Description

Technical Field

[0001] This utility model relates to the field of bridge pier anti-collision technology, specifically to an elastic anti-collision device for bridge piers in waterways. Background Technology

[0002] Currently, the intermediate support structure of multi-span bridges is called a pier. Piers are divided into solid piers, column piers, and frame piers, etc. According to the plan shape, they can be divided into rectangular piers, pointed piers, and circular piers. The materials used to build piers can be wood, stone, concrete, reinforced concrete, steel, etc. Piers are mainly composed of a cap and a pier body, while abutments are mainly composed of a cap and abutment body. The function of the cap is to distribute and evenly transmit the large and concentrated force from the bridge span support to the pier body and abutment body.

[0003] Currently, when bridge piers are impacted by external forces such as ships, structural damage may occur, such as cracks or fractures in the internal steel bars and concrete, causing the piers to lose their load-bearing capacity. Once the piers are damaged, their ability to support the bridge deck will be affected, and the bridge deck may collapse or break due to loss of support. This will not only endanger the safety of vehicles and pedestrians on the bridge, but also cause traffic interruption and affect the road's traffic capacity. Utility Model Content

[0022] Please see Figure 1-3 This utility model provides a technical solution: an elastic anti-collision device for bridge piers in waterways, comprising:

[0023] A fixed base 1 is provided, and a fixed support body 2 is fixedly embedded in the center of the inner wall of the fixed base 1;

[0024] An elastic anti-collision structure is installed on the fixed pier 2;

[0025] The elastic anti-collision structure includes a rotating frame 3, an anti-collision frame 4, and multiple auxiliary springs 5. The inner wall of the rotating frame 3 is rotatably sleeved on the fixed pier 2, and the outer wall of the anti-collision frame 4 is slidably embedded in the rotating frame 3. Two rubber tires 6 are fixedly sleeved on the inner wall of the rotating frame 3, and the outer walls of the two rubber tires 6 are fixedly embedded in the anti-collision frame 4. The ends of the multiple auxiliary springs 5 ​​that are far apart from each other are all fixed in the anti-collision frame 4, and the ends of the multiple auxiliary springs 5 ​​that are close to each other are all fixed in the rotating frame 3.

[0026] The supporting structure is located between the two rubber tires 6.

[0027] In this implementation plan: the fixed pier 2 serves as the bridge pier support, and the inner wall of the rotating frame 3 rotates on the fixed pier 2. In conjunction with the anti-collision frame 4, the impact is redirected, thereby mitigating the impact. The two internal rubber tires 6 provide buffer elasticity between the rotating frame 3 and the anti-collision frame 4, further mitigating the impact. Multiple auxiliary springs 5 ​​are used to increase the elastic connection between the rotating frame 3 and the anti-collision frame 4, further strengthening the buffer elasticity between them. This effectively protects the bridge pier from damage caused by ship collisions, while reducing the impact on ships and ensuring the safety of water traffic.

[0028] Specifically, a fixed top plate 7 is fixedly installed on the top of the outer wall of the fixed pier 2, and the outer wall of the rotating frame 3 is rotatably embedded between the fixed top plate 7 and the fixed base 1.

[0029] In this embodiment, the top support area of ​​the fixed pier 2 can be increased by fixing the top plate 7.

[0030] Specifically, the outer wall of the anti-collision frame 4 is fixedly fitted with an elastic ring 8, which is made of rubber.

[0031] In this embodiment, the elastic ring 8 makes the surface of the anti-collision frame 4 elastic, which can protect the anti-collision frame 4 and also protect the impact part of the ship.

[0032] Specifically, the bottom of the outer wall of the fixed base 1 is provided with a fixed base plate 9, and the outer wall of the fixed base plate 9 is provided with multiple mounting holes at equal intervals along the circumferential surface.

[0033] In this embodiment, the fixing base 1 can be fixed to the bridge pier base by means of multiple mounting holes on the fixing base plate 9.

[0034] Specifically, the support structure includes two support rings 10 and multiple support rods 11, with the two support rings 10 respectively attached to two rubber tires 6 on their opposite sides.

[0035] In this embodiment, two rubber tires 6 are supported by two support rings 10 to prevent the two rubber tires 6 from moving toward the center.

[0036] Specifically, the outer walls of multiple support rods 11 are fixed between two support rings 10 and are evenly spaced along the circumferential surface.

[0037] In this embodiment, multiple support rods 11 can fix the two support rings 10 together.

[0038] In use, the fixed pier 2 serves as the bridge pier supporting the bridge. The inner wall of the rotating frame 3 rotates on the fixed pier 2, working in conjunction with the anti-collision frame 4 to change the direction of the impact, thereby mitigating the impact. The two internal rubber tires 6 provide buffer elasticity between the rotating frame 3 and the anti-collision frame 4, further mitigating the impact. Multiple auxiliary springs 5 ​​enhance the elastic connection between the rotating frame 3 and the anti-collision frame 4, further strengthening the buffer elasticity between them. This effectively protects the bridge pier from damage caused by ship collisions, while also reducing the impact on ships and ensuring the safety of water traffic. The fixed top plate 7 increases the top support area of ​​the fixed pier 2. The elastic ring 8 provides elasticity to the surface of the anti-collision frame 4, protecting both the anti-collision frame 4 and the impact point from the ship. Multiple mounting holes on the fixed base plate 9 allow the fixed base 1 to be installed and fixed on the bridge pier base. Multiple support rods 11 secure the two support rings 10 together, which support the two rubber tires 6, preventing them from moving towards the center.
