Abstract
The utility model provides a reinforced type drilling rod, comprising a tube-shaped drilling rod body and drilling rod joints which are respectively disposed at two ends of the drilling rod body and conduct upsetting process on the two ends of the drilling rod body. The reinforced type drilling rod is advantageous in that the reinforced type drilling rod is prepared by adopting the upsetting process, and thereby the drilling rod joint is integrated with the drilling rod body; coaxiality of the integral drilling rod can be effectively guaranteed, and power transmission can be ensured; the integral strength of the drilling rod can be effectively guaranteed, and the drilling rod can be prevented from being cracked in practical work; effect to production and engineering accidents can be prevented, and the service lifetime of the drilling rod is substantially prolonged; machining process can be effectively simplified and production efficiency can be improved; the structure is simple, producing is convenient, cost is low, and popularization is easy.
Description
Technical field
The utility model relates to a kind of drilling rod, relates in particular to a kind of reinforced drilling rod.
Background technology
Drilling rod is to connect the rod member of boring bar tool and drill bit and transmit power when bore operation, and is widely used in builing industry, the mining industry.The joint composition that traditional drilling rod adopts steel pipe and the steel pipe two ends are set, adopt heavy wall type pipe fitting to carry out screw thread earlier and be processed into joint, again joint is welded on the two ends of steel pipe, there is following defective in the drilling rod of this structure: at first, the joint that adds job number earlier is welded on the two ends of steel pipe, be difficult to the axiality between two joints of assurance and the steel pipe like this, influence the transmission of power; Secondly, joint is owing to be the two ends that are welded on steel pipe, so the bulk strength of drilling rod is difficult to guarantee, causes easily fracture occurring in the practical application of drilling rod, causes engineering accident, thereby influence the application life of drilling rod, influence production; At last, the process complexity influences working (machining) efficiency.
Therefore, need to propose a kind of novel drilling rod, can guarantee the axiality of drilling rod integral body effectively, guarantee the transmission of power, can guarantee the bulk strength of drilling rod effectively, avoid drilling rod fracture in real work, to occur, avoid production is impacted and engineering accident, prolong the application life of drilling rod, but also can effectively simplify process, enhance productivity.
The utility model content
In view of this, a kind of reinforced drilling rod that the utility model provides, can guarantee the axiality of drilling rod integral body effectively, guarantee the transmission of power, can guarantee the bulk strength of drilling rod effectively, avoid drilling rod fracture in real work, to occur, avoid production is impacted and engineering accident, prolong the application life of drilling rod, but also can effectively simplify process, enhance productivity.
The reinforced drilling rod that the utility model provides comprises the drilling rod body of tubular structure and is arranged at tool joint drilling rod body two ends and that pass through drilling rod body two ends are adopted the formation of jumping-up technology;
Further, the external diameter of described tool joint is identical with the external diameter of drilling rod body, and the internal diameter of described tool joint is less than the internal diameter of drilling rod body;
Further, the inside wall of described tool joint is provided with connecting thread.
The beneficial effects of the utility model: the reinforced drilling rod that the utility model provides, adopt the jumping-up processes to make, make tool joint and the setting of drilling rod body integral type, can guarantee the axiality of drilling rod integral body effectively, the transmission of assurance power; Can guarantee the bulk strength of drilling rod effectively, avoid drilling rod fracture in real work, to occur, avoid production is impacted and engineering accident, prolong the application life of drilling rod widely, but also can effectively simplify process, enhance productivity; The utility model is simple in structure, and is easily manufactured, with low cost, is easy to promote.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the utility model structural representation.
The specific embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure, the reinforced drilling rod that the utility model provides comprises the drilling rod body 1 of tubular structure and is arranged at tool joint 2 drilling rod body 1 two ends and that pass through drilling rod body 1 two ends are adopted the formation of jumping-up technology; The reinforced drilling rod that the utility model provides adopts the jumping-up processes to make, and makes tool joint and the setting of drilling rod body integral type, can guarantee the axiality of drilling rod integral body effectively, the transmission of assurance power; Can guarantee the bulk strength of drilling rod effectively, avoid drilling rod fracture in real work, to occur, avoid production is impacted and engineering accident, prolong the application life of drilling rod widely, but also can effectively simplify process, enhance productivity; The utility model is simple in structure, and is easily manufactured, with low cost, is easy to promote.
In the present embodiment, the external diameter of described tool joint 2 is identical with the external diameter of drilling rod body 1, the internal diameter of described tool joint 2 is less than the internal diameter of drilling rod body 1, this structure, can guarantee the mechanical strength of tool joint 2 and drilling rod body 1, be beneficial to the processing of the screw thread of follow-up tool joint, the intensity that makes it the tool joint after the machining screw still can access effective assurance.
In the present embodiment, the inside wall of described tool joint 2 is provided with connecting thread, and the setting of connecting thread is easy to the connection of drilling rod, improves installation effectiveness.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
