The drill rod connecting sleeve includes sleeve bodies, wherein the sleeve body is arranged between the drive sleeve and the drill rod; a flange is arranged at the upper part of the sleeve body; a drill rod hole is arranged at the middle part of the sleeve body; a drive groove is arranged on the inner wall of the sleeve body; a drive key is arranged on the outer wall of the sleeve body; the diameter of the drill rod hole corresponds to the outer diameter of the drill rod; and the outer diameter of the sleeve body adapts to the diameter of the drill rod hole of the neighboring sleeve body. 4 sleeve bodies are adopted, the drill rod holes in the middle parts of the sleeve bodies correspond to the outer diameters of the 2nd, 3rd, 4th and 5th sections of the drill rod, and all the sleeve bodies are in mutual key connection. The utility model has the benefits that the drill rod connecting sleeve prolongs the service life of the drill rod, reduces the occurrence of machine fault, and has excellent use effect.
Description
Technical field
The utility model relates to the engineering instrument field, relates in particular to a kind of rotary drilling rig drilling rod adapter sleeve.
Background technology
Existing rotary drilling rig drilling rod is the parts of the transferring power on rotary drilling rig; Elongated is 5 joints; The heavily about 1.5-2.3 ton of every joint drilling rod, about the about 12-17 rice of the length of every joint drilling rod, every joint drilling rod is made up of seamless steel pipe and welding inner drive and outer drive key above that; Thereby unit head produces key through the acromere of self actuating sleeve and drilling rod to be connected on the continuous drill bit of the torque tube of unit head, and the drive drill bit carries out excacation.But the whole about 8-10 ton of weight of 5 joint drilling rods, rotary drilling rig need constantly move up and down by the drilling rod that the 8-10 ton is heavy when work, when the drilling depth of being dug is more shallow; 5 joint drilling rods can not carry out disassembly and assembly; Still need be installed on the unit head, still need drive the weight of 5 joint drilling rods during work, not only waste power and resource in a large number; And cause the load and the wearing and tearing of associated components, thereby be prone to send out a mechanical breakdown.
The utility model content
The above-mentioned deficiency that the utility model exists to prior art; Novel rotary drilling rig drilling rod adapter sleeve is provided; He has broken through the limitation of prior art, has realized arbitrarily reducing the purpose that drilling rod alleviates drilling rod weight, and the difficulty that people can't be overcome for a long time is resolved.It can easily save drilling rod and directly be enclosed within on the unit head actuating sleeve each; Realized selecting the drilling rod of corresponding joint number according to the requirement of work yardstick; The overall weight of drilling rod when having alleviated machine works accomplishes to have improved operating efficiency because of the different mining of the drilling depth drilling rod with different joint numbers.
The purpose of the utility model is to realize through following technical scheme:
A kind of rotary drilling rig drilling rod adapter sleeve comprises body, and said body is arranged between actuating sleeve and the drilling rod; Said body top is provided with flange; The body middle part is provided with the drilling rod hole, and the body inwall is provided with driver slot, and the body outer wall is provided with the driving key; Said drilling rod bore dia is corresponding with the drilling rod external diameter, and the drilling rod bore dia of said body external diameter and adjacent body adapts.Said body is provided with 4, and the drilling rod bore dia that said body middle part is provided with connects the mutual key of each body respectively at corresponding with the 2nd, 3,4,5 joint drilling rod external diameters.
The utility model beneficial effect: simple in structure, easy for installation, cost is low, reduce oil consumption, also reduced the load and the wearing and tearing of associated components, prolong rig application life, increased the application life of drilling rod, reduced the generation of mechanical breakdown, result of use is good.
Description of drawings
Fig. 1 is the described rotary drilling rig drilling rod of a utility model adapter sleeve structural representation.
Among the figure:
1, body; 2, flange; 3, drilling rod hole; 4, driver slot; 5, drive key.
The specific embodiment
According to accompanying drawing and embodiment the utility model is done further explain below.
At first the rotary drilling rig principle is: rotary digging drill power head is to drilling rod and be installed in drilling tool on the drilling rod and send to revolve and dig moment of torsion, thereby accomplishes the dynamogenic output device of bore operation.Unit head is accepted the power that the motor of rotary drilling rig sends, and is converted into to revolve through hydraulic motor and reducer and digs moment of torsion, will revolve through power shaft, gear ring, actuating sleeve etc. and dig the drilling tool that moment of torsion passes to drilling rod and is connected with drilling rod.
As shown in Figure 1, a kind of rotary drilling rig drilling rod of the utility model adapter sleeve is taked the mode of casting when making; Comprise body 1, said body 1 is arranged between the actuating sleeve and drilling rod of unit head connection, and said body 1 top is provided with flange 2; Body 1 middle part is provided with drilling rod hole 3; Body 1 inwall is provided with driver slot 4, and body 1 outer wall is provided with and drives key 5, and said drilling rod hole 3 diameters are corresponding with the drilling rod external diameter.Adapter sleeve is made 4; The internal diameter of 4 adapter sleeves just drilling rod hole 3 diameters adapts with the 2nd joint, the 3rd joint, the 4th joint, the 5th joint drill pipe diameter respectively; Topmost structure is internal diameter drilling rod hole 3 diameters just of confirming body 1 according to the external diameter of every joint drilling rod; Just come to confirm respectively drilling rod hole 3 diameters according to the external diameter size of the 2nd joint, the 3rd joint, the 4th joint, the 5th joint drilling rod; The interior diameter of the external diameter of splicing sleeve and adjacent pipe box adapts; Be provided with driver slot 4 in the adapter sleeve tube wall and adapt with the outer driving key 5 of connecting rod, adapter sleeve tube wall outside is provided with the driving key 5 sleeve interior driver slots 4 adjacent with another one and adapts, and the adapter sleeve tube wall outside of outermost end drives key 5 and adapts with actuating sleeve.The mutual key of each splicing sleeve is connected, and interfix through flange 2.
At first according to the degree of depth of the driller of institute journey, select appropriate length in use, for example only select 2 joints, 3 joints or 4 joint drilling rods; Then adapter sleeve is enclosed within on the actuating sleeve; And fixing through flange 2, and insert one by one each other adapter sleeve is descending successively, when the internal diameter of branch sleeve just the diameter of drilling rod hole 3 diameters and selected drilling rod at once; Directly drilling rod is enclosed within on the adapter sleeve; Realized that unit head drives actuating sleeve and drilling rod is worked simultaneously, saved other unwanted drilling rod, when the degree of depth of work changes, can adapter sleeve have been taken off; Install the drilling rod of corresponding joint number, realized that drilling rod selects the drilling rod of different joint numbers according to the demands of different of institute's working depth.Alleviated drilling rod weight savings dynamic property, improved operating efficiency, prolonged the application life of rig.
