top end of the column 4 is connected to the bottom end of the guardrail body 101. Extended guide rails 3 are installed at the rear ends of the base 2. A longitudinal guide rail 6 is fixedly installed in the middle of the top end of the base 2. A transverse guide rail 5 is fixedly installed at the top end of the longitudinal guide rail 6. Transverse guide blocks 8 are movably clamped inside the transverse guide rail 5. The transverse guide blocks 8 are displaced back and forth relative to the longitudinal guide rail 6. A sharing frame 7 is fixedly installed at the front end of the transverse guide block 8. The front end of the sharing frame 7 is connected to the rear end of the guardrail body 101. A buffer component 9 is installed at the bottom end of the transverse guide block 8. A support component 11 is installed at the rear end of the buffer component 9. The support component 11 is movably clamped with the extended guide rail 3;

[0037] After the guardrail component 1 is stressed, it drives the transverse guide block 8 to displace backward and completes buffering under the action of the buffer component 9, and acts on the support component 11 to complete the adjustment of the support angle.

[0038] During the installation of the device, the base 2 needs to be installed between the base and the ground to ensure that the base 2 is parallel to the ground. At the same time, the parallel relationship between the guardrail assembly 1 and the ground is maintained to complete the installation process of the guardrail.

[0039] As Figure 2 and Figure 4 as well as Figure 6 shown, the buffer assembly 9 includes a first fixing seat 901. One end of the first fixing seat 901 is connected to the rear end of the lateral guide block 8. One end of the first fixing seat 901 away from the lateral guide block 8 is pivotally connected to a connecting rod 903 through a rotating shaft. One end of the connecting rod 903 away from the first fixing seat 901 is pivotally connected to a second fixing seat 902 through a rotating shaft. One end of the second fixing seat 902 away from the connecting rod 903 is fixedly installed with a longitudinal guide block 904. The longitudinal guide block 904 is movably clamped with the longitudinal guide rail 6. The longitudinal guide block 904 moves up and down relative to the longitudinal guide rail 6. The buffer assembly 9 further includes an oil storage pipe 905. The bottom end of the oil storage pipe 905 is connected to the top end of the base 2. The front positions of the oil storage pipe 905 near the bottom end are fixedly communicated with an oil delivery pipe 909. One end of the oil delivery pipe 909 away from the oil storage pipe 905 is fixedly communicated with a temporary storage box 10. A piston plate 906 is movably sleeved inside the oil storage pipe 905. A piston rod 907 is fixedly installed at the top end of the piston plate 906. The top end of the piston rod 907 penetrates through the top end of the oil storage pipe 905 and is connected to the bottom end of the longitudinal guide block 904. A limiting spring 908 is movably sleeved on the outer side of the piston rod 907. The upper and lower ends of the limiting spring 908 are respectively connected to one end of the inner cavity of the oil storage pipe 905 and the top end of the piston plate 906.

[0040] Embodiment: When the guardrail body 101 is impacted, at this time, the guardrail body 101 moves backward accordingly, and drives the first fixing seat 901 to move backward. At this time, the connecting rod 903 deflects obliquely downward accordingly, and applies a thrust to the longitudinal guide block 904. At this time, the longitudinal guide block 904 descends accordingly, and drives the piston rod 907 and the piston plate 906 to move downward. At this time, the limiting spring 908 is stretched accordingly, and the impact is buffered through the stretching of the limiting spring 908 to complete the process of absorbing the impact force.

[0041] By utilizing the cooperation between the transverse guide rail 5 and the lateral guide block 8, and the cooperation between the lateral guide block 8 and the buffer assembly 9, when the guardrail body 101 is impacted, the impact force can be transmitted to the buffer assembly 9 and the lateral impact force can be converted into a longitudinal pressure. Through the action of the buffer assembly 9, the impact force is absorbed, and the longitudinal space is utilized to fully absorb the impact, reduce the fracture gap of the guardrail caused by the impact, and improve safety.

[0042] As Figure 1 and Figure 2 as well as Figure 6As shown, there is no hydraulic oil inside the temporary storage box 10 in the initial state. The inside of the oil storage pipe 905 is filled with hydraulic oil. When the lateral guide block 8 moves, the hydraulic oil inside the oil storage pipe 905 is pressed into the inside of the temporary storage box 10.

[0043] When the piston plate 906 moves downward, the hydraulic oil located inside the oil storage pipe 905 is subjected to pressure at this time. Under the action of the pressure, the hydraulic oil inside the oil storage pipe 905 enters the inside of the temporary storage box 10 through the oil delivery pipe 909 and is temporarily stored inside the temporary storage box 10. When the external impact disappears, at this time the hydraulic oil automatically flows back into the inside of the oil storage pipe 905 due to gravity and drives the piston plate 906 and the piston rod 907 to move upward. At this time, the buffer assembly 9 automatically resets and applies a forward thrust to the lateral guide block 8, prompting the guardrail body 101 to reset and completing the automatic reset under small deformation.

