Make supporting plate 51 and the top of motion bar 34 to drilling tool medial movement, and promote movable block 31 to move down, so as to extrude compression bullet
Spring 32, then compression spring 32 apply upward power to movable block 31, make movable block 31, motion bar 34 and supporting plate 51 have to
The trend of outside movement, can make supporting plate 51 apply a thrust on stake holes inwall, and the reaction force of stake holes inwall can drive
Drilling tool is returned to correct position, so as to improve the uniformity in stake holes direction, realize the preferable effect of uniformity in pore-forming direction.
The middle part of guide pile 61 is provided with the impact block 64 hit that can be fallen by drilling tool, and the bottom of support 10 is provided with can be with impact block 64
The baffle plate 22 of abutting.When baffle plate 22 moves down with drilling tool, abutted with impact block 64 and pass to a part of impulsive force of drilling tool
Guide pile 61, guide pile 61 is set to be driven underground downwards, guide pile 61 is driven underground and immovable, so that drilling tool bottom is begun
All morning to the bottom of stake holes, keeps correct posture.
The top of guide pile 61 is provided with limited block 65, can be abutted when drilling tool is pulled up after-poppet 10 with limited block 65, so that will
Guide pile 61 together pulls out stake holes.The bottom of guide pile 61 is provided with guide surface 62, and guide surface 62 is provided with for barrier-breaking
Projection 63.Guide surface 62 can make guide pile 61 be easier to be driven underground, and projection 63 can be advantageous to crush on barrier, in certain journey
Resistance when guide pile 61 is driven underground is reduced on degree.The upper end of limited block 65 is provided with fillet 66, when steel wire rope 72 moves up and down simultaneously
When being contacted with limited block 65, fillet 66 can reduce the frictional force between steel wire rope 72 and limited block 65, so as to prevent steel wire rope
72 are limited the scratch of block 65 and influence the service life of steel wire rope 72.
Specific implementation process：Before drilling is started, guide pile 61 is first inserted vertically into the position of stake holes center, Ran Houyong
Steel wire rope 72 lifts drilling tool, then makes drilling tool free-falling, starts to drill.During drilling tool falls in stake holes, if
Drilling tool shifts, and supporting plate 51 is touched stake holes inwall and makes supporting plate 51 and the top of motion bar 34 sidesway into drilling tool
It is dynamic, and promote movable block 31 to move down, so as to extrude compression spring 32, then compression spring 32 applies upwards to movable block 31
Power, motion bar 34 and supporting plate 51 have the trend opened laterally, supporting plate 51 can be made to apply one on stake holes inwall
Thrust, and the reaction force of stake holes inwall can drive drilling tool to return to correct position, it is real so as to improve the uniformity in stake holes direction
The preferable effect of uniformity in ready-made hole direction.
When drilling is finished, it is necessary to when drilling tool is withdrawn out of stake holes, drilling tool is pulled up with steel wire rope 72, makes support 10
Limited block 65 is abutted to, drives guide pile 61 together to move up, leaves stake holes., also can be by adjustable plate when without using drilling tool
24 are moved to extreme lower position, draw close the upper end of motion bar 34, reduce the space that drilling tool takes, are moved easily and deposit so as to play
The effect put.
