Detailed description of the invention
Embodiment of the present utility model: the accelerator structure of a kind of high-rise circulation escape device, as shown in drawings, including circulation escape device 3, at least 2 grades of decelerators 15 are set in circulation escape device 3, the outfan of this decelerator 15 is connected with rope rotary shaft, driving motor 16 to engage realization with the upper driving gear 19 of decelerator 15 drives motor 16 to drive decelerator 15 to rotate, concentric disk 20 is set in the side of driving gear 19, the operative end surface of disk 20 arranges fixing axle 21 and this fixing axle 21 is positioned at side, disk 20 axle center, at least one pneumatic shuttle 22 one end is enclosed within fixing axle 21, on the support 23 of the circulation escape device 3 that the other end is hinged on disk 20 surrounding.
This fixing axle 21 arranges one, each pneumatic shuttle 22 connects end and is enclosed within fixing axle 21, this pneumatic shuttle 22 is positioned on the parallel surface parallel from disk 20 space and each pneumatic shuttle 22 is all located at different parallel surfaces, and pneumatic shuttle 22 includes sealing cylinder 24, piston 25 is arranged in sealing cylinder 24, connecting rod 26 one end connects in the middle part of piston 25, the other end stretches out sealing cylinder 24, connect end at connecting rod 26 and sleeve 27 is set and this sleeve 27 is enclosed within fixing axle 21, air channel 28 is set at sealing cylinder 24 inwall.
Time specifically used
Open driving motor, motor is driven to drive driving gear to rotate, driving gear is controlled by pneumatic shuttle, driving gear stall is driven due to the excessive back of weight when driving motor imbalance or escape personnel, guarantee that the rotating speed of driving gear is maintained at rational state, thus be prevented effectively from and cause escape personnel Russia secondary injury.
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 rotary shaft 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 linear motion.
The present embodiment uses fluid damping formula principle, if using spring to play the effect of resistance, knows that resistance is relevant with the displacement of decline according to Hooke theorem, and the biggest resistance of displacement is the biggest, 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, performance also less stable, 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 as 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 set to 9.60 cm2.
The cylinder that this escape machine uses is similar to common piston cylinder, except for the difference 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, have individual to recessed rubber cup on piston. the when of pulling up piston, volume of air below piston increases, pressure reduces, air above piston is just extruded into lower section from rubber cup surrounding. the when of 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, such it is designed with the purpose being beneficial to reach 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 linear motion of piston, and energy is by the kinetic energy that liquid turns is heat energy and fluid, and this is designed with two cylinders, and its position is at an angle of 90.
Use 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.The most effectively solve the problem that crank speed when rotating to extreme position 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 description of such scheme is the utility model 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, this utility model is not limited to above-mentioned solid yardage case, and those skilled in the art should be within protection domain of the present utility model according to method of the present utility model, the improvement made without departing from this utility model category and amendment.
