Description

Rope ladder for escaping

1, technical field: this Rope ladder for escaping is to be used for high floor generation wildfire, and staircase is blocked by fire, and a kind of rope ladder that emergency escape pressed for, full name are " high floor emergency escape fire-fighting rope ladder ".Not only can be used in high floor fire-fighting life-saving, can also be used for using when helicopter can't land in the urgent disaster relief.Big flood takes place as the somewhere, the victims of the disaster are enclosed on the isolated island or on the roof, helicopter can't land, and for example Jing'an District, 11.15 Shanghai high residential building fire helicopter can't be close, fire ladder does not have so high, the elevator outage, staircase is blocked by fire, and this moment, that people upstairs just can not jump out of the building if this Rope ladder for escaping is arranged, and can be along orderly the going downstairs of Rope ladder for escaping, automatic rope ladder then can be climbed on ladder motionless, and fastens seat belts, and survivor's safety is landed, old children all can use, and can reduce a large amount of personnel's injures and deaths.

2, technical background: though the horizontal elevator of prior art can be worked continuously, be unfavorable for high floor, go straight up to elevator and can be installed in high floor, but can not descend continuously.Traditional ladder all is to stretch out from bottom to top to use and be subjected to height restriction, can not receive Gansu Province and be kept at roof, and all will have when using the machine power can.Jing'an District, the 11.15 Shanghai high residential building fire in this year and this year China the existence of the fact of a lot of big floods, exposed and still lacked the rope ladder that is installed in roof or balcony and disaster relief helicopter at present, in view of the fire disaster escaping disaster relief of high floor and pressing for of flood disaster prevention and reduction, the applicant works out two kinds of Rope ladder for escaping that fire-fighting life-saving and flood disaster prevention and reduction pressed for.Can be installed on the high roof or on the helicopter of the disaster relief, can make aircraft rescue the people putting down rope ladder from fire high-altitude far away, perhaps balcony or the roof at high building hanging upside down, the survivor can be directly climbs along getting off escape or climb the escape that descends on the compound vertical automatically rope ladder that descends that Automatic Cycle is worked continuously along rope ladder, and first kind of second kind of ratio is simple, flexibly and can receive Gansu Province, first kind of safety of second kind of ratio, quick, can descend continuously, two kinds all can be without electric power, and can be manually and braking.

3, summary of the invention: (1), the hanging Rope ladder for escaping of a kind of list: with one group of 2 flexible steel cable or high-quality wire rope, symmetrical galvanized iron pipe about 40 centimetres or steel pipe that about 2 centimetres of diameters are about is 8 fonts with iron wire and is tightly being bundled on the wire rope of D font firmly, and weld iron wire with electric welding or gas welding, every a 40-50 centimetre of step ladder, length is seen required how long how long just doing from the roof to ground, also sectional splicing, also can be with one group of 2 thinner mild steel link chain, about 2 centimetres iron pipe two pounded penetrate in the chain ring after flat, weld with gas welding or electric welding and chain again.Two kinds of rope ladders all can equally be installed in the roof edge and with electronic and can load onto by hoist engine manually, this different rope ladder all will respectively be put a deep bid at the axle two of hoist engine, to wrap up in the next volume in rope ladder receipts Gansu Province and is advisable.Gravity when manual hoist also will reduce rope ladder and puts down with shallow bid geared sleeve deep bid gear, the gravity that speed of transferring with the control rope ladder and strand are returned also can be established brake or hand braking speed limit in case of necessity.If floor is too high, avoid rope ladder too heavy, also can establish the segmentation using escalator of transfer hoist engine station, yet sectional splicing of Rope ladder for escaping is not so be subjected to height restriction.

