Steel wire rope hoisting system for crane

Abstract

The invention discloses a steel wire rope hoisting system for a crane. The steel wire rope hoisting system for the crane comprises a trolley frame and a hanger upper frame, wherein the hanger upper frame is positioned at the bottom of the trolley frame; a hoisting drum is fixedly arranged on the trolley frame, a hoisting steel wire rope is wound on the hoisting drum, and the free end of the hoisting steel wire rope penetrates through the trolley frame and is fixedly connected with the hanger upper frame; anti-roll drums are separately arranged at four corners of the upper surface of the trolley frame; and four consolidation points are arranged on the upper surface of the hanger upper frame, and an anti-shake steel wire rope is wound and connected between different anti-roll drums and the consolidation points to realize the anti-roll function of a hanger in the cart direction or the trolley direction. According to the steel wire rope hoisting system for the crane, the anti-roll functionin the cart direction or the trolley direction is realized through the winding connection relation of the anti-shake steel wire rope between the different anti-roll drums and the consolidation points, the anti-roll effect is obvious, and meanwhile, and a trolley running mechanism can run at full speed, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a wire rope hoisting system for a crane. Background technique [0002] Various hoisting systems for cranes are usually composed of wire ropes connected to the upper frame of the spreader, and the upper frame of the spreader and the spreader are then connected to the container. Since the working place of the crane is usually in an open field, the structure of the lifting equipment itself and the environmental factors of the site make the spreader prone to sway and inaccurate positioning of the stack during the lifting and lowering of the cargo. It brings many safety hazards, and inaccurate positioning affects work efficiency, so it is necessary to add anti-sway function and micro-motion function to the lifting system. [0003] At present, the anti-sway function of the hoisting system for cranes is mainly realized by electronic anti-sway. Electronic anti-sway is to detect informati...

AI Technical Summary

Problems solved by technology

However, in the actual operation of electronic anti-rolling, the running speed of the trolley cannot reach the full speed state, and the spreader does not have the function of micro-positioning, which affects the operating efficiency of the whole machine
