Detailed implementation mode

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. The implementation modes of the present utility model include but are not limited to the following embodiments.

[0026] First embodiment:

[0027] As Figures 1-3As shown in the figure, the anti-collision guardrail for transportation roads provided by the present utility model includes: a road anti-collision guardrail mechanism 100 and an anti-collision buffer zone component 200. The anti-collision buffer zone component 200 includes an anti-collision plate 206, which is made of durable metal materials. These materials have good impact resistance performance, can effectively absorb and disperse the impact force, and protect the rear structure from damage. One end of the anti-collision plate 206 is connected and fixed to a buffer pad 202 by screws. One end of the buffer pad 202 is connected and fixed to a buffer plate 201 by screws. One end of the buffer plate 201 is connected and fixed to several first connection blocks 209 by screws. A buffer spring 210 is fixedly installed at one end of the several first connection blocks 209. A second connection block 211 is installed at one end of the buffer spring 210. One end of the second connection block 211 is connected by screws to both side ends of the guardrail pole 208. Sliding blocks 107 are connected and fixed to both side ends of the guardrail pole 208 by welding. Both side ends of the anti-collision plate 206 are connected by screws to a first connection panel 101 and a second connection panel 102. The first connection panel 101 and the second connection panel 102 are connected to a first installation fixing rod 104 and a second installation fixing rod 110 by welding. In actual use, the anti-collision plate 206 is made of durable metal materials, has good impact resistance performance, can effectively absorb and disperse the impact force, and protect the rear structure from damage. The buffer pad 202 is usually made of materials such as cowhide, polyurethane, or rubber, and can buffer the collision impact force of other vehicles. The buffer plate 201 is usually made of materials such as corrugated fiberboard, EPE, or expanded polyethylene to reduce damage to the guardrail pole 208 caused by the impact of other vehicles. When other vehicles collide with the anti-collision plate 206 during driving to absorb the impact force, it is further transmitted to the buffer pad 202 and the buffer plate 201, and more impact force can be dispersed. Then, the buffer spring 210 will expand and contract to buffer the impact force of the vehicle, which can reduce the damage to the guardrail pole 208 caused by the impact force of other vehicles and decompose and disperse it, and avoid additional risks caused by the scattered fragments of the guardrail pole 208 to other vehicles or pedestrians.

[0028] In this embodiment, by using the anti-collision buffer zone component 200, the anti-collision plate 206 serves as the first line of defense to absorb and disperse the impact force of other vehicles, reducing the degree of damage to the rear structure. The buffer pad 202 can reduce the damage to the vehicle and the anti-collision plate 206 caused by the impact, and at the same time reduce the possibility of the impact force transmitted by the impact to the rear structure, reducing the damage to the guardrail pole 208 caused by the impact of other vehicles. The buffer plate 201 can reduce the direct impact on the guardrail pole 208 by dispersing the impact force, helping to reduce the damage to the guardrail pole 208 caused by the impact force of other vehicles, and avoiding additional risks caused by the scattered fragments of the guardrail pole 208 to other vehicles or pedestrians.

[0029] Second Embodiment:

[0030] As Figures 3-5 shown, the sliding block 107 of the guardrail 208 is slidably connected to the first mounting and fixing rod 104 and the second mounting and fixing rod 110. Moving grooves 105 and gap slots 106 are provided inside the first mounting and fixing rod 104 and the second mounting and fixing rod 110. One end of the sliding block 107 of the guardrail 208 is connected and fixed to the fixing bolt 108 by welding. The fixing bolt 108 passes through the inside of the gap slot 106. The fixing bolt 108 is connected with a fixing square block 109 through penetration. In actual use, when the operator performs maintenance and replacement of the guardrail 208, the sliding block 107 of the guardrail 208 is inserted into the moving grooves 105 of the first mounting and fixing rod 104 and the second mounting and fixing rod 110, and can be adjusted and moved. Further, the fixing bolt 108 can move inside the gap slot 106. Then, the fixing square block 109 passes through the fixing bolt 108, and the operator fixes and tightens the fixing square block 109, and fixes the guardrail 208, which can facilitate the operator to maintain and replace the guardrail 208 and can reduce the overly cumbersome disassembly and installation of the screws for the guardrail 208.

[0031] In this embodiment, by using the fixing bolt 108, the fixing square block 109, the moving groove 105 and the sliding block 107, by inserting the sliding block 107 of the guardrail 208 into the moving groove 105 and fixing it through the fixing bolt 108 and the fixing square block 109, the operator can easily maintain and replace the guardrail 208. The use of the fixing square block 109 makes the fixing process simpler, without the need for a large number of screws and tools. The simplified operation steps and convenient fixing method can improve the efficiency of maintenance and replacement.

[0032] Third Embodiment:

[0033] As Figure 3 、 Figures 5-6 shown, the upper ends of the first mounting and fixing rod 104 and the second mounting and fixing rod 110 are connected and fixed to the fixing top block 103 by screws. The lower ends of the first mounting and fixing rod 104 and the second mounting and fixing rod 110 are connected and fixed to the moving block 303 by welding. The moving block 303 is slidably connected inside the mounting base 301. A sliding groove 305 is provided inside the mounting base 301. In actual use, the moving block 303 can move in the sliding groove 305 inside the mounting base 301, and the moving block 303 is tightened and fixed by the threaded bolt 304.

[0034] Fourth Embodiment:

[0035] As Figures 5-6 shown, the moving block 303 is connected to the upper end of the mounting base 301 by the threaded bolt 304.

[0036] Fifth Embodiment:

[0037] As Figure 6 shown, a partition 302 is installed at the lower end of the mounting base 301. The partition 302 is connected to the lower end of the mounting base 301 through a connecting bolt 306. Contacting the ground through the partition 302 can prevent the mounting base 301 from being worn over a long period of time and other situations from occurring.

[0038] In this embodiment, by utilizing the partition 302, the partition 302 serves as an additional layer between the mounting base 301 and the ground, which can effectively prevent the base from directly contacting the ground, thereby reducing wear caused by friction and impact. The partition 302 increases the contact area between the base and the ground, thereby improving the structural stability. On uneven ground, the partition 302 can provide more uniform support to prevent the base from tilting or moving.

[0039] During use, first, the moving block 303 can move in the sliding groove 305 inside the mounting base 301, and the moving block 303 is tightened and fixed through the threaded bolt 304. The sliding block 107 of the guardrail 208 is inserted into the moving grooves 105 of the first mounting and fixing rod 104 and the second mounting and fixing rod 110 and can be adjusted and moved. Further, the fixing bolt 108 can move inside the gap slot 106. Then, the fixing square 109 passes through the fixing bolt 108, and the operator fixes and tightens the fixing square 109 to fix the guardrail 208. After that, when other vehicles collide with the anti-collision plate 206 during driving, the impact force is absorbed and further transmitted to the buffer pad 202 and the buffer plate 201, which can disperse more impact force. Then, the buffer spring 210 will expand and contract to buffer the impact force of the vehicle, which can reduce the damage caused by the impact force of other vehicles to the guardrail 208 and decompose and disperse it, avoiding additional risks caused by the scattered fragments of the guardrail 208 to other vehicles or pedestrians.

[0040] The above embodiments are only one of the preferred embodiments of the present utility model and should not be used to limit the protection scope of the present utility model. Any meaningless changes or polish made on the main design concept and spirit of the present utility model, as long as the technical problems solved are still the same as those of the present utility model, should be included in the protection scope of the present utility model.
