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,...

Problems solved by technology

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 work is affected. At the same time , prone to accidental misses resulting in falling objects, posing a threat to personal and equipment safety

Although the lifting block is labor-saving, its weight is several times that of the equal-height rope, which increases unnecessary manpower transportation. At the same time, due to the long lifting point of the block block, the object cannot be hoisted to a higher place. installation location

However, the small DC electric winch is restricted by the battery capacity, unstable performance and different weight factors of the objects, which affects the reliability of the work, and the battery needs professional maintenance, and the weight of the battery will cause unnecessary human transportation.
