Description

Guy system with good stability
Technical Field
The invention relates to the technical field of cranes, in particular to a guy system with good stability.
Background
A crane refers to a multi-action lifting machine that vertically lifts and horizontally conveys weights within a certain range. For part of heavy cranes, if the tonnage of the lifted weight is too large, the weight shakes greatly in the lifting process, and the condition that the weight hits the crane arm frame possibly occurs, so that safety accidents are caused.
Therefore, in order to improve the safety of the crane when lifting a heavy object, a guy winch is usually arranged on the crane when lifting the heavy object with excessive tonnage, and a steel wire rope of the guy winch is connected with the heavy object. In the existing guy mechanism, a fixed pulley is mostly arranged on a suspension arm of a crane as a fulcrum, so that the steel wire rope of a guy winch keeps constant tension, the stability is improved, and when the crane lifts a heavy object, the steel wire rope of the guy winch is driven by the heavy object to become loose, the steel wire rope of the guy winch is controlled to maintain constant tension by winding and unwinding the steel wire rope through the guy winch, and the steel wire rope of the guy winch exerts a certain balance force on the heavy object to reduce the shaking of the heavy object. However, in this adjustment mode, the amplitude of adjustment that can shake the heavy object is less for each time the guy winch carries out the action of receiving and releasing wire rope, leads to guy winch whole to shake the adjustment time for the heavy object longer, influences the lifting efficiency of heavy object.
For example, patent document No. 2022111839363 and publication No. 2023.01.13 disclose a crane sliding guy device, in which a pulley is provided, and the pulley is driven by a cable to move so as to apply a balancing force to a counterweight, thereby realizing stability of the counterweight. However, this structure uses only one cable to drive the trolley, so that only one side of the trolley is pulled by the cable, and when the boom swings up and down, the trolley is easily caused to slide at the lower end of the guide rail due to gravity, and only one cable is used, so that the trolley is easily deviated to one side when guy cables are added.
