Embodiment
Further describe this patent below in conjunction with example, the present invention does not limit to and following examples.
A kind of compact shelving is shaken the hand transmission device, comprises the formations such as handle mechanism, driving mechanism, arrestment mechanism, mechanism for locking up.
As shown in Figure 1, Figure 3: this driving mechanism mainly contains scroll key formula two-way automatic clutching mechanism, brake transmission mechanism, upper braking lock mechanism, these mechanisms all concentrate to be contained in shakes the hand on wheel, realize transmission and control by concentric shafts, be contained in a few part compositions such as the Transmitted chains two-way slack list automatic tensioning mechanism on driver plate in addition.It includes fixed hollow shaft, the handwheel 1 be enclosed within hollow shaft 7, the clutch outer be contained in handwheel 1, the inner ring be enclosed within hollow shaft, be contained in scroll key 2 between the two and utilize the effect of deadweight to form scroll key formula bidirectional automatic clutch, crank handle during state of rest on handwheel 1 and scroll key 2 all rest on bottom, during passivity, transmission shaft 12 and handwheel 1 are thrown off automatically, and during active state, scroll key 2 makes inner ring, outer ring combines automatically.The other end of inner ring is sprocket wheel, the outside of handwheel 1 central authorities has stop knob 5, knob to drive keep plate to move to realize by the wig-wag spring 14 on brake axle and brake and the switching of non-brake state, knob is equipped with braking lock 4, rotation brake lock core drives inner cam pin 3, in the braking and locking groove turning to chuck 9, realize the upper braking lock of braking state.Be contained in above the wobble plate on driver plate 1 and two Idle wheels 20 are housed, rely on the acting in conjunction of Transmitted chains pilled-in selvedge and spring, realize slack list auto-tensioning.
As shown in Figure 4: adopt scroll key formula automatic bidirectional clutch mechanism: when state of rest, handwheel 1 is under the inclined Action of Gravity Field of handle, and handle is still in immediately below handwheel 1 gyration center.Now, immediately below the groove be contained on the clutch outer shroud in the middle part of handwheel 1 is also in, scroll key 2 is still in the lowest part in the middle of groove.When passive rotation (compact shelving moves and makes to be driven drive sprocket to rotate by movable sprocket), because scroll key 2 and the clutch inner ring on the axis of a movable block leave gap, so outer ring 11 can not be driven to rotate, handwheel 1 keeps static.When rotate handwheel 1 that is active rotation time, handwheel 1 drives the groove on outer ring 11 to rotate to side, and scroll key 2 rolls to lowest part under gravity.When groove forwards certain altitude to, scroll key 2 will contact with inner ring, be rotated further handwheel 1 drives outer ring 11 groove working surface to force scroll key 2 and inner ring close contact under the effect of wedge surface, now mechanism enters bonding state, the axis of a movable block will be driven to rotate, thus make compact shelving initiatively mobile operation, reach the object of transmission.After out of service, make handle return to original place, under the acting in conjunction of outer ring 11 groove and gravity, scroll key 2 also can auto-returned original position, and mechanism turns back to again original separated state.Be exactly: handle with sleeve combines automatically put back to handle and be automatically separated in brief, thus automatically combine when reaching initiatively, the object be automatically separated time passive.
As shown in Figure 5: when clutch inner ring is arranged to gear wheel, the keyway quantity be evenly distributed on inner ring can have influence in conjunction with angle, and it is less that quantity combines angle more.When quantity be increased to infinite many time, the external frame of inner ring has just developed into smooth cylndrical surface, and namely so-called halo, working procedure is similar to the above.Difference is for the former is lean on the screens of keyway to realize combining, and the latter realizes combining by the frictional force that the wedging angle of scroll key 2 is corresponding.Select suitable wedging angle can ensure to combine reliably non-slip, be separated and smooth and easyly do not kill.
This clutch mechanism, simple and reasonable, reliable, little in conjunction with angle, easy and simple to handle, run the advantages such as noise free.Effectively eliminate the operation noise of hanger type clutch mechanism, reduce in conjunction with angle, and mechanism is simplified most.
As shown in Figure 7, Figure 8: braking and upper braking lock mechanism: drive the crank of brake axle 6 the other end to be rotated down 90 ° clockwise by the clutch knob being arranged at handwheel 1 center, keep plate 16 is forced to move down, thus make the braking on keep plate 16 keep off the teeth groove leaving sprocket wheel, now mechanism is in non-brake state.Otherwise turning knob makes crank oppositely rotate up counterclockwise, keep plate 16 moves up under the effect of braking spring 17 elastic force, the force direction of braking spring 17 points to braking state, instead of non-brake state, keep plate 16 is forced to move to non-brake state upon rotation of the knob, during to prevent from braking, keep plate 16 and sprocket tooth pointed tooth, cause braking not complete smoothly.Braking gear on keep plate 16 moves to the direction entering sprocket indentations, when brake gear just in time corresponding teeth groove time, just directly enter teeth groove, mechanism directly can be in braking state; When braking gear and meeting with sprocket wheel crown, when namely there is apical tooth, braking gear cannot enter teeth groove, and arrestment mechanism enters state to be braked, but can not affect stop knob 5 and rotate to application position and upper braking lock afterwards operates.As long as no matter when Mobile shelves makes sprocket teeth rotate, braking gear automatically will snap in teeth groove under the effect of braking spring 17, and arrestment mechanism enters braking state automatically.Operator does not need to wait for or go to rotate handwheel 1 can enter braking state.Rotate knob and be arranged to " one " font, being non-brake state during level, is braking state time vertical, is easy to distinguish braking or non-brake two states.Upper braking lock mechanism: when when braking state, the braking lock core being contained in braking lock 4 on stop knob 5 is rotated counterclockwise with key, drive inner cam pin 3 to forward in the braking and locking groove of chuck 9, limit the rotation of stop knob, namely realize the upper braking lock of braking state.When needs Mobile shelves, opposite spin key both can brake off, and namely compact shelving can move freely.Stop knob has the circumferentially 120 ° of distributions of three claws, right through the breach of three on chuck 9 during installation, when knob half-twist is to application position, three claws are blocked by chuck 9, knob can not be pulled down on axle, eliminate the set screw of knob.If installation set screw, directly tighten if be contained in outside, then also can pull down in outside, then can pull down knob and make braking lock disabler, dangerous.Be contained in internal structure complexity, and install inconvenient.
As shown in Figure 2: driving chain tensioning mechanism: be made up of swing axis 22, wobble plate 21, Idle wheel 20, tension spring 23 etc.Swing axis 22 is fixed on driver plate 18, wobble plate 21 swings centered by swing axis 22, two Idle wheels 20 are contained in the other end of wobble plate 21, and one end of tension spring 23 is fixed on the other end on wobble plate 21 and is fixed on driver plate 18, and two immovable points are in the both sides up and down of swing axis 22.Under the pulling force effect of spring, wobble plate 21 can only rest on the low energy position of both sides, and can not be parked in middle high energy position.When chain 19 is on one side tightened up, the Idle wheel 20 of this side pushed down by the chain 19 of pilled-in selvedge, wobble plate 21 is forced to swing to direction, middle high energy position, when after crossing high energy position under tension spring 23 active force, rapid continuation swings to the low energy position of opposite side, until contact with the chain 19 of slack list and compress, thus realize the switching of slack list auto-tensioning.Vice versa.The Idle wheel of opposite side is then thrown off with chain 19 automatically, therefore only has an Idle wheel work another not work during tensioning, and this reduces transmission resistance on the one hand, and another aspect reduces mechanicalness noise.
