Description

Technical Field

[0001] The present invention relates to the technical field of guardrails, and particularly relates to a PVC column reinforced guardrail. Background Art

[0002] A guardrail is a facility used for boundary marking, safety protection or restricted passage, usually composed of materials such as metal, wood, plastic or concrete. They are widely used in places such as roads, bridges, construction sites, factories, public places, waters, etc. to provide safety protection and indication. Guardrails are usually installed on both sides of the road. The guardrail can intercept the vehicle to prevent the vehicle from rushing out of the road. However, when the guardrail is subjected to a strong collision, it will bend and break, resulting in serious damage.

[0003] Currently, there are already some existing technologies that can prevent the guardrail from breaking when it is subjected to a large impact force. For example, the patent publication number is CN217760397U. Its main technical means is that the L-shaped steel can reinforce the connection between the base and the guardrail, and at the same time, the four triangular reinforcement blocks can support in four directions. The triangular reinforcement blocks have strong stability. When the guardrail is subjected to a large impact force, the connection between the guardrail and the base will not break, improving the rigidity of the guardrail. After analysis, the disadvantage of this technical solution is that when a collision occurs, the vehicle impacts the PVC column, which is extremely likely to cause the PVC column to bend. There is no anti-bending structure provided for the PVC column. After the PVC column bends, it is extremely likely to cause damage to the oncoming vehicle on the other side. Based on this, the present invention provides a PVC column reinforced guardrail with a simple and ingenious structure, which can automatically strengthen the PVC column at the collision part when the vehicle collides with the guardrail. Summary of the Invention

[0004] The purpose of the present invention is to provide a PVC column reinforced guardrail for the deficiencies of the existing technology, so as to solve the technical problem that when a collision occurs, the PVC column cannot be automatically strengthened and protected against bending, resulting in the PVC column being extremely likely to bend and cause damage to the oncoming vehicle.

[0005] The purpose of the present invention can be achieved by the following technical solutions: A PVC column reinforced guardrail, comprising: A base, which is fixed on the road surface, and a PVC column body is vertically installed thereon. An assembly part is provided on the base, and adjacent two bases are connected through the assembly part; and Impact plates, several impact plates are all slidably installed on the PVC column body. A number of anti-folding blocks are slidably installed on the PVC column body. The impact plates and the anti-folding blocks are respectively installed on both sides of the PVC column body. Each impact plate is linked with two anti-folding blocks through a transmission assembly. When a vehicle impacts the impact plate, the impact plate moves towards the PVC column body and drives the two anti-folding blocks to move towards each other through the transmission assembly, so as to splice on the other side of the PVC column body corresponding to the impact plate.

[0006] As a further solution of the present invention: The transmission assembly includes: Step-down plates, two step-down plates are both slidably installed on the PVC column body, and both two step-down plates are arranged between the PVC column body and the impact plate. Both two step-down plates are slidably matched with the impact plate; Fixed blocks, two fixed blocks are both fixedly installed on the PVC column body, and the two step-down plates are located between the two fixed blocks. The two fixed blocks are respectively connected with the two step-down plates through two first elastic members; and Link rods, the step-down plates and the anti-folding blocks on the same side of the impact plate are respectively rotatably connected to both ends of the link rod, and the link rod is rotatably installed on the PVC column body.

[0007] As a further solution of the present invention: The impact plate is in contact with both two step-down plates. A first inclined surface is arranged on the impact plate. Second inclined surfaces are symmetrically arranged on the opposite surfaces of the two step-down plates. The first inclined surface and the two second inclined surfaces are both slidably matched; when the impact plate moves towards the PVC column body, the first inclined surface and the two second inclined surfaces slide relative to each other, driving the two step-down plates to move away from each other.

[0008] As a further solution of the present invention: A reinforcing rib is installed on the PVC column body corresponding to between the two transmission assemblies.

[0009] As a further solution of the present invention: A support rod assembly is connected between the base and the PVC column body.

[0010] As a further solution of the present invention: The support rod assembly includes a first support rod, a second support rod and several intermediate support rods arranged between the two. The first support rod, the second support rod and the several intermediate support rods are all inclinedly arranged, and the bottoms are all slidably installed on the base.

[0011] As a further solution of the present invention: The impact plate is connected with the support rod assembly through a rotating assembly; when the impact plate moves towards the PVC column body, the impact plate drives the support rod assembly to rotate through the rotating assembly until the first support rod, the second support rod and the several intermediate support rods are in contact with each other to support the side of the PVC column body where the anti-folding block is installed.

