Description

Technical Field

[0001] This utility model relates to the field of bridge pile foundation protection technology, specifically a bridge pile foundation protection device. Background Technology

[0002] In bridge pile foundation protection, pile body impact and shock absorption protection is an important measure, mainly used to prevent damage to the pile body from impacts by ships, floating objects, vehicles or other external forces, while reducing the impact of dynamic loads such as earthquakes and waves on the pile foundation.

[0003] Currently, most bridge pile foundations have inflatable plastic shells or airbags installed on their surfaces to reduce damage caused by accidental collisions between passing vessels and the pile foundations. However, with a single airbag, the airbag only uses compressed air to buffer the impact during a collision and cannot actively adjust the damping. It cannot effectively absorb high-speed, high-mass impacts. Moreover, when the airbag rebounds, it may push the vessel in the opposite direction, causing a secondary collision. Furthermore, existing protective airbags are generally fixed. Fixed airbags only buffer the impact perpendicular to the pile body and cannot guide the vessel to slide tangentially. The remaining kinetic energy still acts on the pile foundation. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge pile foundation protection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge pile foundation protection device, comprising a pile foundation body, and further comprising:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, a bridge pile foundation protection device includes a pile foundation body 1, and further includes:

[0023] Mounting rings 2 are snapped onto both sides of the surface of the pile foundation 1. Mounting plates 3 are fixedly connected to the top and bottom of the two mounting rings 2. The two mounting plates 3 are fixed together by screws. Two T-shaped tracks 4 are opened inside the two mounting rings 2.

[0024] An extension post 5 is installed on one side of the mounting ring 2. A fixing plate 6 is fixedly connected to one side of the extension post 5. A buffer assembly 7 is fixedly connected to one side of the fixing plate 6. The buffer assembly 7 includes a positioning plate 701. A protective ring 8 is provided on one side of the mounting ring 2. An extension frame 9 is fixedly connected to one side of the fixing plate 6. The mounting ring 2 and the mounting plate 3 can be used to fix them to the surface of the pile foundation 1 with screws. The T-shaped rail 4 facilitates the circumferential movement of multiple protective rings 8. The extension post 5 facilitates the fixing of the fixing plate 6. The fixing plate 6 facilitates the fixed installation of the buffer assembly 7. The buffer assembly 7 is located between the protective ring 8 and the fixing plate 6, which can play a buffering role and reduce the impact force of the ship on the pile foundation 1.

[0025] A T-shaped slider 10 is fixedly connected between one side of the two extension columns 5. The surface of the T-shaped slider 10 is slidably connected to the inside of the T-shaped track 4. A reinforcing block 11 is fixedly connected to one side of the extension column 5. One side of the reinforcing block 11 is fixedly connected to the fixing plate 6. Two airbag strips 16 are fixedly connected to one side of the protective ring 8. Through the fixing of the extension column 5 and the T-shaped slider 10, and the sliding of the T-shaped slider 10 with the inside of the T-shaped track 4, when the protective ring 8 is under force, it will cooperate with the buffer component 7, the fixing plate 6 and the extension column 5 to make the T-shaped slider 10 move in a ring along the inside of the T-shaped track 4, thereby unloading the colliding ship and preventing the ship from colliding with the pile foundation 1 again. At the same time, it also reduces the strength of protection by relying solely on the buffer component 7.

[0026] Two dampers 12 are fixedly connected to one side of the fixed plate 6. The side of the damper 12 closest to the protective ring 8 is hinged to the protective ring 8. A buzzer alarm 13 is fixedly connected to one side of the protective ring 8, and a pressure sensor 14 electrically connected to the buzzer alarm 13 is also fixedly connected to one side of the protective ring 8. A pressure-absorbing column 15 is fixedly connected to one side of the extension frame 9. It is fixed between the fixed plate 6 and the protective ring 8 by the dampers 12, which can assist in absorbing the pressure of the collision. When the protective ring 8 is subjected to an external collision and undergoes compression deformation, its displacement reaches a preset threshold, and then... The pressure sensor 14, fixed on one side of the protective ring 8, will come into contact with and be squeezed by the pressure column 15 on the extension frame 9. At this time, the pressure sensor 14 is triggered, and a high-decibel alarm signal is immediately emitted through the buzzer alarm 13 electrically connected to it. This linkage alarm system can monitor the occurrence of collision events in real time, effectively warning passing ships to avoid the collision in time, and reminding on-site personnel to take emergency measures, thereby significantly improving the safety early warning capability of the pile foundation protection system. This is existing technology, which is clearly known to those skilled in the art, and will not be described in detail here.

[0027] Two positioning plates 701 are fixed to the front and rear sides of one side of the fixed plate 6. A limiting rod 702 is fixedly connected between the two positioning plates 701. Slide plates 703 are slidably connected to both sides of the surface of the limiting rod 702. A guide plate 704 is hinged to one side of the slide plate 703. The end of the guide plate 704 away from the slide plate 703 is hinged to the protective ring 8. A high-pressure spring 705 is fixedly connected between the slide plate 703 and one side of the positioning plate 701. When the protective ring 8 is subjected to external impact, the pressure will move through the two guide plates 704 and drive the slide plate 703 to move to both sides on the limiting rod 702 and compress the high-pressure spring 705, thereby buffering the impact pressure.

[0028] Working principle: First, the mounting ring 2, along with the mounting plate 3 and bolts, is fixed to the surface of the pile foundation 1. Then, through the setting of four protective rings 8 and buffer components 7, the surface of the pile foundation 1 can be fully protected. At the same time, with the setting of T-shaped sliders 10 and T-shaped rails 4, the kinetic energy generated by the collision can be dissipated and the ship can be guided to the navigation direction. When the protective ring 8 is subjected to external collision, the pressure will move through the two guide plates 704 and drive the sliding plate 703 on the limit rod 702 to move to both sides and compress the high-pressure spring 705, thereby buffering the collision pressure. In addition, the resistance on both sides... The damper 12 can help buffer the pressure of the collision. When the protective ring 8 is subjected to an external collision and undergoes compression deformation, its displacement reaches a preset threshold. At this time, the pressure sensor 14 fixed on one side of the protective ring 8 will come into contact with the pressure column 15 on the extension frame 9 and be squeezed. At this time, the pressure sensor 14 is triggered and a high-decibel alarm signal is immediately issued through the buzzer alarm 13 electrically connected to it. This linkage alarm system can monitor the occurrence of the collision event in real time, which can effectively warn the surrounding passing ships to avoid it in time, and remind the on-site staff to take emergency measures, thereby significantly improving the safety early warning capability of the pile foundation protection system.
