Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As can be seen from fig. 1 and 2, the connection device for preventing torsion of a tower crane wire rope in this embodiment includes a pull ring 1, a torsion preventing rotator 2, a yoke plate 3, a wire clamp 4, a wedge 5 and a wire rope 6.
The pull ring 1 is a circular ring with an ear seat.
The anti-torsion rotator 2 can be divided into an upper end and a lower end, and the upper end and the lower end are respectively connected and fixed with an inner ring and an outer ring of the rotating bearing, so that the upper end and the lower end of the anti-torsion rotator can stably rotate while stretching.
