Abstract
The utility model relates to a drill rod coupling of drilling engineering. After an upper coupling 2 is sheathed in a lower coupling 1, the drill rod coupling is tightly clamped by a left retainer ring 3 and a right retainer ring 4 and is fixed through a positioning pin shaft 5 and a rounded end threaded rod 6; when the drill rod needs to be taken off, only the rounded end threaded rod 6 and a nut need to be loosened and rotated 45 DEG; the left snap ring and the right snap ring are opened and taken out, and the upper coupling and an upper drill pipe are taken out. The utility model has the advantages of reliable connection, big transmission torque, strong lifting capacity, convenient disassembling and assembling, labor intensity lightening, and long service life. The utility model is especially suitable for the connection of the drill rod with large caliber engineering drill holes.
Description
The utility model relates to a kind of tool joint of geological drilling engineering, particularly adapts to the drilling rod coupling head of heavy caliber engineering the drilling.
At present, what the tool joint of drilling project was adopted is to wait thread form taper thread connector, and during owing to probing, the moment of torsion that drilling rod and joint bear is bigger, strength of joint is not enough, easily cause the distortion of joint, when drilling rod need be dismantled, the joint screw thread was not torn open not got off, need with bigger labour intensity, just drilling rod can be taken off, this joint was both wasted time and energy, and damaged easily again.Chinese patent 90205888.6 discloses a kind of " tool joint of addendum cone formula ", it only is the medium thread form taper thread of prior art to be changed into do not wait the thread form taper thread, the end solves substantive issue, adopt this tool joint still to exist dismounting extremely inconvenient, labour intensity is big, shortcomings such as joint is fragile, it is not suitable for the engineering the drilling that the probing bore is big, load is heavy, moment of torsion is big.
The purpose of this utility model provides a kind of tool joint that adapts to the heavy caliber engineering the drilling, and not only transfer torque is big for it, and convenient disassembly, long service life.
The purpose of this utility model is achieved in that top connection and the lower contact that will be drilled with endoporus match, and wherein top connection is inserted in the lower contact, blocks lower contact with left snap ring and right snap ring, with location lock shaft and round end screw rod two snap rings is reinforced again.
The utility model is used for connecting drilling rod up and down, wherein goes up drilling rod and is fitted in the top connection, and following drilling rod is packed in the lower contact, tightens with left and right snap ring, reinforces by alignment pin and round end screw rod again.When drilling rod need take off, only need round end screw rod and nut are unclamped rotation 45 degree; Left and right snap ring is opened, can and go up drilling rod and take off top connection.
Adopt such scheme, connect reliably, transfer torque is big, and hoisting power is strong, and convenient disassembly reduces labor intensity greatly, shortens the lay day, long service life, and the drilling rod that adapts to the heavy caliber engineering the drilling especially connects.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 1, Fig. 2 also are embodiment of the present utility model.
In Fig. 1, Fig. 2, the utility model is made up of top connection 2, lower contact 1, left snap ring 3, right snap ring 4, alignment pin 5, round end screw rod 6, sealing ring 7.Wherein top connection 2 is inserted in the lower contact 1, and top connection 2 matches with lower contact 1 and locates to be connected for hexaplanar, and the end face that joins has sealing ring 7.Left side snap ring 3 and right snap ring 4 are stuck in the cannelure of lower contact external surface.Wherein left snap ring 3 directly is connected through alignment pin 5 with 4 one of right snap rings, and one is connected with alignment pin 5 by round end screw rod 6.
The drilling rod that the utility model is used for the large diameter drilling engineering the drilling connects, and joint joint drilling rod can link up one by one with the utility model, and the termination connects drill bit just can carry out probing work.In the time of drilling rod need being regained after probing finishes, the utility model and drilling rod one can be lifted out successively hole outside, the workbench that is put in prior art is put down, round end screw rod 6 and nut are unclamped, rotation 45 degree take off, and left snap ring 3 and right snap ring 4 are opened taking-up, can propose top connection 2 and last drilling rod, move in circles, just can easily drilling rod be disassembled one by one.
Claims (3)
1, a kind of geologic drilling rod joint, comprise top connection (2), lower contact (1), it is characterized in that top connection (2) is inserted in the lower contact (1), block lower contact, through location lock shaft (5) and round end screw rod (6) two snap rings are reinforced again with left snap ring (3) and left snap ring (4).
