Refer to Fig. 1 to Fig. 3, two pipe boring grabs 100 of an embodiment of the present utility model, for the boring that superposes after 200 stacks of two pipes are clamped, this pair pipe boring grab 100 comprises fixedly anchor ear 110, movable anchor ear 120 and driving handle 130.
Fixedly anchor ear 110 comprises substrate 111, the first side plate 113 and the second side plate 115, the first side plate 113 and the second side plate 115 are vertically fixed on the same surface of substrate 111, and the first side plate 113 and the second side plate 115 are spaced, on the surface at substrate 111, to form clamping region.On the first side plate 113 side relative with the second side plate 115, be formed with the first clamping slot 113a of arc, the first clamping slot 113a matches with the outer surface of one of them pipe 200.
Specifically in illustrated embodiment, the first clamping slot 113a is circular arc, and the bending radius of the cell wall of the first clamping slot 113a is identical with the bending radius of the outer surface of one of them pipe 200.Because the bending radius of the cell wall of the first clamping slot 113a is identical with the bending radius of the outer surface of one of them pipe 200, make pipe 200 can be close to the cell wall setting of the first clamping slot 113a, thereby comparatively stably clamp pipe 200, and increase the cell wall contact area of pipe 200 and the first clamping slot 113a, avoid too firmly crushing pipe 200.
In other embodiments, the first clamping slot 113a is ellipse arc, makes the first clamping slot 113a can be suitable for the pipe 200 of different size.
Specifically in illustrated embodiment, the second clamping slot 121 is circular arc, and the bending radius of the cell wall of the second clamping slot 121 is identical with the bending radius of the outer surface of another one pipe 200.Because the bending radius of the cell wall of the second clamping slot 121 is identical with the bending radius of the outer surface of another one pipe 200, make pipe 200 can be close to the cell wall setting of the second clamping slot 121, thereby comparatively stably clamp pipe 200, and increase the cell wall contact area of pipe 200 and the second clamping slot 121, avoid too firmly crushing pipe 200.
In other embodiments, the second clamping slot 121 is ellipse arc, makes the first clamping slot 113a can be suitable for the pipe 200 of different size.
Further, be formed with blind hole (figure is mark) on movable anchor ear 120 and side that driving shaft 131 is connected, the free end of driving shaft 131 inserts in blind hole.
Further; two pipe boring grabs 100 also comprise the neonychium 140 of two arcs; two neonychiums 140 are arranged on respectively in the first clamping slot 113a and the second clamping slot 121, and the shape of the shape of two neonychiums 140 and the first clamping slot 113a and the second clamping slot 121 is suitable.By neonychium 140, clamp pipe 200, can avoid crushing pipe 200.
A progressive ground, neonychium 140 is rubber blanket or foam-rubber cushion.And; neonychium 140 can be arranged in the first clamping slot 113a and the second clamping slot 121 in different ways; for example; between the cell wall of neonychium 140 and the first clamping slot 113a and the second clamping slot 121, be provided with double faced adhesive tape or glue, neonychium 140 is sticked on the cell wall of the first clamping slot 113a and the second clamping slot 121.
A progressive ground, the central angle of the first clamping slot 113a and the second clamping slot 121 correspondences all are less than or equal to 180 degree.When the central angle of the first clamping slot 113a and the second clamping slot 121 correspondences all is less than 180 while spending, even the first clamping slot 113a and the second clamping slot 121 are circular arc, it is also applicable to the pipe 200 of different sizes.When the central angle of the first clamping slot 113a and the second clamping slot 121 correspondences is equal to 180 degree, make the contact area maximum of pipe 200 and the first clamping slot 113a and the second clamping slot 121.
Above-mentioned pair of pipe boring grab 100 adopts fixedly one of them pipe 200 of cell wall butt of the first clamping slot 113a of the first side plate 113 of anchor ear 110, the cell wall butt another one pipe 200 of the second clamping slot 121 of employing activity anchor ear 120, and the shape of the first clamping slot 113a and the second clamping slot 121 and the shape of pipe 200 are substantially adaptive, thereby stably two pipes 200 are clamped together side by side, hole again, guarantee the uniformity of position, hole, thereby improve the accuracy of boring.In addition, by driving handle 130 promotion activity anchor ears 120, to change movable anchor ear 120 and the fixing spacing between the first side plate 113 of anchor ear 110, to be applicable to the pipe 200 without size.
For example, when the framework that adopts above-mentioned pair of pipe boring grab 100 clamping generators and reinforced frame, movable anchor ear 120 is held two pipes 200 tightly, then holes, and guarantees the uniformity of position, hole.Then utilize spiral principle, compressed by driving handle 130 promotion activity anchor ears 120, cause movable anchor ear 120 and fixedly the size between the first side plate 113 of anchor ear 110 dwindle, hold two pipes 200 tightly.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
