Crane telescopic arm positioning and fixing equipment for water conservancy ship

Abstract

The invention relates to crane telescopic arm positioning and fixing equipment for a water conservancy ship. The crane telescopic arm positioning and fixing equipment comprises a base mechanism and amain stretching mechanism, the lower end of the base mechanism is installed on the existing working ground, and the main stretching mechanism is arranged at the right end of the base mechanism. A telescopic arm of a crane for the water conservancy ship is positioned and fixed by adopting the design concept of multiple rotatable structures. The base mechanism and the main stretching mechanism are matched to achieve multi-angle and multi-height and length size change of the whole crane telescopic arm positioning and fixing equipment, and then the adaptability of the whole crane telescopic arm positioning and fixing equipment to cargo hoisting at different positions is improved.

Description

technical field [0001] The invention relates to the field of water conservancy ship machinery, in particular to positioning and fixing equipment for the telescopic arm of a crane used in water conservancy ships. Background technique [0002] The definition of water conservancy ship usually refers to a "ship" specialized in some kind of water or underwater engineering, on which a complete set of working machinery is installed to complete specific work tasks, such as channel guarantee, port operation, water conservancy construction, offshore construction, salvage, salvage, Cargo supply and transportation, etc., including dredgers, crane ships, piling ships, cable laying ships, salvage and salvage ships at sea, floating docks, diving work ships, etc. Ships such as transport ships and other types of ships use marine cranes. Marine cranes are used for loading and unloading machinery on ships. They are mainly composed of telescopic booms, lifting columns, rigging and winches. The ...

AI Technical Summary

Problems solved by technology

[0003] 1. The telescopic arm of a common crane can only be rotated up and down in a small range to achieve a small change in the overall height, and a small change is likely to cause collision or movement limitation between the hoisted goods and the telescopic arm. At the same time, when faced with the situation that the distance from the hull is far away or the overall volume of the cargo is large, the distance between the telescopic arm of the crane and the cargo in the height direction and the horizontal direction cannot be effectively controlled and adaptively changed;

[0004] 2. The crane does not have the function of horizontal multi-angle rotation or can only perform a small range of horizontal rotation, and the overall equipment has a low applicability to lifting goods in different situations, and at the same time, the angle accuracy of the small range rotation of the crane is low , and the overall fixation degree after the crane rotates is low
