Description

Technical Field

[0001] The utility model relates to the technical field of highways, in particular to an anti-collision type highway construction guardrail. Background Art

[0002] With the development of the transportation industry, highway construction and maintenance has become a common situation. During the highway construction and maintenance process, other passing vehicles need to slow down and detour. The main function of using highway construction guardrails is to prevent vehicle accidents. During use, the existing highway construction guardrails slow down the impact of the car by their own body, which cannot prompt the car to stop fully. Once the impact is too great, it directly endangers the safety of the construction workers. Moreover, once the traditional guardrail is damaged, it needs to be replaced as a whole, which increases the cost of use and has poor practicality. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-collision type highway construction guardrail, which is used to overcome the above-mentioned defects in the prior art.

[0010] In some embodiments, screws are rotatably provided on the inner walls on the left and right sides of the main box body and penetrate the main box body, and the screws abut against the replacement rack to fix the replacement rack.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] 1. The utility model starts to start through the valve, so that a large amount of gas is extracted from the inflation pump, and then the gas flows into the valve from the air guide tube, thereby driving the airbag to begin to expand, and then the guide shell begins to pop out toward the collision point, so that at this time, a part of the impact caused by the collision is offset, thereby achieving preliminary anti-collision. At the same time, at this time, the guide shell drives the guide frame to move toward the rear side, and at this time, the evenly distributed telescopic rods and shock-absorbing springs begin to shrink, and then all the remaining impact force is offset, thereby achieving secondary offset of the impact force, thereby achieving double anti-collision, further fully ensuring that the vehicle can stop and ensuring the safety of highway construction.

[0013] 2. The utility model realizes the disassembly of the replacement frame, the guide frame, the guide housing and other parts by rotating the left-right symmetrical screws to drive the screws to move outward, so that the user holds the handle and lifts the replacement frame upward, thereby facilitating timely maintenance and replacement of some parts, thus changing the traditional problem of needing to replace the entire frame once it is impacted, further reducing the cost of use, thereby simplifying the cumbersome disassembly, and increasing the practicality of the guardrail.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 6 , which is the first embodiment of the utility model, and this embodiment provides an embodiment of an anti-collision highway construction guardrail, including a main box body 11, wherein the main box body 11 is provided with a sliding cavity 25 connected to the outside, wherein a replacement frame 12 is provided in the sliding cavity 25 and is inserted into the main box body 11, wherein a plurality of groups of telescopic rods 24 that are evenly distributed and can be telescopically moved are fixedly provided on the front end surface of the replacement frame 12, wherein the telescopic rods 24 play a role of limiting, wherein a guide frame 17 is fixedly provided on the other end of the telescopic rod 24, wherein a shock-absorbing spring 23 that can be telescopically moved is fixedly provided on the front end surface of the replacement frame 12 and corresponds one by one to the outside of the telescopic rod 24, thereby achieving the effects of reducing impact and preventing collision, wherein a guide frame 17 is fixedly provided on the other end of the telescopic rod 24, wherein an inflation cavity 21 is provided in the guide frame 17, wherein an air bag 20 that can be rapidly expanded is provided in the inflation cavity 21, wherein the air bag 20 plays a role of preventing collision.

[0026] A handle 14 is fixedly disposed on the rear end surface of the replacement frame 12 , and an air pump 13 is fixedly disposed inside the replacement frame 12 , and the air pump 13 serves to store gas.

[0027] The upper end surface of the airbag 20 is fixedly connected to the upper wall of the inflation chamber 21 , and the front end surface of the airbag 20 is fixedly provided with a guide shell 18 .

[0028] A collision sensor 19 is fixedly disposed on the front end surface of the guide housing 18 , and the collision sensor 19 serves to detect collision.

[0029] An air guide tube 15 is fixedly disposed on the upper end surface of the air pump 13 , and the other end of the air guide tube 15 is fixedly connected to the guide frame 17 .

[0030] A valve 16 is fixedly disposed inside the airbag 20 , and the valve 16 starts to control the inflow and outflow of gas.

[0031] Screws 22 are rotatably provided on the inner walls of the left and right sides of the main box body 11 and penetrate the main box body 11 . The screws 22 abut against the replacement frame 12 , thereby fixing the replacement frame 12 .

[0032] Specific workflow:

[0033] At this time, the user places the main box 11 on the periphery of the construction and fixes it, and the guide shell 18 faces outward. At this moment, when the vehicle collides with the guide shell 18, the collision sensor 19 begins to detect the collision, and the valve 16 starts to start, so that a large amount of gas is extracted from the inflation pump 13, and then the gas flows into the valve 16 from the air guide pipe 15, thereby driving the airbag 20 to begin to expand, and then the guide shell 18 begins to pop out toward the collision point, thereby achieving a part of the impact caused by the collision, thereby achieving preliminary anti-collision. At the same time, the guide shell 18 drives the guide frame 17 to move toward the rear side, and the evenly distributed telescopic rods 24 and the shock-absorbing springs 23 begin to shrink, thereby completely offsetting the remaining impact force, thereby achieving secondary offset of the impact force, thereby achieving double anti-collision, further fully ensuring that the vehicle can stop and ensuring the safety of highway construction.

[0034] Due to the impact force of the collision belt, the guide shell 18 and the guide frame 17 will be partially deformed. At this time, it is necessary to rotate the left-right symmetrical screws 22 to drive the screws 22 to move outward, so that the user holds the handle 14 and lifts the replacement frame 12 upward, thereby realizing the disassembly of the replacement frame 12, the guide frame 17, the guide shell 18 and other parts, which is convenient for timely maintenance and replacement of some parts, thereby changing the traditional problem of needing to replace the entire part once it is impacted, further reducing the cost of use, thereby simplifying the cumbersome disassembly, and increasing the practicality of the guardrail.
