A kind of marine compact deck folding crane

Abstract

The present invention provides a marine compact deck folding crane, which includes a deck pod, an installation base, a pin hole, a plunger of a rotary cylinder, a limit hinge mechanism, a pin, a first boom, a telescopic cylinder, Auxiliary boom 1, auxiliary boom 2, hinge, pod cover, screw group, fixed base, rotary cylinder 2, lifting tripod, movable hinge, cylinder body of retractable cylinder 2, piston rod of telescopic cylinder 2, rotating beam Shaft, pulley, second boom, auxiliary pod cover; when in use, the folding crane is unfolded step by step through the hydraulic cylinder control system, and the rotary cylinder one drives two groups of first booms, two groups of lifting tripods and two groups of second cranes. The arm rotates 90 degrees, and then the extension of the telescopic cylinder pushes the lifting tripod and the second boom to make the first boom fit the deck; the second rotary cylinder drives the lifting tripod and the second boom to rotate, so that the lifting tripod and the deck Fitting; finally telescopic cylinder two promotes the rotation of the second boom, and lowers the suspension rope through the pulley. The invention is suitable for recycling machines and transport machines.

Description

technical field [0001] The invention relates to a marine compact deck folding crane, which belongs to the technical field of marine launching recovery. Background technique [0002] In recent years, with the rapid development of technology and cross-border integration, the exploration and development capabilities of marine resources have also achieved great progress. The 2019 China Ocean Economy Expo showcased new technologies and achievements in the field of marine engineering equipment, and the launching and recycling of these unmanned ships, marine robots and marine detectors are inseparable from marine cranes. At present, most domestic gantry cranes, tower cranes and single-arm folding cranes are used to realize launching and recovery equipment. Although these marine cranes have many advantages, they also have some disadvantages, that is, the cranes are self-heavy, high center of gravity, and large in size. Most of these cranes are installed on the deck, which has a cer...
