Problems solved by technology

[0004] The brake pads of the above two structures do not have a certain guiding mechanism during the reset process. During the slow down process, the connecting block frequently moves centripetally or centrifugally, which is prone to jamming, resulting in brake failure, stopping or failure. brake risk

Embodiment 1

[0035] Such as Figure 1 to Figure 5 As shown, the present invention includes frame, safety rope mechanism, planetary acceleration mechanism, centrifugal mechanism and friction deceleration mechanism;

[0036] The frame includes a frame plate 1, a screw 4 and a casing 5, and there are two frame plates. The rope guide mechanism and the rope winding drum are located between the two frame plates, and the two frame plates are fixedly connected by the screw and the sleeve. ;

[0037] The safety rope mechanism includes two rope guide rods 2 and a rope winding cylinder 3, the rope winding cylinder 3 is wound with a safety rope (not shown in the figure), and the free end of the safety rope passes between the two rope guide rods 2;

[0038]The planetary acceleration mechanism is arranged in the rope winding cylinder 3, and the planetary acceleration mechanism includes an inner ring gear 6, a planetary gear 7 and a central gear 8 from the outside to the inside. The planetary gear shaf...

Embodiment 2

[0043] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as Figure 6 As shown, a plurality of heat dissipation holes 19 are arranged on the friction hub 17, and the heat dissipation holes 19 are arranged obliquely. The extending direction of the heat dissipation holes 19 from the outer end to the inner end is opposite to the rotation direction (arrow direction) of the rope winding drum.

Embodiment 3

[0045] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as Figure 7 As shown, the outer wall of each rope guide rod 2 is sleeved with a guide pulley 20 , the edges of the two guide pulleys 20 are in contact, and the rope is located between the two guide pulleys 20 .

Abstract

The invention belongs to the technical field of high-rise escape safety tools and particularly discloses a working condition self-adaption high-rise emergency escape device. The working condition self-adaption high-rise emergency escape device comprises a rack, a safety rope mechanism, a planetary acceleration mechanism, a centrifugal mechanism and a friction speed reduction mechanism. The centrifugal mechanism comprises a centrifugal pan, a first centrifugal block, a second centrifugal block and extension springs. The centrifugal pan and a center gear shaft are coaxially fixed. The first centrifugal block and the second centrifugal block are symmetrically and slidably arranged on the centrifugal pan. The first centrifugal block and the second centrifugal block are each provided with two hanging points. The two ends of each extension spring are connected with the corresponding hanging points of the first centrifugal block and the second centrifugal block. Through the planetary mechanism acceleration and centrifugal block friction speed reduction principles, it is guaranteed that escape device drops at constant speed within the range of 0.5-1.5 m / s in the whole process. The escape device is ingenious in design, convenient to operate, safe, reliable and particularly suitable for high-rise emergency escape of people without any escape knowledge and skills and has good applicationand popularization value.

Description

technical field [0001] The invention belongs to the technical field of high-rise escape safety tools, in particular to a working condition self-adaptive high-rise emergency escape device. Background technique [0002] With the rapid development of urban buildings in my country, there are more and more high-rise and super high-rise buildings, and the fires in high-rise buildings are also on the rise. The fire emergency rescue capabilities of high-rise buildings in my country are seriously insufficient, and it is difficult to meet the needs of real fire fighting. In the event of a fire, emergency evacuation is the key issue. Equipping various forms of escape and rescue equipment in the building to ensure that the trapped people can effectively save themselves and each other, and quickly evacuate to a safe area is the primary goal that must be achieved. At present, the simple rope escape devices commonly used in the market have higher requirements on the operation and physical s...
