Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge protection, in particular to a road and bridge protection device used in bridge engineering. Background Art

[0002] Roads and bridges are generally composed of several parts, such as roadbed, pavement, bridges, tunnel engineering and traffic engineering facilities. Roads and bridges are infrastructure for various trackless vehicles and pedestrians to pass through. Among them, roads are divided into highways, urban roads, rural roads, factory and mine roads, forestry roads, test roads, competition roads, automobile test roads, workshop passages and school roads according to their usage characteristics. In order to ensure the safety of vehicles and pedestrians on the road, corresponding protective devices are often installed on the road.

[0003] However, the road and bridge protection devices currently in use mainly consist of two sets of barrier bars to block the impact of cars, which cannot effectively alleviate the impact force, and have relatively single functions. They cannot effectively absorb the noise generated during the driving of cars, causing greater noise pollution.

[0004] In view of this, research and improvements are conducted on the existing problems, and a road bridge protection device for bridge engineering is provided, which has a reasonable structural design, integrates noise absorption, convenient installation, and impact resistance, reduces manpower and material resources, and greatly improves work efficiency. The purpose is to solve problems and improve practical value through this technology. Utility Model Content

[0026] Reference Figure 1-3The utility model provides an embodiment: a road bridge protection device for bridge engineering, comprising a base 1, a vertical pole 2 is movably connected to the top of the base 1, and a fixing piece 3 is movably connected to the outer wall of the vertical pole 2 to prevent the vertical pole 2 from falling off with the impact force after collision, a blocking rod 4 is movably connected to one side of the vertical pole 2, and a protective plate 5 is fixedly connected to one side of the blocking rod 4 to play a bottom supporting role to prevent the reinforcing plate 6 from being unable to withstand the impact force and being damaged and unable to block the car, and the outer wall of the protective plate 5 is fixedly connected to the reinforcing plate 6 to play a certain role in buffering impact force and reducing the impact force directly colliding with the steel blocking object, a fixing plate 7 is fixedly connected to the outer wall of the blocking rod 4, a first fixing hole 8 is arranged on the outer wall of the fixing plate 7, a second fixing hole 9 is arranged on the outer wall of the fixing piece 3, a sound absorbing plate 10 is fixedly connected to the inside of the protective plate 5 to absorb a certain amount of noise, a first docking hole 11 is arranged on one side of the vertical pole 2, a third fixing hole 12 is arranged on one side of the first docking hole 11, a docking block 13 is fixedly connected to the bottom of the vertical pole 2, and a second docking hole 14 is arranged on the top of the base 1.

[0027] Specifically, the fixing member 3 is L-shaped in appearance, and every two fixing members 3 are used to fix a group of upright poles 2, so that the upright poles 2 are more stable and the possibility of falling off from the base 1 is reduced.

[0028] Specifically, docking blocks 13 are provided at the bottom of the upright pole 2 and on both sides of the blocking pole 4. The first docking hole 11 is consistent in size with the second docking hole 14. The inner diameter of the first docking hole 11 matches the outer diameter of the docking block 13, so that docking can be performed quickly and the time consumed in installation can be reduced.

[0029] Specifically, the upper and lower sides of the blocking rod 4 are fixedly connected with fixing plates 7, and the first fixing holes 8 on the outer wall of the fixing plates 7 are aligned with the second docking holes 14 on the outer wall of the upright pole 2, thereby reducing the possibility of the blocking rod 4 falling off from the upright pole 2.

[0030] Specifically, the reinforcing plate 6 is composed of a polymer material, and the reinforcing plate 6 is in a mesh structure on the outer wall of the protective plate 5. The protective plate 5 is composed of a steel material. The sound absorbing plate 10 is composed of a mineral wool material, which can buffer the impact force and prevent the traditional protective device from causing the car to directly collide with the steel protective device, while absorbing a certain amount of noise and reducing noise pollution.

[0031] Working principle: When a car collides with the protective device while driving, the reinforcing plate 6 is impacted first. Because it is made of polymer, it has excellent impact resistance and can disperse part of the impact force of the car collision to reduce damage to the human body. When the reinforcing plate 6 cannot withstand the impact, the car is blocked by the protective plate 5 made of steel to prevent the car from running off the road or bridge deck. When the car is driving normally, it is easy to generate noise. The noise generated can absorb a certain amount of noise to prevent the noise from being transmitted and reduce the impact on people living on the roadside.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
