Abstract
The invention relates to a descender. The invention provides a bar descender so as to solve the problem that the conventional bar descender is inconvenient to use. The descender is formed by combining a core shaft and an outer sleeve, wherein an outer sleeve rope-sliding port is formed on the outer sleeve; a rope-pressing ring is arranged on the outer sleeve; the rope-pressing ring can slide up and down under the control of hands; when the rope-pressing ring is positioned at the rope-sliding port, the winding rope on the core shaft is extruded, the friction force of the winding rope is increased and a human body stops descending; and when the rope-pressing ring moves upwards and departs from the rope-sliding port, the winding rope is not pressed, the friction force of the winding rope is reduced and the human body descends. The descender can serve as a hanging tool applied to construction, such as cleaning, decorating and the like of building outer walls, can serve as a hanging tool applied to building fire-fighting life saving, rescue or aloft life saving and work, and can also serve as special equipment applied to airborne landing of staff.
Description
Technical field
The present invention relates to a kind of drop device, relate in particular to a kind of drop device take the human body own wt as gravity, by hand-guided.
Background technology
In " the single suspender technical specification of security of Cleaning for Outer Wall of Building operation seat-plate type ", the kind of drop device comprises now: bar type, 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 large when rope length is very long, sometimes even the problem of motionless rope occurs putting forward, brings very large trouble for construction and operation.In addition, unload the button drop device owing to there are some safety problems, do not advocated at present use.
Although bar type is very safe, in actual use, operating personnel's operation when descending is also very inconvenient; During use, operating personnel can lock drop device with the working rope free end in downslide rope mouth, working rope is untied from the rope mouth that glides then can be realized descending, but should note holding working rope downwards to prevent unexpected decline when untiing; Such operation has brought very large inconvenience to the user.Therefore, even also there is inconvenient problem in 8 word ring type drop devices in operation, people still are ready to select it.
Summary of the invention
There is inconvenient problem with use in order to solve the bar type drop device, the present invention proposes a kind of bar type drop device, combined by mandrel and outer sleeve, at outer sleeve the sliding rope mouth of outer sleeve is set, the pressure becket bridle also is set on outer sleeve, presses becket bridle under people's hand control, can do upper and lower sliding, when pressing becket bridle to be in sliding rope mouth position, the wiring on the mandrel is pushed, wiring frictional force increases, and human body stops to descend; When pressing becket bridle to move up to leave when gliding rope mouthful position wiring no longer compacted, wiring frictional force reduces, and human body descends.The drop device that the present invention proposes, the suspension attachment when not only can be used as the construction such as skin cleaning, finishing can also be as the building ' s fire lifesaving, speedily carry out rescue work or suspension attachment when high altitude rescue, operation the special equipment the when personnel that also can be used as drop from the air.
