Going upward on the upside of back-up tong main body 3 after preformed hole until arc shoe plate 4c, whole back-up tong main body moves upwardly off drilling rod working region along with liquid presses piston pole 4b；
The course of work of shackle is similar, and simply main shaft direction of rotation is different, repeats no more.
Advantages of the present invention is as follows:
1, envelope angle is big, it is possible to added drilling rod carries out certain school circle function, has certain applicability to the drilling rod with deformation, extend the service life of drilling rod.Owing to six prism dissimilar tooth forms on the right side of lever are the pipe diameter determing for different size, each prism is to the envelope angle of drilling rod more than 80 degree, and the compound constant envelope angle of left end is more than 100 degree, and total envelope angle is not less than 260 degree；
2, flexible and rigid composite clamps, and clamping performance is good.The design of lever 6c and 6d part, makes restraint strap 6c first contact drilling rod, along with the increase enveloping surface of thrust is also increasing, it is possible to ensure that three part block teeth reach maximum clamping force simultaneously.Existing flexible constraint has again rigid constraint, and clamping force is more uniform, and clamping stability is good.Compared with traditional rigid grasp, the clamping force that the clamping effect reaching identical needs is less.Opposing twisting property is good, extends the service life of drilling rod；
3, simple in construction, low cost of manufacture.Only one of which hydraulic cylinder is achieved that the action on the descending of back-up tong and two different directions of clamping, effectively avoids the redundancy of structure.Overall structure is simple, and part parts are few.Owing to not having the hydraulic test of level, the weight of this back-up tong is substantially reduced, it is to avoid drilling rod eccentric wear phenomenon.Also simplify integrated hydraulic system simultaneously, reduce manufacturing cost.The fault rate of back-up tong reduces, and reliability is greatly improved；
4, can automatic centering.Roomy guide rail ensure that back-up tong main body is horizontal.Six prism block teeth 8 parts (as shown in Figure 5) process different annular mouth for six kinds of different calibers, it is ensured that for the well adapting to property of drilling rod of different tube diameters, keep face contact to greatest extent.And the position of six prisms and angle ensure that drilling rod steps up afterwards and top protection short circuit is on a center line, it is achieved that the automatic centering of drilling rod；
5, abrasion is less, and not damaged is in drilling rod.The coefficient of friction that the restraint strap 6c in left side and the coefficient of friction of drilling rod are far longer than between block teeth and drilling rod, compared with traditional rigid grasp, the clamping force that the clamping effect reaching identical needs is little, protects drill pipe coupling, extends drilling life of drill pipe；
6, regular maintenance is convenient.After end-of-job, back-up tong vertical direction activity space is big, provides bigger working space for changing block teeth, protection pipe nipple or IBOP.Only need to remove the most replaceable whole back-up tong of roller.Back-up tong vertical direction activity space can exempt from greatly to damage drilling rod；
7, the held tight to different calibers can be realized flexibly.Clamping part on the left of the design has flexible restraint ties, it is possible to the spacing of two block teeth 6ds is adjusted flexibly for different tube diameters, i.e. automatically adapts to different calibers.By six prism block teeth 8 on the right side of rotating, it is possible to produce specific aim clamping with different tube diameters；
8, vertical spring has damping and the function fluctuated.On drilling rod during shackle, due to the elastic reaction of spring 5, back-up tong is on the premise of the drilling rod of clamping, additionally it is possible to provide a vertical floating space flexibly, makes up the drilling rod that pitch is brought and the deviation pushing up the vertical direction driving main shaft；
9, hydraulic cylinder life is longer, and winter is not susceptible to the phenomenon that freezes.The design only has a vertical hydraulic cylinder, the better tightness of hydraulic oil.On back-up tong in the shackle course of work, inevitably having drilling fluid, even landwaste and trickle down in back-up tong main body, the back-up tong with horizontal hydraulic cylinder easily produces hydraulic cylinder serious wear, and summer operation easy leakage of oil is easily freezed when winter works；
10, the anti-torsion active force that back-up tong guide rail provides is big, and the width of back-up tong is 2 ~ 3 times of drill pipe diameter, has roomy back-up tong guide rail simultaneously, has preferable twisting action performance.
