Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 to Fig. 3, this kind of oil drill rocker joint hoop detector, its agent structure is made up of middle hold-fast body, upper detection mechanism and bottom testing agency three parts, it is unique in that: described upper detection mechanism is identical with the structure of bottom testing agency, and described middle hold-fast body includes chela 1, lower chela 12, hydraulic cylinder 7, grease fitting 9, linking arm 11, connects bearing pin 18 and hydraulic joint 17; Described upper detection mechanism includes contact head 2, expansion link 3, upper cover plate 4, rear end cap 6, installs leg 5, groove box 8, compression spring 15 and detection sensor 16.
Wherein, being connected on slide block 23 with connecting the upper chela 1 of bearing pin 18, lower chela 12 and linking arm 11, slide block 23 is connected with the piston rod 25 in hydraulic cylinder 7; Described upper detection mechanism and bottom testing agency are separately mounted to the upper and lower both sides of described middle hold-fast body; Contact head 2 and expansion link 3 use bolt to carry out releasable connection, lead 22 is fixed on the centre of expansion link 3 by screw 24, compression spring 15 is inserted on the lead 22 being positioned in the middle of expansion link 3, it is integrally attached in the chute in the middle of groove box 8, compression spring 15 is in close contact with the detection sensor 16 on rear end cap 6, the end of expansion link 3 is welded with square wing plate, to prevent described contact head from rotating. Upper chela 1 and lower chela 12 can be replaced using according to different calibers; Whole device is connected with other equipment by installing leg 5.
During use, whole detection action first passes through Hydraulic Cylinder chela and holds tubing string tightly, transfer or lift up at drilling rod in process, contacted with tubing string respectively by upper and lower two contact heads, drilling rod joint hoop location is judged by the unlike signal obtained by upper and lower two sensors detection, completes the position detection to joint hoop.
Below in conjunction with accompanying drawing, put under description drilling rod and snap through journey:
Fig. 4,5,6 are that three operating diagram snapping through journey put by drilling rod joint hoop detector under drilling rod respectively.First detector being arranged on during work needs on the upper proper height position detaining operation, in the present invention designs, the hydraulic oil first passing through hydraulic cylinder 7 promotes piston rod 25 protruding, and piston rod 25 promotes slide block 23 to drive upper chela 1 and lower chela 12 to hold drilling rod 21 tightly by bearing pin 18, linking arm 11. Simultaneously because the effect of spring 15 makes contact head 2 and contact head 14 and the close contact of drilling rod 21 outer wall. When drilling rod is transferred, the starting stage all contacts with tube wall with contact head 14 due to contact head 2, and contact head does not move, and upper detection sensor 16 is consistent with the output signal in lower detection sensor 19; When joint hoop 20 arrival, first contact head 2 contacts joint hoop 20, owing to joint hoop place drill pipe diameter becomes big, along with drilling rod moves down, contact head 2 and expansion link 3 are forced to be moved rearwards by, spring 15 is forced compression, detection sensor 16 power under spring action increases, and now produces a signal output, and the big hook joint of lowering drill pipes makes drilling rod slow down after receiving this signal mobile, contact head 14 is but without touching joint hoop, and the output signal of detection sensor 19 does not change; Drilling rod continues to move down, and when contact head 14 touches joint hoop, contact head 14 and expansion link 13 are forced to be moved rearwards by, and spring is compressed, and now detection sensor 19 has signal to export, a signal data of getting back; This signal represents that joint hoop has arrived at the job position of needs, and drilling rod stops mobile, is now carried out upper button operation by workman or upper button plant equipment.
In conjunction with accompanying drawing 7 to accompanying drawing 9, describe drilling rod and lift up shackle process:
Fig. 7,8,9 are three operating diagram that drilling rod joint hoop detector lifts up shackle process at drilling rod respectively. First detector is arranged on the proper height position needing shackle operation during work, in the present invention designs, the hydraulic oil first passing through hydraulic cylinder 7 promotes piston rod 25 protruding, and piston rod 25 promotes slide block 23 to drive upper chela 1 and lower chela 12 to hold drilling rod 21 tightly by bearing pin 18, linking arm 11. Simultaneously because the effect of spring 15 makes contact head 2 and contact head 14 and the close contact of drilling rod 21 outer wall. When drilling rod lifts up, the starting stage all contacts with tube wall with contact head 14 due to contact head 2, and contact head does not move, and detection sensor 16 is consistent with the output signal in detection sensor 19; When joint hoop 20 arrival, first contact head 14 contacts joint hoop 20, owing to joint hoop place drill pipe diameter becomes big, along with drilling rod moves up, contact head 14 and expansion link 13 are forced to be moved rearwards by, spring 15 is forced compression, detection sensor 19 power under spring action increases, and now produces a signal output, and it is mobile that the big hook joint of lift drilling rod makes drilling rod slow down after receiving this signal, contact head 2 is but without touching joint hoop, and the output signal of piezoelectric transducer 16 does not change; Drilling rod continues to move up, and when contact head 2 touches joint hoop 20, contact head 2 and expansion link 3 are forced to be moved rearwards by, and spring 15 is compressed, and now detection sensor 16 has signal to export, a signal data of getting back; This signal represents that joint hoop has arrived at the job position of needs, and drilling rod stops mobile, is now carried out shackle operation by workman or shackle plant equipment.
