Description

Technical Field

[0001] This utility model relates to the field of anti-collision structure technology, and in particular to an assembled bridge anti-collision structure. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures erected to cross mountains, overcome adverse geological conditions, or meet other transportation needs, making passage more convenient. Bridge railings are guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going off the bridge, preventing vehicles from breaking through, passing under, or overturning the bridge, and also enhancing the aesthetics of the bridge structure. Announcement No. CN218466341U discloses a prefabricated steel column anti-collision guardrail structure for bridges, including a steel column body. The outer wall of the steel column body is movably connected to a first fixing sleeve and a second fixing sleeve. The first fixing sleeve is located on top of the second fixing sleeve, and both ends of the first fixing sleeve are fixedly connected to the second fixing sleeve. The inner walls of the two second fixing sleeves are connected by bolts and threads. A locking block is fixedly connected to the front of the first fixing sleeve, and a fixing plate is provided on the front of the locking block. This invention utilizes a combination of a first fixing sleeve, a second fixing sleeve, a locking block, an auxiliary groove, a tension spring, compression pads, a fixing plate, and a locking groove. First, four compression pads are placed inside the auxiliary groove. Then, the locking block engages with the inner wall of the locking groove, causing the compression pads to move into the groove. Due to the elasticity of the tension spring, the compression pads press against the inner wall of the locking groove, achieving a stable installation. However, in practice, the fixing relationship between the locking block and the fixing plate relies on the friction generated by the spring force pushing the compression block against the inner wall of the locking groove on the fixing plate. While this method allows for later disassembly, repair, and replacement of the protective pad, the fixation between the locking block and the fixing plate is not secure and there is still a risk of detachment, which could affect the normal use of the protective pad. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a prefabricated bridge anti-collision structure, including a column, a first fixing sleeve and a second fixing sleeve are fitted on the surface of the column, the first fixing sleeve and the second fixing sleeve are fixedly connected, a fixing seat is fixedly connected to the surface of the first fixing sleeve, an anti-collision mechanism is fixedly connected inside the fixing seat, the anti-collision mechanism includes a block, a fixing plate is fixedly connected to the surface of the block, a buffer is fixedly connected to the surface of the fixing plate, a protective plate is fixedly connected to one end of the buffer, a rubber pad is provided on the surface of the protective plate, a round hole and an insertion hole are opened on the surface of the fixing seat and the block, a pin is inserted into the round hole and the insertion hole, a slot is opened on the surface of the pin, a pull rod is fixedly connected to one end of the pin, and a fixing component is fixedly connected to the surface of the fixing seat.

[0005] Preferably, the fixing component includes a fixing block, an insert rod slidably connected inside the fixing block, a connecting rod fixedly connected to the surface of the insert rod, a handle fixedly connected to one end of the connecting rod, a spring sleeved on the surface of the connecting rod, and the insert rod inserted into the interior of the slot. This facilitates the fixing of the pin.

[0006] Preferably, a magnet is fixedly connected inside the slot, and the magnet is magnetically connected to the insertion rod. Here, the magnetic attraction between the magnet and the insertion rod further improves the stability of the insertion rod in fixing the pin.

[0007] Preferably, the surface of the handle is fixedly connected with anti-slip ridges, which are evenly distributed on the surface of the handle. This increases the friction when gripping the handle and prevents slippage.

[0008] Preferably, a limiting rod is fixedly connected to the arc surface of the first fixing sleeve, and a limiting hole is formed on the surface of the column, with the limiting rod inserted into the limiting hole. This design limits the movement of the first fixing sleeve, preventing it from rotating after being installed on the column.

[0009] Preferably, the surfaces of the circular hole and the insertion hole are provided with a first guide groove and a second guide groove, and a guide rod is fixedly connected to the surface of the pin, the guide rod being engaged inside the first guide groove and the second guide groove. This design guides and limits the pin inserted into the circular hole and the insertion hole, preventing the rod from rotating during insertion, allowing the slot on the pin to quickly align with the rod, further improving the convenience of fixing the pin.

