In figure, 1. locking pin seat, 2. stop pin, 3. tooth bar, 4. gear, 5. locating dowel pin, 6. ear seat, 7. axle, 8. rotary handle, 9. bearing, 10. proximity switch, 20. turntables, 21. pivoting supports, 22. rotary reducers, 23. pedestals, 24. holes.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, slewing lock of the present utility model is for locking the turntable 20 of ocean loop wheel machine, this turntable 20 is bolted with the outer ring of pivoting support 21, pivoting support 21 inner ring is internal tooth arrangement, turntable 20 is provided with rotary reducer 22, the transmission gear of rotary reducer 22 engages with pivoting support 21 inner ring and realizes driving turntable 20 to rotate; Axially have hole 24 at pedestal 23, directly over hole 24 corresponding locked position turntable 20 in have mounting hole.
With reference to Fig. 2, Fig. 3, slewing lock structure is, include locking pin seat 1, locking pin seat 1 is welded in the mounting hole of turntable 20, in locking pin seat 1, slip cap is equipped with stop pin 2, circumferentially axially tooth bar 3 is welded with at stop pin 2, tooth bar 3 and gear 4 are connected by meshing transmission, gear 4 is fixedly connected with rotary handle 8, stop pin 2 realizes up-and-down movement by tooth bar 3 and the gearing of gear 4, gear 4 is arranged on ear seat 6 by axle 7, and ear seat 6 is fixed on turntable 20 lower surface, and being provided with between axle 7 and ear seat 6 can the bearing 9 of self-lubricating;
In addition, also comprise locating dowel pin 5 and proximity switch 10, in locking pin seat 1 and stop pin 2, have corresponding pin-and-hole along horizontal radial, in this pin-and-hole, insert locating dowel pin 5 when stop pin 2 is lifted to a high position, locating dowel pin 5 is used for stoping stop pin 2 to fall in the unlocked state; Be installed with proximity switch 10 at pedestal 23 following table face 24 correspondence position, proximity switch 10 is used for detecting stop pin 2, and whether patchhole 24 lowermost position is put, and judges that slewing lock is in locking or released state with this.
Slewing lock specific operation process of the present utility model is as follows:
When ocean loop wheel machine quits work, first locating dowel pin 5 is extracted, stop pin 2 just can slide in locking pin seat 1, then rotary handle 8 is upwards pulled, driven gear 4 is around axle 7 left-hand revolution, gear 4 engages with tooth bar 3, drives tooth bar 3 to move down, the stop pin 2 welded with tooth bar 3 slide downward in locking pin seat 1.When in stop pin 2 completely patchhole 24, turntable 20 is mechanically locked, and the lower surface of stop pin 2 arrives the induction range of proximity switch 10, and proximity switch 10 is triggered, and provides signal to loop wheel machine control system, and the action of restriction loop wheel machine, prevents maloperation, see Fig. 2.
Otherwise when ocean loop wheel machine dead work, pull rotary handle 8 downwards, gear 4 rotates clockwise, and gear 4 drives tooth bar 3 to move up, drive stop pin 2 upward sliding in locking pin seat 1.When rotary handle 8 forwards the end to, when stop pin 2 is extracted completely from hole 24, inserted by locating dowel pin 5 in the hole of stop pin 2 upper end, turntable 20 unlocks, and freely can turn round, see Fig. 3.
