A small torque retractable rope reel

Abstract

The invention discloses a low-torque retracting rope winding drum. The low-torque retracting rope winding drum comprises a winding drum body fixed onto a rotating shaft, wherein the winding drum body comprises a winding drum shaft arranged on the rotating shaft in a sleeving mode; two side discs are arranged on the two sides of the winding drum shaft; a plurality of wire winding rods are arranged outside the winding drum shaft between the two side discs; a fixed support is fixed on the winding drum shaft; a hanging rope wheel is assembled on the fixed support at the position corresponding to the center of the winding drum shaft; one end of a steel wire rope is fixed onto the hanging rope wheel, and the other end of the steel wire rope is wound on one rope winding rod. The hanging rope wheel is additionally arranged on the low-torque retracting rope winding drum, and is arranged at the position corresponding to the center of the winding drum shaft; the steel wire rope is fixed onto the hanging rope wheel, so that when the steel wire rope is retracted by the winding drum, the torque of the winding drum is reduced by the stress at the center of the rotating shaft, and then a rotating assembly is protected, so that the stability and reliability of the equipment are improved, and the maintenance cost of the equipment is reduced.

Description

technical field [0001] The invention relates to a reel, in particular to a small-torque retractable rope reel for a hanging basket. Background technique [0002] The hanging basket is a construction machine used for high-altitude operations in construction projects. It is used for curtain wall installation and exterior wall cleaning. The hanging basket is a new type of high-altitude operation equipment that can replace traditional scaffolding, reduce labor intensity, improve work efficiency, and can be reused. The use of building hanging baskets has gradually become a trend, and it has been widely recognized in high-rise operations such as exterior wall construction, curtain wall installation, thermal insulation construction, maintenance and cleaning of exterior walls of high-rise multi-storey buildings, and can be used for large tanks, bridges, etc. and dams and other projects. Use the hanging basket to avoid scaffolding. The construction cost is reduced, the constructio...

AI Technical Summary

Problems solved by technology

[0003] At present, the retractable rope mechanism of the hanging basket is equipped with a retractable rope reel through the rotating shaft, and one end of the steel wire rope is fixed on the retractable rope reel, so that when the steel wire rope is retracted and released, a large torque will be generated on the rotating shaft. As a result, the shaft assembly is prone to failure, the stability and reliability of the equipment are poor, and there are certain safety hazards
