Description

Technical Field

[0001] This utility model relates to the field of traffic guardrail technology, specifically to a road anti-collision corrugated guardrail. Background Technology

[0002] Corrugated beam steel guardrails are an important road traffic safety facility. They can absorb collision energy through their own elastic-plastic deformation and force out-of-control vehicles to change direction and return to the normal driving track, thereby minimizing injury to occupants and damage to vehicles.

[0003] Chinese patent CN215758728U discloses a novel highway guardrail, comprising multiple support posts installed on the side of the road, with corrugated protective panels mounted on the support posts. A connecting box for connecting the corrugated protective panels is installed on each support post, and the connecting box is fixed to the support post by bolts and tie rods. The connecting box contains a claw assembly that allows for quick assembly and disassembly of the corrugated protective panels by adjusting the bolts and tie rods. This invention improves the installation efficiency of the corrugated protective panels by using a connecting box at the connection point between the corrugated protective panels and the support posts, and by incorporating a claw assembly within the connecting box that can adjust the clamping of the corrugated protective panels with bolts. However, this guardrail has insufficient collision energy absorption capacity and is ill-suited for handling complex traffic accidents.

[0004] Based on this, the present invention designs a road anti-collision corrugated guardrail to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a road anti-collision corrugated guardrail.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A corrugated guardrail for road collision prevention, including posts; The lower end of the column is equipped with a stable support mechanism, the base plate is located on the upper side of the stable support mechanism, and the base plate is fixedly connected to the column by fasteners. The base plate is used to support the column on the ground foundation. The upper end of the column is equipped with an upper protective mechanism and a lower protective mechanism from top to bottom. The lower protective mechanism includes a vortex block, a support block and a corrugated plate. One end of the vortex block is fixedly connected to the side of the column by fasteners, and the other end of the vortex block is fixedly connected to the corrugated plate by fasteners. A support block is fixedly installed inside the vortex block.

[0007] Furthermore, the upper protective mechanism includes a plug, a top plate, a bent pipe, an arc-shaped mounting plate, and a crossbar. The plug is inserted into the inner top of the column and is fixedly connected to the column by fasteners. The top plate is fixedly installed on the upper end of the plug. One end of the bent pipe is fixedly connected to the top plate, and the other end of the bent pipe is fixedly installed with an arc-shaped mounting plate that accommodates the crossbar. The crossbar is fixedly connected to the arc-shaped mounting plate by fasteners.

[0008] Furthermore, the stabilizing support mechanism includes a cone head, a control component, and a barb fixing component. The cone head is fixedly installed at the lower end of the column for easy insertion into the ground foundation. The control component and the barb fixing component are installed on the inner side of the column and located above the cone head. The control component is used to drive the extension and retraction of the barb fixing component.

[0009] Furthermore, the control assembly includes a connecting plate, an adjusting screw, and an adjusting block. The connecting plate is fixedly connected to the inner wall of the column, and the connecting plate is threadedly connected to the adjusting screw via a threaded sleeve. An adjusting block is fixedly installed on the upper end of the adjusting screw.

[0010] Furthermore, the barb fixing assembly includes an arc-shaped insert plate, a connecting rod, and a connecting block. The arc-shaped insert plate is slidably connected to the side wall of the column for limiting. Multiple arc-shaped insert plates are arranged in a circumferential array and are evenly distributed at equal intervals.

[0013] Furthermore, the fasteners employ a bolt and nut fastening structure.

[0014] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, the column is supported on the ground foundation by the base plate and is stably connected to the ground foundation by the stable support mechanism, which reduces the possibility of the column being pulled out when it is impacted. In the event of a traffic accident, the accident vehicle comes into contact with the upper protective mechanism and collides with the corrugated plate of the lower protective mechanism after the upper protective mechanism is deformed. Thus, the upper and lower protective mechanisms work together to achieve the protective effect on the accident vehicle, and ensure that minor accidents only damage the upper protective mechanism, thereby reducing the maintenance cost of the guardrail. When a vehicle crashes into the corrugated plate, the plate expands under the impact, while the vortex blocks deform under pressure and absorb additional impact force through the buffer medium. The three work together to achieve a multi-faceted absorption effect on the impact force, forcing the out-of-control vehicle to slide along the corrugated plate, minimizing injury to occupants and damage to the vehicle.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0020] In some embodiments, please refer to the accompanying drawings. Figures 1-6A type of corrugated road safety barrier, including posts 1; The lower end of the column 1 is equipped with a stable support mechanism 5, the base plate 2 is located on the upper side of the stable support mechanism 5, and the base plate 2 is fixedly connected to the column 1 by fasteners. The base plate 2 is used to support the column on the ground. The upper end of the column 1 is equipped with an upper protective mechanism 3 and a lower protective mechanism 4 from top to bottom. The lower protective mechanism 4 includes a vortex block 41, a support block 42 and a corrugated plate 44. One end of the vortex block 41 is fixedly connected to the side of the column 1 by fasteners, and the other end of the vortex block 41 is fixedly connected to the corrugated plate 44 by fasteners. The support block 42 is fixedly installed inside the vortex block 41. A buffer medium 43 is filled between the vortex block 41 and the support block 42. In this embodiment, the buffer medium 43 is a rubber block. The outer end of the vortex block 41 extends in the opposite direction to the direction of traffic vehicle travel. When the traffic vehicle collides with the corrugated plate 44, the vortex block 41 deforms and is forced to unfold, thereby increasing the buffering and energy absorption effect.

