Abstract
The invention discloses a high-rise building fire escaping chain belt ladder. Currently, high-rise buildings are not provided with specific fire escaping facilities, fire lifts can only be used by firefighters, a large number of personnel go downstairs by slowly walking along emergency staircases, and a lot of personnel may be wounded or die once a fire happens, particularly, a large number of personnel will die once accidents like the U.S. 9/11 terrorist attack accident happen. The high-rise building fire escaping chain belt ladder can ensure that a large number of trapped personnel can quickly escape, and casualties can be reduced to the maximum degree within the shortest period of time. According to the high-rise building fire escaping chain belt ladder, a fire escaping lift well is arranged in a high-rise building, and a chain belt ladder body is arranged between escaping ladders; a ladder frame is made of profiles and is provided with two parallel rolling ways with a plurality of rollers, the upper end and the lower end of the ladder frame are respectively provided with a pair of chain wheels, and two closed chain belts composed of a plurality of chain belt sections are hung between the upper chain wheels and the lower chain wheels respectively. People escaping from fires can squat on seat boards on the chain belt sections and slide downwards under the action of gravity, and will be transferred in an elastic mode when arriving at a lower chain wheel and be transferred to a next-floor ladder, repeatedly, people arrive at the exit at the bottom floor. The high-rise building fire escaping chain belt ladder is fast in escaping, safe, reliable and free of power.
Description
Technical field
The present invention relates to a kind of fire of high-rise building escape chain band ladder.In skyscraper owing to there is no ad hoc passway for escaping facility.Fire lift is enough fire fighter's uses only, and a large amount of personnel can only lean on the escape stair walking downstairs, and speed is extremely slow.In case so the skyscraper breaking out of fire often can cause a lot of casualties.Especially, as U.S.'s the terrorist attacks on September 11,2001, again occur, can cause again a large amount of people's injures and deaths.The present invention can be in very short time, makes a large amount of trapped personnels scene that takes a powder, thereby can reduce to greatest extent casualties.
Background technology
Known, skyscraper does not have ad hoc fire drill facility at present.When fire occurred, elevator can not use, and a large amount of personnel can only lean on the escape stair walking downstairs, so speed is very slow, often causes a lot of casualties.Especially, as the U.S. " 911 " attack of terrorism, can cause more casualties.
Summary of the invention
In order to fill up present skyscraper, there is no ad hoc fire disaster escaping facility and lane device, when fire occurred, elevator can not use, and the people can only lean on the escape stair walking downstairs, so speed is very slow, often causes a lot of casualties.As the U.S. " 911 " attack of terrorism, can cause the deficiency of more casualties, the present invention releases a kind of fire of high-rise building escape chain band ladder.It can make a large amount of trapped personnels scene that takes a powder in very short time, reduce to greatest extent casualties.
The technical solution adopted for the present invention to solve the technical problems is: in skyscraper, establish the escaping ladder for fire hoistway, in hoistway, establish between Emergency Ladder for every layer, between all two layers of up and down Emergency Ladders, set up fire of high-rise building escape chain band ladder.
Fire of high-rise building escape chain band ladder is made ladder by section bar, and on it, poker lays two parallel raceways, on raceway, has a plurality of by roller bearing roller fixed thereon.Pair of sprocket is respectively established at two ends, ladder up and down, between sprocket wheel, hangs an endless chain band, and the smooth position of chain band rides on the roller of raceway, in lower sprocket the place ahead, on ladder, establishes the seat plate carrying device nearby.When this chain band joint was slipped to this place and passes through, carrying device can be sent the survivor who squats on seat plate on it, forwards the bottom ladder to.
The chain band is to be connected to form by polylith chain band joint, two parallel synchronization chain joints are made by the chain band joint both sides section of stooping, its width, pitch and sprocket wheel coincide, and on every chain band joint, rotatable pit shape seat plate are arranged, (according to width and needs, can be designed to duplicate rows or multirow).
Carrying device top roller is installed in bearing and bearing block combination by axle, the latter is placed on the spring of spring base, and its underpart pole is inserted in spring, and both sides are established guide post and are through in the spacing plate hole with the spring base one, to position, spring base is fixed on ladder with positioning roller.When have the survivor squat on seat plate by the time, because of the seat plate bottom lower than the roller height, so roller can be done upper top to its send action.Owing on device, spring and spacing being arranged, so it is soft sending.
Its end of seat plate has two to be in rotating shaft local bag pressure is arranged, and these rotating shaft two ends are placed in the bearing that is fixed on chain band joint relevant position, the back side.Two keep-springs are placed on two bearing inside edge axles, and its end withstands on chain band joint backplate, and the other end suppresses in present positional plate hole, makes under the seat plate bullet to become the pit shape.There is the rigid limit plate its underpart, and its end is fixed on the chain band joint back side, and another circular-arc free end is spacing at seat backboard face.The survivor squats on the seat plate of chain band joint, by Gravitational sliding, during to lower sprocket, has carrying device that the survivor is sent rapidly, sends the back seat plate and restores to the original state rapidly.
The invention has the beneficial effects as follows, when skyscraper suffers fire or the attack of terrorism, make a large amount of trapped personnels rapidly and fleeing the scene of safety, farthest reduce casualties, it is safe, reliable, unpowered.
The present invention is further described below in conjunction with drawings and Examples.
