The corresponding support wheel 12 top cocked position in main hook 2 bottom sides are provided with cushion block 3.
Elaborate below in conjunction with the implementation step of accompanying drawing to the utility model.
See Fig. 2; Be that the utility model is hung into the step 1 structural representation; Push-and-pull cylinder hook 6 moves to vehicle frame 1 under the effect of push-and-pull cylinder, and when the friction inclined-plane of main hook 2 N contacted with the friction inclined-plane M of push-and-pull cylinder hook 6, main hook 2 received promotion and the guide effect of friction inclined-plane M; Rotate counterclockwise around bearing pin 1, push-and-pull cylinder hook 6 continues to move to vehicle frame 1;
See Fig. 3; Be that the utility model is hung into the step 2 structural representation, when the friction inclined-plane of main hook 2 N separates with the friction inclined-plane M of push-and-pull cylinder hook 6, main hook 2 will clockwise rotate around bearing pin 1 under the gravity effect; Main hook 2 stops because of position-limited rack 4 hinders, and main hook 2 is for hanging state;
See Fig. 4; Be the utility model unhook step 1 structural representation, push-and-pull cylinder hook 6 continues to move to vehicle frame 1 under the effect of push-and-pull cylinder, when the friction inclined-plane of top iron 5 P contacts with the friction inclined-plane M of push-and-pull cylinder hook 6; Under the promotion and guide effect of friction inclined-plane M; Main hook 2 rotates counterclockwise around bearing pin 1, and meanwhile push-and-pull cylinder hook 6 is continuing after vehicle frame 1 moves a bit of distance under the effect of push-and-pull cylinder, and the end face of pull bar 7 contacts with the lower end surface of push-and-pull cylinder hook 6; And under the promotion of push-and-pull cylinder hook 6, move and make and compress spring one 10 compressions; Drive ratchet 8 promotion ratchets 11 through bearing pin 3 15 simultaneously and clockwise rotate around bearing pin 2 14, when push-and-pull cylinder hook 6 end faces contact vehicle frame 1, the displacement of pull bar 7 makes ratchet 8 promote ratchets 11 just and clockwise rotates 45 ° around bearing pin 2 14; Because the connection fixation of key 16 makes support wheel 12 and ratchet 11 rotate 45 ° synchronously, push-and-pull this moment cylinder hook 6 can promote vehicle frame 1 motion;
Seeing Fig. 5, is the utility model unhook step 2 structural representation, when vehicle frame 1 moves to assigned address; Push-and-pull cylinder hook 6 retracts with stop motion and under the effect of push-and-pull cylinder; Pull bar 7 drove ratchet 8 down in the effect of compression spring 1 and resetted this moment, and ratchet 11 does not rotate with 12 of support wheels, and while main hook 2 is under the guide effect of the friction inclined-plane M of the friction inclined-plane P of gravity and top iron 5 and push-and-pull cylinder hook 6; Clockwise rotate around bearing pin 1; When pull bar 7 separated with the end face of push-and-pull cylinder hook 6, after push-and-pull cylinder hook 6 continues to retract a bit of distance, just moved with one of the top of support wheel 12 contact stop in cushion block 3 bottom surfaces that are fixed on the main hook 2; This moment, the gib head height of main hook 2 can make push-and-pull cylinder hook 6 retract smoothly, and this state is the unhook state;
See Fig. 6; Be that the utility model is hung into the step 1 structural representation again, for realizing automatic coupling, push-and-pull cylinder hook 6 moves to vehicle frame 1 under the effect of push-and-pull cylinder; When the friction inclined-plane of top iron 5 P contacts with the friction inclined-plane M of push-and-pull cylinder hook 6; Receive promotion and the guide effect of friction inclined-plane M, main hook 2 rotates counterclockwise around bearing pin 1, and meanwhile push-and-pull cylinder hook 6 is continuing after roll change vehicle frame 1 moves a bit of distance under the effect of push-and-pull cylinder; The end face of pull bar 7 will contact with the lower end surface of push-and-pull cylinder hook 6; And under the promotion of push-and-pull cylinder hook 6, move and make one 10 compressions of compression spring, drive ratchet 8 promotion ratchets 11 through bearing pin 3 15 simultaneously and clockwise rotate, when push-and-pull cylinder hook 6 end faces contact vehicle frame 1 around bearing pin 2 14; The distance that pull bar 7 moves is to make ratchet 8 promote ratchet 11 to clockwise rotate 45 ° around bearing pin 2 14 just, because the connection fixation of key 16 makes support wheel 12 and ratchet 11 rotate 45 ° synchronously;
See Fig. 7; Be that the utility model is hung into the step 2 structural representation again, push-and-pull cylinder hook 6 retracts under the effect of push-and-pull cylinder, and pull bar 7 this moment drive ratchet 8 under one 10 effects of compression spring resets; Ratchet 11 is motionless with 12 of support wheels; Simultaneously main hook 2 clockwise rotates around bearing pin 1 under the guide effect of the friction inclined-plane M of the friction inclined-plane P of gravity and top iron 5 and push-and-pull cylinder hook 6, stops up to receiving position-limited rack 4 obstructions; Support wheel 12 two tops between, hang into state just by the realization secondary for cushion block 3 at this moment.