Be installed on the helicopter, then under the abdomen of aircraft, to open the wicket that a people can be up and down, during use wicket is opened, put down rope ladder, length is controlled lifting by hoist engine, also available pulley is transferred, and can also put down disaster relief personnel from aircraft when helicopter can not land and land (the dynamic hand gear that do not need on the aircraft); In high roof upper edge Rope ladder for escaping is installed and also will be used telescopic support, rope ladder is paid outer about 20 centimetres of body of wall, hinder hand on body of wall in order to avoid survivor's hand catches rope ladder to rub.Also to rotate on the bracket head with pulley; also should establish 2 groups of angles that reduce the rope ladder turning with top sheave in case of necessity; again toward going down; every about three layers, also need establish support; with short rope or short thin wire or dedicated fastener rope ladder is fixed on the support during use,, above hoist engine, also will covers a cabin on rope ladder in order to avoid the survivor swings too far and strengthens dangerously; protection rope ladder and hoist engine, the exterior wall of cabin then is the roof enclosure wall.A wicket should be arranged, pin at ordinary times, can not open during less than use, after opening, rope ladder top one one side of something also will be established a trapezoidal railing, the survivor climb along the time handgrip, also do not block rope ladder simultaneously fully, this cabin should be named as the interior wall of " emergency exits " outlet also should establish Yishanmen, allows manager's entrance management and survivor enter on the rope ladder.Four limits of every high building, 1-2 emergency exits all should be established in every limit, each outlet all should be provided with hoist engine or hoist engine lower margin Luo silk and support, as long as rope ladder then every building has 2 covers on the spot, be contained on the trolley with rope ladder or together with hoist engine etc. at ordinary times, just in case during breaking out of fire, see which side is beneficial to escape and is installed in which side with regard to pushing away rapidly, every side 2 cover rope ladders are because need one to be enclosed within outside the staircase window, are beneficial to survivor's Rope ladder for escaping from the window opening of each floor, and an other cover is inflammable too big, window is blocked by fire, be located at the place of no window, just can escape, there is fixing Rope ladder for escaping on certain every limit for well.This being suitable for built high building.

(2), a kind of continuously automatically decline rope ladder: this rope ladder is the same with the former basic principle, but different is, can descend automatically, and the survivor can lie prone motionless on ladder, and also available safety belt is pinioned, and makes the people safer, old children all can, treat that rope ladder drops to ground automatically.And rope ladder is compound, not that the former is unidirectional, one side is automatically to descending, one side then can rise automatically, institute's uplink load can not equal or exceed descending load, also having different is to be difficult for maybe can not receiving Gansu Province, do not need the rope binding fixing yet, this rope ladder itself is fixing, it seems that compound rope ladder side be the equally circulation of image-tape saw, respectively there are a pair of trough of belt and toothed dish in two up and down, be provided with axle in the middle of the dish and be provided with braking equipment, last under can brake, middle axle will have 10 centimetres at least from step, just do not catch the palmistry friction of step to hinder hand with the survivor, it is many that the trough of belt and the toothed dish outside side of a ship will exceed groove, at least to exceed more than 5 centimetres, inner face one side will be with tooth, lacking of between cog wants semicircle, promptly be the bulldozer gear-like, and to match with the distance of step, groove will have step institute soldering iron silk groove knot or chain level and oblique tone hole to slide and can not brake and excessive wearing and tearing in order to avoid load is heavy, the tooth of inside then is the safety when protecting operation that tangles step, the gear shaft of roof is then wanted to bear more than whole ladder and band people's the weight, every layer or every about three floors, establish the fluted disc pulley of a pair of foregoing trough of belt approximately, preferably can integral stop, (this need brake with electronic equipment overall operation, with remote controller is best, must also artificial braking to be arranged at roof and ground, in case electronic equipment is malfunctioning) no matter be that wire rope rope ladder or the steel wire on the both sides of chain rope ladder or chain all will cover with plastic housing or iron sheet outer casing, in order to avoid the survivor is pressed into finger in the gear grooved, the outside of gear grooved also will have outer pulley to block, the swing of control rope ladder, the load that rises surpasses or then uses electric winch when equaling down load down, and this automatic rope ladder only is suitable for newly-built high building.High building will stay special-purpose vertical shaft, and this automatically continuously decline rope ladder speed is fast and safety is faster than elevator, and escape all can be rapidly down to the level land, and the fireman can utilize the jacking row disaster relief of going upstairs of the descending weight band of survivor simultaneously.
