Below in conjunction with accompanying drawing the utility model is described in further detail:

Embodiment 1

To shown in Figure 7, a kind of high-altitude slow-falling device comprises housing 1, sheave 3, axle 2 and is contained in rope 10 in sheave 3 grooves such as Fig. 1; It is characterized in that: a cover is installed mainly by sharp gear 5 and four slow descending mechanisms that balancing point frame 6 forms being meshed with sharp gear in the described housing 1.

Described axle 2 passes described sheave 3 centers, and vertically also can install rotationally with described housing 1 biside plate, and described sharp gear 5 is equipped with key 4 with sheave 3 and is fixedly connected with described axle 2 with described sheave 3 coaxial settings, described sharp gear 5.

Four balancing point framves 6 of described slow descending mechanism are located on the periphery of described sharp gear 5, are installed between described housing 1 one sidewalls and the housing median septum 111, can freely swing, each balancing point frame 6 comprise both sides band axle journal rocker 61, be fixed on two pairs of balancing points 62 in the rocker 61, the gear teeth of the described sharp gear 5 of described slow descending mechanism stretch in the described balancing point frame 6 and with balancing point 62 and are meshed.

Described slow descending mechanism also comprises the ball 64 that makes described balancing point frame axial location, regulates the adjustment screw 63 of balancing point frame end play and gets rid of nut 65.

The middle position is provided with upper guide roller 7, the lower guide roller 8 of rope and compresses roller 9 under the described sheave 3; Upper guide roller 7 be about each one, the interval of the two is as far as possible little, do not rub and be as the criterion to pass through on two two ropes on guide roller limit, described lower guide roller 8 be positioned at described two upper guide rollers 7 under the middle position, respectively there is a described compression roller 9 both sides of this time guide roller 8.

During use, pass for 11 times with other rope or the suspension hook bearing pin from housing 1 upper end, then be fixed on reliable building or the special frame.Under then the lightweight reel that is wound with rope 10 (drawing among the figure) being thrown to the space that will jump off, at this moment the safety belt on rope 10 other ends is enclosed within it and fixes, just can down delay and fall.After the people went down, rope 10 just drove sheave 3 rotations, and sharp gear 5 also rotates synchronously.Because sharp gear 5 is meshed with the balancing point 62 of balancing point frame 6, produce damping, make the human body decrease speed be slowed to stable speed until ground.After landing, from unfastening one's seat-belt with it, the rope other end that has at this moment raise can descend for another person's same method.

Sharp gear 5 meshes the principle following (balancing point frame and sharp gear 5 with the upper left corner among Fig. 2 clockwise turn to example) that produces damping actions with balancing point frame 6: when the people descended, rope 10 drove sheaves 3 and turns clockwise, and makes sharp gear 5 rotate synchronously (Fig. 1,2).Because sharp gear 5 is meshed with the balancing point 62 of balancing point frame 6, the first balancing point frame 6(Fig. 2,5 that pushes and shoves successively of two gear teeth of sharp gear 5) two balancing points 62 of the first half (pressing the sharp gear direction of rotation), make outwards (the leaving sharp gear gear teeth direction) swing of balancing point frame 6 first halves, balancing point frame 6 Lower Halves inwardly swing simultaneously; At this moment, in addition two gear teeth of sharp gear 5 also push and shove successively balancing point frame 6(Fig. 2,5) two balancing points 62 of Lower Half, balancing point frame 6 Lower Halves are outwards swung, meanwhile balancing point frame 6 first halves inwardly swing again.Balancing point frame 6 such iterative motions.Because the gear teeth of sharp gear 5 are are constantly pushed and shoved the balancing point 62 of balancing point frame 6, the balancing point frame is constantly swung back and forth, the reaction force of the balancing point zygodont wheel gear teeth of balancing point frame has just produced damping action, force sharp gear 5 to rotate equably slowly, coupled sheave 3 also can only rotate slowly equably.So no matter the people from rope 10 which end falls, sheave 3 and sharp gear 5 are done still to rotate counterclockwise clockwise, always balancing point frame 6 swings back and forth, and the rotation of zygodont wheel 5 and sheave 3 produces damping action.

Adjustment screw 63, the ball 64 of getting rid of in

nut

65,61 liang of side shaft journals of rocker all are to swing normal in order to ensure balancing point frame 6.

Embodiment 2

Embodiment 2 is basic identical with embodiment 1 situation, and different is that embodiment 2 has two cover slow descending mechanisms, is arranged at respectively the left and right sides (Fig. 8) of described sheave.At this moment, make a concerted effort larger because of the damping of two cover slow descending mechanisms.Being specially adapted to above or the slow of heavier object of two people falls.Certainly also can be made into the descending lifeline of the above slow descending mechanism of three covers.Also can be made into balancing point frame in the slow descending mechanism and be one, two, three, (embodiment 1 is four) more than four; Also can be made into balancing point in each rocker and be (embodiment 1 is two pairs) more than three pairs, burdensome one by one at this.
