The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in Fig. 1,2,3, be integral structure figure, Non-return idler two ends symmetry is equipped with bearing seat 6,12, bearing 7,13, is hermetically-sealed construction in the bearing seat 6,12, is sealed by seal ring 11,17 respectively, and lubricating oils want sufficient in the bearing 7,13, to guarantee that rotation flexibly.
Back-stop mechanism 5 is contained on the roll shaft 2, by identical connection of check steel ball 26 location of diameter 8mm, roll shaft 2 is provided with circular arc steel ball groove, also be provided with circular arc steel ball groove 29 on the ratchet 20 of back-stop mechanism 5, assembling back check steel ball 26 is just in time packed in steel ball groove 29 on the ratchet 20, the steel ball groove on the roll shaft 2, and it is fixing to coincide; It is fixing by back-up ring 34,35 that back-stop mechanism 5 is contained in roll shaft 2 backs; Back-stop mechanism 5 connects with welding block 27,28 in the roller skin 3 in roller chamber 4, and back-stop mechanism 5 is rotated with roll body 1.
Shown in Fig. 4,5, be back-stop mechanism 5 constructionals drawing, 22,23,24,25,4 chain sheets 36,37,38,39 of back-stop mechanism 5 outside uniform 4 blocks, chain sheet 36,37,38,39 is fixing by bearing pin 30,31,32,33; Be provided with ratchet 20 in the centre of back-stop mechanism 5, in the middle of the ratchet 20 is axis hole 21, steel ball groove 29, and ratchet 20 is biparting shape, contacts reef with chain sheet 36,37,38,39 during mode of operation, during the forward running, ratchet 20 does not contact with chain sheet 36,37,38,39, and when antiport, chain sheet 36,37,38,39 blocks ratchet, back-stop mechanism 5 can not be rotated, because of back-stop mechanism 5 and roller skin 3 combine as a whole, so roll body 1 can not be rotated, thus reach non-return effect.
The inventive principle of Non-return idler is:
Check steel ball 26 is contained in the steel ball groove of the steel ball groove 29 of ratchet 20 and roll shaft 2, because of roll shaft 2, ratchet 20 does not rotate with load-transfer device, back-stop mechanism 5 and roller skin 3 are by welding block 27,28 is integrally welded, so back-stop mechanism 5 rotates with the rotation of roller skin 3, the block 22 of back- stop mechanism 5,23,24,25 are provided with groove, chain sheet 36,37,38,39 are hinged on the block, and when the belt conveyer forward rotation, back-stop mechanism is forward rotation also, rotating under the centrifugal action, the chain sheet abuts against in the block groove, when load-transfer device reverses, during broken belt, the load-transfer device inverted running, by gravity, the chain sheet breaks away from groove, and after the chain sheet was run into ratchet 20, ratchet 20 just pinned the chain sheet, stop the back-stop mechanism backward rotation, carrying roller stops operating simultaneously, and the load-transfer device on the carrying roller becomes slip by rolling, thereby has played the purpose of check.
Notice during installation that the center-of-gravity position of chain sheet on block is correct, will rotate between chain sheet and the bearing pin flexibly that dirt must not be arranged.
