According to technical scheme provided by the invention, a kind of upper shed reinforcement self-centering clamping device, comprise and grip seat, sliding seat, telescopic oil cylinder, gripper jaw and switching mechanism, it is characterized in that: grip a top and be provided with two symmetrical grip slippers, in each grip slipper, be provided with a gripper jaw.Gripper jaw is provided with the draw-in groove of up/down perforation, and the pinned connection gripper jaw of side through draw-in groove, and is passed through in sliding seat upper end.Grip a upper end and be provided with switching mechanism.Telescopic oil cylinder upper end connects grip slipper, and lower end connects sliding seat.
Further, sliding seat connects the stopper slot that bearing pin place is provided with long waist shaped, the angular range of stopper slot center line and horizontal plane is 6 ~ 45 °.
Further, gripper jaw one end is V-arrangement end face, two sides of V-arrangement end face is respectively equipped with a slips holddown groove, is connected by screw a slips in each slips holddown groove.
Further, switching mechanism comprises the returning face plate being rotatably connected on and gripping on seat, and both sides, returning face plate front end are rotationally connected latch, connect extension spring between latch and returning face plate; Latch is provided with latch buckle, grip seat be provided be clasped with latch bayonet socket grip a bayonet socket.
Further, returning face plate front end is provided with fastening plate, is provided with fastening groove in fastening plate.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, adopts upper opening type structure, and drilling rod is convenient to be taken out from top; Adopt inclined-plane multiplication mechanism, considerably increase chucking power when same oil cylinder power; Adopt bibeveled automatic centering mechanism, ensure self-centering clamping from frame for movement or unclamp; Reliability is high, makes rig in the dismounting drilling rod course of work, ensures the centering clamping work of drilling rod.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises and grips seat 1, sliding seat 2, telescopic oil cylinder 3, gripper jaw 4 and switching mechanism 5, grips seat 1 top and is provided with two symmetrical grip slippers 6, be provided with a gripper jaw 4 in each grip slipper 6.Gripper jaw 4 is provided with the draw-in groove 7 of up/down perforation.Sliding seat 2 upper end through draw-in groove 7, and connects gripper jaw 4 by the bearing pin 8 of side.
As shown in Figure 3, described sliding seat 2 connects the stopper slot 9 that bearing pin 8 place is provided with long waist shaped, the angular range of stopper slot 9 center line and horizontal plane is 6 ~ 45 °.
As shown in Figure 4, described gripper jaw 4 one end is V-arrangement end face, two sides of V-arrangement end face is respectively equipped with a slips holddown groove 10, is connected by screw a slips 11 in each slips holddown groove 10.
As shown in Figure 1, grip seat 1 upper end and be provided with switching mechanism 5, switching mechanism 5 comprises the returning face plate 12 being rotatably connected on and gripping on seat 1, and both sides, returning face plate 12 front end are rotationally connected latch 14, connect extension spring 13 between latch 14 and returning face plate 12.Latch 14 is provided with latch buckle 15, grip seat 1 be provided be clasped with latch bayonet socket 15 grip a bayonet socket 16.After rotation returning face plate 12 puts in place, owing to pulling back in latch 14 upper end by extension spring 13 tightening force, stressed the entering of latch buckle 15 grips locking in a bayonet socket 16, prevents the workpiece blocked in two gripper jaws 4 from upper disengaging.
Returning face plate 12 front end is provided with fastening plate 17, is provided with fastening groove 18 in fastening plate 17.When two gripper jaws 4 block workpiece, sliding seat 2 upper end enters in fastening groove 18 stuck.
Telescopic oil cylinder 3 upper end connects grip slipper 6, and lower end connects sliding seat 2.
Operating principle of the present invention is: when the moved downward of oil cylinder at pressure oil, drives sliding seat 2 to move downward.Sliding seat 2 be provided be obliquely installed stopper slot 9 (can according to required clamping distance of stretch out and draw back and once power size design the angle of inclination of stopper slot 9), sliding seat 2 moves downward, the pitch smaller of the bearing pin 8 of gripper jaw 4 is connected in stopper slot 9, cause gripper jaw 4 drilling rod close to each other in two grip slippers 6, thus clamp drilling rod mutually.Equally, when oil cylinder moves upward under the effect of pressure oil, cause the gripper jaw 4 in two grip slippers 6 to leave drilling rod simultaneously, thus unclamp drilling rod.Grip the switching mechanism 5 of seat 1 upper end setting for locking frozen drill pipe.
Structure of the present invention is simple, compact, reasonable, adopts upper opening type structure, and drilling rod is convenient to be taken out from top; Adopt inclined-plane multiplication mechanism, considerably increase chucking power when same oil cylinder power; Adopt bibeveled automatic centering mechanism, ensure self-centering clamping from frame for movement or unclamp; Reliability is high, makes rig in the dismounting drilling rod course of work, ensures the centering clamping work of drilling rod.
