Description

Technical Field

[0001] The utility model belongs to the technical field of bridge anti-collision, and in particular relates to a bridge pier anti-collision structure capable of unloading force. Background Art

[0002] Bridges are an extremely important part of transportation routes. There are long bridge passages on rivers and land. The bridges on land are mainly viaducts, which are elevated by piers. The cross-sea bridges on the sea also use piers as supporting structures to provide a fulcrum for the bridge road above. Since the piers occupy a certain space, both the piers on land and the piers on the seabed are likely to collide with vehicles. Therefore, anti-collision structures are installed on some piers that are prone to collision to reduce losses during collision.

[0003] Most of the current anti-collision structures are surrounded by soft materials, which can play a buffering role when the bridge piers are hit. However, although the current anti-collision structures can effectively reduce the losses during collisions, the contact of the collision surfaces will still be subject to a large impact force, and the damage to the material itself is still high. In addition, the anti-collision structures of the bridge piers on the sea surface will be assimilated by the sea water due to being immersed in sea water for a long time, and are often difficult to observe, thereby increasing the chance of collision. Utility Model Content

[0004] The purpose of the utility model is to provide a bridge pier anti-collision structure with unloading force, so as to solve the problems that the existing anti-collision structure is subjected to a large impact force on the material when a collision occurs and the anti-collision structure immersed in seawater for a long time has no collision warning.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge pier anti-collision structure with unloading force, comprising an inner casing, a unloading ring is provided on the outside of the inner casing, and an external embedded groove is provided on the side wall of the inner casing, an internal protruding ring is provided on the inner wall of the unloading ring, a middle beam is provided on the outside of the unloading ring, and a first buffer element and a second buffer element are installed between the middle beam and the unloading ring.

[0006] Preferably, the first cushioning elements and the second cushioning elements are interlaced with each other and are arranged in a circular pattern around the center point of the inner casing.

[0007] Preferably, fixing kits are installed on both sides of the first buffer element and the second buffer element, and an outer box is provided on the outer side of the center beam.

[0008] Preferably, the outer wall of the outer box is provided with a floating box of a different color, and the surface wall of the floating box of the different color is installed with a fixing belt, and the floating box of the different color is fixedly connected to the outer box through the fixing belt.

[0009] Preferably, a suspension rod is installed above the unloading ring, and the different-colored floating boxes are distributed in a circular array with the center point of the outer box.

[0010] Preferably, the inner protruding ring matches the outer embedded groove, and the inner casing and the unloading ring have the same height.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The utility model is provided with a force unloading ring, and an internal protruding ring is installed on the surface wall of the force unloading ring, and an external embedded groove is opened on the surface wall of the inner casing, and the internal protruding ring is located inside the external embedded groove, and there is no fixed structure between them. When in use, since there is no fixed structure between the internal protruding ring on the inner wall of the force unloading ring and the external embedded groove on the surface wall of the inner casing, the traction structure of the boom will be torn off and rotated when subjected to external impact, and the force unloading effect is achieved by rotation, thereby avoiding damage caused by excessive impact force of the colliding object.

[0013] (2) The utility model installs a different-color floating box on the surface wall of the outer box through a fixing belt. The different-color floating box needs to be sprayed with a coating before use. The anti-corrosion and water-resistant coating is used on the surface wall of the different-color floating box. At the same time, the color of the coating is set to a color that conflicts with the surrounding environment, which increases the warning effect and allows passing ships to be observed from a long distance. The control space for adjusting the angle of the ship is increased. At the same time, when facing a small collision, the different-color floating box can directly shrink after being subjected to force to avoid contact between the collision object and the internal metal structure, thereby reducing impact damage.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0020] See also Figures 1-4 As shown, the utility model provides the following technical solutions: a bridge pier anti-collision structure with unloading force, comprising an inner casing 1, a unloading ring 2 is provided on the outside of the inner casing 1, and an external embedded groove 12 is opened on the side wall of the inner casing 1, an internal protruding ring 11 is provided on the inner wall of the unloading ring 2, a middle beam 3 is provided on the outside of the unloading ring 2, and a first buffer original 8 and a second buffer original 9 are installed between the middle beam 3 and the unloading ring 2, the first buffer original 8 and the second buffer original 9 form a layer of buffer structure, and a total of two layers of buffer structure are provided, which are respectively located between the unloading ring 2 and the middle beam 3 and between the middle beam 3 and the outer casing 4, the inner casing 1 and the unloading ring 2 are in contact but not fixed, and when the unloading ring 2 is subjected to too much force, it will rotate on the outside of the inner casing 1, thereby unloading the impact force during the collision, thereby reducing the impact.

