Technical Field

[0001] The utility model belongs to the technical field of bridges, and specifically relates to a bridge ship collision prevention device. Background Art

[0002] Bridges are passages for pedestrians and vehicles to cross water, but they are artificial obstacles to ships. A large number of bridges have been built on rivers with busy shipping, and more are planned. However, the increase in navigation density and the increasing size and displacement of ships have led to frequent collisions between ships and bridges.

[0003] For bridges with a large number of ships passing by, anti-collision measures are generally installed to protect the bridges and reduce the impact of accidental collisions with ships.

[0004] Traditional anti-ship collision facilities are composed of anti-collision rubber blocks wrapped and fixed on bridge columns, but the existing structure can only passively withstand collisions, and the anti-collision function depends entirely on the elasticity of the rubber blocks themselves, and the anti-collision function is limited.

[0005] Therefore, it is necessary to seek a multi-faceted composite anti-collision device with strong structural stability and good energy dissipation and anti-collision capabilities, and at the same time have certain preventive functions so that the ship can passively increase the distance from the bridge column.

[0006] For example, the patent document with the authorization announcement number CN209553454U discloses a ship anti-collision facility, which includes a longitudinal track, a welding block, a sliding track groove, a rectangular slider, a connecting rod, a support plate, a floating device and a collision buffer device, wherein the side of the longitudinal track is welded and fixed to the welding block, and the sliding track groove is opened on the front of the longitudinal track. The technical solution disclosed in the patent document also cannot solve the technical problems described above. Utility Model Content

[0009] The anti-collision buffer body is a fan-shaped structure.

[0010] The material of the anti-collision buffer body is rubber.

[0011] A slide rail is arranged on the bridge column, the slide plate is sleeved on the slide rail, a fixing ring is arranged on the bridge column, and a slot for embedding the connecting rod mechanism is arranged on the fixing ring.

[0012] The connecting rod mechanisms are provided in plurality and the number of the connecting rod mechanisms is the same as the number of the anti-collision buffer bodies, each connecting rod mechanism is connected to one anti-collision buffer body, and the number of the slots provided on the fixing ring is the same as the number of the connecting rod mechanisms.

[0013] The link mechanism comprises a first link and a second link, wherein the first link is rotatably connected to the sliding plate and the anti-collision buffer body, and the second link is rotatably connected to the first link and the bridge column.

[0014] The bridge anti-ship collision device of the utility model has a spring that deforms when hit, and the anti-collision buffer body shrinks and gathers to form a ring to wrap the bridge column. At the same time, the connecting rod mechanism moves with the sliding plate to achieve multiple energy dissipation and anti-collision effects, thereby effectively protecting the bridge column and improving the anti-collision capability; when the external force disappears, the device returns to a normal state under the action of gravity.
