Description

Technical Field

[0001] This utility model relates to the field of anti-collision device technology, specifically an anti-collision device for highway bridges. Background Technology

[0002] With the development of technology, cars have become an essential means of transportation for people. However, cars can also easily cause safety problems during driving. When the speed is too fast or when the driver is fatigued, the car is likely to run off the sides of the road or bridge, causing serious damage to people's lives and property. Therefore, people often install crash barriers on both sides of roads or bridges.

[0003] For example, Chinese patent CN208121638U discloses a collision avoidance device for highway bridges, which includes several fixed posts fixed to the ground, a mounting plate slidably connected to the fixed posts in the horizontal direction, several bent connecting ears mounted on the mounting plate, a buffer pad clamped between the connecting ears and the mounting plate, a bearing seat mounted in front of the connecting ears, and a buffer roller rotatably mounted between two bearing seats in the vertical direction. The buffer roller includes a rotating shaft made of metal material and a rubber sleeve fitted over the rotating shaft. When a vehicle hits the device, the buffer roller rotates, guiding the vehicle to move in the direction of travel of the highway bridge, gradually converting the impact force into the upward motion of the vehicle, thus mitigating the impact and ensuring the safety of people's property and lives.

[0004] Although the aforementioned patent gradually transforms the impact force into the upward motion of the vehicle, thus mitigating the impact and ensuring greater safety for people's property and lives, the patent uses springs to cushion the impact of the vehicle. However, the springs have a large rebound force and their cushioning performance is generally poor, which reduces their practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a collision avoidance device for highway bridges, which has advantages such as improving the buffering performance of collision avoidance devices for highway bridges. It solves the problem that when using springs to buffer vehicle impacts, the springs have a large rebound force and the buffering performance is generally poor, thus reducing practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision avoidance device for highway bridges, including a ground surface, a supporting guardrail frame is provided on the ground surface, and a buffer mechanism is provided on the right side of the supporting guardrail frame;

[0007] The buffer mechanism includes a fixed plate, at least two buffer cylinders, at least two buffer fixing blocks, at least two buffer sliding rods, at least two mounting plates, a support plate, and connecting components. The fixed plate is fixed to the right side of the supporting guardrail frame by bolts. At least two buffer cylinders are arranged on the upper and lower sides of the right side of the fixed plate.

The right side of at least two buffer sliding rods is fixedly connected to the left side of at least two mounting plates.

[0008] By adopting this technical solution, the buffering performance of anti-collision devices for highway bridges can be improved.

[0009] Furthermore, the buffer sliding rod is fitted with a gap in the buffer cylinder, and the buffer sliding rod moves linearly left and right inside the buffer cylinder.

[0010] By adopting this technical solution, the buffer sliding rod can move stably inside the buffer cylinder.

[0011] Furthermore, the connecting assembly includes at least two connecting pieces, at least two rotating rods, and at least two anti-collision cylinders. The at least two connecting pieces are all disposed on the upper and lower sides of the right side of the support plate. The at least two rotating rods are all rotatably connected to the opposite side of the upper and lower connecting pieces via bearings. The at least two anti-collision cylinders are all rotatably connected to the outside of the at least two rotating rods via bearings.

[0012] By adopting this technical solution, the connecting components can guide the vehicle to move in the direction of travel on the highway bridge.

[0013] Furthermore, at least two of the aforementioned anti-collision cylinders are each provided with a buffer cylinder on their outer side, and the buffer cylinder is a rubber cylinder.

[0014] By adopting this technical solution, the impact force can be buffered through the buffer cylinder.

[0015] Furthermore, at least two of the buffer cylinders are evenly distributed on the upper and lower sides of the right side of the fixed plate.

[0016] By adopting this technical solution, the stability of the buffer cylinder during fixation is improved.

[0017] Furthermore, at least two of the connecting pieces are evenly distributed on the upper and lower sides of the right side of the support plate.

[0018] By adopting this technical solution, at least two anti-collision cylinders can be evenly arranged on the right side of the support plate.

[0019] Furthermore, the gap between the buffer cylinder and the anti-collision cylinder is matched.

[0020] By adopting this technical solution, the stability of the buffer cylinder fixed to the outside of the anti-collision cylinder is improved.

[0021] Furthermore, the buffer fixing blocks, numbering no less than two, are all buffer rubber blocks. The top and bottom walls of the inner cavity of the buffer cylinder are provided with limiting grooves. Sliding blocks are slidably connected inside the upper and lower limiting grooves. The opposite sides of the upper and lower sliding blocks are fixedly connected to the upper and lower sides of the buffer sliding rod.

[0022] By adopting this technical solution, the buffering performance of the anti-collision device can be improved by using no fewer than two buffer fixing blocks.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The anti-collision device for this highway bridge has at least two anti-collision cylinders, each with a buffer rubber cylinder on its outer side. At the same time, at least two buffer fixing blocks on the upper and lower sides can be compressed and absorb energy, which can buffer and absorb the energy of vehicles. At the same time, at least two anti-collision cylinders can rotate to guide vehicles to move in the direction of travel on the highway bridge, reducing the impact force and making people's property and life safer. By turning the bolts on the right side of the fixing plate, the fixing plate can be removed from the right side of the supporting guardrail frame, which facilitates the maintenance of the buffer structure on the right side of the fixing plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 This embodiment of a highway bridge anti-collision device includes a ground 1, a supporting guardrail 2 is provided on the ground 1, and a buffer mechanism 3 is provided on the right side of the supporting guardrail 2. The buffer mechanism 3 can improve the buffering performance of the highway bridge anti-collision device.

