Lifting appliance rotating and horizontally moving mechanism and container crane

Abstract

The invention provides a lifting appliance rotating and horizontally moving mechanism and a container crane and relates to the field of cranes. The lifting appliance rotating and horizontally moving mechanism comprises a trolley, a first pulley assembly, a second pulley assembly, a third pulley assembly, a fourth pulley assembly and a drive component, wherein the first pulley assembly and the second pulley assembly are installed on the trolley in a sliding mode and can slide in the traveling direction of a cart, the third pulley assembly and the fourth pulley assembly are installed on the trolley in a sliding mode and can slide in the traveling direction of the trolley, and the drive component is installed on the trolley and used for driving the pulley assemblies to move. The lifting appliance rotating and horizontally moving mechanism provided by the invention is simple in structure, horizontal movement in the traveling direction of the cart and the traveling direction of the trolley as well as clockwise and anticlockwise rotation movement of a lifting appliance can be achieved through cooperative or differential movement of the pulley assemblies, and the problems that in the prior art, the structure is complex, and horizontal movement of the lifting appliance in the trolley direction cannot be achieved are solved.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a sling rotation and translation mechanism and a container crane. Background technique [0002] During the working process of the container crane, the spreader of the crane needs to be aligned with the position of the container to carry out further lifting, and it is difficult to control the position of the container and the spreader on the same vertical line, so it is necessary to align the spreader The tool can be translated or rotated to adjust the position to align with the container. [0003] Most of the methods used in the prior art to align with the container are to directly use the hydraulic cylinder to push the wire rope to drive the translation or rotation of the spreader. This method makes the overall structure of the mechanism more complicated, and there are certain limitations due to the push , resulting in the existing spreader translation mechanism can only realize the trans...
