As the main load-bearing structure of the bridge, the bridge pier plays a vital role in the structural safety of the bridge. With the development of society, cars, ships and other vehicles collide with bridge piers from time to time, causing damage to the pier structure, which in turn affects the overall safety of the bridge. In the prior art, in addition to increasing the strength of the bridge pier, an anti-ship collision system is usually set on the bridge pier to reduce the harm of the collision.

By arranging the anti-collision device on the surface of the bridge pier, the anti-collision device itself absorbs the energy generated by the impact force, reduces the impact of accidental collision on the bridge pier, and ensures the safety of the overall structure of the bridge.
[0004] However, when the device is hit by a ship, especially a side collision, the friction between the outer steel pipe layer and the ship will seriously damage the anti-rust layer on the surface of the ship, which has certain disadvantages.

DETAILED DESCRIPTION
[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0025] Embodiment 1:
[0026] like Figure 1-6 As shown, the pier anti-collision device provided by the utility model comprises: a first buffer mechanism 1, a second buffer mechanism 2 and a third buffer mechanism 3 which are sequentially installed from the outside to the inside, and the third buffer mechanism 3 is directly connected to the pier; the first buffer mechanism 1 comprises a mounting frame 4, on which a plurality of buffer wheels 5 are installed in a triangular distribution, and the buffer wheel 5 comprises a rotating shaft 17, and the rotating shaft 17 is rotatably connected to the mounting frame 4 through a bearing, and a hard pipe 18 is sleeved and installed on the rotating shaft 17, and a rubber sleeve 19 is provided on the hard pipe 18. When in use, when a ship collides with the pier, first the ship and the pier collide with each other. The outermost first buffer mechanism 1 is in contact, or more precisely, is in contact with the buffer wheel 5. No matter from which direction the ship collides, the buffer wheel 5 will rotate accordingly. The ship is guided by the triangularly arranged buffer wheels 5 and moves along the outer side of the arrangement direction of the buffer wheels 5, thereby turning the ship away from the bridge pier. The ship is in contact with the rubber sleeve 19 on the buffer wheel 5. When the rubber sleeve 19 is in contact with the ship, it will not damage the anti-rust layer on the surface of the ship. In addition, the rolling contact between the buffer wheel 5 and the ship further reduces the friction, so the destructive force on the anti-rust layer is smaller.
[0027] By providing the first buffer mechanism 1, the second buffer mechanism 2 and the third buffer mechanism 3, multiple buffering can be performed. By using a plurality of buffer wheels 5 arranged in a triangle, the ship can be conveniently guided to turn and stay away from the bridge piers. In addition, a rubber sleeve 19 is provided on the buffer wheel 5, which can significantly reduce the damage to the anti-rust layer on the surface of the ship caused by the impact.
[0028] Embodiment 2:
[0029] like Figure 2-4 As shown, the second buffer mechanism 2 includes a mounting groove 6 and a support plate 8 installed in the mounting groove 6. The side of the mounting groove 6 is opened and a cover plate 11 is installed, so that the support plate 8 can be placed into the mounting groove 6 from the side. Two guide rods 7 are installed in the mounting groove 6. The two ends of the guide rod 7 are respectively connected to the mounting groove 6 and the cover plate 11. The guide rod 7 passes through the support plate 8. Two first springs 9 are installed on the guide rod 7. The two first springs 9 are respectively arranged on both sides of the support plate 8. A plurality of connecting plates 10 are installed between the support plate 8 and the mounting frame 4. When in use, when the ship collides with the first buffer mechanism 1, due to the guidance of the buffer wheel 5, the mounting frame 4 receives a lateral reaction force, and then the support plate 8 is moved laterally through the connecting plate 10, thereby compressing the first spring 9 in front of it, so that the first spring 9 shrinks and absorbs energy, thereby laterally buffering the impact force.
[0030] By providing a second buffer mechanism 2 including a mounting groove 6, a guide rod 7, a support plate 8, a first spring 9, a connecting plate 10, and a cover plate 11, the impact force during a ship collision can be laterally buffered and energy absorbed, thereby reducing damage to the ship and bridge piers caused by the collision.
[0031] Embodiment 3:
[0032] like Figure 4 As shown, baffles 12 are installed on the upper and lower sides of the mounting groove 6, and a buffer pad is installed on the side of the baffle 12 facing the mounting frame 4. The two ends of the connecting plate 10 are horizontally rotatably connected to the mounting frame 4 and the support plate 8. When in use, when an impact occurs, the mounting frame 4 is subjected to force to rotate with the hinge axis of the connecting plate 10. Since there are multiple connecting plates 10, the mounting frame 4 approaches the support plate 8 until the mounting frame 4 hits the buffer pad on the baffle 12. The buffer pad absorbs energy and buffers, thereby reducing the impact on the support plate 8, and thereby reducing the impact on the guide rod 7.
[0033] By arranging a baffle 12 in the installation groove 6 and installing a buffer pad, energy can be further absorbed and the impact force can be reduced.
[0034] Embodiment 4:
[0035] like Figure 2As shown, the third buffer mechanism 3 includes a fixed seat 13, which is installed on the bridge pier. A plurality of guide holes 14 are opened on the fixed seat 13. A guide column 5 is slidably installed in the guide hole 14. One end of the guide column 15 is fixedly connected to the mounting groove 6. A second spring 16 is sleeved and installed on the guide column 15. The two ends of the second spring 16 are respectively fixedly connected to the mounting groove 6 and the fixed seat 13. When in use, the longitudinal component force generated during the collision acts on the mounting groove 6, so that the mounting groove 6 approaches the fixed seat 13, thereby causing the guide column 15 to slide into the guide hole 14 and compress the second spring 16. Through the contraction of the second spring 16, the longitudinal impact force is absorbed and buffered, thereby reducing the damage to the bridge pier and the ship caused by the impact.
[0036] By providing the third buffer mechanism 3 including the fixing seat 13, the guide hole 14, the guide column 15 and the second spring 16, it is possible to absorb and buffer the longitudinal impact, thereby reducing the damage to the bridge pier and the ship caused by the impact.
[0037] Working principle: When in use, when the ship collides with the bridge pier, the ship first contacts with the outermost first buffer mechanism 1, or more precisely, the buffer wheel 5. No matter from which direction the ship collides, the buffer wheel 5 will rotate accordingly. The ship is guided by the triangularly arranged buffer wheels 5 and moves along the outer side of the arrangement direction of the buffer wheels 5, thereby turning the ship away from the bridge pier, and the ship contacts with the rubber sleeve 19 on the buffer wheel 5. When the rubber sleeve 19 contacts the ship, it will not damage the anti-rust layer on the surface of the ship, and the rolling contact between the buffer wheel 5 and the ship further reduces the friction, so the destructive force on the anti-rust layer is smaller.