[0012] As a further solution of the present invention: The rotating assembly includes: A swivel ring, which is rotatably installed outside the PVC column body. The first support rod and several intermediate support rods are all slidably installed on the swivel ring, and the second support rod is fixedly installed on the swivel ring; A stop strip, which is fixed on the base and slidably cooperates with the swivel ring. The stop strip is located between the first support rod and the second support rod. Second elastic members are connected between the first support rod and the intermediate support rods, between adjacent intermediate support rods, and between the intermediate support rods and the second support rod; and A toothed ring, which is coaxially and fixedly connected with the swivel ring and meshes with a rack slidably installed on the base. The rack is fixedly connected with an impact plate through a guide rod.

[0013] Advantages of the present invention: (1) In the present invention, when a vehicle collides with the guardrail and moves towards the PVC column body, the impact plate cooperates with the transmission assembly to drive the two anti-bending blocks on the back of the PVC column body to move towards each other, so as to splice on the other side of the PVC column body corresponding to the impact plate. The moving anti-bending blocks can first strengthen the protection on both sides of the impact point, reduce the possibility of bending in the area near the impact point of the PVC column body, and finally move to the opposite position of the impact point of the PVC column body for strengthening protection. The moving direction of the anti-bending blocks is opposite to the direction of impact force diffusion, which can reduce the degree of bending deformation diffusion, minimize the bending area of the PVC column body to the greatest extent, and can automatically strengthen the collision part when the vehicle collides with the guardrail; (2) In the present invention, when the vehicle impacts the impact plate, the impact plate is squeezed between the two pressure-reducing plates, and the two pressure-reducing plates move away from each other, and the first elastic member is squeezed, which can reduce the impact force generated by the impact and achieve absorption-type protection. Combined with the strengthened protection of the back of the impact point on the PVC column body after the two anti-bending blocks are attached, that is, adopting absorption-type protection combined with strengthened protection, on the basis of ordinary protection of the PVC column body, it can also reduce the degree of deformation diffusion of the impact point of the PVC column body to the surrounding area, so as to automatically and adaptively perform anti-bending protection on the guardrail when a vehicle collision occurs; (3) In the present invention, when the impact plate moves towards the PVC column body, the impact plate drives the support rod assembly to rotate through the rotating assembly, that is, the first support rod, the second support rod and several intermediate support rods all rotate in the same direction until they are attached to each other and gather between one side of the PVC column body where the anti-bending block is installed and the base. It can instantaneously change the support position during a collision and strengthen the protection of the bottom of the PVC column body on the back of the impact point to avoid the fracture and separation between the bottom of the PVC column body and the base caused by the impact.

Detailed implementation manners

[0017] 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 belong to the protection scope of the present invention.

[0018] Please refer to Figures 1-6 as shown, the present invention is a PVC column reinforced guardrail, including: A base 1, which is fixed on the road surface, and a PVC column body 2 is vertically installed thereon. An assembly 9 is provided on the base 1, and adjacent two bases 1 are connected by the assembly 9; and Impact plates 3, a plurality of impact plates 3 are all slidably installed on the PVC column body 2. A plurality of anti-folding blocks 4 are slidably installed on the PVC column body 2, and the impact plates 3 and the anti-folding blocks 4 are respectively installed on both sides of the PVC column body 2. Each impact plate 3 is linked with two anti-folding blocks 4 through a transmission component 5; when a vehicle impacts the impact plate 3, the impact plate 3 moves towards the PVC column body 2, and drives the two anti-folding blocks 4 to move towards each other through the transmission component 5, so as to be spliced on the other side of the PVC column body 2 corresponding to the impact plate 3.

[0019] In one case of this embodiment, the assembly 9 can be connected by bolts, or other structural components capable of achieving connection can be selected, and specific limitations are not provided here.

