Abstract
The utility model discloses an emergency escape extension ladder, comprising a box body, an extension ladder and a retracting mechanism. The extension ladder is a pipe-inserted type structure, the upper parts of two stand columns of the extension ladder are respectively fixed on the rear wall of the box body by pedestals, the retracting mechanism comprises a pulley and a retracting rope, the pulley is fixed together with the rear wall of the box body and is arranged in the middle of the two pedestals, the retracting rope cooperates with the pulley, the lower end of the retracting rope is fixed together with the center of a cross bar at the bottom end of the extension ladder. The emergency escape extension ladder has the advantages of realizing functions of linked opening and closing of upper and lower cover plates, slow extension of the extension ladder, extension ladder manual retracting, and so on, and finishing rapid evacuation and escape of large numbers of people in buildings under emergency situations, such as fire emergency accident. The ladder has the advantages of being simple in structure, artistic in appearance, safe and reliable, convenient to operate, strong in evacuation capability, wide in application range and long in service life, and so on.
Description
Technical field
The utility model relates to personnel escape's deliverance apparatus, particularly a kind of emergency escape extension ladder in the building.
Background technology
China builds the building that the scale of construction is big, the number of plies is many, personnel are intensive, combustible is many in a large number in recent years, in case burst fire in the building, the malignant fire accident that will certainly cause the dead group of group to hinder, serious harm public safety.Therefore the escape and evacuation of a large amount of personnel's quickly and orderlies in the building has become the problem that fire-fighting and implementation management department need solution badly.At present domestic except considering to use fire-fighting stairway to carry out the evacuating personnel when the architectural design, other devices that are used for the personnel escape often can not satisfy that number is many, speed is fast, safe, long service life, requirement such as easy to maintenance, various problems can take place in case use, can make the evacuation personnel face extremely dangerous condition, cause irremediable serious consequence.
My unit has applied for utility model patent " a kind of emergency escape extension ladder " (application number: 201220025778.4) in 2012.Find that through investigation because the structure difference of building, the space size that can be used for installing Emergency Ladder is also inequality.Therefore, we have developed the emergency escape extension ladder of different structure again.
The utility model content
The purpose of this utility model is at above-mentioned existing problems, provide a kind of simple in structure, can make personal security escape, evacuation speed emergency escape extension ladder fast, safe and reliable, convenient for installation and maintenance.
The technical solution of the utility model:
A kind of emergency escape extension ladder, comprise casing, extension ladder and recovering mechanism, it is characterized in that: extension ladder is the cannula type structure, the upper end of two root posts of extension ladder is fixed with the rear wall of casing respectively by bearing, recovering mechanism comprises pulley and reclaims rope, two bearing position intermediate are fixed and be arranged to the rear wall of pulley and casing, reclaims rope and cooperate with pulley, reclaims the lower end of rope and the cross bar center fixation of extension ladder bottom.
The course of work of the present utility model:
1) breaking out of fire etc. in emergency circumstances, the escape personnel opens stainless steel box cover plate, when upper cover plate is opened, by the effect of interlock pole, lower cover is together opened, extension ladder is owing to the effect vertical stretching of gravity, and till extension ladder was down to down the first floor plate, this moment, the escape personnel can evacuate by the downward one deck of extension ladder.
2) removal process: after finishing using, administrative staff pursue the closed cover plate up and down of joint withdrawal by pulley and recovery rope traction extension ladder from a bottom joint and get final product.
The utility model has the advantages that: this emergency escape extension ladder, can realize functions such as cover plate open-shut linkage, extension ladder slowly stretch up and down, the manual recovery of extension ladder, can finish in the building a large amount of personnel in rapid evacuation escapes in emergency circumstances such as burst fire incidents, this ladder is equipped with advantages such as compact conformation, good looking appearance, safe and reliable, simple operation, evacuation capacity are strong, applied range, long service life.
