Abstract
The invention relates to an adjustable-length drill pipe structure comprising a drill pipe body with both ends in threaded connection with joints. The adjustable-length drill pipe structure is simple in structure and rapid and convenient to mount. Through the joints arranged at two ends of the drill pipe, direct connection between the drill pipes is avoided, the threaded connection is convenient and rapid, and accordingly, input cost of enterprises is saved greatly, and the service life of the drill pipe is prolonged.
Description
Technical field
The present invention relates to geological prospecting apparatus field, relate in particular to a kind of length-adjustable jackrod structure.
Background technology
Drilling rod is mainly used for connecting in the industries such as geological prospecting, drilling well drill bit, in order to the rod member of transferring power, for the darker exploration operation in stratum, all need being connected of drilling rod and drilling rod, to reach desired depth, but drilling rod is connected and dismantles the application life that has greatly shortened drilling rod with the frequent of drilling rod, drilling rod just needs drilling rod customized again after scrapping, greatly increased the input cost of enterprise.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, provide a kind of simple in structure, connect reliable length-adjustable jackrod structure, not only provide cost savings, also improved the application life of drilling rod.
The technical solution adopted in the present invention is as follows:
A length-adjustable jackrod structure, comprises the drilling rod body of rod, and catcher is threaded respectively in the two ends of the described drilling rod body of rod.
Its further technical scheme is:
Described catcher is connected and composed by the interior circle connecting each other and outer circle, described outer circle interior week internal thread is set, in the periphery of described interior circle, external screw thread is set;
The external diameter of described outer circle equates with the external diameter of described drilling rod club shaft;
The external diameter of described interior circle is less than the external diameter of described outer circle.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, it is quick and convenient to install, and by catcher being set in two ends of drill, effectively avoided drilling rod to be connected with the direct of drilling rod, and the mode being threaded is quick and convenient, has greatly saved the input cost of enterprise, has also improved the application life of drilling rod simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes the drilling rod body of rod 1, catcher 2 is threaded respectively in the two ends of the drilling rod body of rod 1.Catcher 2 is connected and composed by the interior circle 203 connecting each other and outer circle 204, outside circle 204 internal thread 201 is set in interior week, in the periphery of interior circle 203, external screw thread 202 is set.The external diameter of outer circle 204 equates with the external diameter of drilling rod club shaft 1.The external diameter of interior circle 203 is less than the external diameter of outer circle 204.
Concrete installation process of the present invention is as follows:
Because one end of the drilling rod body of rod 1 arranges external screw thread, the other end arranges internal thread, only catcher 2 one end with external screw thread 202 need to be connected with the female end of the drilling rod body of rod 1 when mounted, catcher 2 one end with interior spiral shell 201 are connected with the male end of the drilling rod body of rod 1, can realize catcher 2 and being threaded of the drilling rod body of rod 1, on stratum during darker drilling operation, only the catcher 2 at each drilling rod body of rod 1 two ends need to be connected and can realize the lengthening to the drilling rod body of rod 1 each other, during dismounting, be threaded connection to realize in each drilling rod body of rod 1 and take over 2 dismounting, effectively avoided drilling rod to be connected with the direct of drilling rod, the mode being threaded is quick and convenient, greatly saved the input cost of enterprise, also improved the application life of drilling rod simultaneously.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to basic structure of the present invention in the situation that, the present invention can do any type of modification.
