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, and expansion link cylinder comprises stationary magazine creel 6 and runs through its inner chamber and the movable cylinder 9 that 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 along its flexible load platform 11; Stationary magazine creel 6 is provided with the carry-over pinch rolls 5 driven by direct current generator 21, and carry-over pinch rolls 5 are provided with the haulage cable 8 connected with load platform 11.
Under controller 4 controls, 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 ejects in the horizontal direction fast; Direct current air pump constantly supplement cylinder pressure, maintenance activity cylinder 9 stretch out state; After load platform 11 has detected, during withdrawal, under the control of controller 4, close direct current air pump 1, pressurized air in release cylinder, direct current generator 21 pulls haulage cable 8 drive activity cylinder 9 one successively to regain, until initial position (stationary magazine creel restraining position) got back to by all movable cylinders 9 by carry-over pinch rolls 5, close direct current generator 21 by controller 4, complete a noncontact quick detection.
As shown in Figure 2, in this device, the multistage movable cylinder that movable cylinder 9 is socketed from large to small successively for external diameter is formed, and movable cylinder is ascending progressively to be assembled, and what diameter was little penetrates the large movable cylinder of diameter, returns stop collar 10 after passing at little movable cylinder front end dress.The movable cylinder 9 at different levels end that socket-connects is respectively equipped with male half coupling 14 and inner stopper 16, and be provided with O-ring seal between male half coupling 14 and movable cylinder 9 inwall, inner stopper 16 is provided with and returns stop collar 10, returns stop collar 10 and is provided with elastic spring 15.Return stop collar 10 to be made up of two semi-circular structure, easy disassembly activity cylinder, return stop collar 10 and be provided with inner convex platform and be stuck in the groove of movable cylinder 9 outer end, elastic spring 15 is stuck in and returns in the outer wall groove of stop collar 10.The movable cylinder adapted different size of different-diameter return stop collar and elastic spring.Between the movable cylinders 9 of two joints and movable cylinder 9 socket-connect to hold with stationary magazine creel 6 and be provided with radial direction seal ring 12 and end-face seal ring 13 from the inside to the outside successively.This radial direction seal ring terminates all to seal at movable cylinder push and release.The end-face seal ring 13 of movable cylinder seam tail end seals when movable cylinder 9 is shifted onto, and push is inoperative.Be in sealing state in stationary magazine creel 6, be equivalent to cylinder piston at the movable cylinder 9 of stationary magazine creel 6 inside.
The movable cylinder 9 be 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 according to the needs of flexible stroke or reduce, not need other structures of change system.
The system speed of stretching out can by the volume of gas-holder 3 and gas Stress control, and speed of regaining can by the diameter control of the rotating speed of direct current generator 21, the ratio of gear of speed reduction unit 23, the ratio of gear of transmission gear 20 and carry-over pinch rolls 5.
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 being wound with haulage cable 8, and haulage cable 8 is connected to the load platform 11 that outermost activity cylinder 9 connects.Gas-holder 3 is supported on ground by base 7, gas-holder 3 is respectively equipped with pressure gauge 19 and limit switch 18, and controller 4 is located on gas-holder 3 sidewall.
As shown in Figure 5, stationary magazine creel 6 and movable cylinder 9 link periphery wall are provided with stationary magazine creel press strip 17.
The material that stationary magazine creel 6 of the present invention is selected is high-strength aluminum alloy 7075-T6, and the material that movable cylinder 9 is selected is T300 carbon fiber.
Present system can be mounted on the motion platforms such as vehicle, naval vessel, aircraft easily by the coupling arrangement of base 7.
After system boot, after system receives enabling signal, direct current air pump 1 starts, and opens gas-holder 3 operation valve by controller 4, and until the pressure in gas-holder 3 after pressure gauge 19 test reaches setting value, direct current air pump 1 stops.After system receives startup command, gas filling valve is opened by controller 4, now pressurized air leads in expansion link cylinder (comprising stationary magazine creel 6 and movable cylinder 9) by gas-holder 3 by air pipe line 2, 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 does not work.Carry-over pinch rolls are rotated under the traction of the movable cylinder of first segment by wire rope, and wire rope launches gradually from carry-over pinch rolls; After expansion link arrives precalculated position, according to the air pressure signal of reservoir pressure meter feedback, control gas-holder valve, keep expansion link cylinder internal gas pressure constant, maintain expansion link and eject state, direct current air pump supplements air pressure according to the pressure size not timing in gas tank.Radial direction seal ring 12 and end-face seal ring 13 can ensure it is the sealing of environment in expansion link cylinder, prevent gas leak.After movable cylinder 9 arrives precalculated position, the pressure signal that controller 4 feeds back according to barometer 19, controls direct current air pump 1 and makes the air pressure in expansion link cylinder keep constant, maintain the ejection state of expansion link cylinder.
Detection operations completes, and system closes reservoir control valve by controller after receiving and regaining order, open gas bleed valve, gas in release expansion link cylinder, makes expansion link cylinder inside and air 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 work of expansion link is progressively reclaimed from first segment; The recovery stop collar of the movable cylinder front end of first segment 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, now pulling motor braking, throw-out-of clutch, recovery system quits work.
