Description
Technical field
The present invention relates to lifesaving appliance technical field, more particularly to a kind of Emergency Ladder.
Background technology
Currently, often using Emergency Ladder in places such as fire disaster escaping, height rescue and working at height, especially escape in fire
In life, Emergency Ladder plays a crucial role.But found in actual use, existing Emergency Ladder is lacked there are following
Point：1, existing Emergency Ladder overall weight is heavier, needs to use longer Emergency Ladder when high-storey is rescued, and it is inconvenient to carry.
2, the Emergency Ladder of existing terraced rope structure is readily ignited, flame retardant property is bad, influences to use at high temperature when fire occurs
Safety.What 3, existing Emergency Ladder easy needs of shaking back and forth in outdoor application were artificial, which pull, prevents from shaking, and increases
Manpower, it is inconvenient for use.4, the step stool of existing Emergency Ladder uses columned structure, is easy to skid, influence safe to use.
Invention content
To solve the shortcomings of the prior art, present invention offer one kind is light-weight, stability is good, safe to use, fire-retardant
Emergency Ladder.
The technical scheme is that：
A kind of Emergency Ladder, including Emergency Ladder ontology, the Emergency Ladder ontology include at least two ladder ropes being mutually parallel, wear
Cross several step stools for being mutually parallel vertical with terraced rope that ladder rope is fixed on by fixing device on ladder rope, the step stool setting
For the rectangular parallelepiped structure of inner hollow both ends open, the step stool is provided at both ends with the perforation that may pass through ladder rope, the perforation
Set at least to 2；The top of the ladder rope is provided with 1 the first ring eye, and setting is at 4th reciprocal and reciprocal in the step stool
It is provided with 1 the second ring eye on ladder rope between 5th step stool, extension is respectively arranged on first ring eye and the second ring eye
Hook；The fixing device include be fixed on ladder rope on be set in step stool the first fixing device, be fixed on ladder rope on be set to
Second fixing device of step stool lower end and the locking gasket being arranged between step stool and the second fixing device.
Further, first ring eye and the second ring eye are woven by the way that ladder rope is interspersed, first ring eye
The bottom end of second ring eye is provided with metal fixing buckle.
Further, the ladder rope include wire rope core made of being compiled by 50-60 strands are double and be coated on outside wire rope core by 18-20
Fireproof wear-resisting layer made of the double volumes of strand.
Further, the wire rope core is made of p-aramid fiber long filament, and the fireproof wear-resisting layer is by p-aramid fiber long filament, poly-
Imide fiber, glass fibre are made, p-aramid fiber long filament in the fireproof wear-resisting layer, polyimide fiber, glass fibre
Quantity ratio is 8:1:1.
Further, the step stool is made of glass fiber compound material, and the anti-skidding of strip is provided on the step stool
Protrusion.
Further, the length × width × height of the step stool is set as 33cm × 5cm × 3cm.
Further, first fixing device is set as the rubber column of inner hollow both ends open, and described second fixes
Device is set as metal fixing buckle.
Further, the weaving method of the ladder rope includes the following steps：
(1) inner core is woven：Threads are first twisted more stocks, more stocks is woven together, inner core is made；
(2) fireproof wear-resisting layer is woven：More different yarns are first woven into more stocks according to quantity ratio, by what is be woven into
More stocks are woven centered on inner core；
(3) braiding of ring eye：The top for the ladder rope being woven into step (2) is inserted by interspersed device on ladder rope and is formed
First ring eye continues the second ring eye of interspersed formation after forming the first ring eye.
Further, fireproof wear-resisting layer coats aluminium oxide and transparent ring in knitting forming rear surface in the step (2)
Oxygen resin compounded coating.
What the present invention was reached has the beneficial effect that：
The terraced fireproof wear-resisting layer for including wire rope core and being coated on outside wire rope core of restricting of Emergency Ladder in the present invention, the wire rope core being woven into
The intensity of ladder rope is increased, the fireproof wear-resisting layer being coated on outside wire rope core has the effect of fire-retardant, avoids the mistake in fire disaster escaping
It is ignited in journey, use is safer.
The first ring eye and the second ring eye is arranged on ladder rope in the Emergency Ladder of the present invention, and in the first ring eye and the second ring eye
On be both provided with hook, during specific use, the hook first passed through on the first ring eye fixes Emergency Ladder, is passing through
During Emergency Ladder is escaped, can the second ring eye be subjected to secondary fixation by the hook being arranged on ring eye, subtracted significantly
The shaking for having lacked Emergency Ladder facilitates the use of follow-up personnel, need not also increase manpower Emergency Ladder to be fixed.
The ladder rope ship of the present invention crosses the perforation at step stool both ends, is fixed by fixing device, simple in structure, stability
By force, traditional design that cross bar or supporting rope are set among step stool has been broken, has reduced the weight of Emergency Ladder entirety, improve
Production efficiency.To further decrease the overall weight of Emergency Ladder, the material of the step stool uses glass fibre composite.
The structure setting of step stool is rectangular parallelepiped structure by the present invention, and the anti-skidding convex of strip is provided on step stool
It rises, it is safe to use, conveniently trample.
