Left side.
The working principle of the invention is: when storing small-sized pipe fitting using the present apparatus, by the small-sized pipe fitting of different model from L shape
At the inlet push-in movable plate 5-12 of shell 5-1, pipe fitting enters in movable plate 5-12 when moving, and first III 5-9 of pressure rod makes bar
III 5-9 is tilted to the mobile direction of pipe fitting, when III 5-9 of bar is moved to bottom, III 5-9 pressure rod of bar IV 5-16, IV 5-16 of bar
It is moved down in II 5-14 of slot, and one end of IV 5-16 driven rod of bar, II 5-7 moves down, in II 5-14 inner-support of slot
Under effect, the other end of II 5-7 of bar is upturned, and I 5-6 of tilting end driven rod of II 5-7 of bar is moved up, and I 5-6 of bar, which drives, to be slided
II 5-5 of bar is moved up, and II 5-5 of slide bar drives movable block 5-3 to move up, and your movable block 5-3 compressed spring, movable block
5-3 band dynamic pressure plate 5-10 move up, make the distance between pressing plate 5-10 and movable plate 5-12 bottom plate increase, facilitate pipe fitting into
Enter, after pipe fitting is detached from III 5-9 of bar, III 5-9 of bar is moved back to original position under the action of V 5-13 of spring, makes pressing plate 5-10 to moving down
It is dynamic, pipe fitting is clipped between movable plate 5-12 and pressing plate 5-10, pipe fitting play is prevented;When storing the large-size pipe of different model,
Pipe fitting is placed on fixed plate 1-1, then by one end insertion jack 1-5 of U-shaped bar 1-3, the other end of U-shaped bar 1-3 is put
Enter inside pipe fitting, starts motor 1-6, motor 1-6 band I 1-2 of moving gear is rotated, and then drives conveyer belt 1-4 movement, conveyer belt 1-
4 drive U-shaped bar 1-3 movement, and one end of U-shaped bar 1-3 is stuck in inside pipe fitting, and U-shaped bar 1-3, conveyer belt 1-4 drive pipe fitting to moving up
It is dynamic, when pipe fitting is moved to the shell inlet 2-1, U-shaped bar 1-3 is removed, then pipe fitting is pushed on fixed device 2-8,
When pipe fitting and fixed device 2-8 are contacted, I 2-8-3 of curved rod is first contacted with pipe fitting, and pipe fitting continues to move to, and presses I 2-8- of curved rod
3 slide around fixed block 2-8-2, block I 2-8-3 of curved rod, II 2-8-5 of curved rod by pipe fitting, then push fixed device
2-8, when pushing fixed device 2-8 mobile, I 2-2 of vibration damper plate is rotated around hinge, after pipe fitting is moved to right end, vibration damper plate I
2-2 moves back to original position under the effect of gravity, and avoiding mutually colliding between pipe fitting causes pipe fitting to damage;When mobile pipe fitting, it will convey
Device 1 turns to the left end of shell 2-1 around hinge, avoids falling in pipe fitting moving process, then pulls I 3-4 of slide bar, slide bar
I 3-4 compressed spring, I 3-3, and I 3-4 of slide bar drives connecting rod 3-5 mobile, and connecting rod 3-5 drives inserted link 3-6 in card slot 4-6
Interior movement, and inserted link 3-6 is detached from II 4-5 of gear, and wheel 4-4 is enable to move freely, and after being moved to destination, unclamps slide bar I
3-4, I 3-4 of slide bar drive inserted link 3-6 to be stuck on II 4-5 of gear, avoid chassis 4 arbitrarily mobile.
