Description

Technical Field

[0001] This utility model belongs to the field of bridge pier protection technology, specifically relating to a bridge pier protection structure. Background Technology

[0002] In the field of bridge engineering, bridge piers, as key components supporting the superstructure of bridges, are exposed to the natural environment and complex traffic conditions for extended periods, facing numerous potential threats. Among these, ship collisions are one of the most severe and destructive external forces that bridge piers may encounter. Once a collision occurs, it will not only directly damage the pier structure and affect the stability and safety of the bridge, but may also trigger a chain reaction, leading to damage to the overall function of the bridge and even causing serious traffic accidents and economic losses.

[0003] However, most existing bridge pier protection structures employ only a single protection method, such as relying solely on rigid protective plates to withstand ship impacts. Such structures cannot effectively disperse and buffer impact forces upon impact; rigid contact leads to concentrated impact forces acting on a localized area of ​​the pier, easily causing severe local damage and even structural fracture. Furthermore, when rigid protective plates collide directly with ships, they can also cause significant damage to the ship's structure, increasing the severity of the accident. Therefore, this applicant proposes a bridge pier protection structure to address the aforementioned problems. Utility Model Content

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

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bridge pier protection structure, comprising:

[0007] The bridge pier column has arc-shaped plates on both outer sides, and arc-shaped anti-collision plates are provided on the outer sides of the two arc-shaped plates. The outer arc surfaces of the two arc-shaped anti-collision plates are provided with anti-collision grooves in a ring array, and the anti-collision grooves are arc-shaped.

[0008] Each of the two arc-shaped anti-collision plates is provided with an anti-collision mechanism outside the two arc-shaped anti-collision plates and within multiple anti-collision grooves. Multiple buffer mechanisms are arranged in a circular array on the inner arc surface of the two arc-shaped anti-collision plates and the outer arc surface of the two arc-shaped plates.

[0009] One of the arc-shaped anti-collision plates has two sets of locking blocks fixedly installed on both sides of its vertically oriented sidewalls, with two locking blocks in each set. The other arc-shaped anti-collision plate has a positioning mechanism connected to the adjacent locking block on each of its top two sides.

[0010] Both sides of the two arc-shaped anti-collision plates are fixedly equipped with protective nets, and multiple connecting rods are fixedly installed at the bottom of the two protective nets. Both sides of the lower outer end of the bridge pier column are provided with floating plates, and the top of the two floating plates is fixedly installed with the bottom of the multiple connecting rods.

[0011] Preferably, the other arc-shaped anti-collision plate has slots on both side walls, and the slots engage with the card blocks. The other arc-shaped anti-collision plate has insertion holes on both sides of its top, and the tops of both card blocks have slots that match the insertion holes.

[0012] Preferably, the positioning mechanism includes a connecting plate disposed on top of another arc-shaped anti-collision plate. The connecting plate is inverted U-shaped, and the bottom ends of both ends of the connecting plate are fixedly installed with the top of the adjacent arc-shaped anti-collision plate. A pull rod is provided inside the connecting plate. The bottom end of the pull rod is inserted into a slot through a hole. A pull block is fixedly installed through the top of the connecting plate at the top of the pull rod. A spring is sleeved on the outside of the pull rod. The two ends of the spring are fixedly connected to the bottom of the pull block and the top of the connecting plate, respectively.

[0013] Preferably, the anti-collision mechanism includes two mounting plates arranged vertically and symmetrically in the anti-collision groove. One side of each of the two mounting plates is fixedly installed to the inner arc surface of the anti-collision groove. A rotating rod is fixedly installed on the adjacent sidewall of each of the two mounting plates. The adjacent ends of the two rotating rods are rotatably connected to an anti-collision roller. Multiple anti-collision protrusions are fixedly installed in a ring array on the outside of the anti-collision roller.

[0014] Preferably, the buffer mechanism includes a sleeve disposed on the outer arc surface of the arc-shaped plate. The end of the sleeve near the arc-shaped anti-collision plate is open, and the other end of the sleeve is fixedly installed on the outer arc surface of the arc-shaped plate. A limit frame is fixedly installed on the inner ring wall of the sleeve at the opening. A second spring is provided inside the sleeve. One end of the second spring is fixedly connected to the inner wall of one side of the sleeve, and the other end of the second spring is fixedly connected to the limit plate. A support rod is fixedly installed on the side of the limit plate away from the second spring, and the end of the support rod away from the limit plate is fixedly installed on the inner arc surface of the arc-shaped anti-collision plate.

