Description

Technical Field

[0001] The utility model belongs to the technical field of road traffic safety, and particularly relates to a highway safety protection device. Background Technique

[0002] Highway safety protection devices are generally provided with guardrails on both sides of the highway to prevent pedestrians and livestock from crossing the highway, which have the functions of blocking and warning, thereby providing a safe field of vision in front for drivers when passing through the highway at high speed.

[0003] At present, the guardrails all have the ability to isolate animals and warn of the isolated highway, and the existing guardrails are mainly composed of vertical poles fixed on the roadbed and horizontal bars fixed perpendicular to the poles and parallel to the road surface. However, such guardrails have too single functions and have poor effect on reducing the speed of a vehicle in case of an accident during driving. Therefore, we provide a highway safety protection device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a highway safety protection device. When a vehicle driving on the road collides with the highway safety guardrail, the impact force first squeezes the cross plate, and then through the conduction of the cross plate and in cooperation with the auxiliary rod, it is pushed forward to the other side. At the same time, several elliptical rings squeeze each other. In this process, the speed of the vehicle can be effectively reduced. The speed is reduced on one side by hitting the external assembly block, and then the speed is reduced by secondary buffering through three elliptical rings. Thus, the speed reduction is improved compared with that of a single plate, and at the same time, the safety of the road is improved, solving the problem that the existing guardrails all have the ability to isolate animals and warn of the isolated highway, and the existing guardrails are mainly composed of vertical poles fixed on the roadbed and horizontal bars fixed perpendicular to the poles and parallel to the road surface. However, such guardrails have too single functions and have poor effect on reducing the speed of a vehicle in case of an accident during driving.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a highway safety protection device, including stabilizing columns. The number of the stabilizing columns is four, and every two of the four stabilizing columns are set as a group. The parts connected by the two stabilizing columns on the left are the same. The tops of the group of stabilizing columns on the left are fixedly connected with vertical plates by screws. Two fixing grooves are respectively opened on the fronts of the two vertical plates. Four threaded rods are respectively threadedly connected inside the four fixing grooves. Four cross plates are slidably connected to the outer surfaces of the four threaded rods. By opening fixing groove openings, the cross plates can be installed subsequently.

[0007] Further, every two of the four cross plates are set as a group. The parts connected by each group of cross plates are the same. Each group of two cross plates is symmetrically arranged. Springs are sleeved on the outer surfaces of the four threaded rods. Specifically, a vehicle driving on the road collides with the highway safety guardrail, and then the impact force generated first squeezes the cross plates, and then through the conduction of the cross plates and in cooperation with the auxiliary rods, it is pushed towards the other side. At the same time, several elliptical rings squeeze each other. During this process, the speed of the vehicle can be greatly reduced. The speed is reduced on one side by hitting the external assembly block, and then the speed is reduced by the three elliptical rings for secondary buffering, thus increasing the speed reduction compared with a single plate and improving the safety of the road at the same time.

[0008] Further, one side of each group of cross plates located above that is close to each other is fixedly connected to the spring. Two fixing blocks are arranged on the left side of the spring located on the left. Specifically, through the connection between the cross plate and the threaded rod and the interval of the spring, it is possible to prepare for installing the elliptical rings.

[0009] Further, one side of each group of cross plates located above that is close to each other is fixedly connected to the outer surface of the fixing block. Two assembling rods are fixedly connected to the left side of the fixing block. Through the setting of the assembly groove, the subsequent extended highway guardrail can be connected end to end, thus greatly extending the length of the guardrail and ensuring the safety of installation.

[0010] Further, two assembly blocks are arranged on the right side of the spring located on the right. One side of each group of cross plates located at the top that is close to each other is fixedly connected to the outer surface of the assembly block. By setting a bolt, specifically by connecting two guardrails end to end, the length of the highway guardrail can be extended. Thus, it can be extended and installed in sections with frequent accidents and sections with a large number of animals, thereby reducing the frequency of accidents. The fixing block and the assembling rod at the head are matched and installed with the assembly block, and then a bolt is inserted into the top of the assembly block to stably fix the assembling rod inside the assembly block, thus completing the assembly of two guardrails, thereby improving the convenience of assembly.

[0011] Further, two assembly grooves are opened on the right side of the assembly block, and a slot is opened on the top of the assembly block. A bolt is slidably connected to the inner wall of the slot. Specifically, through the setting of the assembling rod, elliptical rings can be installed on the assembling rod. Through the extrusion of the elliptical rings, the secondary speed reduction of the accident vehicle can be completed, thereby reducing the harm caused by the accident.

[0012] Further, four connecting grooves are provided on the front surfaces of a group of horizontal plates located above. An auxiliary rod is slidably connected to the inner wall of the connecting groove. Three elliptical rings are sleeved on the outer surface of the auxiliary rod. The interiors of the three elliptical rings are hollow. The sides of the three elliptical rings close to each other are in contact connection. Since the interiors of the elliptical rings are hollow, the elliptical rings can be deformed under force during collisions, thereby achieving the effect of speed reduction.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting the horizontal plates, specifically, when a vehicle driving on the road collides with the highway safety fence, the impact force first squeezes the horizontal plates, and then through the conduction of the horizontal plates and in cooperation with the auxiliary rods, it is pushed to the other side. At the same time, several elliptical rings are mutually squeezed. During this process, the speed of the vehicle can be significantly reduced. The speed is reduced on one side by hitting the external assembly block, and then secondary buffer speed reduction is carried out through the three elliptical rings. Thus, the speed reduction effect is improved compared with that of a single plate, and the safety of the road is also enhanced.

