Description

Hoisting hook mechanism of straight arm type overhead working truck Technical Field The invention relates to the technical field of hoisting hooks, in particular to a hoisting hook mechanism of a straight arm type overhead working truck. Background The hoisting hook is the most common lifting appliance in hoisting machinery, the lifting hook is often hung on a steel wire rope of a hoisting mechanism by means of a pulley block and other parts, and in general high-altitude operation, the hoisting hook is mostly needed. In the prior art, the traditional hoist lifting hook has larger defects, such as the traditional hoist lifting hook is mostly pulled by a steel wire rope, when some weights are lifted to move, the lifting hook can shake due to inertia, so that lifted materials swing, and dangerous situations such as material falling and the like are easily caused, and therefore, the invention provides the hoist lifting hook mechanism of the straight arm type overhead working truck, and the problems are solved. Disclosure of Invention The invention aims to solve the defects in the prior art, and provides a hoisting lifting hook mechanism of a straight arm type overhead working truck, which is provided with an anti-swing mechanism, so that a guide rod can reduce swing amplitude under the action of a magnetic field according to an electromagnetic damping principle until the swing amplitude is gradually stable.