[0015] Preferably, fixing plates are fixedly installed on both sides of the two floating plates, and threaded holes are opened on one side of the multiple fixing plates, and the two adjacent fixing plates are connected by bolt threads on one side.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The positioning mechanism improves the ease of installation of the protective structure. By holding the pull block and pulling it upward, the bottom end of the pull rod is separated from the slot. Then, the two arc-shaped anti-collision plates are brought close together so that the pull block and the slot are engaged. After releasing the pull block, the elastic restoring force of the spring automatically pulls the pull rod back into the slot to complete the fixation. This process does not require the use of bolts or other fasteners, which greatly reduces the burden of personnel installation and operation. At the same time, it ensures that the two arc-shaped anti-collision plates are accurately aligned and joined together, effectively wrapping the outside of the bridge pier column, improving installation efficiency and practicality.

[0018] (2) The buffer mechanism and the anti-collision mechanism work together to improve the buffering effect. The synergistic effect of the anti-collision mechanism and the buffer mechanism forms a double protection, which improves the impact resistance of the bridge pier. The anti-collision mechanism converts the vertical impact force into rolling friction through the rolling of the anti-collision roller, and disperses the stress with the anti-collision protrusion to reduce local damage. The buffer mechanism further absorbs the remaining impact force through the elastic deformation of the spring, and converts the instantaneous impact into a gradual buffer. The two work together to first reduce the collision friction through rolling, and then reduce the impact force through elastic shock absorption, effectively protecting the bridge pier column from direct impact, while reducing the damage to the ship structure, and realizing two-way protection for the bridge pier and the ship.

[0029] Example 1:

[0030] Please see Figures 1-6 As shown, a bridge pier protection structure includes: a bridge pier column 5, with arc-shaped plates 6 on both outer sides of the bridge pier column 5, and arc-shaped anti-collision plates 4 on the outer sides of the two arc-shaped plates 6. The outer arc surfaces of the two arc-shaped anti-collision plates 4 are provided with anti-collision grooves in a ring array, and the anti-collision grooves are arc-shaped.

[0031] Two arc-shaped anti-collision plates 4 are respectively provided with an anti-collision mechanism 3 outside and located in multiple anti-collision grooves. Multiple buffer mechanisms 2 are arranged in a ring array on the inner arc surface of the two arc-shaped anti-collision plates 4 and the outer arc surface of the two arc-shaped plates 6.

[0032] Two sets of locking blocks 11 are fixedly installed on both ends of one of the arc-shaped anti-collision plates 4 in a vertical state, and there are two locking blocks 11 in each set. On the top two sides of the other arc-shaped anti-collision plate 4, a positioning mechanism 1 connected to the adjacent locking block 11 is respectively provided.

[0033] Both sides of the two curved anti-collision plates 4 are fixedly equipped with protective nets 8, and multiple connecting rods 9 are fixedly installed at the bottom of the two protective nets 8. Both sides of the lower outer end of the bridge pier column 5 are equipped with floating plates 7, and the top of the two floating plates 7 is fixedly installed with the bottom of the multiple connecting rods 9.

[0034] As can be seen from the above, the anti-collision mechanism 3 can protect the bridge pier 5 from direct impact, and the rolling buffer reduces damage to the hull structure. The positioning mechanism 1 can fit and fix the two arc-shaped anti-collision plates 4 and 6 to the outside of the bridge pier 5. The protective net 8 can block debris such as garbage and branches floating on the water surface to prevent the debris from affecting the protective structure. The floating plate 7 can make the entire protective structure float on the water surface and can stably fit and protect the bridge pier 5. Through the cooperation of the above multiple mechanisms, the protective effect on the bridge pier can be effectively improved, and its practicality can be enhanced.

[0035] For details, please refer to Figure 3 As shown, the other arc-shaped anti-collision plate 4 has slots on both sides of its end walls, and the slots are engaged with the card blocks 11. The other arc-shaped anti-collision plate 4 has insertion holes on both sides of its top, and the tops of the two card blocks 11 have slots that are compatible with the insertion holes.

[0036] As can be seen from the above, by setting the insertion hole and slot, when the card block 11 is engaged with the card slot, the insertion hole and slot are matched, which facilitates the fixing of the two arc-shaped anti-collision plates 4 by the pull rod 102 in the positioning mechanism 1.

[0037] For details, please refer to Figure 4 As shown, the positioning mechanism 1 includes a connecting plate 101 disposed on the top of another arc-shaped anti-collision plate 4. The connecting plate 101 is inverted U-shaped, and the bottom ends of the connecting plate 101 are fixedly installed with the top of the adjacent arc-shaped anti-collision plate 4. A pull rod 102 is provided inside the connecting plate 101. The bottom end of the pull rod 102 is inserted into the slot through the insertion hole. The top end of the pull rod 102 passes through the top of the connecting plate 101 and is fixedly installed with a pull block 103. A spring 104 is sleeved on the outside of the pull rod 102. The two ends of the spring 104 are fixedly connected to the bottom of the pull block 103 and the top of the connecting plate 101, respectively.