[0044] By utilizing the cooperation among the lateral guide block 8, the buffer assembly 9, and the temporary storage box 10, the guardrail can absorb the impact force received while buffering through the buffer assembly 9 and achieve temporary storage through the transfer of hydraulic oil. At the same time, when the external impact force disappears, the buffer assembly 9 and the lateral guide block 8 are automatically reset by the reset of the hydraulic oil to apply a force to the guardrail body 101, realizing the automatic reset of the guardrail body 101 after small deformation, reducing the maintenance difficulty, and improving the practicality of the device.

[0045] As Figure 2 and Figure 4 as well as Figure 7 shown, the support assembly 11 includes a third fixed seat 111. The front end of the third fixed seat 111 is connected to the rear end of the longitudinal guide block 904. One end of the third fixed seat 111 away from the longitudinal guide block 904 is movably connected to a support rod 113 through a rotating shaft. One end of the support rod 113 away from the third fixed seat 111 is movably connected to a fourth fixed seat 112 through a rotating shaft. An adjusting block 114 is fixedly installed at the bottom end of the fourth fixed seat 112. The adjusting block 114 is movably clamped with the extension guide rail 3. The adjusting block 114 moves forward and backward relative to the extension guide rail 3. Auxiliary support seats 115 are installed on both the left and right sides of the fourth fixed seat 112. When the lateral guide block 8 moves backward, the longitudinal guide block 904 descends and drives the auxiliary support seat 115 to move backward to complete the adjustment of the support angle.

[0046] Embodiment: At the same time, when the longitudinal guide block 904 moves downward, the third fixed seat 111 moves downward accordingly and drives the support rod 113 to deflect backward. At this time, a thrust can be applied to the adjusting block 114 and drive the adjusting block 114 to move relative to the extension guide rail 3. At this time, the auxiliary support seats 115 at both ends of the adjusting block 114 move backward accordingly, and the support angle of the device is adjusted accordingly to complete the follow-up adjustment of the support angle.

[0047] By making use of the cooperation between the buffer assembly 9 and the support assembly 11, that is, while the device buffer is realized through the buffer assembly 9, the adjustment process of the support angle can be automatically completed through the support assembly 11. The whole adjustment process can be automatically completed. When the device is subjected to a small impact, the entire guardrail can be assisted in supporting through the change of the support angle, reducing the risk of the guardrail falling off and improving safety.

[0048] Working principle and usage process:

[0049] During the installation of the device, the base 2 needs to be installed with the ground to ensure that the base 2 is parallel to the ground, and at the same time, the parallel relationship between the guardrail assembly 1 and the ground is maintained to complete the installation process of the guardrail;

[0050] When the guardrail body 101 is subjected to an impact force, at this time, the guardrail body 101 moves backward, and drives the first fixing seat 901 to move backward. At this time, the connecting rod 903 deflects obliquely downward and exerts a thrust on the longitudinal guide block 904. At this time, the longitudinal guide block 904 descends, and drives the piston rod 907 and the piston plate 906 to move downward. At this time, the limit spring 908 is stretched, and the impact force is absorbed through the stretching of the limit spring 908 to complete the absorption process of the impact force;

[0051] When the piston plate 906 moves downward, the hydraulic oil inside the oil storage pipe 905 is subjected to pressure at this time. Under the pressure, the hydraulic oil inside the oil storage pipe 905 enters the inside of the temporary storage box 10 through the oil delivery pipe 909 and is temporarily stored inside the temporary storage box 10. When the external impact disappears, at this time, the hydraulic oil automatically flows back into the oil storage pipe 905 due to gravity, and drives the piston plate 906 and the piston rod 907 to move upward. At this time, the buffer assembly 9 automatically resets, and exerts a forward thrust on the transverse guide block 8, prompting the guardrail body 101 to reset, and completing the automatic reset under minor deformation;

[0052] At the same time, when the longitudinal guide block 904 moves downward, at this time, the third fixing seat 111 moves downward, and drives the support rod 113 to deflect backward. At this time, a thrust can be exerted on the adjusting block 114, and the adjusting block 114 is driven to displace relative to the extension guide rail 3. At this time, the auxiliary support seats 115 at both ends of the adjusting block 114 move backward, and the support angle of the device is adjusted, completing the follow-up adjustment of the support angle.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
