Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship cranes, in particular to a ship crane device. Background Art
[0002] Marine cranes are devices and machinery used by ships for loading and unloading cargoes, mainly boom devices, deck cranes and other loading and unloading machinery. However, most marine crane devices do not have good protective performance, which can easily cause damage to objects and hooks due to collisions with the outside world when the hooks are idle.
[0003] A marine crane disclosed in Chinese patent CN205916912U includes a hollow boom, which is cylindrical. The entire boom includes a vertical section and an extension section. A first pulley is provided inside the boom at the connection between the vertical section and the extension section, and a second pulley is provided at the outlet end of the extension section. The steel wire is installed inside the boom through the second pulley and the first pulley from the outside to the inside. The steel wire is wound on a lifting device provided at the bottom of the boom. The steel wire is driven to be wound by the lifting device to control the lifting and lowering of the hook outside the steel wire. Since the steel wire is located inside the boom as a whole, only the very end is exposed, and the other parts are completely inside the boom, rainwater rarely wets the steel wire when it rains, and the lifting device used for winding inside will not be wetted. The steel wire is kept dry to a great extent, thereby improving the service life of the steel wire and reducing the degree of corrosion to the steel wire by rainwater.
