The extension ladder is a triangular linkage structure, and comprises a group of inner rectangular frame and a group of outer rectangular frame, the two frames are arranged at intervals, the rear ends of two lateral brims of the inner and outer rectangular frames are respectively connected with two link rods; two triangular brackets are respectively fixed on the rear wall of the box body, a connection cross bar, a middle round bar and a front end round bar are all arranged between the two triangular brackets, the upper ends of the two link rods at the top of the extension ladder are respectively fixed together with the middle round bar, a hauling cable storage box of the slow descending retracting mechanism is fixed at the rear wall of the box body, a guide rack is fixed at the front end of the hauling cable storage box, and the lower end of the hauling cable is fixed at the bottom brim. The triangular linkage type emergency escape extension ladder has the advantages of being compact in structure, convenient to operate, strong in evacuation capability and wide in application range, realizing linked opening and closing of upper and lower cover plates and slow extension of the extension ladder, and being capable of finishing rapid evacuation and escape of large numbers of people in buildings under emergency situations, such as fire emergency accident.
Description
Technical field
The utility model relates to personnel escape's deliverance apparatus, particularly a kind of triangular coupling rod formula 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 parts of this novel emergency escape extension ladder are formed and original application patent basically identical, all comprise casing, delay and fall recovering mechanism and three parts of extension ladder, and difference is the structure difference of extension ladder.
The utility model content
The purpose of this utility model is at above-mentioned existing problems, provides a kind of and can make that personal security escape, evacuation speed are fast, safe and reliable, convenient for installation and maintenance, the triangular coupling rod formula emergency escape extension ladder of long service life, good looking appearance.
The technical solution of the utility model:
A kind of triangular coupling rod formula emergency escape extension ladder, comprise casing, slow recovering mechanism and the extension ladder of falling, it is characterized in that: extension ladder is triangular coupling rod formula structure, rectangular frame and one group of outer rectangular frame also arrange at interval in comprising one group, rectangular frame is positioned at outer rectangular frame in during contraction, in, outer rectangular frame includes two band iron type sides, a round bar type back and a bar shaped front, the bar shaped front by rotating shaft respectively with interior, the front end of two sides of outer rectangular frame connects, in, the rear end of two sides of outer rectangular frame connects by two two connecting rods respectively, the two ends of adjacent two front bezel fixedly have two vertical stone dead wires respectively, and the length of stone dead wire equates with the straight length of two connecting rods; On the casing rear wall, fix two triangular supports respectively, triangular supports is plank frame, be provided with between two triangular supports and connect cross bar, middle part round bar and front end round bar, the upper end of two two connecting rods in extension ladder top is fixed with the middle part round bar respectively, slow the pull rope receiver of recovering mechanism falls and the rear wall of casing is fixed, saddle is fixed in pull rope receiver front end, and pull rope is descending by saddle, and pull rope lower end and base are fixed.
The course of work of the present utility model:
1) use: 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, and extension ladder is because the effect vertical stretching of gravity, because the speed limit function of slow descending mechanism, the rate of stretch is limited in the scope of setting, and till extension ladder was down to down the first floor plate, this moment, the escape personnel can hold handrail and the downward one deck evacuation of extension ladder of upper cover plate.
2) removal process: after finishing using, administrative staff hold the recovering mechanism rocking handle, constantly carry out swing, recovering mechanism is regained rope, and the traction extension ladder from a bottom joint by the joint withdrawal, shrink finish after, throw off recovering mechanism by the rotating spanner, make extension ladder and slow descending mechanism return to normal condition, closed cover plate up and down, removal process finishes.
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.
