Description

Technical Field

[0001] This utility model relates to the field of highway infrastructure technology, specifically a collision-resistant highway guardrail. Background Technology

[0002] High-grade highways, such as national and provincial highways, typically isolate the section under repair during maintenance, while allowing vehicles to pass through the unisolated section, thus minimizing the economic impact of traffic disruption. Current isolation facilities include metal guardrails, traffic cones, and reflective signs, which are sufficient for normal situations. However, in rainy or snowy weather, or on long slopes, if a vehicle collides with a vehicle, cones and similar devices become ineffective, metal guardrails collapse upon impact, and even after being knocked away, the wheels may still slip and brake insufficiently, continuing forward, posing a safety risk to road maintenance personnel. Therefore, the applicant's technical personnel have provided a collision-resistant highway isolation guide plate to solve the aforementioned technical problems. Utility Model Content

[0003] The purpose of this utility model is to provide a highway guardrail for collision prevention.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A collision-resistant highway guardrail includes two bases. The upper surfaces of the bases have a first groove and a second groove. A first movable block is slidably connected to the inner wall of the first groove. A first spring is provided in the first groove, with one end fixed to the first movable block and the other end fixed to the inner wall of the first groove. A second movable block is slidably connected to the inner wall of the second groove. A second spring is fixedly connected to the side wall of the second movable block and to the inner wall of the second groove. A vertical rod is fixedly connected to the upper surface of the first movable block. A diagonal rod is fixedly connected to the back of the vertical rod, with the bottom end of the diagonal rod fixedly connected to the upper surface of the second movable block. A support plate is fixedly connected to the front of the vertical rod. Limiting grooves are provided on the left and right sides of the support plate. A protective plate body is provided between adjacent support plates, with both ends of the protective plate body movably inserted into the limiting grooves.

[0006] A mounting plate is provided below the base, and the upper surface of the mounting plate is fixedly connected to the bottom surface of the base.

[0007] A reinforcing block is fixedly connected between the base and the mounting plate. The bottom surface of the reinforcing block is fixedly connected to the upper surface of the mounting plate, and the side surface of the reinforcing block is fixedly connected to the side surface of the base.

[0008] The top of the pole is equipped with a reflective warning light, and the bottom of the reflective warning light is detachably connected to the top of the pole.

[0009] A set of connecting blocks is fixedly connected to both the left and right sides of the upright, and the front of each connecting block is fixedly connected to the back of the support plate.

[0010] The inner sidewalls of the first groove are all fixedly connected with buffer pads, and the exposed surface of the buffer pads is in contact with the side of the first moving block.

[0011] As a further improvement of this utility model: a slogan sign is provided on the front of the support plate, the back of the slogan sign is bonded to the surface of the support plate, and the slogan sign is printed with reflective material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by using the cooperation of the first groove, the first spring and the first moving block to fix the main body of the guard plate, the main body of the guard plate can move backward after being impacted, thus absorbing the force and buffering; by using the cooperation of the second groove, the second spring, the second moving block and the diagonal bar, the upright can be reinforced, thereby further enhancing the impact resistance of the highway guard plate; and by using the support plate and the limiting groove, the installation of the main body of the guard plate can be facilitated.

[0018] A collision-resistant highway guardrail includes two bases 1. The upper surface of each base 1 has a first groove 12 and a second groove 14. A first movable block 11 is slidably connected to the inner wall of the first groove 12. A first spring 13 is provided in the first groove 12, with one end fixed to the first movable block 11 and the other end fixed to the inner wall of the first groove 12. A second movable block 15 is slidably connected to the inner wall of the second groove 14. A second spring 9 is fixedly connected to the side wall of the second movable block 15 and to the inner wall of the second groove 14. A vertical rod 17 is fixedly connected to the upper surface of the first movable block 11. A diagonal rod 8 is fixedly connected to the back of the vertical rod 17, and the bottom end of the diagonal rod 8 is fixedly connected to the upper surface of the second movable block 15. A support plate 18 is fixedly connected to the front of the vertical rod 17. Limiting grooves 16 are provided on the left and right sides of the support plate 18. A protective plate body 3 is provided between adjacent support plates 18, with both ends of the protective plate body 3 movably inserted into the limiting grooves 16.

[0019] Each base 1 has a mounting plate 2 underneath, and the upper surface of each mounting plate 2 is fixedly connected to the bottom surface of the base 1. The mounting plate 2 facilitates the installation and fixation of the base 1 by the staff. Two reinforcing blocks 5 are fixedly connected to the left and right sides of each base 1. The bottom surface of each reinforcing block 5 is fixedly connected to the upper surface of the mounting plate 2. The reinforcing blocks 5 make the connection between the base 1 and the mounting plate 2 more secure. Each upright 17 has a reflective warning light 6 at the top. The bottom surface of each reflective warning light 6 is detachably connected to the top of the upright 17 (such as by a buckle or threaded connection). The warning light 6 can serve as a reminder to passing vehicles.

[0020] Each upright 17 has a set of connecting blocks 7 fixedly connected to its left and right sides. The front of each connecting block 7 is fixedly connected to the back of the support plate 18. The connecting blocks 7 can reinforce the support plate 18 and the upright 17. Each first groove 12 has a buffer pad 10 fixedly connected to its inner side wall. The back of each buffer pad 10 is in contact with the front of the first moving block 11. The buffer pad 10 can protect the inside of the first groove 12 and prevent the first moving block 11 from impacting it and causing wear. Each support plate 18 has a signboard 4 on its front. The back of each signboard 4 is glued to the front of the support plate 18. The signboard 4 is reflective and can be used to post safety slogans.

[0021] The working principle of this utility model is as follows: The mounting plate 2 is installed in its designated position by bolts through screw holes drilled in the ground. When the guardrail body 3 is struck by a vehicle, the impact force pushes the upright 17 and diagonal brace 8, causing the first moving block 11 and the second moving block 15 to move backward simultaneously. The impact is absorbed by the first spring 13 and the second spring 9, thus reducing the damage to the vehicle and the guardrail. After the bolts are removed, the screw holes are filled with asphalt to prevent rainwater from entering.
