Technical field
The utility model relates to a kind of drilling rod of rig of drilling well punching, especially adopts the castellated flange jointed rod of the rig of castellated flange connection.
Background technology
During engineering driller mainly is applicable to, the shallow bore hole drill hole sampling, can be used for also that engineering geologic investigation, the hydrology, well and bigbore engineering construction are crept into and the anchor hole construction; The rig of this kind structure, its kelly back connects driven drilling rod, along with going deep into of creeping into, needs constantly to increase driven drilling rod, and one one driven drilling rod interconnects the back and constitutes stem, guarantees going deep into of boring, meets the requirements of drilling depth.In drilling process, connect the driven drilling rod of another root a driven drilling rod back and need spend the regular hour, the length of this time directly determines the height of drilling efficiency, so require two jointings between the driven drilling rod not only simply, but also reliable, convenient and swift when connecting, shorten the time that attended operation needs, guarantee to transmit driving torque again simultaneously, guarantee drilling depth.The driven drilling rod of prior art connects by flange between two driven drilling rods usually, at the two ends of every driven drilling rod flange is set all, links together by bolt etc.; This kind structure, though it is convenient and swift in the time of guaranteeing to connect, shorten the time that attended operation needs, but need bear and transfer torque with bolt, and the intensity of bolt, material, processing technology etc. all determine bolt should not bear and transfer torque, otherwise bolt fractures easily, drilling operation is hindered, heavy then cause fracture accident, the part drilling rod is stayed in the hole, drilling construction can't be carried out.
The utility model content
The utility model is at bearing and transfer torque, bolt fracture easily and influence drilling operation and construct with bolt that the connection fit structure between the driven drilling rod of prior art exists, or bolt fracture that drilling construction can't be waited is not enough, provide a kind of quick and easy for installation, can shorten the time that attended operation needs, the castellated flange jointed rod of reliable delivery moment of torsion.
The technical solution of the utility model: the castellated flange jointed rod of rig comprises drilling rod cylindrical shell cylindraceous; It is characterized in that: at the two ends of drilling rod cylindrical shell, being respectively arranged with adpting flange and following adpting flange, at the end face of last adpting flange, being provided with the epirelief tooth that several are evenly arranged, is groove between the adjacent in twos epirelief tooth; End face at following adpting flange is provided with the following protruding tooth that equates with epirelief tooth quantity, and following protruding tooth is corresponding with the position of groove, is recess between adjacent in twos following protruding tooth; On last adpting flange and following adpting flange, all be provided with several bolts hole.
Further feature is: between last adpting flange, following adpting flange and drilling rod cylindrical shell, several ribs are set.
Ribs is evenly distributed on the drilling rod barrel outer surface.
On last adpting flange, sealed groove is set; In following adpting flange, hold-down ring is set.
Described epirelief tooth is three, and groove is three.
The castellated flange jointed rod of the utility model rig with respect to prior art, has following characteristics:
1, adopt the protruding tooth on the two ends of drill head, the structure that recessed tooth is connected mutually, convenient and fast connection between two driven drilling rods can shorten the time that attended operation needs significantly, improves drilling construction efficient, accelerates construction progress;
2, adopt the protruding tooth on the termination, the fit structure that recessed tooth is connected mutually, bear and transfer torque, play the effect of reliable delivery moment of torsion, guarantee that drilling construction normally carries out with protruding tooth, recessed tooth.