[0031] Please see Figures 2 to 3 In order to improve the buffering performance of the anti-collision device for highway bridges, the buffer mechanism 3 in this embodiment includes a fixed plate 31, at least two buffer cylinders 32, at least two buffer fixing blocks 33, at least two buffer sliding rods 34, at least two mounting plates 35, a support plate 36, and a connecting assembly. The fixed plate 31 is fixed to the right side of the support guardrail frame 2 by bolts, and at least two buffer cylinders 32 are all arranged on the upper and lower sides of the right side of the fixed plate 31.

[0032] In this embodiment, support guardrails 2 and buffer mechanisms 3 can be installed on both the left and right sides of the road or bridge. The buffer mechanism 3 can buffer and absorb energy when a vehicle hits the support guardrails 2, thereby improving safety. The rubber material is usually made of natural rubber or synthetic rubber and has good buffering, sound insulation and shock absorption functions.

[0033] In this embodiment, at least two buffer fixing blocks 33 are disposed inside at least two buffer cylinders 32, at least two buffer sliding rods 34 are disposed on the right side of at least two buffer fixing blocks 33, at least two buffer sliding rods 34 are slidably connected inside at least two buffer cylinders 32, at least two mounting plates 35 are fixed to the left side of support plate 36 by bolts, and the right side of at least two buffer sliding rods 34 is fixedly connected to the left side of at least two mounting plates 35.

[0034] In this embodiment, the connecting assembly includes at least two connecting pieces 371, at least two rotating rods 372, and at least two anti-collision cylinders 373. The at least two connecting pieces 371 are all disposed on the upper and lower sides of the right side of the support plate 36. The at least two rotating rods 372 are rotatably connected to the opposite side of the upper and lower connecting pieces 371 through bearings. The at least two anti-collision cylinders 373 are rotatably connected to the outside of the at least two rotating rods 372 through bearings.

[0035] In this embodiment, the supporting guardrail frame 2, fixing plate 31, buffer cylinder 32, buffer sliding rod 34, mounting plate 35, supporting plate 36, connecting piece 371, rotating rod 372 and anti-collision cylinder 373 can all be made of stainless steel, which can improve service life and structural stability, while reducing the possibility of rust, thereby improving the practicality of anti-collision devices for highway bridges.

[0036] In this embodiment, when a car is driving on the ground 1 and accidentally hits at least two anti-collision cylinders 373, each of the at least two anti-collision cylinders 373 is provided with a buffer rubber cylinder on its outer side. At the same time, at least two buffer fixing blocks 33 on the upper and lower sides can be compressed and buffered to absorb energy. Then, at least two buffer sliding rods 34 on the upper and lower sides slide inside the at least two buffer cylinders 32 on the upper and lower sides to buffer and absorb energy for the car.

[0037] In this embodiment, the rubber buffer block has high elasticity and large compression deformation, and can withstand repeated loads. In particular, its excellent buffering and vibration reduction performance has high application value. The rebound force provided by the spring is usually greater than that of the rubber. The buffering performance of the rubber is better, especially in absorbing impact and high-frequency vibration. The internal damping of the rubber is large, which can convert kinetic energy into heat energy and play the role of "buffering + energy absorption". This can improve the buffering performance of the anti-collision device for highway bridges. There are no fewer than two anti-collision cylinders 373 that can rotate on the outside of no fewer than two rotating rods 372. There are no fewer than two rotating rods 372 that can rotate on the opposite side of the upper and lower connecting pieces 371.

[0038] In this embodiment, at least two anti-collision cylinders 373 are provided with buffer cylinders on their outer sides. The buffer cylinders are rubber cylinders. At least two buffer cylinder bodies 32 are evenly distributed on the upper and lower sides of the right side of the fixing plate 31. At least two connecting pieces 371 are evenly distributed on the upper and lower sides of the right side of the support plate 36. The buffer cylinders and anti-collision cylinders 373 are fitted with gaps. At least two buffer fixing blocks 33 are all buffer rubber blocks. The top and bottom walls of the inner cavity of the buffer cylinder body 32 are provided with limiting grooves. The upper and lower limiting grooves are slidably connected to sliders. The opposite sides of the upper and lower sliders are fixedly connected to the upper and lower sides of the buffer sliding rod 34.

[0039] It should be noted that at least two crash barriers 373 can rotate, guiding vehicles toward the direction of travel on the highway bridge, reducing the impact force, and ensuring greater safety for people's property and lives. The length of the at least two crash barriers 373 is relatively long, which can improve the stable guidance of the vehicle. At the same time, by twisting the bolts on the right side of the fixing plate 31, the fixing plate 31 can be removed from the right side of the supporting guardrail frame 2, facilitating the maintenance of the buffer structure on the right side of the fixing plate 31.

[0040] The working principle of the above embodiments is as follows:

[0041] When a car is traveling on the ground 1 and accidentally hits at least two crash barriers 373, each of the at least two crash barriers 373 is equipped with a buffer rubber tube on its outer side. At the same time, at least two buffer fixing blocks 33 on the upper and lower sides can be compressed and absorb energy. Then, at least two buffer sliding rods 34 on the upper and lower sides slide inside the at least two buffer cylinders 32 on the upper and lower sides to absorb energy for the car. At the same time, at least two crash barriers 373 can rotate to guide the vehicle toward the direction of travel on the highway bridge, reducing the impact force and ensuring the safety of people's property and lives. The at least two crash barriers 373 are relatively long, which can enhance the stable guidance of the car. At the same time, by twisting the bolts on the right side of the fixing plate 31, the fixing plate 31 can be removed from the right side of the supporting guardrail frame 2, which facilitates the maintenance of the buffer structure on the right side of the fixing plate 31.
