The specific embodiment:

This fire-fighting escape device constitutes (referring to accompanying drawing 1-3) by fixedly door pocket 1, door-plate 2, pawl type movable supporting 3, gear-box 5 and back-up tong 29, and fixedly door pocket 1 is fixed on by hold-down screw on the cross section of body of wall 22 (as shown in Figure 4).Door-plate 2 is connected with the fixing upper end of door pocket 1 by door opener 20, and the both sides of door-plate 2 are equipped with the pawl type movable supporting 3 supporting with the interior ratcheting pawl latch of fixing door pocket 1 23 respectively, in the bottom of door-plate 1 locking device 28 are housed, and gear-box 5 is equipped with at the middle part.Rolling wheel axle 8, gear shaft 10 and an angular wheel shaft 13 are housed in gear-box 5, be fixed in gear I9 and the gear II11 engagement of being fixed in gear shaft 10 1 ends on the rolling wheel axle 8, the bevel gear I12 on the gear shaft 10 is meshed with the bevel gear II27 that is contained in angular wheel shaft 13 ends.Flyball assembly 14 is equipped with in angular wheel shaft 13 upper ends.By brake linkage seat 24 brake linkage 15 is housed on the flyball assembly 14, the hydraulic fluid tank 16 on the flyball assembly 14 is connected with brake assembly 18 on being contained in gear-box 5 by hydraulic oil pipe 17.Steel wire rope rolling wheel 4 is equipped with at the two ends of rolling wheel axle 8 respectively, and steel wire rope 6 and cord grip 21 are housed on the steel wire rope rolling wheel 4, and the end of steel wire rope 6 is shaped on suspension ring 7.

This fire-fighting escape device is contained on the outer wall body 22 of building, and after door-plate 2 was passed through locking device 28 and fixedly door pocket 1 is locked, the outside was the same with exterior wall flat, and safety door is equipped with in the inside, does not influence the attractive in appearance of the inside and outside shape of building.This device can be installed in the window below of the half storey stair in every floor room, also can be installed on the place that is fit to installation and needs installation.

During use, when the building accident breaking out of fire of this fire-fighting escape device is installed, the personnel of every floor can go to the stair position that this device is installed fast, open the safety door of the inside earlier, open the locking device 28 of door-plate 2 lower ends again, door-plate 2 flicks into level under the effect of door opener 20; Simultaneously, the pawl type movable supporting 3 of door-plate 2 both sides also is drawn out thereupon, and by ratcheting pawl latch 23 lockings.At this moment, steel wire rope 6 and suspension ring 7 that a side is not involved in the steel wire rope rolling wheel 4 get rid of down, and the escape personnel jumps out after then hand can being stretched into and firmly grasping suspension ring 7 in the suspension ring 7 of opposite side, and then the people is with steel wire rope 6 escape that falls earthward.

For the falling speed that prevents steel wire rope 6 too fast, one flyball assembly 14 is housed on the angular wheel shaft 13 in gear-box 5, when steel wire rope 6 speed descend when too fast, rolling wheel axle 8 opens the flyball in the flyball assembly 14 by gear I9, gear II11, bevel gear I12 and bevel gear II27, by brake linkage 15 control hydraulic fluid tanks 16, hydraulic oil is checked disc brake sheet 19 by hydraulic oil pipe 17 control brake assemblies 18, made the rotating speed decline of rolling wheel axle 8 and make that the decrease speed of suspension ring 7 is slack-off.Because the continuous variation of speed, opening and closing up also of flyball constantly changes, and makes the decrease speed of suspension ring 7 remain unchanged during decline, be the big or little people of body weight when falling speed all be consistent.

When suspension ring on one side 7 fall, 7 risings of the suspension ring that another side is got rid of down, and steel wire rope 6 is involved in the steel wire rope rolling wheel 4 equably by cord grip 21, when the suspension ring of another side rise to door-plate 2 places, next escape personnel then can escape, and repeats so repeatedly to get final product.

When escape in order to race against time, or young personnel be can't use suspension ring 7 time, can adopt to be placed on the other back-up tong of this device 29 and to escape.Adopt the using method of back-up tong 29 escapes to be, the safety belt 25 of back-up tong 29 is lain on the waist, again hand of back-up tong 29 usefulness is held, steel wire rope 6 is passed between three pinch rollers 32, with the handle of the hand person of pinching back-up tong 29, the people then is hung on the steel wire rope 6 by safety belt 25 and back-up tong 29, falls with steel wire rope 6, the another hand then can be had a together landing of old or young people in arms, can help the old,weak,sick and disabled's personal security to flee from.If will hurtle down, the handle of back-up tong 29 can be loosened slightly, then when steel wire rope 6 falls, relative slip in addition between back-up tong 29 and the steel wire rope 6, then the speed of Xia Luoing can be faster.Pinch roller 32 is pressed in three pinch rollers 32 all the time at the following steel wire rope 6 of the effect of spring 30.
