Abstract

The utility model relates to an emergent escaping device for landing and evacuating emergent people from a high building, which comprises a landing mechanism body with a suspending hook on the top, a rope tying component and a landing rope installed in the landing mechanism body. The rope tying component is a transverse rod fixed in the landing mechanism body; the landing rope is a closed loop rope; the upper part of the closed loop rope winds towards the upper part of the transverse rod and the lower part can be close to a safe place for landing and evacuating. The utility model has the advantages of simple structure, high safety, rapid and repeated use, low manufacture cost and convenient operation, and the utility model is suitable for various kinds of people to use.

Description

The emergency escape device

The utility model relates to a kind of emergency escape device that the high building emergency worker descends and withdraws under fire emergency.

In the prior art, Lifesaving device has lifesaving descent control device, safety rope etc.The rope system that planetary mechanism is housed in the decline mechanism body of lifesaving descent control device connects member, utilizes the centrifugal friction of planetary mechanism and brake pad to slow down the rope decrease speed.Because it uses single decline rope, if brake pad breaks down, consequence is hardly imaginable; Its structure is also complicated, poor reliability, moreover round serviceability is poor, many person-times of service times are long.The use of single safety rope is only limited to two, three layers building, because of it does not have other corollary equipment, only firmly grasps rope by the escape people's that descends strength itself and descends, and requires the user strong, and therefore the people who is suitable for is few.

The purpose of this utility model is to provide a kind of more reliable, simple and easy, practical, emergency escape device that can be reciprocal fast, is suitable for the personnel at all levels and uses.

For achieving the above object, the utility model adopts following proposal: the utility model is the same with prior art to include decline mechanism body that a top has hanged hook, be installed on rope system company's member and decline rope in the decline mechanism body.It is characterized in that it is a cross bar that is fixed in the decline mechanism body that rope system connects member; The decline rope is a closed loop rope, and curl up on cross bar on closed loop rope top, and place of safety can be withdrawn near descending in closed loop rope bottom.During use, the decline mechanism body is hung on the reliable thing of building eminence by the hanged hook at top, fall in outside the building under the decline rope, the end user fastens health on a sagging rope of closed loop rope, and both hands are firmly grasped the sagging rope of another root of closed loop rope, loosen sagging rope in the hand by hand lentamente, because the frictional force between rope and cross bar and rope and the rope, can realize slowly easily descending, its decrease speed can be regulated by the speed that the hand grip rope of end user own discharges, and also can put the survivor by a sagging rope of the two pulling closed loop rope and descend.When the former dropped to place of safety, second survivor escape that can then descend realized back and forth using fast.

The closed loop rope that curls up on the above-mentioned cross bar can contact with decline mechanism body top inner wall, can prevent then that rope from curling up on cross bar takes place that rope is overlapping to be curled up, can make the friction of rope and decline mechanism body top inner wall again and increase the decline resistance, use more laborsaving.

Above-mentioned cross bar can be designed to the spirality bar, and curl up in the helicla flute of spirality bar on closed loop rope top.Friction between rope and the helicla flute provides the decline resistance.

Use in order to be more convenient for, at fixedly connected two hooks of the middle part of closed loop rope symmetry or link.The end user can be hung on the safety door hook of safety belt on one's body on a hook or the link and promptly fasten with a sagging rope of closed loop rope.

Above-mentioned decline mechanism body can be designed as " ∩ " shape framework or the casket body of wire rope handling opening is arranged for the bottom.

The utility model compared with prior art, have following conspicuous advantage: the utility model is simple in structure, and is safe and reliable, can be fast, back and forth use, low cost of manufacture, easy to use, be suitable for the personnel at all levels and use, thereby be convenient to promote.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the structural representation (omitting the lower middle portion of closed loop rope) of another embodiment of the utility model.

Fig. 3 is the structural representation (omitting the lower middle portion of closed loop rope) of the 3rd embodiment of the utility model.

An optimum implementation of the present utility model is: referring to Fig. 1, this emergency escape device includes decline mechanism body 1 that a top has hanged hook 2, be fixed in cross bar 3 and decline rope 4 in the decline mechanism body 1.Cross bar 3 is the spirality bar, and decline rope 4 is the closed loop rope, and curl up in the helicla flute of spirality bar 3 on closed loop rope 4 tops, and place of safety can be withdrawn near descending in closed loop rope 4 bottoms, fixedly connected two

links

5,6 of closed loop rope 4 middle parts symmetry.The weight of bearing of closed loop rope 4 is designed to 1.4～1.5 tons.Decline mechanism body 1 is the casket body of two lacing holes of going to the bottom.

Fig. 2 illustrates another embodiment of the present utility model, and present embodiment and the foregoing description are basic identical, and institute's difference is that cross bar 3 is cylindrical polished rod, and closed loop rope 4 tops are curled up on cross bar 3 and contacted with decline mechanism body 1 top inner wall.

Fig. 3 illustrates the 3rd embodiment of the present utility model, and present embodiment and first embodiment are basic identical, and institute's difference is a cross bar 3 for there is the cylindrical polished rod of bulge loop at both ends, and curl up on the cylindrical polished rod between 3 liang of bulge loops of cross bar on closed loop rope 4 tops.
