Description

A kind of drilling rod adopting taper pipe thread and spline slide sleeve to be connected
Technical field
The utility model relates to a kind of drilling rod, and the joint of this drilling rod adopts taper pipe thread and spline slide sleeve to be connected, and belongs to pile works mechanical field.
Background technology
In building piling process, drilling rod is a kind of connection drill bit, in order to transmit the rod member of power.The upper and lower drilling rod connected mode of current drilling rod has: flange is fixedly connected with, six square joints or spline joint etc., these connected modes all ubiquity install trouble, the problem that upper and lower drilling rod is difficult with one heart, in addition, it is little that the drilling rod adopting above-mentioned connected mode to obtain also has transmission torque, run jiggly problem, therefore the exploitation of drilling rod that is large, that operate steadily of a kind of transmission torque is necessary.
Utility model content
Utility model object: technical problem to be solved in the utility model is to provide a kind of upper and lower drilling rod easy accessibility, transmission torque is large, the drilling rod operated steadily.
Utility model content: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of drilling rod adopting taper pipe thread and spline slide sleeve to be connected, comprise interconnective upper drilling rod and lower drilling rod, described upper drilling rod is provided with the externally threaded male joint of band in tool joint place, described lower drilling rod is provided with tapped female joint in tool joint place, described male joint and female joint are arranged with one heart, and connected by threaded engagement, also comprise spline slide sleeve and positioner, described spline slide sleeve is enclosed within the periphery of tool joint, described lower upper drilling rod is provided with groove, described spline slide puts and is provided with the hole isometrical with groove, described groove and described hole one_to_one corresponding, described positioner inserts in described groove through described hole.
Further preferred, the cross section of described male joint and female joint is all tapered.
Beneficial effect: compared to prior art, drilling rod of the present utility model can realize connection and the dismounting of upper and lower drilling rod easily; Secondly, the male and female Taper Pipe joint arranged with one heart in drilling rod adopts and is threaded, and not only ensures that upper and lower drilling rod connects closely, and also ensure that drilling rod in use operates steadily; Finally, the spline slide sleeve being located at joint strengthens the Connected degree of upper and lower drilling rod further, is greatly ensureing the driving torque basis that upper and lower drilling rod is connected firmly also further enhancing drilling rod.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model drilling rod;
Fig. 2 is the upper jackrod structure schematic diagram of the utility model drilling rod;
Fig. 3 is the lower jackrod structure schematic diagram of the utility model drilling rod;
Fig. 4 is the structural representation of spline slide sleeve in the utility model drilling rod.
Detailed description of the invention
Below in conjunction with detailed description of the invention and accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ 4, the drilling rod that the utility model adopts taper pipe thread and spline slide sleeve to be connected, comprise interconnective upper drilling rod 1 and lower drilling rod 2, male joint 3 and female joint 4 is provided with in the junction of upper drilling rod 1 and lower drilling rod 2, male joint 3 is positioned at tool joint place of drilling rod 1, external screw thread is with in male joint 3, female joint 4 is positioned at tool joint place of lower drilling rod 2, internal thread is with in female joint 4, the cross section of male joint 3 and female joint 4 is all tapered, and arrange with one heart, male joint 3 is connected by threaded engagement with female joint 4, the male joint 3 arranged with one heart in drilling rod and female joint 4 adopt and are threaded, not only ensure that the connection of drilling rod 1 and lower drilling rod 2 is tight, and also ensure that drilling rod in use operates steadily, drilling rod of the present utility model also comprises spline slide sleeve 5 and positioner 6(is also fastening devices 6), spline slide sleeve 5 is enclosed within the periphery of tool joint, upper drilling rod 1 is provided with groove 7, spline slide sleeve 5 is provided with the hole 8 mutually corresponding with groove 7, spline slide sleeve 5 also will upwards slide in drilling rod 1 direction (namely in Fig. 1 to the right) after tool joint connects, the hole 8 slid on spline slide sleeve 5 is corresponding with the groove 7 on upper drilling rod 1, lock by fastening devices 6 again, positioner 6 inserts in groove 7 through hole 8, positioner 6 and groove 7 can adopt threaded engagement to be connected, and then spline slide sleeve 5 is fixed on tool joint place, the spline slide sleeve 5 being located at tool joint place strengthens the Connected degree of drilling rod 1 and lower drilling rod 2 further, greatly ensureing the driving torque basis that drilling rod 1 and lower drilling rod 2 are connected firmly also further enhancing drilling rod.
Drilling rod of the present utility model can realize connection and the dismounting of upper and lower drilling rod easily; The female joint 4 of the male joint 3 of upper drilling rod 1 and lower drilling rod 2 is docked and mutually rotated, upper drilling rod 1 and lower drilling rod 2 are coupled together by the screw thread cooperatively interacted by male joint 3 and female joint 4, upper and lower drilling rod is fixedly connected with by periphery that male joint 3 is enclosed within tool joint by spline slide sleeve 5 after being rotated in place with female joint 4 again further, positioner 6 and groove 7 can adopt threaded engagement to be connected, and then spline slide sleeve 5 is fixed on tool joint place.
Drilling rod of the present utility model shows through field trial: it has, and easy accessibility is rapid, good seal performance, drilling rod are connected firmly, transmission torque is large, run the advantages such as attitude is steady.
Above-mentioned embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not limited by the examples; other are any do not deviate from Spirit Essence of the present utility model and principle under do change, modification, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
