Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
The logical cable formula drilling rod in a kind of center, as shown in Figure 1, comprises drilling rod body 7; Drilling rod body 7 one end are provided with single-core plug 3, and drilling rod body 7 other ends are provided with single core socket 11, between single-core plug 3 and single core socket 11, are connected through wire 8. Single-core plug 3 is fixed on jack part 1 through compressing plug screw 2, and jack part 1 is threaded with screw thread support ring 4, and screw thread support ring 4 is connected with the internal thread of drilling rod body 7 one end. Single core socket 11 is fixed on plug piece 9 through compressing plug screw 2, and plug piece 9 is connected with the internal thread of drilling rod body 7 other ends through support ring 10. Wire 8 overcoats have steel sheath 6, and steel sheath 6 two ends are threaded with jack part 1 and plug piece 9 respectively. The joint face of steel sheath 6 and jack part 1 and plug piece 9, and plug piece 9 is equipped with sealing ring 5 with the contact-making surface of support ring 10 and jack part 1.
Embodiment
The logical cable assembly in this routine drilling rod center as shown in Figure 1, is mainly made up of jack part 1, compression plug screw 2, single-core plug 3, sealing ring 5, steel sheath 6, wire 8, plug piece 9, single core socket 11. The single-core plug 3 that is welded with long enough wire 8 is arranged in jack part 1, and with compressing, plug screw 2 is fixing. Wire 8, through steel sheath 6 centre bores, is adopted and is threaded between steel sheath 6 and jack part 1, and seal by sealing ring 5. The wire 8 that passes steel sheath 6 is penetrated to plug piece 9 centre bores, between plug piece 9 and steel sheath 6, still adopt and be threaded, and seal by sealing ring 5. After steel sheath 6 has been connected with plug piece 9, weld with single core socket 11 8, single core socket 11 is packed in plug piece 9, and fixing with compressing plug screw 2.
Screw thread support ring 4 and support ring 10 are packed in drilling rod body 7, and connecting thread is smeared appropriate high-strength viscose and is fixed. Finally jack part 1 end is screwed into screw thread support ring 4, connecting thread is smeared appropriate high-strength viscose and is fixed, and adopts sealing ring 5 to carry out righting and be connected between plug piece 9 ends and support ring 10.
Because stube cable need to be arranged in logical cable formula drilling rod center, center, occupy certain structure space, in order to reserve enough air passing holes or flowing hole area, this body diameter of drilling rod is by standard drilling rod external diameter Ф 73mm design, its two ends screw thread specification adopts the logical cable formula drill rod thread of common central on existing market to design, thread taper is 1:30, realistic applicable cases. As shown in Figures 2 and 3, wherein screw thread support ring 4 centre bores are screwed hole to the structure of screw thread support ring 4 and support ring 10, for being connected and fixed jack part 1; Support ring centre bore is unthreaded hole, for righting plug piece 9. Between screw thread support ring 4 and support ring 10 circumference, all leave annular space 12, annular space area is 633mm2, meet actual operation requirements. The connection diagram of the logical cable drilling rod in Tu4Shi Lianggen center, after two drilling rods docking, the sealing ring 2 on plug piece 9 is for seal protection single-core plug socket joint, prevents from that extraneous foreign matter from entering in plugs and sockets, to cause short circuit. When drill rod thread is screwed at the end, the docking of single-core plug socket puts in place, thereby completes the connection of the logical cable drilling rod in center.
