Description

Technical Field

[0001] This application relates to the technical field of bridge pier protection, and in particular to a floating bridge pier anti-collision structure. Background Technology

[0002] A floating impact device for bridge piers is a type of anti-collision device installed around the piers of bridges spanning rivers, seas, and oceans. It can rise and fall along the axis of the pier by relying on its own buoyancy as the water level rises and falls, and floats on the water surface, always at the impact face, i.e., the height of the ship's impact.

[0003] The existing floating anti-collision mechanism for bridge piers is quite wide, occupies a large area of ​​the waterway, and affects the passage of ships, especially when navigating at night.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the existing floating anti-collision mechanisms for bridge piers are relatively wide and occupy a large area of ​​the river channel. Utility Model Content

[0005] The purpose of this application is to provide a floating bridge pier anti-collision structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a floating bridge pier anti-collision structure with the following technical solution:

[0007] A floating bridge pier anti-collision structure includes an anti-collision block body, which is sleeved on the outside of the bridge pier. A groove is formed on the side of the anti-collision block body away from the bridge pier, and a sealing plate fits into the groove. Multiple pop-out mechanisms are fixed to the sealing plate near the anti-collision block body. Each pop-out mechanism includes a first telescopic sleeve, a limiting block, an L-shaped block, a second telescopic sleeve, and a fixing block. The first telescopic sleeve is fixed to the sealing plate near the anti-collision block body, and a limiting block is fixed to the top of the first telescopic sleeve. A corresponding L-shaped block is provided on the top of the limiting block. The second telescopic sleeve is fixed to the bottom of the L-shaped block away from the limiting block, and a fixing block is fixed to the bottom of the second telescopic sleeve. The fixing block is fixedly connected to the anti-collision block body. A connecting plate is fixedly connected to the bottom of the anti-collision block body, and a floating chamber is fixedly connected to the bottom of the connecting plate.

[0008] By adopting the above technical solution, the floating chamber is set at the bottom of the anti-collision block body, which can reduce the width of the anti-collision block body and reduce the occupation of the river channel area. When the ejection mechanism is impacted, it ejects and applies the impact force to the first telescopic sleeve, which has a better buffering effect.

[0009] Preferably, the sealing plate has a maintenance port on the side near the ejection mechanism.

[0010] By adopting the above technical solution, after the ejection mechanism is ejected due to a large impact, it can be reset through the inspection port, which facilitates its later use.

[0011] Preferably, the anti-collision block body has multiple buffer mechanisms fixed on the side near the bridge pier. The buffer mechanism includes two symmetrical third telescopic sleeves, a fourth telescopic sleeve, and a roller. The two third telescopic sleeves are hinged and fixed inside the anti-collision block body, and a fourth telescopic sleeve is hinged between the two third telescopic sleeves. A roller is fixed at the end of the third telescopic sleeve away from the anti-collision block body.

[0012] By adopting the above technical solution, when the anti-collision block body is impacted, the pressure acts on the anti-collision block body, the third telescopic sleeve and the fourth telescopic sleeve are compressed by the pressure, and the roller slides on the surface of the pier, which plays a good buffering role.

[0013] Preferably, the first telescopic sleeve, the second telescopic sleeve, the third telescopic sleeve, and the fourth telescopic sleeve each include a telescopic rod and a spring sleeved on the thin end of the telescopic rod.

[0014] By adopting the above technical solution, the spring can provide a buffering effect when subjected to pressure.

[0015] Preferably, the buoyancy chamber is a hollow box.

[0016] By adopting the above technical solution, it is convenient to generate an upward buoyancy force on the anti-collision block body.

[0017] Preferably, the two anti-collision block bodies are fixedly connected by connecting plates and bolts.

[0018] By adopting the above technical solution, it is convenient to protect the entire bridge pier.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By setting up the floating chamber and the ejection mechanism, the floating chamber is set at the bottom of the anti-collision block body, which can reduce the width of the anti-collision block body and reduce the occupation of the river channel area. The ejection mechanism is deployed when impacted, and the impact force is applied to the first telescopic sleeve, which has a better buffering effect.

