Description

Technical Field

[0001] This utility model relates to the field of bridge pier maintenance technology, specifically a protective device for bridge pier maintenance. Background Technology

[0002] Bridge piers are crucial components of a bridge structure, supporting and stabilizing the entire structure. They are typically located above water or below ground level, playing a vital role in bearing the load of the bridge's superstructure. The primary function of bridge piers is to transfer the load from the bridge's superstructure to the foundation, ensuring the bridge's stability and safety.

[0003] However, in existing technologies, protective devices for bridge pier maintenance are typically installed around the pier to protect it. But when subjected to strong water flow, floating debris such as gravel and garbage may directly impact the protective device, causing wear or cracking of the pier surface. Furthermore, small objects or weeds may enter between the protective device and the pier, causing blockages. Consequently, when maintenance is needed later, the blocked protective device and the cumbersome disassembly and reassembly process may waste workers' time and energy, reducing work efficiency. Therefore, we provide a protective device for bridge pier maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for bridge pier maintenance to solve the problems mentioned in the background art.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a protective device for bridge pier maintenance includes: a protective mechanism 1, which includes a lower pier body 11. A first protective ring 12 is provided on one side of the top of the lower pier body 11, and an upper pier body 31 is provided on the top of the lower pier body 11. The first protective ring 12 and a second protective ring 13 are nested outside the upper pier body 31. A second protective ring 13 is provided on the other side of the top of the lower pier body 11. Slots 14 are provided at both ends of the first protective ring 12 near the second protective ring 13, and positioning grooves 15 are provided on one side of each slot 14. Inserts 16 are provided at both ends of the second protective ring 13 near the first protective ring 12, and positioning blocks 17 are provided on the side of each insert 16 away from the second protective ring 13. Both ends of one side of the protective ring 12 are fixedly connected to the insert block 16, and one side of the insert block 16 is fixedly connected to the positioning block 17. Two sealing grooves 19 are opened on both sides of the first protective ring 12. The outside of the insert block 16 is inserted into the slot 14, the outside of the positioning block 17 is mated with the inside of the positioning groove 15, and the outside of the sealing ring 110 is mated with the inside of the sealing groove 19. A sealing ring 110 is provided inside each of the four sealing grooves 19, and a bolt 111 is provided inside each of the four sealing grooves 19. One end of the bolt 111 passes through the sealing groove 19 and the inner ring of the sealing ring 110 and is threadedly connected to the inner wall of the threaded groove opened in the insert block 16. A guide groove 18 is opened on the outside of the first protective ring 12 and the second protective ring 13. An auxiliary mechanism 2 is provided at both ends of the first protective ring 12 and the second protective ring 13.

[0024] In this embodiment, when workers need to maintain the bridge pier, they need to disassemble and assemble the protective device. Therefore, workers can remove the bolts 111 from the sealing groove 19, and then the insert block 16 will be released from the fixed limit in the slot 14. Workers can then remove the first protective ring 12 and the second protective ring 13 and maintain the bridge pier. Workers can use the positioning groove 15 and the positioning block 17 to achieve the initial positioning and fixing of the first protective ring 12 and the second protective ring 13 during installation, ensuring that the bolts 111 can be smoothly installed in the threaded grooves opened between them. By setting the sealing groove 19 and the sealing ring 110, mud and sand impurities can be prevented from entering the threaded grooves opened between them, avoiding the problem of blockage, saving workers time and effort in disassembling and assembling the protective device, and improving work efficiency.

[0025] like Figures 1-4 As shown, the auxiliary mechanism 2 includes a protective plate 21. Two buffer grooves 24 are opened at both ends of the first protective ring 12 and the second protective ring 13. The inner wall of the buffer groove 24 is slidably connected to the outside of the buffer rod 22. The end of the buffer rod 22 away from the buffer groove 24 passes through the inner ring of the buffer spring 23 and is fixedly connected to one side of the protective plate 21. The side of the protective plate 21 close to the buffer rod 22 is fixedly connected to one end of the buffer spring 23.

[0026] In this embodiment, when the gravel and debris in the river are about to hit the protective device, they will first come into contact with the protective plate 21, which will generate pressure. This will push the pressure plate to move toward the protective device. The buffer spring 23 will be compressed and deformed by the pressure plate during its movement, and the buffer rod 22 will be recessed into the buffer groove 24. Therefore, the impact force generated by the river and the impacting object can be mitigated, preventing damage to the first protective ring 12, the second protective ring 13, and the bridge pier.

[0027] This utility model provides a protective device for bridge pier maintenance, the specific working principle of which is as follows:

[0028] When maintenance personnel inspect or repair the bridge piers, the first step is to remove the bolts 111 from the sealing groove 19. These bolts 111 are key components used to secure the first protective ring 12 and the second protective ring 13. By removing the bolts 111, the insert block 16 will be released from its fixed position within the slot 14, allowing the personnel to easily remove the first protective ring 12 and the second protective ring 13, thus facilitating bridge pier maintenance. When installing new protective devices, the personnel can use the positioning groove 15 and the positioning block 17 to achieve initial positioning and fixation. This ensures that the bolts 111 can be smoothly installed in the threaded grooves between them, thereby guaranteeing the stability and reliability of the entire protective device. In addition, when the debris in the river is about to hit the protective device, it will first come into contact with the protective plate 21, which will generate pressure and push the pressure plate towards the protective device. During this process, the buffer spring 23 will be compressed and deformed by the pressure plate moving. At the same time, the buffer rod 22 will also be recessed into the buffer groove 24, which can mitigate the impact force generated by the river and the impacting object, thereby protecting the pier from damage.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
