Description

Technical Field

[0001] This invention relates to the field of bridge protection technology, specifically to a composite layered structure bridge pier anti-collision buffer device. Background Technology

[0002] With the development of the economy and transportation, large-scale cross-sea and cross-river bridges are constantly being built. The rivers and seas where these bridges are located are busy waterways with complex conditions such as wind, waves, and currents. Therefore, the bridge piers inevitably bear the risk of collision from ships, so protective measures need to be taken for the bridge piers.

[0003] However, existing bridge pier anti-collision buffer devices have some problems in use. These devices are usually fixed on the surface of the bridge pier and located in the water. In the event of floods or droughts, the water level will change, and the existing protective buffer devices will not be able to adapt to the water level changes, thus reducing the applicability of the devices. At the same time, the existing anti-collision buffer devices are not easy to install and disassemble, and are not convenient to install protective devices for bridge piers of different sizes. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this invention is to provide a composite layered structure bridge pier anti-collision buffer device.

[0006] Preferably, a plurality of second elastic plates are provided between the two thick steel plates, and a second T-shaped plate is fixedly connected to the rear side of each of the second elastic plates. A second T-shaped groove is opened on the front side of each of the second elastic plates. Two first T-shaped grooves are opened on the front side of the rear thick steel plate, and two first T-shaped plates are fixedly connected to the rear side of the front thick steel plate. The first T-shaped plates and the second T-shaped plates are located in adjacent first T-shaped grooves and second T-shaped grooves.

[0007] Preferably, the alloy steel U-shaped frame has slots on both the left and right sides, and the slots are interconnected with the inner cavity of the alloy steel U-shaped frame. Connecting straps are fixedly connected to both the left and right sides of the front rubber frame. The side of the connecting strap away from the front rubber frame passes through the adjacent slot and is fixedly connected to a limiting block. The inner cavity of each limiting block has two through slots. Restraining straps are fixedly connected to both the left and right sides of the rear rubber frame. The side of the restraining strap away from the rear rubber frame passes through the adjacent slot and the side of the restraining strap away from the rear rubber frame passes through two adjacent through slots.

[0008] Preferably, threaded rods are fixedly connected to the top of the rubber frame near the left and right sides. Threaded cylinders are threaded to the outer edges of the threaded rods. A rectangular frame is fitted around the outer edges of two adjacent threaded cylinders, with the two rectangular frames positioned left and right.

T-shaped annular grooves are formed on the outer edges of the threaded cylinders, and two T-shaped blocks are movably connected within each T-shaped annular groove. A connecting disk is fixedly connected to the side of each T-block away from the threaded rod.

[0009] Preferably, the top of each alloy steel U-shaped frame has two first threaded holes, and the top of each thick steel plate has two second threaded holes. A first elastic plate is attached to the top of each alloy steel U-shaped frame near both the left and right sides. A hinge is provided on the side of each first elastic plate away from the thick steel plate. The first elastic plate is movably connected to the top of the alloy steel U-shaped frame via the hinge. A connecting groove is provided on the top of each first elastic plate. A first bolt is threaded into the first threaded hole, and a second bolt is threaded into the second threaded hole. The tips of the first and second bolts penetrate adjacent connecting grooves.

[0010] Preferably, the top of the alloy steel U-shaped frame is provided with several blind holes, and several reinforcing bars are fixedly connected to the top of the thick steel plate, with the end of the reinforcing bar away from the thick steel plate located in the adjacent blind hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the interplay between structures such as an alloy steel U-shaped frame, a rubber frame, a thick steel plate, and a floating plate. The device is first assembled by holding the connecting straps and restraining straps, then placing the rubber frame inside the alloy steel U-shaped frame. The connecting straps and restraining straps pass through slots on one side of adjacent alloy steel U-shaped frames. The aluminum foam board and polyethylene foam board are located within the U-shaped grooves inside the rubber frame. After this initial assembly, the two alloy steel U-shaped frames are moved to the bridge pier. The floating plate allows the device to float on the water surface. The restraining straps are then passed through the through-slots on the limiting block. The initial installation of the rubber frames on both the front and rear sides allows the device to be closer to the pier surface. Next, a rectangular frame is taken out and fitted over the surfaces of the two threaded rods. The threaded cylinder is then pulled, and the cylinder is stretched via a T-block and connecting disc, aligning its bottom with the threaded rod. The rotating disc is then adjusted, rotating the cylinder to the surface of the threaded rod, further limiting the position of the rubber frame. Finally, the rear thick steel plate is placed on one side of the rear alloy steel U-shaped frame, with the top reinforcing bar of the rear thick steel plate placed within the rear alloy steel U-shaped frame. The thick steel plate is initially installed in the blind hole at the top of the frame. Then, multiple second elastic plates are taken out, and the second T-shaped plates on the back of the second elastic plates are placed in the adjacent T-slots. Multiple second elastic plates are installed in sequence. Finally, the front thick steel plate is taken out, and the first T-shaped plate on the front of the front thick steel plate is placed in the T-slot on the front of the foremost second elastic plate. The top reinforcing bar of the front thick steel plate is placed in the blind hole at the top of the front alloy steel U-shaped frame. The first elastic plate is then swung to place it horizontally on top of the alloy steel U-shaped frame, the rubber frame, and the thick steel plate. The first bolt is taken out, passed through the connecting groove on the first elastic plate, and rotated to the threaded hole at the top of the alloy steel U-shaped frame. The second bolt is then taken out, passed through the connecting groove on the first elastic plate, and rotated to the threaded hole at the top of the thick steel plate. This further limits the installation of the thick steel plate, making the thick steel plate and multiple second elastic plates fit against the surface of the pier. When the water level changes, the floating plate will drive the top device to change with the water level, improving the applicability and protection range of the device. Attached Figure Description

The first T-plates 22 and the second T-plates 23 are located in the adjacent first T-slots and the second T-slots. The alloy steel U-shaped frame 2 has slots on both the left and right sides. The slots are interconnected with the inner cavity of the alloy steel U-shaped frame 2. Connecting straps 9 are fixedly connected to both the left and right sides of the front rubber frame 3.

