Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to an anti-collision bridge. Background Art

[0002] Highway transportation is the main artery of the national economy. With the rapid development of highway transportation in China in recent years, the road route settings are intricate, and the construction of many overpasses and overcrossing bridges has also increased accordingly. For the construction of overcrossing bridges in some areas, due to technical or conditional constraints, the bridge piers are often set in the middle of the road under the bridge. In many accidents, the bridge piers are damaged and severely affect the traffic, and even lead to more serious traffic accidents.

[0003] At present, in order to improve the safety of existing bridges, anti-collision piers are usually installed near the bridge piers to replace the bridge piers to come into contact with vehicles and avoid direct collision between vehicles and bridge piers. However, the existing anti-collision piers are usually made of concrete or plastic materials, with high hardness and poor buffering performance. When the vehicle does not have a violent collision with it but only scratches it, due to the vehicle scraping the surface of the anti-collision pier, it is easy to cause damage to the vehicle or the surface of the anti-collision pier, and the use effect is not good. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-collision bridge to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions. The anti-collision bridge includes a bridge body. A plurality of bridge piers are arranged at the bottom of the bridge body. An anti-collision sleeve is arranged on the bridge pier. An embedding groove for embedding the anti-collision sleeve is circumferentially opened on the side wall of the bridge pier. A rotating sleeve is rotatably connected inside the embedding groove. A plurality of positioning pins are arranged on the outer side wall of the rotating sleeve. A plurality of positioning holes for inserting the positioning pins are opened on the inner side wall of the anti-collision sleeve.

[0006] As a further setting of the utility model, the anti-collision sleeve includes a first sleeve body and a second sleeve body, and the first sleeve body and the second sleeve body are connected by a connecting component.

Detailed Embodiment

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 As shown in the figure, an anti-collision bridge includes a bridge body 1. A number of bridge piers 2 are provided at the bottom of the bridge body 1, and an anti-collision sleeve is provided on the bridge piers 2. An embedding groove 3 for embedding the anti-collision sleeve is circumferentially formed on the side wall of the bridge pier 2, and a rotating sleeve 4 is rotatably connected inside the embedding groove 3. A number of positioning pins 5 are provided on the outer side wall of the rotating sleeve 4, and a number of positioning holes 6 for inserting the positioning pins 5 are formed on the inner side wall of the anti-collision sleeve. When installing the anti-collision sleeve on the bridge pier 2, the anti-collision sleeve can be first embedded in the embedding groove 3, so that the positioning pins 5 are inserted into the positioning holes 6 accordingly. Through the cooperation of the positioning pins 5 and the positioning holes 6, the connection between the anti-collision sleeve and the rotating sleeve 4 can be realized. Since the rotating sleeve 4 can rotate inside the embedding groove 3, the anti-collision sleeve can rotate relative to the bridge pier 2. Through the setting of the anti-collision sleeve, it can replace the bridge pier 2 to come into contact with the vehicle, avoiding the direct collision between the vehicle and the bridge pier 2, playing an anti-collision role. And when the vehicle does not collide violently with the anti-collision sleeve but only rubs against it, due to the operation of the vehicle scraping the surface of the anti-collision sleeve, it will drive the anti-collision sleeve to rotate accordingly. Then, through the active rotation of the anti-collision sleeve to unload the force, the impact force generated by friction can be reduced, so as to reduce the damage to the surface of the vehicle or the anti-collision sleeve, playing a better protection role, and the use effect is better. Among them, a rotating groove 16 is circumferentially formed on the inner wall of the embedding groove 3, and a rotating ring 17 rotatably connected inside the rotating groove 16 is provided on the inner side wall of the rotating sleeve 4. Then the rotating ring 17 can rotate in the rotating groove 16, so as to ensure the smooth rotation of the rotating sleeve 4 inside the embedding groove 3. And both the rotating sleeve 4 and the rotating ring 17 are made of stainless steel materials, with high strength and hardness, and are corrosion-resistant and have good durability.

[0022] Please refer to Figure 1 、 Figure 2As shown in the figure, the anti-collision sleeve includes a first sleeve body 7 and a second sleeve body 8, and the first sleeve body 7 and the second sleeve body 8 are connected by a connecting component. When the anti-collision sleeve is deformed and damaged due to long-term use, the connecting component can be removed to release the connection between the first sleeve body 7 and the second sleeve body 8. Then, the old first sleeve body 7 and the second sleeve body 8 can be removed from the bridge pier 2 respectively, and new first sleeve body 7 and second sleeve body 8 can be replaced. Then, they are connected through the connecting component. The operation is relatively convenient and simple, and the anti-collision function of the bridge is always ensured. The connecting component includes a connecting rod 9. Threaded rods 10 are arranged at both ends of the connecting rod 9, and nuts 11 are threadedly connected to the threaded rods 10. A number of through holes 12 for the threaded rods 10 to penetrate are formed in the first sleeve body 7 and the second sleeve body 8. When installing the anti-collision sleeve, the first sleeve body 7 and the second sleeve body 8 can be inserted into the embedding groove 3 and combined into one body. Then, the connecting component is inserted so that the threaded rods 10 pass through the through holes 12. Then, the nuts 11 are threadedly connected to the threaded rods 10. Through the locking of the nuts 11, the first sleeve body 7 and the second sleeve body 8 can be fixedly connected together, and the connection firmness is relatively good. When disassembling the anti-collision sleeve, the nuts 11 can be screwed out from the threaded rods 10, and then the connecting component can be removed, so that the first sleeve body 7 and the second sleeve body 8 can be separated. Through this setting, the disassembly and assembly of the anti-collision sleeve are relatively convenient and simple, which is convenient for the replacement of the anti-collision sleeve. A number of grooves 13 for the nuts 11 to be embedded are formed on the outer side walls of the first sleeve body 7 and the second sleeve body 8. When the nuts 11 are threadedly connected to the threaded rods 10, the nuts 11 can be continuously screwed until they are embedded in the grooves 13. Through the limitation of the nuts 11 by the grooves 13, the nuts 11 can be hidden to avoid loosening caused by accidental touch, thus ensuring the installation firmness of the anti-collision sleeve on the bridge pier 2. Among them, the first sleeve body 7 and the second sleeve body 8 both include an outer shell 14 and a buffer layer 15 arranged inside the outer shell 14. The buffer layer 15 is made of polyurethane foam material and has good elasticity, so as to play a buffering role and avoid deformation of the anti-collision sleeve caused by too large impact force, thus ensuring the anti-collision effect of the anti-collision sleeve. The outer shell 14 is made of engineering plastic material, with good strength and toughness and corrosion resistance, thus ensuring the durability of the anti-collision sleeve.
