Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-4, an external hanging folding slow-descent escape ladder comprises a top plate 1, an escape passage 2, a bottom plate (the bottom plate is not shown in the figures) and a cable, wherein the escape passage 2 is a flexible spiral semicircular slideway, the top plate 1 and the bottom plate 2 are respectively fixed at the top end and the bottom end of the escape passage, the top plate 1 is provided with an inlet 4 corresponding to the spiral semicircular slideway, and the bottom plate is provided with an outlet corresponding to the spiral semicircular slideway; the upper end of the top plate is provided with a handrail structure, and the handrail structure 10 is semicircular so that a person can hold the handrail to slide into the escape passage.
The hawser includes equidistant setting, along vertical outside protection hawser 6 and equidistant setting that is fixed in the spiral semicircle slide outside, along vertical inside protection hawser 7 that is fixed in the spiral semicircle slide inboard, under the expansion state, outside protection hawser 6 and inside protection hawser 7's top is fixed in roof 1 on, supports through the drawknot effect of outside protection hawser 6 and inside protection hawser 7 the passageway of fleing constitutes stable spiral semicircle slide. (in figures 1 and 4, the external protection cables 6 and the internal protection cables 7 are only intended to show the position and not the correct number, to express the structure clearly)
In order to enable a human body to slightly tilt inwards and avoid eversion of the human body and provide certain assistance of inward-rotation and downward-sliding, the vertical distance between each external protection cable 6 and the connection node of the escape channel 2 is smaller than the vertical distance between each internal protection cable 7 and the connection node of the escape channel 2, so that the spiral semicircular slide way slightly tilts inwards.
In order to improve the safety level of the escape passage 2, the horizontal distance between two adjacent external protection cables 6 is designed to be smaller than the horizontal distance between two adjacent internal protection cables 7, so that a dense cable wall can be built outside the slideway, and the functions of enclosing and providing safety guarantee are achieved.
In order to prevent the escape passage 2 from being broken, the main material of the spiral semicircular slideway is basalt fiber cloth; in order to prevent the cable from being broken, the cable is a basalt fiber composite cable, and the basalt fiber has extremely high tensile strength, so that the occurrence probability of abnormal conditions can be reduced.
In order to prevent rain erosion, a storage space 8 is provided below the top plate to store the folded escape passage and the cable.
In order to let the person who enters the escape way 2 rely on, the inner side of the escape way is provided with a flexible spiral handrail 9 matched with the escape way, the spiral handrail is fixed on the internal protection cable rope and can be held by hands to slowly descend.
The working principle is as follows: this equipment should adorn in advance in the building wall outside, the window outside at position or corridor both ends like the balcony, and fold and accomodate in the roof below, the backplate protection of roof below is got up, avoid receiving the long-term erosion of nature such as rainwater, unexpected condition takes place when conflagration, when needing to flee, the people goes up to the roof on, then loosen and tie the knot, escape way is flagging naturally under pulling of bottom plate, until the hawser straightens, the bottom plate of below is fixed by below rescue crowd, escape way natural shaping, then arrange the personnel of fleing and get into escape way one by one.
When entering, the handrail structure on the roof is held by hand earlier, the position and the entering angle of health have been adjusted, loosen the hand and get into in the passway for escaping, because be flexible passway for escaping, human gravity causes the resistance to the slip of passway for escaping, make it slightly warp, the decline resistance is great, the slide that inclines slightly this moment can assist human gravity to provide certain boosting power, and simultaneously, because the great problem of resistance, the falling speed is slow relatively, the people can hand the handrail of inboard, slowly descend, avoid descending too fast and produce centrifugal force, outwards throw away the people, the intensive hawser wall in the outside can provide certain guard action, guarantee personnel's of fleing safety.
The utility model is suitable for a building of lower floor, like the building on 5-7 floors, especially residential building, the cost is lower, and factor of safety is higher relatively.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
