Abstract
Provided is a descender. The utility model discloses a cable type descender to solve the problems of the existing cable type (multi-plate type) descenders of being complex in structure controlling and high in processing and manufacturing cost. The descender is provided with a soft controlling rope so that when in hanging, an operating rope is under stress, a tier pole is drawn upwards, friction force of the operating rope is increased, and a human body stops descending. When the soft controlling rope is pulled downwards by hand, the tier pole is released and extended downwards, friction force of the operating rope is decreased, and the human body descends. The descender can not only serve as a suspension tool in constructions such as building out wall cleaning and renovation, but also serve as a suspension tool in building firefighting lifesaving and emergency rescue or aerial lifesaving and operation. In addition, the descender can be used as special equipment for personnel in airborne landing.
Description
Technical field
The utility model relates to a kind of drop device, relate in particular to a kind of with human body self weight be gravity, drop device through hand-guided.
Background technology
In " the single suspender technical specification of security of Cleaning for Outer Wall of Building operation seat board formula ", the kind of drop device comprises now: bar type, winding displacement formula (multi-plate), 8 word ring types and unload button.When adopting 8 word ring type drop devices or unloading the button drop device, operating personnel must up mention free-ended rope when landing; Gravity is very big when rope length is very long, sometimes even the problem of motionless rope occurs putting forward, brings very big trouble for construction and operation.In addition, unload the button drop device, do not advocated use at present owing to there are some safety problems.
Winding displacement formula (multi-plate) drop device is used more extensive, but has many shortcomings such as control structure complicacy, processing and manufacturing cost height.
