Anti-twist device for tail rope of hoist

Abstract

The utility model relates to the field of hoist accessory, concretely relates to a hoist tail rope anti -twisting device, including fixed frame and two groups of constraint frame, two groups of constraint frame are respectively rotationally arranged in fixed frame both sides, the opposite side middle part of two groups of constraint frame all are fixed with limit stop, two limit stops opposite sides can mutually adhere, two groups of constraint frame opposite sides both sides all are provided with inner branch and outer branch, and the inner branch and the outer branch of adjacent position are located constraint frame same side, and the inner branch is located in the inner side of outer branch and can mutually abut tightly, and adjacent inner branch and outer branch constitute the blocking structure, the utility model discloses when one side tail rope occurs torsion and extrudes this side inner branch, not only does this inner branch limit the constraint of tail rope, still through the abutment cooperation with the outer branch of same side, the tail rope pressure of self -sustaining is conducted to the constraint frame of another side, thereby when tail rope deflection is by both sides constraint frame synchronous provides the constraint force of constraint, and the tail rope pressure is borne in common, effectively suppresses the deflection of tail rope.
