Description

Technical Field

[0001] The utility model relates to the technical field of high-speed guardrails, in particular to a buffer-type high-speed guardrail plate. Background Art

[0002] Highway guardrails play a pivotal role in ensuring road traffic safety. Highway guardrails can limit the driving range of vehicles, prevent vehicles from deviating from normal lanes, and ensure traffic order and smooth roads. In addition, highway guardrails can also absorb part of the collision energy and reduce the damage to vehicles and personnel caused by accidents.

[0003] In the prior art, a buffer highway guardrail proposed by publication number CN219033039U includes a base, a support column, a lower fixed collar, a lower mounting collar, a tension support spring, an upper mounting collar, an upper fixed collar, a rotating bolt, a connecting rod, an upper corrugated bar, a tension spring, and a lower corrugated bar. A support column is installed on the base, and a lower fixed collar and an upper fixed collar are arranged on the support column. A lower mounting collar and an upper mounting collar are arranged between the lower fixed collar and the upper fixed collar, and the lower mounting collar and the upper mounting collar are connected to form an integrated structure through a tension support spring. The connecting rods are connected through rotating bolts, and a tension spring is arranged between the upper corrugated bar and the lower corrugated bar. The upper corrugated bar and the lower corrugated bar are respectively connected to the lower mounting collar and the upper mounting collar through the connecting rod. The utility model has a simple structure and is easy to install. The buffering effect of the corrugated bar can be improved by the tension support spring and the tension spring, and effective buffering protection is provided to vehicles and driving personnel.

[0004] This application can improve the buffering effect of the corrugated guardrail through tension support springs and tension springs, and provide effective buffering protection for vehicles and passengers. However, when the vehicle collides with the guardrail, the angle is not fixed. If the vehicle collides with the end of the corrugated guardrail, the end of the corrugated guardrail is subjected to force. Since the impact force is not parallel to the connecting rod, the impact force buffered by the support spring and tension spring is small, and the corrugated guardrail is easily detached from the end of the connecting rod, resulting in reduced buffering effect of the guardrail. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a buffer-type high-speed guardrail plate so as to solve the technical problems mentioned in the above-mentioned background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A buffer-type high-speed guardrail comprises two main bases and two main columns, wherein the two main columns are respectively fixedly mounted on the top sides of the two main bases, a central column is arranged between the two main columns, a columnar clamping block is respectively arranged between the central column and the two main columns via a first connecting member and a second connecting member, a fixing rod is fixedly connected between the two ends of the columnar clamping block, a torsion spring is fixedly connected to the outer peripheral wall of the fixing rod, an outer tube is fixedly connected to the outer side of the torsion spring, and the end of the outer tube is rotatably connected to the columnar clamping block.

[0009] In a preferred example, the utility model can be further configured as follows: a first cavity tube is fixedly connected to the outer peripheral wall of the rotating ring, the end piston of the first cavity tube is connected to a first piston rod, the first piston rod close to the main column is connected to the columnar clamp block, the first piston rod close to the central column is fixedly connected to the outer tube, and a through hole is opened at the end of the first cavity tube.

[0010] In a preferred example, the utility model can be further configured as follows: the second connecting member includes a number of notches, the notches are opened on the central column and located between two adjacent outer grooves and on the main column away from the outer grooves, and a positioning ring is rotatably connected in the notches.

[0011] In a preferred example, the utility model can be further configured as follows: a second cavity is fixedly connected to the outer peripheral wall of the positioning ring, and the end piston of the second cavity is connected to a second piston rod, wherein the two opposite ends of the second piston rod are respectively fixedly connected to the corresponding cylindrical clamp block and outer tube.

[0012] In a preferred example, the utility model can be further configured as follows: an air hole is opened on the peripheral wall outside the second cavity tube, and the opening direction of the air hole faces upward.

[0013] In summary, the utility model includes at least one of the following beneficial technical effects:

[0014] 1. This buffer-type high-speed guardrail can buffer the torsion force of the torsion spring when in use, and cooperate with the first connecting member and the second connecting member to perform multiple buffering and unloading, so as to protect the vehicle from running off the road and causing secondary damage. In addition, after multiple positions of the high-speed guardrail are impacted, the first connecting member and the second connecting member can cooperate with the torsion spring to buffer and unload the force, so as to avoid a significant decrease in the buffering effect due to different impact positions of the guardrail;

[0015] 2. This buffer-type highway guardrail, when in use, has its main base buried on the side of the highway, the main base and the main column are made in one piece, wherein when the center column is impacted, the center column will move to the outside of the highway due to the impact, and the movement of the center column will pull the first connecting frame and the second connecting member, thereby driving the corresponding outer tube and the columnar clamping block to rotate, and then driving the corresponding torsion spring to rotate, and buffering is performed by the reaction force of the torsion spring, and further buffering is performed by the negative pressure of the first connecting member and the second connecting member;

