Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge piers, and in particular to an anti-collision component for surface protection of bridge piers. Background Technology
[0002] Bridge piers are a crucial component of bridge structures, primarily serving to support the superstructure and effectively transfer the load from the bridge's upper structure to the foundation. The design and construction quality of bridge piers directly affect the stability, safety, and durability of the bridge. Structurally, bridge piers come in various types, such as cylindrical piers, rectangular piers, and thin-walled piers. Cylindrical piers are relatively easy to construct and have an aesthetically pleasing appearance; rectangular piers possess greater bending stiffness; and thin-walled piers are suitable for some long-span bridges.
[0003] Bridge piers are mostly exposed, making them vulnerable to impacts from vehicles in traffic accidents. In severe cases, this can lead to vehicle total loss and damage to the structural stability of the piers. Even minor collisions can cause damage to the piers. Therefore, a collision protection component for the surface protection of bridge piers is proposed to address these issues. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an anti-collision component for the surface protection of bridge piers, aiming to improve the existing technology where piers are easily impacted by vehicles in the event of an accidental traffic accident, which can lead to vehicle scrapping and damage to the structural stability of the piers. Moreover, even minor collisions can cause damage to the piers.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1-5 An embodiment of this utility model includes a pier body 1, the surface of which is provided with six sets of limiting rings 2, the inner sides of every two sets of limiting rings 2 are in contact with each other, and the front and rear sides of each set of limiting rings 2 are fixedly installed with mounting blocks 3, which are detachably installed by bolts, and anti-collision mechanisms 4 are provided on both sides of the pier body 1.
[0032] The anti-collision mechanism 4 is used to reduce the impact force on the pier body 1. When a traffic accident occurs, the vehicle will be damped by the anti-collision mechanism 4 to prevent the impact force on the vehicle and the pier body 1 from being buffered, thereby reducing the impact force on the vehicle and the pier body 1.
[0033] Reference Figure 1-5The anti-collision mechanism 4 includes a connecting box 41. A rotating block 42 is fixedly installed on the outer side of the limiting ring 2. A rotating plate 43 is rotatably installed inside the rotating block 42 via a shaft pin. Connecting rods 44 are slidably installed inside the four sets of rotating plates 43. The outer end of the connecting rod 44 is fixedly installed on the inner side of the connecting box 41. The outer side of the limiting ring 2 is fixedly installed on the inner side of the rotating block 42. Through the cooperation of the connecting box 41, rotating block 42, rotating plate 43 and connecting rod 44, when a traffic accident occurs, the vehicle will hit the connecting box 41. At this time, the connecting box 41 will move inward due to the impact. The movement of the connecting box 41 will cause the rotating block 42 to slide inside the rotating plate 43. This reduces the impact force generated when a vehicle collides with the pier body 1. The anti-collision mechanism 4 also includes an anti-collision plate 45. A connecting block 46 is fixedly installed on the inner side of the anti-collision plate 45. The inner side of the connecting block 46 extends into the interior of the connecting box 41 and is fixedly installed with an airbag 47. The inner side of the airbag 47 is fixedly installed on the inner side of the inner wall of the connecting box 41. Through the cooperation of the anti-collision plate 45, the connecting block 46 and the airbag 47, when the vehicle is involved in an accident, the vehicle will collide with the anti-collision plate 45. At this time, the anti-collision plate 45 will move inward under the force. The inward movement of the anti-collision plate 45 will cause the connecting block 46 to compress the airbag 47, thereby reducing the impact force of the vehicle. A first spring is fixedly installed on the inner side of the connecting block 46. A damper 48 is fixedly installed on the inner end of a first spring damper 48 and the outer side of a connecting box 41. The first spring damper 48 allows the connecting block 46 to compress the first spring damper 48 when it moves inward. When the first spring damper 48 is compressed by a vehicle, it reduces the impact force, thereby reducing the damage to the pier body 1 in the event of a vehicle accident. A second spring damper 49 is fixedly installed on the inner side of the inner wall of the rotating plate 43. The outer end of the second spring damper 49 is fixedly installed on the inner end of a connecting rod 44. The second spring damper 49 allows the connecting box 41 to compress the connecting rod 44 when it moves inward. The second spring damper 49 in the movable compressible rotating plate 43 can reduce the impact force on the connecting rod 44. The top and bottom of the inner wall of the connecting box 41 are fixedly installed with a return spring 5. The outer end of the airbag 47 at the inner end of the return spring 5 is fixedly installed. The top of the airbag 47 is connected to the air inlet pipe 6. Through the cooperation of the return spring 5 and the air inlet pipe 6, when the anti-collision plate 45 is subjected to a small impact force, the connecting block 46 will squeeze the airbag 47. When the airbag 47 deflates, under the action of the return spring 5, the airbag 47 can be pulled outward, so that air is drawn into the airbag 47 from the outside, so that the airbag 47 becomes full.
[0034] Reference Figure 1-5The outer side of the anti-collision plate 45 is provided with a protective plate 7. The four corners of the inner side of the anti-collision plate 45 are detachable and installed by bolts. The protective plate 7 is made of rubber, which can improve the buffering effect on the vehicle.
[0035] Working principle: When a traffic accident occurs, the vehicle will impact the protective plate 7. The protective plate 7 will move inward under the force, causing the anti-collision plate 45 to move inward as well. The inward movement of the anti-collision plate 45 will cause the connecting block 46 to compress the airbag 47. At the same time, the connecting block 46 will compress the first spring damper 48, which will provide the first shock absorption for the vehicle. When the connecting block 46 compresses the airbag 47, it will provide the second shock absorption for the vehicle. Finally, when the airbag 47 deflates, it will compress the connecting box 41 and move inward. The connecting box 41 will compress the connecting rod 44, which will compress the second spring damper 49. Thus, the vehicle will be shock absorbed three times, which can effectively reduce the impact between the vehicle and the pier body 1.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
