Abstract
Description
Technical Field
[0001] The utility model relates to the field of bridge construction, in particular to the technical field of a rotary barrel type bridge anti-collision device. Background Art
[0002] Bridge anti-collision systems, especially those using steel buckets as buffer devices, have become an important means of protecting bridge structures from damage caused by ship collisions. However, existing steel bucket anti-collision systems have several significant drawbacks and limitations, and are in urgent need of improvement.
[0003] First of all, most traditional steel barrel anti-collision devices adopt a static fixed installation method, which means that when encountering a collision, they can only absorb energy through the deformation of the barrel itself, which often causes serious damage to the barrel or even failure, the repair cost is high, and it cannot effectively reduce the impact force on the main structure of the bridge.
[0004] In addition, the rigid reaction force generated by the fixed steel drum during a ship collision may cause unnecessary damage to the ship, increasing the difficulty of rescue and economic losses after the accident. The damage is particularly severe for small ships. Utility Model Content
[0005] In view of the above problems, the present invention addresses the deficiencies of the existing technology and proposes a rotating barrel bridge anti-collision device, which aims to reduce collision energy and alleviate damage to ships and bridges when a collision occurs.

The guide rail includes an upper guide rail and a lower guide rail spaced apart from each other, and the rotating barrel assembly is arranged between the upper guide rail and the lower guide rail.
[0008] Compared with the existing technology, this case uses a rotating barrel assembly set between the upper guide rail and the lower guide rail set around the base. By utilizing the rotatable feature of the rotating barrel assembly, the direction of the ship can be corrected when a ship collides, and the ship can be restored to the normal navigation track, avoiding impact rebound and protecting the ship and bridge.

[0011] In some embodiments, the first rotating shaft is fixedly connected to the guide rail.
[0012] In some embodiments, the rotary barrel assembly includes a shaft sleeve passing through the gap of the L-shaped track and a rotary barrel with shaft necks at both ends, and the shaft necks are inserted into the shaft sleeve.
[0013] In some embodiments, the rotary barrel assembly includes a shaft sleeve passing through the gap of the L-shaped track, a second rotating shaft inserted into the shaft sleeve, and a rotary barrel inserted into the second rotating shaft and rotatable around the second rotating shaft.
[0014] In some embodiments, the guide rail bracket is provided with a slider that can slide on the guide rail bracket, and the guide rail is connected to the guide rail bracket via the slider.

[0024] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:
[0025] Please refer to Figure 1In the figure, a pier 20 is provided in the middle of the pedestal 10. Therefore, the present invention provides a rotating barrel bridge anti-collision device, which is disposed around the pedestal 10 and specifically includes a guide rail 100 disposed in an annular manner around the pedestal. The guide rail 100 is connected to the pedestal via a guide rail bracket 200. Preferably, guide rails 200 are evenly distributed on each surface of the pedestal 10. For example, in the present embodiment, two guide rail brackets are provided on one surface of the pedestal to ensure uniform force distribution.
[0026] At the same time, a rotatable rotary barrel assembly 300 is provided on the guide rail 100. Figure 2 The guide rail 100 includes an upper guide rail 110 and a lower guide rail 120 spaced apart from each other, and the rotary barrel assembly 300 is disposed between the upper guide rail 110 and the lower guide rail 120. The rotary barrel assembly 300 rotates under the support of the guide rail 100. This feature allows the vessel 1 to be corrected in the event of a collision, restoring it to its normal navigation path and avoiding impact rebound, thereby protecting the vessel 1 and the bridge. For a diagram of this effect, please refer to Figure 7 .
[0027] The operation of the rotary barrel assembly 300 and the guide rail 100 will be described below through a specific embodiment.
[0028] For example 1, please refer to Figure 4 , the guide rail 100 is an L-shaped rail 101 for the backrest, and there will be a gap between the L-shaped rails 101. The rotary barrel assembly 300 passes through the above gap and is installed in the L-shaped rail gap. Specifically, the rotary barrel assembly 300 includes a first rotating shaft 301 passing through the gap between the above-mentioned L-shaped rails 101. Here, the first rotating shaft 301 is fixed to the L-shaped rail 101 by bolt connection. The first rotating shaft 301 is inserted into the rotary barrel 302 that can rotate around the first rotating shaft 301. Here, the rotary barrel 302 is located between the upper guide rail 110 and the lower guide rail 120, which can limit its upper and lower positions, and can also be driven to rotate by water flow.
[0029] The material of the rotary barrel 302 is a composite material with a certain strength and can withstand impact force. In addition, it is also a flexible energy-absorbing material, so it can buffer the impact force. Specifically, a composite material composed of a composite material of EVA (ethylene-vinyl acetate copolymer) and polyurethane can be used. This material combination is very elastic and can effectively absorb impact energy and reduce the impact force during collision. At the same time, it has good wear resistance and can withstand multiple impacts without being easily damaged. At the same time, it has strong restoring power. Even if it suffers a serious impact, the rotary barrel made of this composite material can quickly return to its original shape, maintain its protective function, and reduce the frequency of maintenance and replacement. In addition to excellent mechanical properties, this material also has good weather resistance, can resist the influence of natural environment such as ultraviolet radiation and rain erosion, and extend its service life. In specific applications, the appearance of the rotary barrel 302 can also be designed to be very eye-catching to enhance the visual warning effect.
[0030] In the second embodiment, for the sake of convenience, the same parts as those in the first embodiment are omitted in the second embodiment, mainly the composite material used in the guide rail 100 and the rotating assembly 300. Figure 5 The rotary barrel assembly 300 includes a shaft sleeve 303 that passes through the gap of the L-shaped track 101. This is different from the first embodiment. The shaft sleeve 303 is fixed to the L-shaped track 101 by bolts. In this solution, a rotary barrel 302 with shaft necks 304 at both ends is used to achieve rotation.
[0031] For the sake of convenience, the same parts as those in Example 1 and Example 2 are omitted in Example 3. Figure 6 The rotary barrel assembly 300 includes a shaft sleeve 303 that passes through the gap of the L-shaped track 101. It also includes a second rotating shaft 305 that is sleeved into the shaft sleeve 303. The rotary barrel 302 is sleeved on the second rotating shaft 305 and can rotate around the second rotating shaft 305.
[0032] Example 4, please refer to Figure 6 The above-mentioned buffering is achieved by the rotary barrel assembly 300. To further enhance the buffering effect of the integrated rotary barrel bridge anti-collision device, in some embodiments, a slider 210 is provided on the guide rail bracket 200. The slider 210 can slide on the guide rail bracket 200, and the guide rail 100 is connected to the guide rail bracket 200 via the slider 210. In this way, when an impact is received, the entire guide rail 100 can also have a buffering effect, and subsequent repair is also facilitated.
[0033] As mentioned above, this case protects a rotary barrel bridge anti-collision device, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
