Description

Technical Field

[0001] This invention relates to a highly secure protective device for bridge protection. Background Technology

[0002] To prevent structural damage to bridge piers from collisions with ships, and to protect ships as much as possible to minimize losses, protective measures must be taken for the bridge piers.

[0003] Because bridges are subject to construction errors, some existing protective structures cannot fit snugly against the piers. This lack of fit prevents the protective structure from evenly distributing stress upon impact, leading to stress concentration at certain points and reduced structural stability. Furthermore, some protective structures, while employing multi-stage buffering mechanisms, only transmit force between these individual buffers, resulting in poor structural stability during impacts. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned technical problems, the present invention provides a highly safe protective device for bridge protection.

[0005] The technical solution adopted by this invention to solve its technical problem is: a high-safety protective device for bridge protection, which is wrapped around the outer wall of a bridge pier, including an outer shell and vertically arranged rubber columns inside the outer shell. The outer shell is arc-shaped and has at least three sections, which are sequentially spliced ​​to form a cylindrical shell. Each section of the outer shell has a corresponding arc-shaped buffer block. Each arc-shaped buffer block is provided with several compression units. The compression unit includes a rubber pad, a support pad, a connecting block, and a connecting column. The rubber pad abuts against the outer wall of the bridge pier, and the connecting column is fixed to the arc-shaped buffer block. The rubber pad and the support pad... The pads are connected by connecting blocks, and the supporting pads are set on the connecting columns. The supporting pads are made of rigid material. Adjacent shell sections are connected by connecting components, which include connecting buckles. Each connecting buckle has at least two tenons, and the tenons on the same connecting buckle are inserted into the outer walls of the adjacent shell sections. Each shell section has arc-shaped notches at both ends, and adjacent shell sections are spliced ​​together to form arc-shaped grooves. A portion of the rubber column fits into the arc-shaped grooves, and the arc-shaped buffer blocks corresponding to adjacent shell sections are connected by rubber columns. The ends of the arc-shaped buffer blocks abut against the outer walls of the rubber columns.

[0006] Each section of the outer shell is connected to the internal buffer block by an X-shaped hinge structure. The X-shaped hinge structure includes two hinge rods, each with rollers at both ends. The two hinge rods are cross-hinged in the middle and connected to each other by a torsion spring in the middle. The roller at one end of the hinge rod abuts against the outer wall of the buffer pad, and the roller at the other end of the hinge rod abuts against the inner wall of the outer shell.

[0007] Each extrusion unit is evenly distributed on the arc-shaped buffer block, and each extrusion unit faces the central axis of the cylindrical shell.

[0008] The rubber pad has rubber granules at both ends of its surface facing the pier, and the rubber granules abut against the outer wall of the pier.

[0009] The outer shell is made of a rigid material.

[0010] Each arc-shaped groove contains a rubber column, which is cylindrical.

[0011] The connecting buckle has a fluorescent strip or indicator light on its surface away from the outer casing.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] Bridge piers are typically cylindrical. This invention provides a highly secure protective device for bridge protection, which wraps around the outer wall of the pier. Specifically, the protective device includes a shell 1 and vertically arranged rubber columns 2 inside the shell 1. The shell 1 is arc-shaped and has at least three sections. Figure 1 The device shown has three outer shell sections 1, which are sequentially spliced ​​together to form a cylindrical shell. Each outer shell section 1 contains a corresponding arc-shaped buffer block 3, resulting in three arc-shaped buffer blocks 3. Each arc-shaped buffer block 3 is equipped with several compression units 4. Figure 1 In the illustrated embodiment, each arc-shaped buffer block 3 is provided with three compression units 4. Each compression unit 4 includes a rubber pad 4-1, a support pad 4-2, a connecting block 4-3, and a connecting column 4-4. The rubber pad 4-1 abuts against the outer wall of the pier, and the connecting column 4-4 is fixed to the arc-shaped buffer block 3. The rubber pad 4-1 and the support pad 4-2 are connected by the connecting block 4-3. The support pad 4-2 is mounted on the connecting column 4-4 and is made of a rigid material. To better conform to the outer wall of the pier, the rubber pad 4-1 has an arc-shaped surface. The rubber pad 4-1 and the supporting pad 4-2 combine soft and hard materials. The rubber pad is made of elastic material and is directly attached to the bridge pier, which can reduce the hard damage to the bridge pier and also play a certain role in buffering. The surface area of ​​the supporting pad 4-2 is larger than that of the rubber pad 4-1, which can more evenly receive the force transmitted from the rubber pad 4-1. The supporting pad 4-2 and the rubber pad 4-1 are connected by a connecting block 4-3. The connecting block 4-3 is block-shaped and has a large volume, which can absorb part of the force. The connecting column 4-4 fixes the entire extrusion unit 4 on the arc-shaped buffer block 3.