[0010] Preferably, the arc surface of the protective plate is provided with a T-slot, and a T-shaped rod is fixedly connected to the surface of the rubber pad, with the T-shaped rod slidably connected inside the T-slot. This allows for the replacement of aged or damaged rubber pads, ensuring the anti-collision structure maintains good performance and preventing the entire anti-collision system from failing due to deteriorating rubber pad performance. This reduces the need for large-scale repairs and replacements due to damage to the anti-collision structure, lowering the long-term maintenance costs of the bridge.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a structure of pin, fixing block, insert rod, spring, connecting rod and handle, allows for the installation of the anti-collision mechanism. The square block on the fixing plate is inserted into the fixing seat, followed by the pin being inserted into the round hole and the insertion hole. Then, the handle is pulled. Once the pin is fully inserted into the round hole, the handle is released. Under the action of the spring, the insert rod pushes the connecting rod and the insertion rod to slide inside the fixing block, ultimately inserting the insertion rod into the insertion hole on the pin. This achieves the installation of the fixing plate and facilitates the disassembly of the anti-collision mechanism. The disassembly steps are simple and efficient, improving the efficiency and convenience of replacing damaged anti-collision mechanisms later.

[0013] 2. By setting T-shaped rods and T-shaped grooves, when the rubber pad is damaged, it can be removed from the protective plate and a new rubber pad can be installed on the protective plate. The T-shaped rods on the rubber pads are inserted into the T-shaped grooves on the protective plate, which enables the replacement of aged and damaged rubber pads. This ensures that the performance of the anti-collision structure is always in good condition, avoids the failure of the entire anti-collision system due to the deterioration of the rubber pad performance, thereby reducing the large-scale repair and replacement work required due to damage to the anti-collision structure and reducing the long-term maintenance cost of the bridge.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-5This utility model provides a technical solution: a prefabricated bridge anti-collision structure, including a column 1, with a first fixing sleeve 2 and a second fixing sleeve 3 fitted on the surface of the column 1, the first fixing sleeve 2 and the second fixing sleeve 3 being fixedly connected. A fixing seat 4 is fixedly connected to the surface of the first fixing sleeve 2, and an anti-collision mechanism is fixedly connected inside the fixing seat 4. The anti-collision mechanism includes a block 5, a fixing plate 6 is fixedly connected to the surface of the block 5, a buffer 7 is fixedly connected to the surface of the fixing plate 6, a protective plate 8 is fixedly connected to one end of the buffer 7, and a rubber pad 9 is provided on the surface of the protective plate 8. The surfaces of the fixing seat 4 and the block 5 have round holes 12 and insertion holes 14, and pins 16 are inserted into the round holes 12 and insertion holes 14. The surface of the pins 16 has slots 18, and a pull rod 17 is fixedly connected to one end of the pins 16. A fixing component is fixedly connected to the surface of the fixing seat 4, and the fixing component includes a fixing block 21. A rod 22 is slidably connected inside the fixing block 21. A connecting rod 23 is fixedly connected to the surface, and a handle 24 is fixedly connected to one end of the connecting rod 23. A spring 28 is sleeved on the surface of the connecting rod 23. The insertion rod 22 is inserted into the slot 18, which facilitates the fixing of the pin 16. A magnet 19 is fixedly connected inside the slot 18, and the magnet 19 is magnetically connected to the insertion rod 22. The magnetic attraction between the magnet 19 and the insertion rod 22 further improves the stability of the insertion rod 22 in fixing the pin 16. Anti-slip ridges 25 are fixedly connected to the surface of the handle 24. The anti-slip ridges 25 are evenly distributed on the surface of the handle 24, which can increase the friction when gripping the handle 24 and prevent slippage. A limiting rod 11 is fixedly connected to the arc surface of the first fixing sleeve 2. A limiting hole 10 is opened on the surface of the column 1, and the limiting rod 11 is inserted into the limiting hole 10. This can limit the first fixing sleeve 2 and prevent the first fixing sleeve 2 from rotating after it is installed on the column 1.