[0021] 2. The buffer mechanism helps to ensure that when the anti-collision block is impacted, the pressure acts on the anti-collision block, and the third and fourth telescopic sleeves are compressed by the pressure, causing the rollers to slide on the surface of the pier, thus playing a better buffering role.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a floating bridge pier anti-collision structure, referring to... Figure 1-4 The system includes a crash block body 1, which is fitted onto the outside of a bridge pier 2. A groove 3 is formed on the side of the crash block body 1 away from the bridge pier 2. A sealing plate 4 fits into the groove 3. Multiple pop-out mechanisms 5 are fixed to the side of the sealing plate 4 near the crash block body 1. Each pop-out mechanism 5 includes a first telescopic sleeve 51, a limiting block 52, an L-shaped block 53, a second telescopic sleeve 54, and a fixing block 55. The first telescopic sleeve 51 is fixed to the side of the sealing plate 4 near the crash block body 1. A limiting block 52 is fixed to the top of the first telescopic sleeve 51. A corresponding L-shaped block 53 is provided on the top of the limiting block 52. A second telescopic sleeve 54 is fixed to the bottom of the L-shaped block 53 away from the limiting block 52. A fixing block 55 is fixed at the bottom and is fixedly connected to the anti-collision block body 1. When the anti-collision block body 1 is subjected to pressure impact, it squeezes the sealing plate 4, causing the first telescopic sleeve rod 51 to compress. The L-shaped locking block 53 disengages from the limiting locking block 52, so that the sealing plate 4 reacts on the boat under the action of the first telescopic sleeve rod 51, which plays a certain role in protecting the boat and reducing the impact force. A connecting plate 6 is fixedly connected to the bottom of the anti-collision block body 1, and a floating chamber 7 is fixedly connected to the bottom of the connecting plate 6. The floating chamber 7 is a hollow box. The two anti-collision block bodies 1 are fixedly connected by connecting pieces and bolts. The floating chamber 7 is set on the bottom plate of the anti-collision block body 1, which greatly reduces the width of the anti-collision block body 1 and thus reduces the occupation of the river channel area.

[0029] Reference Figure 1 The sealing plate 4 has a maintenance port 8 on the side near the pop-out mechanism 5. After an impact, the pop-out mechanism 5 can be reset through the maintenance port 8.

[0030] Reference Figure 1-4 The anti-collision block body 1 is fixed with multiple buffer mechanisms 9 on the side near the pier 2. Each buffer mechanism 9 includes two symmetrical third telescopic sleeves 91, a fourth telescopic sleeve 92, and a roller 93. The two third telescopic sleeves 91 are hinged to the inside of the anti-collision block body 1, and the fourth telescopic sleeve 92 is hinged between the two third telescopic sleeves 91. The roller 93 is fixed to the end of the third telescopic sleeve 91 away from the anti-collision block body 1. The first telescopic sleeve 51, the second telescopic sleeve 54, the third telescopic sleeve 91, and the fourth telescopic sleeve 92 each include a telescopic rod and a spring sleeved at the thin end of the telescopic rod. When the anti-collision block body 1 is impacted, pressure is applied to the anti-collision block body 1. The third telescopic sleeves 91 and the fourth telescopic sleeve 92 are compressed by the pressure, the spring is compressed, and the pressure is absorbed. The roller 93 slides on the surface of the pier 2, which plays a good buffering role.

[0031] The implementation principle of a floating bridge pier anti-collision structure in this application is as follows:

[0032] When using the device, the anti-collision block body 1 is fixed to the outside of the pier 2 by connecting plates and bolts. The floating chamber 7 is submerged in the water, with part of the anti-collision block body 1 underwater and part above the water surface, protecting the pier 2. This greatly reduces the width of the anti-collision block body 1, thereby reducing the occupation of the river surface. When a ship collides with the anti-collision block body 1, the sealing plate 4 is squeezed, causing the L-shaped locking block 53 of the ejection mechanism 5 to disengage from the limiting locking block 52. Under the action of the first telescopic sleeve 51, the sealing plate 4 reacts to the ship, providing a certain degree of protection for the ship and reducing the impact force. The third telescopic sleeve 91 and the fourth telescopic sleeve 92 of the buffer mechanism 9 are compressed, causing the spring to compress and absorb the pressure. The roller 93 slides on the surface of the pier 2, providing a good buffering effect and improving the protection of the pier 2. During regular maintenance, the condition of the ejection mechanism 5 can be checked through the maintenance port 8, making it easy to reset the L-shaped locking block 53.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
