In above-described embodiment, as shown in figure 12, thrust ring 6 and sleeve 5 are for closely cooperating, when promoting thrust rings 6, the spacing ring 7 of urceolus 1 inwall moves upward, thrust ring 6 inwardly squeezes and pushes away arc card 8, arc card 8 is entered in the arcuate structure groove 51 of sleeve 5, and have part arc card 8 to charge into the inwall of sleeve 5, form the descending stuck point of three control jump bits 4.
In above-described embodiment, such as Fig. 9, Figure 10, shown in Figure 11, when the shoulder 1a of urceolus 1 inwall contacts with thrust ring 6 tops, jointly walk to structure grooves 51 places of sleeve 5 all when the same level position, arc card 8 distending cards lean against in the convergent shoulder 61 of thrust ring 6, three stuck points of sleeve 5 inwall support jump bits 4 are disappeared, and it is descending rapidly that spring 3 discharges elasticity kinetic energy drive jump bit 4, and the anvil 52 of jump bit 4 impingement sleeves 5 has been realized shake.
The shake method that rises of the utility model device may further comprise the steps:
1) as shown in Figure 9, when normally creeping into state, spring 3 is in the nature extended configuration, and be in fit-state between jump bit 4 and sleeve 5 anvils 52 this moment.And the convergent shoulder 61 of thrust ring 6 and the structure grooves 51 of sleeve 5 are in the same level position, and arc card 8 outside cards lean against in the convergent shoulder 61 of thrust ring 6.Focus is under the effect of the pressure of the drill, and its internal spline joint 10 is in fit-state with lower contact 11 always.Creep into moment of torsion by the spline pair transmission of sleeve 5, the pressure of the drill is by the contact transmission of internal spline joint 10 bottoms with lower contact 11.Focus can not produce jarring action, is a part of transmitting torque and the pressure of the drill as drilling tool.
2) as shown in figure 10, according to testing requirement, when having needed shake, at first stop drilling tool and rotate, on put on section's drilling tool, top connection 2 drives operating sleeves 9 one the same moving, the boss 91 of operating sleeve 9 promotes jump bit 4 and spring 3 moves on the whole, and this moment, spring 3 still was in the nature extended configuration.Spacing ring 7 is also along with urceolus 1 one the same moving.Since sleeve 5 terminal connection lower contacts 11, and lower contact 11 and mud motor and drill bit connect, and therefore keep transfixion by deadweight, and drill bit contact with the stratum still.
3) as shown in figure 11, when moving to arc card 8 upper end on the jump bit 4, spacing ring 7 contacts with thrust ring 6, the top drilling tool is also up in continuation, and it is up that spacing ring 7 promotes thrust rings 6, and the convergent shoulder 61 of thrust ring 6 inwardly squeezes and pushes away arc cards 8, arc card 8 is entered in the structure grooves 51 of sleeve 5, and the inwall that has part arc card 8 to charge into sleeve 5 forms the descending stuck point of three control jump bits 4, and support is in jump bit 4 bottoms, stop drilling tool on carry.
4) as shown in figure 12, transfer the top drilling tool, because it is descending that arc card 8 has limited jump bit 4, and top drilling tool drive top connection 2 continuation are descending, and then make spring 3 pressurized stored energies, and when driving urceolus 1 inwall shoulder 1a, top connection 2 comes downwards to when contact with thrust ring 6 tops, and this moment, spring 3 decrements were maximum, stored energy also reaches maximum value, and focus is in state to be excited.
5) it is descending that top connection 2 drives urceolus 1 continuation, when the structure grooves 51 that comes downwards to thrust ring 6 and sleeve 5 as shoulder 1a is in the same level position, arc card 8 is outside distending under the push effect of jump bit 4, get back in the convergent shoulder 61 of thrust ring 6, the stuck point of sleeve 5 inwall support jump bits 4 is disappeared, spring 3 discharges the anvil 52 of elasticity kinetic energy drive jump bit 4 rapid descending impingement sleeves 5 and realizes once rising shake, namely produces once significant signal.
6) after percussion action is finished, spring 3 returns to the nature extended configuration, and focus also returns to the original state of step 1).Repeat above-mentioned steps 2), 3), 4) and 5) action, namely can implement to rise shake next time.
For guaranteeing that the jarring signal is not subjected to external interference, after the action of putting on section's drilling tool is finished, need to close all power-equipments of rig after, finish again the impact process that the top drilling tool is transferred, to reduce noise to the impact of detection signal.
The various embodiments described above only are used for explanation the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents and improvement of carrying out on the basis of technical solutions of the utility model all should do not got rid of outside protection domain of the present utility model.