[0025] Example 2

[0026] Please see Figure 2-4The surfaces of the round hole 12 and the insertion hole 14 are provided with a first guide groove 13 and a second guide groove 15. A guide rod 20 is fixedly connected to the surface of the pin 16. The guide rod 20 is locked inside the first guide groove 13 and the second guide groove 15. This can guide and limit the pin 16 inserted into the round hole 12 and the insertion hole 14, preventing the insertion rod 22 from rotating when inserted. This allows the slot 18 on the pin 16 to quickly align with the insertion rod 22, further improving the convenience of fixing the pin 16. The arc surface of the protective plate 8 is provided with a T-shaped groove 26. A T-shaped rod 27 is fixedly connected to the surface of the rubber pad 9. The T-shaped rod 27 is slidably connected inside the T-shaped groove 26. This allows for the replacement of aged and damaged rubber pads 9, ensuring that the performance of the anti-collision structure is always in good condition. This avoids the failure of the entire anti-collision system due to the deterioration of the performance of the rubber pad 9, thereby reducing the large-scale repair and replacement work required due to damage to the anti-collision structure and reducing the long-term maintenance cost of the bridge.

[0027] Working principle: During use, when installing this anti-collision structure, firstly, the first fixing sleeve 2 is clamped onto the surface of the column 1. With the precise cooperation of the limiting rod 11 and the upper limit hole 10 of the column 1, the first fixing sleeve 2 is accurately positioned and secured, preventing axial displacement. Then, the second fixing sleeve 3 is fitted on, and bolts are used to fix the second fixing sleeve 3 to the first fixing sleeve 2. When installing the anti-collision mechanism, the square block 5 on the fixing plate 6 is inserted into the interior of the fixing seat 4. Then, the pull rod 17 is held, and the pin 16 is inserted into the round hole 12 and the insertion hole 14. Pulling handle 24, once the pin 16 is fully inserted into the round hole 12, the pin 16 is prevented from rotating by the cooperation of guide rod 20, first guide groove 13, and second guide groove 15, allowing the slot 18 on the pin 16 to quickly align with the rod 22. Then, releasing handle 24 allows the rod 22 to slide within the fixing block 21 under the action of spring 28, pushing connecting rod 23 and the rod 22 together. Finally, the rod 22 inserts into the insertion hole 14 on the pin 16 and attracts the magnet 19 inside the insertion hole 14, thus securing the fixing plate 6. The installation is convenient and easy to disassemble. The disassembly process is simple and efficient, which improves the efficiency and convenience of replacing damaged anti-collision mechanisms later. When a vehicle accidentally hits the protective plate 8, the impact force first acts on the rubber pad 9. The rubber pad 9 uses its own elastic deformation to buffer part of the energy and reduce the impact force. The remaining impact energy is transmitted to the protective plate 8. The protective plate 8 uses the expansion and contraction and damping characteristics of the buffer 7 to further absorb and dissipate the energy, greatly reducing the impact force transmitted to the column 1 and the main structure of the bridge, and protecting the bridge from serious damage in all aspects. When the rubber pad 9 is damaged, the rubber pad 9 is removed from the protective plate 8, and then a new rubber pad 9 is installed on the protective plate 8. The T-shaped rod 27 on the rubber pad 9 is inserted into the T-shaped groove 26 on the protective plate 8, which realizes the replacement of aged and damaged rubber pads 9. This ensures that the performance of the anti-collision structure is always in good condition and avoids the failure of the entire anti-collision system due to the deterioration of the performance of the rubber pad 9. This reduces the large-scale repair and replacement work required due to damage to the anti-collision structure and reduces the long-term maintenance cost of the bridge.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
