Second rope 71 slave linkage section to the junction of deceleration device 50 part be interlude 712, interlude 712 extend and center of gravity Jing Guo rack 10 in gravity direction.Specifically, in the present embodiment, interlude 712 is mainly the second rope 71 part within warehouse portion 11.

Such second rope 71 can ensure that the decline of rack 10 is still smoothly, not have a wide range of when playing a role Inclination jolt.

Further, in the present embodiment, rack 10 has four symmetrical stringers 15, reel 312 and the first rope 33 Quantity be four, four reels 312 are symmetrically distributed in rack 10 and can be by 314 drive coordination of second gear group Rotation, each first rope 33 are arranged respectively along the length direction of a stringer 15, and the quantity of linkage section is four, each connection Duan Yuyi first 33 cooperation of rope.

Four first ropes 33 are just mating with four stringers 15, and four first ropes 33 being evenly distributed can ensure well Stability during the decline of rack 10.

The principle of the present embodiment is:

The roof beam structure 200 of escaping mechanism 1000 is solid with one end of the first rope 33 as the outer not facility from deceleration mechanism 100 It is fixed.When for example escaping mechanism 1000 is applied on high building, roof beam structure 200 is installed on high building, and configuration can be considered and stretch Contracting equipment is come so that roof beam structure 200 also has locomotivity, in order to make rack 10 close or separate relative to tall building wall. Telescoping mechanism is not only to propose optional scheme herein at the improvement of the application, do not repeat them here.

In the bottom in warehouse portion 11, pedal assembly 90 is installed, for personnel standing, pedal assembly 90 include pedal and Pedal drive part, when personnel are trampled on pedal, the gravity of personnel can pass to pedal drive part, pedal drive by pedal Part can be by weight transfer to deceleration device 50, and to play the role of assisted deceleration, such decrease speed will not be too fast, avoids people Member is injured.Certainly, pedal assembly 90 is also more mature general technology, here for the main contents for being easy to understand this programme And only do simple introduction.

Personnel are in warehouse portion 11, decline with the decline of rack 10, for the efficiency of escape, the speed of decline is general It is preferred with 1.5m/s-1.7m/s, such speed is easy the vertebra to people when reaching ground if directly instantaneously only stopping It damages, when having old man, little Hai Shi in escape personnel, such injury can be more serious.But if under merely reducing Speed when drop, and the efficiency of personnel escape can be made to be affected.

Therefore, in order to eliminate such drawback, by taking the present embodiment as an example, the rack 10 of the application is reached apart from ground 5m (detailed, when referring to the reduction part 13 of 10 bottommost of rack apart from ground 5m), trigger unit 332 can be contacted with stressed member 73, With the continuous release of the first rope 33, trigger unit 332 moves up with stressed member 73 and pulls the second rope 71.

As the second rope 71 is pullled, turntable 7521 also drives shaft 7523 to rotate while the rope of release second 71, turns 7523 one side of axis is that torsion is passed to deceleration device 50 by first gear group 77, on the one hand but also clockwork spring 754 It is twisted, so that shaft 7523 has counter-rotational trend.

In this way, stopping after deceleration device 50 receives the active force that the second rope 71 is passed over by first gear group 77 The amplitude that vehicle handle is struck is gradually increased, and is stopped so that drum brake gradually stops second gear group 314.After the brake of second gear group 314 is stopped, The reel 312 being sequentially connected with second gear group 314 is also stopped by brake, to can not rotate.This allows for the release of the first rope 33 Also can thoroughly stop.Finally rack 10 is stopped.

Must it is noted that from 10 bottom of rack from the ground 5m to final rack 10 when reaching ground, brake lever quilt The amplitude stirred, which needs to ensure, only to stop second gear group 314, and brake is not stopped completely yet when avoiding rack 10 to ground.

By used in escaping mechanism 1000 the application from deceleration mechanism 100, brake of the personnel when reaching ground Process is the process gradually carried out, stops without instantaneous time brake, so as to avoid injury to personnel, particular avoids personnel Vertebra it is impaired.In addition personnel are not needed, the only process of stopping is controlled and can only be stopped when reaching ground, even if being met in high building When needing to escape to emergency, only old man or child personnel thin and weak in this way take escaping mechanism 1000, and can It not will receive the damage of emergency stop when support personnel's escape is to ground, it is highly beneficial for personnel safety.

In view of that may carry out multiple personnel escape, motor 101 can be set in the reduction part 13 of rack 10 And the battery pack 102 powered for motor 101, battery pack 102 is it is contemplated that keep daily electricity with the power supply of high building Deposit according to circumstances (such as the area without shade for being mounted on high building) can also select the mode of solar recharging that electricity is kept to store up It is standby.The output shaft and second gear group 314 of motor 101 are driven cooperation.

In this way, can reach ground when needing to carry out personnel's decline escape next time in first time personnel and go out Behind storehouse, the switch for pressing motor 101 is allowed to work, rotates backward second gear group 314, so that reel 312 is anti- To rotation by 33 winding of the first rope, and then rack 10 is driven to rise.First rope 33 is due to gradually being wound, so that trigger unit 332 separate with stressed member 73.After second rope 71 loses the active force of stressed member 73, clockwork spring 754 drives turntable 7521 reversed By the second rope 71, gradually winding resets for rotation, and rotating backward by shaft 7523, so that first gear group 77 reversely turns It is dynamic, so that brake lever voluntarily gradually resets, weaken the braking action of drum brake gradually, enables reel 312 First rope 33 is further wound and drives rack 10 to rise during winding, until reaching initial position, facilitates people Second of escape of member.Certainly, it can repeat the above process if personnel are more and more frequently be escaped.

In conclusion the application's can pass after being applied to escaping mechanism 1000 by slowing down from deceleration mechanism 100 Dynamic component, deceleration device 50, cooperate pay-off unit, rack 10 can be carried out automatic retarding, and gradually stop in predeterminated position brake, It is injured due to 10 emergency stop of rack in predeterminated positions such as escapes to ground so as to avoid personnel, protection staff escape safety.

The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
