The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, escape apparatus of the present utility model, its structure comprises the main shaft 12 that is arranged in the hold-down support 22, being disposed with friction cushioning mechanism 1, load carrier 3, going back to rope mechanism 2, centrifugal mechanism 5, friction catch mechanism 4 on the main shaft 12.Load carrier 3 comprises the reel of a coiling rope 24, and rope 24 is the decline rope of life-saving, is set with back the freewheel clutch 17 of rope mechanism 2 in the reel, cooperates by key between freewheel clutch 17 and the main shaft 12 and fixes.
As Fig. 2, the structure of friction cushioning mechanism 1 is, be included in and be set with slider waveguide rod 8 on the main shaft 12, main shaft 12 and slider waveguide rod 8 cooperate by key, a plurality of radius poles outer end of slider waveguide rod 8 respectively is connected with a friction slip 7, friction slip 7 keeps the face sliding-contact with the circumferential inner surface of brake pad shell 6, and the spring on each radius pole guarantees the pretightning force to friction slip 7.The elastic force of spring is added on centrifugal 7 produces the moments of resistance, play the pretension effect with shell 6 frictions.Speed can not be undergone mutation when beginning, promptly play cushioning effect, reach the gradual change of speed at the beginning boost phase.
As Fig. 3, the structure of centrifugal mechanism 5 is, comprises the fulcrum 13 that is fixed on the main shaft 12, and fulcrum 13 is hinged with lever 14, and an end of lever 14 is equipped with centrifugal hand hammer 21, and the other end of lever 14 is connected with fixed cover 23 in the friction catch mechanism 4 by power transmission pull bar 9.
As Fig. 4, the structure of friction catch mechanism 4 is, on hold-down support 22, be fixed with the support 20 of tubular, on main shaft 12, be provided with fixed cover 23 by key, support 20 inner surfaces are provided with a plurality of static friction discs 19, fixed cover 23 is provided with a plurality of dynamic friction discs 10, and static friction disc 19 arranges at interval successively that with dynamic friction disc 10 certain pressure can produce rubbing action when contacting down.Be equipped with in the termination of power transmission pull bar 9 and compress end cap 11, when centrifugal hand hammer 21 produces a centrifugal force under the effect of main shaft 12 rotations, power is converted into the pulling force of horizontal direction by connecting rod 14 and fulcrum 13, pulling compresses end cap 11 roof pressure movable friction plates 10, movable friction plate 10 and static friction sheet 19 are compressed produce a resistance, feed back on the main shaft 12, thus the rotating speed of reduction main shaft 12, and then make hedging people's decrease speed reach relatively stable.
As Fig. 5, go back to rope mechanism 2 and comprise sprocket wheel 16, sprocket wheel 16 is connected with freewheel clutch 17 by chain 15, freewheel clutch 17 and main shaft 12 are connected by key, sprocket wheel 16 is provided with hand crank 18, sprocket wheel 16 is connected with motor coaxle simultaneously, and motor is connected with batteries, limit switch and gauge tap, and limit switch is arranged on reel and goes back to rope mouthful place.When returning rope, reel and motion of main shaft are separate, and rope is received in the rotation of driven by motor reel, and when the rope end hook was run into limit switch, limit switch can be controlled the motor stall, finished back the rope action.After first people used rope to hang down to untie rope, top people can make the fast automatic withdrawal of driven by motor rope by opening gauge tap.When accumulator electric-quantity is not enough, can't use motor to return rope, top people can be by hand crank 18 withdrawal of manually will restricting.
As shown in Figure 5, the outer shroud that freewheel clutch 17 comprises the star-wheel that is connected with the escape apparatus main shaft, is connected with reel, be provided with in the wedge shape cavity between star-wheel and the outer shroud and be pushed the tight roller of masthead, the roller number is 3-8, and each roller is all pushed ahead with thrust by spring and push rod and is in half wedging state.Star-wheel is driving link and does when rotating counterclockwise that freewheel clutch is in engagement state, and this moment, reel and main shaft rotated synchronously, and whole device normally moves; Outer shroud is main motion and does when clockwise rotating that freewheel clutch is in released state when receiving rope, and the motion of reel and the motion of main shaft are independent separately, thereby makes the process of receiving rope carry out smoothly.
The escape apparatus of band automatic stable device of the present utility model, load carrier 3 wherein links to each other with centrifugal mechanism 5, the rope of load carrier passes motion to centrifugal mechanism 5 when descending, thereby make centrifugal mechanism 5 runnings drive friction catch mechanism 4 and produce braking effect, reduce the rotary speed of main shaft again by negative feedback mechanism (comprising friction cushioning mechanism 1, friction catch mechanism 4, centrifugal mechanism 5), thereby reach the purpose that speed stabilizing descends.When reusing back rope, freewheel clutch 17 is thrown off, and motor drives the reel backward rotation for input power, realizes electronic quick time rope, and the existence of limit switch makes whole time rope process accurately put in place.Do not have electricity in particular cases at battery, can enable standby hand crank 18, realize manually returning rope.
The high building of the utility model band automatic stable device is slow to fall escape apparatus when using, and at first the pretightning force of friction cushioning mechanism 1 is added on the main shaft 12, when the people takes when hanging indigo plant, under the acting in conjunction of gravity and pretightning force, hangs blue beginning and slowly quickens.When speed reaches relatively constant speed V when (promptly this moment, the moment of resistance equated with active moment), centrifugal mechanism produces centrifugal force with the rotation of main shaft, drag static friction disc 19 and contact the generation friction with dynamic friction disc 10, thereby produce the braking moment that acts on main shaft, the rotating speed of main shaft is reduced, realize that escape personnel's decline slows down.Instantly the reduction of speed degree is lower than V, thereby reducing, the rotating speed of centrifugal mechanism make static friction disc 19 and dynamic friction disc 10 friction forces reduce the moment of resistance that produces before, thereby main axis rotation is quickened, people's decrease speed is accelerated, guarantee the goal pace that departs from that speed that the people descends can be not too much, finally realized the effect of automatic stable.And, between reel and main shaft, adopt freewheel clutch to be connected, when descending, the people is rotated in the forward, and main shaft and reel rotate synchronously, main shaft and reel clutch during the receipts rope, both move relatively independent.When first people goes down after success is rescued, top people can pass through back the electronic control of rope mechanism, smoothly rope is regained, and perhaps under the situation of battery loss electric weight deficiency, can also go back to rope mechanism by manual operation and receive rope.
The utility model escape apparatus the driving phenomenon can not occur, and centrifugal braking mechanism comprises two parts, under the situation that an end lost efficacy, and other end effect, double action can satisfy actual security needs.
