This drilling tool by adpting flange (1), flange reinforcing rib (2), go up suspension card (3), mandrel junction plate (4), safety rigging (5), safe cable clamp (6), spiral mandrel (7), helical blade (8), cutting element (9), suspension card (10), centering plate (11) are formed down.Said mandrel junction plate, said spiral mandrel, said centering plate and said helical blade are formed the spiral drill parts; Said spiral mandrel upper end is fixedly connected with said mandrel junction plate lower end, is fixedly connected on lower end and the said centering plate, and said helical blade internal diameter is fixedly connected with said spiral outside diameter of mandrel, and the upper end is fixedly connected with said mandrel junction plate lower end; Said mandrel junction plate upper end is fixedly connected with said adpting flange; Said safety rigging upper end and the said suspension card connection that goes up are passed from spiral mandrel inside, lower end and said suspension card connection down, and several said safety cable kayser stressed joints are used at two ends respectively, form safety guard; Said flange reinforcing rib is fixedly connected with said adpting flange and said spiral drill parts; Said cutting element is separately fixed at the outer end of helical blade and the lower end of centering plate.
Preferably, said upward suspension fastens below adpting flange, and the cross section of last suspension card is circle or polygon.
Preferably, said suspension down fastens on centering plate, and following suspension card face shaping is the U type, and its cross sectional shape is circle or polygon.
Preferably, said safety rigging is wire rope or iron chains.
Preferably, the junction of said safety rigging and last suspension card and following suspension card is used several safety cable kayser stressed joints respectively.
In revolving the excavation construction process, the adpting flange of short spiral drill and the drilling rod of rotary drilling rig are connected through bearing pin, when damaged conditions such as spiral mandrel generation fracture; The spiral drill parts and the drilling tool main body of below, impaired place are broken off; On when carrying drilling tool the spiral drill parts of below, said impaired place break away from said drilling tool main body, this moment and last suspension card and down the safety rigging that is connected of suspension card strain safety guard work; The drilling tool parts that drive below, impaired place are up with the drilling tool main body; Outside proposing the hole, unload said bearing pin afterwards, will lack spiral drill and rotary drilling rig drilling rod and break away from.
The beneficial effect of the utility model is a kind of short spiral drill of built-in safeguard protection device; When in the work progress during helix core axle fracture; The drilling tool parts fracture back of avoiding below, impaired place falls into the disengaging of drilling tool main body thereby drilling accident takes place in the hole, improves drilling efficiency, reduces drilling cost.
