Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge protection technology, and in particular to a bridge pier anti-collision buffer protection device. Background Technology
[0002] As the core load-bearing component of a bridge structure, the safety of bridge piers is directly related to the overall stability of the bridge and the safety of traffic. In recent years, with the increase in the density of waterway transportation and the rise in the number of overpasses, accidents involving ships and vehicles colliding with bridge piers have occurred frequently, resulting in damage to the bridge structure (such as concrete cracking and exposed steel bars), secondary disasters such as traffic interruption (such as ship leakage pollution and vehicle fires), etc.
[0003] Existing bridge protection structures lack elastic buffer devices. When a car collides with a bridge railing, it causes severe damage to the protective structure, with the bridge pillars being the most critical component. Cracks in these pillars pose significant safety hazards, are difficult to repair, and result in high economic costs. Furthermore, if the impact force is too great, the existing bridge pillar structure is unstable and may break, causing the car to fall off the bridge, resulting in secondary injuries and even more serious casualties.
[0004] An existing patent (publication number: CN216999293U) discloses a buffer-type bridge anti-collision protection device, including a column and a base plate. The base plate has mounting holes. Symmetrically distributed sliding grooves are provided on both ends of the base plate, and sliding rods are matched and installed in the sliding grooves. A protective structure is also provided between the two sliding rods. This device ultimately forms a triple protection effect for the bridge column, avoiding the problems of bridge columns being easily damaged by impacts, difficult maintenance, and high maintenance costs. It further improves the anti-collision and buffering force dissipation effect.
[0005] Existing patents offer solutions to the above problems, but they cannot effectively unload or transfer the impact force when a bridge is hit, resulting in an inability to provide effective impact buffer protection for the bridge.
[0006] Therefore, a bridge pier anti-collision buffer protection device is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide a bridge pier anti-collision buffer protection device, which can solve the problem that existing bridge anti-collision protection devices cannot effectively unload and transfer the impact force when the bridge is hit, thus failing to provide effective impact buffer protection for the bridge.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a bridge pier anti-collision buffer protection device, comprising a column, two semi-circular plates bolted to the side wall of the column, a connecting seat provided on the side wall of the semi-circular plates, an mounting seat provided on one side of the connecting seat, an anti-collision barrel provided in the middle of the mounting seat, a buffer mechanism provided between the connecting seat and the mounting seat, and a connecting mechanism provided between the connecting seat and the semi-circular plates;
[0009] The buffer mechanism includes a buffer cylinder disposed on the side wall of the connecting seat, a T-shaped rod disposed on the side wall of the mounting seat, the T-shaped rod being movably disposed inside the buffer cylinder, a mounting cover disposed at one end of the buffer cylinder, a buffer spring disposed between the buffer cylinder and the T-shaped rod, a telescopic bottle disposed at the top of the buffer cylinder, hydraulic oil disposed between the buffer cylinder and the T-shaped rod, and an alarm component disposed at the top of the buffer cylinder.
[0010] Preferably, the alarm assembly includes a limiting cylinder disposed on the top of the buffer cylinder, the telescopic bottle is located inside the limiting cylinder, the top of the limiting cylinder is provided with a top cover, the middle of the top cover is provided with an abutment switch, the top of the top cover is provided with an audible and visual alarm, the abutment switch is electrically connected to the audible and visual alarm, and the top of the telescopic bottle is adapted to the abutment switch.
[0011] Preferably, the connecting mechanism includes a T-slot on the side wall of the semicircular plate, a T-strip adapted to the T-slot is provided on the side wall of the mounting seat, and the connecting seat is bolted to the semicircular plate.
[0012] Preferably, the side wall of the connecting seat is provided with two guide bars, and the side wall of the mounting seat is provided with two slide bars, the slide bars being movably connected to the guide bars.
[0013] Preferably, the anti-collision barrel is hollow, and two plugs are provided on the side wall of the anti-collision barrel.
[0014] Preferably, the connecting seat has two guide cylinders at both ends, and the mounting seat has two guide rods on its side wall. The guide rods are movably connected to the guide cylinders, and a support spring is provided between the guide rods and the guide cylinders.
[0015] Preferably, a connecting groove is provided on the side wall of the semicircular plate, and a connecting strip is provided on the side wall of the other semicircular plate, the connecting strip being adapted to the connecting groove.