[0020] Adjacent shell sections 1 are connected by a connecting assembly 5, which includes a connecting buckle 5-1. Each connecting buckle 5-1 has at least two tenons 5-2, and the tenons 5-2 on the same connecting buckle 5-1 are inserted into the outer walls of the adjacent shell sections 1. Figure 1 and 3 As shown, two adjacent shell sections 1 are connected by two tenons 5-2 on the same connecting buckle 5-1. One tenon 5-2 is inserted into one shell section 1, and the other tenon 5-2 is inserted into the other shell section 1, thereby achieving the connection and fixation between the two shell sections 1.

[0021] Each shell segment 1 has arc-shaped notches at both ends, and adjacent shell segments 1 are spliced ​​together to form an arc-shaped groove. A portion of the rubber pillar 2 fits into the arc-shaped groove, and the arc-shaped buffer blocks 3 corresponding to adjacent shell segments 1 are connected by the rubber pillar 2. The ends of the arc-shaped buffer blocks 3 abut against the outer wall of the rubber pillar 2. The rubber pillar 2 abuts against the arc-shaped groove, the end of one arc-shaped buffer block 3, and the end of another arc-shaped buffer block 3 at these three points, achieving a three-point stable structure. Furthermore, all three points are in surface contact, resulting in a more stable structure.

[0022] Each segment of the outer shell 1 is connected to the internal buffer block via an X-shaped hinge structure 6. The X-shaped hinge structure 6 includes two hinge rods 6-1, each with a roller 6-2 at both ends. The two hinge rods 6-1 are cross-hinged at the middle and connected by a torsion spring at their midpoints. The roller 6-2 at one end of each hinge rod 6-1 abuts against the outer wall of the arc-shaped buffer block 3, while the roller 6-2 at the other end abuts against the inner wall of the outer shell 1. The X-shaped hinge structure 6 deforms under stress, achieving a buffering and damping effect. The roller 6-2 at the end of the hinge rod 6-1, with its smaller size relative to the outer wall of the arc-shaped buffer block 3 and the inner wall of the outer shell 1, allows for a faster response to deformation.

[0023] To ensure more even force distribution, each extrusion unit 4 is evenly distributed on the arc-shaped buffer block 3, and each extrusion unit 4 faces the central axis of the cylindrical shell.

[0024] Rubber granules 4-5 are provided at both ends of the surface of the rubber pad 4-1 facing the pier, and the rubber granules 4-5 abut against the outer wall of the pier. The rubber granules 4-5 are elastic and can play a certain role in cushioning. At the same time, since the rubber granules 4-5 are located at both ends of the surface of the rubber pad 4-1, it is equivalent to setting small claws at both ends of the rubber pad 4-1. Since the surface of the pier is often not a smooth and flat surface, the rubber granules 4-5 can grip the outer wall of the pier. At the same time, when force is applied, the rubber pad 4-1 is squeezed inward, which allows the rubber pad 4-1 to absorb the unevenness of the pier surface and makes the rubber pad 4-1 less likely to slip.

[0025] For protection, the outer shell 1 is made of a rigid material. The curved buffer block 3 can be made of an elastic material to provide cushioning.

[0026] Each arc-shaped groove contains a rubber column 2, which is cylindrical.

[0027] To enhance the warning effect and remind passing vessels to avoid colliding with the bridge pier, a fluorescent strip or indicator light 5-3 is provided on the surface of the connecting buckle 5-1 away from the outer shell 1.

[0028] The working principle of this invention is as follows:

[0029] When the outer shell 1 is impacted, the X-shaped hinge structure 6 provides primary buffering. Simultaneously, due to the deformation of the outer shell 1, the arc-shaped groove at the junction of the two outer shell sections also compresses the rubber pillar 2. The elasticity of the rubber pillar 2 prevents deformation, thus providing secondary buffering. Similarly, when the connecting component 5 is impacted, the arc-shaped groove at the junction of the two outer shell sections is also impacted, compressing the rubber pillar 2. The elasticity of the rubber pillar 2 prevents deformation, thus providing buffering. Simultaneously, the force applied to the rubber pillar 2 can push it outwards away from the arc-shaped buffer block 3, providing reverse damping and making the entire device more secure and less prone to deformation, thus improving the overall stability of the device. Furthermore, the X-shaped hinge structure 6 transmits the force to the arc-shaped buffer block 3, which can be made of elastic material, providing tertiary buffering. Finally, the compression unit 4 on the arc-shaped buffer block 3 provides quaternary buffering. Meanwhile, the deformation of the arc-shaped buffer block 3 can compress the rubber column 2, and the elasticity of the rubber column 2 can prevent deformation, thus achieving buffering. The arc-shaped buffer block 3 adopts a design with multiple compression units 4, which can absorb errors, adapt to bridge piers with uneven thickness, and solve the problem that the protective device cannot fit well with the bridge pier due to construction errors.

[0030] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
