Problems solved by technology

However, in actual use, it is found that the existing escape ladders have the following disadvantages: 1. The overall weight of the existing escape ladders is relatively heavy, and it is necessary to use a longer escape ladder when a high floor is rescued, which is inconvenient to carry
2. The existing escape ladder with ladder rope structure is easy to be ignited at high temperature in case of fire, and its flame retardant performance is not good, which affects the safety of use
3. The existing escape ladder is easy to shake back and forth when it is used outdoors, and it needs to be pulled artificially to prevent shaking, which increases manpower and is inconvenient to use
4. The step stool of the existing escape ladder adopts a cylindrical structure, which is easy to slip and affects the safety of use

Embodiment 1

[0030] Such as Figure 1-4 As shown, an escape ladder includes an escape ladder body, and the escape ladder body includes two ladder ropes 2 parallel to each other, several ladder ropes 2 perpendicular to the ladder rope 2 passing through the ladder rope 2 and fixed on the ladder rope 2 by a fixing device. Step stools 3 parallel to each other. The step stool 3 is arranged as a hollow cuboid structure with openings at both ends, and two ends of the step stool 3 are provided with perforations that can pass through the ladder rope 2, and the number of perforations is two. The step stool 3 is made of glass fiber composite material. The step stool 3 is provided with strip-shaped anti-slip protrusions. The length×width×height of the step stool 3 is set to 33cm×5cm×3cm.

[0031] The top end of the ladder rope 2 is provided with a first ring eye 1, and the ladder rope 2 between the penultimate 4th and penultimate 5th ladder 3 in the ladder 3 is provided with a second eye. Eyelets 4,...

Abstract

The invention relates to the technical field of lifesaving equipment, in particular to an escape ladder. The escape ladder comprises an escape ladder body; the escape ladder body comprises two or moremutually-parallel ladder ropes, and a plurality of mutually-parallel ladder stools which penetrate through the ladder ropes to be fixed to the ladder ropes through fixing devices and are perpendicular to the ladder ropes; each ladder stool is of a cuboid structure with the hollow interior and the two open ends; two or more penetrating holes which can penetrate through the corresponding ladder rope are formed in the two ends of each ladder stool; a first ring opening is formed in the top end of each ladder rope; a second ring opening is formed in the position, on the ladder rope arranged between the fourth ladder stool from the bottom and the fifth ladder stool from the bottom, in the ladder stools; and hanging hoops are arranged on the first ring opening and the second ring opening correspondingly. The escape ladder is small in weight, good in stability, safe in use and excellent in flame retardant performance and suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of lifesaving equipment, in particular to an escape ladder. Background technique [0002] At present, escape ladders are often used in places such as fire escape, high-altitude rescue and high-altitude operations, especially in fire escapes, where escape ladders play a vital role. However, it has been found in actual use that existing escape ladders have the following disadvantages: 1. The overall weight of existing escape ladders is relatively heavy, and long escape ladders need to be used when high floors are rescued, which is inconvenient to carry. 2. The existing escape ladder with ladder rope structure is easy to be ignited at high temperature when a fire breaks out, and its flame retardant performance is not good, which affects the safety of use. 3. The existing escape ladder is easy to shake back and forth when it is used outdoors, and it needs to be pulled artificially to prevent shaking, which incr...
