AI Technical Summary

Technical Problem

In the prior art, the windproof mechanism designed on the outside of the column of a ship crane is prone to resonance in a gust-strong environment, resulting in unstable shaking of the column structure.

Method used

An integrated column structure is designed and equipped with a locking structure to lock the column structure in a strong gust and wind environment to avoid resonance shaking. The specific implementation includes setting up a movable locking block and a gyro stabilization structure in the column seat structure, and driving the movable locking block to move inward through a telescopic rod, and inserting the external locking block into the locking slot to lock the gyro stabilization structure.

Benefits of technology

Through the design of the locking structure, the column structure can be fixed in a gust and strong wind environment, avoiding the occurrence of resonance phenomena, and improving the stability and safety of the crane.

Abstract

The invention relates to the technical field of crane stand column structures, in particular to a high-strength and high-stability ship crane stand column frame structure which comprises a ship crane cross beam, a telescopic beam is movably installed at the front end of the ship crane cross beam, and a rotating stand column frame structure is arranged below the ship crane cross beam. The device has the beneficial effects that the structure of the crane stand column base is designed to be matched with the structure of the rotating stand column frame, and during normal work, the stand column supporting disc and the movable locking block are kept consistent and surround the outer side of the gyro-imitating stable structure, so that the limiting effect is achieved, and the whole device can resist external force possibly causing overturning; the telescopic rod works to drive the movable locking block to synchronously move inwards, at the moment, the movable locking block, the built-in locking block and the movable extrusion tongue synchronously move, the external locking block is inserted into the locking groove, the gyro-like stable structure is locked, the overall stability is improved, and the possibility of overturning caused by strong wind is avoided.
