Description

Technical Field

[0001] The utility model relates to the technical field of bridge protection, in particular to a bridge pier anti-collision mechanism. Background Art

[0002] Bridge construction is one of the most important infrastructure projects currently. Bridges are mainly composed of piers and bridge decks. The piers of water-spanning bridges are located in the water body, and passing ships pass between the two piers. However, there are too many uncontrollable factors during the navigation of ships, such as wind and water flow. Therefore, the heading of ships is different from that of vehicles, and it is more difficult to accurately control the heading of ships. When the wind is strong and the water flow is fast, ships are prone to lose accurate directional control and collide with the piers, causing damage to the bridge and the ship.

[0003] Patent No. CN214883441U in the prior art discloses an anti-collision device for protecting bridge piers, including a bridge pier and an anti-collision mechanism arranged outside the bridge pier, the anti-collision mechanism including a protective plate, an anti-collision plate and a buffer plate, and the anti-collision plate is located between the protective plate and the buffer plate, a spring and a moving rod are arranged between the anti-collision plate and the buffer plate, and the moving rod is distributed on one side of the spring, a first bead groove and a second bead groove are opened on the outer circumference of the protective plate, and the inside of the first bead groove and the second bead groove are embedded with balls, and a third bead groove is arranged on the outer circumference of the buffer plate; the anti-collision plate is composed of four arc-shaped plates connected end to end, and the coordinated work of the spring and the moving rod is realized to drive a single arc-shaped anti-collision plate to move along the extension and contraction direction of the spring when it is hit, thereby reducing the probability of deformation of the anti-collision plate while protecting the bridge pier, which is conducive to the reuse of the anti-collision device.

[0004] The above-mentioned anti-collision device for protecting bridge piers still has certain defects during use. Since the position of the anti-collision mechanism is fixed, it can only protect the fixed position of the bridge pier. With the influence of environmental climate, the water level of the river channel often changes, resulting in the inability to effectively protect the bridge piers at different water levels, and the protection effect is poor. Therefore, a bridge pier anti-collision mechanism is proposed to solve the above-mentioned problems. Utility Model Content

However, with the influence of environmental climate, the water level of the river channel often changes, resulting in the inability to effectively protect the bridge pier at different water levels and poor protection effect.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a bridge pier anti-collision mechanism, comprising a pier body, a mounting seat provided on the outer wall of the pier body, a protective assembly provided on the outer side of the mounting seat, and a lifting mechanism provided on the upper side of the mounting seat;

[0007] The protection assembly includes a first arc-shaped sleeve, the outer side of the first arc-shaped sleeve is fixedly connected to a cushioning airbag, and the outer side of the cushioning airbag is fixedly connected to a second arc-shaped sleeve;

[0009] Furthermore, the first arc-shaped sleeve is fixedly mounted to the outside of the mounting seat, and the drive motor is fixedly mounted to the inside of the pier body.

[0010] Furthermore, the number of the mounting seat, the first arc-shaped sleeve and the second arc-shaped sleeve are both two, and they are respectively located on the left and right sides of the pier body, and a plurality of buffer airbags are provided between the first arc-shaped sleeve and the second arc-shaped sleeve.

[0011] Furthermore, both ends of the rotating rod respectively penetrate the left and right sides of the pier body, and the number of the traction wheels and the number of the steel cables are both two.

[0012] Furthermore, a lifting ring is fixedly connected to the upper side of the mounting seat, and the lower end of the steel cable is fixedly connected to the lifting ring.

[0016] Compared with the prior art, the present invention provides a bridge pier anti-collision mechanism with the following beneficial effects:

[0017] The pier anti-collision mechanism utilizes a first arc-shaped sleeve, a buffer airbag, and a second arc-shaped sleeve to provide anti-collision protection for the outer wall of the pier body, thereby reducing damage to the pier body caused by collisions with other objects on the water surface. By starting a drive motor, the traction wheel can be driven to rotate, and the traction wheel is utilized to retract and release the steel cable to adjust the height of the mounting seat and the height of the protective component. When the water level changes, the protective component can be adjusted to the current water level, thereby preventing the protective component from losing its function when the water level rises or falls, ensuring the protective function of the protective component, and improving the applicability of the device, with good protective performance and high practicality.
