The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art through specific situations.

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Examples

The embodiment provides a high-rise self-rescue escape device, as shown in fig. 1, 2 and 4, comprising:

a reel 1;

the rope winding disc 3 is connected with the reel 1, can synchronously rotate along with the reel 1 and is used for winding a safety rope;

the rotating disc 2 is connected with the reel 1 and can rotate around the reel 1, a plurality of ball mounting grooves 21 are formed in the edge of the rotating disc 2, and a ball 22 is arranged in each ball mounting groove 21;

the speed change mechanism is connected with the rope winding disc 3 and the rotating disc 2;

the shell 5 is coated outside the scroll 1, the rotating disc 2 and the rope winding disc 3;

and a ball chuck 4 fixed to the housing 5 at the inner side of the housing, wherein a groove 41 capable of being engaged with the ball 22 is formed at the inner edge of the ball chuck 4, and the ball 22 is engaged with the groove 41 when being rolled out from the ball mounting groove 21.

The working principle of the high-rise self-rescue escape device of the embodiment is shown in figures 6 and 7. When the safety rope is pulled out at a low speed (i.e., when the user descends), the rotation speed of the rope winding disc 3 is slow, which is equivalent to the slow rotation speed of the rotating disc 2, and the balls 22 in the ball mounting grooves 21 of the rotating disc 2 are only engaged with the grooves 41 in the lower half of the ball 22 as shown in fig. 6, and the balls 22 are engaged with the grooves 41 to generate resistance to the rotating disc 2 in rotation, so that when only a small part of the balls 22 are engaged with the grooves 41, the braking force to the rotating disc 2 is small; if the withdrawal speed of the safety rope is high (i.e., the lowering speed of the user is high), the rotation speed of the rope winding disc 3 is high, which is equivalent to the high rotation speed of the rotating disc 2 (the centrifugal action on the balls 22 is high), and the balls 22 in the ball mounting grooves 21 of the rotating disc 2 are engaged with the grooves 41 by moving away from the axial center as shown in fig. 7, so that the braking force to the rotating disc 2 is greatly increased when most of the balls 22 can be engaged with the grooves 41. When the braking force is sufficiently large, the safety line withdrawal speed can be reduced (i.e., the user descent speed is reduced) until a balanced condition is reached, so that the braking force provided by the balls 22 just ensures that the safety line withdrawal speed is unchanged.

The high-rise self-rescue escape device disclosed by the embodiment can be used in high-rise refuge scenes, for example, in rock climbing movement, and the user can effectively avoid accidental falling accidents after wearing the high-rise self-rescue escape device disclosed by the embodiment in the rock climbing movement, so that the safety of the rock climbing movement is greatly enhanced, and the safety guarantee is provided for the rock climbing movement.

The service life of the steel ball is longer than that of the friction plate, the heat generated during braking is much lower than that of the friction plate, and the braking effect is not obviously reduced when the safety rope is attached with oil stains and water.

Preferably, in the high-rise self-rescue escape device of the embodiment, the speed change mechanism is a planetary gear speed change mechanism. The planetary gear speed change mechanism is more stable than a simple gear mechanism in self transmission on one hand, and on the other hand, the transmission ratio of the rotating disc 2 and the rope winding disc 3 is greatly increased, so that the low rotating speed of the rope winding disc 3 causes the high rotating speed of the rotating disc 2, and the centrifugation of the balls 22 is facilitated.

Preferably, as shown in fig. 3 and 4, the high-rise self-rescue escape device of the embodiment comprises:

a carrier 6 fixed to the case 5;

a sun gear 23 fixed to the center of the rotary disk 2;

the planetary gears 32 are arranged along the circumference of the rope winding disc 3, and the rotating shaft of the planetary gear 32 is fixed on the rope winding disc 3;

the sun gear 23, the planet gear 32 and the planet carrier 6 are mutually matched.

Preferably, the high-rise self-rescue escape device of the embodiment, as shown in fig. 5, one side of the housing 5 is provided with an opening 51 for the safety rope 8 to extend through.

Preferably, as shown in fig. 5, the opening 51 of the high-rise self-rescue escape device of the present embodiment is provided with a guide wheel 7 for guiding the safety rope. The guide wheel 7 can ensure that the pulling direction of the safety rope 8 is more accurate, and the slipping and knotting are not caused.

Preferably, in the high-rise self-rescue escape device of the present embodiment, as shown in fig. 5, the guide wheels 7 are three in total, two of the guide wheels 7 are arranged side by side, and the other guide wheel 7 is arranged between the two guide wheels 7; the guide wheels 7 each have an arcuate groove 71 in their circumference. The groove 71 prevents the safety line 8 from slipping off when it is being pulled.

Preferably, as shown in fig. 8, two high-rise self-rescue escape devices are provided, wherein the rope winding disc 3, the rotating disc 2, the speed change mechanism and the ball chuck 4 are symmetrically provided.

Preferably, in the high-rise self-rescue escape device of the embodiment, as shown in fig. 6 and 7, the depth of the groove 41 is smaller than the radius of the ball 22. Too deep a groove 41 may cause the ball 22 to jam.

Preferably, in the high-rise self-rescue escape device of the embodiment, the disc surface of the rope winding disc 3 is provided with a plurality of hollows. The hollow out is beneficial to reducing the whole weight of the equipment and is convenient to wear.

Preferably, in the high-rise self-rescue escape device of the present embodiment, as shown in fig. 8, the planet carrier 6 and the ball chuck 4 are fixed in the housing 5 by a plurality of screws or bolts 9, and the alignment portion of the planet carrier 6 and the ball chuck 4 shares one screw or bolt 9.

In light of the foregoing description of the preferred embodiments according to the present application, it is to be understood that various changes and modifications may be made without departing from the spirit and scope of the invention. The technical scope of the present application is not limited to the contents of the specification, and must be determined according to the scope of the claims.
