[0002] With the vigorous development of transportation construction, the number of cross-river and cross-river bridges is gradually increasing, and the collision accidents of ships against bridges at home and abroad are also increasing continuously. Since bridges, ships and anti-collision facilities are all expensive engineering buildings, in order to ensure the safety of ships and bridges themselves, it is particularly important to reasonably design the anti-collision of bridge piles.

[0003] After retrieval, Chinese Patent Publication No.: CN214089951U discloses a fender for bridge pile anti-collision, including a bearing platform, a foundation pile, a fender and a steel support. The bearing platform is arranged on the foundation pile, the fender is arranged on one side of the bearing platform, the steel support is triangular, and the two right-angled sides of the steel support are respectively connected with the bearing platform and the fender.

[0029] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0030] Referring to Figures 1-3 , an embodiment provided by the present utility model: a fender for road and bridge anti-collision, including a road and bridge body 1 and a connecting steel plate 2. A plurality of grooves 104 are formed on the side surface of the road and bridge body 1. A slide bar 103 is installed inside the plurality of grooves 104. A sliding block 105 is slidably connected to the surface of the slide bar 103. A plurality of arc-shaped buffer plates 101 matching the sliding block 105 are installed on the inner side of the connecting steel plate 2. Both ends of the plurality of arc-shaped buffer plates 101 are connected to the sliding block 105. A buffer spring 102 is connected to the surface of the slide bar 103 on the outer side of the sliding block 105. By the combined use of the arc-shaped buffer plate 101, the buffer spring 102, the slide bar 103, the groove 104, the sliding block 105 and the connecting steel plate 2, the impact force received by the road and bridge body 1 can be buffered, the influence caused by the impact force on the road and bridge body 1 can be reduced, the anti-collision effect of the road and bridge body 1 can be improved, the problem of damage to the road and bridge body 1 can be effectively prevented, and the service life of the road and bridge body 1 can be prolonged; A plurality of buffer components are installed on the other side of the connecting steel plate 2. The other end of the buffer component is connected to a fender mounting seat 3. An anti-collision fender body 4 is installed on the other side of the fender mounting seat 3. By the combined use of the connecting steel plate 2, the fender mounting seat 3, the anti-collision fender body 4 and the buffer component, the received impact can be initially buffered, the buffer and anti-collision effects can be improved, and the ship can be protected, reducing the possibility of damage to the hull.

[0031] Referring to Figure 2 , the buffer component includes a plurality of buffer sleeves 202. The plurality of buffer sleeves 202 are evenly distributed and installed on one side of the connecting steel plate 2. A first spring 204 is installed inside the plurality of buffer sleeves 202. A connecting rod 201 is slidably connected inside the plurality of buffer sleeves 202. The other end of the connecting rod 201 is connected to the fender mounting seat 3; A limiting block 203 is connected to one end of the connecting rod 201 located inside the buffer sleeve 202. The other end of the buffer sleeve 202 is connected to the limiting block 203. When the fender mounting seat 3 is impacted, the fender mounting seat 3 drives the plurality of connecting rods 201 and the limiting blocks 203 to move inside the buffer sleeve 202. The limiting block 203 squeezes the first spring 204. Through the elastic action of the first spring 204, the impact force can be initially buffered. And increasing the stiffness coefficient of the first spring 204 can reduce the deformation degree of the first spring 204 and effectively buffer the impact force.

[0032] Referring to Figure 2, on both ends of the side of the connecting steel plate 2 where the fender mounting seat 3 is located, two groups of support seats 6 are installed. Inside the two groups of support seats 6, a connecting block 501 is slidably connected. At one end of the connecting block 501 outside the support seat 6, a protective plate 5 is installed. Inside the two groups of support seats 6, a chute 601 is provided. Inside the chute 601, a second spring 502 is installed. The other end of the second spring 502 is connected to the connecting block 501. Through the protective plate 5 and the connecting block 501, the contact area with the ship can be increased, the area for buffering the impact force can be increased, and the ship and the bridge body 1 can be effectively protected.

[0033] Refer to Figure 1 and 4 , on the surface of the anti-collision fender body 4, multiple groups of buffer pads 401 are installed. Inside the anti-collision fender body 4, multiple groups of reinforcing ribs 402 are installed. Both ends of the multiple groups of reinforcing ribs 402 are connected to the side of the fender mounting seat 3. The multiple groups of buffer pads 401 and the reinforcing ribs 402 can improve the strength of the anti-collision fender body 4 and extend the service life of the anti-collision fender body 4. The top of the connecting steel plate 2 is connected to a connecting plate 7. On the surface of the connecting plate 7, multiple groups of fixing bolts 701 are threadedly connected. The bottoms of the multiple groups of fixing bolts 701 are connected to the bridge body 1. The connecting plate 7 and the fixing bolts 701 facilitate the staff to connect the connecting steel plate 2 to the bridge body 1 and improve the stability of the connecting steel plate 2.

[0034] Working principle: When in use, first connect the multiple groups of arc-shaped buffer plates 101 inside the connecting steel plate 2 to the sliding blocks 105, and then connect the fixing bolts 701 to the top of the bridge body 1, so as to install the connecting steel plate 2 on the side of the bridge body 1. When the anti-collision fender body 4 is impacted, the anti-collision fender body 4 and the protective plate 5 come into contact with the ship. The anti-collision fender body 4 initially buffers the impact force. The anti-collision fender body 4 pushes the fender mounting seat 3 to move towards the bridge body 1, and the first spring 204 can buffer the impact force again to reduce the impact strength. When the connecting steel plate 2 moves, it will drive the arc-shaped buffer plates 101 to move, causing the arc-shaped buffer plates 101 to deform. When the arc-shaped buffer plates 101 deform, both ends drive the sliding blocks 105 to move on the surface of the sliding rods 103, and the buffer springs 102 buffer the movement of the sliding blocks 105, thereby reducing the impact on the bridge body 1 caused by the impact force and extending the service life of the bridge body 1.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
