[0017] The present invention will be further described below in conjunction with specific embodiments. Figures 1 to 4 As shown:
[0018] Embodiment 1: A bridge anti-collision device based on bridge safety performance comprises two clamping plates 1 installed on the inner and outer side walls of the connection between two box girders by bolts, so that the two clamping plates 1 are clamped at the connection between the two box girders, and two buffer rods 2 spaced up and down are slidably inserted on the two clamping plates 1, and the buffer rods 2 penetrate the box girder from the clamping plates 1 on the inner side walls of the box girder to the outside, which is conducive to improving the linkage of the two box girders, thereby enhancing the safety of the connection between them;
[0019] Both ends of the two buffer rods 2 extend to the outside of the two clamping plates 1. A connecting rod 3 is provided between the two buffer rods 2 located on the outside of the box beam. The setting of the connecting rod 3 can prevent the buffer rod 2 from sliding off the clamping plates 1.
[0020] The two buffer rods 2 located on the inner side of the box beam are sleeved with the same impact rod 4, and the buffer rod 2 is sleeved with a buffer spring 5 located between the impact rod 4 and the adjacent clamping plate 1. Through the setting of the buffer spring 5, when the impact rod 4 is hit, the vehicle can be buffered by a certain distance, thereby improving the safety of the box beam itself as much as possible and preventing the connection of the box beam from breaking.
[0021] Embodiment 2: A bridge anti-collision device based on bridge safety performance, comprising two clamping plates 1 installed on the inner and outer side walls of the connection between two box girders by bolts, so that the two clamping plates 1 are clamped at the connection between the two box girders, and two buffer rods 2 spaced apart from each other are slidably inserted on the two clamping plates 1, and two groups of buffer rods 2 spaced apart from each other are provided, and the buffer rods 2 penetrate the box girder from the clamping plates 1 on the inner side walls of the box girder to the outside, which is beneficial to improving the linkage of the two box girders, thereby enhancing the safety of the connection between them;
[0022] Both ends of the two buffer rods 2 extend to the outside of the two clamping plates 1. A connecting rod 3 is provided between the two buffer rods 2 located on the outside of the box beam. The connecting rod 3 is installed on the buffer rod 2 by bolts. The setting of the connecting rod 3 can prevent the buffer rod 2 from sliding off the clamping plates 1.
[0023] A water tank 6 is provided on the clamping plate 1 installed on the outer side of the box beam, and a push plate 7 is provided in the water tank 6. The push plate 7 is connected to the connecting rod 9 through a cross bar 8. The cross bar 8 extends to the outer side of the water tank 6. The connecting rod 9 of the cross bar 8 is sealed and connected to the water tank 6. With the cooperation of the push plate 7, the connecting rod 9 and the water tank 6, the buffer rod 2 can further provide resistance after being hit, so as to avoid the collision rod 4 from hitting the box beam as much as possible.
[0024] The two buffer rods 2 located on the inner side of the box beam are sleeved with the same impact rod 4, and one end of the buffer rod 2 is fixed with a fixing block for limiting the impact rod 4 by bolts, so as to prevent the impact rod 4 from falling off the buffer rod 2;
[0025] A buffer spring 5 is sleeved on the buffer rod 2 and is located between the impact rod 4 and the adjacent clamping plate 1. By setting the buffer spring 5, when the impact rod 4 is hit, the distance of the car can be buffered, thereby improving the safety of the box beam itself as much as possible and preventing the connection of the box beam from breaking;
[0026] Two support rods 10 are horizontally arranged on the clamping plate 1, which are respectively located at the upper and lower ends of the collision rod 4. The lower support rod 10 is cast together with the surface of the box beam through concrete, and the height of the upper support rod 10 is higher than that of a general vehicle. A slide groove 11 is arranged on the support rod 10 along the moving track of the collision rod 4 to further provide support for the collision rod 4.
[0027] The impact rod 4 is sleeved with a rubber pad 12 and a sponge pad 13, and the sponge pad 13 is sleeved on the outside of the rubber pad 12, so as to simply protect the vehicle in an accident.
[0028] Working principle:
[0029] 1. Clamp the two clamping plates 1 on the inner and outer sides of the connection of the two box beams respectively, and then fix them with bolts. Then drill a through hole for inserting the buffer rod 2 on the box beam to facilitate inserting the buffer rod 2 on the two clamping plates 1. The connecting rod 3 is installed on the two buffer rods 2 by bolts so that they are supported and connected with the cross bar 8 in the water tank 6. The buffer spring 5 and the collision rod 4 are sequentially sleeved on the two buffer rods 2. After the upper and lower support rods 10 are installed on the clamping plates 1 by bolts, the lower support rod 10 is cast together with the road surface by concrete, and the two ends of the collision rod 4 are respectively inserted into the slide grooves 11 corresponding to the support rod 10;
[0030] 2. After the impact rod 4 is hit, it slides on the buffer rod 2, and the buffer spring 5 can reduce the impact force of the impact rod 4. With the cooperation of the connecting rod 3 and the cross bar 8, the impact of the impact rod 4 can be further buffered, thereby ensuring the safety of the bridge as much as possible.
