Description

Lifting appliance and lifting equipment for constructional engineering Technical Field The application relates to the field of buildings, in particular to a lifting appliance and lifting equipment for constructional engineering. Background In the field of construction engineering hoisting, a lifting appliance (such as a lifting beam and a rotary lifting hook assembly) is a key device for transferring heavy loads such as prefabricated components, steel structures, reinforcement cages and the like. Although the traditional lifting appliance can realize free rotation of the lifting hook through the bearing structure, continuous shaking often occurs under dynamic working conditions, and construction safety and efficiency are seriously affected. When the crane is in emergency braking in the lifting or translation process, a flexible load (such as a steel reinforcement cage and a net rack) hung below the lifting appliance continuously swings due to inertia, so that the lifting appliance can swing. Or lateral wind force acts on a load with larger slenderness (such as a prefabricated column and a steel truss) during high-altitude operation, so as to induce horizontal sinusoidal oscillation. Or the lifting appliance can shake due to uneven stress of lifting points caused by special-shaped components (such as L-shaped beams and asymmetric equipment). The load in the shaking process is easy to collide with an operation platform, a supporting structure or constructors. The continuous swing (period 5-10 seconds) forces the hoisting to be suspended when the components are butted, and the positioning needs to be adjusted manually and repeatedly.
