Pier anti-collision device implemented through mechanism

Abstract

The invention relates to a pier anti-collision device implemented through a mechanism. The mechanism is a crank, connecting rod and slide tank mechanism and comprises a crank located on the front water area of a pier, a connection rod located on the front water area of the pier, and a long slide tank arranged in a pier bearing table in a sleeved manner or arranged in an anti-collision sleeve box around the anti-collision pier bearing table in a sleeved manner. The crank is connected with a hinge lug of the connection rod. The connection rod is connected with a hinge lug at the end portion of the anti-collision sleeve box. The side face of the head of the anti-collision sleeve box is an inclined face or a streamline hook face. The pier anti-collision device has the beneficial effects that when a ship is off the course and touches the lift hook face of the crank, the crank is made to rotate under the effect of force, the ship moves to the center of a channel under the lifting effect of the lift hook face, the ship advances and touches the head of the anti-collision sleeve box, the ship is pushed to move to the center of the channel under the tangential counterforce effect of the side inclined face or the side streamline hook face of the head of the anti-collision sleeve box, and the course is corrected; and the crank rotates to do work, the anti-collision sleeve box moves to do work, a buffer does work, and the ship consumes energy, reserves most of kinetic energy and sails on the channel.

Description

technical field [0001] The invention relates to the anti-collision protection technology of bridges, which is mainly used for anti-collision devices of bridge piers in sea areas, rivers, etc., to protect the bridge piers in the anti-collision devices to avoid damage due to collision of ships, and can be used for water facilities anti-collision protection. Background technique [0002] With the continuous development of the transportation industry, a large number of cross-sea and cross-river bridges are constantly being built, and the rivers, rivers, lakes, and sea areas where such bridges are located are mostly busy waterways, and the conditions of water flow, waves, and wind waves are complicated. Bridges inevitably bear a certain risk of ship collision. When the pier or bridge body of a bridge is hit by a ship, even if the speed of the ship is very slow, due to the great mass of the ship itself, the momentum of the ship is very large, according to the momentum theorem: mv...

AI Technical Summary

Problems solved by technology

When the flexible anti-collision ring is torn and crushed, the ship will collide with the inner steel ring with the outer steel ring, and there will also be hidden dangers of bridge piers being destroyed, ships breaking, and people dying

[0006] The above-mentioned anti-collision devices are limited to the ship collision protection of 10,000-ton and 20,000-ton ships, and the ship-collision protection of 50,000-ton, 100,000-ton, and hundreds of thousands-ton ships is far from being solved
