Description

A sliding and stabilizing device for a crane

technical field

The invention relates to the technical field of cranes, in particular to a sliding and stabilizing cable device for a crane.

Background technique

A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. For some heavy-duty cranes, if the tonnage of the lifted heavy object is too large, and the heavy object shakes greatly during the lifting process, the heavy object may hit the boom of the crane, causing a safety accident.

Therefore, in order to improve the safety of the crane when lifting heavy objects, when lifting heavy objects with an excessive tonnage, a cable-steady winch is usually set on the crane, and the wire rope of the cable-steady winch is connected to the heavy object. Most of the existing cable-stabilizing mechanisms set a fixed pulley on the boom of the crane as a fulcrum, so that the steel wire rope of the cable-stabilizing winch maintains a constant tension and increases stability. When there is an object, the wire rope of the anchor winch will be driven by the heavy object and become loose. The wire rope of the anchor winch is controlled to maintain a constant tension by retracting and releasing the wire rope of the anchor winch, and the steel wire rope of the anchor winch exerts a certain balance force on the heavy object. , to reduce the shaking of heavy objects. However, in this adjustment method, every time the cable-stabilizing winch performs an action of retracting and releasing the steel wire rope, the range of adjustment to the shaking of the heavy object is relatively small, resulting in a longer adjustment time for the entire cable-stabilizing winch to the shaking of the heavy object, which affects the weight of the heavy object. lifting efficiency.
