Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of erection device of Power Tong, comprise centralizing bracket 1, fixing seat 2, wiper block 3, pressing plate 4, screw 5, cushion pad 6, limited block 7, spring 8, stop screw 9, described erection device is fixed on Power Tong housing 11 or is fixed in Power Tong suspending rod 12, the forearm of centralizing bracket 1 and the back rest are provided with three chutes, fixing seat 2 is also three, and fixing seat 2 can move forward and backward position in chute, and fixing seat 2 is pressed abd fixed on centralizing bracket 1 by pressing plate 4, screw 5；Wiper block 3 is two, it is located in the fixing seat 2 of centralizing bracket 1 fore-arm, the central cross-section O-O that two wiper blocks 3 press Power Tong 10 jaw is symmetrical, limited block 7 is one, being located in the fixing seat 2 at centralizing bracket 1 back rest, the circular arc that two wiper blocks 3 and limited block 7 surround contains the tubing string 13 of institute's righting and concentric with the jaw central axis of Power Tong 10；Wiper block 3 and limited block 7 are inserted in the inner chamber of fixing seat 2 respectively, and spring 8 one end is against the interior intracavity of fixing seat 2, and one end is against the interior intracavity of wiper block 3 or spacing 7；Wiper block 3 and limited block 7 are provided with stopper slot, have a stop screw hole on fixing seat 2, stop screw 9 through the stop screw hole on fixing seat 2 to wiper block 3 or limited block 7 on stopper slot in.Guide ramp a and righting face b, guide ramp a and righting face b is had to be provided with one layer of cushion pad 6 on wiper block 3；Also being provided with one layer of cushion pad 6 on limited block 7, cushion pad 6 material one is to use oil resistant rubber, and two is to use nylon.Between cushion pad 6 and wiper block 3 and limited block 7, connected mode one is glued, and two is to be connected by screw.
When initially installing, can first make Power Tong 10 clamp tubing string 13, tubing string 13 and the jaw center centering of Power Tong 10, then wiper block 3 and limited block 7 be drawn close tubing string 13 respectively, appropriate gap can be stayed, then fix with pressing plate 4 and screw 5；Changing tubing string 13, when tubing string 13 size changes, more again according to pipe diameter size, unclamping pressing plate 4, readjust wiper block 3 and the position of limited block 7, to adapt to different tubing strings 13.In use, tubing string 13 enters in the middle of centralizing bracket 1, guide ramp a of wiper block 3 both sides guides tubing string 13 to enter binding clip center, when tubing string 13 rocks, spring 8 elastic force in wiper block 3 pushes away tubing string 13 to center, progressively reduce the amplitude rocked, until tubing string 13 enters binding clip center, centralizing bracket 1 below limited block 7 also ensure that tubing string 13 is in binding clip center.
As shown in Figure 4, when to little tubing string 13 operation, unclamp pressing plate 4, adjust wiper block 3 and the position of limited block 7, make wiper block 3 and limited block 7 fit tubing string 13, then fix with pressing plate 4 and screw 5, little tubing string 13 can be carried out righting.