[0021] In this utility model, the column 1 is supported on the ground foundation by the base plate 2 and is stably connected to the ground foundation by the stable support mechanism 5, which reduces the possibility of the column 1 being pulled out when it is impacted. In the event of a traffic accident, the accident vehicle comes into contact with the upper protective mechanism 3 and collides with the corrugated plate 44 of the lower protective mechanism 4 after the upper protective mechanism 3 deforms. Thus, the upper protective mechanism 3 and the lower protective mechanism 4 work together to achieve the protective effect on the accident vehicle, and ensure that minor accidents only damage the upper protective mechanism 3, thereby reducing the maintenance cost of the guardrail. When the accident vehicle hits the corrugated plate 44, the corrugated plate 44 is impacted and unfolds, while the vortex block 41 is compressed and deformed, and absorbs additional impact force through the buffer medium 43. The three work together to achieve a multiple absorption effect on the impact force, forcing the out-of-control vehicle to slide along the corrugated plate 44, minimizing injury to the occupants and damage to the vehicle.

[0022] The upper protective mechanism 3 includes a plug 31, a top plate 32, a bend 33, an arc-shaped mounting plate 34, and a crossbar 35. The plug 31 is inserted into the inner top of the column 1 and is fixedly connected to the column 1 by fasteners. The top plate 32 is fixedly installed on the upper end of the plug 31. One end of the bend 33 is fixedly connected to the top plate 32, and the other end of the bend 33 is fixedly installed with an arc-shaped mounting plate 34 that accommodates the crossbar 35. The crossbar 35 is fixedly connected to the arc-shaped mounting plate 34 by fasteners. In this invention, when the vehicle loses control in an accident, it will first collide with the crossbar 35, forcing the vehicle to slide along the smooth crossbar 35. If the impact force is large, the arc-shaped mounting plate 34 will be completely deformed, achieving the effect of absorbing the impact force and reducing injury to the occupants and damage to the vehicle.

[0023] The stabilizing support mechanism 5 includes a cone head 51, a control component, and a barb fixing component. The cone head 51 is fixedly installed at the lower end of the column 1 for easy insertion into the ground foundation. The control component and the barb fixing component are installed inside the column 1 and above the cone head 51. The control component is used to drive the extension and retraction of the barb fixing component. The control assembly includes a connecting plate 55, an adjusting screw 56, and an adjusting block 57. The connecting plate 55 is fixedly connected to the inner wall of the column 1. The connecting plate 55 is threadedly connected to the adjusting screw 56 through a threaded sleeve. The adjusting block 57 is fixedly installed on the upper end of the adjusting screw 56. The barb fixing assembly includes an arc-shaped insert plate 52, a connecting rod 53, and a connecting block 54. The arc-shaped insert plate 52 is slidably connected to the side wall of the column 1. Multiple arc-shaped insert plates 52 are arranged in a circumferential array and are evenly distributed at equal intervals. One end of the arc-shaped insert plate 52 is hinged to the connecting rod 53, and the other end of the connecting rod 53 is hinged to the connecting block 54. The lower end of the adjusting screw 56 is rotatably connected to the connecting block 54 through a bearing. In this utility model, the adjusting screw 56 is rotated by the adjusting block 57, which controls the vertical movement of the connecting block 54. When the connecting block 54 moves vertically downward, the arc-shaped insert plate 52 extends from the column 1 into the ground foundation through the connecting rod 53, forming a hook structure. This effectively increases the stability of the connection between the column 1 and the ground foundation and reduces the possibility of the column 1 being detached from the ground foundation due to a large impact. When it is necessary to retract the column 1, the connecting block 54 is moved upward and reset by rotating the adjusting screw 56, which allows the arc-shaped insert plate 52 to retract into the column 1, facilitating the detachment of the column 1 from the ground foundation.

[0024] In some embodiments, the fasteners employ a bolt and nut fastening structure.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
