Description

Rotary rope guider of travelling crane lifting hook Technical Field The utility model relates to the field of crane lifting hook rotary rope guide. Background In modern industrial hoisting operations, the rope guides of the travelling crane hooks are critical to ensure an orderly arrangement of the steel wire ropes and to reduce wear. The traditional rope guider usually adopts a structure of a single metal plate with a guide groove, and the design can initially guide the trend of the steel wire rope, but has a plurality of limitations in practical application. The direct contact between the guide groove and the steel wire rope causes larger sliding friction force, so that the steel wire rope can be accelerated to wear after long-term operation, the service life of the steel wire rope is reduced, and the replacement frequency and the replacement cost are increased. The angle of the guide groove is not adjustable once being determined, and is difficult to flexibly adapt to the change of steel wire ropes with different diameters or operation scenes, so that the guide effect is poor. In addition, the whole structure of the guide groove is huge, the space is occupied, interference with peripheral equipment is easy to occur in a narrow working environment, and the application range of the guide groove is limited. The root of these drawbacks lies in the static contact manner of the traditional rope guides and their rigid and non-adjustable structure, which makes it difficult to meet the high demands of modern hoisting operations on efficiency, durability and flexibility. Disclosure of utility model Therefore, it is necessary to provide a rotary rope guide of a crane hook, which solves the problems that the static contact mode of the traditional rope guide and the rigid and non-adjustable structure thereof are difficult to meet the high requirements of modern hoisting operation on efficiency, durability and flexibility. The utility model provides a rotary rope guider of a traveling crane lifting hook, which comprises a first bracket, a U-shaped plate and a rotary device, wherein the upper end of the first bracket is fixedly connected with the closed side of the U-shaped plate, the lower end of the first bracket is fixedly connected with a shell of the traveling crane lifting hook, the rotary device comprises a base, a rotary shaft and a roller, the base is fixedly connected with the U-shaped plate, two ends of the rotary shaft are respectively and rotatably connected into a pair of bases, the roller is sleeved outside the rotary shaft, and a plurality of rotary devices are arranged in parallel at least two openings of the U-shaped plate at intervals, and the intervals are not smaller than the diameters of steel ropes of the traveling crane lifting hook. Further, the number of the rotating devices is four, and the four rotating devices are symmetrically distributed at the opening of the U-shaped plate in an upper-lower double-layer mode. Further, the crane lifting hook also comprises a second bracket, wherein the upper end of the second bracket is fixedly connected with one end of the U-shaped plate, and the lower end of the second bracket is fixedly connected with the shell of the crane lifting hook. Further, the crane lifting hook further comprises a supporting plate, wherein the supporting plate is arranged between the first bracket and the shell of the crane lifting hook or between the second bracket and the shell of the crane lifting hook. Further, the first support and the second support are fixedly connected with the shell of the crane hook through fasteners. Further, at least two through holes are formed in the base, screw holes matched with the through holes are formed in corresponding mounting positions of the U-shaped plates, and the base is fixedly connected with the U-shaped plates through the cooperation of the double-end studs and the nuts. Further, screw holes for realizing fixed connection with the base on the U-shaped plate are arranged in an array in the direction perpendicular to the rotating shaft.