[0020] In actual application of this embodiment, when the vehicle impacts the impact plate 3, the impact plate 3 moves towards the PVC column body 2. The impact plate 3 drives the two anti-fold blocks 4 to move towards each other through the transmission assembly 5, so as to splice on the other side of the PVC column body 2 corresponding to the impact plate 3, which can achieve enhanced protection for the PVC column body 2 and reduce the possibility of the PVC column body 2 being bent due to collision. It should be noted that in the initial state, the two anti-fold blocks 4 corresponding to the impact plate 3 are located on both sides of it. When the impact plate 3 moves towards the PVC column body 2, it drives these two anti-fold blocks 4 to move towards each other until they are spliced on the other side of the PVC column body 2 corresponding to the impact plate 3. During this process, the moving anti-fold blocks 4 can first strengthen the protection on both sides of the impact point, reduce the possibility of the PVC column body 2 being bent in the area near the impact point, and finally move to the opposite position of the impact point of the PVC column body 2. The moving direction of the anti-fold block 4 is opposite to the direction of the impact force diffusion, in order to reduce the degree of diffusion of the bending deformation and minimize the bending area of the PVC column body 2 to the greatest extent. Compared with fixedly installing a protective member on the back of the PVC column body 2, it can dynamically reduce the size of the bending area. For vehicle impact situations of different heights, the heights of several impact plates 3 are different, and all cooperate with two anti-fold blocks 4, which can adaptively and dynamically reduce the bending deformation according to the height of the impact point.

[0021] As Figures 1-4 shown, as a preferred embodiment of the present invention, the transmission assembly 5 includes: Step-down plates 501, both of the two step-down plates 501 are slidably installed on the PVC column body 2, and both of the two step-down plates 501 are arranged between the PVC column body 2 and the impact plate 3, and both of the two step-down plates 501 are slidably matched with the impact plate 3; Fixed blocks 502, both of the two fixed blocks 502 are fixedly installed on the PVC column body 2, and the two step-down plates 501 are located between the two fixed blocks 502. The two fixed blocks 502 are respectively connected to the two step-down plates 501 through two first elastic members 503; and Link 504, the step-down plate 501 and the anti-fold block 4 on the same side of the impact plate 3 are respectively rotatably connected to both ends of the link 504, and the link 504 is rotatably installed on the PVC column body 2.

[0022] In a case of this embodiment, the impact plate 3 is in contact with both of the two pressure-reducing plates 501. A first inclined surface 505 is provided on the impact plate 3, and second inclined surfaces 506 are symmetrically arranged on the opposite surfaces of the two pressure-reducing plates 501, and the first inclined surface 505 is in sliding fit with both of the two second inclined surfaces 506. When the impact plate 3 moves towards the PVC column body 2, the first inclined surface 505 and the two second inclined surfaces 506 slide relative to each other, driving the two pressure-reducing plates 501 to move away from each other.

[0023] Among them, the first elastic member 503 can be selected as Figure 3 the spring shown, and other elastic components can also be selected for replacement, such as silica gel columns, elastic sheets, etc., which are not specifically limited in this embodiment.

[0024] In the actual application of this embodiment, in the initial state, the two pressure-reducing plates 501 are in contact with each other, and at this time, the first elastic member 503 is in a free state. When the vehicle impacts the impact plate 3, the impact plate 3 moves towards the PVC column body 2, and the first inclined surface 505 and the two second inclined surfaces 506 slide relative to each other, that is, the impact plate 3 is squeezed between the two pressure-reducing plates 501, and the two pressure-reducing plates 501 move away from each other, and the first elastic member 503 is squeezed. This process can reduce the impact force generated by the impact and achieve absorption-type protection. When the two pressure-reducing plates 501 move away from each other, the two anti-bending blocks 4 can be driven to move towards each other through the two connecting rods 504 until the two anti-bending blocks 4 are in contact with each other, so as to strengthen the protection of the back surface of the impact point on the PVC column body 2, reduce the degree of diffusion of the deformation of the impact point on the PVC column body 2 to the surrounding area, and thus reduce the overall bending degree of the PVC column body 2, realizing the protection of the guardrail.

[0025] As Figures 1-4 shown, as a preferred embodiment of the present invention, a reinforcing rib 6 is installed on the PVC column body 2 corresponding to between the two transmission components 5. In the actual application, the reinforcing rib 6 can strengthen the protection of the area outside the moving area of the anti-bending block 4.

[0026] As Figures 1-6 shown, as a preferred embodiment of the present invention, a support rod assembly 7 is connected between the base 1 and the PVC column body 2.

[0027] In the actual application of this embodiment, the support rod assembly 7 can reinforce the connection between the base 1 and the PVC column body 2. When the guardrail is subjected to a large impact force, the connection between the base 1 and the PVC column body 2 will not break.

[0028] As Figures 1-6As shown, as a preferred embodiment of the present invention, the support rod assembly 7 includes a first support rod, a second support rod, and a plurality of intermediate support rods disposed therebetween. The first support rod, the second support rod, and the plurality of intermediate support rods are all inclined, and their bottoms are all slidably installed on the base 1.

