Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2, Fig. 3 during accompanying drawing illustrates, the utility model is further illustrated.
As shown in Figure 1, a kind of vibratory impulse pipe nipple, pipe nipple top comprises shell joint 1 and internal spline cylinder 4, a pair point of spacer 2 therebetween, internal spline cylinder 4 inside is free-sliding spline axle 3, the inner axial hollow of free-sliding spline axle 3 is through, and upper end is threaded with shell joint 1 lower end, and free-sliding spline axle 3 lower end is that limited step is held concurrently packing_seal part 5; It is middle casing 10 in the middle part of pipe nipple, upper end is fixedly connected with internal spline cylinder 4 lower thread, middle casing 10 inside is provided with moushroom valve device, moushroom valve device comprises Moving plate valve 7 and quiet moushroom valve 8, quiet moushroom valve 8 is fixedly connected with middle casing 10 by lock-screw 9, quiet moushroom valve 8 axle center hole is used as Moving plate valve 7 bearing 16, and periphery through hole is as drilling fluid flowing hole 17; Pipe nipple bottom is lower house 12, its upper end is fixedly connected with middle casing 10 lower end screw thread, lower house 10 inside arranges shaft coupling 11, for providing fixed-axis rotation power for moushroom valve device, its upper end is fixedly connected with Moving plate valve 7 screw thread by upper connector 15, and lower end is connected with motor drive shaft 13 by lower connector 14.
With reference to Fig. 2, shell joint 1, internal spline cylinder 4, point spacer 2 and free-sliding spline axle 3 form axial active joint, axial active joint part adopts internal spline cylinder 4 and free-sliding spline axle 3 to provide axial displacement degree of freedom for it, active joint for splitting drill string, and ensures that the drill string separated can axially move and transmitting torque.
With reference to Fig. 3, moushroom valve device comprises Moving plate valve 7 and quiet moushroom valve 8, and Moving plate valve 7 rotates in fixed axis, and rotating shaft is through quiet moushroom valve 8.During duty, Moving plate valve 7 is tightly fitted with quiet moushroom valve 8 work plane under the effect of drilling liquid pressure, and ensure that the sealing of moushroom valve device work plane reaches requirement, quiet moushroom valve 8 periphery through hole is as drilling fluid flowing hole 17, Moving plate valve 7, for periodicity closed portion flowing hole, changes drilling fluid area of passage.
In use, shell joint 1 upper end is connected with power drilling tool bypass valve vibratory impulse pipe nipple of the present utility model, and lower house 12 lower end is fixedly connected with power drilling tool motor shell screw thread.Drilling fluid enters pipe nipple from shell joint 1, flows through free-sliding spline axle 3 endoporus, then flows through moushroom valve flowing hole 17, then enters motor through the outer annular space of described power transmission converting means 11.Motor rotary power is transferred to Moving plate valve 7 through power transmission converting means 11, thus drives Moving plate valve 7 to rotate, and periodically closes quiet moushroom valve flowing hole 17, changes drilling fluid area of passage.At moushroom valve device place, when closing quiet moushroom valve 8 flowing hole 17 in Moving plate valve 7 rotation process, drill string drilling fluid area of passage instantaneous variation is to minimum, now, mud flow rate can ensure that motor keeps on the go, simultaneously due to water attack effect, cause the pressure acted on quiet moushroom valve 8 upper surface sharply to raise, thus internally spline tube 4 and following drill string comprise drill bit generation percussion; When Moving plate valve 7 is rotated further the flowing hole 17 opening aforementioned cut out, drill string drilling fluid area of passage instantaneous variation to maximum, now, because water attack effect weakens, the corresponding minimizing of pressure on quiet moushroom valve 8 upper surface, internal spline tube 4 and comprise drill bit impact effect with lower drill and terminate.Along with the rotation of moushroom valve, vibratory impulse pipe nipple utilizes fluid power to provide periodically vibratory impulse for drill bit, the single of vibrating and percussive drilling breaks rock effect and combines with the broken continuously rock effect of rotary drilling, thus raising power drilling tool bores rate of penetration that is hard, abrasive layer.Wherein, drillstring vibrations frequency, impact force size by regulating mud flow rate, property of drilling fluid, the physical dimension of the pressure of the drill and Moving plate valve 7 and quiet moushroom valve 8 obtains.