[0016] Preferably, a sealing ring is provided at one end of the T-shaped rod, and the sealing ring is in contact with the buffer cylinder.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application incorporates a buffer mechanism. When a ship or vehicle collides with the crash barrier, the rotation of the crash barrier transfers the impact force, preventing the impact force from acting directly on the column. The T-shaped rod compresses the buffer spring, which deforms and absorbs part of the impact energy, reducing the initial impact peak. The T-shaped rod continues to compress the hydraulic oil, which flows through the telescopic bottle on the side wall of the buffer cylinder, generating damping force to further absorb the remaining energy. This achieves double buffer protection for the crash barrier when it is impacted, effectively dissipating the impact force on the crash barrier and improving the protection effect on the column.
[0019] 2. This application incorporates a connecting mechanism. In this process, the two semicircular plates are connected through connecting grooves and connecting strips, allowing the two semicircular plates to adhere to the column. The semicircular plates are bolted to the column, thus achieving the installation and fixation of the semicircular plates. Through the cooperation of T-slots and T-strips, and simultaneously through the bolted cooperation between the connecting seat and the semicircular plate, the connecting seat can be quickly disassembled and replaced. This achieves a modular design for the anti-collision buffer protection device, facilitating the disassembly and replacement of the protection device. Attached Figure Description

Detailed Implementation
[0029] 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.
[0030] Please see Figures 1 to 6 This utility model provides a technical solution:
[0031] A bridge pier anti-collision buffer protection device includes a column 1, two semi-circular plates 2 are bolted to the side wall of the column 1, a connecting seat 3 is provided on the side wall of the semi-circular plate 2, an mounting seat 4 is provided on one side of the connecting seat 3, an anti-collision barrel 5 is provided in the middle of the mounting seat 4, a buffer mechanism 6 is provided between the connecting seat 3 and the mounting seat 4, and a connecting mechanism 7 is provided between the connecting seat 3 and the semi-circular plate 2.
[0032] The buffer mechanism 6 includes a buffer cylinder 61 disposed on the side wall of the connecting seat 3, a T-shaped rod 62 disposed on the side wall of the mounting seat 4, the T-shaped rod 62 being movably disposed inside the buffer cylinder 61, a mounting cover 63 disposed at one end of the buffer cylinder 61, a buffer spring 64 disposed between the buffer cylinder 61 and the T-shaped rod 62, a telescopic bottle 65 disposed at the top of the buffer cylinder 61, hydraulic oil disposed between the buffer cylinder 61 and the T-shaped rod 62, and an alarm component 67 disposed at the top of the buffer cylinder 61.
[0033] Specifically, such as Figure 4 As shown, the alarm assembly 67 includes a limiting cylinder 671 disposed on the top of the buffer cylinder 61, a telescopic bottle 65 located inside the limiting cylinder 671, a top cover 672 disposed on the top of the limiting cylinder 671, an abutment switch 673 disposed in the middle of the top cover 672, an audible and visual alarm 674 disposed on the top of the top cover 672, the abutment switch 673 is electrically connected to the audible and visual alarm 674, and the top of the telescopic bottle 65 is adapted to the abutment switch 673.
[0034] Specifically, such as Figure 5As shown, two guide bars 8 are provided on the side wall of the connecting seat 3, and two slide bars 9 are provided on the side wall of the mounting seat 4. The slide bars 9 are movably connected to the guide bars 8.
[0035] Specifically, such as Figure 3 As shown, the crash barrier 5 is hollow, and two plugs 10 are provided on the side wall of the crash barrier 5.
[0036] Specifically, such as Figure 6 As shown, two guide cylinders 11 are provided at both ends of the connecting seat 3, and two guide rods 12 are provided on the side wall of the mounting seat 4. The guide rods 12 are movably connected to the guide cylinders 11, and a support spring 13 is provided between the guide rods 12 and the guide cylinders 11.
[0037] Specifically, such as Figure 4 As shown, a sealing ring 16 is provided at one end of the T-shaped rod 62, and the sealing ring 16 is in contact with the buffer cylinder 61.
