Automatic tail rope rolling and releasing manual capstan

Abstract

The invention relates to a manual lifting device, and in particular relates to an automatic tail rope rolling and releasing manual capstan. The automatic tail rope rolling and releasing manual capstan comprises a support, a U-shaped slot grinding core and a grinding core shaft, a left rocker arm and a right rocker arm, wherein the support is provided with a rotatable U-shaped slot tail rope wheel, a driven gear is fixed on one end face of the U-shaped slot tail rope wheel, the driven gear is meshed with an intermediate gear arranged on the support, and the intermediate gear is also meshed with a driving gear fixed on the end face of the U-shaped slot grinding core; and a rear bidirectional pawl is matched with the driven gear fixed on the end face of the U-shaped slot grinding core, and the rear bidirectional pawl is arranged on the support. Only one man is required to operate, the labour force is saved, and a malady that a tail rope of a capstan is required to be pulled by a specific person can be eliminated; and a tail rope automatically advances and retreats along with a hoisting stroke of an article and forward and reverse self-locking shifting forks are adopted, and an accident caused by exhaustion or accidentally drop of operating personnel can be prevented.

Description

technical field [0001] The invention relates to a manual lifting device, in particular to a manual winch with an automatic retractable tail rope. Background technique [0002] At present, the towers in the power generation, power transmission, power transformation, and power distribution equipment are lifted by the small-scale inspection and maintenance of the structure, and the single pulley endless rope or block block is mostly used. One or more people are required to lift objects with a single-block infinite rope. There is no safety device for lifting objects with a single-block infinite rope. The pulling personnel are prone to extreme fatigue and the sustainability of the work is affected. At the same time , It is prone to accidental misses and falling objects from high altitudes, which poses a threat to personal and equipment safety. Although it is labor-saving when the block block is used for lifting, its weight needs to be several times that of the equal-height rope,...
