Detailed description of the invention
Below in conjunction with drawings and Examples, description concrete is in detail done to the utility model, but protection domain of the present utility model is not limited to following examples.
Embodiment 1: the utility model provides a kind of locking device hanging detecting instrument for drilling rod inner chamber, and its structure as shown in Figure 1, 2, is provided with two external members 1 that narrow, axle center screw rod 5 and nuts 4; Described two external members 1 that narrow are for symmetrical structure, two external member external surfaces that narrow are equipped with axially crosses tank 2 and circumferential teeth 3, cross tank 2 for providing passage, the contact friction force that teeth 3 are locked for increasing narrow external member and drilling rod inwall for drilling fluid flowing; It is cylindric that two external members 1 that narrow combine rear appearance, and the external member inwall 7 that narrows after combination is up big and down small open circles frustum; Described axle center screw rod 5 is upper cone body 8, bottom is the conjoined structure of screw rod, and cone 8 is also up big and down small, and the screw rod of axle center screw rod 5 bottom is used for hold-down nut 4 and hangs detecting instrument 6; Nut 4 is the locking nut supporting with axle center screw rod 5 bottom screw rod; When device uses, be arranged on the male joint 13 of two drilling rod A10 of adjacent connection and the junction of the female joint 11 of drilling rod B12.
The cone 8 on described axle center screw rod 5 top is identical with the tapering of the open circles frustum of latter two external member inwall 7 that narrows of combination, diameter bottom cone 8 is larger than the diameter bottom open circles frustum, the height of the cone of the present embodiment axis screw rod upper end only narrow external member length 3/5ths, when two external members that narrow of combination are completely closed, external diameter is less than fillet of tool joint pins internal diameter.
The detecting instrument 6 hung in described device, is provided with the installing hole 9 matched with axle center screw rod at its upper end, is provided with internal thread for detecting instrument 6 is locked at axle center screw rod 5 lower end in installing hole.
The external member 1 that narrows two, device of the present utility model combines completely closed rear external diameter and is less than fillet of tool joint pins 13 internal diameter.Installation steps are:
(1) the external member 1 that, with two narrows encases the cone 8 of axle center screw rod 5, and adjustment makes cone 8 be arranged in the upper end of two external members that narrow, and such two external members 1 that narrow just are in complete closure state.
(2), two external members 1 that narrow closed completely encasing axle center screw rod 5 are installed to fillet of tool joint pins 13 port inner chamber.
(3), pull down axle center screw rod 5, and screw in nut 4 by axle center screw rod 5 lower end screw rod, nut 4 is to the external member 1 lower end precession that narrows, push the external member 1 that narrows upwards to move, when the cone external diameter that the frustum of a cone internal diameter moving to two external member inwalls 7 that narrow is less than, two external members 1 that narrow are opened by top and are clamped at fillet of tool joint pins 13 inwall gradually, and the apparent circumferential teeth of the external member that now narrows 1 can increase the contact friction force that narrow external member and drilling rod inwall are locked greatly.
(4), in axle center screw rod 5 lower end install detecting instrument 6, described detecting instrument, is provided with the installing hole 9 matched with the screw rod of axle center screw rod at an upper portion thereof, is provided with internal thread in installing hole, for detecting instrument 6 is locked at screw rod lower end, axle center.
See Fig. 3.The male joint 13 of the drilling rod A10 being hung with detecting instrument 6 is accessed the female joint 11 of adjacent drill pipes B12 by device again after installing, shaft bottom transferred to by the drilling rod after connecting, and can carry out measuring while drilling, and whole device and detecting instrument 6 do not affect and normally creep into work.When round trip creeps into end, from shaft bottom, well head is proposed drilling rod, drilling rod A10 and drilling rod B12 is dismantled, detecting instrument 6 is got off from axle center screw rod 5 lower end unloading, again nut 4 is down unscrewed from screw rod lower end, axle center, axle center screw rod up moves, until the external member that narrows is taken out after closing completely in drilling rod A10 male joint 13.
Embodiment 2: the utility model provides a kind of for hanging the locking device of detecting instrument at drilling rod inner chamber, its structure is substantially the same manner as Example 1, height unlike the cone 8 on the present embodiment axis screw rod 6 top be narrow external member length 4/5ths, the installation of device eliminates the step that rotating nut up pushes the external member 1 that narrows in addition, this is because the gravity of detecting instrument 6 falls down with axle center screw rod 5, axle center screw rod 5 upper cone body 8 external member 1 that narrows two struts male joint 13 inwall being clamped on drilling rod A10, realize detecting instrument 6 and be suspended on drilling rod inner chamber, again the female joint 11 of the male joint 13 of drilling rod A10 with the adjacent drilling rod B12 be connected is connected, the whole drilling rod being hung with detecting instrument 6 is transferred to shaft bottom, carry out measuring while drilling, the locking device installed and detecting instrument 6 do not affect drilling rod and normally creep into.
Locking device structure of the present utility model is simple, and difficulty of processing is little, and cheap, easy to operate, use safety is effective, is convenient to detecting instrument and carries out measuring while drilling, and this device and detecting instrument in use all do not affect normal rod boring.
