Open the Chinese patent net, high-rise life saving scheme miscellaneous is innumerable, but social obtain promoting the use of almost nil.

Patent Office of the People's Republic of China's application number is the high-building life-saving device of (01241103) notification number for (2471350), have the housing of cover plate and assemble its interior rope sheave and wire rope, wherein an end of rope sheave is fixed with ratchet, the ratchet that is meshed with ratchet is hinged on the pull bar of handle link rod control, and the handle end of cross-articulation is fixed with the friction plate that is coated on rope sheave dampened disk periphery mutually.

Patent Office of the People's Republic of China's application number is slow the fall machine of (200610153819) notification number for (1939556), and a kind of user of permission utilizes slow the fall machine of an escaping rope with its escape that descends, and has taked guide rod and hanger to be combined in the frame mode of tubular body.

Above patent structure complexity involves great expense, and is not easy to control, and mechanical damping does not have safety guarantee, is difficult to concrete enforcement.So, can not obtain society and generally promote.

With regard to the whole society, a kind of simple in structure, stable performance, be convenient to collect and use, cheap, real fire in high buildings escape equipment that can penetration and promotion also do not come out, treat that suddenly we go to explore, research.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of rope ring ladder of forming by applying mechanically cable wire in a plurality of cavity ring.

The present invention solves the above-mentioned technical problem of putting forward by the rope ring ladder that a kind of following structure is provided, and this rope ring ladder comprises: cavity ring, cable wire, steel ball, go out the rope hole, add sheet, spacer, go up whippletree, whippletree, anti-slide plate, hook are formed down.Described cable wire can be very firm will encircle with the ring between is connected, again can the ten minutes be concealed in respectively flexibly in the half arc pipe of adjacent two cavity ring.

Rope ring ladder of the present invention has following advantage:

1, simple in structure, stable performance: its stressed member has only cable wire, cavity ring and steel ball, if adopt stainless steel to make, it is stressed can say constant throughout one's life.Be not afraid of high temperature simultaneously, be not afraid of acute angle and cut off.

2, need not safeguard, frangibility not: its steel ball is to rotate in the cavity ring of half arc arbitrarily and to slide, and the length of cable wire is very short, arbitrarily loses, puts, and cable wire can not rolled over the sharp turn yet, kill knot.

3, applied widely: can be according to high the stressed of cavity ring and cable wire that design in different buildings; Simultaneously, can be used for the lifesaving of down-hole, steep cliff,, solve need many people up or downwards to pull the problem of object or person under hanging on or hanging because its pin is stepped on well, hand is grabbed well.

4, being convenient to collection also can link to each other by multistage: be longer than the cable wire of three times of cavity ring diameters, can shrink fully in two adjacent cavity ring half arcs, ring is very little near volume with ring, and quality is very light, is convenient to collect and carry; If consider the stressed problem of single group rope ring ladder, can be with the windowsill setting of whole the same correspondence of high building, thus realize that multistage links to each other.

5, cheap, be suitable for promoting: rope ring ladder is all cheaper than removing any lifesaving appliance cost of making by oneself the rope.And rope is compared with rope ring ladder, then have stressed little, be afraid of high temperature, a lot of problems such as easily rub, easily go rotten.

6, function wide coverage: there is rope ring ladder at a family, can manage many families safety downstairs.Because its each ring can be as fulcrum up and down.Even can also be from downstairs toward upthrow.

Description of drawings

Three embodiments of the present invention are described below with reference to accompanying drawings.

Fig. 1 is a single ring architecture schematic diagram of the present invention;

Fig. 2 is the schematic diagram after many rings of the present invention stretch;

Schematic diagram when Fig. 3 stacks for many rings of the present invention.

The specific embodiment

Fig. 1 and Fig. 2 show the concrete structure of monocycle in the rope ring ladder of the present invention: cavity ring 1 upper and lower have only be used for that cable wire 2 slides go out rope mouth 4, the firm respectively bundle in the two ends of cable wire 2 has on the steel ball 3 that can slide in hollow section 1, one end of the cable wire 3 of top is equipped with hook 10, and the sheet 6 that is positioned when steel ball 3 slips into to half arc blocks.The length of every joint cable wire 2 is about 3.14 times of cavity ring 1 diameter.Consider stressed effect, go out being welded with of rope mouth 4 on every side and add sheet 5.At whippletree 7 and following whippletree 8 in the welding respectively on the cavity ring 1, be out of shape when stressed to prevent cavity ring 1.Welding has faceted anti-slide plate 9 on following whippletree 8.The thickness of cavity ring 1, cable wire 2 is determined according to the height of floor and stressed size cases.
