Description

Technical Field

[0001] This utility model relates to the field of highway guardrail technology, and more specifically, to a highway guardrail. Background Technology

[0002] Highways are dedicated roads for high-speed vehicle travel. To ensure safe passage, highways are generally equipped with guardrails on both sides to effectively prevent pedestrians and animals from entering the lanes.

[0003] However, the following problems still exist in the installation and use of the isolation fence:

[0004] 1. Current fencing construction relies heavily on bolts to secure the protective netting to the poles. This process requires frequent bolt tightening, which is extremely time-consuming and labor-intensive. Furthermore, exposed bolts are susceptible to corrosion and rust from rainwater and salt spray, leading to decreased connection strength, loosening, or even breakage and detachment, posing safety hazards and requiring frequent maintenance.

[0005] 2. Existing guardrails primarily serve as physical barriers, with a rigid structure and no energy-absorbing design. When a vehicle loses control and crashes into the guardrail, the barrier may break instantly or subject the vehicle to a massive impact, failing to effectively cushion and decelerate the impact. This lack of secondary energy-absorbing protection significantly increases the risk of injury to occupants in accidents.

[0006] 3. Guardrail poles are generally fixed by deep-buried concrete foundations. Once a pole is damaged by an impact, repairs require the use of heavy tools to break and excavate the concrete block covering the lower end of the pole, remove the debris, and then re-tie the reinforcing bars, erect formwork, pour new concrete, and cure it. Repairs are extremely inconvenient.

[0007] Therefore, in order to address the above problems, there is an urgent need to develop a highway guardrail. Utility Model Content

[0017] (III) Beneficial Effects

[0019] 1. This utility model uses the cooperation of the limiting block and the wedge block in the fixing block to quickly install the protective net between two installation rods, which improves the construction efficiency of the isolation fence installation.

[0020] 2. This utility model uses shear pins to absorb the impact on the mounting rod, thereby buffering the car that runs off the highway and improving the safety of the vehicle and its occupants.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0033] Please see Figures 1-7 A highway guardrail includes a mounting rod 1, a sliding sleeve 2 slidably connected to the upper part of the mounting rod 1, two fixing blocks 3 fixed to both the sliding sleeve 2 and the mounting rod 1, the fixing blocks 3 having grooves, wedge blocks 4 slidably connected to the grooves of the fixing blocks 3, fixing posts 5 fixed to the upper side of the wedge blocks 4, magnets 6 fixed to the fixing posts 5, a protective net 7 provided on one side of the mounting rod 1, a limit block 8 fixed to the protective net 7, a blind hole provided on the upper side of the limit block 8, the wedge blocks 4 and the blind holes of the adjacent limit blocks 8 being limited and matched, the mounting rod 1 having a connecting structure; an inclined surface provided on one side of the limit block 8; a fixing ring 9 fixed to the upper part of the mounting rod 1, a spring 10 fixed between the fixing ring 9 and the adjacent sliding sleeve 2.

[0034] Specifically, in this embodiment, when installing the protective net 7, the worker lifts the protective net 7 and moves it backward, while adjusting the position of the sliding sleeve 2. When the sliding sleeve 2 moves downward, the spring 10 is compressed. By adjusting the position of the sliding sleeve 2, the four limiting blocks 8 are simultaneously inserted into the grooves of the adjacent fixing blocks 3. The limiting blocks 8 move into the grooves of the adjacent fixing blocks 3, and the inclined surface of the limiting blocks 8 presses against the adjacent wedge blocks 4. The wedge blocks 4 drive the fixing posts 5 and magnets 6 on them to move upward. When the wedge blocks 4 move to the blind hole of the limiting blocks 8, they move downward under the action of gravity, so that the wedge blocks 4 are inserted into the blind hole of the adjacent limiting blocks 8, thereby installing the protective net 7 between the two mounting rods 1. When replacing the protective net 7, it is only necessary to place the magnetic block on the upper side of the fixing block 3. The magnetic block attracts the magnet 6, causing the wedge blocks 4 to move out of the blind holes of the adjacent limiting blocks 8. Then the protective net 7 can be removed from the two mounting rods 1.

[0035] Please see Figures 5-7 The connecting structure includes a mounting base 11 located below the mounting rod 1. The mounting base 11 is rotatably connected to a pin 12, and the pin 12 is rotatably connected to a connecting block 13. The connecting block 13 is fixedly connected to a shearing block 14, which has a through hole. The mounting base 11 is inserted with a pin 15, which is located in the through hole of the shearing block 14. The connecting block 13 is fixedly connected to a limiting sleeve 16, which has a limiting groove. The mounting rod 1 is fixedly connected to a connector 17, which is fixedly connected to two mounting blocks 18. The mounting blocks 18 are limited and engaged with the limiting groove of the limiting sleeve 16.

[0036] Specifically, in this embodiment, the mounting base 11 is cast onto the ground with cement. Then, the connector 17 at the lower end of the mounting rod 1 is inserted into the limiting groove of the limiting sleeve 16. Then, the mounting rod 1 is rotated, and the connector 17 drives the two mounting blocks 18 to rotate 90° within the limiting groove of the limiting sleeve 16 (see reference). Figure 2 ).

[0037] When the protective net 7 and the mounting rod 1 are impacted, the mounting rod 1 drives the connecting block 13 to rotate along the pin 12 through the connector 17. The shearing block 14 shears the pin 15, thereby absorbing the impact on the mounting rod 1 and buffering the impacting car. When reset is required, a new pin 15 is simply inserted into the through hole of the shearing block 14. When the mounting rod 1 is damaged, the mounting rod 1 can be rotated directly to separate the connector 17 and the limiting sleeve 16, and a new mounting rod 1 can be replaced.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
