Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the invention will be further described, but should not limit the scope of the invention with this.
Composition graphs 1 to Fig. 5, the pincer set deflection device for iron roughneck 1 of the present embodiment comprises: connecting axle 11, support 12, spring 13, roller body 14, location-plate 15, horizontal axle sleeve 16, longitudinal axis 17, longitudinal axle sleeve 18, circumference scotch 19, axial stop 110.
Wherein, pincer set deflection device for iron roughneck 1 by connecting axle 11 and longitudinal axis 17 hinged with pincers group 3.Longitudinal axle sleeve 18 is connected on telescopic arm link 2, in the present embodiment, longitudinal axle sleeve 18 by Flange joint on telescopic arm link 2.
Connecting axle 11 rotates in horizontal axle sleeve 16 (in other words, horizontal axle sleeve 16 is arranged on connecting axle 11), and longitudinal axis 17 and horizontal axle sleeve 16 consolidation, form cross hinge; The two ends of longitudinal axis 17 by the Flange joint on longitudinal axle sleeve 18 on telescopic arm link 2.For being rotatably connected between the two ends of longitudinal axis 17 and longitudinal axle sleeve 18.
Longitudinal axis 17 and horizontal axle sleeve 16 consolidation form cross hinge, and pincers group 3 can swung around connecting axle 11 and longitudinal axis 17 with pincer set deflection device for iron roughneck 1 in horizontal and vertical both direction.Time not parallel between the vertical line and the vertical line of pipeline of pincers group 3, pincers group 3 is in the process of clamping pipe fitting, because pipe fitting is rigid state, thus pincers group 3 can produce beat along with pipe fitting, is overlapped by the vertical line of pincers group 3 with the vertical line of pipe fitting.
Composition graphs 5 to Fig. 7, the two ends of longitudinal axis 17 are fixed with circumference scotch 19, and longitudinal axle sleeve 18 is arranged on the two ends of longitudinal axis 17, and the flange of longitudinal axle sleeve 18 is provided with arc groove, circumference scotch 19 is limited in this arc groove, thus the rotational angle of restriction longitudinal axis 17.The two ends of longitudinal axis 18 are also distributed with axial stop 110, to limit the axial float of longitudinal axis 17.
Fig. 9 to Figure 11 shows the structure of the circumference scotch of the present embodiment, in it, square hole can be enclosed within the square shaft shoulder of longitudinal axis, this circumference scotch is rotated with longitudinal axis, and the projection at circumference scotch cylindrical place can swing in the arc groove of the flange of longitudinal axle sleeve.
With reference to figure 8, the connecting axle 11 of the present embodiment is also consolidated with location-plate 15, this location-plate 15 rotates with connecting axle 11, and the inner side of location-plate 15 has deep-slotted chip breaker, and the shape of this deep-slotted chip breaker preferably has the acceleration characteristic of cam curve.The roller of roller body 14 upper end is fastened in the deep-slotted chip breaker inside location-plate 15, and lower end pressing spring 13, spring 13 is arranged in support 12.
In conjunction with Figure 12 to Fig. 1 to Fig. 8, when pincers group 3 drives connecting axle 11 to rotate in horizontal axle sleeve 16, location-plate 15 also rotates thereupon, and the deep-slotted chip breaker inside location-plate 15 orders about roller body 14 and moves downward, Compress Spring 13; After pincers group 3 unclamps pipe fitting, the external force of deflection device 1 is eliminated, discharged by the spring 13 compressed, raise roller body 14 and move upward, promote location-plate 15, because the arc curve inside location-plate 15 has acceleration characteristic, thus the roller of roller body 14 can be got back in the deep-slotted chip breaker inside location-plate 15 fast, thus promotes location-plate 15 and rotate, and the rotating band of location-plate 15 axle 11 that is dynamically connected rotates, then drive pincers group 3 to rotate, pincers group 3 is resetted.
In conjunction with Figure 13, Figure 14 and Fig. 1 to Fig. 8, wherein Figure 13 is that pincers group 3 works the front or position of pincer set deflection device for iron roughneck 1 after resetting, and Figure 14 is that pincers group 3 swings the position of rear pincer set deflection device for iron roughneck 1 around longitudinal axis 17.Pincers group 3 is around longitudinal axis 17 in longitudinal axle sleeve 18 during passive rotation, and circumference scotch 19 rotates with longitudinal axis 17, the rotation of the arc groove restriction circumference scotch 19 of the flange of longitudinal axle sleeve 18, and then the rotational angle of restriction longitudinal axis 17.After pincers group 3 unclamps pipe fitting, pincers group 3 can rely on deadweight to rotate, and is returned to reset position.
Although the present invention with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible variation and amendment, the scope that therefore protection scope of the present invention should define with the claims in the present invention is as the criterion.
