Description

Technical Field

[0001] The utility model relates to an escape ladder, in particular to an industrial fire escape ladder. Background Art

[0002] Industrial fire escape ladder is an emergency escape device designed for industrial sites such as factories and warehouses. Its main purpose is to help workers quickly and safely evacuate from high places to safe areas in the event of fire, explosion or other emergencies. Fire escape ladders are usually installed on the exterior walls or stairwells of buildings and are used independently in the event of power outages. They provide a reliable escape route for employees in industrial sites and effectively reduce casualties and property losses caused by fire accidents.

[0003] The structure of existing industrial fire escape ladders usually includes ladders, handrails, platforms, safety guardrails and other components. The ladder is the main part of the escape ladder and has sufficient load-bearing capacity and stability. The handrails are set on both sides of the ladder to facilitate the staff's hand grip and provide additional support. The platform is located at the top of the ladder or the second to last floor, allowing people to rest or wait for rescue when escaping. The safety guardrail surrounds the platform to prevent people from falling from a height.

[0004] However, the existing industrial fire escape ladders take up too much space when not in use, and the design of the escape ladder is not reasonable. For example, the slope of the ladder is too steep and the handrails are not properly positioned, which may cause additional difficulties for workers when escaping. Therefore, it is necessary to comprehensively consider the above issues to ensure that the equipment escape ladder can play its due role at critical moments and save space when not in use.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-3 The industrial fire escape ladder shown comprises:

[0025] The first ladder body 100 includes first side bars 110 on both sides forming inclined supports and a first cross bar 120 placed horizontally between the first side bars 110 to provide bearing capacity. The first side bars 110 on each side are connected to each other through a cross section 111 and an oblique section 112. The ends of the cross section 111 have mounting points. The mounting points of the cross sections 111 on both sides of the first ladder body 100 are hinged with connecting plates 700. The connecting plates 700 can be fixed to the top surface of the building by welding or using expansion bolts.

[0026] The support arms 200 are mounted on the first side bars 110 on both sides of the first ladder body 100, extending toward the wall and abutting against the wall to ensure the firm support of the industrial fire escape ladder;

[0027] The second ladder body 300 includes second side bars 310 on both sides and a second cross bar 320 disposed transversely between the second side bars 310. The second ladder body 300 is hinged to one end of the first ladder body 100. The hinge point is located beside the first ladder body 100 and the second ladder body 300. When the industrial fire escape ladder is deployed, the ends of the first ladder body 100 and the second ladder body 300 abut against each other.

[0028] The rescue platform 400 is installed at the lower part of the second ladder body 300 and extends outward laterally to provide a safe platform for people who want to escape after climbing the ladder;

[0029] The handrails 500 extend outward from the second side bars 310 on both sides of the second ladder body 300 and are located above the lifesaving platform 400, so that people can grab the handrails for support.

[0030] An end handle 600 extends outward from the connection point between the transverse portion 111 and the oblique portion 112 of the first side bar 110 . The end handle 600 and the oblique portion 112 are perpendicular to each other, which is also convenient for people to hold the handrail for support.

[0031] An L-shaped end plate 113 is extended outwardly from the side of the first side bar 110 at the lower end of the first ladder body, and a straight plate 311 is extended outwardly from the side of the second side bar 310 at the upper end of the second ladder body. The straight plate 311 is hinged on the L-shaped end plate 113.

[0032] In this embodiment, the industrial fire escape ladder is foldable. During initial installation, the connecting plate 700 is fixed to the top surface of the building, and the lifesaving platform 400 and the second ladder body 300 are retracted inwardly, parallel to the second crossbar 320, and the handrail and the lifesaving platform are crossed with the first ladder body on the outside to form a complete folding, supported on the wall by the support arm 200, and the folded first ladder body 100 and the second ladder body 300 can be fixed with adhesive tape, and the whole ladder is folded into a portable and compact shape. When it is necessary to unfold, open the adhesive tape, and the second ladder body 300 below, the first ladder body 100 and the second ladder body 300 form an inclined angle design, in order to increase the stability and carrying capacity of the industrial fire escape ladder and provide a safer escape environment. By tilting, the center of gravity position will shift to the lower part of the ladder, and the lower the center of gravity, the more stable the ladder. The tilt angle can increase the carrying capacity of the ladder by distributing the gravity load to the supporting structure. Through the tilt angle, the gravity force will be more vertically transmitted to the supporting structure, reducing the load on the ladder structure and better dispersing and supporting the weight of the ladder. The tilt angle can also provide a safer ladder climbing environment, especially in emergency situations such as industrial fire escape. The tilt angle can make the escapee more comfortable and stable when climbing, reducing unsafe factors that may occur in emergencies, such as falling, slipping or losing balance.

[0033] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
