A kind of crane telescopic arm positioning and fixing equipment for water conservancy ships

Abstract

The invention relates to a positioning and fixing device for a telescopic arm of a crane for a water conservancy ship, comprising a base mechanism and a main extension mechanism. The lower end of the base mechanism is installed on the existing working ground, and the right end of the base mechanism is provided with a main extension mechanism. The design concept of multiple rotatable structures is used to position and fix the telescopic arm of the crane for water conservancy ships. The cooperation between the base mechanism and the main extension mechanism can realize the change of the overall multi-angle, various height and length dimensions of the equipment, thereby improving the overall response of the equipment to different Applicable rate of cargo hoisting at the location.

Description

technical field [0001] The invention relates to the field of water conservancy ship machinery, in particular to a positioning and fixing device for a telescopic arm of a crane for a water conservancy ship. Background technique [0002] The definition of a water conservancy ship usually refers to a "ship" specializing in some kind of above-water or underwater engineering. It is equipped with a complete set of working machinery to complete specific work tasks, such as waterway assurance, port operations, water conservancy construction, offshore construction, salvage, salvage, Cargo supply and transportation, etc., including dredgers, crane ships, piling ships, cable laying ships, marine rescue and salvage ships, floating docks, diving work ships, etc., including dredgers, crane ships, rescue and salvage ships, and cargo supply Ships such as transport ships and other types of ships use marine cranes. Marine cranes are used to load and unload cargo on ships. They are mainly comp...

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
