Hydraulic foldable arm telescopic crane for ships

Abstract

The invention discloses a hydraulic foldable arm telescopic crane for ships, belonging to the technical field of ship manufacturing. The crane comprises a base, a vertical column and a telescopic suspension arm, wherein the base is welded on a ship deck substrate; the telescopic suspension arm is controlled by a first cylinder; a hoisting winch is mounted at the lower end of the telescopic suspension arm; an inner arm which is folded through a third cylinder is hinged between the top of the vertical column and the telescopic suspension arm; a second cylinder for folding the telescopic suspension arm is arranged below the inner arm and is hinged with two ends of the inner arm, respectively; the bottom end of the vertical column is connected with the base through a slewing bearing; a pump station and a wireless remote receiver are mounted on the vertical column; the first cylinder, the second cylinder and the third cylinder are all communicated with the pump station; the wireless remote receiver is electrically connected with a motor of the pump station through a controller. By adopting the hydraulic foldable arm telescopic crane, the problem that the running speed of a ship body is affected as a crane for the ship can only operate in a single direction and cannot be folded up is solved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a marine hydraulic folding arm telescopic crane. Background technique [0002] A marine crane is a machine used for lifting, loading and unloading cargo of ships transported by sea. A marine crane includes a base welded on the deck base of the ship and a column fixed on the base. The top of the column is hinged with a The telescopic boom controlled by the oil cylinder, the lower end of the telescopic boom is equipped with a hoisting winch, the oil cylinder is connected with the pump station installed on the deck through the pipeline, and the motor of the pump station is electrically connected with the crane controller; this kind of machinery has a 1. Since the base and the column are fixedly connected and the pump station is installed on the deck, the telescopic boom can only be a one-way operation of extending and retracting forward, which is inconvenient to use and affects...
