Abstract
The utility model relates to engineering machinery, and relates to part structures of a rotary drilling rig, in particular to an integral drive key sleeve type drill stem of the rotary drilling rig, which includes a sectional rod and a sectional rod pipe in sleeve joint, wherein a plurality of longitudinal key slots matched with key strips on an inner layer sectional rod are formed on the inner wall of the pipe body of the sectional rod pipe. The utility model has reasonable structure, particularly the key slots in an integral drive key sleeve can be processed mechanically; and the transmitted torque is large and the drill stem can stand wear and tear, therefore, the service life of the drive key sleeve can be prolonged, and the defects of the welding type drive key sleeve, such as multiple weld joints and susceptibility to deformation and damage can be overcome. The drill stem has the advantages of convenient processing, deformation prevention during machining process, and high mechanical strength.
Description
Technical field
The utility model relates to a kind of engineering machinery, relates to the modular construction of rotary drilling rig, specifically is a kind of whole key shell type rotary drilling rig drilling rod that drives.
Background technology
Rotary drilling rig in pile foundation basic engineering construction process, its run of steel is adjusted according to punching degree of depth different needs, adopt the mode of more piece rod tube layer overlaps and clamping, the external key bar of internal layer pole drives the interior keyway of key cover with adjacent outer pole lower end and matches, and carries out drilling and forming hole by unit head rotation transferring power.Drive the frequency of utilization height of key cover in the use, relative wear just than comparatively fast.The driving key cover of rotary drilling rig drilling rod of the prior art is partly formed by three: seamless pipe, internal key bar, arc plate.Be that the inwall that internal key bar and arc plate are welded on seamless steel pipe is formed the trisection keyway, shortcoming is that weld seam is many, easily produces welding deformation, and the mechanical strength of welding back material reduces, and application life is short.In the process that pressurization is reversed, the driving key of outer pole cover internal key bar cooperates with the external key bar of adjacent inner layer pole and carries out construction operation.The internal key bar easily comes off when driving the internal key bar weld seam serious wear of key cover, causes with bar, kelly and pounds the generation of bar phenomenon, influences the construction of whole engineering when serious.
Summary of the invention
Technical problem to be solved in the utility model is to provide the integral body of a kind of mechanical strength height, long service life to drive key shell type rotary drilling rig drilling rod.
Whole pole and the section rod tube that key shell type rotary drilling rig drilling rod includes mutual socket that drive of the present utility model has vertical keyway that key bar some and on the internal layer pole matches on the inboard wall of tube body of section rod tube.
The utility model is rational in infrastructure, keyway in the all-in-one-piece driving key cover can be finished by machining, its transmission is turned round big, wear-resistant, prolonged the application life that drives the key cover, overcome welded type and driven defectives such as the weld seam of key cover is many, yielding damage, have do not have in easy to process, the process be out of shape, advantage that mechanical strength is high.
Description of drawings
Fig. 1 is a cross section structure schematic diagram of the present utility model.
The specific embodiment
Whole pole 1 and the section rod tube 2 that key shell type rotary drilling rig drilling rod includes mutual socket that drive of the present utility model has vertical keyway 21 that key bar 11 some and on the internal layer pole matches on the inboard wall of tube body of section rod tube.In the use by cooperating of key bar 11 and keyway 21 can be between inside and outside layer pole transfer torque.
Claims (1)
1. an integral body drives key shell type rotary drilling rig drilling rod, and it includes the pole and the section rod tube of mutual socket, it is characterized in that: have vertical keyway that key bar some and on the internal layer pole matches on the inboard wall of tube body of section rod tube.
