The purpose of this utility model can realize by following technical proposal: a kind of pipe boring grab, it is characterized in that, described fixture comprises base plate and top board, be fixed with several locating pieces between described base plate and top board, one end of described base plate has location-plate, there is several drill bushing holes on described top board, also there is at least one on described top board for compressing the compressing member of pipe.

This fixture, for clamping, fixing pipe, is holed to pipe.Pipe is located in the locating piece between top board and base plate, until an end of pipe is resisted against on location-plate, then uses compressing member to compress pipe, pipe is fixed on locating piece, simple in structure.Add man-hour, drill bit is processed pipe through the drill bushing hole of top board top, and because the drill bushing hole on top board need to be arranged according to the pipe bore position in advance, therefore, the machining accuracy of pipe boring is high.

In above-mentioned a kind of pipe boring grab, described compressing member comprises screw rod and rotating handles, and described rotating handles is connected in the top of screw rod by welding, has the screwed hole be complementary with described screw rod on described top board.Screw rod is located in screwed hole, and compressing member is threaded with top board, and rotating handles facilitates the screw rod rotation, by the rotation rotating handles, makes the bottom of screw rod be pressed in the pipe top, and pipe is fixed on locating piece, and pipe can not rock, and during boring, precision is high.

In above-mentioned a kind of pipe boring grab, described location-plate comprises backer and positioning head, and described backer is connected in an end of base plate, and described positioning head is fixed on the side of backer near locating piece.The backer, against an end of living pipe, makes the pipe axial location, and positioning head is embedded in pipe, and the internal diameter of the external diameter of positioning head and pipe is complementary, and pipe can not be rocked when holing, and borehole accuracy is high.

In above-mentioned a kind of pipe boring grab, on described locating piece, there is V-shaped groove.V-shaped groove more is conducive to pipe is positioned, and makes pipe be difficult for rocking, sliding.

In above-mentioned a kind of pipe boring grab, the quantity of described locating piece is three, and three locating pieces are a straight line arrangement.The quantity of locating piece is more than two, and for pipe is positioned, being a straight line is that this fixture is mainly used in clamping, secure rocker because pipe is long straight pipe.

In above-mentioned a kind of pipe boring grab, described drill bushing hole is a straight line and arranges.Be mainly used in adding the straight pipe of section chief.

Compared with prior art, a kind of pipe boring grab that the utility model provides has the following advantages:

1, have V-shaped groove on the locating piece of this pipe boring grab, long straight pipe is positioned at V-shaped groove, good stability; By the rotating handles rotating screw bolt, on screw rod, move while unclamping long straight pipe, pack into or take out long straight pipe, when screw rod descends the long straight pipe of compression, screw rod makes long straight pipe be fixed in V-shaped groove and carry out Drilling operation, simple in structure.

2, an end of this pipe boring grab base plate has the backer, makes long straight pipe energy axial restraint, and also has positioning head on the backer, and positioning head is embedded in long straight pipe, and make long straight pipe be held Shi Buhui and rock, good stability.

3, have default drill bushing hole in advance on the top board of this pipe boring grab, this drill bushing hole guarantees that pipe adds the machining accuracy in man-hour, and product rejection rate is low.
