Description

Technical Field

[0001] The present invention relates to the technical field of bridge safety protection, and particularly relates to an operation method of an impact device for protecting bridge piers, which is floating and convenient for replacing the impact surface. Background Art

[0002] Due to the booming development of the economy and transportation, more and more bridges are being built on navigable waterways, and they are getting larger and larger. There are even ultra-long cross-sea or island-linking bridges, which have made the original waterways smaller and narrower. Therefore, incidents of ships hitting bridge piers are often reported in newspapers or on TV around the world. Some minor collisions can be repaired, but once a major collision occurs, the consequences are unimaginable. To ensure the safety of ships and protect the bridge from damage, people have taken many measures and facilities to safeguard the bridge's safety.

[0003] In the existing floating impact devices for protecting bridge piers, there are problems such as the relatively complex later replacement of the anti-collision layer and the relatively high cost of replacement and maintenance. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art, and to propose an operation method of an impact device for protecting bridge piers, which is floating and convenient for replacing the impact surface.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: An operation method of an impact device for protecting bridge piers, which is floating and convenient for replacing the impact surface. The impact device for protecting bridge piers, which is floating and convenient for replacing the impact surface, includes a pier body.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention; the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" 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 a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Referring to Figure 1-3 , an embodiment provided by the present invention: an operation method of an impact device for protecting a bridge pier in a floating type and facilitating the replacement of an impact surface, including a pier body 1. An inner wire frame 2 is arranged on the outer diameter of the pier body 1. The inner wire frame 2 plays a role in connecting and fixing an elastic layer 3. The elastic layer 3 is fixedly connected to the outer surface of the inner wire frame 2. Since the material of the elastic layer 3 is very light and has the ability to float, it drives the whole device to float on the water surface, floating on the water surface whether the water level rises or falls. Connecting plates 4 are fixedly connected to the middle parts of the front and rear ends of the elastic layer 3. The connecting plates 4 play a role in fixing the anti-collision layers 7 at the left and right ends. T-shaped sliders 5 are fixedly connected to the left and right ends of the connecting plates 4. The T-shaped sliders 5 are all slidably connected inside T-shaped chutes 6. The T-shaped chutes 6 are respectively arranged inside the front and rear ends of the anti-collision layers 7. First mounting holes 9 are arranged in the middle parts of the upper and lower ends of the T-shaped sliders 5. Second mounting holes 10 are arranged at the positions corresponding to the first mounting holes 9 on the left and right sides of the front and rear ends of the anti-collision layers 7. Screws 11 are slidably connected inside the first mounting holes 9. The tails of the screws 11 all penetrate through the second mounting holes 10 and are all threadedly connected to nuts 8. When replacing the anti-collision layer 7, first, the screws 11 are disassembled from the nuts 8 and taken out from the second mounting holes 10 and the first mounting holes 9. Then, under the action of the sliding connection between the T-shaped sliders 5 on the connecting plates 4 and the T-shaped chutes 6 on the anti-collision layers 7, the damaged anti-collision layer 7 is disassembled and removed. Then, the new anti-collision layer 7 is installed through the sliding connection between the T-shaped sliders 5 and the T-shaped chutes 6. Finally, the screws 11 penetrate through the first mounting holes 9 and the second mounting holes 10 and are threadedly connected to the corresponding nuts 8 to realize the fixation of the replaced anti-collision layer 7.

[0028] The elastic layer 3 is made of rubber, and the floating of the whole device is realized through the rubber. There is a gap between the pier body 1 and the inner wire rack 2. When being impacted, the impact force is buffered through the gap between the pier body 1 and the inner wire rack 2 and the elastic layer 3 made of rubber, effectively protecting the bridge pier. One end of the inner side of the anti-collision layer 7 is slidably connected to the outer wall of the elastic layer 3, thus ensuring the normal replacement of the anti-collision layer 7. The nuts 8 are all arranged on the inner wall of the T-shaped chute 6. Openings are arranged at the positions corresponding to the inner side of the anti-collision layer 7 and the T-shaped chute 6. The openings ensure the normal sliding of the T-shaped slider 5 in the T-shaped chute 6. The screw rods 11 are all slidably connected to the inner wall of the second installation hole 10.

[0029] Working principle: When in use, since the material of the elastic layer 3 is very light and has the ability to float, it drives the whole device to float on the water surface. Whether the water level rises or falls, it floats on the water surface. At the same time, the anti-collision layers 7 at both ends are connected through the connecting plate 4. There will be boats hitting the bridge pier accidentally on both sides of the bridge. At this time, the anti-collision layer 7 is deformed, but the bridge pier is not damaged. When replacing the anti-collision layer 7, first, the screw rod 11 is removed from the nut 8 and taken out from the second installation hole 10 and the first installation hole 9. Then, under the action of the sliding connection between the T-shaped slider 5 on the connecting plate 4 and the T-shaped chute 6 on the anti-collision layer 7, the damaged anti-collision layer 7 is disassembled and removed. Then, the new anti-collision layer 7 is installed through the sliding connection between the T-shaped slider 5 and the T-shaped chute 6. Finally, the screw rod 11 passes through the first installation hole 9 and the second installation hole 10 and is threadedly connected to the corresponding nut 8 to fix the replaced anti-collision layer 7.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
