Description

Technical Field

[0001] The utility model relates to the technical field of bridges, and in particular to a self-floating bridge pier anti-collision device. Background Art

[0002] Ship collisions with bridges occur frequently in some places. Such accidents have caused a series of adverse consequences such as bridge collapse, ship damage, casualties, environmental pollution, and interruption of water and land transportation trunk lines, which have had an adverse impact on society and caused serious losses to the national economy.

[0003] Based on this, installing an anti-collision device on the outer wall of the pier can effectively buffer the impact of ships on the pier. Such as independent anti-collision piers, steel structure fenders, FRP anti-collision buoys, etc. However, most traditional anti-collision devices are directly fixed on the outside of the pier, so it is necessary to install guard plates in most areas of the outer wall of the pier to maintain the protection capability as the water level rises and falls. However, the cost of installing the guard plates is very high, and the structure is complex and difficult to maintain. In addition, most of the existing anti-collision devices are one-piece structures, so when they are impacted, they often need to be repaired or replaced on a large scale. Therefore, a pier protection device that is easy to install and cost-controlled can be designed. Utility Model Content

[0004] The purpose of the utility model is to provide a self-floating bridge pier anti-collision device, which can rise and fall with the rise and fall of water level. A buffer plate of a certain height can have a complete protection function, and installation and maintenance are more convenient and cost-controllable.

[0005] The embodiments of the utility model are realized by the following technical scheme: the self-floating bridge pier anti-collision device of the utility model comprises a plurality of buffer plates arranged around the outer periphery of the bridge pier; adjacent buffer plates are detachably connected; the buffer plates comprise a hollow frame and fillers arranged inside the frame.

[0006] Furthermore, a plurality of energy dissipation devices are provided in the frame, and the energy dissipation devices are arranged vertically.

[0007] Furthermore, a gap is provided between the buffer plate and the bridge pier.

[0008] Furthermore, a plurality of shock-absorbing blocks are provided on the inner wall of the buffer plate.

[0009] Furthermore, the shock absorbing block is U-shaped, and both ends of the shock absorbing block are connected to the inner wall of the buffer plate.

[0010] Furthermore, it also includes an annular enclosure, which is arranged around the outer walls of the plurality of buffer plates, and the enclosure is fixedly connected to the buffer plates.

[0011] Furthermore, a lifting lug is provided on the upper end of the buffer plate.

[0012] Furthermore, the filler is a polymer material.

[0013] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects: the self-floating bridge pier anti-collision device of the utility model, when in use, first hoist a single buffer plate to the side of the bridge pier, and then connect the adjacent buffer plates together, so that the buffer plates are surrounded in a ring around the bridge pier, so as to protect the bridge pier and the ship. Since the whole is composed of a plurality of buffer plates, the density of the buffer plate is lower, and it can float on the water surface, and rise and fall with the rise and fall of the water level. Only a buffer plate of a certain height needs to be set to have a complete protective function, so a single buffer plate can be better replaced or maintained after being hit. And the buffer plate is composed of a frame structure and filler, which can better absorb the impact after being hit, reducing the damage to the bridge pier and the ship.

[0024] Example

[0025] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 3 As shown in the figure, the self-floating bridge pier anti-collision device of this embodiment includes a plurality of buffer plates 10 arranged around the periphery of the bridge pier 30; adjacent buffer plates 10 are detachably connected; the buffer plates 10 include a hollow frame 11 and a filler 12 arranged inside the frame 11. Specifically, when in use, a single buffer plate 10 is first hoisted to the side of the bridge pier 30, and then adjacent buffer plates 10 are connected together, so that the buffer plates 10 surround the periphery of the bridge pier 30 in a ring shape (as shown in the attached figure). Figure 2As shown in the figure, the pier 30 and the ship are protected. Since the whole is composed of a plurality of buffer plates 10, a single buffer plate 10 can be replaced or maintained better after being hit. The buffer plate 10 is composed of a frame 11 structure and a filler 12, so that the density of the buffer plate 10 is lower, and it can float on the water surface and rise and fall with the rise and fall of the water level. Only a buffer plate 10 of a certain height is required to have a complete protective function, which can better absorb the impact after being hit and reduce the damage to the pier 30 and the ship.

[0026] In this embodiment, a plurality of energy dissipation devices 13 are arranged in the frame 11, and the energy dissipation devices 13 are arranged vertically. Specifically, the energy dissipation devices 13 are mainly hollow round tube structures, which can play a good buffering role when impacted. Therefore, the energy dissipation devices 13 can not only reduce the overall weight of the buffer plate 10, so that it floats better on the water surface, but also can better absorb the energy of the impact when impacted.

[0027] In this embodiment, a gap is provided between the buffer plate 10 and the bridge pier 30. A plurality of shock-absorbing blocks 21 are provided on the inner wall of the buffer plate 10. The shock-absorbing blocks 21 are U-shaped, and both ends of the shock-absorbing blocks 21 are connected to the inner wall of the buffer plate 10. Specifically, the buffer plate 10 does not come into direct contact with the bridge pier 30. By providing the shock-absorbing blocks 21 in the gap, the shock-absorbing blocks 21 are in contact with the bridge pier 30, which can reduce the large area of ​​contact between the buffer plate 10 and the bridge pier 30, thereby reducing the friction between the two, so that the buffer plate 10 as a whole can rise and fall more smoothly with the rise and fall of the water surface. And when impacted, the shock-absorbing blocks 21 can also play a certain buffering role.

[0028] In this embodiment, an annular enclosing plate 22 is further included, and the enclosing plate 22 is disposed around the outer walls of the plurality of buffer plates 10, and the enclosing plate 22 is fixedly connected to the buffer plates 10. Specifically, the enclosing plate 22 is mainly used to protect the buffer plates 10 and make the buffer plates 10 more integrated.

[0029] The buffer plate 10 in this embodiment is provided with a lifting lug at its upper end. Specifically, the lifting lug is used for lifting during installation or replacement.

[0030] The filler 12 in this embodiment is a polymer material. Specifically, the polymer material not only has certain strength and toughness, but also is not easy to corrode and has good stability.

[0031] In summary, the self-floating bridge pier anti-collision device of this embodiment, when in use, first hoist a single buffer plate 10 to the side of the bridge pier 30, and then connect the adjacent buffer plates 10, so that the buffer plates 10 surround the bridge pier 30 in a ring shape, thereby protecting the bridge pier 30 and the ship. Since the whole is composed of a plurality of buffer plates 10, it is easier to replace or maintain a single buffer plate 10 after being hit. In addition, the buffer plate 10 is composed of a frame 11 structure and a filler 12, which can better absorb the impact after being hit, thereby reducing the damage to the bridge pier 30 and the ship.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
