Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bridge pier protection, and in particular to a waterway bridge pier protection structure. Background Art
[0002] Since ships pass by port and navigation piers frequently, in order to avoid damage to the piers caused by collisions between ships and piers and to ensure the safety of the bridge, protective structures are usually installed on the outside of port and navigation piers. At the same time, in most cases, the collisions are directly on the upstream or downstream side of the piers. Therefore, the research on anti-collision protection devices of piers is very important. There are many types of existing anti-collision protection devices for piers, with various structures and materials.
[0003] After years of research and application, bridge pier protection has evolved from artificial islands constructed of stone blocks to flexible crash blocks that use deformed materials like rubber to dissipate energy, as well as floating or fixed crash boxes. These systems rely on the use of attached structures for isolation, energy absorption, and momentum buffering. Crash boxes or blocks, among other components, are the most widely used bridge pier protection devices due to their moderate cost, high protection, and ease of manufacture and installation.
[0004] At present, the protective structures of many port and shipping piers adopt fixed anti-collision blocks or anti-collision plates. The anti-collision plates are large in size and difficult to install. At the same time, the fixed structure means that they can only buffer and dissipate energy through their own performance, and their specific strength requirements are high. Therefore, the inventor believes that a waterway pier protection structure that is easy to install and has good buffering and energy dissipation effects should be designed. Utility Model Content

[0029] Reference Figures 1 to 4 The first protection unit 2 includes a fixing frame 201 and an elastic member 202 provided on the fixing frame 201. The fixing frame 201 is rotatably connected to the bridge pier 1. The sides of adjacent elastic members 202 can be connected. A connecting member 4 is provided on the side of the first protection unit 2, and the connecting member 4 connects multiple first protection units 2. Specifically, the fixing frame 201 is a triangular frame structure. The fixing frame 201 includes a vertical rod 201a and horizontal rods 201b provided at the upper and lower ends of the vertical rod 201a. The horizontal rod 201b is an L-shaped rod. The vertical rod 201a is located at the bend of the horizontal rod 201b. The two ends of the horizontal rod 201b are connected to the two sides of the elastic member 202.
[0030] The elastic member 202 is an O-shaped cylindrical structure made of rubber material. One side of the elastic member 202 is flat and connected to the fixing frame 201. Hollow cylinders are provided on both sides of the elastic member 202. The end of the horizontal rod 201b is provided with a bent section and the bent section can be inserted into the hollow cylinder. A connecting rod 201c is vertically provided at the end of the fixing frame 201. A mounting sleeve 5 is provided on the connecting rod 201c. One end of the mounting sleeve 5 is sleeved with the upper end of the connecting rod 201c, and the other end of the mounting sleeve 5 is threadedly connected to the first embedded part 101. In this embodiment, The connecting rod 201c is located at the end of the longer horizontal rod 201b and is set away from the vertical rod 201a.

At the same time, an elastic member 202 is set on the fixing frame 201 and adjacent elastic members 202 can be connected. During the rotation of the first protection unit 2, the impact is transmitted through the elastic member 202, which has a good buffering effect, ensuring the stability of the pier and good protection effect. At the same time, since the first protection unit 201 can rotate, it can play a side guiding effect on the colliding bow by rotation when a collision occurs, thereby reducing the impact. The second protection unit 3 can ensure the side anti-collision effect of the pier 1, and combined with the first protection unit 2, it can ensure the integrity of the pier 1.
