Description

Technical Field

[0001] The utility model relates to the technical field of dock anti-collision, in particular to an anti-collision mechanism for a steel trestle at a water transport dock. Background Art

[0002] A trestle-type wharf is an offshore wharf connected to the shore by a trestle. It consists of loading and unloading platforms, mooring piers, and berthing piers. It is suitable for river and sea ports far from the shore in deep water lines and can be used as a professional wharf for loading and unloading materials such as oil, coal, and ore. The steel trestle of the wharf generally needs to be equipped with an anti-collision mechanism to avoid the impact of debris such as tree roots, tree stubs, and drifting ice brought from the upstream by the river.

[0003] The existing device mainly assembles anti-collision components on the outer wall of the pillar of the steel trestle. The existing anti-collision energy absorption device for steel pipe piles of steel trestle, with patent number CN218116569U, includes multiple rows of steel pipe piles arranged along the length direction of the steel trestle; each row has multiple; an anti-collision energy absorption device is arranged on the first steel pipe pile on the water-facing side; the anti-collision energy absorption device has a truss welded on the water-facing side of the steel pipe pile; the length of the truss along the steel pipe pile direction should be greater than the height difference between the 50-year water level and the current water level, that is, the top of the anti-collision energy absorption device is higher than the 50-year water level, and the bottom is lower than the current water level; the truss is welded by multiple angle irons; the outer wall of the truss is welded with steel plates. The utility model effectively ensures the safety of steel pipe piles under the conditions of rapid flow and complex surrounding environment, but the device still has electrical problems that can be optimized.

[0004] The existing device mainly fixes the anti-collision component at the front end of the steel trestle, which makes it difficult for some devices to be raised and lowered according to the water surface height, so that some anti-collision components can face external impact directly. At the same time, some devices mainly use energy-absorbing components to face the impact directly, which makes it difficult for some devices to buffer the force of the anti-collision component, which makes it inconvenient to provide a mobile buffer space for the anti-collision component, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an anti-collision mechanism for the steel trestle of a water transport terminal is proposed. Utility Model Content