[0038] In use, when a ship or vehicle collides with the crash barrier 5, the rotation of the crash barrier 5 transfers the impact force, preventing the impact force from acting directly on the column 1. The crash barrier 5 is hollow, allowing fine sand to be injected inside. The sand can be easily replaced through the plug 10. The impact force is transmitted to the T-shaped rod 62 through the mounting base 4. The T-shaped rod 62 slides inward along the inner wall of the buffer cylinder 61, triggering the following buffering processes in sequence: First-stage buffering: the T-shaped rod 62 compresses the buffer spring 64 to absorb part of the impact energy, reducing the initial impact peak; Second-stage buffering: the T-shaped rod 62 continues to compress the hydraulic oil, which flows through the telescopic bottle 65 on the side wall of the buffer cylinder 61, generating damping force to further absorb the impact. The remaining energy is used to form a dynamic seal between the sealing ring 16 at the end of the T-shaped rod 62 and the inner wall of the buffer cylinder 61 to prevent hydraulic oil leakage. When the impact force exceeds the preset threshold, the sliding distance of the T-shaped rod 62 increases, pushing the telescopic bottle 65 to move upward along the limiting cylinder 671. The top of the telescopic bottle 65 contacts the contact switch 673 in the middle of the top cover 672, triggering the audible and visual alarm 674 to sound an alarm. After the impact ends, the buffer spring 64 pushes the T-shaped rod 62 to reset, and the telescopic bottle 65 retracts under the elastic action. The contact switch 673 is disconnected and the alarm stops. In this way, double buffer protection is achieved when the anti-collision barrel 5 is impacted, effectively dissipating the impact force on the anti-collision barrel 5 and improving the protection effect on the column 1.
[0039] Specifically, such as Figure 5 As shown, the connecting mechanism 7 includes a T-slot 71 provided on the side wall of the semicircular plate 2, and a T-slot 72 adapted to the T-slot 71 is provided on the side wall of the mounting base 4. The connecting base 3 is bolted to the semicircular plate 2.
[0040] Specifically, such as Figure 5As shown, a connecting groove 14 is provided on the side wall of the semicircular plate 2, and a connecting strip 15 is provided on the side wall of the other semicircular plate 2. The connecting strip 15 is adapted to the connecting groove 14.
[0041] In use, the two semicircular plates 2 are connected by the connecting groove 14 and the connecting strip 15, so that the two semicircular plates 2 are attached to the column 1. The semicircular plates 2 are bolted to the column 1 and fixed to the column 1, thus realizing the installation and fixation of the semicircular plates 2. Through the cooperation of the T-slot 71 and the T-strip 72, and through the bolted cooperation of the connecting seat 3 with the semicircular plates 2, the connecting seat 3 can be quickly disassembled and replaced. In this way, the modular setting of the anti-collision buffer protection device is realized, which facilitates the disassembly and replacement of the protection device.
[0042] By adopting the above technical solution, the problem that existing bridge collision protection devices cannot effectively unload and transfer the impact force when the bridge is hit is solved, resulting in the inability to provide effective impact buffer protection for the bridge.
[0043] Working principle: In use, the two semicircular plates 2 are first connected by the connecting groove 14 and the connecting strip 15, so that the two semicircular plates 2 are attached to the column 1. The semicircular plates 2 are bolted to the column 1 and fixed thereon. Through the cooperation of the T-slot 71 and the T-strip 72, and the bolted cooperation of the connecting seat 3 with the semicircular plates 2, the connecting seat 3 can be quickly disassembled and replaced. When ships, vehicles, etc. collide with the anti-collision barrel 5, the rotation of the anti-collision barrel 5 transfers the impact force, preventing the impact force from acting directly on the column 1. The anti-collision barrel 5 is hollow and can be filled with fine sand. The impact force is transmitted to the T-bar 62 through the mounting seat 4. The T-bar 62 slides inward along the inner wall of the buffer cylinder 61, triggering the following buffering process in sequence: First-stage buffering, T-bar 62 compression buffering. Spring 64 deforms to absorb part of the impact energy, reducing the initial impact peak; in the second stage of buffering, T-shaped rod 62 continues to compress hydraulic oil 66, which flows through telescopic bottle 65 on the side wall of buffer cylinder 61, generating damping force to further absorb the remaining energy. A sealing ring 16 is provided at the end of T-shaped rod 62 to form a dynamic seal with the inner wall of buffer cylinder 61 to prevent hydraulic oil 66 from leaking. When the impact force exceeds the preset threshold, the sliding distance of T-shaped rod 62 increases, pushing telescopic bottle 65 to move upward along guide cylinder 11. The top of telescopic bottle 65 contacts the contact switch 673 in the middle of top cover 672, triggering the audible and visual alarm 674 to sound an alarm. After the impact ends, buffer spring 64 pushes T-shaped rod 62 to reset, telescopic bottle 65 retracts under elastic action, contact switch 673 is disconnected, and the alarm stops.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
