Problems solved by technology

[0003] Due to the influence of water flow, the hydrodynamic characteristics near the bridge pier are complicated. When the ship passes through the bridge and is close to the bridge pier, the ship suction effect often occurs, causing the ship to hit the pier. At the same time, the water flow has a scouring effect on the bridge pier. As time goes by, it is easy to damage the structure of bridge piers and pile foundations, so when the hull hits the pier, it is easy to induce safety hazards

Embodiment 1

[0021] like figure 1 , figure 2 , image 3 A liftable bridge pier anti-collision protection device as shown, it includes a protective fence 1, a plurality of pull ropes 2 are connected to the protective fence 1, and a locking retractor 3 is connected to the pull rope 2. The locking retractor 3 is connected with a weight body 4; the protective fence 1 is a hollow rubber airtight structure, and the cross section of the protective fence 1 is a triangular cone; the side of the protective fence 1 close to the pier A spring 5 is provided, and a convex pull ring 6 is also provided on the protection fence 1 , and the convex pull ring 6 and the protection fence 1 are of an integrated structure.

[0022] This embodiment is placed around the pier, and then the convex pull ring 6 of one protection device is connected with the convex pull ring 6 of the other protection device by rope, so that this embodiment surrounds the pier, and the protection fence of this embodiment 1 is an intern...

Embodiment 2

[0027] This embodiment has been further improved on the basis of embodiment 1, as figure 1 , figure 2 , image 3 As shown in a liftable pier anti-collision protection device, the protective fence 1 is fixedly connected to the pull rope 2, and the locking retractor 3 is fixedly connected to the weight body 4, which strengthens the present embodiment. of firmness.

Embodiment 3

[0029] This embodiment has been further improved on the basis of embodiment 1, as figure 1 , figure 2 , image 3 As shown in a liftable pier anti-collision protection device, the protective railing 1 includes a first guardrail arm 11 and a second guardrail arm 12, and each guardrail includes two first guardrail arms 11 and two second guardrail arms. Two guardrail arms 12, one end of the two first guardrail arms 11 are connected to each other by an arc, and the minimum angle between the two first guardrail arms 11 is 30-60°; each of the first guardrail arms The other end of the arm 11 is connected with a second guardrail arm 12, the first guardrail arm 11 and the second guardrail arm 12 are connected by an arc, and the minimum distance between the first guardrail arm 11 and the second guardrail arm 12 is The included angle is 125-180°, and each second guardrail arm 12 is connected with a convex pull ring 6; the minimum included angle of the two first guardrail arms 12 is 30-...

Abstract

The invention discloses liftable and lowerable bridge pier anti-collision protection devices. The liftable and lowerable bridge pier anti-collision protection devices comprise protection barriers, first protection barrier arms, second protection barrier arms, pulling ropes, lock-up retractors, stopping devices, stopping rings, friction plates, counter-weights, springs, inverted-T-shaped pulling rings and a bridge pier. The protection devices provided by the invention have the beneficial effects that the protection devices are arranged around the bridge pier and the inverted-T-shaped pulling rings of one protection device are connected with the inverted-T-shaped pulling rings of the other protection device by ropes, so that the bridge pier is surrounded with the protection devices; the protection barriers are of a hollow interior and rubber sealed structure to float on the water, so that the protection devices are subjected to certain steadiness action, and the possibility that the protection devices are displaced under the action of water flow or crash of a ship is reduced.

Description

technical field [0001] The invention relates to a bridge pier protection device, in particular to a liftable bridge pier anti-collision protection device. Background technique [0002] With the development of economic construction, there are more and more deep-water bridge projects. As the most important foundation type in bridge engineering, bridge pile foundation is widely used. [0003] Due to the influence of water flow, the hydrodynamic characteristics near the bridge pier are complicated. When the ship passes through the bridge and is close to the bridge pier, the ship suction effect often occurs, causing the ship to hit the pier. At the same time, the water flow has a scouring effect on the bridge pier. As time goes by, it is easy to damage the structure of bridge piers and pile foundations, so when a ship hits a bridge pier, it is easy to induce safety hazards. [0004] Therefore, how to effectively protect the bridge piers and prevent ships from colliding with th...
