As shown in Figure 7, be separately installed with supporting plate 32 in the both sides of dental lamina seat 28, the two ends of each supporting plate 32 have groove, are equipped with disc spring 33 in this groove.As shown in Figure 8, joint detector 31 comprises detection oil cylinder 35, Linear displacement transducer 36 and the second proximity transducer 37, the piston rod detecting oil cylinder 35 is connected with Linear displacement transducer 36, and the end detecting oil cylinder 35 piston rod is provided with the second proximity transducer 37.
As shown in Figure 10 ~ 12, turnbuckle clamp 59 comprises: clamping cylinder 38, spinner arm 39, movable stand 40, guide strip 41, gripper shoe 48 and spinner assembly, wherein spinner assembly comprises: hydraulic motor 45, spinner frame 50 and spinner roller 43, the two ends of clamping cylinder 38 respectively symmetry are hinged with spinner arm 39, one end and the clamping cylinder 38 of each spinner arm 39 are hinged, and the other end is hinged with spinner frame 50.The below of movable stand 40 is provided with gripper shoe 48, and whole turnbuckle clamp 59 is arranged on the impact tong 22 of clamping clip by gripper shoe 48.Float and be positioned in gripper shoe 48 in the bottom of guide strip 41, the top of guide strip 41 between two backplates, and is passed by often organizing between roller.The transverse slat of guide strip 41 is provided with guide pin bushing 54, and this guide pin bushing 54 is parallel with the riser of guide strip 41, and guide pin bushing 54 top is inserted in the first sheath 55, and the lower end of guide rod 53 is inserted by guide pin bushing 54 top; Guide rod 53 is arranged with cluster spring 5, and this cluster spring 42 is connected on the inwall upper surface of the first sheath 55 and the transverse slat of guide strip 41 respectively.
Operating principle of the present utility model is:
First, drilling tool is contained in the groove on clamping clip 21 and impact tong 22.According to the distance that specification setting detection oil cylinder 35 piston rod of drilling tool stretches out.The revolution of telescopic arm drives pivoting support outer ring to engage by motor 3, because pivoting support outer ring is fixed in pedestal 1; Again because revolving support inner ring is fixed on revolving bed 2, the inner ring of pivoting support can relative to outer ring rotating, and then make revolving bed 2 rotate relative to pedestal 1 again; And inner arm 5, outer arm 6, hydraulic jack 7, telescopic displacement sensor 8, principal arm 9 and lifting gear turn round with revolving bed 2 jointly, and pass through the detection of encoder 4, realize the accurate location to well head direction.
Then, detect oil cylinder 15 and work, the second proximity transducer 37 of piston rod and end thereof is stretched out by clamping clip 21, and when reaching setpoint distance, Linear displacement transducer 36 sends signal, detects oil cylinder 35 and quits work.
Lifting gear works, and after accurately locating well head, hoist cylinder 10 drives inner sleeve 11 vertically to move downward, and is elevated displacement transducer and is used for detecting vertical displacement, thus realizes the accurate location in short transverse.Clamping clip 21 and impact tong 22 move down with lifting gear, until move to the second proximity transducer 37 detected on oil cylinder 35 piston rod tool joint place to be detected, lifting gear moves down setpoint distance again, quits work.Clamping cylinder 38 works, and makes the relative movement of two spinner framves 50, until after contacting with drilling tool, clamping cylinder 38 quits work.Then hydraulic motor 45 works, and drives driving gear 52 to drive the driven gear 51 of its both sides to rotate, and then two spinner rollers 43 are rotated, with the friction between drilling tool, drilling tool is connected by spinner roller 43.After the 3rd pressure sensor 44 detects the pressure reaching setting moment of torsion, hydraulic motor 45 receives signal and quits work.Two spinner framves 50 are opened by clamping cylinder 38 reverse operation again.
After turnbuckle clamp quits work, punch oil cylinder 23 works, and make clamping clip 21 clamp lower drilling tool, impact tong 22 rotates relative to clamping clip 21, top drilling tool and lower drilling tool is screwed and links into an integrated entity.Rotate in the process of backhaul once at impact tong 22, the first proximity transducer 30 on clamping clip 21 sends signal after the flat board on impact tong 22 being detected, represent that impact tong 22 gets back to initial position, the piston rod of punch oil cylinder 23 stops retracting, start oppositely to stretch out, screw, until drilling tool has connected next time.
The above-mentioned operating process for drilling tool connection, as dismantled drilling tool, is then first relatively rotated by clamping clip 21 and impact tong 22, makes to unscrew between drilling tool, and then utilizes turnbuckle clamp 59 that top drilling tool is rotated, until taken apart by upper and lower two drilling tools.
