Abstract
The utility model discloses a drill rod connecting rod which is composed of an integral cylindrical rod body. The cylindrical rod body comprises a drill bit connecting rod (2), a transition rod (3), a travel rod (5), a connecting rod (7) and a drilling machine connecting rod (9) in sequence. The cylindrical rod body is further provided with a through hole (1) which penetrates through the drill bit connecting rod (2) and the drilling machine connecting rod (9). Outer threads are arranged on a circumferential end face of the drill bit connecting rod (2) and a circumferential end face of the drilling machine connecting rod (9), the travel rod (5) and the connecting rod (7) are separated through a limiting ring (6), and a pin key groove (8) is further formed in the circumferential end face of the connecting rod (7). The drill rod connecting rod has the advantages of being not only convenient to assemble and disassemble, but also simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of oil drilling machine accessory, specifically is a kind of drilling rod connecting rod.
Background technology
Nowadays the drilling rod kind is more and more, and structure also has varied as required; Drilling rod not only needs stable rotating speed and bigger torque in rotation process, but also needs bending resistance folding endurance preferably, these not only have requirement to drilling rod, but also the connecting rod of drilling rod is also had requirement, the work of the structure influence drilling rod of connecting rod, so the effect of connecting rod is particularly important; Though present drilling rod connecting rod has reached good connectivity, performances such as intensity, corrosion-resistant and flexing resistance are also fine,, most connecting rod not only loads and unloads inconvenience when loading and unloading connect, and complex structure cost height.
The utility model content
Problem to be solved in the utility model provides a kind of drilling rod connecting rod, is used for solving drilling rod connecting rod loading and unloading inconvenience, complex structure and the high problem of cost.
The technical scheme that the utility model provides is: the drilling rod connecting rod, the cylinder body of rod by an integral body is formed, the cylinder body of rod includes drill bit connecting rod, transiting rod, stroke lever, connecting rod and five parts of rig connecting rod in turn, the cylinder body of rod also is provided with the through hole that runs through drill bit connecting rod and rig connecting rod, drill bit connecting rod and rig connecting rod circumferential end surfaces are provided with external screw thread, separate by spacing ring between stroke lever and the connecting rod, described connecting rod circumferential end surfaces also is provided with keyway.The effect of spacing ring is the stroke of the whole drilling rod connecting rod of restriction, thereby avoids the work of drilling rod connecting rod overtravel to damage drill bit or rig.
The circumferential end surfaces of described stroke lever and drill bit connecting rod junction also has fitting recess.The drilling rod connecting rod is clamped in the fitting recess place with external tool when assembling drilling rod and rig, thereby rotates drilling rod connecting rod, drill bit or rig by instrument, has not only made things convenient for dismounting, and can also well protect drilling rod connecting rod external surface not to be destroyed.
Described fitting recess is provided with two, evenly distributes each other.Instrument can symmetry clamp the drilling rod connecting rod when clamping, stress balance, and the workload that can reduce a staff, and also the instrument that can prevent skids in drilling rod connecting rod outer face.
Described transiting rod is conical structure, and a less end end face is circular end face, and circular end face connects the drill bit connecting rod.At work, the end that transiting rod connects the drill bit connecting rod is in the lower end, like this, in drilling process, the mud that gets out is under the influence of transiting rod conical structure, and easier making progress discharged, can not stop up drill bit, avoid the problem of the big and drilling rod breakage of the work quantitative change that causes too much because of mud.
The externally threaded screw thread effective length of described drill bit connecting rod and rig connecting rod is 8-13 centimetre.Screw thread need bear bigger axial tension effect when connecting, the insufficient strength that is threaded if the screw thread effective length is too short, thereby screw thread easily lost efficacy and causes accident to take place, and the long then waste material of screw thread effective length and increase cost are so the effective length of screw thread is decided to be 8-13 centimetre.
The thickness of described spacing ring is the 7-15 millimeter.Spacing ring can be subjected to axial pressure effect when spacing, thus when spacing ring thickness is low its easily fracture damage, think and guarantee that spacing ring satisfies its thickness of force request and gets arbitrary value between the 7-15 millimeter.
Advantage of the present utility model is: this drilling rod connecting rod of the utility model design, and not only easy to loading and unloading, and also simple in structure, cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Label among the figure is expressed as respectively: 1, through hole; 2, drill bit connecting rod; 3, transiting rod; 4, fitting recess; 5, stroke lever; 6, spacing ring; 7, connecting rod; 8, keyway; 9, rig connecting rod.
The specific embodiment
Embodiment 1
Referring to Fig. 1, the drilling rod connecting rod, the cylinder body of rod by an integral body is formed, the cylinder body of rod includes drill bit connecting rod 2, transiting rod 3, stroke lever 5, connecting rod 7 and 9 five parts of rig connecting rod in turn, the cylinder body of rod also is provided with the through hole 1 that runs through drill bit connecting rod 2 and rig connecting rod 9, drill bit connecting rod 2 and rig connecting rod 9 circumferential end surfaces are provided with external screw thread, separate by spacing ring 6 between stroke lever 5 and the connecting rod 7, and described connecting rod 7 circumferential end surfaces also are provided with keyway 8.
Described stroke lever 5 also has fitting recess 4 with the circumferential end surfaces of drill bit connecting rod 2 junctions.
Described fitting recess 4 is provided with two, evenly distributes each other.
Described transiting rod 3 is conical structure, and a less end end face is circular end face, and circular end face connects drill bit connecting rod 2.
The externally threaded screw thread effective length of described drill bit connecting rod 2 and rig connecting rod 9 is 8-13 centimetre.
The thickness of described spacing ring 6 is the 7-15 millimeter.
In use, drill bit connecting rod 2 is connected with drill bit, and rig connecting rod 9 is connected with rig, and rig and connecting rod 7 seas are locked by pin keies in the keyway 8, has increased torque force, has protected the junction, and structure is also more stable.
The adding of fitting recess 4 makes the staff when loading and unloading smooth work plane be arranged, can not damage the drilling rod connecting rod, and also more laborsaving and convenient.
The earth that the adding of transiting rod 3 makes drill bit get out can better be discharged, and can not stop up drill bit, fabulous protection drill bit, also reduced workload and rate of breakdown, practicality strengthens.
Can well realize the utility model as mentioned above.
