[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The bridge pier anti-collision device of the utility model has at least one large anti-collision component tightly installed at the position of the bridge pier 9. Preferably, the bridge pier anti-collision device has at least two large anti-collision components arranged vertically on the bridge pier 9. In actual use, different numbers of large anti-collision components are selected according to needs, that is, one layer of large anti-collision components can be tightly installed in the vertical direction of the bridge pier 9, two layers of large anti-collision components can be tightly installed in the vertical direction of the bridge pier 9, and three layers of large anti-collision components can be tightly installed in the vertical direction of the bridge pier 9, and so on. It should be noted that the large anti-collision component can be directly installed in the vertical direction of the bridge pier 9, or it can be installed in the vertical direction of the bridge pier 9. The protective column outside the bridge pier 9 can also be installed on the wall, guardrail and other places.
[0024] The large anti-collision component is composed of several small anti-collision components. The small anti-collision component includes a bracket and an anti-collision roller 1 installed on the bracket. Anti-collision rollers 1 of different diameters and numbers can be selected as needed. The bracket includes an upper support plate 2, a lower support plate 3, and a fixing member 4 for connecting the upper support plate 2 and the lower support plate 3. Specifically, one end of the fixing member 4 is welded and fixed on the upper support plate 2, and the other end of the fixing member 4 is welded and fixed on the lower support plate 3. The fixing member 4 can be a fixing rod, or a metal plate fixed on the inner side of the upper support plate 2 and the lower support plate 3. The upper end of the anti-collision roller 1 is rotatably installed in the mounting hole of the upper support plate 2, and the lower end of the anti-collision roller 1 is rotatably installed in the mounting hole of the lower support plate 3. The center line of the anti-collision roller 1 is biased toward the outer side of the upper support plate 2 and the outer side of the lower support plate 3, so that the anti-collision roller 1 protrudes from the outer side of the upper support plate 2 and the outer side of the lower support plate 3, and a gap is left between the anti-collision roller 1 and the bridge pier 9 so that the anti-collision roller 1 can rotate freely. When ships, vehicles, etc. collide with the bridge pier anti-collision device, the ships, vehicles, etc. will only collide with the anti-collision roller 1, and will not collide with the upper support plate 2 and the lower support plate 3. The reason why there is a gap between the anti-collision roller 1 and the bridge pier 9 is to ensure that the anti-collision roller 1 will rotate when hit by ships, vehicles, etc., so as to decompose the impact force of the ships, vehicles, etc. on the bridge pier 9. The upper support plate 2 and the lower support plate 3 are fixed on the bridge pier 9.
[0025] Two adjacent small anti-collision components are connected to each other, specifically, two adjacent small anti-collision components are connected to each other through hinges or metal parts. The main body of the large anti-collision component is made of rigid metal material, that is, the anti-collision roller 1, the upper support plate 2, the lower support plate 3, the fixing part 4, etc. are made of rigid metal material.
[0026] It should be noted that the upper support plate 2 and the lower support plate 3 do not need to be connected by the fixing member 4. When there is no fixing member 4, the upper support plate 2 and the lower support plate 3 can be installed on the bridge pier separately.
[0027] The outer surface of the anti-collision roller 1 is wrapped with an elastic sleeve 5, such as: the elastic sleeve 5 is made of rubber material. The inner ring of the upper support plate 2 and the inner ring of the lower support plate 3 are respectively provided with an elastic pad 6, the cross section of the elastic pad 6 is U-shaped, the elastic pad 6 is made of rubber material, and the opening of the U-shaped elastic pad 6 is clamped on the upper support plate 2 or the lower support plate 3. The shape of the upper support plate 2 is the same as that of the lower support plate 3, the upper support plate 2 and the lower support plate 3 are both placed flat, and the upper support plate 2 in the same anti-collision small component is located directly above the lower support plate 3. The two adjacent upper support plates 2 are connected to each other by a hinge or a strapping belt 10, and the two adjacent lower support plates 3 are connected to each other by a hinge or a strapping belt 10, such as: the two adjacent upper support plates 2 are connected to each other by an upper hinge 7, and the two adjacent lower support plates 3 are connected to each other by a lower hinge 8. The upper support plate 2 and the lower support plate 3 are fixed to the pier 9 by expansion screws or strap fasteners. When ships, vehicles, etc. collide with the anti-collision roller 1, the anti-collision roller 1 generates rotation and rolling to prevent the ships, vehicles, etc. from colliding hard with the anti-collision roller 1, thereby protecting the safety of the bridge pier 9, and also protecting the safety of the ships, vehicles, etc.
[0028] The anti-collision device for the bridge pier has a very reasonable structural design. It is not easy for ships, vehicles, etc. to collide with the axis line of a certain anti-collision roller 1. That is, when ships, vehicles, etc. collide with a certain anti-collision roller 1, there will be a deflection force, which drives the anti-collision roller 1 to rotate, and deflects the impact force of ships, vehicles, etc. on the bridge pier outward, thereby greatly decomposing the impact force of ships, vehicles, etc. on the bridge pier, extending the service life of the bridge pier, and protecting the safety of the bridge pier, ships, vehicles, etc.
[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
