Described operating mechanism also comprises a fixture, and described fixture is used for main jaw mechanism and one of them person of back-up tong mechanism are fixed in framework.
Offer two fixing holes on the described framework, respectively offer one and two fixing holes corresponding positioning hole respectively in described main jaw mechanism and the back-up tong mechanism, when being inserted in the described locating hole after described fixture passes described fixing hole, described main jaw mechanism is fixed on the described framework; When being inserted in the described locating hole after described fixture passes described fixing hole, described back-up tong mechanism is fixed on the described framework.
Described detent mechanism comprises first guide rail, rotation fluid cylinder and is fixed in supporting seat on first guide rail rotationally, and described supporting base is used to support described operating mechanism, and described rotation fluid cylinder one end connects supporting seat, and the other end is fixed on first guide rail slidably.
Described detent mechanism comprises first guide rail, second guide rail, support arm, rotation fluid cylinder and supporting seat, described second guide rail is perpendicular to the first guide rail setting, described support arm one end is fixed on second guide rail, described supporting base is arranged on second guide rail slidably, be used to support described operating mechanism, described rotation fluid cylinder one end connects described support arm, and the other end is arranged on described first guide rail slidably.
Selectively on the fixed frame, therefore, above-mentioned Power Tong not only can be finished the last shackle between the drilling rod, can also finish the last shackle work between drilling rod and the drill bit for the main jaw mechanism of above-mentioned Power Tong and one of them person of back-up tong mechanism.
Description of drawings
Fig. 1 is the stereogram of a preferred embodiment Power Tong.
Fig. 2 is the stereogram of the operating mechanism of Fig. 1 medium power pincers.
Fig. 3 is the exploded view of operating mechanism among Fig. 2.
The specific embodiment
As shown in Figure 1, be the stereogram of a better embodiment Power Tong 100.Power Tong 100 comprises operating mechanism 10 and is used to adjust the detent mechanism 20 of the operating position of operating mechanism 10.
As shown in Figures 2 and 3, operating mechanism 10 comprises framework 11, main jaw mechanism 13, back-up tong mechanism 15, goes up a hydraulic break out cylinder 17 and a fixture 19.Main jaw mechanism 13, back-up tong mechanism 15 and last hydraulic break out cylinder 17 are arranged in the framework 11.
Framework 11 is fixed on the detent mechanism 20.Framework 11 comprises top board 111 and the base plate 113 relative with top board 111.Offer fixing hole 115 on the top board 111, offer fixing hole 117 on the base plate 113.Main jaw mechanism 13, back-up tong mechanism 15 and last hydraulic break out cylinder 17 are arranged between top board 111 and the base plate 113.
Last hydraulic break out cylinder 17 1 ends are fixed on the main jaw mechanism 13, and the other end is fixed in the back-up tong mechanism 15, so that can relatively rotate between winner's jaw mechanism 13 and the back-up tong mechanism 15.
One end of support arm 25 is fixed on second guide rail 22.One end of rotation fluid cylinder 29 is fixed on the other end of support arm 25, and the other end is arranged on first guide rail 21 slidably.When 29 work of rotation fluid cylinder, drive second guide rail 22 by support arm 25 and rotate with respect to first guide rail 21, rotate thereby drive operating mechanism 10, so that operating mechanism 10 can arrive suitable position, be convenient to work.
When the needs working power clamps shackle two drilling rods on 100 when (figure does not show), at first, be inserted in the locating hole 151 after fixture 19 passed fixing hole 117, make back-up tong mechanism 15 be fixed on the framework 11, at this moment, main jaw mechanism 13 can rotate with respect to back-up tong mechanism 15 and framework 11 under last hydraulic break out cylinder 17 must act on; Then, the flexible height of adjusting operating mechanism 10 by lifting fluid cylinder 27, by the flexible adjustment operating mechanism 10 of rotation fluid cylinder 29 and the position between the drilling rod, when operating mechanism 10 is positioned at suitable position, make main jaw mechanism 13 hold drilling rod tightly, back-up tong mechanism 15 holds down drilling rod tightly, hydraulic break out cylinder 17 in the startup, drive main jaw mechanism 13 and rotate, thereby make that going up drilling rod rotates with respect to following drilling rod, thereby realize the last shackle of two drilling rods with respect to back-up tong mechanism 15.
When needs working power pincers 100 with drill bit and drilling rod on during shackle, at first, be inserted in the locating hole 131 after fixture 19 passed fixing hole 115, so that main jaw mechanism 13 is fixed on the framework 11, make back-up tong mechanism 15 under the effect of last hydraulic break out cylinder 17, can rotate with respect to main jaw mechanism 13 and framework 11; Then, the flexible height of adjusting operating mechanism 10 by lifting fluid cylinder 27, by the flexible adjustment operating mechanism 10 of rotation fluid cylinder 29 and the position between the drilling rod, when operating mechanism 10 was positioned at suitable position, main pincers 13 were held drilling rod tightly, and back-up tong mechanism 15 holds drill bit tightly, hydraulic break out cylinder 17 in the startup, drive back-up tong mechanism 15 and rotate, thereby make drill bit rotate, thereby realize the last shackle of drilling rod and drill bit with respect to drilling rod with respect to main jaw mechanism 13.
