Anti-swing mechanism utilizing non-Newtonian fluid, for crane

Abstract

The invention discloses an anti-swing mechanism utilizing a non-Newtonian fluid, for a crane. The anti-swing mechanism comprises a trolley and a lifting appliance, wherein a hoisting reel is arrangedon the trolley; a plurality of hoisting fixed pulleys are distributed on the lifting appliance; the hoisting reel is connected with the hoisting fixed pulleys through lifting ropes, and drives the lifting appliance to lift; a plurality of support arm fixed pulleys and a plurality of curved-surface reels are further distributed on the trolley; a plurality of non-Newtonian fluid dampers are distributed on the lifting appliance; a plurality of anti-swing ropes are further arranged between the trolley and the lifting appliance; one end of each anti-swing rope is wound on the corresponding curved-surface reel, and the other end of the anti-swing rope is connected with the corresponding non-Newtonian fluid damper on the lifting appliance below via the corresponding support arm fixed pulley; andthe curved-surface reels are connected with the lifting reel. The anti-swing purpose of the lifting appliance of the crane is realized, and the swing of the lifting appliance is greatly reduced, so that the working efficiency of the crane is increased, and the safety performance of the crane is improved.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a crane anti-sway mechanism using non-Newtonian fluid. Background technique [0002] Non-Newtonian fluids refer to fluids that do not satisfy Newton's experimental law of viscosity, that is, fluids that have a non-linear relationship between shear stress and shear strain rate. When the force of the non-Newtonian fluid is small or the impact speed is small, its overall characteristics are similar to that of liquid, but when it is impacted by a sudden change of energy, the non-Newtonian fluid will quickly become a very tough jelly. Its physical performance is that the output damping force increases at low speeds, and the output damping force increases slowly at high speeds. Therefore, non-Newtonian fluid has become a kind of energy-dissipating and shock-absorbing device with excellent performance. At present, non-Newtonian fluids have been widely used as extremely effe...