[0015] 2. By setting the pins, specifically, by connecting the two fences end to end, the length of the highway fence can be extended. Thus, it can be installed in sections with frequent accidents and sections with a large number of animals, thereby reducing the accident frequency. The fixed block and the assembly rod at the head are matched with the assembly block for installation adaptation, and then the assembly rod is stably fixed inside the assembly block by inserting a pin into the top of the assembly block, thus completing the assembly of the two fences. Thereby, the convenience of assembly is improved.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 As shown, the present utility model is a highway safety protection device, including four stabilizing columns 1. The four stabilizing columns 1 are set in groups of two. The parts connected by the two stabilizing columns 1 on the left are the same. The tops of the two stabilizing columns 1 on the left are fixedly connected to the vertical plates 11 by screws. Two fixing grooves are provided on the front surfaces of the two vertical plates 11. Four threaded rods 26 are threadedly connected inside the four fixing grooves, and four horizontal plates 2 are slidably connected to the outer surfaces of the four threaded rods 26.

[0028] The four horizontal plates 2 are set in groups of two. The parts connected by each group of horizontal plates 2 are the same. Each group of two horizontal plates 2 is symmetrically arranged. Springs 25 are sleeved on the outer surfaces of the four threaded rods 26. The present utility model reduces the speed of the vehicle to a greater extent by setting the horizontal plates 2. Specifically, when a vehicle traveling on the road collides with the highway safety fence, the impact force first squeezes the horizontal plates 2, and then through the conduction of the horizontal plates 2 and in cooperation with the auxiliary rods 21, it is pushed to the other side. At the same time, several oval rings 27 are mutually squeezed. During this process, the speed of the vehicle can be reduced to a greater extent. The speed is reduced on one side by hitting the external assembly block 22, and then the speed is further reduced by the three oval rings 27 for secondary buffering. Thus, the speed reduction is improved compared with that of a single plate, and at the same time, the safety of the road is improved.

[0029] On one side of a group of upper horizontal plates 2 close to each other, they are fixedly connected to the outer surface of a fixed block 24, and two assembly rods 23 are fixedly connected to the left side of the fixed block 24.

[0030] On the right side of a spring 25 on the right, there are two fitting blocks 22 arranged, and on one side of the upper horizontal plates 2 close to each other, they are fixedly connected to the outer surface of the fitting blocks 22.

[0031] Two fitting grooves 222 are opened on the right side of the fitting block 22, and a slot is opened on the top of the fitting block 22. A bolt 221 is slidably connected to the inner wall of the slot. Specifically, by connecting the two guardrails end to end, the length of the highway guardrail can be extended accordingly. Thus, it can be installed in an extended manner in sections with frequent accidents and sections with a large number of animals, thereby reducing the frequent accident rate. The fixed block 24 and the assembly rod 23 at the head are matched and installed adaptively with the fitting block 22, and then the bolt 221 is inserted into the top of the fitting block 22, so that the assembly rod 23 is stably fixed inside the fitting block 22, thus completing the assembly of the two guardrails, and the convenience of assembly can be improved accordingly.

[0032] On the front of a group of upper horizontal plates 2, four connecting grooves are opened, and auxiliary rods 21 are slidably connected to the inner walls of the connecting grooves. Three elliptical rings 27 are sleeved on the outer surface of the auxiliary rods 21. The interiors of the three elliptical rings 27 are hollow, and the sides of the three elliptical rings 27 close to each other are in contact connection.

[0033] A specific application of this embodiment is as follows: In actual use, first fix two stabilizing columns 1 on one side of the highway. Then, respectively fix the vertical plates 11 on the tops of the two stabilizing columns 1 through screws. Subsequently, pass the cross plate 2 through one cross plate 2 via the threaded rod 26, and at the same time insert the four auxiliary rods 21 through this cross plate 2. Then, slip a spring 25 over the periphery of the threaded rod 26, and then slip three elliptical rings 27 over the outer surfaces of the auxiliary rods 21. Finally, connect another cross plate 2 with the auxiliary rods 21 and the threaded rod 26, and then fix the spring 25 and the elliptical rings 27 to the cross plate 2 and the auxiliary rods 21 respectively through the device. Finally, fix the extended part of the threaded rod 26 to the two vertical plates 11 through nuts. Then, assemble the bottom cross plate 2 until this set of assembly is completed. Finally, assemble on the left and right sides of the stabilizing column 1 respectively. Similarly, the device is combined with the assembly block 22 through the cooperation of the fixing block 24 and the assembly rod 23. Finally, install a pin 221 on the top of the assembly block 22 to fix the assembly rod 23 to the assembly block 22. By connecting end to end, it can be extended and assembled on the road. When a moving vehicle collides, the vehicle first collides with the two outer cross plates 2, and then the huge impact force brings presses the cross plate 2 inward. Then, the outer cross plate 2 reduces the vehicle speed by squeezing the three elliptical rings 27. Thus, compared with the traditional single plate, it can better protect the vehicle from decelerating and reduce the disaster level caused by the collision.
