Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
As shown in Figure 1, small size automatic multi-stage expansion lever apparatus of the present invention, comprises an expansion link cylinder, the movable cylinder 9 that expansion link cylinder comprises stationary magazine creel 6 and runs through its inner chamber and can stretch along it, expansion link cylinder is connected with controller 4, and controller 4 connects gas-holder 3 to direct current air pump 1 by air pipe line 2; The inner chamber cover of movable cylinder 9 has can be along its flexible load platform 11; Stationary magazine creel 6 is provided with the carry-over pinch rolls 5 that drive by direct current generator 21, and carry-over pinch rolls 5 are provided with the haulage cable 8 joining with load platform 11.
Under controller 4 is controlled, the pressurized air of gas-holder 3 passes in stationary magazine creel 6 and movable cylinder 9 by air pipe line 2, and air pressure driving activity cylinder 9 along continuous straight runs eject fast; Direct current air pump constantly supplements cylinder pressure, the state that stretches out of maintenance activity cylinder 9; After load platform 11 has been surveyed, when withdrawal, under the control of controller 4, close direct current air pump 1, discharge the pressurized air in cylinder, direct current generator 21 pulls haulage cable 8 drive activity cylinders 9 one successively to regain by carry-over pinch rolls 5, until all movable cylinders 9 are got back to initial position (the spacing position of stationary magazine creel), close direct current generator 21 by controller 4, complete noncontact quick detection one time.
As shown in Figure 2, in this device, movable cylinder 9 is that the multistage movable cylinder that external diameter is socketed from large to small successively forms, movable ascending progressively assembling, and what diameter was little penetrates the movable cylinder that diameter is large, after passing, returns to stop collar 10 at movable little front end dress.Movable cylinders 9 at different levels socket-connect to hold and are respectively equipped with male half coupling 14 and inner stopper 16, between male half coupling 14 and movable cylinder 9 inwalls, are provided with O-ring seal, and inner stopper 16 is provided with and returns to stop collar 10, returns to stop collar 10 and is provided with elastic spring 15.Return to stop collar 10 and be made up of two semi-circular structure, easy disassembly activity cylinder, returns to stop collar 10 and is provided with in the groove that inner convex platform is stuck in movable cylinder 9 outer ends, and elastic spring 15 is stuck in the outer wall groove that returns to stop collar 10.The movable cylinder adapted different size of different-diameter return to stop collar and elastic spring.Between the movable cylinder 9 of two joints and movable cylinder 9 and stationary magazine creel 6 end that socket-connects be provided with successively from the inside to the outside radial direction seal ring 12 and end-face seal ring 13.This radial direction seal ring finishes all to seal at movable cylinder push and release.The end-face seal ring 13 of movable cylinder seam tail end seals in the time that movable cylinder 9 is shifted onto, and push is inoperative.In stationary magazine creel 6, in sealing state, be equivalent to cylinder piston at the movable cylinder 9 of stationary magazine creel 6 inside.
The movable cylinder 9 being connected with load platform 11 only has male half coupling 14, and all the other movable cylinders 9 have male half coupling 14 and inner stopper 16.The joint number of movable cylinder 9, in range claimed range, can increase or reduce according to the needs of flexible stroke, does not need other structures of change system.
The system speed of stretching out can be passed through volume and the gaseous tension control of gas-holder 3, and withdrawal speed can be by the rotating speed of direct current generator 21, ratio of gear, the ratio of gear of transmission gear 20 and the diameter control of carry-over pinch rolls 5 of speed reduction unit 23.
As shown in Figure 3, Figure 4, direct current generator 21 is located on the sidewall of the stationary magazine creel 6 in expansion link cylinder, direct current generator 21 is connected with transmission gear 20, and transmission gear 20 connects the carry-over pinch rolls 5 that are wound with haulage cable 8, and haulage cable 8 is connected to the load platform 11 connecting on outermost activity cylinder 9.Gas-holder 3 is supported on ground by base 7, is respectively equipped with pressure gauge 19 and limit switch 18 on gas-holder 3, and controller 4 is located on gas-holder 3 sidewalls.
As shown in Figure 5, stationary magazine creel 6 is provided with stationary magazine creel press strip 17 with movable cylinder 9 link periphery walls.
The material that stationary magazine creel 6 of the present invention is selected is high-strength aluminum alloy 7075-T6, and movable cylinder 9 materials of selecting are T300 carbon fiber.
System of the present invention can be mounted on the motion platforms such as vehicle, naval vessel, aircraft easily by the coupling arrangement of base 7.
After system boot, receive after enabling signal when system, direct current air pump 1 starts, and opens gas-holder 3 operation valves by controller 4, and the pressure in gas-holder 3 reaches after setting value through pressure gauge 19 tests, and direct current air pump 1 stops.System is received after startup command, open gas filling valve by controller 4, now pressurized air is led in expansion link cylinder (comprising stationary magazine creel 6 and movable cylinder 9) by air pipe line 2 by gas-holder 3, movable cylinder 9 ejects fast under gaseous tension drives, and haulage cable also ejects with the movable cylinder of expansion link; When movable cylinder is released fast, jaw clutch 22 is in disengaged condition, and direct current generator 21 is not worked.Carry-over pinch rolls rotate under the traction of the movable cylinder of first segment by wire rope, and wire rope launches gradually from carry-over pinch rolls; Expansion link arrives behind precalculated position, according to the air pressure signal of gas-holder pressure gauge feedback, controls gas-holder valve, keeps expansion link cylinder internal gas pressure constant, maintains expansion link and ejects state, and direct current air pump supplements air pressure according to the pressure size not timing in gas tank.It is the sealing of environment that radial direction seal ring 12 and end-face seal ring 13 can ensure in expansion link cylinder, prevents gas leak.Movable cylinder 9 arrives behind precalculated position, and the pressure signal that controller 4 feeds back according to barometer 19 is controlled direct current air pump 1 and made the air pressure in expansion link cylinder keep constant, maintains the ejection state of expansion link cylinder.
Detection operations completes, and system is received and regained after order, closes gas-holder operation valve by controller, open gas bleed valve, discharge gas in expansion link cylinder, make expansion link cylinder inside and atmosphere conducting, the pressurized air of discharge expansion link cylinder inside is to atmospheric pressure, and expansion link cylinder internal gas pressure is identical with atmospheric pressure.Jaw clutch adhesive, DC speed-reducing slow start, drives carry-over pinch rolls to be wound around and retracts haulage cable, and the movable cylinder of expansion link is lived and is started progressively to reclaim from first segment; The recovery stop collar of the movable cylinder of first segment front end drives the movable cylinder of second section to reclaim.All the other movable cylinders of same method reclaim successively, until the movable cylinder of first segment arrives the limit-switch positions on stationary magazine creel, and now pulling motor braking, throw-out-of clutch, recovery system quits work.
