In figure: 1, rotating shaft, 2, Spur Internal Gears of Clutch, 3, external clutch gear, 4, convex parts, 5, the shift fork arm, 6, connecting rod III, 7, bearing I, 8, connecting rod II, 9, ram, 10, connecting rod I, 11, bearing II, 12, frame, 13, fixing pin, 14, groove I, 15, groove II.
Embodiment
In Fig. 1, Fig. 2, clutch lock-bit device mainly is comprised of external gear 2,3 in frame 12, ram 9, shift fork arm 5 and clutch, ram 9 one ends are fixedly connected on frame 12, the other end is connected with the shift fork arm 5 that plays the connecting rod effect, and the convex parts 4 on shift fork arm 5 is arranged in the groove II 15 of external clutch gear 3.
When ram 9 drives, it drives shift fork arm 5 and realizes external gear 2 in clutch, 3 Engage and disengage, after the clutch combination, because driving force exists always, convex parts 4 exists with the pressure of Spur Internal Gears of Clutch 2 surface of contact always, wearing and tearing, the especially wearing and tearing of convex parts 4 of convex parts 4 with Spur Internal Gears of Clutch 2 surface of contact have been accelerated.
If shed ram 9 driving forces, external gear 2 in clutch, 3 situations about breaking away from suddenly can occur in clutch often so, make winch out of control, have brought very large danger for the testing well operation.
In Fig. 3, Fig. 4, clutch lock-bit device, mainly consisted of by frame 12, ram 9, rotating shaft 1 and the fourbar linkage that formed by connecting rod I 10, connecting rod II 8, connecting rod III 6 and shift fork arm 5, ram 9 one ends are articulated and connected on bearing I 7 by bearing pin, bearing I 7 is welded to connect on frame 12, ram 9 the other ends are connected with connecting rod I 10 middle parts by bearing pin, connecting rod I 10 is 2, one end and bearing II 11 are articulated and connected by bearing pin, and the other end is articulated and connected by bearing pin and connecting rod II 8.
As connecting rod I 10 when connecting rod II 8 is on same straight line, near ram 9 and with connecting rod II 8 that connecting rod I 10 overlaps on be provided with fixing pin 13, with be provided with groove I 14 on the connecting rod I 10 of fixing pin 13 corresponding positions, fixing pin 13 is stuck in 14 li of this groove I, has realized connecting rod I 10, connecting rod II 8 self-locking to ram 9 direction motions; As another kind of embodiment, as connecting rod I 10 when connecting rod II 8 is on same straight line, near ram 9 and with connecting rod I 10 that connecting rod II 8 overlaps on be provided with fixing pin 13, with be provided with groove I 14 on the connecting rod II 8 of fixing pin 13 corresponding positions, fixing pin 13 is stuck in 14 li of this groove I, has realized connecting rod I 10, connecting rod II 8 self-locking to ram 9 direction motions.
Connecting rod II 8 and connecting rod III 6 are articulated and connected by bearing pin, rotating shaft 1 is fixedly connected on frame 12, connecting rod III 6 and shift fork arm 5 all are welded to connect in rotating shaft 1, be provided with convex parts 4 on shift fork arm 5, this convex parts 4 is arranged in the groove II 15 of Spur Internal Gears of Clutch 2, during work, drive convex parts 4 by fourbar linkage and realize external gear 2 in clutch, 3 Engage and disengage, thereby reach the Engage and disengage of clutch.Described ram 9 can be pneumatic cylinder or oil hydraulic cylinder.
When clutch need to enter jointing state, ram 9 shrinks, drivening rod I 10 rotates to the direction of frame 12 centered by bearing II 11, rotate centered by rotating shaft 1 through connecting rod II 8 drivening rod III 6, because shift fork arm 5, connecting rod III 6 all are welded in rotating shaft 1, engage with external clutch gear 3 therefore drive Spur Internal Gears of Clutchs 2 by convex parts 4, thereby reach the jointing state of clutch.Due to the existence of fixing pin 13 and ram 9 contractile forces, connecting rod I 10 and connecting rod II 8 have realized self-locking, have solved the wearing and tearing that reduced convex parts 4 on shift fork arm 5, have avoided external gear 2 in clutch, 3 phenomenons that break away from suddenly, and be simple in structure, easy to make.
When clutch need to enter separated state, ram 9 stretched out, the power destruction connecting rod I 10 by ram 9 and the self-locking state of connecting rod II 8, and then reach that in clutch, external gear 2,3 is in separated state.
