Driving cylinder 10 promotes speedup pulley 15 pulling strands and draws steel cable 17, but produces the power that initially pulls of accuracy control speed; Strand draws steel cable two-way reel 21 of pulling after leading sheave 18 and rope guide 19 guiding to quicken rotation with controlled rate, and rotation function is passed to down ahead running change-speed box 30 through transmission shaft 24, reel power-transfer clutch 25, and described reel power-transfer clutch is positive terraced fluted disc power-transfer clutch; The ahead running change-speed box is with the transmitting ratio set with turn to outputting power, launch reel 35 rotations by a pair of universal coupling 33 and 34 drivings of reel power-transfer clutch, strand draw launch be with 37, pulling coaster 69, supratrochlear carrier aircraft hook 70 articulates hauling hook 95, hauling hook pulling carrier-borne aircraft 94 sliding race on flight deck; Launching the end of slide rail, the band hook 71 that launches of coaster separates under the pressure effect at sloping 82 places of breaking off relations with the peg that launches that launches band, and carrier-borne aircraft is greater than minimum flying speed, take off with the initial angle of setting; Coaster 69 bump gas pistons 85 and buffering spring 88 slow down and bounce-back, a plurality of coasters in the two side of launching slide rail power-assisted wheel 89 that resets rotates, promote coaster by friction force and get back to the starting end that launches slide rail 68 with the coaster sidewall, stop and be parked in the starting position by side pressure slipper 77 braking, prepare to launch next time by electromagnet 76 absorption.
Launch reel and draw coaster in strand, can realize the effect that coaster gradually quickens with launching the band applied in any combination; Under recoil spring and coaster resetted the combined action of power-assisted wheel, coaster can be realized resetting fast.
In ejection process, need to use pinch roller 43 and retinue to drag to make 52 avoid launching be with 37 and reset backguy 51 with launch slide rail 68 and rub, the retinue that is provided with electromagnetism backguy locker is dragged and is made 52 to have the reset function of backguy 51 of locking and release; Drag when retinue and to make 52 during at starting end, pinch roller 43 and Rocker arm 44 are in extreme lower position and locked, retinue is dragged and is made the 52 locking backguys 51 that reset, and launches reel 35 strands and draws and hang with launching of coaster 69 and be with 37, making retinue drag order to make slide rail 53 ahead runnings with the backguy 51 that resets along dragging; Moving to the cunning of launching slide rail 68 at coaster 69 jumps up when locating, governor valve 49 is opened, by launching with tension force lifting pinch roller 43 and Rocker arm 44 on 37, Rocker arm 44 presses pressure zone oil cylinder 46 by backguy and pulley 47, and the oil in the pressure zone oil cylinder enters hydraulic accumulator 50 through pipeline and governor valve 49; The uplift rate of pinch roller 43 is by governor valve 49 controls, and pinch roller 43 is raised to vertex before coaster 69 walks to sloping 82 places of breaking off relations; Launch in the slide rail the sliding retinue of jumping up when locating and drag and make 52 touching limit switches 60 when coaster 69 moves to, retinue this moment drags order to discharge the backguy 51 that resets, and the backguy that resets is dragged in the order in retinue walk; Retinue drags order to collide described moving ahead subsequently to stop block 61 and stop to move ahead; Launch be with 37 with coaster 69 after sloping 82 places of breaking off relations separate, launch with the tension force on 37 and reduce, hydraulic oil in the hydraulic accumulator 50 is refluxed enter pressure zone oil cylinder 46, pinch roller 43 falls after rise, close when pinch roller 43 falls to the extreme lower position governor valve 49 after rise, the position of pinch roller 43 is locked; The motor 65 that resets starts, and drives the cylinder 62 that resets by fluid coupling 64 and rotates, and cylinder 62 strands that reset are drawn the backguy 51 that resets, and retinue is dragged and made 52 to get back to the starting end that launches slide rail.
Fly on the deck sliding jumping up, pinch roller and retinue drag order can avoid launching band and reset backguy with launch slide rail and rub, pinch roller can be installed on the horizontal take-off deck and accompany to drag and make and relevant equipment.
After driving cylinder 10 is finished the promotion of once launching, energy storage change-over valve 6 and oil cylinder change-over valve 7 are closed being connected of energy storage 8 and driving cylinder 10, oil cylinder change-over valve 7 is communicated with driving cylinder 10 and drains the oil pipeline 5-3, and driving cylinder 10 is drained the oil, piston reclaims, and plays the buffer shock-absorbing effect simultaneously.
Use ahead running change-speed box and two-way reel that the unidirectional rotation of reel is once finished to drive to launch reel and reclaim and twine the operation that strand is drawn steel cable, drive to launch reel and reclaim next time and twine the operation opposite spin that strand is drawn steel cable, make by ahead running change-speed box and to launch reel and rotate with the direction of pulling coaster, thereby shortened the setup time of launching between the operation for twice, realized that high frequency launches.Can catapult-assisted take-off runway more than one be set at the naval vessel flight deck, but the output shaft at both ends of ahead running change-speed box 30 respectively drives one and launches reel (as Fig. 1,35 and 35-1), constitutes two ejectors; Further, respectively drive ahead running change-speed box at the two ends of two-way reel 21, each the ahead running change-speed box drive two and launch reel, can constitute maximum four ejectors, further improve and launch frequency.
When strand is drawn steel cable 17 when pulled, strand draw steel cable tension force drive the position telescopic moving that the conductor rope axle of rope guide 19 draws steel cable with strand, promote 99 compressions of conductor rope cylinder, compressed gas enters low pressure accumulator 100 through pipeline; When launch finish after, strand draws steel cable 17 to lose tension force, pressure gas in the low pressure accumulator 100 is back to conductor rope cylinder 99 along pipeline, and the conductor rope cylinder promotes the conductor rope axle counter motion of rope guide 19, and rope guide guiding strand draws steel cable to be wrapped in proper order on the two-way reel 21 with the helix line form.
The utility model adopts mature industrial manufacturing technology, and manufacture difficulty is low, and cost is low, and can be applicable on the recreational facilities, as roller coaster.