The inner cavity of the limiting block 10 has two through slots. Binding straps 11 are fixedly connected to both the left and right sides of the rear rubber frame 3. The side of the binding strap 11 away from the rear rubber frame 3 passes through the adjacent slot and the side of the binding strap 11 away from the rear rubber frame 3 passes through the two adjacent through slots. Threaded rods 12 are fixedly connected to the top of the rubber frame 3 near the left and right sides. Threaded cylinders 14 are threadedly connected to the outer edges of the threaded rods 12. A rectangular frame 8 is fitted around the outer edges of two adjacent threaded cylinders 14, arranged left and right. The top of the threaded cylinder 14 passes through the rectangular frame 8, and a rotating disk 13 is fixedly connected to the top of the threaded cylinder 14. T-shaped annular grooves are formed on the outer edges of the threaded cylinders 14, and two T-shaped blocks 16 are movably connected within each T-shaped groove.

Two first threaded holes are formed on the top of the alloy steel U-shaped frame 2, and two second threaded holes are formed on the top of the thick steel plate 4. The top of the alloy steel U-shaped frame 2 near the left and right sides... A first elastic plate 5 is fitted together, and a hinge is provided on the side of the first elastic plate 5 away from the thick steel plate 4. The first elastic plate 5 is movably connected to the top of the alloy steel U-shaped frame 2 through the hinge. A connecting groove is opened on the top of the first elastic plate 5. A first bolt 6 is threadedly connected to the first threaded hole, and a second bolt 7 is threadedly connected to the second threaded hole. The top ends of the first bolt 6 and the second bolt 7 pass through the adjacent connecting groove. Several blind holes are opened on the top of the alloy steel U-shaped frame 2. Several steel bars 20 are fixedly connected to the top of the thick steel plate 4. The end of the steel bar 20 away from the thick steel plate 4 is located in the adjacent blind hole. Three springs 17 are provided in the inner cavity of the rectangular frame 8. One end of the spring 17 is fixedly connected to one side of the adjacent connecting plate 15 and the side wall of the inner cavity of the rectangular frame 8.

[0016] Working principle: Before the device starts working, it is first assembled. Hold down the connecting strap 9 and the restraining strap 11, and place the rubber frame 3 inside the alloy steel U-shaped frame 2. The connecting strap 9 and the restraining strap 11 pass through the slots on one side of the adjacent alloy steel U-shaped frame 2. The aluminum foam board 18 and the polyethylene foam board 19 are located in the U-shaped grooves inside the rubber frame 3. After the initial assembly is completed, move the two alloy steel U-shaped frames 2 to the bridge pier. The float 1 makes the device float on the water surface. Pass the restraining strap 11 through the through slot on the limiting block 10, thus achieving the initial installation of the rubber frames 3 on both the front and rear sides. This allows the device to get closer to the pier surface. Then, the rectangular frame 8 is taken out and placed over the surfaces of the two threaded rods 12. The threaded cylinder 14 is pulled, and through the T-block 16 and connecting disc 15, the spring 17 is stretched, aligning the bottom of the threaded cylinder 14 with the threaded rod 12. The rotating disc 13 is adjusted, rotating the threaded cylinder 14 to the surface of the threaded rod 12, further limiting the rubber frame 3. Then, the rear thick steel plate 4 is placed on one side of the rear alloy steel U-shaped frame 2, with the top reinforcing bar 20 of the rear thick steel plate 4 placed on top of the rear alloy steel U-shaped frame 2. The thick steel plate 4 is initially installed in the blind hole. Then, multiple second elastic plates 21 are taken out, and the second T-shaped plates 23 on the back side of the second elastic plates 21 are placed in the adjacent T-shaped grooves. Multiple second elastic plates 21 are installed in sequence. Finally, the front thick steel plate 4 is taken out, and the first T-shaped plate 22 on the front side of the front thick steel plate 4 is placed in the T-shaped groove on the front side of the foremost second elastic plate 21. The steel bar 20 at the top of the front thick steel plate 4 is placed in the blind hole at the top of the front alloy steel U-shaped frame 2, and the first elastic plate 5 is swung to place the first elastic plate 5 horizontally on the alloy steel U-shaped frame 2. Take out the first bolt 6 from the top of the rubber frame 3 and the thick steel plate 4, pass the first bolt 6 through the connecting groove on the first elastic plate 5, and rotate it to the threaded hole at the top of the alloy steel U-shaped frame 2. Then take out the second bolt 7, pass the second bolt 7 through the connecting groove on the first elastic plate 5, and rotate it to the threaded hole at the top of the thick steel plate 4. This further limits the installation of the thick steel plate 4, so that the thick steel plate 4 and multiple second elastic plates 21 are attached to the surface of the pier. When the water level changes, the floating plate 1 will drive the device at the top to change with the water level, thereby improving the applicability and protection range of the device.
