Abstract
The utility model discloses a steel wire anti-loose type speed regulating mechanism of a high-rise escaping self-help descent control device, and belongs to the field of machines. The steel wire anti-loose type speed regulating mechanism comprises an escaping rope, a machine frame, a gear, a rope pressing wheel, a rope pressing wheel shaft, a speed regulating sleeve, a speed regulating rod, a screw, a steel wire rope and fixing screws. The gear is assembled on the machine frame through a shaft, the machine frame is provided with a U-shaped groove, the rope pressing wheel shaft is assembled in the U-shaped groove of the machine frame, the rope pressing wheel is embedded in the rope pressing wheel shaft, the escaping rope penetrates through the gap between the gear and the rope pressing wheel, the top end of the speed regulating rod is provided with a through hole, the steel wire rope penetrates through the through hole in the top end of the speed regulating rod, and the two ends of the steel wire rope are fixed to the speed regulating sleeve through the fixing screws. The steel wire anti-loose type speed regulating mechanism solves the problems that an existing high-rise escaping self-help descent control device is not prone to speed regulation and is prone to getting loose, and the steel wire anti-loose type speed regulating mechanism has the advantages of being simple in structure, reasonable in design and easy to manufacture.
Description
Technical field
The utility model relates to a kind of speed adjusting gear, more particularly, relates to a kind of self-service descending lifeline speed adjusting gear of steel wire anti-loosing type high-rise life saving for the self-service descending lifeline speed governing of high-rise life saving.
Background technology
Along with the development of modern architecture technology, architecture storey is more and more higher, once the emergencies such as breaking out of fire cannot be escaped because passage is blocked by big fire.Conventional is safe escape stair at present, but safe escape stair escape speed is slow, and owing to producing a large amount of cigarettes in fire, causes people to suffocate in escape process, and escape also exists the problem of trampling in addition.And adopt descending lifeline can make people fast from high-rise life saving, avoid the generation of above-mentioned event.
Part fall-slowing device for rescuing from high building is to drive braked wheel to rotate by escaping rope at present, utilizes the braking of braked wheel is realized to reduction of speed, and reach the object of speed governing by controlling braked wheel and rope pressure.But because the pressure between escaping rope and braked wheel should not be controlled, and cause speed governing to be difficult for, and in use often there will be pressure to change, so there will be potential safety hazard.Simultaneously, due to when the specific works, because escaping rope long duration of action is in braked wheel, easily cause loosening.
Utility model content
Speed adjusting gear speed governing for the self-service descending lifeline of existing high-rise life saving is difficult for, easily occurs that loosening problem, the utility model provide a kind of steel wire anti-loosing type high-rise life saving self-service descending lifeline speed adjusting gear.
For addressing the above problem, the utility model adopts following technical scheme.
The self-service descending lifeline speed adjusting gear of a kind of steel wire anti-loosing type high-rise life saving, comprise escaping rope, frame, gear, press rope wheel, press rope wheel axle, speed governing cover, speed control rod, screw, steel wire rope, hold-down screw, described gear is assemblied in frame by axle, described upper rack is provided with U-shaped groove, described press rope wheel axle is assemblied in the U-shaped groove of frame, described press rope wheel is nested on press rope wheel axle, the gap of described escaping rope through gear and press rope wheel, described speed governing cover is fixed by screws in frame, described speed control rod is fixed in speed governing cover, described speed control rod top is provided with through hole, the through hole on described steel wire penetrating speed control rod top, steel wire rope two ends are fixed on speed governing by hold-down screw and put.
The quantity of described speed control rod is 2, and is arranged symmetrically with.On described speed control rod, be provided with screw thread and be fixed on by screw thread in the screwed hole of speed governing cover.Described steel wire rope is made up of mild steel wire.
Than prior art, the beneficial effects of the utility model are:
(1) the utility model changes the gap length of press rope wheel and gear by adjusting speed control rod, thereby changes the pressure between escaping rope and gear and press rope wheel, reaches speed governing object.
(2) the utility model utilization steel wire rope of connecting on nut is realized the locking of adjusting rod, locking simple and reliable.
(3) the utility model is simple in structure, reasonable in design, is easy to manufacture.
