[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
Because the people will hurtle down with gravity acceleration g under free state when high building jumps off, so high-rise escape apparatus must be able to provide enough big resistance to make the people slow down and at the uniform velocity descend, the speed of landing can not too soon can not be too slow.The method of braking control speed commonly used has the combined type braking control speed of mechanical type braking control speed, fluid pressure type braking control speed, pneumatic brake control speed and electromagnetic type braking control speed and several method combination and usefulness at present.The utility model designs a mechanical friction type braking deceleration high-rise escape apparatus.
The structure and the operation principle of motorcycle friction growth trend shoe-type clutch:
Recognize extensive use friction growth trend formula brake or friction growth trend formula clutch in automobile, motorcycle by investigating us.A kind of motorcycle friction growth trend shoe-type clutch, three groups of friction hoof pieces are arranged on the holder of clutch active part, with bearing pin they are connected on the holder, and strain with spring, make between the disk of friction hoof piece and clutch secondary part to keep certain clearance, clutch two parts do not engage at this moment.When rotating speed increases, the suffered centrifugal force of hoof piece is during greater than the pulling force of spring, and friction hoof piece just outwards throws away, and contact with the disk of secondary part, produces frictional force, drive secondary part and also rotate, this moment clutch two parts joint.That friction growth trend formula shoe-type clutch has is simple in structure, reliable operation, advantage that price is low, thereby our decision is transplanted to this structure in the high-rise escape apparatus.
Braking deceleration principle of the present utility model:
Because high-rise escape apparatus will possess the braking deceleration effect, so we have done certain transformation to friction growth trend shoe-type clutch, as Fig. 1 spring 10 is pressed on the friction hoof piece 8 in advance, the tension force that friction hoof piece can be subjected to spring opens in advance, be adjacent on the fixed disc on the frame 6 (shown in Fig. 2), produce stiction between the two, can improve the friction catch deceleration effect of escape apparatus like this, initial velocity is too fast when preventing that the people from escaping, and has reduced survivor's fear.
The people can drive three groups of friction hoof piece fast rotational on the brake disc when escaping.Friction hoof piece produces frictional resistance because centrifugal action further throws away and is pressed on the fixed disk.The rotating speed that utilizes the effect of gear train speedup to increase brake disc simultaneously increases frictional force, and escape apparatus can be slowed down better.
Simultaneously, fixed disk forms a torque to the bearing pin of the frictional force meeting relative fixed hoof piece that friction hoof piece produces, and this torque makes the hoof piece press tightlyer to fixed disk on friction hoof piece, increases frictional force, and frictional force continues the increase torque.So, frictional force, torque, thrust mutual superposition are used for reaching the effective decelerating effect of brake disc.
General structure scheme of the present utility model:
Fig. 3 is the general principles sketch of escape apparatus, and Fig. 4 is the profile effect structural representation of escape apparatus.Escape apparatus comprises Ratcheting one-way clutch 2, reel 1, two-stage roller gear speed increasing mechanism 3 and friction growth trend formula brake disc 5.Product structure is small and exquisite, daily being positioned in the family in balcony or the office.In case breaking out of fire is taken out escape apparatus on the cleek that is hung on balcony or windowsill exterior wall and locking rapidly, the people puts on the safety harness that hangs on the escape apparatus, toward jumping downstairs.This moment is because the effect of gravity, reel is rotated, drive two-stage roller gear speed increasing mechanism and friction growth trend formula brake disc quick rotation, because the pre-tensile force of spring and the double action of centrifugal action, three groups of friction plates on the brake disc are pressed on the fixed disc, fixed disk produces frictional resistance moment to brake disc, and people's decrease speed is slowed at the uniform velocity, and the speed of people about with 1m/s is very fast to fall and safety lands.
For many people recycle, on reel, designed Ratcheting one-way clutch, (when the people falls) brake disc main shaft and then rotates when as the ratchet mechanism in Fig. 5 one-way clutch reel being rotated counterclockwise, (during coiling) brake main shaft does not change when clockwise rotating, and makes coiling fast, easily.
