Abstract
The utility model provides an emergency staircase for fire protection which can be used for replacing an emergency evacuation exit on the existing building. The utility model can realize that persons and articles can be transferred quickly after a fire hazard occurs through the emergency staircase which is attached on the building and can fall down in uniform speed by self weight. With the advantages of quick evacuation, light weight, high safety, low cost, etc., the utility model can be widely used in various industries and civil buildings.
Description
The utility model belongs to the fire-extinguishing and lifesaving device, particularly relates to a kind of building fire-fighting evacuation ladder.
Current, the building particularly fire precaution of high-rise mainly is to rely on the emergency evacuation stair.The emergency evacuation stair not only need take the floor area of building, and after fire took place, the influence of power failure and smog also made the evacuation effect bad.
The purpose of this utility model provides a kind of fire-fighting evacuation stair that replace the emergency evacuation passage on the existing structure, is applicable to the brand-new fire-fighting evacuation stair of various buildings.
The purpose of this utility model is to realize like this, adhere to building and make up a ladder (ladder can by concrete depositing), ladder and building join, two terraced rails are fixed on the ladder, the ladder seat is equidistantly connected by terraced chain and connection cord, and when the ladder seat had weight, the gravity control device on the ladder seat will change angle, with terraced rail join the friction slide, gravity is big more, and friction force is big more, and gravity and friction force are directly proportional, and motion can remain a constant speed, gear on the retardation controller and the interlock mutually of ladder seat chain when the ladder seat falls, begin to rotate, one gear is housed on the retardation controller, and the rotor of one group of permanent magnet is housed, spindle and coil are housed, on the housing when the gear on the controller main shaft rotates, the rotation of drive rotor produces electric power, and electric power can exist and be equipped with the use that has a power failure in the storage battery.
The utility model can be widely used in various industry, civil construction field, is a kind of comparatively ideal fire-fighting emergency evacuation stair and escape way, and it has evacuates advantages such as fast, in light weight, safe and reliable.
Below just be described further in conjunction with the accompanying drawings:
Fig. 1 is a side sectional view of the present utility model
Fig. 2 is a front schematic view of the present utility model
Fig. 3 is a principle of work scheme drawing of the present utility model
As shown in the figure, ladder 1 is attached on the building, and terraced rail 2 (two) be fixed on the ladder, and ladder seat 3 passes through gravity control device 6 and terraced chain 4, connection cord 5 (two) is equidistant fixes, and joins with terraced rail 2.Gravity control device 6 and terraced rail 2 interlocks produce resistance, ladder seat uniform descending.Retardation controller 7 (two) is individually fixed in the upper and lower of ladder 1, by gear and 4 interlocks of terraced chain, generating set 8 is housed on the gear.When down to ground, the ladder seat is located at ground-surface ladder support 9 and is carried on the back.After personnel leave the ladder seat, when in the upper class ladder seat weight being arranged, turn on the next stage ladder seat, reciprocal successively, circulate.
Claims (3)
1, a kind of deadweight control fire-fighting evacuation stair that constitute by ladder, terraced rail, ladder seat, terraced chain, generating set etc., it is characterized in that: on the ladder seat gravity control device is installed, gravity control device and terraced rail interlock, terraced rail is installed on the ladder, and ladder is attached on the building.
2, deadweight control fire-fighting evacuation stair as claimed in claim 1, it is characterized in that: the ladder seat equidistantly is installed on the terraced rail by gravity control device and ladder rope.
3, deadweight control fire-fighting evacuation stair as claimed in claim 1 is characterized in that: power generation assembly is housed on retardation controller.
