Time specifically used

In the spring loaded support bar of the present embodiment, spring tension is 369.2N, deceleration device is mainly tied by circle, spring loaded support bar becomes with thick compression spring set, two hairspring formula support bars are all 60 ° of angles with safety rope, and one end that hairspring contacts with safety rope is equipped with rubber blanket (increasing coefficient of friction effect), in the same horizontal line, 2 springs become symmetrical distribution to the rubber blanket end of two hairsprings.

Its operation principle is as follows:

Design requirement is landing 6m front reduction gear, and then in the end the rope of 6m is provided with circular knot every half meter, and the diameter of circular knot is slightly larger than the distance of two hairspring rubber blanket ends, and circular knot diameter is 0.8cm, and the distance of two hairspring rubber blanket ends is 0.5 centimetre. when survivor escapes with this device, during from ground 6m, the rubber blanket end in contact of circular knot and two hairsprings, produce friction (loss rope part potential energy), and spring loaded support bar contraction simultaneously makes kinetic energy transfer elastic potential energy to, reach the purpose allowing safety rope slow down, so that it is be unlikely to excessive velocities to cause damage that survivor arrives ground, relation due to the shape of node and two hairspring angles, node can relatively easily through the gap between two hairsprings, not only can the length of fully utilized safety rope, but also serve the effect of deceleration, angular relationship due to two hairsprings, 2, rubber blanket end creates bigger extruding force, further increase friction, safety rope is made to reduce speed now, arriving ground hourly velocity is about 1m/s, after first survivor arrives safe and sound ground, and unclamp handle, owing to safety rope is no longer influenced by the gravity of human body, it is limited only by the control of circulation escape device, so safety rope starts return, when handle arrive initial time position time, owing to buffer unit (namely slightly compresses spring, clamp and handle) effect, the speed that can make handle tends to 0m/s in very short time, at this moment the follow-up action escape treating survivor just repeatable above survivor.

Scroll spring is unlike common spring only in transverse compression and elongation, and it has in radially stretchable characteristic, and one end of scroll spring is connected with bobbin, and fastens, and other end is connected with cotton rope. When there being survivor's practicality, owing to its gravity is more than the elastic force of scroll spring, therefore can decline smoothly and escape; When survivor arrives safe and sound ground, when unclamping safety rope, owing to stress disappears, scroll spring restitution, safety rope can be made to rebound rapidly, safe escape for next bit survivor is ready, when whole device does not stress (namely first escape personnel is behind ground), compression spring is stretched out, and the gear that rope rotates the gear on axle and decelerator does not engage, cause that decelerator lost efficacy, thus can make the speed that rope is rebounded by scroll spring faster.

Rope reclaims link: the gear that rope rotates the gear on axle and decelerator does not engage, speed control thus can be made to depart from with left-half, this would not affect speed and the efficiency that rope reclaims, but drive motor and decelerator are in work, and when rope reclaims complete, cylinder and speed control also just quit work.

Rope reclaims principle: it is stainless steel disc strip that whole life line is initially the principle design being with ribbon, the width of this strip is 4cm, the material of last 6m is rope, when in the end several meters of rope owing to but the diameter of circle knot is less than the spacing of outside two spring bigger than two spring distances of inner side, its purpose is that the speed shunk by rope reduces.Last baffle plate and the spring in outside play a cushioning effect.

Open drive motor, drive motor drives driving gear to rotate, driving gear is controlled by pneumatic shuttle, when drive motor imbalance or escape personnel are due to the excessive back drive driving gear stall of weight, guaranteeing that the rotating speed of driving gear is maintained at rational state, causing escape personnel Russia secondary injury thus being prevented effectively from.

Its operation principle is as follows:

Retarder parts has two-stage to accelerate, and accelerate multiple is 2.4 times every time, accelerates 5.76 times altogether, rope is rotated axle and is connected with driving gear by decelerator, and the bent axle being positioned on driving gear disk moves in a circle, bent axle is connected with piston by connecting rod, and circular motion then becomes rectilinear motion.