[0021] Furthermore, the first buffer element 8 and the second buffer element 9 are staggered with each other and are distributed in a circular array with the center point of the inner casing 1. The first buffer element 8 and the second buffer element 9 are both made of rubber ring material. When impacted, the buffer element on the impact surface is compressed, and the outer casing 4 on the outside will pull the buffer element away from the impact surface after being subjected to force. The impact force during the impact is buffered by the buffer element, thereby reducing the loss caused by the impact.

[0022] Furthermore, fixing kits 10 are installed on both sides of the first buffer component 8 and the second buffer component 9, and an outer box 4 is provided on the outside of the central beam 3. The outer box 4 is made of hollow metal. When the outer layer of the heterogeneous floating box 5 is damaged and the impactor contacts the outer box 4, its hollow structure increases the buffering performance.

[0023] Specifically, the outer wall of the outer box 4 is provided with a different-colored floating box 5, and the surface wall of the different-colored floating box 5 is installed with a fixing belt 6. The different-colored floating box 5 is fixedly connected to the outer box 4 through the fixing belt 6. The different-colored floating box 5 is made of soft material. When it is subjected to a collision with a smaller impact, it will directly bounce off the colliding object, avoiding the operation of the internal buffer structure, thereby increasing the service life of the internal buffer structure.

[0024] It is worth noting that a boom 7 is installed above the unloading ring 2, and the different-colored floating boxes 5 are distributed in a circular array with the center point of the outer box 4. The surface wall of the different-colored floating boxes 5 is sprayed with anti-corrosion material to form a warning-colored coating, which increases the ship's driver's warning psychology when observing, so as to react and avoid conflicts between the waterway and the bridge pier.

[0025] Furthermore, the internal protruding ring 11 matches the external embedded groove 12, the inner sleeve box 1 and the unloading ring 2 have the same height, and the unloading ring 2 and the internal protruding ring 11 can adopt a two-section structure. After the sections are divided, they are clamped on the outside of the inner sleeve box 1, and then the two sections of the unloading ring 2 and the internal protruding ring 11 are fixed.

[0026] The working principle and use process of the utility model are as follows: When using the utility model, the inner casing 1 is fixed to the bottom of the pier, and the unloading ring 2 is installed on the outside of the inner casing 1, so that the inner protruding ring 11 inside the unloading ring 2 is inserted into the outer embedded groove 12 of the surface wall of the inner casing 1, and then the central beam 3 is erected using the suspender 7, and the fixing kit 10 is installed on both sides of the second buffer element 9 and the first buffer element 8, and the first buffer element 8 and the second buffer element 9 are installed between the central beam 3 and the unloading ring 2 through the fixing kit 10, and the outer casing 4 is sleeved on the outside of the central beam 3, and the first buffer element 8 and the second buffer element 9 are also installed between the central beam 3 and the outer casing 4. The impact element 9 is used, and finally the different-colored floating box 5 is installed on the outside of the outer box 4 using a fixing belt 6. When a collision occurs, the two layers of the first buffer element 8 and the second buffer element 9 are pulled to buffer the force, thereby reducing the impact force of the collision on the bridge pier. At the same time, after the collision, the unloading ring 2 will rotate on the outside of the inner box 1 under the action of the impact force, thereby driving the external structure to rotate, thereby unloading the force, thereby reducing the impact force of the collision contact. The external different-colored floating box 5 has a striking color, so that the driver of the ship can observe the position of the bridge pier from a distance, thereby providing a more regular turning time and reducing the possibility of collision.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
