Double-telescopic self-balancing tower crane for cargo ship

Abstract

The invention provides a double-telescopic self-balancing tower crane for a cargo ship. At ordinary times, a telescopic base assembly and a telescopic self-balancing crane jib assembly in the double-telescopic self-balancing tower crane are contracted, so that the double-telescopic self-balancing tower crane is stopped; during working, the double-telescopic self-balancing tower crane for the cargoship is not limited completely and regionally; and with a telescopic self-balancing crane jib assembly capable of lifting and rotating and a hoisting mechanism inside, cargos can be loaded and unloaded directly at a small or large space between the ship and a wharf, so that the dependency on a wharf crane is eliminated. The double-telescopic self-balancing tower crane for the cargo ship is characterized in that the double-telescopic self-balancing tower crane is hoisted on the cargo ship, and at ordinary times, the telescopic base assembly and the telescopic self-balancing crane jib assemblyin the double-telescopic self-balancing tower crane are contracted, so that the double-telescopic self-balancing tower crane is stopped; and according to the double-telescopic self-balancing tower crane, the telescopic base assembly is arranged on the cargo ship, and a telescopic self-balancing crane jib assembly is placed on a rotating assembly in the telescopic base assembly.

Description

technical field [0001] The invention relates to a ship crane. Background technique [0002] Ship cranes are machinery used by transport ships for lifting, loading and unloading cargo. It is an important part of ships. Due to the limited space on board, various equipment and hull structure layout are very compact, and the stability of ship cranes directly affects the cargo. Carriage safety. For the sake of safety, each ship must add a mandatory automatic limit function when the ship crane is restricted by the installation location and nearby fixed or non-fixed obstacles. The function is divided into two types: full limit and area limit. The complete restriction is the restriction that the crane is not allowed to enter the rotation area under any working conditions; the area restriction is the restriction that the crane can only rotate and enter the area when the elevation angle of the jib frame is higher than a certain angle, and after entering the area , the jib elevation ...

AI Technical Summary

Problems solved by technology

The boom of the folding-arm crane is folded when not in use, and stretched when in use, which has the characteristics of flexibility and convenience, but the load capacity is poor; the boom of the straight-arm crane has always been set vertically, which has overload Ability is strong, but not flexible enough

Both the knuckle-arm crane and the straight-arm crane have relatively single functions, and their applicable operating conditions are limited