The present embodiment adopts fluid damping formula principle, if adopting spring to play the effect of resistance, knows that resistance is relevant with the displacement of decline according to Hooke theorem, and the more big resistance of displacement is more big, it is also possible to rebound before landing, purpose at the uniform velocity when simultaneously can not reach decline. Because the time is long during friction, coefficient of friction can float to some extent, and performance is less stable also, and gas flow damping formula is to utilize gas flow damping that the transform gravitational energy of human body is become the heat energy of gas, and speed so can be made to reduce. Owing to the size of air damping depends on outer load, no matter so the size of body mass all can decline with the speed (the design decrease speed is for 2.5m/s) of relative constancy.

Fluid cylinder internal diameter is 3.5cm, and external diameter is 4cm, fluid cylinder height 4.5cm, and piston range of activity is 4cm, length of connecting rod 4.5cm. The cross-sectional area of cylinder is 9.61cm2, and owing to cylinder inner wall and piston space have air channel, therefore piston area is decided to be 9.60cm2.

The cylinder that this escape machine adopts is similar to common piston cylinder, the difference is that the two ends of cylinder all take to seal, a certain amount of gas is inside had to play damping action, air channel is had between piston and barrel, piston have individual to recessed rubber cup. when pulling up piston, volume of air below piston increases, pressure reduces, air above piston is just extruded into lower section from rubber cup surrounding. when being pressed downward against piston, piston lower air volume-diminished, pressure increases, rubber cup is made not allow air drain to above piston tight against barrel, continue to be pressed downward against piston, this creates the terminal resistance makes velocity variations tend to uniform and stable, there is cushioning effect. according to fluid mechanics knowledge it can be seen that such design is conducive to the purpose reached at the uniform velocity. be computed, for 70kg(Chinese women average weight: 56.70kg, Chinese male average weight: 65.77kg) people just at the uniform velocity glide with the speed of 2.5m/s. one end of piston is connected with crank rocker. so, the rotary motion of crank is transformed into the rectilinear motion of piston, and energy is by the kinetic energy that liquid turns is heat energy and fluid, and this design has two cylinders, and its position is at an angle of 90.

Adopt such tectonic sieving, both reduced the carrying that single cylinder bears, it is possible to the size making cylinder will not be very big, makes the structure within escape machine more rationalize. Also effectively solving crank is rotating to the problem that extreme position hourly velocity easily fluctuates simultaneously. The multistage transmission of accelerating part can effectively solve the problem that speed easily fluctuates, and is that the speed declined is more stable.

The speed control of the present embodiment is this device core link, although the structure of this part is relatively easy, but very practical, can automatically by speed controlling at 2.5m/s.

Main by: slotted disk, centrifugal-block, spring and frictional groove are constituted, its structure as shown in drawings:

Disc radius is 7cm, and device of spring stiffness coefficient is 351.1N/m, and each mass body (includes coasting body and connecting rod), and quality is 18g. When speed is 2.5m/s, F (r=7cm)=94.95N.

On slotted disk, average mark is furnished with three guide grooves, a mass is had in each groove, mass can do rectilinear motion along radial direction while moving in a circle, one end spring of mass is connected on disc centre axle, the trapezoidal block rubber that the contact jaw of mass and frictional groove coincide with frictional groove equipped with shape, stops the increase of speed by increasing friction force.

Speed control principle: centrifugal principle

Analyze:

1. when disk is static

Spring is in natural length not by pulling force, and controlled valve resistance is 248.84N, and now mass does not move out.

2. during disc rotary

Mass has the trend outwards flown away from, increase with disc rotation speed, centrifugal force also increases, when disc rotation speed reaches 2039r/min, mass centrifugal force is just greater than switch valve resistance, and the pressure of mass outwards, is further increased friction from interior becoming after swinging out by switch valve connecting rod, making disk slow down rapidly, now spring is in extended state. When decrease speed reduces to 2.5m/s, the centrifugal force of mass is made a concerted effort less than the pulling force of spring, spring contraction with connecting rod, and mass is pulled inner side, and mass returns to previous status. If disk speed increases again, connecting rod is just again turned on, and mass is again so as to slow down, and so repeatedly, the speed of disk is just controlled in 2.5m/s, reaches the purpose of speed stabilizing.

The description of such scheme is the invention being understood that for ease of those skilled in the art and using. Embodiment obviously easily can be made various amendment by person skilled in the art. Therefore, the invention is not restricted to above-mentioned solid yardage case, those skilled in the art's the method according to the invention, the improvement made without departing from scope and amendment all should within protection scope of the present invention.
