Abstract

The utility model relates to a lifeline which belongs to the technical field of saving life in condition of a fire disaster, or a leakage of chemical toxic gas, etc. in a high building or a high industrial facility. The lifeline has the advantages of quickness, safety, reliable life saving process, lightness, simplicity, and convenience that are required in the conditions of saving life. The lifeline has a structure that a ladder 2 which is made of wire ropes is fixedly hooked on a fixed object inside the building; each of two ladder legs respectively passes through each of two pipe holes of a slider 4; a fire protection safety belt is tied on a user, and a safety hook on the safety belt is fixedly hung on a hanging hole of the slider 4. Since the slider 4 is prevented by a cross beam 3 of the ladder from falling down, the user is hung in the air. When the user operates a pair of scissors 7 on the slider 4 to cut off the cross beam 3 of the ladder, the user can descend towards the ground together with the slider.

Description

Life line

The utility model relates to the fire-extinguishing and lifesaving device of using on a kind of skyscraper.When high building or tall and big industrial plants in case during huge disasters such as big fire occurs, chemical gas, it is outdoor that top numerous residents, staff can be used for running away to rapidly from the eminence door and window, reduces to ground and escape danger.

Used rope ladder is to constitute with bundling some crossbeams between two ropes at present, and volume is big, weight is big, and the people down climbs on this kind rope ladder, needs very great strength and courage.Speed is very slow, and the people does not link to each other with ladder, and common people are with bad, in case accidentally drop in the high-altitude fixed can injures and deaths, so use not extensive.

Along with expanding economy, building is more and more, builds higher and higher, and upstairs electric wire such as net, gas piping are in length and breadth.Whenever fire alarm burst, the short time is sea of flame, and upstairs resident or the person in distress that working feel simply helpless.Therefore need protect their life security for they develop a kind of reliable lifesaving appliance.

The purpose of this utility model just provides a kind of life line.The people links to each other with life line, and the people can let both hands go in the air at height.The people aloft stops, the reduction of speed degree is random, own manually grasp, and lifesaving is not highly limit, and does not need power.Light simple, it is reliable to be perfectly safe, and cost is lower, extensive use when being fit to the grand building emergency lifesaving.

The purpose of this utility model is achieved in that on the rope hole of hook, is connecting two ladder legs of steel wire rope ladder.These two steel wire rope ladder legs, run through to get off in two steel pipes from the slide block respectively from top to bottom, then below slide block every 100 millimeters ladder crossbeams that have steel cable to make, firmly fix together with two ladder legs respectively with the two ends of strap-on structure, constitute a steel wire rope ladder steel wire rope ladder crossbeam.Between two steel pipes of slide block, top is welded and fused two steel pipes with a steel plate.A safety belt suppending hole is arranged on this steel plate.A scissors is arranged at the bottom between these two steel pipes, and the scissors shaft two ends are welded in respectively on the tube wall between two steel pipes, and two shear shanks are in the both sides of ladder crossbeam respectively.The person in distress will link up with the fixed position that firmly is hooked in high-rise building, and the high-altitude safe band that common fire-fighting is used ties up on one's body, and fire-fighting is hung over the safety door hook on the safety belt in the suppending hole of slide block, at this moment life line will be put into outdoorly, and oneself also runs away to outdoor.This moment, slide block can not glide along ladder leg, so the person in distress who hangs on the slide block is parked in motionless in the air because there is the ladder crossbeam to stop.When the person in distress cuts off the ladder crossbeam one by one with the scissors on the slide block, slide block then glides along two ladder legs.Because the steel pipe aperture of slide block is far longer than steel wire rope ladder leg and two wirerope diameter sums of ladder crossbeam.So under the gravity effect, the person in distress is just landed along two steel wire rope ladder legs earthward with slide block.This has just realized the purpose of lifesaving.The basic principle of this life line is: two ropes that hanging from above, after longitudinally fusing from top to bottom, the object that rides between two ropes can not descend voluntarily, in case when two ropes are separated from top to bottom gradually, ride over two objects between the rope under the gravity effect, along with separately descending gradually of two ropes.

Owing to adopt such scheme, the people links to each other with life line, and the people can let both hands go in the air at height, and it is reliable to be perfectly safe, without power, the people aloft stops, the reduction of speed degree is random, own manually grasp, and lifesaving is not highly limit, light simple, the long-term storage performance is constant, does not need frequent maintaining, low, the extensive use when being fit to the grand building emergency lifesaving of cost.

Below in conjunction with accompanying drawing the utility model is further specified.

Among the figure: 1 hook, 2 steel wire rope ladders, 3 ladder crossbeams, 4 slide blocks, 5 steel plates, 6 scissors shafts, 7 scissors, 8 suppending holes, L steel wire rope ladder length.

In the accompanying drawings, on the rope hole of hook 1, connecting two ladder legs of steel wire rope ladder 2.These two steel wire rope ladder legs, run through to get off in two steel pipes from the slide block 4 respectively from top to bottom, then below slide block 4 every 100 millimeters ladder crossbeams 3 that have steel cable to make, firmly fix together with two ladder legs respectively with the two ends of strap-on structure, constitute steel wire rope ladder 2 steel wire rope ladder crossbeam 3.Between two steel pipes of slide block 4, top is welded and fused two steel pipes with steel plate 5.A suppending hole 8 is arranged on steel plate 5, and a scissors 7 is arranged at the bottom between these two steel pipes, and the two ends of scissors shaft 6 are welded in respectively on the tube wall between two steel pipes.Two shear shanks are in the both sides of ladder crossbeam 3 respectively.The person in distress will link up with 1 and firmly be hooked in after the fixed position of high-rise building, the high-altitude safe band that common fire-fighting is used ties up on one's body again, and fire-fighting hung over the safety door hook on the safety belt in the suppending hole 8 of slide block 4, at this moment just life line is put into outdoorly, oneself also runs away to outdoor.This moment, slide block 4 can not glide along ladder leg, so the person in distress who hangs on the slide block 4 is parked in motionless in the air because there is ladder crossbeam 3 to stop.When the person in distress cuts off ladder crossbeam 3 one by one with scissors 7,4 of slide blocks glide along two ladder legs.Because the steel pipe aperture of slide block 4 is far longer than steel wire rope ladder leg and 3 two wirerope diameter sums of ladder crossbeam.So under the gravity effect, the person in distress is just landed along two steel wire rope ladder legs earthward with slide block 4.This has just realized the purpose of lifesaving.

L is the length of steel wire rope ladder among the figure, and it highly determines according to recovering, 200 kilograms of this life line maximum authorized payloads, and its safety coefficient equals 3.
