Description

Novel bow-shaped outdoor escape ladder

Technical Field

The utility model relates to an emergency ladder technical field, in particular to novel outdoor emergency ladder of bow font.

Background

The space between the buildings of the 'hand shaking buildings' in the small workshops, the rental houses, the urban villages and the rural areas is narrow; most of the places have the structure that only one evacuation stair exists inside the building; once dangerous case occurs, a large disaster can be caused; therefore, generally, for these buildings, an escape ladder is installed on the outer wall of the building for emergency danger avoidance.

There are three common escape ladders: the first vertical ladder has the advantages of low manufacturing cost and small occupied outdoor space; but has the disadvantages that the higher the floor is, the higher the distance from the ground is, the higher the danger is generated by the escaper; the upper and lower straight-through type slide down easily causes the casualties; the whole bearing capacity is large, and the ladder is easy to fall off under the condition of a plurality of persons; the evacuation speed is slow.

Second, "Z" ladder: the advantages are that: the ladder has large bearing capacity and firm ladder body; the evacuation speed is high; the safety factor is high, the evacuated personnel have high fear and small psychological and fall-out probability; the disadvantages are as follows: the cost is high; the occupied space is relatively large compared with that of a vertical ladder, and the narrow space among the buildings is difficult to realize.

And thirdly, auxiliary equipment such as an escape opening, a rope ladder and a descent control device: the advantages are that: the configuration cost is low; the disadvantages are as follows: the evacuation of the rope ladder is relatively difficult for young men and children, old people and women can not climb the ladder at all; the rope ladder exceeding 3 layers is dare not to climb at all, and the risk of falling death is high; the evacuation efficiency is extremely low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel outdoor emergency ladder of bow font to prior art's defect with not enough.

In order to achieve the purpose, the utility model adopts the technical proposal that:

the utility model relates to a novel bow-shaped outdoor escape ladder, which comprises a plurality of platforms arranged along the height direction; crawling ladders are arranged between every two adjacent platforms; ladder entrance openings for entering a ladder below are formed in the positions, connected with the tops of the ladders, of the platforms; the adjacent two ladder inlets are arranged in a staggered manner.

Furthermore, a protective cover body is arranged on the ladder stand; the bottom of the shield body is provided with an outlet through which adults can pass.

Further, a guard rail is arranged on the edge of the top surface of the platform.

Furthermore, the bottom surface of the platform is provided with a support column fixed on the wall.

Further, the platform and a ladder stand above the platform are integrally formed.

Further, the crawling ladder and the platform are made of stainless steel materials through welding.

Furthermore, the crawling ladder and the wall body are obliquely arranged; the distance between the ladder stand and the wall body is the distance between the ladder stands and the wall body; the distance between the ladder walls is gradually increased from top to bottom along the height direction.

After the structure is adopted, the utility model discloses beneficial effect does: when the novel bow-shaped outdoor escape ladder is used, the ladder stand and the platform are both fixed on a wall body; and the wall body is provided with safety outlets at the positions of the platforms; the arrangement of cat ladder is the bow font and arranges, is the dislocation set between the cat ladder, reduces the fear of terrorist high escape person, reduces the weight loss risk of personnel, and this kind of cat ladder can arrange in constrictive space moreover, occupies littleer outdoor space.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the novel bow-shaped outdoor escape ladder of the present invention comprises a plurality of platforms 3 arranged along the height direction; a ladder stand 2 is arranged between every two adjacent platforms 3; the platform 3 is provided with ladder entrance openings 301 for entering the ladder 2 below at the positions connected with the tops of the ladders 2; the adjacent two ladder inlet ports 301 are arranged in a staggered manner; the ladder stand 2 and the platform 3 are both fixed on the wall 4; and the wall 4 is provided with a safety exit 401 at the position of the platform 3; the arrangement of cat ladder 2 is the bow font and arranges, is the dislocation set between cat ladder 2, reduces the fear of terrorism high escape person, reduces the weight loss risk of personnel, and this kind of cat ladder can arrange in constrictive space moreover, occupies littleer outdoor space.

As a preferred mode of the utility model, a protective cover body 1 is arranged on the ladder stand 2; the bottom of the shield body 1 is provided with an outlet 101 through which adults can pass; through the protection of the protective cover body 1, the ladder stand 2 is safer when in use.

As a preferred mode of the present invention, a guard rail 5 is disposed on the edge of the top surface of the platform 3; when the ladder stand is designed, the height between the top of the guard rail 5 and the top surface of the upper exit 101 cannot be more than 45cm, so that the evacuee is prevented from falling in the gap between the guard hood body 1 and the guard rail 5, and the safety of using the ladder stand is improved.

As a preferred mode of the present invention, the bottom surface of the platform 3 is provided with a supporting column 302 fixed on the wall 4; the support columns 302 are used to support the platform 3, making the platform 3 more stable.

As an optimized mode of the utility model, the platform 3 and the ladder 2 above the platform 3 are formed by integral forming.

As a preferred mode of the utility model, cat ladder 2 and platform 3 are stainless steel material and weld and form.

As shown in fig. 3, as a preferred mode of the present invention, the ladder 2 is disposed obliquely with respect to the wall 4; the distance between the ladder 2 and the wall 4 is the distance between the ladder and the wall; the distance between the ladder walls is gradually increased from top to bottom along the height direction; set up an angle through between cat ladder 2 and the wall body 4 for when crawling, can see the step of below, can make the flee personnel focus be close to cat ladder 2 more moreover, reinforcing security performance.

When the utility model is used, the crawling ladder and the platform are both fixed on the wall body; and the wall body is provided with safety outlets at the positions of the platforms; the arrangement of the crawling ladders is in a bow-shaped arrangement, the crawling ladders are arranged in a staggered manner, the fear of high-fear escapers is reduced, the risk of falling casualties is reduced, and the crawling ladders can be arranged in a narrow space and occupy smaller outdoor space; the ladder stand is provided with a protective guard body, and the height between the top of the protective guard and the top surface of the upper outlet cannot be more than 45cm during design, so that escape personnel can be prevented from falling in a gap between the protective guard body and the protective guard, and the use safety performance of the ladder stand is improved; through setting up an angle between cat ladder and the wall body for when crawling, can see the step of below, can make the flee personnel focus be closer to the cat ladder more moreover, reinforcing security performance

What has just been said above is the preferred embodiment of the present invention, so all according to the utility model discloses a patent application scope structure, characteristic and principle do equivalent change or modify, all include the utility model discloses a patent application scope.