[0016] 3. In this buffering high-speed guardrail, when the first piston rod makes a piston movement in the first cavity, negative pressure will be quickly generated in the first cavity. In addition, the diameter of the through hole is small, so the speed at which air enters the first cavity is limited. When the first cavity generates negative pressure due to the piston movement of the first piston rod and gradually absorbs air, the impact is buffered and the force is unloaded at the same time until the air pressure in the first cavity is the same as the outside air pressure, thereby achieving the effect of buffering and unloading force, and then cooperates with the second connecting piece to perform further buffering to achieve the effect of protecting the vehicle.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 4 The utility model discloses a buffer-type high-speed guardrail, comprising two main bases 1 and two main columns 2, the two main columns 2 are respectively fixedly installed on the top sides of the two main bases 1, a central column 4 is arranged between the two main columns 2, a columnar clamping block 6 is respectively arranged between the central column 4 and the two main columns 2 through a first connecting member 5 and a second connecting member 3, a fixing rod 7 is fixedly connected between the two ends of the columnar clamping block 6, a torsion spring 8 is fixedly connected to the outer peripheral wall of the fixing rod 7, an outer tube 9 is fixedly connected to the outer side of the torsion spring 8, and the end of the outer tube 9 is rotatably connected to the columnar clamping block 6.

[0026] In this embodiment, the main base 1 is buried in the side of the highway when in use. The main base 1 and the main column 2 are made as one piece. When the center column position is impacted, the center column will move to the outside of the highway due to the impact. As the center column moves, the first connecting frame and the second connecting member 3 will be pulled, thereby driving the corresponding outer tube 9 and the columnar clamp 6 to rotate, and then driving the corresponding torsion spring 8 to rotate, and buffering is performed by the reaction force of the torsion spring 8, and further buffering is performed by the negative pressure of the first connecting member 5 and the second connecting member 3.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the first connecting member 5 includes a number of outer grooves 10, and the number of outer grooves 10 are respectively opened on the outer peripheral walls of the main column 2 and the central column 4, a swivel 11 is rotatably connected in the outer groove 10, and a first cavity 12 is fixedly connected to the outer peripheral wall of the swivel 11, and the end piston of the first cavity 12 is connected to a first piston rod 13, the first piston rod 13 close to the main column 2 is connected to the columnar clamp 6, and the first piston rod 13 close to the central column 4 is fixedly connected to the outer tube 9, and a through hole 14 is opened at the end of the first cavity 12.

[0028] In this embodiment, when the position of the first positioning member between the central column 4 and the main column 2 is collided, the corresponding columnar clamp 6 or the first cavity tube 12 located on both sides of the columnar clamp 6 will be pushed preferentially when collided, and the columnar clamp 6 will be moved to the outside of the highway at this time. During the movement, the angle between the two first piston rods 13 gradually changes. At the same time, as the columnar clamp 6 moves, the two first piston rods 13 will be pulled, and the central column 4 will be pulled at the same time. When the angle between the two first piston rods 13 changes, the outer tube 9 and the columnar clamp 6 will be driven to rotate, thereby driving the internal torsion spring 8 to rotate. At the same time, the first piston rod 13 will perform piston motion in the first cavity tube 12, and the reaction force of the torsion spring 8 will be used for buffering.

[0029] In addition, when the first piston rod 13 performs piston movement in the first cavity 12, negative pressure will be quickly generated in the first cavity 12. The diameter of the through hole 14 provided in addition is relatively small, so the speed at which air enters the first cavity 12 is limited. When the first cavity 12 generates negative pressure due to the piston movement of the first piston rod 13 and gradually absorbs air, the impact is buffered and force is unloaded at the same time until the air pressure in the first cavity 12 is the same as the external air pressure, thereby achieving the effect of buffering and unloading force, and then cooperating with the second connecting member 3, further buffering is performed to achieve the effect of protecting the vehicle.

[0030] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the second connecting member 3 includes a plurality of notches 15, and the notches 15 are opened on the central column 4 and located between two adjacent outer grooves 10 and on the main column 2 away from the outer groove 10. A positioning ring 16 is rotatably connected in the notch 15, and a second cavity 17 is fixedly connected to the outer peripheral wall of the positioning ring 16. The end piston of the second cavity 17 is connected to a second piston rod 18, wherein the ends of the two opposite second piston rods 18 are fixedly connected to the corresponding cylindrical clamping block 6 and the outer tube 9 respectively, and an air hole 19 is opened on the peripheral wall outside the second cavity 17, and the opening direction of the air hole 19 is upward.

[0031] In this embodiment, when the second connecting member 3 is impacted, the principle is the same as that of the first connecting member 5. After the impact, the cylindrical clamp 6 is driven to move to the outside of the highway, thereby driving the second cavity 17 and the second piston rod 18 to perform piston movement, and causing the angles of two adjacent second piston rods 18 to change. The torsion spring 8 and the negative pressure in the second cavity 17 are used to buffer and unload the force, and air is sucked through the set air hole 19 to achieve the effect of buffering and unloading the force. Combined with the first connecting member 5, multiple buffering is performed to protect the vehicle from running off the road.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