[0029] In one case of this embodiment, the impact plate 3 is connected to the support rod assembly 7 through a rotating assembly 8; when the impact plate 3 moves towards the PVC column body 2, the impact plate 3 drives the support rod assembly 7 to rotate through the rotating assembly 8 until the first support rod, the second support rod, and the plurality of intermediate support rods are mutually attached to support the side of the PVC column body 2 where the anti-folding block 4 is installed.

[0030] In actual application of this embodiment, in the initial state, no impact occurs, and there are gaps between the first support rod and the intermediate support rods, between adjacent intermediate support rods, and between the intermediate support rods and the second support rod. The plurality of support rods are arranged in a circle, which can ensure the vertical stability of the PVC column body 2; when the impact plate 3 moves towards the PVC column body 2, the impact plate 3 drives the support rod assembly 7 to rotate through the rotating assembly 8, that is, the first support rod, the second support rod, and the plurality of intermediate support rods all rotate in the same direction until they are mutually attached and gather between the side of the PVC column body 2 where the anti-folding block 4 is installed and the base 1. It can instantaneously change the support position when a collision occurs, and strengthen the protection of the bottom of the PVC column body 2 on the back of the impact point to prevent the bottom of the PVC column body 2 from breaking and separating from the base 1 due to the impact.

[0031] As Figures 1-6 shown, as a preferred embodiment of the present invention, the rotating assembly 8 includes: A rotating ring 801, which is rotatably installed outside the PVC column body 2. The first support rod and the plurality of intermediate support rods are all slidably installed on the rotating ring 801, and the second support rod is fixedly installed on the rotating ring 801; A stop bar 802, which is fixed on the base 1 and is slidably matched with the rotating ring 801. The stop bar 802 is located between the first support rod and the second support rod. A second elastic member 803 is connected between the first support rod and the intermediate support rods, between adjacent intermediate support rods, and between the intermediate support rods and the second support rod; and A toothed ring 804, which is coaxially and fixedly connected to the rotating ring 801 and meshes with a rack 805 slidably installed on the base 1. The rack 805 is fixedly connected to the impact plate 3 through a guide rod 806.

[0032] In one case of this embodiment, the second elastic member 803 can be selected as the spring as Figure 5 shown, or other elastic components can be used for replacement, such as a silica gel column, a spring piece, etc. No specific limitation is made in this embodiment.

[0033] In practical application of this embodiment, when the vehicle impacts the impact plate 3, as the impact plate 3 moves towards the PVC column body 2, the guide rod 806 moves synchronously driven by the impact plate 3, then the rack 805 moves synchronously. Through meshing transmission, the toothed ring 804 is driven to rotate, and then the rotating ring 801 rotates synchronously, causing the second support rod to rotate synchronously and squeezing a number of second elastic members 803, driving the first support rod and a number of intermediate support rods to rotate in the same direction. The first support rod rotates towards the stop bar 802 until they are in contact. Subsequently, a number of intermediate support rods and the second support rod continue to rotate. During this process, the second elastic member 803 between the first support rod and the intermediate support rod is squeezed until the second elastic member 803 is squeezed to the maximum deformation degree. At this time, the intermediate support rod adjacent to the first support rod is in contact with it. Subsequently, it, the intermediate support rod and the second support rod continue to rotate, and so on, until the first support rod, the second support rod and a number of intermediate support rods are in contact with each other, as Figure 6 shown in the figure, so as to provide enhanced protection for the bottom of the PVC column body 2 on the back of the impact point.

[0034] The working principle of the present invention: In the above embodiment of the present invention, a PVC column reinforced guardrail is provided. When the vehicle collides with the guardrail, the impact plate 3 moving towards the PVC column body 2 cooperates with the transmission assembly 5 to drive two anti-bending blocks 4 on the back of the PVC column body 2 to move towards each other, so as to splice on the other side of the PVC column body 2 corresponding to the impact plate 3. The moving anti-bending blocks 4 can first strengthen the protection on both sides of the impact point, reducing the possibility of bending in the area near the impact point of the PVC column body 2. Finally, they move to the opposite position of the impact point of the PVC column body 2 for enhanced protection. The moving direction of the anti-bending blocks 4 is opposite to the direction of impact force diffusion, which can reduce the degree of bending deformation diffusion and minimize the bending area of the PVC column body 2 to the greatest extent.

[0035] The above has described a detailed description of an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
