Detailed description of the invention
As shown in Figure 1 and Figure 2, for simulates real Altitude short-circuit test fifth wheel releasing device of the present inventionStructure chart, it is by power transmission shaft 2, upper trigger 3, slide block 4, trigger block 5, support 6, lower triggeringDevice 7, cantilever 8, connecting rod 9, trigger 10, trigger block 11, fifth wheel carrier block 12, short circuit simulationCarrier 13, trigger limited block 14, rotational pin 15 and fifth wheel band motion block 17. Whole device can be placedIn vavuum pump, in the time that vavuum pump reaches predetermined vacuum level, can utilize external control button to control.
Support 6 is main bearing structure, the rotating shaft of the upper termination motor 1 of power transmission shaft 2, upper trigger 3 and underTrigger 7 is individually fixed in the upper and lower of support 6, and slide block 4 is installed on power transmission shaft 2, by changingThe rotation direction of power transformation machine 1 can make power transmission shaft 2 be with movable slider 4 to move up and down. Power transmission shaft 2 adopts and rollsBallscrew, changes into moving up and down of slide block by rotatablely moving of motor. Trigger block 5 and cantilever 8One end is fixed on slide block 4, and the other end of cantilever 8 and connecting rod 9 are fixing, and power transmission shaft 2 is with movable slider 4In the process moving up and down, trigger block 5 acts on upper trigger 3 or lower trigger 7, respectively controlMotor 1 change processed turns to or is out of service.
As shown in Figure 3, trigger block 11 is fixed on the another side of support 6, connecting rod 9 and transmissionAxle 2 is parallel and arrange near trigger block 11; Trigger 10 is fixed on connecting rod 9 by rotational pin 15And the untie-sell 15 that can rotate rotates, trigger limited block 14 is fixed on connecting rod 9 for limit trigger 10Slewing area, fifth wheel carrier block 12 is connected to the lower end of connecting rod 9.
Band motion block spring leaf 18 is fixed on connecting rod 9, and the top of fifth wheel carrier block 12 is left along connectingThe cavity of bar 9 radial arrangement, is equipped with fifth wheel 22 in described cavity, fifth wheel band motion block 17 is arranged on manyExcess carrier block 12 bottoms are also vertical in described cavity, leave through hole, for holding on fifth wheel band motion block 17Connect the fifth wheel 22 falling from described cavity, fifth wheel band motion block 17 can be at trigger 10 and band motion block spring leafUnder 18 acting in conjunction, horizontally slip along the bottom of fifth wheel carrier block 12, the bottom of fifth wheel carrier block 12Be provided with hopper zone, the fifth wheel 22 in fifth wheel band motion block 17 through holes is by the cunning of fifth wheel band motion block 17Moving described hopper zone the final short circuit mould that falls to being overlapped on to be positioned under fifth wheel carrier block 12 of falling intoIntend on carrier 13.
Trigger spring leaf 16 is fixed on connecting rod 9, many for preventing in the time not needing to discharge fifth wheel 22The effect of excess band motion block 17.
Fifth wheel carrier block 12 loads fifth wheel, formed by three parts, as shown in Figure 4, respectivelyFor left carrier block 19, right carrier block 21 and lower carrier block 20, three parts are by the bonding one-tenth fifth wheel of metal-to-metal adhesiveCarrier block 12. The left part of left carrier block 19 has groove and is combined into along connecting rod 9 with right carrier block 21The cavity of radial arrangement, left carrier block 19 bottoms and right carrier block 21 bottoms all have groove and with lower carryingPiece 20 is combined into the cavity horizontally slipping for fifth wheel band motion block 17, and the bottom of lower carrier block 20 hasHopper zone. Fifth wheel band motion block 17 can pull fifth wheel 22 to move, in the time moving to hopper zone, unnecessaryThing 22 will be released. Before being positioned over vavuum pump, can load multiple fifth wheels 22.
Press external control switch button, motor 1 and power transmission shaft 2 are with the downward rectilinear motion of movable slider 4, whenFifth wheel carrier block 12 moves to the top of short circuit analog carrier 13, and trigger 10 occurs with trigger block 11Effect, trigger 10 untie-sell 15 that rotates is rotated counterclockwise, and outwards promotes fifth wheel band motion block 17, fifth wheel bandMotion block 17 drives a fifth wheel 22 to enter into the hopper zone of fifth wheel carrier block 12, and fifth wheel 22 fallsBe discharged on short circuit analog carrier 13, as shown in Figure 5, Figure 6. At this moment, from the watch window of vavuum pump justPhenomenon can observe vacuum short circuit time.
Under fifth wheel, fall behind, trigger block 5 triggers lower trigger 7, controls motor 1 and reverses, and drives slidingPiece 4 and fifth wheel carrier block 12 move upward. Band motion block spring leaf 18 resets fifth wheel band motion block 17,Lay equal stress on and be newly loaded into fifth wheel 22. In the time that fifth wheel carrier block 12 rises to initial position, trigger block5 have an effect with upper trigger 3, control motor 1 and stop, and realize mechanism's protection and reset function automatically.In the time again pressing external control switch button, releasing device can move again, again discharges a fifth wheel
22。
The installing hole of trigger block 5 and trigger block 11 is split into elongated hole, can regulate their installationPosition, so just can regulate fifth wheel to fall time from the height of short circuit analog carrier 13.
The content not being described in detail in description of the present invention belongs to those skilled in the art's known technology.
