Abstract
The utility model relates to a hexagonal outer circle drill stem device for deep hole drilling under over-medium-hard geological conditions. The hexagonal outer circle drill stem device structurally comprises a drill stem hexagonal male connector, a round drill stem body, and a drill stem hexagonal female connector. The drill stem hexagonal male connector is connected with the drill stem hexagonal female connector through the round drill stem body, a clamping bean pin hole and a horizontal drill stem locating pin hole are formed in the lateral face of the drill stem hexagonal female connector, and a horizontal drill stem spring locating pin is arranged inside the horizontal drill stem locating pin hole. The hexagonal outer circle drill stem device is reasonable in design, compact in structure, convenient to operate, fast to connect and wide in range of application. Due to the fact that a hexagonal connecting mode is adopted in the drill stem connectors, torque and comprehensive mechanical performance of a drill stem under the condition of the same diameter reach the optimal allocation. Due to the fact that the horizontal drill stem spring locating pin is adopted in connection, the phenomena that thread-type drill stem threads are blocked and a screw head is twisted off are effectively avoided, and meanwhile, the horizontal drill stem spring locating pin is fast and convenient to assemble and disassemble, time and labor are saved and working efficiency is greatly improved.

The specific embodiment
With reference to the accompanying drawings embodiment of the present utility model is further described
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the probing of tunnel, a kind of colliery connects the cylindrical boring rod set soon with six sides, its structure comprises drilling rod six side's male joints 1, round drill rod body 2, drilling rod six side's female joints 4, described drilling rod six side's male joints 1 are connected with drilling rod six side's female joints 4 by round drill rod body 2, described drilling rod six side's male joints 1 are the outer hexagonal structure of hollow, the front end of described drilling rod six side's male joints 1 is provided with seal groove 13, the side of described drilling rod six side's male joints 1 is provided with semicircle cotter way 11, described drilling rod six side's female joints 4 are hexagonal structure in the hollow, described drilling rod six side's female joints 4 built-in sealing shrouds 3, described drilling rod six side's female joints 4 sides are provided with card beans pin-and-hole 5 and horizontal drilling rod dowel hole 6, be provided with horizontal drilling rod spring holder 12 in the described horizontal drilling rod dowel hole 6, described horizontal drilling rod spring holder 12 is by shank 7, card beans pin 8, back-moving spring 9 and pad 10 are formed, the two ends of described horizontal drilling rod dowel hole 6 can be U-shapeds, square or circular, described shank 7 is cylindrical, the one end is provided with square or step cutting pattern, and described round drill rod body 2 is circular hollow steel tube.
Be linked in sequence by drilling rod six side's male joints, drilling rod six side's female joint two ends between two cylindrical drilling rods, after two cylindrical drilling rods are pegged graft, on the card beans pin-and-hole that drilling rod six side's male joints, drilling rod six side's female joints overlap, press card beans pin, load onto horizontal drilling rod spring holder, card beans pin is upspring automatically and is upspring sealedly in card beans pin-and-hole, and drilling rod connects to be finished.Forward thrust during the cylindrical rod boring is by two end face carryings of drilling rod six side's male joints, drilling rod six side's female joints, rotary torsion during rod boring is by the six sides carrying of drilling rod six side's male joints, drilling rod six side's female joints, laterally the boring of drilling rod spring holder carrying drilling rod finish when fetching drilling rod to the pulling force that returns, card beans pin does not carry torsion and pulling force, only controls not mobile coming off of horizontal drilling rod spring holder.Laterally drilling rod spring holder built-in design on drilling rod, the friction damage of having avoided the bolt type connecting pin when the drilling rod rotary drilling shank to be produced simultaneously, because of not at drilling rod outside exposed nut or nut, greatly reduces the rotational resistance of drilling rod.Compare with bolt type drilling rod pin, quick and easy for installation, time saving and energy saving, each plug-in mounting connect hours only is 10-20 second, compares with the each 3-5 of original bolt connecting mode minute greatly and accelerates, and connects safety firmly, stability is high, and the drilling rod moment of torsion is big, bears the drag load height.The drilling rod mesopore can ventilate, water flowing, carries out the cooling of deslagging and drilling tool.The utility model can be widely used in the deep hole of medium ground, tunnel, colliery and coal petrography and visit water, mash gas pumping drilling construction, for safe improvement work such as the tunnel deep drilling of the prominent mine of height and gas drainage under suction provide boring tool efficiently, also can be applicable to the ground drilling operation operation of engineering infrastructures such as highway, railway, easy to implement and the popularization of the utility model has good economic benefit and social benefit.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
The technology that the utility model is not described in detail, shape, structure partly are known technology.
