Oilless bearing is installed to avoid the dry friction produced between part, it is ensured that the service life of part.
The utility model descending lifeline is using the i.e. fixed ring gear of NGW types planetary gear transmission, and steel wire rope is by being oriented to
Rope sheave is formed integrally across being wound in the race of rope sheave by wheel with planet carrier, and ring gear is formed integrally with shell.Pull steel wire
Rope, driving wheel is moved in the same direction by stiction with steel wire rope, and gear, gear and central gear and gear ring are provided with driving wheel
Engage simultaneously so that gear not only revolve round the sun by rotation again, by central gear with get rid of wheel and transmit the force to brake pad, the friction of brake pad
Face is located on gear ring, and four brake pads are uniformly distributed along central gear circumferential direction, it is rotated together with wheel is got rid of, and can be
Get rid of and move radially and radially throw away on wheel, produce force of sliding friction with the rubbing surface of gear ring, brake force is formed, so that automatically
Decrease speed is adjusted, uniform descent is realized, it is ensured that feels when people lands without impact and the course of work is without idle running.The descending lifeline is used
Fiber protects Aviation Steel Wire Rope.
The structure composition and dimensions of the utility model descending lifeline：The descending lifeline is main by speed regulator, rope sheave, safety
Band, safety door hook, Aviation Steel Wire Rope etc. are constituted.Metalwork smooth outer surface, non-corroding, spot, burr are simultaneously carried out at antirust
Reason.Cord end is wrapped up using protection pipe.Each part connection is reliable, the anomaly such as no deformation, damage.
（1）Critical piece and parameter：Rope：Aviation Steel Wire Rope rope outer surface is without wear phenomenon, a diameter of φ 8.0mm,
Built-in wirerope diameter is that φ 4.0mm structures are 6X19+IWS metals stock core rope, and material meets YB/T's 5197-2005
It is required that.
Safety belt：Material is terylene.Bandwidth 50mm, tape thickness 2mm, belt length 1100-1800mm, with user's chest can be pressed
Enclose the clasp that size adjusts length.Safety door hook：Stainless steel 304 safety door hook has safeties.Rope reel material uses poly- third
Vinyl plastics.Product casing：Mainboard, panel are aluminum casting, and integral surface is using the processing of electrostatic plastic-spraying.
Gear：Gear material is No. 45 steel, the zinc-plated processing in surface.Ring gear：Material is steel-casting（No. 45 steel）, at plating nickel on surface
Reason.Get rid of wheel：Material is No. 45 steel, the zinc-plated processing in surface.Brake pad：It is manufactured by POM injections, friction coefficient mu >=
0.48。
（2）Decrease speed is calculated：Here we are by taking 100kg people's weight as an example.Tangential force suffered by known main wheel
FT main wheels =G=100kgX9.8N/kg=980N。
According to《Mechanical handbook》Table 14-5-14 checks in tangential force suffered by NGW central gears for FT centers =1/2FT main wheels =
1/2x980=490N。
Known α is that pressure angle takes 20 °, NGW central gear force in radial FR centers =FT centers tanα=490tan20 °
=178.35N。
Cause brake pad to move radially and radially throw away due to getting rid of wheel rotation, and contacted with gear ring inwall, produce cunning
Known to kinetic force of friction f：Brake pad pressure：N=FR centers =178.35N f Brake pad =μN=0.48x178.35=85.61N。
Centripetal force during brake pad working condition：Fr=FR centers -f Brake pad =178.35-85.61=92.74N。
It can be calculated：Brake pad quality m=M gets rid of iron+M brake ribbons=0.049kg.
It is known：Driving wheel radius r1=35mm=0.035m；Get rid of wheel radius r2：43mm=0.043m.
Fr=mrω2 2, NGW central gears：ω2=(Fr/mr2)0.5=(92.74N/0.049kgx0.043m)0.5=2
09.8rad/s。
According to《Mechanical handbook》Table 14-5-2 is checked in：NGW gear ratios i=1/ (1+ZGear ring /Z Central gear )=1/
（1+39/9）=9/48 therefore NGW driving wheels ω1=ω2X i=209.8x9/48=39.33rad/s active wheel speeds：V=ω1r1=39.33rad/s x 0.035m =1.38m/s。
Decrease speed when V is peak load 100kg can similarly be obtained：
Decrease speed V=1.11m/ during decrease speed V=0.815m/s gauge load 65kg during minimum load 35kg
Descending lifeline is hung on test height by the 4.5.1 bars technical requirements that s meets GA413-2003, and then it is applied respectively
Plus minimum load, gauge load, peak load as defined in table 1, it is each to carry out decrease speed experiment, the decline of descending lifeline twice
Speed all should be between the m/s of 0.16m/s ~ 1.5.
。
The deceleration device that the planetary gear reducer structure that this product is used is combined with frictional damping, counteracts gravity and adds
Speed, has reached decrease speed even, the effect without idle running.Product safety is reliable, service life is long；Flexibly, be applicable and
It is simple to operate；Setting height(from bottom) is unrestricted, easy to carry, can back and forth use, and many people, extensive use are succoured in a short time
In office building, office building, public place of entertainment, hospital, school's contour level building place, it is both the escape equipment of trapped personnel, is again
The product of rescue, the indispensability of fire-fighting equipment.
When escaping descent control device of the present utility model is to occur accident in prevention building, one kind can allow personnel
With rope from high-rise interior to outdoor slow decline, the optimal escape apparatus for making trapped personnel escape danger rapidly.This product economy is real
With, it is easy to carry, many people can be succoured in a short time with Reusability.Work as high-rise building with fire disaster, fire-fighting and rescue officers and men are not
Rush to or aerial ladder insufficient height situation when, dense smoke raging fire encloses fire escape, and trapped personnel can be fast safely using this product
Fast voluntarily escape danger, and the passive situation of fire-fighting and rescue can only be relied in the past by thoroughly changing.This product not electricity consumption, not by external force,
Deadweight only by people can work, and automatically adjust decrease speed according to the body weight of people.This product is easy to operate, without special instruction
Practice, men and women, old and young can be used.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