[0038] As can be seen from the above, by setting the spring 104, the personnel can pull the pull block 103 upwards, and at the same time the pull block 103 stretches the spring 104 upwards, causing the bottom end of the pull rod 102 to separate from the slot. Then, the two arc-shaped anti-collision plates 4 are brought closer together, so that multiple blocks 11 are engaged with the slot. Then, the personnel release the pull block 103, causing the spring 104 to lose tension and elastically recover, pulling the pull block 103 to drive the pull rod 102 back into the slot, thereby achieving the fixation between the two arc-shaped anti-collision plates 4. At the same time, the two arc-shaped plates 6 are aligned and brought together, which can effectively wrap the outside of the bridge pier column 5. There is no need for personnel to use bolts or other fasteners to install the protective structure, reducing the burden of personnel operation and improving its practicality.

[0039] For details, please refer to Figure 5 As shown, the anti-collision mechanism 3 includes two vertically symmetrical mounting plates 301 arranged in the anti-collision groove. One side of each mounting plate 301 is fixedly installed to the inner arc surface of the anti-collision groove. A rotating rod 302 is fixedly installed on the adjacent side wall of each mounting plate 301. The adjacent ends of the two rotating rods 302 are rotatably connected to an anti-collision roller 303. Multiple anti-collision protrusions 304 are fixedly installed in a ring array on the outside of the anti-collision roller 303.

[0040] As can be seen from the above, by setting up the anti-collision roller 303 and the rotating rod 302, when the ship collides with the bridge pier column 5, the ship hull first contacts the anti-collision roller 303. The anti-collision roller 303 can rotate freely in the horizontal direction through the rotating rod 302, converting the vertical impact force into rolling friction, which greatly reduces the peak impact force at the moment of collision. The ring array of anti-collision protrusions 304, through the irregular contact surface design, disperses the concentrated stress into components in multiple directions, avoiding structural damage caused by local stress concentration. This mechanism not only protects the bridge pier column 5 from direct impact, but also reduces the damage to the ship structure through rolling buffer, realizing two-way protection for the bridge pier and the ship, and significantly improving the safety performance of water traffic facilities.

[0041] refer to Figure 6 As shown, the buffer mechanism 2 includes a sleeve 201 disposed on the outer arc surface of the arc plate 6. The end of the sleeve 201 near the arc-shaped anti-collision plate 4 is open, and the other end of the sleeve 201 is fixedly installed on the outer arc surface of the arc plate 6. A limit frame 204 is fixedly installed on the inner ring wall of the sleeve 201 at the opening. A second spring 202 is provided inside the sleeve 201. One end of the second spring 202 is fixedly connected to the inner wall of one side of the sleeve 201, and the other end of the second spring 202 is fixedly connected to a limit plate 203. A support rod 205 is fixedly installed on the side of the limit plate 203 away from the second spring 202. The end of the support rod 205 away from the limit plate 203 is fixedly installed on the inner arc surface of the arc-shaped anti-collision plate 4.

[0042] As can be seen from the above, by setting spring 202, when the ship hull collides with the anti-collision roller 303, the impact force is transmitted to the support rod 205 through the arc-shaped anti-collision plate 4. The support rod 205 pushes the limiting plate 203 to move axially along the sleeve 201. The movement of the limiting plate 203 compresses spring 202. The impact energy is absorbed by the elastic deformation of the spring, and the instantaneous impact force is converted into a gradual buffer force, reducing the direct impact on the bridge pier column 5. The limiting frame 204 at the opening of the sleeve 201 constrains the movement direction of the support rod 205, preventing spring 202 from shifting or twisting when compressed, ensuring that the buffering process is stable and controllable. Through the synergistic effect with the anti-collision mechanism 3, the collision friction is reduced by the rolling of the anti-collision roller 303, and the remaining impact force is further reduced by the compression of spring 202, forming a dual protection of "rolling buffer + elastic shock absorption", which significantly improves the impact resistance of the bridge pier.

[0043] refer to Figure 2 As shown, two fixed plates 10 are fixedly installed on both sides of the two floating plates 7, and threaded holes are opened on one side of multiple fixed plates 10. The two adjacent fixed plates 10 are connected by bolt threads on one side.

[0044] As can be seen from the above, by setting the threaded holes and fixing plates 10, personnel can adapt the two floating plates 7 to the outside of the pier column 5, and then firmly connect the two adjacent fixing plates 10 with bolts, so that the two floating plates 7 can stably surround the outside of the pier column 5.

[0045] 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.
