The invention discloses a groove-hopping-proof wear-proof rotatable floating holding pole head structure and relates to a rotatable floating holding pole. A current floating holding pole for electric transmission line engineering iron tower assembly is inflexible in rotation, and a hoisting steel wire rope is easy to hop a groove and wear. The groove-hopping-proof wear-proof rotatable floating holding pole head structure comprises a lifting tackle assembly, an outer rope pulling assembly and an inner rope pulling assembly. The lifting tackle assembly comprises two tackle sets in left-right symmetry and main sleeves, the outer rope pulling assembly is rotatably connected to the upper ends of the main sleeves, and the inner rope pulling assembly is rotatably connected to the lower ends of the main sleeves. Tackle side plates for preventing the steel wire rope from slipping laterally are installed on the two sides of each tackle set correspondingly, groove-hopping-proof devices for preventing the steel wire rope from hooping out of tackle grooves are installed on the portions, located on the outer upper portions of the tackle sets, of the tackle side plates, and wear-proof devices are installed on the portions, located on the outer lower portions of the tackle sets, of the tackle side plates. According to the groove-hopping-proof wear-proof rotatable floating holding pole head structure, the groove-hopping phenomenon of the steel wire rope is effectively prevented, friction wear of the steel wire rope and the contact portions is reduced, and using safety of the floating holding pole is improved.
Description
technical field [0001] The invention relates to a rotatable suspension pole, in particular to a rotatable suspension pole head structure which prevents jumping and wear. Background technique [0002] Most of the transmission line engineering towers use suspension poles to hoist the tower materials, and the suspension poles need to be equipped with a pole head for arranging lifting blocks, outer stays, and inner stays. The previous head of the pole has the following problems: the rotation of the head is not flexible; it is easy to cause the safety risk of wire rope damage caused by the lifting wire rope jumping; when the pulley block has a lateral deflection angle, the lifting wire rope is easy to rub against the nearby steel structure And cause wire rope wear. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to improve and improve the existing technical solutions, and to provide a rotatable ...
